Archaeologists have discovered an unusual artifact they say could represent the earliest known use of written numbers ever discovered in Mesoamerica.

The curious clay figurine features eleven small dots carved into its surface, appearing in three columns. Although its exact purpose remains unclear, researchers who report the discovery in Latin American Antiquity believe it could be one of the oldest examples of graphic notation that may have been used for rudimentary calculation or some similar purpose, dating to as far back as around 750 B.C.

Significantly, the researchers behind the recent study argue that this earliest known evidence of numerical writing could offer clues to “the relationship between numeration, bodies, and identity in ancient Mesoamerican worldviews.”

The Enigma of the Tab Figurines

The figurine, roughly the size and shape of a small television remote, was unearthed at an ancient Mesoamerican site located along Guatemala’s Pacific coast, known as La Blanca. It is among a group of similar artifacts archaeologists call tab figurines, and hundreds of these mysterious relics are known from past discoveries at the site.

Named for their unusual slab-like appearance, these figurines also bear anthropomorphic qualities, which include depictions of jewelry and other ornamentation, although the tab figurines do not directly resemble human heads beyond the presence of such ornaments.

A Remarkable Discovery at Ancient La Blanca

While similar past discoveries recognized as tab figurines have been made at La Blanca, the presence of dots appearing in columns makes this one very unique and presents a novel possibility: that the impressions on the statuette may not have been purely decorative.

“The ordered dots on the La Blanca tab figurine’s headdress, of course, raise more questions than they answer,” write authors Julia Guernsey, Stephanie M. Strauss, and Michael Love in their recent study. “This is often the case with unique examples such as this, which cannot be better contextualized within a larger grouping of like objects from La Blanca or elsewhere.”

“Although one might be inclined to dismiss the La Blanca figurine as a curiosity or an isolated addendum to the complicated history of first writing in Mesoamerica,” the authors go on to note, “we believe that it merits this thorough discussion.”

Clues to Unraveling a Mesoamerican Mystery

A clue to the artifact’s purpose may arise from the association between tab figurines and the human head, a region of the body that is traditionally associated with individual identity. This is significant, since archaeologists recognize a potential link between numbers and individual identity in the world of ancient Mesoamerica.

Based on existing archaeological knowledge from the region, it is known that experimentation with numbers had already begun around the time the artifact is believed to have been made. One well-characterized numerical system is known as the dot-and-bar system, which, as the name implies, relies on dots and bars to convey figures of one and five units, respectively.

“In the Mixtec and Aztec codices, one easily becomes accustomed to reading even long strings of single dots and quickly approximating their quantity, a visuo-summation process known as subitizing,” the authors write.

“And no matter what form Mesoamerican numerals took, the vigesimal system was rooted in metaphors/mnemonics of the body: specifically, 10 fingers and 10 toes and concepts of personhood anchored to the number 20,” they add.

Also of significance is the K’iche’ word for person, winik, which is the same word used for the number 20, and for a simple reason: it refers to the ten fingers and ten toes of the human body.

Connections to Mesoamerican Personhood Concepts

Although the connections between the unique figurine unearthed at La Blanca and existing knowledge of Mesoamerican number systems are compelling, the researchers caution against interpreting the artifact solely through the lens of later Mesoamerican writing systems. One main reason why is that scholars think there probably wasn’t ever any single method for recording numbers across the region.

Still, the artifact nonetheless joins a growing body of evidence that could point to the fact that the inhabitants of La Blanca were experimenting with symbolic communication, and at a time centuries before fully developed writing systems emerged in the region.

While the exact meaning of the dots on the statuette remains unknown, the researchers behind the study make a compelling case for why the markings may have represented a name, a date, or another personal identifier. If correct, the placement of the dots may hint at an early connection between numeration, identity, and social expression during a period when some of Mesoamerica’s first urban communities were taking shape.

“Yet a question remains as to whether the identity expressed by the La Blanca tab figurine with its 11 dots was human, supernatural, or a combination thereof,” the authors concede, although concluding that their assessment of the artifact strongly points to the known associations between time, numbers, and the concept of personhood as envisioned in the minds of ancient Mesoamericans.

“Early Mesoamerican conceptualizations of time and the nature of being, perhaps, were not so very different from those of Aristotle for whom Paul Ricoeur noted, ‘Being in time [meant] more than existing when time exists. It [meant] ‘being in number.’”

The study, “Numbers and Bodies: Potential Early Numeration on a Middle Preclassic Figurine from La Blanca, Guatemala,” was published in Latin American Antiquity.

The James Webb Space Telescope (JWST) has revealed a cosmic catastrophe, as winds extinguished a star-forming galaxy in the early universe, offering new insight into earlier strange observations.

Cosmic winds may destroy entire galaxies, according to new JWST research exploring the lingering mystery of why certain parts of the universe are unexpectedly devoid of growth.

The findings were published in a recent paper in the Monthly Notices of the Royal Astronomical Society, revealing galactic-scale death in a universe just one billion years old, and potentially answering questions about previous troubling JWST observations.

James Webb Space Telescope Observation

Observations made by the JWST revealed cold gas, an essential star-forming material, blowing out of the CRISTAL-2 galaxy in a massive plume, severely degrading its ability to produce new stars. According to the researchers, it would take less than 50 million years for the galaxy to be completely dead if this activity keeps up, a mere blink in the scheme of a 13.8 billion-year-old universe.

Astronomers consider galaxies to be “dead” if they are no longer capable of producing fresh stars. Traditionally, astronomers expected that it would take billions of years for an old galaxy to slowly run out of fuel and burn out. However, JWST observations have continually captured events in the early universe that were not expected to occur until much later.

One of these was finding a host of dead galaxies in the early universe shortly after it first became operational in 2022. How galaxies could die so close to the beginning of the universe, without sufficient time to burn through their cold gas supplies, has long perplexed scientists.

Explaining Galaxy Death

As researchers began considering various explanations for the phenomenon, they initially settled on dark energy, essentially explaining one unknown with another. Dark energy is a theoretical substance that scientists believe drives the expansion of the universe and was once a stronger force than it is now. While the Dark Energy Spectroscopic Instrument survey revealed last year that dark energy appears to be weakening over time, an exotic galaxy-killer is not required, according to this latest research.

Instead, researchers offer a much simpler explanation of powerful cosmic winds in the remote past. Conventional thinking has it that such powerful winds could only be generated by a supermassive black hole, yet these new observations challenge that assumption.

JWST Reveals the Culprit

CRISTAL-02 is a galaxy still in the making, composed of several smaller galaxies in the final stages of merging into a single system. Because the early universe was far denser than it is today, such collisions were much more common. During these mergers, gravitational forces funnel vast amounts of gas toward the galactic centers, triggering intense bursts of star formation.

Observations of CRISTAL-02 by the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) revealed a star formation rate roughly twice that of similar galaxies. Ironically, this extraordinary burst of stellar activity is also generating a powerful cosmic wind that is stripping away the very gas needed to form new stars.

Compounding the effect, many of the newly formed stars rapidly exhaust their fuel and end their lives as supernovae, producing additional outflows that further deplete the galaxy’s star-forming material.

Together, these processes appear capable of shutting down star formation far more quickly than astronomers previously believed possible. Going forward, ongoing JWST observations are likely to continue challenging astronomers’ assumptions, as more evidence indicates that nearly half of the early universe’s massive galaxies were interacting—a finding which also suggests early “galactic deaths” like these may not be all that rare, after all.

The paper, “Multiphase Images of a Powerful Supernova-Driven Wind in the Early Universe,” appeared in Monthly Notices of the Royal Astronomical Society on June 10, 2026.

Over two years after Japan’s Smart Lander for Investigating Moon (SLIM) mission deployed a tiny, shape-shifting rover on the Moon, the country’s space agency JAXA has finally revealed previously unreleased details about the first-of-its-kind autonomous robotic lunar exploration.

According to a statement announcing the recently published mission account, the SLIM team deployed the rover on the Moon’s surface, “after which the rover transformed from a tiny sphere into a wheeled robot that took images of the lander and its environment.” A second rover transmitted the data back to Earth, with all steps occurring autonomously.

The team behind the historic mission said their success could pave the way for swarms of small, transformable robots capable of exploring high-scientific value areas that larger spacecraft and robots cannot reach, including caves, tunnels, lava tubes, vents, and deep extraterrestrial craters.

The Benefits of Tiny Robots and Autonomous Shape-Shifting Rovers

In the published study, the JAXA team explains that robotic technologies like SLIM “are expected to drive substantial advancements in planetary exploration and resource prospecting” by performing tasks in extraterrestrial environments that are inaccessible to other platforms, including human astronauts. For example, the team noted that miniature robots offer tremendous weight savings over bulkier platforms, especially when added to missions with “strict payload limitations.”

“Miniature robots have the potential to reduce payloads and to reach cramped spaces such as small vents and craters that are inaccessible to larger, conventional robots,” they explain.

Still, the SLIM team notes that building tiny, shape-shifting rovers capable of exploring a variety of complex environments presents its own set of challenges. The most limiting constraints involve computational power and battery capacity. The team also observed that smaller robotics platforms inherently suffer from “reduced locomotion performance” due to their small size.

Now, when revealing the details of the SLIM mission, the researchers note that advancements in miniaturization and computational performance spurred by the Internet of Things “have catalyzed the emergence of smaller, lighter, and more intelligent rovers at lower costs.”

Introducing the ‘Hopping’ Lev-1 and the ‘Transforming’ Lev-2

To build a tiny, shapeshifting robot capable of exploring the lunar surface autonomously, team leader Daichi Hirano and colleagues designed the Lunar Excursion Vehicle (LEV) system, which comprises LEV-1 and LEV-2. According to the team’s statement, LEV-1 can communicate directly with mission planners back on Earth. For locomotion, the robot moves via what the team termed “a controlled hopping mechanism.”

The second robot, LEV-2, starts out as a compact sphere 8 inches in diameter. However, once on the Moon, the mission controllers said that the tiny robot can transform into a “two-wheeled rover with cameras and a tail stabilizer.”

“Here, we introduce a two-wheeled centimeter-scale rover, designated Lunar Excursion Vehicle 2 (LEV-2), also known as SORA-Q (named after the Japanese words for space and sphere), which transforms into a wheeled configuration from a compact spherical form, enabling efficient traversal of soft lunar terrains,” they write.

Transformers Make Autonomous Robotic Exploration History

According to the new mission details, the SLIM lander deployed LEV-2 “immediately before its landing on the lunar surface.” In the mission details, the team explained that upon deployment, the rover autonomously extended its wheels, tail stabilizer, and cameras, “thereby enhancing its mobility and stability on soft lunar terrain.”

After deployment, LEV-2 navigated the lunar surface in the immediate area around the lander. According to the published study, “the palm-sized rover accomplished autonomous lunar exploration by navigating around the SLIM lander, capturing images of both the SLIM lander and its environment.” Critically, the rover’s exploration was autonomous and “without reliance on ground-based teleoperation,” marking a historic first in lunar exploration.

After finishing its exploration, the tiny robot transmitted images of its adventures to LEV-1. The hopping rover then transmitted the data to Earth. The team notes that all these steps were also accomplished autonomously.

The team notes that the LEV-2 shape-shifting rover operated for “more than 100 minutes: before losing communication with LEV-1. Although determining the exact cause may require direct examination of the two robots, Hirano’s team suspects that issues caused by LEV-1’s hopping motions or battery depletion “may have contributed to connectivity issues.”

Exploring High-Risk, Scientifically Valuable Environments

When discussing the implication of an autonomous, shape-shifting rover successfully navigating the lunar surface and completing its mission directives, the team concedes that the capabilities of a single, small rover like LEV-2 “are inherently limited.” However, they also note that their mission success highlights the potential of this category of robotic platform “as independent explorers, capable of accessing environments beyond the reach of a primary large spacecraft.” 

“Swarm-controlled small robots are poised to be deployed in high-risk yet scientifically valuable environments, such as vents, caves, and steep slope craters, that are inaccessible to larger, conventional rovers,” the researchers conclude. “This approach promises to enhance both the efficiency and safety of future planetary surface exploration.”

The study “From ball to rover: Transformable palm-sized rover SORA-Q for autonomous lunar exploration” was published in Science Robotics.

Astronauts selected for NASA’s Artemis missions are traveling to outer space in style, the American space agency has revealed.

On June 7, Axiom Space and fashion empire Prada showcased their Liquid Cooling and Ventilation Garment (LCVG), designed to be worn by astronauts inside the Axiom Extravehicular Mobility Unit (AxEMU) spacesuit. 

The unveiling of the new garment by Prada and Axiom Space took place at Prada’s SoHo location in Manhattan just days before the announcement of the Artemis III crew, according to the New York Times fashion desk. With black-clad waiters circulating champagne and healthy juices through the Rem Koolhaas-designed venue, the intersection of fashion and space exploration was once again on full display.

“The future of space exploration will not be built by any one entity alone, and our partnership with Prada is proof of that,” said Dr. Jonathan Cirtain, Axiom Space CEO and President, in a statement.

“By bringing together the best in both aerospace engineering as well as luxury craftmanship and advanced product development, we have developed a garment that neither company could have created independently, and that is exactly the kind of cross-industry thinking that will define the next era of human spaceflight,” Cirtain added. 

Some might be surprised to learn this is not the first time NASA has collaborated with a fashion house. The first modern spacesuit was designed and crafted by a group of international designers at the Latex Corporation (ILC). In the 1960s, this company was best known for manufacturing bras and girdles.

Notably, a version of its A7L spacesuit was worn by Neil Armstrong during the Apollo 11 mission. Designers developed the A7L to protect astronauts from the harsh conditions of space and the lunar surface.

The suit was constructed using materials such as neoprene, Beta cloth—which helped protect astronauts from extreme temperatures—and aluminized Mylar. Overall, it was a highly complex, multilayered design.

The new LCVG collaboration draws on Prada’s expertise in knitting, craftsmanship, and advanced design. The resulting garment is a next-generation system developed using sophisticated 3D modeling techniques.

The suit is designed to maintain cooling and ventilation while remaining comfortable during spacewalks lasting up to eight hours. Thanks to its high-performance materials, it can also be worn repeatedly during long-duration missions.

“When we unveiled the AxEMU, we announced that the collaboration between Prada and Axiom Space would continue beyond that first milestone,” said Lorenzo Bertelli, Prada Group Chief Marketing Officer and Head of Sustainability, in a statement. 

“Today, we are proud to present a new achievement born from the unique combination of Axiom Space’s pioneering expertise and Prada’s know-how in design, patternmaking, and advanced materials, ahead of humanity’s return to the lunar surface,” Bertelli added.

In 2024, Axiom Space and Prada unveiled the AxEMU’s outer layer, designed to withstand the harsh conditions of the lunar South Pole. Their latest collaboration on the Liquid Cooling and Ventilation Garment builds on that partnership, focusing on astronaut comfort, thermal regulation, and reliability inside the spacesuit.

“We look forward to continuing this collaboration with Axiom Space, pushing boundaries and exploring new frontiers together,” adds Bertelli.

The LCVG keeps astronauts cool during spacewalks by circulating chilled water through tubes woven into the garment, removing body heat and venting it through the spacesuit. It also delivers fresh oxygen and removes carbon dioxide, helping astronauts remain safe and comfortable in the harsh environment of space.

“Every minute astronauts spend outside their vehicle, the LCVG is working to keep them safe,” said Russell Ralston, Axiom Space Senior Vice President of Spacecraft Development.

“It manages their thermal environment, supports their breathing, and does it all while they’re pushing their bodies to the limit,” Ralson added. “The work we have done with Prada has taken that capability to a level we could not have achieved alone.”

Archaeologists say bones unearthed from an Iron Age burial in Scotland are revealing new insights into how human remains were interred in ancient Europe, in a region with scant evidence for mortuary practices in the archeological record.

Among the new findings, cuts within the skull of a woman’s 2,000-year-old Iron Age remains suggest the removal of her brain prior to burial, along with other evidence of mortuary processing. 

“Manipulation of one skeleton, including the possible removal of the brain, fashioning of long bones into ‘tools’ and reassembly for burial, suggests complex mortuary processing,” write the authors of a new study published in the journal Antiquity. 

Iron Age Remains

The study’s authors report that the woman’s remains, and those believed to have belonged to a teenage boy buried nearby, both had distant origins, adding to the intrigue. Archaeologists discovered the pair buried in a cairn in Sutherland’s Loch Borralie in northwest Scotland, a rare find in such well-preserved condition. 

Due to Britain’s acidic peat soil, few Iron Age human remains have been recovered, leaving many questions about the inhabitants’ funerary practices. This particular corner of Scotland is an exception, with an environment better suited to preserving bone, offering a rare window into this mysterious period.

“To find bodies of this age so well preserved is rare, but to discover evidence of a funeral ritual we previously knew nothing about was such a surprise and very exciting,” said lead author Dr. Laura Castells Navarro.

Unusual Mortuary Practices

“The adult female displayed incisions on the inside of her cranium, suggesting her brain had been intentionally removed after death,” Castells Navarro continued. “We have no other comparison of this type of practice, but we know that the dead were curated and treated carefully in Iron Age Britain, so our understanding is that this bone modification is within that same tradition of care.”

The sharpened bones, which the archeologists suspected were used as tools, included humeri, ulna, and femur. Why Iron Age Britons would have engaged in such elaborate and unusual manipulation of skeletal remains eludes archaeologists, although they note that the care evident in reassembling her skeleton for burial suggests she commanded the respect and reverence of those who laid her to rest.

Analysis techniques used on the bones include isotope testing and DNA mapping, revealing a close kinship suspected to be that of maternal second cousins.

Iron Age Connections

More intriguing than their relationship is the evidence of the distance they had traveled, as isotopic analysis revealed that the pair had grown up 50 miles to the southeast. Genetics pushed this even further, revealing family connections beyond the mainland, spreading out in opposite directions. To the northeast, they had relatives 108 miles away on the Orkney Islands, while to the southwest, they had kin 140 miles away at Applecross.

Archaeologists interpret this to mean that Iron Age Britons were extremely mobile, traversing water in family groups.

“Our research shows that prehistoric maritime communities periodically moved around the north coast and Northern Isles of Scotland, possibly in small groups,” Dr. Castells Navarro said. “This movement allowed for the spread and maintenance of cultural practices and traditions.”

With individuals of shared kinship spread so far, researchers suggest these complex mortuary practices were likely shared across Iron Age Britain, adding an intriguing new wrinkle to our assessment of these ancient people.

“I think we can assume that the Iron Age dead were not forgotten,” Dr. Castells Navarro concluded, “and still had meaning to the living, with a continued interaction between the living and the dead across time and distance.”

The paper, “Reconnecting the Dead in Iron Age Britain: Funerary Processing and Long-Distance Connectivity at Loch Borralie, Scotland,” appeared in Antiquity on June 10, 2026.

The nature of time has long puzzled scientists, and now one researcher at the University of Birmingham has constructed a mini-universe in a laboratory to get to the bottom of this and other fundamental questions about gravity and quantum mechanics.

Revealed in a recent paper published in Physical Review Research, Professor Giovanni Barontini created a universe in a sealed quantum system to answer the lingering questions of “what is time?” with a laboratory model. His work creates an intriguing new testbed for exploring the nature of our universe from beginning to end, and all the phenomena in between.

Creating a Universe

Physicists have long puzzled over how a sequence of events could be understood in a universe without an external clock. The new work demonstrates how to move purely theoretical work into a practical laboratory environment, allowing exploration of deep questions about time and quantum physics.

In the new paper, Professor Barontini describes creating a miniature universe from 24,000 atoms held at just several degrees above absolute zero. Such temperatures are essential to many quantum explorations, including quantum computing technologies.

In this quantum system, the hermetically sealed cloud of ultracold atoms acts like a miniature universe. A thin barrier divides this tiny universe in half, while two lasers set to different frequencies bombarded it to create an observed bright region and an unobserved dark region.

Internal Time

Crucial to the experiment, Barontini did not measure time externally but instead waited for the internal relationship between the particles to generate time within this new universe. This idea comes from theoretical physics concepts such as the Wheeler-DeWitt equation, which posits that the universe exists in an ever-steady quantum state exhibiting both wave- and particle-like behavior, without an external time.

Barontini observed the bright side behaving similarly to our universe, albeit on “fast-forward,” repeating a cycle of Big Bangs and Big Crunches, continually expanding and collapsing back in on itself. Since the sequence of events could be reconstructed entirely within the quantum system without reference to a laboratory clock, this shows that time emerges from the system itself, created by the disorder of spreading atoms, rather than being an external function.

Investigating Quantum Time

Time moved forward in a single direction, with the increase or decrease in particles in the bright sector as they moved into the dark sector and back again, indicating an arrow of time. Yet, when the atomic distribution remained steady, Barontini observed a halt in time, leading him to describe what he witnessed as “entropic time.”

While this version of time corrects the order of events, it is not steady; it varies with the system’s entropy level. Notably, Schrödinger’s equation, the linchpin of quantum theory, still works in entropic time.

“In some theories of the universe, especially quantum gravity, time doesn’t appear as a built‑in feature,” Barontini said. “Yet in everyday life, time flows from past to future – why is this so, when most basic laws of physics work the same way forwards and backwards?”

“This study provides the first controlled experimental evidence that ‘time’ can be defined by changes within a system rather than as the external ‘ticking clock’ we think of as time,” Barontini concluded. “It offers new insight into the nature of time in quantum gravity that could be used to describe dynamics just as effectively as conventional time.”

Moving forward, such artificial universes could be used to probe the mysteries of our own universe, including its earliest moments, the emergence of time, and even black holes.

The paper, “Testing the Problem of Time with Cold Atoms,” appeared in Physical Review Research on June 11, 2026.

Archaeologists believe a site in present-day northern Iraq may preserve the remains of an ancient city whose fall was recorded in texts from ancient Mesopotamia.

While ancient texts described the event, the physical traces were not discovered until recently. Excavations at Kurd Qaburstan in the Kurdistan region have now revealed the clearest archaeological record of Middle Bronze Age siege warfare found in the area.

During the 2024 and 2025 excavation seasons, a team led by Tiffany Earley-Spadoni, associate professor of history at the University of Central Florida and director of the Kurd Qaburstan Project, recovered 20 cuneiform tablets and more than 100 administrative sealings from destruction layers inside the Lower Town East Palace.

A Lost Archive

This collection represents the first substantial group of cuneiform texts found on the Erbil Plain, and their dating is unusually precise. Scribes wrote several tablets within days of one another, clustering around the period recorded as the city’s fall, which allows researchers to closely align the archaeological and historical records.

Epigraphers Paul Delnero and Parker Zane, from Johns Hopkins University and Yale University, are leading the translation effort with art historian Marian Feldman. The texts include palace administrative records and at least one letter that may mention a senior official from the ancient city of Qabra.

Some inscriptions may also correspond to destructions recorded on the Victory Stele of Dadusha, a monument that documents military campaigns in the region from the same period.

Burned Layers

The physical signs of the attack are clear. Collapsed buildings, burned layers, and numerous broken pottery pieces all show signs of a coordinated and sustained assault. The team found two layers of destruction, one above the other, which match the recorded events of Qabra’s conquest.

Within these layers of destruction, bioarchaeologist Andrea Zurek-Ost of Michigan State University identified the remains of 17 people. Several seem to have died where they fell, possibly including palace workers. Archaeologists found one individual face down over a stone basin. Researchers are now using isotopic and ancient DNA analyses to learn more about who these people were, where they came from, and how they might have been related.

Mapping The City Before It Fell

The destruction layers tell the story of the city’s final chapter. A magnetometer survey covering over 80 hectares provides a picture of what the city looked like before its fall.

Led by Andrew Creekmore III at the University of Northern Colorado, the survey detects buried structures by measuring changes in the Earth’s magnetic field. It revealed a monumental wall with bastions surrounding the site, fortifications that match those shown on the Victory Stele of Dadusha and support the identification of Kurd Qaburstan as ancient Qabra.

Researchers also found a preserved street with a drainage system, along with areas used for food processing and textile production. These features indicate that the city was more complex than researchers usually expect in northern Mesopotamia.

Mesopotamian history has often focused on southern cities such as Uruk, viewing the south as the birthplace of urban civilization. The evidence from Kurd Qaburstan challenges that view.

“The evidence from Kurd Qaburstan shows that northern cities could be large, complex, and politically significant, with administrative systems, fortifications, and infrastructure comparable to those of the best-known southern sites,” Earley-Spadoni says.

Findings from the Kurd Qaburstan Project were announced as part of a reports and proceedings release supported by the University of Central Florida and the U.S. National Science Foundation.

Thousands of years ago, Scotland’s early inhabitants were building mysterious artificial islands in lakes throughout the region—and now archaeologists have uncovered evidence that reveals these curious aquatic features to be far older than once thought.

Scattered throughout Scotland’s ancient lochs, these curious structures—known as crannogs—have long intrigued archaeologists and historians, partially due to the questions about their age.

Now, artifacts recovered from these human-built islands are pushing back the timescales on their construction, causing researchers to have to reconsider the origins of one of the most enigmatic lacustrine features in the British Isles.

The Crannog Enigma

Crannogs have been known to archaeologists for some time, with some of the earliest extensive explorations of these features undertaken beginning more than a century ago by Odo Blundell, a monk at Fort Augustus Abbey.

Constructed mostly from stone and timber, speculations about their creation extend to as early as the Bronze Age, although most scholars believe these curious features were likely to have been an invention of the Iron Age.

However, a surprising recent discovery is now challenging that presumption, revealing that some of these artificial islands date back to more than 5,000 years ago, having been built during Scotland’s Neolithic era.

Older Than Previously Thought

The story began to unfold in 2012 when local diver Chris Murray was exploring a crannog near the Isle of Lewis in Scotland’s Outer Hebrides. There, he discovered fragments of ancient pottery that experts at the National Museum of Scotland later examined, revealing an astonishing discovery: the remains of artifacts unequivocally associated with the Neolithic period.

The implication was obvious: for Neolithic pottery to have been found on this crannog would indicate it must have been constructed thousands of years earlier than the past dating of these artificial islands.

The discovery prompted a deeper look at the region’s ancient artificial islands, which soon revealed additional evidence of their Neolithic provenance. During the research, Stephanie Blankshein, a maritime archaeologist at the University of Southampton, and colleagues discovered that organic materials and artifacts from several sites across Scotland’s Outer Hebrides indicated these crannogs were likely built sometime between 4,000 and 2,500 BCE.

At least 11 crannogs in the region, Blankshein and her colleagues say, were created during the Neolithic period, pushing back the date of their construction to as far back as six thousand years ago.

Rethinking the Lives of the Ancient Scots

One of the most intriguing aspects of the team’s findings involves what it reveals about the ingenuity of the early farming communities in the British Isles, since the new dating of these prehistoric artificial islands indicates that they must have been constructed within just a few centuries of when their ancient builders arrived in the region.

Such findings align well with past genetic studies, which indicate that the region’s Neolithic populations likely descended from farmers who made their way from the Near East through Europe, and eventually settled in the British Isles, where they made their new homes by the sea.

It remains unclear, however, whether the construction of crannogs had been an innovation that occurred after they arrived in Britain, or if this had been a much earlier practice these people brought with them.

Discoveries at the Loch Bhorgastail Crannog

Among the most remarkable crannog sites is one found at Loch Bhorgastail on the Isle of Lewis. This artificial island was initially believed to have been primarily built from stone, with some evidence of timber used as reinforcement.

However, underwater excavations by Blankshein and her colleagues soon uncovered something very surprising hidden below the crannog: a massive timber platform supporting the entire structure.

“As excavation advanced, it quickly became apparent that the terrestrial and underwater components formed a single continuous structure spanning both environments and could not be treated separately,” Blankshein and her colleagues write in a recent study detailing their research at the site.

During their underwater surveys, the team discovered that the wooden foundation extended beneath the entire island and dated to between 3500 and 3300 BCE. Measuring approximately 75 feet (23 meters) across, the platform may have originally sat in shallow water or even remained dry during parts of the year.

“Loch Bhorgastail provided a rare opportunity to develop, test, and refine a workflow capable of achieving terrestrial-grade accuracy underwater,” the research team writes. “The site demonstrates the potential of shallow-water archaeology to bridge the land–water interface while elevating the precision and reliability of underwater recording.”

Lingering Questions

A fundamental question that remains about these curious Neolithic constructions has to do with what their purpose was.

One clue may arrive in the form of residues found on the recent pottery discoveries at several of these sites, which indicate they were used to transport food. This may suggest the crannogs were locations where ancient people prepared and consumed meals, possibly during ceremonial gatherings.

However, it is also possible that these ancient structures served multiple purposes, ranging from sites for communal feasting to possible locations for meetings.

Despite the lingering questions about their use by Scotland’s ancient inhabitants, Blankshein and her colleagues saw these marvelous Neolithic structures as an ideal target for high-resolution shallow-water photogrammetry, which became the focus of her team’s recent research.

“Coastal, riverine, and lacustrine environments have played a central role in the development of human societies, yet locating and documenting this record of activity in littoral environments has proven difficult,” the team writes.

As a result of their research, the team’s findings, combined with recent archaeological discoveries from over the last decade or more, help to shed new light on Britain’s ancient past, while advancing the development of new archaeological approaches. This includes groundbreaking methods for creating 3D models of shallow underwater sites, which the team achieved by using paired action cameras.

As investigations continue, Blankshein and her colleagues suspect many more Neolithic crannogs remain hidden beneath the waters of Scotland and Ireland, and with their discovery and investigation, the potential for further advancements in understanding Europe’s earliest farming societies.

James Webb Space Telescope (JWST) observations of what astronomers call “little red dots” have intrigued researchers since their discovery in 2022.

Now, new data on the spectra of one of these dots, made possible with imagery obtained by Webb, may hold the answers researchers have long sought.

In a recent paper published in The Astrophysical Journal, a team of astronomers led by the University of Texas at Austin’s Vasily Kokorev revealed their intriguing observations of the little red dot GLIMPSE-17775 using the JWST.

Data collected by the JWST support the BH* scenario, the hypothesis that little red dots are supermassive black holes surrounded by a cloud of partially ionized gas.

JWST and the Little Red Dot

The recent JWST observation of GLIMPSE-17775 is the deepest spectral view of a little red dot ever captured, spanning 40 spectral lines and offering a powerful opportunity to compare the data with various theories about the object’s origins. Born only about 1.8 billion years after the Big Bang, or about 12 billion years ago, the object hails from the universe’s early days.

As with many of science’s most interesting discoveries, this observation was a fortunate accident, captured as the JWST was observing the Abell S1063 galaxy cluster, located in front of GLIMPSE-17775 from our point of view.

Gravitational lensing magnifies GIMPSE-17775, allowing JWST a better look at the object despite its extreme distance, and making the 30-spectrum JWST captured equivalent to hours of observations. 

“When we saw the spectrum for the first time, it was like having all the pieces of a puzzle scattered on the floor,” said Kokorev. “We picked up each piece of the puzzle, measured the lines, and started combining the different pieces into a mosaic. Maybe a few pieces looked like nothing at first, but then a couple of them came together, and we realized that there was something there.”

Explaining Little Red Dots

First appearing at around 600 million years after the Big Bang, the mysterious little red dots have puzzled scientists since they first came to light. The black hole scenario is just one of several that researchers have proposed as a possible explanation, although it is currently gaining the most support as more data comes in.

“I think part of the scientific community is converging on a singular picture — that little red dots can be explained by black hole star models. But none of the previous little red dots have all of the pieces of evidence in the same place,” Kokorev said. “With GLIMPSE-17775, we can test these models because of how deep and amazing this source’s spectrum is.”

The researchers interpret the data as showing a rapidly accreting black hole covered by a dense gas cocoon that reprocesses the black hole’s light into the spectrum observed by JWST.

Comparing the spectra to various models revealed some intriguing evidence for the BH* scenario. The helium, oxygen, and hydrogen lines don’t fit a simple rotating gas cloud model, but do correspond to an electron scattering, a broadening effect associated with a dense, layered gas cocoon.

Other lines, such as the 16 iron lines, suggest a powerful energy source, which could indicate a rapidly accreting black hole. Additionally, helium absorption and fluorescence are seen in the spectrum, signs that a powerful energy source is enveloped in a dense medium.

What JWST Didn’t See

Beyond this incredibly deep spectrum, other little red dot observations have been faint in X-rays, a form of emission that the gas cocoon, in the BH* scenario, is likely to absorb.

One strange quirk of GLIMPSE-17775 is that the spectrum was missing the portion that would indicate the little red dots’ signature dip in light emission, known as a Balmer break. However, supplementary data collected by the Hubble Space Telescope resolved this issue, identifying that interference from a giant host galaxy is the root cause.

“Everything fits, nothing is broken, and I think that makes the puzzle that is our universe even better,” Kokorev concluded. “Looking ahead, I’m eager to dive deeper and learn about what is powering the central engines of little red dots. While we think it’s a black hole, there are some other interesting theories being proposed, which is exciting. Maybe in a year or two, we’ll have the final answer to what powers these sources.”

Nearly three out of every four images obtained by NASA’s new SPHEREx space telescope revealed something many astronomers were afraid of: contamination by artificial objects humans are launching into space.

The findings were reported in a new preprint paper by researchers at NASA’s Ames Research Center, who say that 73.3% of all the images the telescope captured over four months last summer revealed evidence of at least one trail left by SpaceX satellites or other orbital spacecraft.

What may be worst of all is that astronomers aren’t surprised.

With its mission to map the night sky in near-infrared light, NSA’s Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) relies on long-exposure imagery that enables it to map large regions of the sky with every viewing.

Unfortunately, long-exposure photography is also ideal for capturing the movement of satellites, an increasing number of which have been placed in orbit in recent years.

Equally troubling is the fact that SPHEREx, from its own position in Earth orbit, had been positioned at an altitude where it was hoped that the number of satellite streaks could be limited. Yet despite such efforts, the new paper featured at the arXiv preprint server reports that, on average, at least two satellite trails were detected in every exposure.

Satellites Mistaken for Cosmic Rays

Astronomers have been raising concerns about this problem already for some time, and presently, there doesn’t appear to be any near-term solution.

Even beyond image contamination, the preprint study also found that several satellites that enter SPHEREx’s field of view are bright enough that they are also triggering the space telescope’s automated system that protects its delicate components from stray cosmic rays.

Designed to shut down the telescope’s data collection when it detects what it suspects are cosmic rays, the new research reveals that some satellites reflect enough light to engage algorithms that control this defense system.

Even in instances where imagery is successfully obtained, albeit with contamination from satellites, the brightness of these orbital objects can effectively obscure objects behind the portions of the telescope’s images where the satellites appeared.

A Growing Concern

The new SphereX findings are only the latest indication that astronomers were right to be concerned about potential light pollution from satellites. In a past study by Sando Kruk and colleagues, Hubble Telescope images had shown an increase in the number of satellites crossing its field of view, rising from contamination shown in just 2.8% of its images, to 5.9% over a period of two decades.

Ideas about how to prevent the issue have focused on using anti-reflective coatings on satellites and other means of reducing their brightness once they reach orbit. However, many modern satellites are large enough that having darker exteriors doesn’t help to significantly mitigate the amount of light they can reflect.

Additionally, the study’s authors note that “Optical reflections are just a fraction of the problem, since satellites also emit and reflect [infrared],” meaning that optical darkening efforts “might even increase their temperature, making them brighter in the IR.”

Worse Before It Gets Better

According to the study’s authors, the problem is likely to worsen before astronomers see any improvements.

“Remarkably, some private operators have announced the intent of deploying 4000 purposely high reflective satellites,” the researchers write, which aim to provide “sunlight on demand.” Such artificial orbital systems, if successfully deployed, would reflect light as much as five times the brightness of the full Moon onto areas of the Earth roughly five kilometers in diameter.

This, the team argues, would potentially have “a catastrophic impact to the quality of the dark sky and the Earth’s inhabitants.”

Fundamentally, the authors hope that bringing additional attention to such issues with their recent study may help to mitigate future concerns about our ever-brightening night sky.

“The widespread contamination addressed in this paper affects multiple areas of astronomical research,” the team says, which they say includes “the study of transient phenomena, deep imaging surveys, spectroscopic studies, and the search for Near-Earth Objects (NEOs), thereby hindering our ability to understand the Universe and protect the Earth.”

The new paper by Alejandro S. Borlaff and colleagues, “SPHEREx confirms predictions for artificial satellite trail pollution in Low Earth Orbit,” appeared at the preprint arXiv server.

Researchers from the Université Polytechnique Hauts-de-France have revealed a technique that successfully analyzed several Vincent van Gogh artworks at a microscopic level to correctly identify well-known, previously identified forgeries from recently authenticated ones

The research team behind the pioneering, non-invasive art authentication process said their approach could provide museums, collectors, and art auction houses with a previously unavailable tool with a proven, scientifically based track record for identifying fake or counterfeit art.

Using Microscopic-Level Surface Scans to Foil Art Forgery

According to a press release announcing the successful counterfeit identification tests, art forgery is an increasingly complex problem. However, the traditional approach of expert opinion combined with historical research and invasive pigment analysis has not always proven successful, with the study authors noting that such methods are “often inconclusive,” leaving museums and collectors to shoulder most of the risk for difficult-to-authenticate works.

More recently, collectors and auctioneers have turned to science for answers, including a report showing that AI may have identified as many as 40 counterfeit artworks sold on online marketplaces. Although no counterfeit versions of Van Gogh’s works were found, that same effort identified potentially fake versions of paintings by Monet and Renoir that were indistinguishable from authentic ones.

In 2023, researchers at the University of Sydney announced the development of a cutting-edge microscope capable of surpassing the diffraction limit. In that story, study co-author Professor Boris Kuhlmey noted that the method, which is ideal for identifying microchip irregularities, “could even be used to reveal hidden layers in artwork, perhaps proving useful in uncovering art forgery or hidden works.”

Last month, The Debrief reported the discovery of a mathematical pattern in many famous expressionist artworks, noting that many abstract artists may naturally arrange shapes and patterns in similar ways, even without knowing the mathematics behind them. If correct, this concept could use science and mathematics to separate fake Impressionist works.

Now, the Université Polytechnique Hauts-de-France team says their new approach takes modern technology a step further, resulting in an unprecedented level of accuracy.

“Fractal Analysis Gives Us a Measurable Fingerprint of an Artist’s Brushwork” 

Unlike the above techniques, the new approach analyzes the texture of a painting’s surface at the microscopic level by converting high-resolution images into three-dimensional surface ‘maps’ of the painting’s upper layers. According to the study authors, the extracted “texture” of a painting allows them to measure an image’s roughness and detail using fractal math. For example, the team said that the subtle patterns of an artist’s brush stroke are so consistent “that they act like a morphological signature unique to that artist.” 

“Fractal analysis gives us a measurable fingerprint of an artist’s brushwork without needing to sample or disturb the painting,” explained Francois Berkmans, the study’s lead researcher.

To test their approach, the researchers scanned several artworks attributed to Renaissance artist Vincent van Gogh. The researchers also used their technique to study the mathematical texture of an artwork called The Plowmen, which the team noted is a “well-documented fake.” Last, they used their method to analyze another Vincent van Gogh work, Sunset at Montmajur, which was authenticated in 2013.

After running their microscopic surface analysis, the team’s new system identified The Plowmen as a “strong outlier” compared to the artist’s other works. Conversely, the new method determined that the two newly authenticated paintings “aligned closely with Van Gogh’s known works.”

New Method “Strengthens” Traditional Analysis as a Complimentary Tool

When discussing the study’s results, Berkmans said their technique “can clearly point out genuine artists and reliably detect known forgeries.” Along with identifying fakes and authentic works, the team said that the new approach successfully separated Van Gogh’s stylistic signatures from those of 17th‑century painter David Klöcker Ehrenstrahl, an achievement they heralded as demonstrating the technology’s “wider potential.” 

Although the new approach had successes, the team said it is not designed to replace current approaches, including complementary analyses such as the chemical examination of materials. Instead, they said their surface-texture approach should be used as a complementary tool to strengthen authentication, resulting in a multifaceted approach that can reduce risk for collectors, museums, and auction houses alike.

“This approach won’t replace traditional expertise, but it significantly strengthens it.”

The study “Preserving Van Gogh’s Painterly Heritage: Topographical and Fractal Insights in Authentication” was published in Surface Topography Metrology and Properties.

Scientists have often wondered how the brain can take in new experiences without erasing stored memories. However, a new study in Nature now identifies a circuit-level mechanism that may help answer this question—and it may also offer clues for improving artificial intelligence.

Researchers at NYU Langone Health recorded the activity of hundreds of neurons simultaneously across several brain regions in mice. By tracking how signals move from the hippocampus to the neocortex, where long-term memories are kept, they found that a subset of hippocampal neurons appears to participate in routing information between regions in distinct patterns. These cells participate in both incoming and outgoing signaling, but do so using distinct patterns of activity.

Separate Channels Through the Same Cells

The study focused on a series of interconnected brain regions: CA3, which processes rapidly changing information; CA1, which serves as a central hub; and the retrosplenial cortex, which is important for navigation and spatial memory. About one in four CA1 neurons receives most of the signals from CA3. When these same neurons send signals to the retrosplenial cortex, they fire in a different pattern, creating a separate outgoing channel using the same cells.

Rather than using new neurons, the brain separates these channels by changing how the same neurons fire together. The researchers suggest this arrangement may help reduce interference between new learning and more stable cortical memories.

“Our findings help explain how memory can be both moldable and enduring,” said co-lead author Joaquín Gonzalez, PhD, a postdoctoral fellow in the Department of Psychiatry at NYU Grossman School of Medicine. “By changing how the same cells fire together instead of turning on new cells, the brain can keep information organized and protect older memories.”

What Happens During Sleep

The CA1 neurons involved in learning during the day also stay active at night. The researchers found that these cells remain busy during sleep events called sharp-wave ripples, which are bursts of activity the hippocampus uses to replay and strengthen memories from the day.

Since overlapping neurons are recruited during both waking activity and sleep replay, the same circuit elements appear to participate in both learning and consolidation. This theoretically allows the brain to use a single system for both learning and storing memories, without the two processes interfering with each other.

“Our study shows how learning and memory consolidation can coexist in the same network,” said co-lead author Mihály Vöröslakos, MD, PhD. “Our discovery was made possible because for the first time, we were able to record hundreds of individual neurons across all the key regions simultaneously in animals that were moving around naturally.”

Implications for Disease and AI

The system identified in this research may help explain how memory disorders begin. In Alzheimer’s disease, for example, the hippocampal circuits examined here are some of the earliest to deteriorate. These networks are essential for sorting and organizing new experiences.

“Our discovery of a ‘memory switchboard’ deep in the hippocampus may provide clues as to how memory circuits fail in Alzheimer’s disease,” said co-senior author Zhe S. Chen, PhD, a professor in the Departments of Psychiatry and Neuroscience at NYU Grossman School of Medicine.

Artificial intelligence systems have a hard time holding onto what they’ve already learned when faced with new tasks, a problem researchers call catastrophic forgetting. The human brain appears able to update memories without catastrophic forgetting by altering the use of existing neural circuits. By studying how our brains pull this off, scientists hope to design AI that can keep learning new things without forgetting the old.

“By showing how the mammalian brain can safeguard memories during learning, our research may offer a biological blueprint for designing next-generation AI technology that can update itself continuously without overwriting what it has already acquired,” said co-senior author György Buzsáki, MD, PhD, the Biggs Professor of Neuroscience at NYU Grossman School of Medicine.

The researchers plan to investigate whether similar switchboard-like channels exist in other memory circuits. The authors caution that their findings in mice under controlled conditions do not yet allow conclusions about the human brain.

In a University of Kentucky laboratory, three small spacecraft stand-ins slid across low-friction air tracks, nudging and pulling one another without thrusters, propellant, or physical contact.

Instead, they used carefully timed magnetic fields, a technique that could one day help future satellite swarms hold precise formations in space without constantly burning fuel.

The NASA and Air Force-backed study, set to be published in the September 2026 edition of Aerospace Science and Technology,  marks a step toward what researchers call electromagnetic formation flying, a proposed method for controlling the relative positions of satellites using onboard coils rather than conventional propellant-based thrusters.

In the study, researchers demonstrated a decentralized, three-satellite control system that used alternating magnetic field forces to maintain formation with centimeter-level precision, offering a possible pathway for future space telescopes, interferometers, gravity-wave detectors, and other distributed spacecraft missions.

“Spacecraft formation flying can advance a variety of space technologies such as distributed-aperture telescopes, gravity-wave detectors, and interferometers,” researchers write. “One challenge for spacecraft formation flying is that traditional propellant thrusters eventually deplete, and they can contaminate sensitive spacecraft components.”

The study, authored by scientists from the University of Kentucky’s Department of Mechanical and Aerospace Engineering, focuses on a longstanding problem in spacecraft engineering.

Many future missions may not rely on a single large spacecraft, but instead on groups of smaller satellites flying in carefully arranged formations. If those satellites can maintain their spacing and orientation with extreme precision, they could function together like a much larger scientific instrument.

For example, a distributed-aperture telescope could use multiple spacecraft separated by carefully controlled distances to achieve observing capabilities that might be difficult or impossible with a single monolithic telescope.

Similar formation-flying concepts have been proposed for space-based interferometers and additional missions in which the relative positions of spacecraft are central to mission performance.

However, keeping multiple satellites in formation is not easy. Standard spacecraft rely on thrusters, which consume limited propellant. Over time, that fuel runs out, limiting mission duration and maneuverability. Thruster plumes can also contaminate sensitive instruments, a concern on spacecraft carrying delicate optical, scientific, or electromagnetic sensors.

However, electromagnetic formation flying, or EMFF, offers a different possibility. Each spacecraft carries electromagnetic coils. When electric current flows through those coils, they create magnetic fields. Those fields interact with magnetic fields created by nearby spacecraft, producing attractive or repulsive forces that can alter the satellites’ positions relative to one another.

Put simply, the satellites can push or pull on each other using magnetism.

The idea is not entirely new. Previous work has explored electromagnetic formation flying between two spacecraft, including experiments using direct-current-driven coils.

The problem becomes much harder when the formation includes three or more satellites. In that case, every satellite’s magnetic field can interact with the others, creating a web of coupled forces that becomes increasingly difficult to control as the formation grows.

The new study approaches that problem using alternating magnetic field forces, or AMFF. Rather than driving the coils with steady direct current, the researchers use sinusoidal currents at specific frequencies.

The key insight is that two satellites generate a nonzero time-averaged interaction force only when their magnetic moments alternate at the same frequency. If they do not share a frequency, the average force between them is negligible.

That frequency-matching approach effectively allows the system to pair satellites electromagnetically. One pair can interact at one frequency, while another pair interacts at a different frequency.

By adjusting the amplitude of each sinusoidal signal, the satellites can control the strength of the force between each pair without requiring a centralized controller to solve the entire formation’s motion at once.

“Only pairs with a common frequency can generate a nonzero time-averaged intersatellite force, and that force is determined solely by the amplitudes at the common frequency,” researchers write. “The method in this paper is decentralized, which means that each satellite has access to measurements of its position and velocity relative to only its local neighbor satellites.”

Centralized control can work in smaller systems, but it can turn computationally clumsy as satellite formations grow. A scalable system would need each spacecraft to make local decisions based on nearby neighbors, rather than requiring a single controller to calculate every force across the entire formation.

To test the idea, the researchers built a ground-based experimental platform using three custom electromagnetic actuation system units placed on linear air tracks.

The air tracks allowed the units to move with low friction, simulating one-dimensional relative motion between satellites. Each unit included an electromagnetic coil, batteries, power electronics, an Arduino Due microcontroller, wireless communication hardware, and laser range-finding sensors for measuring relative position.

In the three-satellite setup, the center unit was driven by a sum of two sinusoidal currents, while each outer unit was driven by one of those frequencies. This allowed the center unit to interact independently with each outer unit, demonstrating the central premise of frequency-multiplexed magnetic control.

In closed-loop experiments, the three-satellite system achieved formation in less than 30 seconds. The maximum steady-state formation error was less than plus or minus 0.01 meters, or about 0.4 inches. The mean steady-state formation error was less than plus or minus 0.001 meters, or about 0.04 inches.

Those numbers demonstrate that the method did more than produce a magnetic tug in a lab. It allowed multiple units to settle into a desired formation using local feedback and alternating magnetic fields, while avoiding the coupling problem that has limited electromagnetic control for larger formations.

The researchers also compared the experimental results with computer simulations. While the simulations generally matched the observed behavior, the team noted some differences caused by real-world hardware factors, including sensor interference, current saturation, possible misalignment, airflow disturbances along the air tracks, and unmodeled magnetic effects.

Those caveats are important. This was not a spaceflight demonstration, and the system was tested only in one dimension. Real spacecraft would operate in a far more complex environment, where microgravity, radiation, extreme temperature swings, atmospheric drag in low Earth orbit, gravitational forces, Earth’s magnetic field, and equipment restrictions would all matter.

Researchers also note that traditional thrusters may still be needed for orbit maintenance, orbit transfers, or controlling the overall center of mass of a satellite formation.

In essence, this is not a replacement for all spacecraft propulsion. It is better understood as a possible propellantless method for controlling the relative positions of satellites once they are already in orbit and operating as part of a formation.

Still, that limitation does not diminish the possible impact. If electromagnetic formation flying can be scaled and adapted for real spacecraft, it could reduce propellant demands for future distributed missions. That could extend mission lifetimes, reduce contamination hazards to sensitive instruments, and enable spacecraft formations more flexible than today’s architectures.

The research was supported in part by the National Aeronautics and Space Administration (NASA), the National Science Foundation, and the Air Force Office of Scientific Research.

The funding mix reflects the dual scientific and strategic interests in the work. NASA has clear reasons to explore precise formation flying for future space observatories and scientific missions. The Air Force, meanwhile, has an obvious interest in satellite coordination, maneuverability, and resilient distributed space systems.

The study’s most intriguing contribution may be its demonstration that magnetic-field-based satellite control can be both decentralized and scalable.

Rather than treating a multi-satellite formation in a single complicated system that must be controlled from the top down, AMFF allows each satellite to manage interactions with its neighbors using assigned frequencies. That could become increasingly valuable as space missions move toward constellations, swarms, and distributed architectures.

Researchers caution that additional work will be needed to move beyond one-dimensional air-track experiments and toward three-dimensional testing, more realistic sensing and control hardware, and, eventually, on-orbit validation.

Additional coils would be needed for three-dimensional position control, and relative attitude control could require additional actuation frequencies for each interacting satellite pair.

Nevertheless, the laboratory results show that the underlying concept works in a three-body system, which is exactly where the hard part begins.

Two satellites can pull or push on each other relatively easily. Three satellites introduce the coupling problem that makes electromagnetic formation flying difficult. By demonstrating three-satellite control with alternating magnetic fields, the study delivers experimental evidence that the frequency-based solution can work.

For forthcoming space missions, that could be a meaningful step. The next generation of telescopes and orbital instruments may not always be built as single enormous spacecraft. They may be assembled virtually, with multiple satellites flying together as one coordinated machine.

If so, keeping those satellites precisely arranged without wasting propellant could become one of the enabling technologies of future astronomy, Earth observation, and national security space systems.

“This article presented a 3-satellite experimental demonstration of decentralized EMFF using AMFF,” researchers conclude. “The settling time and steady-state formation error achieved in these experiments demonstrate that this approach is most likely capable of meeting requirements for satellite constellation reconfiguration and maintenance, thereby addressing the need for propellant-free formation flying.”

Archaeologists working with the Israeli Antiquities Authority have announced the discovery and excavation of a cave located just outside the town of Fureidis, which has revealed signs of early human presence dating back to between 250,000 and 400,000 years ago.

The team of researchers behind the ongoing excavation said the fortuitous discovery could represent a “time capsule” that has remained sealed for hundreds of thousands of years, offering researchers an unprecedented glimpse into a critical period in human evolution.

Ancient Cave Contains Evidence of Critical Period in Human Evolution

According to a statement emailed to The Debrief, the ancient cave, which lies south of Haifa, near the Zikhron Ya’akov interchange, likely dates back to sometime between 400,000 and 250,000 years before present. The team notes that the range would mean it was sealed since the time of the Acheulo-Yabrudian culture, a period when ancient human ancestors began to display several complex tool-making skills, including various stone blade designs which were in use by hominins until around 300,000 years ago, marking the end of the Lower Paleolithic period.

“The culture we are investigating here was characterized by a variety of advanced methods for producing flint tools, including small sharp handaxes, scrapers, and blades,” explained Dr. Kobi Vardi, head of the Prehistory Branch at the Israel Antiquities Authority and the study’s co-director.

Most archaeologists put the African departure date of the last common ancestor of humans and Neanderthals between 700,000 and 500,000 years ago, and the first genetic interbreeding between the two species around 130,000-1,000,000 years ago. Therefore, finding a sealed cave containing relics from the period between these two critical evolutionary junctures offers the research team an unprecedented opportunity.

“We have been fortunate to excavate a unique site of global importance that has been protected from the ravages of time thanks to the exceptional conditions that existed here,” said team member Professor Ron Shimelmitz of the Zinman Institute of Archaeology and the School of Archaeology and Maritime Cultures at the University of Haifa.

Dr. Vardi agreed, noting that “It is very rare to find a site in such a state of preservation.”

“Every prehistorian who visits the site is absolutely thrilled,” he added.

“The Seeds That Led to the Development of Our Complex Culture”

In that same statement, Prof. Shimelmitz noted that the end of the Lower Paleolithic was a “unique time period” before Neanderthals and modern humans became the dominant hominids of the era and spread across “many regions.”

“Only a handful of sites from this important phase have been uncovered in Israel, and the wider Levant, and most of them are inaccessible for research,” the professor explained, adding that marked changes in human physiology, technology, and social organization “foreshadowed the traits and complex behavioral patterns that developed later and characterize both Neanderthals and modern humans.”

One component that helped facilitate the development of complex culture, highlighted by Prof. Shimelmitz, is the transition from ancient humans living in larger groups. He also emphasized the advent of human ancestors “spending longer periods at the same sites.”

Early excavations have already uncovered evidence of what the researcher termed “intensive use of fire.” These early forays have also found signs of prolonged human activity. Prof Shimelmitz said these signs suggest a “complex and rich camp life.”

Dr Vardi said that the ongoing excavation is uncovering animal bones, including ancient specimens of fallow deer, gazelle, and an ancient variety of horse.

Dr. Vardi also noted that these finds were discovered “alongside evidence of the presence of water,” which he suggests may have made the ancient cave an attractive location for hunter-gatherer groups inhabiting the region at the time.

High Resolution Studies of How Ancient Humans Lived

When discussing the implications of their findings, Prof. Shimelmitz first expressed the team’s appreciation for the financial support and enthusiasm shown by the project’s sponsor, the Ayalon Highways Company, “in enabling us to undertake the excavation.”

As for the scientific value of their initial discoveries and the potential for further insights into this period in human history, the professor noted that findings to date are typically associated with “the development of social cooperation and the transmission of knowledge, as part of the processes of human evolution.”

Dr. Vardi echoed those sentiments, while also noting that the ancient cave’s archaeological value “is no less important” than that of the well-known Nahal Me’arot site from the same evolutionarily critical period.

“(This site) will allow us to study in high resolution how humans lived at that time,” the researcher added.

Given the importance the research team put on the site, which included co-leader Amit Gabbay, the Israel Antiquities Authority and the University of Haifa are already putting forth what they describe as a “large-scale research program that seeks to reconstruct how humans lived, adapted to their environment, and developed new lifestyles and technologies over the course of human evolution.”

Along with heralding the site’s scientific value, the researchers highlighted its cultural importance by declaring their goal to make the site “open and accessible to all: to the residents of Fureidis, students at the nearby school, and anyone interested in the prehistory of the region,” once the formal excavations are completed.

For five years, an elderly woman with advanced Alzheimer’s disease had spoken mostly in single words, needed help walking, and showed little spontaneous interaction with the people around her. Then, roughly 19 hours after receiving a high dose of psilocybin-containing mushrooms, she emerged from a prolonged, deep sleep-like state and began talking about her life.

The striking episode, described in a new case report published in Frontiers in Neuroscience, does not show that psilocybin reverses Alzheimer’s disease. The researchers are careful to stress that this was a single patient, observed in a real-world private clinical setting without brain imaging, formal sleep monitoring, or standardized cognitive testing.

Still, the study’s authors say the case raises the interesting possibility that in late-stage dementia, some functional abilities may indeed remain dormant rather than be completely lost.

“Advanced Alzheimer’s disease is generally regarded as a stage of irreversible functional decline,” researchers write. “This case documents transient multidomain functional improvement in advanced Alzheimer’s disease following psilocybin administration.”

The case involved a Japanese-American woman in her 80s with a 10-year history of Alzheimer’s disease. The patient was described as being in an advanced stage of dementia, with the previous five years being noted for severe decline.

Her speech had become mostly monosyllabic, and she had chronic urinary incontinence, executive dysfunction, dysphagia, dependent mobility, flat affect, prolonged somnolence, and a severe reduction in spontaneous communication.

Her diagnosis had been made clinically about a decade earlier, based on a steadily progressive neurodegenerative course, memory impairment, language reduction, executive dysfunction, and functional decline.

The intervention was a single oral dose of 5 grams of psilocybin-containing mushrooms from the “Enigma” strain. Researchers note that no established psilocybin dosing framework exists for advanced dementia, and the dose was high by almost any comparison.

Recreational users commonly describe 1 to 3 grams of dried Psilocybe cubensis mushrooms as a typical range, while doses around 3.5 grams or more are generally considered strong. A 5-gram dose is often treated as an especially intense experience. However, direct comparisons are imprecise because psilocybin content can vary widely between mushroom species, strains, batches, and even different parts of the same mushroom.

The study also notes that the dose was “relatively high compared with dosing approaches commonly used in modern clinical trials,” which typically use carefully measured amounts of purified psilocybin rather than whole mushrooms.

One month later, after some improvements persisted, the patient underwent a second supervised session using 3 grams.

The first session produced a dramatic acute response. The patient experienced autonomic activation, profuse sweating, suspected hyperthermia, and what the researchers describe as a prolonged deep sleep-like state. Exact temperature measurements were not available.

The study’s timeline shows that the first 12 hours were dominated by autonomic and sleep-like effects. At about 19 hours, the patient spontaneously awakened and produced roughly four hours of autobiographical speech.

By the first day, she showed increased alertness and recognition of family. By the second day, she was independently walking. By days two and three, she was dressing herself and showing spontaneous initiative. Around the same time, her diapers remained dry, including at night.

The improvement in continence was particularly notable to researchers because urinary control depends on more than a single simple reflex. It requires awareness of bodily signals, executive inhibition, and coordination among brain networks affected by dementia. The report states that the patient remained continent one month after the initial session, which was one reason a second session was performed.

During that second session, the patient reportedly remained more verbally expressive and described positive imagery involving surfing with her son on a peaceful island.

Researchers also observed improved facial expressivity, emotional reciprocity, spontaneous humor, and greater agility while walking. At one point during follow-up, the patient spontaneously said, “It is pleasant to come here.”

The study’s broader importance is in what it may suggest about the brain in advanced neurodegenerative disease. Alzheimer’s is usually understood as a progressive condition in which neurons and networks progressively deteriorate, stripping away memory, communication, mobility, and autonomy. By the advanced stage, treatment is largely supportive, and meaningful functional recovery is generally considered unlikely.

Psilocybin, however, is known to transiently alter large-scale brain dynamics via activation of the serotonin 5-HT2A receptor. Researchers point to prior human neuroimaging studies showing changes in default mode network integrity, network segregation, and functional connectivity after psilocybin administration. They also cited preclinical research suggesting psychedelics may promote structural and functional plasticity, including dendritic growth and synaptic remodeling.

That does not mean psilocybin repaired the patient’s Alzheimer’s disease. Instead, researchers suggest a more measured interpretation. The drug may have temporarily altered brain network activity, allowing remaining functional systems to reintegrate or become accessible again, at least for a limited period.

The report does not claim that plaques, tangles, or neurodegeneration were reversed. It also does not show that other patients would experience similar results. Because this was a single case, there was no control group, no placebo comparison, no formal biomarker confirmation, and no standardized cognitive testing to measure the degree of change.

Researchers acknowledge that mixed or alternative neurodegenerative contributions, including vascular components, cannot be fully excluded. Although they found no evidence of acute delirium, intoxication, or another acute neurological diagnosis during the observation period, the case remains observational. Causality cannot be established, and fluctuations in neurodegenerative disease cannot be completely ruled out.

The safety picture is also incomplete. While no severe persistent adverse effects, prolonged agitation, clinically significant cardiovascular instability, persistent psychotic symptoms, delayed neurological deterioration, or delayed medical complications were observed during follow-up, the acute phase included suspected hyperthermia and profuse sweating. In frail elderly patients, especially those with advanced dementia, such responses could carry serious risks.

For that reason, the findings should not be read as a green light for unsupervised psychedelic use in dementia patients. Psilocybin is still a powerful psychoactive compound, and older adults with complex neurological disease may be especially vulnerable to complications.

Ultimately, the value of the report doesn’t lie in providing a treatment recommendation but in documenting an unusual clinical observation that researchers say warrants controlled investigation.

The case also lands amid a flood of scientific interest in psychedelics as tools for studying brain plasticity, perception, memory, and large-scale network dysfunction.

As The Debrief has previously reported, recent brain-imaging work has found that psilocybin can temporarily dissolve familiar brain-network patterns tied to the sense of self, while other studies suggest psychedelics may redirect visual processing toward memory-related regions. Additional research has analyzed how a single dose of psilocybin may produce lasting brain changes, how the compound can reshape neural pathways associated with depression, and how psychedelic effects may be influenced by factors such as exercise, food restriction, and immune signaling.

However, most clinical work with psilocybin has centered on psychiatric conditions such as depression, anxiety, PTSD, and substance use disorders.

More recently, researchers have begun asking whether similar neuromodulatory effects might have relevance for people with mild cognitive impairment or early Alzheimer’s disease.

Published clinical data involving advanced dementia remain extremely limited, which is why the new report is best understood not as evidence of a treatment, but as a provocative case study that may help guide future controlled research.

This recent case does not prove efficacy, but it questions assumptions about what may remain possible in a brain already deeply affected by Alzheimer’s disease.

If future studies find similar effects under supervised conditions, the implications could be significant, not only for dementia care but also regarding understanding how much latent function can persist beneath the outward appearance of severe decline.

“Residual functional capacity may persist in advanced Alzheimer’s disease and may become transiently accessible following psilocybin induced modulation of large-scale brain networks,” researchers conclude. “Systematic investigation is warranted.”

For decades, the possibility of discovering extraterrestrial intelligence has captured the imagination of scientists, sci-fi enthusiasts, filmmakers, and the public alike.

In line with such efforts, the IAA SETI Committee and the uNHIdden Foundation, two separate not-for-profit organizations, have recently released updated rules for evaluating and disclosing detections, and preparing for public preparedness in the event of potential disclosure of extraterrestrial intelligence.

With the release of director Steven Spielberg’s new alien film Disclosure Day, nearly coinciding with the recent release of the government records from the Department of War related to UAP, it seems a growing number of individuals, from the film industry to the science community, have extraterrestrials and “disclosure” on their minds. 

The IAA SETI Committee Rules 

In June 2026, the International Academy of Astronautics (IAA) approved a major update to the protocols governing the evaluation, verification, and communication of evidence related to extraterrestrial intelligence. The revised guidelines were designed to address a modern information environment shaped by social media, artificial intelligence, and the rapid pace of the 24-hour news cycle.

Professor Michael Garrett, Sir Bernard Lovell Chair of Astrophysics, led the international effort to revise the long-standing post-detection protocols used by researchers engaged in the search for extraterrestrial intelligence. The updated guidelines have since been formally ratified by the IAA.

“The information environment we operate in today is vastly more complex than it was in 2010,” said Garrett, Chair of the IAA SETI Committee, in a statement. “In an era of deepfakes, automated misinformation, and instant global connectivity, a single unverified claim could trigger confusion or panic. These new protocols ensure that scientists maintain the highest standards of evidence before making announcements to the world.”

The revised declaration reflects the broader scope of modern SETI and technosignature research. Since the previous guidelines were adopted in 2010, advances in technology have enabled scientists to investigate the entire electromagnetic spectrum, including excess infrared heat signatures that could indicate megastructures, optical laser emissions, and even multi-messenger signals.

The updated framework also addresses modern challenges, including protections for researchers who may face harassment, doxxing, or intense media scrutiny. It further emphasizes the importance of distinguishing verified scientific data from viral rumors, hoaxes, or terrestrial interference.

New Contact Rules at SETI

At the heart of the new guidelines is a familiar scientific principle: extraordinary claims require extraordinary evidence.

Under the revised protocols, no public announcement should be made until a signal or artifact has been rigorously verified by independent organizations using different instruments and methodologies.

“We do not shout ‘alien’ the moment we see a strange blip,” said Garret in a statement. “The scientific method demands we check, check again, and then ask others to check. Only when we have reached a consensus that a signal is credible do we bring it to the world.”

While the protocols explain how to share discovery news, they make one rule clear: no reply should be sent.

“The threshold for ‘extraordinary evidence’ is subjective,” Siemion says. “Because of the vast diversity of modalities in which a technosignature might manifest, it is impossible to state explicitly the criteria that would meet this threshold under all circumstances.”

“In the case of a coherent electromagnetic signal, like a narrowband carrier or a series of laser pulses, an example of ‘extraordinary’ would be if we repeatedly detected the signal at the same location with multiple independent observatories,” Siemion adds.

He also noted that, for a transient signal, compelling evidence might include multiple lines of data indicating that it traveled through interstellar space. Determining whether a phenomenon truly originated from extraterrestrial technology would likely be a lengthy process, with evidence presented, challenged, and reassessed over time.

The declaration reinforces that any response to extraterrestrial intelligence would be a decision for all humanity and should only occur following international consultation, particularly through the United Nations.

With the updated declaration now ratified by the IAA Board, it will be shared with stakeholders, including the United Nations. A formal presentation of the protocols is scheduled for the International Astronautical Congress (IAC) in Türkiye later this year.

“The release of these updated rules and protocols marks an important step in acknowledging both the radically different media landscape that science functions within today, and the vastly expanded efforts in terms of technology and resources being deployed in the search for intelligent life beyond Earth,” said Bill Diamond, President and CEO of the SETI Institute and IAA SETI Committee member. “We applaud Prof Garrett’s leadership in developing these new protocols and the IAA for their ratification.” 

First Contact and Humanity’s Mental Health

Another nonprofit organization has taken a different approach, focusing on the potential psychological and public-health implications of disclosure. The uNHIdden Foundation, whose mission is to support mental health related to Unidentified Anomalous Phenomena (UAP), recently released a preparedness framework addressing the societal impact of a paradigm-shifting discovery.

If governments prepare for natural disasters, pandemics, and other low-probability, high-impact events, should humanity also consider preparing for the possibility of contact with another intelligent civilization?

On June 8, uNHIdden Foundation Founder and Chairman John Priestland, alongside clinical spokesperson Dr. Martin Abbas, launched what they describe as the first public-health preparedness framework focused on disclosure-related scenarios.

Developed by healthcare practitioners, physicians, clinical psychologists, and public-health specialists, “Preparing for Disclosure: A Public Health Framework for Paradigm-Shifting Revelations” examines how society might reduce harm, build resilience, and support individuals processing a profound shift in humanity’s understanding of its place in the universe.

“This report is not a prediction. It is a preparedness exercise,” Priestland says. “Governments prepare for all kinds of low-probability, high-impact events.”

“Our view is that if a paradigm-shifting disclosure were ever to occur, we should at least have thought about the human consequences in advance,” Priestland added. 

The report suggests that certain groups could be more vulnerable to disclosure-related distress, including individuals with pre-existing mental health conditions, those facing socioeconomic hardship, UAP experiencers, highly religious individuals, and some STEM professionals. The authors emphasize that the report neither predicts disclosure nor attempts to judge future discoveries; rather, it argues that preparedness is a prudent response to the possibility of transformative new information.

David Whitehouse, former BBC Science Correspondent, wrote the report’s foreword, arguing that planning is essential should such a discovery ever occur.

The new framework proposes several practical actions to be taken, which include:

• Reducing stigma surrounding anomalous experiences and disclosure-related concerns
• Building public resilience and psychological flexibility
• Developing trusted sources of information and support
• Creating community conversation groups and peer-support networks
• Strengthening mental health preparedness and triage capability
• Encouraging collaboration between healthcare professionals, researchers, government, and civil society

The report argues that stronger community resilience, clearer communication during periods of uncertainty, and improved mental-health support would be critical not only during a disclosure event but during any large-scale societal disruption.

Ultimately, the question remains whether humanity is truly prepared—or whether a globally coordinated framework is still lacking. Voices ranging from the UAP community to figures within the U.S. government have argued that the public is ready. However, only time will tell what the result may be if confirmation of extraterrestrial intelligence were to arrive—and how humanity will collectively respond to the discovery.

A shelter-in-place order issued at the Pentagon on Thursday has now been lifted, officials have confirmed, following what was characterized as a “hazardous materials incident”.

Earlier on Thursday, firefighters arrived at the building, which serves as the headquarters of the United States Department of War, in response to concerns involving air quality at the facility.

“Earlier this morning, Pentagon occupants were notified of a potential air quality issue, prompting immediate precautionary safety measures and evaluation,” said Pentagon spokesman Sean Parnell in a posting on X.

“Subsequent testing confirmed no hazard exists, and normal operations have resumed,” Parnell said. “We express our sincere appreciation to the first responders for their swift actions to ensure the safety of all personnel.”

In an earlier post, Parnell said that the Pentagon houses “sophisticated systems to ensure the safety of the building and its occupants,” which had reportedly detected “an air quality issue necessitating precautionary measures until we determine its significance.”

In response to the unspecified air quality issue, the Department of War observed what Parnell characterized as “standard protection protocols, including a shelter-in-place order for the affected area.”

“Response teams are in place and ready to support building occupants,” the early statement read.

Separate postings on social media from Arlington County Fire and Rescue indicated that its personnel were on the scene supporting hazmat teams while the incident was under investigation.

Presently, it remains unclear what the issue was that prompted the concerns at the Pentagon, where close to 30,000 U.S. military and civilian personnel are employed.

This is a developing story, which may be updated as new information is made available.

Welcome to this edition of The Intelligence Brief… This week, the ongoing conflict between the United States and Iran appears to be edging closer to a broader regional crisis, as both nations exchange new rounds of military strikes amid fading hopes for diplomacy. In our analysis, we’ll be looking at 1) the latest U.S. and Iranian attacks near the Strait of Hormuz and across the Gulf region, 2) President Trump’s escalating rhetoric and warnings of additional military action targeting Iran’s oil infrastructure, 3) the growing humanitarian and economic consequences of the conflict, including disruptions to shipping and concerns over civilian infrastructure, and 4) why analysts increasingly fear that continued escalation could draw the region closer to a wider war with global repercussions.

Quote of the Week

“The strikes are in response to Iran’s unwarranted and continued aggression. U.S. forces remain vigilant, lethal, and ready.”

– U.S. Central Command, June 10, 2026

Ongoing U.S. Conflict with Iran Could Signal a Broader War

This week, a clear end to the ongoing U.S. conflict with Iran still seems remote, as the United States and Iran engaged in another round of military strikes.

Early this morning, strikes exchanged between the nations’ military forces signaled the potential that a dangerous new phase of the conflict may be approaching, after an initial several months of efforts aiming to avoid escalation to a broader regional war.

Among the most recent attacks, several locations near the Strait of Hormuz were targeted, as ongoing warnings by President Trump urged Iranian officials to heed U.S. warnings and bring the conflict to an end.

Latest Attacks in the U.S.-Iran War

In response to the attacks, Iran also launched several strikes on targets linked to U.S. assets that include military facilities in Kuwait and Bahrain. The Iranian strikes prompted air-defense activity throughout the region, along with airspace restrictions that have been temporarily elevated in the Gulf.

Amid the strikes, Iranian officials claimed that all maritime traffic had been closed off from passage through the Strait of Hormuz. However, U.S. officials disputed the claims on Thursday.

The renewed violence follows several strikes confirmed by U.S. Central Command late on Wednesday.

“CENTCOM forces launched strikes on Iranian military surveillance capabilities, communication systems, and air defense sites across Iran. U.S. Marine Corps, Air Force, and Navy assets fired precision munitions on Iranian targets that posed a threat to U.S. forces and international commercial ships transiting regional waters,” read a posting on the official U.S. Central Command X account.

Trump: U.S. Will “Assume Total Control”

Early on Thursday, President Trump also warned about further military action by the United States against Iran.

“The United States will be hitting Iran (Whose Navy, Air Force, Radar, Anti Aircraft, and all other forms of Defense, together with most of its offensive capability, are GONE!), VERY HARD TONIGHT,” President Trump wrote in one of his characteristically bombastic social media postings on Thursday.

Trump also claimed that in “the not too distant future” the U.S. would be capturing Kharg Island, along with other locations that play a key role in the oil infrastructure of the region, with the broader plan to “assume total control of their Oil and Gas Markets, much like we have with Venezuela, which is working out brilliantly for both Venezuela and the United States of America.”

Beyond the typical hyperbolic phrasing, the President’s post on Thursday appeared to indicate locations that could become future targets, although similar ongoing threats have repeatedly been made by Mr. Trump in recent weeks, in an effort to encourage Iranian officials to agree to U.S. demands that aim to curb the country’s nuclear ambitions—a significant goalpost the U.S. has maintained in efforts to end the war.

As Escalations Continue, Broader Problems Emerge

Efforts to bring about a cease-fire agreement have been in the works since April, although Iran’s foreign ministry now says such efforts have been rendered “meaningless” by the continued American strikes.

Firing back, U.S. officials, including Secretary of War Pete Hegseth, have characterized the attacks as being “part of an effort to pressure Tehran into accepting negotiations over its nuclear program” amid broader security concerns the U.S. is attempting to reconcile.

However, more broadly, the conflict is also having a far wider economic and humanitarian impact. Recent U.S. military operations that have targeted vessels suspected of transporting Iranian oil have reportedly struck multiple commercial ships in recent days, with India confirming that three of its citizens were killed aboard one tanker.

“CENTCOM forces have disabled nine non-compliant vessels, redirected 135 ships that complied, and allowed 42 vessels supporting humanitarian aid to pass since initiating the blockade on April 13,” U.S. Central Command wrote in an update on Thursday.

“The blockade is being enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including all Iranian ports on the Arabian Gulf and Gulf of Oman,” the posting added.

Humanitarian and Economic Concerns 

Based on satellite imagery reviewed by analysts, the potential that some of the recent strikes may have damaged drinking-water infrastructure in southern Iran has also been raised, increasing humanitarian concerns.

Financial markets are also reacting to the growing instability. The European Central Bank cited war-related inflation pressures as it raised interest rates, while the World Bank warned that rising energy costs linked to the conflict are slowing global economic growth to its weakest pace since the COVID-19 pandemic.

Overall, as the ongoing military operations by both nations continue, and with few signs of diplomacy on the immediate horizon, concerns continue to mount over whether a broader regional crisis—one the U.S. has hoped to avoid—could now loom nearer than at any time before.

Researchers from the private nuclear fusion energy company Commonwealth Fusion Systems have published a series of papers that they claim confirm that their flagship ARC reactor will produce more usable energy than it consumes if built as designed.

Although the company projects it will deliver the first commercial fusion plants by the early 2030s, other researchers say there are remaining challenges to overcome, and won’t declare the ARC reactor successful until an operational version is constructed to validate the research team’s theoretical predictions.

ARC Fusion Reactor ‘Will Work’ When Built

Scientists have long dreamed of capturing the nuclear fusion reaction that fuels our Sun and using it to generate clean, renewable power. Private fusion firms like CFS have received nearly $10 billion in funding over the last decade alone.

The first laboratory “net-energy” controlled fusion reaction, which fusion scientists call “ignition,” didn’t occur until 2022, when physicists at the US National Ignition Facility in Livermore, California, successfully produced more energy than was used to generate the reaction. Although brief, that moment has fueled speculation that practical fusion energy generation may be right around the corner.

Now, the Commonwealth team, which includes 58 researchers from the company and partner institutes, has published scientific papers outlining the physics of their ARC reactor, including new models that they say account for the “expected behavior” of the superhot plasma at the heart of the design.

Brandon Sorbom, the company’s chief science officer, said that the published works  “confirm that when we build the ARC fusion power plant, it will work”.

Company Claims ARC Will Produce 400 Megawatts of Net Electricity

After nearly a decade of research, CFS, founded in 2018, is currently preparing its prototype for a 2027 demonstration it calls ‘SPARC.’ The company said they expect that trial run, which will demonstrate their technology’s ability to generate more energy than it needs to heat the plasma, will help them fine-tune ARC’s final design.

According to the Commonwealth-led team, ARC will generate more energy than is required to operate the entire facility, including plasma heating, resulting in a true net-positive power-generation facility. This includes producing approximately 400 megawatts of net electricity, which the team noted is enough to power 280,000 average US homes. For comparison, recent census data indicates that Boston, Massachusetts, near the company’s headquarters in Cambridge, has around 271,000 U.S. homes.

Like SPARC, the ARC reactor uses high-temperature superconducting magnets to compress the plasma, which remains suspended by the magnetic fields, preventing it from damaging the chamber walls and terminating any potential fusion reaction. Under this extreme pressure, the nuclei of heavy hydrogen trapped inside the chamber fuse to form helium, the same reaction that takes place inside the Sun.

This fusion reaction results in the release of energy, primarily high-speed neutrons. At its hottest, the donut-shaped ring of plasma reaches seven times the temperature of the Sun.

Critics Applaud Publication While Highlighting Unproven Concepts and Systems

Tony Roulstone, a nuclear engineer at the University of Cambridge, UK, conceded that the CFS team and its collaborating authors are “some of the best in the fusion business” and noted the company’s ARC reactor concept is the result of “good work over many years.” However, Roulstone also warned of the pressure on researchers in privately funded companies to “claim things before the evidence is fully in place.”

David Hammer, a nuclear engineer at Cornell University in Ithaca, New York, said it is a good sign that the team is publishing at a high volume, but also warned that published papers will not guarantee that the built device will work as intended.

Their modeling “has to be proven correct by a fusion reactor that works as designed”, he adds. If the firm can get SPARC operating successfully next year, “it will be an important step forward”, he says.

Hamner also noted that several of the design’s subsystems require further development before it can be declared complete. This includes addressing how plasma will behave in the real world when it becomes unstable versus its modeled behavior, proving out the process for extracting usable energy from the generated heat, and demonstrating that the reactor is robust enough to operate for long periods.

The scientists also noted the challenges in sourcing tritium, the isotopic fuel the reactor requires to operate. Although CFS has outlined its tritium generation process, Hamner noted that the series of published papers neither details the process nor demonstrates its viability.

“There are candidate blanket materials and blanket designs, but there are many engineering person-years needed” to bring a functional ARC-style plant to fruition, he explained.

“We certainly have to build more on top of that foundation laid out in these papers,” a company spokesperson said, adding that they will “be able to produce tritium for operations and for future power plants.”

The following articles were published by the CFS-led team: “Overview of the physics basis for the ARC fusion power plant“; “ARC disruption physics and strategy“; “Performance and Transport in the ARC Tokamak“; “Power and particle exhaust for the ARC fusion power plant“; “ARC Physics Basis-Magnetohydrodynamics.”

Editor’s Note: This article was updated to correct a previous version that described neutrinos, rather than fast-neutrons, in the context of the reporting, and to clarify that the first achievement of a “net-energy” controlled fusion reaction (ignition) occurred in 2022.

The Cozumel dwarf fox, a rare species previously known only from secondhand reports and fossil records, has been discovered alive on Cozumel, a small Caribbean island off the eastern coast of the Yucatán Peninsula.

Researchers published the announcement in Neotropical Biology and Conservation, describing the rescue and identification of the rare dwarf fox before it was released back into the wild. They caution that this rare species, previously believed extinct, faces extreme danger from a host of threats.

The Cozumel Dwarf Fox

As one of the rarest canids on the planet, the species had never before been documented alive by scientists. The Cozumel dwarf fox (Urocyon sp.) is a close relative of the gray fox (Urocyon cinereoargenteus), which is found on the Mexican mainland. After several millennia of isolation on the island—possibly predating Maya settlement—the Cozumel fox underwent insular dwarfism, evolving to only 60–80% the size of its mainland relatives.

Evidence for the animal has been remarkably scarce, and while subfossil remains provided conclusive proof that the species once existed, there had not even been a secondhand report since 2001, leading many researchers to assume it was extinct.

That changed on September 14, 2023, when members of the public reported a disoriented fox along a coastal highway near kilometer marker 29.

Responders from the Fundación de Parques y Museos de Cozumel recovered the animal and cared for it for three days while monitoring its health. On September 17, 2023, the fox was released into the Laguna Columbia State Reserve, where it would be protected from traffic and other hazards.

The sighting marks the first time the Cozumel fox has been formally documented by scientists and recognized as taxonomically distinct.

Cozumel Fox Habitat

Although the sparse evidence of these creatures may not be enough to conclusively map their habitat, the researchers have some idea where the Cozumel fox typically resides.

“Historical sightings have been concentrated around the community of El Cedral and near the entrance of Punta Sur Ecological Park, which is where this photographic record also took place,” lead author Travis Bayer of Pathos Wildlife told The Debrief. “No sightings have ever been observed further north than El Cedral, which leads us to believe that may be the extent of their range on the island, which would also be very concerning due to the already limited space on an island.”

“If their home ranges are restricted to the Southern end of the island, they may have home ranges around 100 km2,” Bayer continued. “If they associate with only wetland/mangrove habitats, the size gets considerably smaller and more concerning for their conservation, as those habitats mainly only occur along the coastline and are at high risk for development for restaurants and resorts.”

Staying Hidden

Given that Cozumel is a popular tourist destination known for its beaches and resorts, it may seem surprising that an animal the size of a fox could remain undetected for so long. Bayer says part of the explanation lies in the island’s difficult terrain and the species’ elusive behavior.

“Cozumel is home to many different terrestrial ecosystems, many of which are not easily accessible either,” Bayer explained. “Habitats like the mangrove forests and wetlands are almost impenetrable to us, but to a fox, easily traversable.”

“Also, not that many people are out there looking for this animal, as the public awareness of it was extremely low, and the scientific investment was limited to one primary publication and a few brief mentions in others,” he added.

Additionally, the combination of grey foxes’ typical elusiveness, their nocturnal habits, and the highway cutting through their habitat being closed at night all combine to make the species easy to miss.

Preserving the Cozumel Fox

“In collaboration with a team of local biologists, led by Rafael Chacón, we have begun developing an emergency conservation action plan for the Cozumel fox aimed at locating remaining individuals, estimating population size, identifying critical habitat, and determining immediate threats,” Bayer said.

Ensuring that the species does not disappear again is now a top priority. Researchers consider the fox critically endangered, with its limited habitat threatened by development, invasive species, and natural disasters.

Several introduced animals also pose significant risks. These include invasive boas released during a 1971 film production that have since spread across the island. Domestic dogs and cats may also threaten the fox through competition, predation, or disease transmission. In addition, predators such as ocelots and margays were introduced as exotic pets before eventually being released into the wild.

“Using thermal drone surveys, large-scale camera trap networks, and other advanced monitoring technologies, we aim to rapidly generate the data needed to guide immediate conservation intervention,” Bayer said. “Simultaneously, we are collecting the evidence necessary to formally describe the animal as a new and distinct species deserving of critically endangered recognition and legal protections.”

“One of the most important takeaways from this research is that species can quietly disappear without the world even realizing they are gone,” Bayer concluded.

“We often think extinction is something dramatic and obvious, but in reality, it can happen gradually and silently, especially for rare species living in remote or understudied habitats.”

The paper, “First Photographic Evidence of an Insular Dwarf Fox (Urocyon sp.) on the Island of Cozumel, Mexico,” appeared in Neotropical Biology and Conservation on May 4, 2026.
