Newly released NASA satellite images reveal the extent of recent wildfire damage on Santa Rosa Island in vivid detail, showcasing the impact of the largest Channel Islands fire on record.

The images, obtained with NASA satellite observation platforms that include the Fire Information for Resource Management System (FIRMS) and the Fire Event Explorer, reveal fire damage to nearly half of the island’s southeastern side.

The fire was initially spotted on May 15, 2026, and containment efforts began as the blaze spread across the island over the following days.

Now, the new NASA imagery is revealing the extent of the damage caused by the historic fire, which officials say came close to endangering one of our nation’s rarest species.

18,000 Acres Scorched on Santa Rosa Island

Current damage estimates indicate that close to one-third of the island was impacted, constituting more than 18,300 acres on the island, which is part of California’s Channel Islands National Park.

Comparisons with past NASA imagery of Santa Rosa Island, made possible with Landsat satellite images, reveal a sharp contrast between once verdant regions of the island, which are now scorched by fire, shown in reddish brown in the more recent images (see below).

Fortunately, Channel Islands National Park officials reported that the fire had been 97 percent contained by May 26, after burning its way through chaparral and grassland covering large portions of the island.

Endangering One of America’s Rarest Species

The Channel Islands serve as a unique and extremely diverse habitat for a range of species of both plants and animals. Among the species threatened during the recent fires were Torrey pines (Pinus torreyana), recognized as our nation’s rarest pine tree, which only grows on Santa Rosa Island and in a preserve in urban San Diego.

Fortunately, most of the island’s Torrey pine forest remains intact, although some damage was reportedly discernible in surveys by firefighters on the island and in drone imagery of the scorched areas.

According to island officials, the fire appears to have burned its way inland at lower intensity, making its way through pine areas that burned ground-dwelling vegetation while leaving the overlying canopy largely unaffected.

Damage from the Largest Channel Island Fire

Park officials say that some smaller areas of forest did sustain significant damage, as conditions in those pockets allowed a greater burn intensity.

Closer to the fire’s northern boundary, Santa Rosa’s cloud forests—the wooded areas comprised mostly of oak and pine growth surrounded by chaparral, whose name is derived from the island fog that sustains them—were successfully preserved by firefighting crews who worked ahead of the fire to cool areas where combustible vegetation grows.

Based on recent local reports, the fire that consumed large portions of Santa Rosa Island’s vegetation is the largest known to have impacted any of the Channel Islands. Fortunately, many of the island’s indigenous trees and other vegetation are resilient enough to withstand fire, since they do not rely on it as part of their growth cycles like many mainland plant species.

Additional information about the fires can be found here, and more imagery of the recent damage has been made available at NASA’s Earth Observatory page.

A massive discovery in northeastern Romania has revealed links to a curious ancient culture from ancient Eastern Europe’s Neolithic and Chalcolithic periods.

Archaeologists say the very large prehistoric structure is associated with the Cucuteni-Trypillia culture, a group recognized as one of the earliest European cultures to construct large dwelling spaces and settlements.

Estimated to be close to 6,000 years old and covering an area of approximately 350 square meters, the discovery of the ancient “mega-structure,” reported in the journal Plos One, occurred at Romania’s Stăuceni-Holm site.

A Mysterious Neolithic Culture

Thousands of years ago, during Europe’s Neolithic and Chalcolithic periods, the Cucuteni-Trypillia culture was among the first to build large settlements, the remains of which have been found in Romania, Moldova, Ukraine, and other parts of Eastern Europe.

Many of the settlements associated with this ancient culture date to as recently as 3500 BCE, although some are thousands of years older. However, crucial context for the lifestyles of those who inhabited these ancient communities is often lacking, as past excavations have revealed little in the way of any graves associated with rulers or other individuals who might have had power or influence in society.

Additionally, most dwellings in even the largest communities associated with the Cucuteni-Trypillia were relatively small, leaving few signs of how their local law and government were organized.

Discovery at Stăuceni-Holm

During fieldwork between 2023 and 2024 at the Stăuceni-Holm site, Romanian and German researchers conducted work over consecutive excavation seasons following initial surveys of the area, which uncovered the existence of massive structures buried beneath the settlement site.

In particular, the team noticed a very large feature located near a foundation ditch that surrounded the archaeological site, as well as areas where the presence of a thick floor of clay was evident. Significantly, unlike most of the small dwellings associated with Cucuteni-Trypillia sites, there was little sign that this structure had been used for daily activities like cooking.

One likely interpretation for the unusual site had been that it was some kind of communal structure, which might have been used for community engagements or other group activities.

Cucuteni-Trypillia Megastructures

Another clue involves the fact that at other Cucuteni-Trypillia settlement sites in Eastern Europe, the remains of similar megastructures, which were seemingly designed as large public buildings, have been found. However, few of these discoveries have undergone significant excavation in the past.

As the research team notes in their study, “at the actual state of the research, it seems unrealistic to consider the function of the building as a storage building or a communal place for consumption of food.”

“Also, there are no clear indications for cult purposes,” the researchers note. However, it is possible that the site could represent something as simple as a house that was built in proportion to the size of a larger family who may have used it, if not “a communal building for decision making or a meeting place for special high-ranking inhabitants reflecting a change towards a more hierarchized organization of the community.”

Lingering Questions About an Ancient Neolithic Marvel

Whatever the case, it seems obvious that these very large structures had some kind of community purpose, which may have been an outgrowth of steadily growing populations at the time. Given their frequent appearances at Cucuteni-Trypillia settlements, it is also obvious that such constructions were important to this culture, whatever their exact purpose had been.

With the discoveries at Stăuceni-Holm, archaeologists have a unique opportunity to add to the existing knowledge about these massive features and new interpretations about their possible uses.

The study, “The mega-structure at Stăuceni-‘Holm’, Botoşani county, Romania and the debate about the governing of Cucuteni-Trypillia-settlements,” appeared in the journal Plos One.

When a Cornell University scientist made an unusual discovery in 2022, she didn’t realize it would reveal one of the largest and oldest of its kind ever documented.

That’s because when entymologist Rachel Fordyce was passing through East Lawn Cemetery while walking to work at the university, and noticed an abundance of bees in the spring air, she couldn’t have guessed that one of the largest networks of these ground-nesting bees ever seen had been hiding quietly beneath her feet, undetected for more than a century.

Fordyce collected a few of the pollinating insects in a jar and brought them back to the university’s entomology lab, where they were soon identified as specimens of Andrena regularis, better known as the “regular mining bee.” As their name entails, these little stinging insects make their homes below ground.

Now, based on Fordyce’s unique discovery, she and her colleagues have learned that one of the oldest and most extensive colonies of these ground-nesting bees ever seen has been thriving for decades under the cemetery. Based on current estimates, there may be more than 5 million of the bees present at the location, which spans around an acre and a half.

By comparison, an aggregation of bees this large exceeds the entire human population of Manhattan Island by more than three times.

A Massive Discovery

Steve Hoge, the lead author of a recent study detailing the discovery, said what Fordyce found is undeniably one of the largest bee networks known to science.

“I’m sure there are other large bee aggregations that exist around the world that we just haven’t identified,” Hoge said, “but in terms of what is in the literature, this is one of the largest.”

That isn’t to say that there hadn’t been knowledge of this species in the area already. Based on historical information the researchers uncovered, evidence of the presence of regular mining bees in East Lawn Cemetery had been documented at least as early as the beginning of the 1900s.

Although we normally associate cemeteries with death, they can actually serve as important life support systems by providing habitats for several species.

Older cemeteries—especially those in large cities—can also provide a potentially crucial refuge for not just insects, but also plants, birds, and even mammals. Among the reasons for this are that the land apportioned for cemeteries sees little disturbance over time, and in the case of insects like bees, it is free of the kinds of pesticides that can endanger them.

New Clues to the Mysteries of Bees

Although bees and other ground-dwelling insects are ubiquitous, Hoge was surprised to find how little information was available in the literature about A. regularis.

Based on one of the most detailed scientific references he found, which dates to the late 1970s, females of the species are largely credited with burrowing their nests, where eggs are deposited in chambers alongside pollen and nectar.

Their appearance in large numbers in the spring, as Fordyce noticed in 2022, is partly because the species overwinters as adults, which Hoge says “is relatively rare” for pollinators.

Another key factor regarding East Lawn Cemetery’s massive population is its proximity to Cornell Orchards, which is located less than half a mile away.

The study was carried out using small mesh emergence traps, which researchers can use to funnel insects into glass containers as they leave their underground nests. From late March until mid-May 2023, ten of these traps were used throughout the cemetery to collect more than 3,200 insects. Other species the research team captured along with A. regularis were beetles and varieties of flies, although they say bees “dominated” the samples they obtained.

The total estimated bee population the team calculated indicated an average of 5.5 million bees, although as many as 8 million of the pollinators could be hidden below the cemetery.

Citizen Scientists Becoming Involved

Other aspects of the bees’ lives, which include differences in the emergence patterns between males and females, and the phenomenon known as brood parasitism, where nomad bees (Nomada imbricata) occasionally enter the nests of A. regularis colonies and lay their own eggs inside their brood cells. Upon hatching, these larval interlopers kill the host larvae and plunder the pollen and nectar stores within the mining bee nests.

As a means of locating and protecting these beneficial pollinators and their aggregations, the research team has now appealed to citizen scientists for help with locating and reporting similar nesting sites.

“These populations are huge, and they need protection,” says Bryan Danforth, professor of entomology in Cornell’s College of Agriculture and Life Sciences.

“If we don’t preserve nest sites, and someone paves over them, we could lose in an instant 5.5 million bees that are important pollinators,” Danforth says.

Danforth and the team’s recent study, “Emergence dynamics and host-parasite associations in a large aggregation of Andrena regularis (Hymenoptera: Apoidea: Andrenidae),” appeared in the journal Apidologie.

Residents of New England were startled over the weekend as a loud quaking boom shook the northeast, while many observers spotted a bright fireball streaking through the skies over the U.S. and Canada.

Now, NASA has confirmed that the energy released as a meteor exploded in the northeastern skies on May 30, 2026, was roughly equivalent to 230 tons of TNT. The resulting blast was also so bright that it registered in satellite imagery normally used to detect powerful lightning bolts.

Shortly after the incident, NASA took to social media, reporting that the GOES-19 satellite had detected a bright fireball at 2:06 p.m. EDT that coincided with reports of loud booms.

“The meteor appears to have fragmented at an altitude of 40 miles over northeast MA and southeast NH,” the NASA statement read, adding that at the time, the energy released as the object tore apart while streaking through the atmosphere was approximately the “equivalent to about 300 tons of TNT, which accounts for the loud noise.”

In the video above, provided by NOAA, imagery from the GOES East (GOES-19) satellite revealed the meteor, which the satellite’s sensors registered as a lightning bolt. The meteor appears approximately one second into the looped imagery above, seen as a bluish-white flash to the right of the center of the frame.

In a subsequent update issued on Monday, NASA officials have now revealed new details about the incident, confirming the object’s size, mass, and the approximate speed as it passed above the Earth.

“The meteor was about 5 feet (1.6 meters) in diameter with a mass of 5.6 metric tons and entered Earth’s atmosphere at roughly 42,000 mph,” NASA officials wrote in Monday’s statement. “The meteor traveled through the atmosphere from northwest to southeast for 26 miles before breaking up at an altitude of 31 miles and producing a meteorite fall into Cape Cod Bay.”

The NASA update also slightly downgraded the power of the blast that the exploding object produced.

“Based on the latest data, the energy released at breakup is estimated to be equivalent to about 230 tons of TNT,” NASA’s statement on Monday noted.

Fortunately, there were no injuries or damage to property or infrastructure resulting from the May 30 incident. However, some area residents who were present at the time of the explosion reported feeling buildings shaking on Saturday afternoon.

In a statement provided by the agency from its NASA Space Alerts account on X, which periodically issues notifications on “cosmic activity in near-Earth space including solar events, asteroids, comets, and meteors,” the agency noted that objects like the one observed over the northeast, while capable of producing loud noise, are generally not viewed as being potentially dangerous.

“NASA’s planetary defense network watches the skies for objects of all sizes – and specifically is tasked with finding objects 140 meters and larger which can cause widespread damage,” the notification read.

“Meteoroids, like this one over New England, are much much smaller,” the statement added, calling them “almost impossible to track in space” and adding that “they do not survive passage through our atmosphere intact and do not pose a hazard.”

Fortunately, larger and potentially more dangerous space objects aren’t as “impossible” for NASA to track. Presently, the American space agency and its international partners are tracking more than 40,000 larger near-Earth objects (NEOs) and are frequently discovering new ones as part of their broader planetary defense objectives.

The explosion heard over the northeast on Saturday marked only the latest in a series of similar incidents that have occurred in the early part of 2026.

On March 21, a meteor crashed through the roof of a Texas home, causing minor damage, although no injuries were reported. Also in March, a meteor that exploded above Ohio on Saint Patrick’s Day similarly alarmed residents, one of whom described the sound to The Debrief as having resembled “a nuclear explosion” due to its volume and duration.

NASA provides additional information about meteor reentries and their effects at its Fireballs FAQ page, which can be found here.

For just an hour in late 2019, a cosmic mystery revealed itself to astronomers in an unprecedented way: by bending the light of a star as it passed between Earth and a distant galaxy.

The odd event unfolded on the evening of December 18, 2019, as a star in the Large Magellanic Cloud suddenly—and only for a short time—appeared to become brighter. But what could cause an ordinary star to randomly illuminate in this way, becoming a cosmic beacon for only an hour?

Astronomers considered a few possibilities, the most likely being that some kind of object—and one possessing a significant amount of mass—passed in front of the star, warping its light toward Earth through gravitational microlensing.

Now, the curious object that captured the star’s light for an hour in 2019 has been given a name: Phoebe. Unraveling the mystery as to what it actually was constitutes an intriguing question for astronomers, one which has now been tackled in a recent paper.

Gravitational Microlensing

One of the most fascinating phenomena in modern astrophysics is an effect predicted by Einstein, where gravity itself can act like a lens. The result can often produce beautiful and mysterious cosmic features, which include what astronomers call “Einstein rings” as light from a distant object is warped around a nearer, extremely massive object, taking on a circular or ring-like shape.

A similar effect, known as an “Einstein cross,” produced the even more unusual appearance of multiple objects surrounding a nearer, massive source of lensing.

Under most conditions, these objects remain static and can be observed indefinitely. However, in 2019, something very different happened. The light from the star observed in the Large Magellanic Cloud was apparently only subjected to lensing for a short amount of time, meaning that whatever the massive “Phoebe” object was that caused the effect had been in transit.

Possible Explanations

The discovery was revealed as astronomers from Swinburne University in Melbourne spotted Phoebe in the data for a high cadence survey being conducted of the satellite galaxy in question. Now, in a new paper, they propose three possibilities for the mystery object.

One involves a free-floating planet somewhere within the Milky Way, something astronomers also occasionally call “rogue planets.” These cosmic loners come to exist when a planet is ejected from its host system, leaving them to drift through space as lonely planetary wanderers.

Another possibility the team proposes is that the same thing could be going on within the Large Magellanic Cloud itself: a rogue planet originating from that galaxy might have passed in front of the star. If this were ever confirmed, it would mark a notable first, as it would confirm the only extragalactic microlensing planet ever observed by astronomers.

However, a third possibility involves something more unusual: the presence of a primordial black hole, whose origins could go all the way back to the moments immediately after the Big Bang.

Searching for Clues

A major clue to solving the mystery involves the fact that the event took place over just one hour. Given the short duration, it seems most likely that the object was relatively small and therefore able to complete its transit in a short amount of time.

Such a short duration presents challenges for astronomers, since it rests at the threshold of detectability, although the team was able to extract enough information that they could calculate the rough mass of the object, which they believe to have been roughly four times the mass of the moon.

So whatever the object was, it was probably also too small to have been a planet, and also far too small for a normal black hole—the kind produced as a result of stellar collapse—to qualify.

The same couldn’t be said for a primordial black hole, however. Based on additional calculations, the team was also able to demonstrate that Phoebe most likely represents a dark matter object, by around five orders of magnitude greater than other possibilities they looked at.

Overall, this reveals that Phoebe could potentially be one of the oldest objects astronomers have ever spotted, since if its identity as a primordial black hole holds, that would mean its origins go all the way back to the genesis of our universe as we know it.

So based on the team’s work, a star’s mysterious brightening for just one hour in late 2019 might have been even more than an unusual astronomical one-off event: it may have offered us a glimpse at one of the oldest objects in the universe.

The team’s paper, “AMPM II. A Lunar-Mass Primordial Black Hole Microlensing Candidate in the Milky Way Halo,” appeared on the preprint server arXiv.org on May 19, 2026.

Is Anti-Tech Extremism on the Rise?

This week, a concerning new report based on Freedom of Information Act Requests and other data has revealed new concerns about what U.S. officials characterize as “anti-technology extremists.”

The concerns were reportedly detailed in more than 1,000 pages of documents originating from the FBI, the U.S. Department of Homeland Security (DHS), and other federal sources, as well as fusion centers—hubs for the sharing of intelligence between federal and state law enforcement agencies—located across the country.

The apparent shift among U.S. officials regarding this alleged concern was first reported by Wired this week, according to records it obtained, marking a growing concern over the potential unforeseen consequences of the proliferation of machine intelligence across various sectors of industry and society.

Military Techno-Industrial Complexities

U.S. federal law enforcement agencies have reportedly expressed concerns about the possibility of anti-AI extremism and potential threats to national security, according to the investigation published by Wired this week.

Citing one report attributed to the New York Intelligence and Counterterrorism Bureau, “The chaotic atmosphere that may result from emergent AI technology in the next five years may fuel large-scale protests that devolve into civil unrest and anti-tech violent extremist activity, especially in large urban areas such as New York City.”

At the heart of much of the issue is the rise of AI implementation under the current U.S. administration, where new efforts to implement machine intelligence in America’s military, as well as within the business sector, are being urged by President Trump.

Experts fear that such factors could become flashpoints amid political tensions, which could help to foment public opposition to AI and its use in government.

For now, the U.S. administration has engaged in little regulation of the technology, and late last year, one Trump executive order specifically focused on removing AI regulations imposed by some states related to security concerns. Trump similarly postponed signing an order that allowed the U.S. federal government early access to new AI models for a period of 90 days before their public release.

Domestic Troubles

Another key factor related to the renewed concerns among U.S. officials involves the recent National Security Presidential Memorandum 7, which outlines new categories associated with threats from groups the administration identifies as holding “anti-Americanism” and/or “anti-capitalist” views.

Such views were reflected in the public version of a new U.S. counterterrorism strategy released earlier this month, which also identifies violent left-wing extremists and anti-fascist groups amid narco-terrorists and terrorists linked to religious extremism.

Amid such shifts regarding ideologies and groups the U.S. identifies as potential security concerns, the notion that anti-AI extremism might be similarly viewed as a focus of law enforcement agencies holds real potential, especially with growing resistance to AI already apparent in various areas of society.

Such concerns stem from a range of issues, including fears related to workforce displacement as more jobs are handled by AI systems, as well as worries about the misuse of AI, or even the potential that it could one day represent an unintended threat to humanity.

Real World Examples?

According to the Wired investigation revealed this week, real-world examples may already be appearing. One involves how the New York Intelligence and Counterterrorism Bureau points to the arrest and trial of Ziz LaSota, a cult group leader who allegedly has radical views regarding AI.

Other examples include fusion centers throughout the nation that are reportedly monitoring various public meetings and events where individuals have expressed skepticism or concern over the proliferation of AI data centers.

The original report by Wired has been made freely available due to its basis on information obtained using FOIA requests, and can be read here.

A major biological surprise has emerged from the heart of the mysterious Himalayas, according to scientists who made the unexpected discovery.

The vast mountain system in southern Asia is renowned for more than just its height—it is also one of our planet’s most under-explored regions in terms of its biological diversity. Currently, scientists estimate that there may be as many as several thousand unknown species awaiting discovery, with an average of more than 30 being discovered each year.

However, a remarkable recent discovery by scientists has revealed not one, but five different previously unknown Himalayan species—all of which were hiding in plain sight.

One of the most venomous snakes known to the region, the Himalayan pit viper, has now been revealed to be an entire species group, rather than just a single species previously recognized in two varieties.

The addition of three previously unknown species to the group now reveals a major biological surprise that has remained unknown to herpetologists—scientists who specialize in the study of snakes—for more than 160 years.

Five Times the Venomous Viper

Although the Himalayan mountains are probably the last place one would expect one of Asia’s most venomous snakes to reside, the Himalayan pit viper has been known to scientists since 1864. Since its discovery, scientists had long assumed it was a single species of snake that was fairly ubiquitous throughout the mountainous region.

The surprise discovery that this species actually represents five distinct varieties of snake, revealed in a recent study that appeared in the open-access journal ZooKeys, upends that presumption.

The study relied on skeletal studies of existing specimens, supplemented by modern genetic analysis. These combined approaches, along with a fresh analysis of the physical traits of the venomous Himalayan reptiles in their natural environment, now reveal a much deeper and more distinctive evolutionary story about these dangerous Asian reptiles.

Hidden in Plain Sight

The recent findings now confirm three species that are entirely new to science, which primarily reside in portions of the mountain range in Pakistan and Nepal, each possessing slightly different skeletal and physical features.

Daniel Jablonski, a researcher with Comenius University Bratislava and an expert who has been studying species in this region for years, says it was no surprise that new species would have been found in the Himalayas.

“These mountain systems still harbor overlooked vertebrate diversity and hold important clues to the biogeography of Asia,” Jablonski said in a statement. What was surprising, however, was that three of these species had been hiding in plain sight, remaining misidentified as known varieties of Himalayan pit vipers.

“By combining modern field sampling with data from historical museum specimens, we uncovered evolutionary lineages that had remained hidden for more than a century after the original description of the Himalayan pit viper,” Jablonski adds.

Museum Discoveries

Based on specimens already being kept in museums—some of them more than a century old—Jablonski and his colleagues were able to reveal the deeper genetic diversity of these snakes, thanks to reexaminations that included the original type specimen of the species collected in the 19th century.

Sylvia Hofmann, a researcher with the Museum Koenig as part of the Leibniz Institute for the Analysis of Biodiversity Change, says that discoveries that significantly advance our knowledge of the natural world often begin with specimens that already exist in museums.

“Museum specimens are not just records of the past. They are active research tools and essential infrastructure for future science,” she says.

Hofman has spent the past two decades working in the Himalayas and the Tibetan Plateau, and is well aware of the kinds of discoveries this rugged part of the world features.

“Some of the key evidence had been sitting in museum collections for more than a hundred years. We just didn’t have the tools to recognize it,” Hofman said in a recent statement. “As analytical methods continue to improve, the scientific value of these collections will only grow and reveal biodiversity we didn’t even know was there.”

More Surprises Could Await

According to the research team behind the discovery, many more discoveries await scientists who are willing to go seeking the evidence.

“Pakistan’s high mountains are still full of biological surprises,” Rafaqat Masroor, a leading herpetologist with the Pakistan Museum of Natural History, said in a statement.

“This finding highlights how little we still know about a region long shaped by socio-political instability,” Masroor added.

Fundamentally, the discovery is significant not just in terms of expanding our knowledge of the natural world, but also because it has implications for conservation efforts in the region.

“Each of the newly recognized species seems to occupy a relatively restricted range in fragile mountain environments, highlighting new ecological and evolutionary questions,” Jablonski said.

The team’s paper, “Integrative taxonomy reveals previously undescribed diversity within the Gloydius himalayanus complex (Squamata, Viperidae, Crotalinae) from the Himalaya and Hindu Kush,” appeared in the journal ZooKeys.

Physicists with the ATLAS Collaboration report the first observation of an exotic new particle, which could help deepen our understanding of the mysteries surrounding one of the four fundamental forces in physics.

The achievement was revealed recently at the Large Hadron Collider Physics conference, where researchers said the new particle appeared to display properties strongly suggestive of the Bc*+ meson.

This unique particle is theorized to be a variation of the Bc+ meson, albeit in a more excited form. The observation now brings the total number of new particle discoveries by CERN’s Large Hadron Collider (LHC) to 82.

A New Particle Emerges

Both the newly discovered Bc*+ meson is part of the broader family of Bc+ meson particles, which consist of an antiquark at their bottom and an up (B⁺. ), down (B⁰. ), strange (B⁰. ₛ) or charm quark (B⁺. c) in their top position.

Such particles were once relegated only to theory since the top quark’s short lifetime would seemingly prevent their physical existence. However, confirmation of the Bc*+ meson, which possesses a charm quark and a bottom antiquark, could help move physicists closer to understanding the mysterious strong force, which, along with the weak force, electromagnetism, and gravity, constitutes the four fundamental forces of the Standard Model of particle physics.

Even after many decades, physicists remain in the dark about certain characteristics of the strong force, such as how it can bind quarks together.

Particles that consist of heavy quarks offer physicists a promising means of testing a range of theories about how the strong force functions, and Bc+ mesons are of special significance in such efforts since they provide a pathway for physicists to unravel clues to what, precisely, holds these particles together.

The Newest Member of the Bc+ Family

According to a recent CERN news release, the new particle was generated during extremely high-energy proton-proton collisions at the LHC.

Before decaying into a Bc+ meson and a photon, the new particle was successfully observed, albeit briefly. According to CERN researchers, a detection of the photon coinciding with the properties of decay associated with the Bc+ meson could offer a long-sought “smoking gun” that would demonstrate the Bc*+ meson.

A key issue physicists currently face involves the particle’s mass: it is anticipated that the mass of this particle would clock in at only a tiny bit larger than the Bc+ meson. Because of this, the photon that should emanate from the decay at the time of the particle’s generation would possess so small an amount of energy that it would likely be indiscernible using any conventional methods.

To overcome this, researchers tried a different approach: They decided to look within the ATLAS tracking detector for the photon converting into an electron-positron pair. In theory, the ephemeral, closely spaced charged particle “tracks” would be produced as a result of the primary proton-proton collision.

“These tracks can have transverse momenta as low as 100 MeV – significantly lower than those typically studied in ATLAS analyses,” according to the recent statement. “This required researchers to deploy a dedicated track-reconstruction procedure to be able to successfully reconstruct the photons and thus identify the Bc*+ meson.”

Toward a Better Understanding of the Strong Nuclear Force

According to researchers, the differences measured between the masses of the Bc*+ meson and the Bc+ meson are 64.5 ± 1.4 MeV, which falls well within the expected ranges based on current theoretical models.

While falling within expected ranges, ATLAS Collaboration researchers did note that the observed differences differed slightly from current high-precision calculations for these values. Still, the discovery offers more than enough data to assist in broadening current theories and eventually allow physicists to glean new insights into the mysterious strong force.

“This result provides valuable new input for theoretical models describing the masses of particles containing the heavier quarks and will help to improve the understanding of the strong nuclear force,” the researchers said.

The ATLAS Collaboration’s findings were reported in a new paper, “Observation of a B∗+c meson with the ATLAS detector,” which appeared on the preprint arXiv.org server.

Archaeologists in Croatia have made an unusual discovery at an ancient ritual site along the country’s southern coast.

Within Crno Jezero cave, an 80-foot-long cavern that extends 300 feet beneath the Pelješac peninsula in southern Dalmatia, just north of Dubrovnik, archaeologists have located an unusual relic dated to the 4th century.

The discovery, according to Croatia Week, is a terracotta head featuring a Greek theater mask, which it is believed would have likely been featured as an ornament once mounted on a wall.

In ancient Greece, theater masks were items that actors wore while performing a range of stage productions that included tragedies, comedies, and other kinds of plays.

These masks were normally crafted from very lightweight materials like wood, cork, or leather. Some of the masks were designed as full-face helmets worn by actors, which helped to amplify their voices and project their exaggerated emotions in ancient open-air amphitheaters.

The discovery of the artifact follows a similar discovery associated with ancient Greece previously made at the cave, involving a possible Greek deity that was unearthed last year.

The discoveries may point to the cave’s use as a ritual site over the centuries, during periods where the cave likely served as a sanctuary from the Bronze Age up through the Middle Ages, according to Domagoj Perkić of the Dubrovnik Museums.

“Whether Dionysus, or his Illyrian counterpart, can be connected with the wine vessels and the mask found in the cave remains open to interpretation,” Perkić said in a statement.

Perkić says that there have been other discoveries that may link the site to the periods during which it served as a sanctuary, which include high-quality Greek pottery.

Items that include Greek amphoras and bowls, as well as drinking vessels such as kantharoi, have been uncovered close to the opening of the cave.

“Most of the sanctuary-related finds were discovered in the entrance and side sections of the cave, which had remained hidden and buried until excavations,” Perkić says.

Additional archaeological evidence uncovered at the cave suggests some pottery was crafted on-site using local materials, possibly as votive offerings.

Researchers say that a discovery in remote northern Australia has revealed that a species thought to have been driven to extinction more than half a century ago has been rediscovered in the wild.

The discovery was made possible by a chance photograph uploaded to the citizen science platform iNaturalist, which came to the attention of researchers.

Now, scientists have confirmed that Ptilotus senarius, a delicate shrub that grows in some of the outback’s most sparsely populated regions and possesses a distinctive purple-pink flower, has been rediscovered in rugged terrain near the Gulf of Carpentaria in Queensland.

The species hasn’t been documented by naturalists in the wild since 1967 and was long thought to have gone extinct.

An Australian Shrub Springs Back from Extinction

The remarkable discovery initially surfaced when Aaron Bean, a professional horticulturalist, noticed the plant while working as part of a bird banding operation in a rugged portion of Australia’s northern outback. Intrigued by the colorful flower, Bean took photographs, which he later uploaded to iNaturalist, a popular website and app that allows users around the world to map and share observations of biodiversity.

Sometime later, Bean’s images on the platform eventually came to the attention of Anthony Bean, a botanist at the Queensland Herbarium who, ironically, shares the last name of the horticulturalist who made the initial discovery.

Their common name was perhaps only one of the many serendipitous circumstances related to the discovery, since the original images finding their way through millions of observations shared on the platform and coming to the attention of a Queensland Herbarium botanist was remarkable enough—add to that the fact that, in another surprising twist, Anthony Bean had formally described Ptilotus senarius himself roughly a decade earlier.

“It was very serendipitous,” said Thomas Mesaglio of the UNSW School of Biological, Earth and Environmental Sciences, who penned a recent paper documenting the discovery that appeared in the Australian Journal of Botany.

“Aaron Bean is an avid iNaturalist user who opportunistically took some photos of a few plants that were interesting on the property,” Mesaglio noted. Following the imagery that Bean obtained and its coming to the attention of the broader botanical community, researchers were dispatched to the property where the photos were captured, and, with the assistance of the landowners, the collection and confirmation of a specimen proved beyond any doubt that Ptilotus senarius survives.

A Breakthrough for Citizen Science

The rediscovery of Ptilotus senarius is not only a remarkable event for conservation efforts; it also highlights the growing importance of citizen science in biodiversity research.

With the availability of platforms like iNaturalist, members of the public with little more than a keen interest in the natural world can contribute valuable observations that often help advance science in meaningful ways.

In cases like this one, it can even lead to rediscoveries of species thought extinct or, in some instances, to the identification of entirely new species.

Thanks to such discoveries, several programs, including New South Wales’ Land Libraries initiative, have begun ramping up efforts to encourage landowners to document species on their properties and contribute observations to citizen science databases.

Among the most important pieces of information that citizen scientists can contribute are multiple photographs from various angles whenever possible. With regard to plants, being able to identify bark, stems, leaves, and other key features, as well as the surrounding habitat, can greatly help with accurate species identification.

Additional information that can assist with such identifications includes photos of soil conditions, nearby vegetation, scents the vegetation may produce, and information about local pollinators.

“The more information you can provide and the more context you can provide, the more potential uses that record will have in the future,” Mesaglio said.

Mesaglio’s paper, co-authored with Anthony R. Bean and Aaron Bean, is titled “Rediscovery of a presumed extinct plant species, Ptilotus senarius (Amaranthaceae), through iNaturalist,” and appeared in the Australian Journal of Botany.

At the height of China’s ancient Ming dynasty, ancient surgeons appear to have possessed early knowledge of a surprisingly advanced medical application, according to new findings.

Researchers at Northwestern University have revealed that surgeons in ancient China were using aconitine, a poison derived from monkshood and similar toxic plants, for medical applications. The research offers the first evidence of its controlled use, revealed through analysis that discovered residue of the poisonous substance on surgical tools dating to between 1348 and 1411 CE.

Discovered on tweezers and surgical scissors recovered from an ancient tomb in Jiangyin, China, the researchers used microscopic analysis to reveal this highly sophisticated knowledge displayed by Ming dynasty surgeons. The findings were reported in the journal Antiquity.

Clues from Residues

Archaeologists can discern a remarkable amount of information about the ancient world from faint residues left behind on ancient objects.

From blood-protein analysis that reveals the kinds of megafauna hunted by America’s Paleoindian hunters, to environmental DNA that is revealing new genetic information about the world of our ancient archaic cousins, the Neanderthals, microscopic traces from long ago can reveal a surprising amount of information about life in ancient times.

Now, the microscopic study of 700-year-old residues left on surgical tools from China’s Ming dynasty is revealing something equally remarkable: the advanced medical knowledge of ancient Chinese surgeons.

Advanced Ancient Surgical Practices

Applying conventional microscopic analysis can be difficult in some cases, and that was a primary challenge for Northwestern researchers studying the Ming dynasty artifacts retrieved from a tomb near Jiangyin, located along the Yangtze River in China’s Jiangsu province.

To obtain the minimum amounts required for positive residue analysis and identification, the Northwestern team employed an innovative nondestructive technique called stimulated Raman scattering (SRS), a variety of microscopic imaging that is used in modern applications to help identify certain materials and their components.

Significantly, SRS microscopic imaging can also be used to overcome the problem of obtaining minimal sample requirements, according to Northwest University Professor Congcang Zhao, who says the process overcomes “the key challenges in residue research of minimal sample availability and the need to preserve archaeological material.

Zhao, a co-author of the recent research, and his colleagues were able to rely on this process to detect trace amounts of the toxic substance derived from the poisonous flowering plant Aconitum, which is also known as monkshood, wolfsbane, and by other names.

Known for its extreme toxicity, ancient Chinese medical practitioners had somehow managed to discover that when detoxified using processes that included boiling the plant in vinegar or using mung beans, aconitine could be used to produce a powder that possesses anesthetic properties.

The detoxified aconitine powder, in turn, could be used to reduce pain during surgeries, and evidence for the production of such anesthetic powders are known from ancient Chinese medical literature.

However, evidence for its direct use in surgery had never been observed until now.

“Six centuries ago, a Ming Dynasty surgeon performed an operation with a pair of iron scissors and tweezers, and today we have read the traces of anaesthetic medicine left on those instruments using a beam of laser light,” Zhao explained in a statement.

Discovery of an Ancient Anesthetic

According to the new research, which complements information found in ancient texts, aconitine powder was likely applied topically to an area before incisions were made. This process would have required very careful administration, since some of the substance’s toxic qualities would have remained in the powder ancient Chinese medicinal practitioners produced.

Zhao says that when viewed alongside ancient medical texts from the Ming Dynasty, the study he and his colleagues have produced “confirms that Aconitum was employed as a topical anaesthetic, safely and precisely applied during surgical procedures.”

“Ming physicians used iron surgical instruments and controlled the toxicity of aconitine

through topical application, compound prescriptions and strict procedural controls,” Zhao adds, “demonstrating a practical ability to balance drug potency with patient safety.”

The new research reveals not only that such surprisingly advanced medical applications existed in ancient China, but also that the surgeons who used them understood the necessity for employing them safely, in order to mitigate unwanted side effects.

The result, Zhao says, is a new window towards understanding the precocious surgical practices of 14th century Ming Dynasty medical practitioners.

“This is the first time humanity has found direct chemical evidence of anaesthetics on ancient surgical tools, proving that our ancestors already knew how to safely alleviate patients’ pain with highly toxic herbs,” Zhao says.

The recent study, “Surgical anaesthesia in Ming China: scientific analysis of aconitine residues on medical instruments,” was published in the journal Antiquity.

In the tenebrous furthest corners of the World Wide Web, an unusual new kind of internet tourism has manifested, and now scholars are trying to understand why.

Made in the likeness of empty spaces that resemble unfurnished rooms, desolate alleys, undecorated corridors, or vacant voids within concrete walls, these out-of-the-way online environments, known as “backrooms,” are becoming increasingly popular online destinations.

These “Backrooms” are the collective product of online communities “legend trippers”—users whose shared experiences through stories, journaling, videos, and imagery, or other forms of creative expression—invite weary internet travelers in for an unusual online experience that serves as a web-based corollary for traditional “dark tourism.”

Now, in new research by co-authors Dr. Sophie James and Professor James Cronin from Lancaster University Management School (LUMS), these liminal areas of the web are being revealed as a unique—and at times unsettling—new kind of online tourism, accessible through immersive digital environments.

A View from the Backroom

“Our research shows that people are increasingly drawn to intense emotional experiences in spaces that are not physically real, but still feel vivid and meaningful,” Dr. James recently explained.

A lecturer in LUMS’s Department of Marketing, James, and her co-author characterize the Backroom phenomenon as what they call “para-terrestrial dark tourism,” a term they use to describe online encounters with non-existent environments that are evocative of being “place-like,” but which exist someplace well outside of any conventional geography.

“The Backrooms demonstrate how digital culture is transforming what it means to explore and to feel present somewhere, while also raising broader questions about how people engage with risk, ambiguity, and the unknown in digitally mediated worlds,” James says.

Backrooms on the Silver Screen

The Backroom phenomenon is likely to garner even more attention, James argues, since it has become the focus of a forthcoming film produced by A24, the American independent film company best known for their distribution of arthouse and cult cinema features, which often feature odd, ethereal, and unsettling themes.

“Our research is especially timely, given the growing cultural attention around the upcoming Backrooms film, produced by A24, which reflects how these once niche internet imaginaries are moving into the mainstream,” James says.

Dr. James and Professor Cronin’s recent study, which was published in Annals of Tourism Research, argues that rather than purely being a source for the accumulation of human knowledge, the World Wide Web is a sort of destination itself.

As such, the internet offers a medium for the growing online communities of legend-trippers, where interactions in Backroom spaces can become participatory, as opposed to simply being online representations of the kinds of “dark tourism” destinations that become the focus of real-world legend tripping.

According to their findings, James and Cronin argue that a broader understanding and definition of what constitutes dark tourism may be required, which moves the concept of a “destination” away from solely being a physical place and instead makes it a part of a more collaborative digital experience.

The recent study, “When dark tourism goes para-terrestrial: Online legend-tripping and touring the void,” appeared in the May 2026 edition of Annals of Tourism Research.

The space-time oddities of modern physics may have just been taken to a new level of odd, as researchers have revealed that space and time can be used to form a variety of structures that may then be able to become tiny black holes.

The unusual discovery, reported by researchers from Vienna and Frankfurt, presents a new formula for this unusual effect, which they claim can be used to create a crystal-like structure resulting from spacetime self-organization due to a process physicists call critical collapse.

The findings, now reported in Physical Review Letters, reveal the first successful description of this bizarre phenomenon using a novel mathematical trick, which allowed researchers to derive a precise formula for the phenomenon.

Baby Black Holes

Although black holes are often envisaged as large physical structures that result from the powerful conditions involving stellar deaths, not all of them are so monstrous.

In theory, tiny black holes can also exist, emerging from very minuscule critical states where only the smallest amount of energy is introduced. These states, according to physicists, are believed to have once existed immediately after the genesis of our universe, known as the Big Bang, at which time a disorderly blend of particles persisted in the newborn cosmos—conditions that would have been ripe for the creation of what are known as primordial black holes.

These structures are already theoretically verified through computer simulations, although in their recent research, the Goethe University Frankfurt and TU Wien collaboration has now taken the study of these tiny cosmic monsters to a new level by deriving a mathematical formula to confirm longstanding theories about these tiny black holes.

Curving Spacetime at Smaller Scale

According to Professor Daniel Grumiller, a researcher at TU Wien, even the smallest events can sometimes trigger major changes.

“Take liquid water at zero degrees Celsius, for example,” Grumiller recently said in a statement. “A very small change is enough to make the water freeze. The water molecules then spontaneously arrange themselves into a regular pattern and form an ice crystal,” he says.

Why is this significant? A primary reason involves Einstein’s revolutionary ideas about gravity, in which a similar effect occurs, albeit involving space and time. Specifically, Einstein’s theory holds that particles that change locations can cause changes to the surrounding spacetime.

Christian Ecker of the Institute for Theoretical Physics at Goethe University Frankfurt observes that spacetime is warped more strongly in proportion to the size of objects (in other words, those possessing greater mass).

“Large objects such as stars curve spacetime strongly,” Ecker notes. “For example, we can observe this when light rays are deflected by massive stars.” However, massive celestial objects aren’t the only ones that can curve spacetime.

“Smaller masses also produce spacetime curvature, just to a lesser extent,” Ecker explains.

Patterns in Space and Time

According to the researchers, repeating patterns emerge in space and time because of spacetime curvature, in which spacetime can self-organize into a regular, repetitive structure.

This structural form, which they liken to being a sort of “spacetime crystal,” results from a process known as critical collapse.

Grumiller calls the resulting spacetime “crystal,” a “very peculiar and fascinating object,” which he says can be thought of as “a kind of intermediate state, an unstable point that can evolve in two different directions.” Following its formation, Grumiller says that the crystal may then simply dissipate, “leaving behind ordinary spacetime filled with freely moving particles.”

That is, unless an energy input is introduced.

“If a tiny amount of energy is added, the evolution takes a completely different path,” Grumiller says, whereby “the inconspicuous spacetime crystal turns into a black hole.”

Simulating Primordial Black Holes

According to Grumiller and his colleague, Christian Ecker, deriving accurate formulas for such phenomena has proven especially difficult over the years. However, Ecker says they were able to overcome this challenge by instituting a novel trick of mathematics.

“Our universe has four dimensions—three dimensions of space and one dimension of time,” Ecker recently said. “But in principle, nothing prevents us from writing down physical equations for a larger number of dimensions—five dimensions, forty-two dimensions, or even infinitely many.”

Despite the expectation that such conditions might cause theoretical interpretations to become very complicated, the team was able to show that the opposite can be the case, with some questions physicists would normally deem to be extremely complex actually being reduced to relatively simple outcomes.

The team says they hope to explore the possibility that their mathematical formula might be reinterpreted for contexts involving fewer dimensions, which would allow the current models, which relate to the possibility of an infinite number of dimensions, to be scaled back to four-dimensional applications.

So far, doing so has allowed the team to explore four-dimensional universal qualities by taking what one might liken to being a shortcut through a sort of theoretical universe consisting of many dimensions. However, for now, the team’s findings are already proving very promising.

“Our technique turns out to be remarkably stable,” according to Florian Ecker, also with TU Wien.

“Depending on the desired precision, we can systematically improve our formulas using additional approximation methods,” Ecker added. “This gives us a new method for studying black-hole-related phenomena that could previously not be analyzed analytically.”

The team’s recent paper, “Analytic Discrete Self-Similar Solutions of Einstein-Klein-Gordon at Large 𝐷,” appeared in Physical Review Letters on May 12, 2026.

New horizons in the quest to power future computation are being reached, according to researchers who propose a bright idea: using light to power computers instead of electrons.

Since some of the earliest modern computers that were developed beginning in the 1940s, electrons have remained the propellant force behind the technology. However, researchers at the University of Pennsylvania now say that with the 21st century demands of computation in a range of modern applications, addressing the limitations of electron-based hardware is becoming more crucial than ever.

One of the key issues with electron-driven computation involves the limitations of modern computer chips. As these charged particles make their way through these delicate electronic components, the heat they produce is a significant waste of valuable energy.

Add to this the further problems posed by such energy waste in applications that involve artificial intelligence (AI), which has seen an explosion of use in recent years, and the necessity for more energy-efficient computation becomes all-too-apparent.

A Light-Based Approach

Now, a research effort at the University of Pennsylvania led by physicist Bo Zhen in the School of Arts & Sciences is taking a very different approach: the idea that light particles might present a feasible alternative to electron-based computation.

Li He, the first author of a new paper that recently appeared in Physical Review Letters describing the team’s work, says that photons are an ideal alternative, mainly because they are able to “carry information quickly over long distances with minimal loss, dominating communications technology.”

Li, a former postdoctoral researcher in the Zhen Lab, says that one primary reason for this involves the fact that photons are virtually massless, and are neutral particles possessing no charge. However, that isn’t to say that the neutrality of photons doesn’t present a few issues of its own.

“That neutrality means they barely interact with their environment,” Li recently said, “making them bad at the sort of signal-switching logic that computers depend on.” As a result, while light is an optimal medium for the transmission of information—in addition to offering a very efficient alternative to electron-based systems—photonic applications are limited when it comes to the kinds of switching operations in computing at which electrons can excel.

A New Approach

A solution arises with the special case of what are known as exciton-polaritons, which are a variety of particles that form when photons are linked to electrons within a semiconducting material possessing remarkably thin properties of no greater width than a single atom.

Under such conditions, light can interact more effectively for signal switching applications, enabling the kinds of computational tasks that normally only electrons can reliably perform—a crucially important feature when it comes to AI systems, which are often major consumers of energy.

In fact, there are already several light-based technologies in use with AI systems that enable high-speed calculations, although for them to function, they must perform decision-based functions and other nonlinear activation tasks, where the light-based signals are converted back into electrical ones.

The result of this conversion is that the entire process becomes far slower, and overall energy use is increased—effectively canceling out the benefit of current photonic systems and contributing to wasted energy.

The Pennsylvania team says that exciton-polaritons can help to overcome this, as evidenced by their tests, which demonstrated entirely light-based switching using atomically thin materials, resulting in an energy expense of a minuscule 4 quadrillionths of a joule of energy.

Next, the team says, the technology must be scaled for practical use. However, if this can be achieved, photonic chip processing could potentially revolutionize a range of technologies and consumer-level devices, such as cameras, AI-systems, and eventually also future chip technologies that may become the driving force behind quantum computing systems.

The team’s research was supported by the U.S. Office of Naval Research and the Sloan Foundation, and was detailed in a new paper, “Strongly Nonlinear Nanocavity Exciton Polaritons in Gate-Tunable Monolayer Semiconductors,” which appeared in Physical Review Letters.

The Great Pyramid of Khufu, the largest and most impressive surviving monument from the ancient world, has long remained an enigma to scholars. One reason is its remarkable resistance to damage from events such as earthquakes, which has helped it endure for thousands of years without significant structural issues.

Now, researchers say they finally understand the ancient technological factors behind the pyramid’s resilience throughout time.

According to new research, the unique frequency at which the pyramid vibrates during earthquakes contrasts significantly with the sands of the Giza plateau on which it rests. This, a new study in Scientific Reports argues, along with the massive structure’s shape and internal design, has all played a part in helping ensure its longevity.

A Marvel of the Ancient World

Khufu’s Pyramid, often simply called the Great Pyramid, is the oldest of the Seven Wonders of the Ancient World and the sole surviving example. Scholars have maintained a fascination with Giza’s monumental megastructures since antiquity, and debate over the mystery of its construction continues into the present day.

Completed during Egypt’s Old Kingdom (2600–2450 BCE), the Great Pyramid raises a significant question about the structural qualities that have contributed to its longevity. Addressing this aspect of one of the greatest engineering feats of the ancient world, researchers Mohamed ELGabry and colleagues Ayman Hamed, Sakuji Yoshimura, Hesham M. Hussein, Mohamed Maklad, and Asem Salama now say a combination of factors, which include the internal features within the pyramid, all contribute to its success at surviving events that have damaged smaller, more structurally sophisticated monuments in Egypt.

Using Sound to Solve an Ancient Mystery

To help them determine the factors that contribute the most significantly to the longevity of Khufu’s Pyramid, the research team began with an ambient noise survey, which involved horizontal-to-vertical spectral ratio analysis at more than three dozen locations throughout the ancient structure, which included chambers within the pyramid, construction blocks, and adjacent soil.

Their approach was not only successful but also revealed surprising insights into the pyramid’s construction, the team says.

Among the most significant discoveries, the team says they found that the pyramid “exhibits uniform fundamental frequencies (2.0–2.6 Hz) with an average of ~ 2.3 Hz across all structural elements,” revealing an extraordinary consistency in terms of the structure’s dynamic characteristics.

Also important, they say, is that the frequency band the pyramid’s structural components exhibit contrasts sharply with the surrounding soil. This is important because it limits the amplification of resonance through interactions between the stone assembly of the structure and its surrounding soil, which the team identifies as “a key mechanism protecting the monument during seismic activity.

Finally, although the team identifies an increase in seismic amplification with respect to the structure’s height, they also found that it “diminishes substantially within the pressure-relieving chambers,” which they interpret as an indication of “how their geometry actively reduces seismic response.”

Ancient Earthquake Impact Reduction

As a final consideration, the team also examined the pyramid’s subsurface foundation, where they calculated the structure’s vulnerability to seismic events.

After determining a very low value, the team concludes that the pyramid’s foundation has an “excellent bearing capacity and minimal earthquake-induced risk,” noting that, in addition to the monument’s resilience over time, its unique structural properties will likely protect it from future damage.

“The low seismic vulnerability index estimated for the foundation soils suggests that any future earthquakes are likely to produce only limited damage to the main pyramid body,” the team reports in their study.

Arguably, the team’s most significant finding is that the pyramid’s ancient builders possessed an exceptionally advanced understanding of the engineering properties behind the stone used in its construction.

“These findings present compelling quantitative evidence that ancient Egyptian architects possessed profound geotechnical understanding, optimizing structure design and site characterization to assure millennial-scale stability against seismic hazards,” the team reports.

Pentagon Preparing New UAP Release as Lawmakers Push for Greater Disclosure

This week, many speculate that a new batch of Pentagon videos and records related to unidentified anomalous phenomena (UAP) could be made public soon as part of the Department of War’s ongoing PURSUE transparency initiative, with some observers anticipating the next release by the end of the week.

The forthcoming installment, expected to appear under what may become PURSUE “Release 02,” is reportedly set to include dozens of videos currently held by the Pentagon’s All-domain Anomaly Resolution Office (AARO). Many of the videos were first publicly referenced in a March 31, 2026, letter from Representative Anna Paulina Luna (R-Fla.) to U.S. Secretary of War Pete Hegseth, in which Luna requested the release of 46 videos tied to unresolved UAP incidents.

Right now, there are several promising indications that the next release will be on the way very soon.

Here’s a look at what we know.

Subtle New Activity at the Department of War’s PURSUE Page  

Although no new files had appeared at the Department of War’s PURSUE webpage as of Noon Eastern on Thursday, there was one very subtle change that came to our attention at The Debrief.

Specifically, this involved the page’s original “Release 01” designation in the site navigation headings near the top of the page, from which the “01” had quietly disappeared from the site’s navigation bar.

While there are other potential explanations for this, a likely interpretation is that it signals preparations that may be underway for an imminent new “Release 02.”

Descriptions of New UAP Videos

Additionally, descriptions of the forthcoming videos that have already been made available to the public suggest the release could potentially include some of the most unique military UAP footage disclosed to date.

Back in March, an itemized listing of UAP videos currently believed to be in the holdings of the All-domain Anomaly Resolution Office (AARO) was included in a letter from Florida Representative Anna Paulina Luna to Secretary of War Pete Hegseth. Based on the information conveyed in Luna’s letter, we can discern several things about the UAP videos that are currently expected to be released.

For instance, many of the videos reportedly involve spherical objects, a shape category that military personnel and AARO officials have repeatedly identified in recent years. One video allegedly depicts a sphere maneuvering through clouds over Afghanistan in 2020, while another reportedly shows a pulsing orb over water. Additional videos are said to feature erratic movement patterns and unexplained flight characteristics.

Other footage reportedly includes elongated “cigar-shaped” objects similar to the now-famous “Tic Tac” UAP first observed by U.S. Navy aviators during exercises off the California coast in 2004.

“Transmedium” Objects in the New PURSUE Release?

One of the most intriguing categories expected in the release involves “transmedium” objects, which are described as operating both in the air and underwater. According to descriptions contained in Luna’s letter, at least two videos involve unidentified submerged objects (USOs), including one incident from March 2022 in which spherical objects were reportedly observed moving “in and out of water” near a U.S. submarine.

AARO defines UAP broadly as anomalous detections occurring across multiple domains, including airborne, seaborne, spaceborne, and transmedium environments.

In advance of “Release 02,” you can get a complete rundown of everything we currently know about the forthcoming videos in our recent article over at The Debrief, which gives a breakdown of all the new footage, as well as cases that are already well-known, but for which “Release 02” may help provide additional context.

New Support For AARO

Arguably, one of the most promising indicators that the new release will be on the way very soon—possibly within just a few hours—comes from social media, where Representative Luna has recently suggested that the declassification process is already underway.

This much was conveyed specifically in a May 15 posting on X, where the Florida Republican shared a photograph of herself alongside current AARO director Jon Kosloski and Representative Eric Burlison (R-Mo.), writing that they had completed a review of “40+ videos set for declassification.”

“We are standing with the NEW and very QUALIFIED Director of AARO who now has my full support,” Luna wrote, adding that additional releases could arrive “in the coming weeks.”

Whether all 46 requested videos will ultimately be released remains unclear. However, with anticipation building around PURSUE’s next tranche of disclosures, the forthcoming release is likely to renew debate over what the Pentagon knows—and what it may still be withholding—about unexplained objects observed by U.S. military personnel around the world.

A new batch of Pentagon videos and other records related to unidentified anomalous phenomena (UAP) is expected to soon be released by the Department of War, with many anticipating their arrival by week’s end.

The next installment in an ongoing series of Pentagon disclosures is anticipated to include up to 46 new UAP videos reportedly held by the Pentagon’s All-domain Anomaly Resolution Office (AARO).

Although the existence of the videos has been discussed publicly on several occasions by lawmakers in recent weeks, a complete listing of the collection of AARO UAP videos, along with preliminary titles and descriptions of some of the footage, was initially disclosed earlier this year in a letter from Representative Anna Paulina Luna (R-Fla.) to U.S. Secretary of War Pete Hegseth.

“The continued lack of transparency surrounding these anomalies and the potential national security threat they pose is troubling,” Luna’s letter, dated March 31, 2026, reads.

According to Luna, the existence of “additional video records of potential UAP sightings” came to the attention of Luna’s Task Force as a result of whistleblowers who participated in a September 29, 2025, hearing related to UAP transparency. “To continue its investigation, the Task Force requests certain video files related to UAP sightings,” Luna explained to Hegseth in the letter.

Indications of a Forthcoming Release?

The imminent arrival of the videos, originally requested for release by Luna “as soon as possible but no later than April 14, 2026,” is now anticipated by as early as Friday.

On Thursday, the official page on the Department of War’s website for the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE) featured no additional videos or documents beyond those included with the original release, which appeared on May 8, 2026, when the page went live.

However, the heading originally titled “Release 01” that appears in the page’s navigation bar is now missing the “01,” seemingly indicating that preparations for a new batch, tentatively titled “Release 02,” are likely underway.

Update: Thursday, May 21, 2026: Some visitors to the Department of War website also reported throughout the day that, for a short period, the site’s file listing showed up to 140 blank pages. As of 7:23 p.m. Eastern, only the original number of files associated with “Release 01” is available on the site.

What To Expect in the PURSUE “Release 02”

Based on the original list of videos detailed in Luna’s letter from March, along with some descriptions and imagery associated with the videos that have been disseminated prior to their complete authorized release, a few details about what the videos are expected to reveal can be discerned.

One video that Luna and her Task Force have requested reportedly depicts a formation of four unidentified objects flying over an unspecified region in Iran, observed on August 26, 2022.

Another video, reportedly captured in 2021 over Syria, appears to show an object that seemingly displays “instant acceleration,” a capability that would require overcoming several fundamental laws of physics.

While unusual—or even seemingly impossible—physical maneuvers can often be attributed to camera motion and other artifacts arising from the conditions under which such videos are obtained, there are indications that there could be other intriguing footage in the forthcoming batch, a few of which may display a key capability that has increasingly been attributed to some UAP during military observations.

Unidentified Submerged Objects and “Transmedium” UAP

According to AARO, UAP sometimes represent more than just aerial phenomena, with its official definition including “sources of anomalous detections in one or more domains (i.e., airborne, seaborne, spaceborne, and/or transmedium) that are not yet attributable to known actors and that demonstrate behaviors that are not readily understood by sensors or observers.”

Intriguingly, at least some of the files expected in the forthcoming release include videos that purportedly show objects exhibiting what the military characterizes as “transmedium” capabilities, with the objects, described as “USOs” (unidentified submerged objects), reportedly observed both in and out of water.

In at least one of the two USO videos, several spherical objects observed in near proximity to a U.S. submarine on March 25, 2022, are reportedly observed both “in and out of water” in the AARO footage.

Another video, dubbed “UAP USO formation Wiley 2X Zinc,” reportedly shows a different formation of unidentified objects that may be displaying transmedium capabilities.

Spheres Take Center Stage

Several of the videos requested by Luna and other lawmakers reportedly feature what appear to be spherical objects, a common shape class that has been frequently reported by military personnel in recent years, as well as historical reports involving aerial phenomena.

One video, obtained on November 23, 2020, appears to show a spherical object operating in airspace over Afghanistan as it moves “in and out of clouds.” Another spherical object, filmed in 2022, reportedly displays “erratic movement” frequently attributed to such objects, while in a separate video, a spherical UAP is said to have been observed “pulsing” as it passed over a body of water.

Finally, in an incident that occurred on April 12, 2021, a series of three videos was obtained by U.S. personnel depicting a spherical object of unknown origin.

AARO officials have previously expressed interest in this class of objects. In one incident in 2022, an MQ-9 Reaper UAS operating in the Middle East recorded video of a spherical object using its onboard electro-optical sensor. “The object’s characteristics and behavior are consistent with other ‘metallic orb’ observations in the region,” according to a short summary of the footage included in a 2025 AARO mission brief available at its website.

Tic Tacs, Flying Cigars, “Fast Movers”

Spherical objects aren’t the only objects that make appearances in the videos AARO has obtained. Several other varieties of UAP that are commonly recognized from historical accounts are reportedly featured in the videos, which include elongated “cigar” shapes such as the “Tic Tac,” a designation first attributed to an unusual object captured by an FA/18 Super Hornet Pilot during training exercises off the Baja California Coast in November 2004.

One of the new videos describes a “cigar-shaped or fat spherical UAP” observed on October 15, 2022, while another appears to describe a case in which a United States Coast Guard EADS HC-144 Ocean Sentry aircraft observed a Tic Tac-shaped object with its high-definition forward-looking infrared (FLIR) sensor system.

Another video that could be in the forthcoming release involves a trio of “fast moving UAPs” that were observed by U.S. personnel on October 29, 2020. The term “fast mover” is recognized as slang for “fighter jet,” while similar terminology, such as the variant “Fastwalker,” is also occasionally used in relation to UAP sightings.

New Details on the Eglin Air Force Base UAP?

Some of the videos expected in the forthcoming release may offer additional details about UAP incidents that are already well known and for which case resolutions have been produced during AARO’s investigations.

One video in the forthcoming tranche, designated “IIR 1 665 SO301 23/Eglin AFB,” appears to refer to a January 26, 2023, incident involving a U.S. military pilot who observed four objects flying in a diamond formation over the Gulf of Mexico. At the time of the sighting, the pilot claimed that several of his aircraft’s onboard capabilities malfunctioned, requiring them to manually capture imagery of the object.

In a case resolution report on the incident following AARO’s assessment, investigators concluded that the UAP “very likely was an ordinary object and was not exhibiting anomalous or exceptional characteristics or flight behaviors,” concluding that the object the pilot filmed may have been a lighting balloon.

However, AARO’s resolution report added that it had only “moderate confidence in this assessment due to the limited data provided,” a conclusion that drew criticism from even some of the more skeptical UAP investigators.

“The lighting balloon hypothesis always felt like something someone at AARO liked, but wasn’t really supported by much evidence,” skeptic Mick West told The Debrief following the publication of AARO’s report on the incident.

Another of the videos in the forthcoming release was captured by a U.S. Air Force F-16C pilot (callsign AESIR11) during a widely publicized incident that occurred on February 12, 2023, where an object was shot down over Lake Huron with an AIM-9X Sidewinder missile.

According to former AARO director Sean Kirkpatrick, this incident had been one of several involving objects that were later determined to have been hobbyist balloons that were shot down in early 2023, as Kirkpatrick revealed during a recent presentation he gave at the Center for Naval Analyses on April 27, 2026.

Looking Ahead: Cooperation with AARO Continues

Luna has also conveyed to her followers on social media in recent days that the review process required for the release of the new videos was underway, with cooperation from AARO officials.

In a posting on her official X account on May 15, 2026, Luna appeared in a photograph alongside current AARO director Jon Kosloski and Rep. Eric Burlison (R-Mo.), writing that they had just completed the review of “40+ videos set for declassification” by the Department of War, which could be expected “in the coming weeks” as of the time of posting.

“We are standing with the NEW and very QUALIFIED Director of AARO who now has my full support and has proven through action that he is working in good faith on declass efforts,” Luna wrote.

It remains to be seen whether all the videos Luna has requested will be released, although a few glimpses of footage allegedly from the forthcoming batch have already appeared on social media in recent days.

Should the requested tranche of AARO UAP videos arrive in time for the unofficial, but widely anticipated deadline, The Debrief will provide additional reporting on the release of those records, along with any new information they may contain.

For the time being, the records released under the PURSUE initiative are available on the Department of War’s website.

NASA scientists say observations of an unusual phenomenon in the atmosphere of Mars have been confirmed, according to findings detailed in a new study.

The unexpected discovery was made possible with data from the American space agency’s Mars Atmosphere and Volatile Evolution (MAVEN) mission.

This story begins in 2023, when something very unexpected turned up in MAVEN data: NASA scientists observed what appeared to be an atmospheric effect known to occur here on Earth but never seen in Mars’ comparatively thinner atmosphere.

Based on data collected with MAVEN’s suite of instruments, the phenomenon—known as the Zwan-Wolf effect—occurs when charged particles end up being projected out of magnetic structures that atmospheric scientists call flux tubes. The resulting effect, which has been known to occur here on Earth for several decades, is beneficial because it is associated with the deflection of the solar wind around the planet.

“Very Interesting Wiggles”

For researchers like Christopher Fowler, the discovery of anything comparable to this odd atmospheric quirk anyplace other than Earth would have been the last thing he expected to find.

However, that’s precisely what occurred as he began digging into the MAVEN data.

“When investigating the data, I all of a sudden noticed some very interesting wiggles,” Fowler recently said.

As a research assistant professor at West Virginia University in Morgantown, Fowler was admittedly perplexed by what he discovered.

“I would never have guessed it would be this effect,” he said, “since it’s never been seen in a planetary atmosphere before.”

Now, Fowler is the lead author of the recent study that helped confirm its presence in the Martian atmosphere.

An Unlikely Discovery 

One reason the discovery seemed so unlikely is the thinness of the Martian atmosphere compared to Earth’s. Mars lacks the global magnetic field our planet has, which significantly influences how solar winds and other space weather phenomena impact the planet.

Despite such conditions, confirmation of the Zwan-Wolf effect within a particle-rich region of the Martian atmosphere below 200 kilometers revealed that these charged particles were being squeezed in the same way as flux tubes do in our atmosphere, thereby spreading these charged bits of matter throughout the Red Planet’s atmosphere.

According to the team’s findings, they now believe that the Martian magnetosphere, which often changes with solar weather, likely indicates that the Zwan-Wolf effect is constantly at work in the planet’s atmosphere.

However, the effect is mostly undetectable by MAVEN’s instruments. That wasn’t the case in 2023, when space weather events recorded at that time appear to have amplified the effect enough that the NASA spacecraft’s sensors were able to observe it for the first time.

A Martian Swan-Wolf Effect is Confirmed

Still, the initial information the MAVEN team obtained was subtle. Fowler says it amounted to little more than a few notable fluctuations in magnetic field measurements, collected as MAVEN passed through the Martian atmosphere.

Taking a closer look at these “interesting” readings revealed an unexpected surprise, which they ultimately determined to be the same Zwan-Wolf effect known from decades-old studies of Earth’s atmosphere.

“No one expected that this effect could even occur in the atmosphere,” Fowler said of the discovery.

Although the presence of this effect is well-characterized on Earth, understanding its dynamics in Mars’ atmosphere could provide meaningful insights into the forces that drive it elsewhere, including unmagnetized regions like those surrounding planet Venus and moons like Titan.

Additionally, the team believes their work could help to better characterize the changes induced by space weather events and how they can thereby alter the environment on planets like Mars.

“That’s what makes this even more exciting,” Fowler added. “It introduces interesting physics that we haven’t yet explored and a new way the Sun and space weather can change the dynamics in the Martian atmosphere.”

The team’s new study, “Detection of Zwan-Wolf effect in the ionosphere of Mars,” appeared in Nature Communications on May 18, 2026.

Scientists report the development of a new experimental system that could lead to a breakthrough resource in quantum optics by successfully generating correlated photon pairs using sunlight.

The new system relies on nature’s most abundant light source as the main driver of a nonlinear optical process known as spontaneous parametric down-conversion (SPDC), which normally requires a laser to “pump” a nonlinear crystal.

The breakthrough achievement was reported in Advanced Photonics.

Entangled Photons in Correlated Pairs

In the world of quantum optics, the phenomenon of pairs of correlated or entangled photons is an important asset, despite being a seemingly obscure concept for most of us.

Under normal circumstances, optical scientists rely on spontaneous parametric down-conversion (SPDC), a nonlinear optical process in which devices such as coherent lasers are the primary means of “pumping” a nonlinear crystal. Given that they require the kinds of lasers typically found only in top laboratories, the practical use of SPDC is nonviable under normal conditions.

Finding a practical, real-world substitute has long been an intriguing idea, which prompted researchers at Xiamen University in China to determine whether similar processes could be achieved using the most abundant source of light on Earth: sunlight.

A Challenging Process

This is easier said than done, since sunlight, unlike lasers, is generally unstable due to changes in intensity caused by environmental or atmospheric factors (think clouds, for instance) as well as changes in angle and position that occur naturally throughout the day.

All these factors compromise the precision required for SPDC. Still, the practicality of sunlight, as well as the energy it provides, has continued to make it a potentially feasible alternative that scientists hope might liberate SPDC from its reliance on lab-grade coherent lasers.

If it could be harnessed for such purposes, using sunlight to fuel SPDC would also mean that photon-pair generation could be achieved in remote areas where researchers had never previously considered it possible.

A Solution to SPDC Beyond the Lab?

According to the Xiamen University research team, a new experimental system has been developed that uses sunlight as the only pump source for this process, employing a device that tracks the sun, similar to how equatorial mounts allow astronomers to follow the movement of celestial objects as the Earth spins.

The device, according to researchers, harnesses sunlight at the proper angles throughout the day, which is then fed through a length of optical fiber to an indoor lab. From there, the light is used to pump a potassium titanyl phosphate (KTP) nonlinear crystal.

Periodically Poled Potassium Titanyl Phosphate (PPKTP) crystals are a variety of engineered nonlinear optical crystals that researchers use for high-efficiency frequency conversion and other quantum optics applications, especially for creating entangled photon pairs. They work by altering qualities of light that include its color, phase, or frequency by forcing it to pass through a specially engineered component or structure.

While using sunlight as the sole source of illumination for such processes is complex, the team found that its system successfully produced photon pairs that exhibited strong correlations.

Ghost Imaging for Photon Pair Production

Next came the demonstration phase, where the team used the photon pairs generated by their new system to perform “ghost imaging,” a process that uses correlated photons to produce imagery rather than spatial detection.

While conventional laser-based systems can achieve better than 95 percent visibility at comparable pumping power levels, the team’s sunlight-powered technology achieved ghost imaging visibility of 89.7 percent, well within the range of lab-based systems. To further illustrate the system’s use with more detailed spatial structures, the team also used it to produce, appropriately enough, a two-dimensional image of a ghostly face.

Overall, the team says quasi-phase matching in the PPKTP crystal was achievable with the broad spectrum of sunlight, enabling them to generate an abundance of position-correlated photon pairs. Additionally, the team reports that their system yields better signal-to-noise and contrast-to-noise ratios, even given the challenges posed by sunlight variability when used as a primary energy source.

Practical Use Beyond the Lab

“Our research holds substantial significance as it expands the range of viable illumination sources,” the team writes in their recent study, “including scattered light and nontraditional artificial incoherent light—for imaging applications.”

They add that among the potentially promising uses for their technology, space-based quantum information systems may be particularly beneficial, since the team’s new method “enables operation independent of laser sources.”

The team’s new paper, “Sunlight-excited spontaneous parametric down-conversion for ghost imaging,” appeared in Advanced Photonics on April 24, 2026.
