A remarkable discovery has been made in East Africa’s Lake Malawi, one of the deepest bodies of water on the African continent.

Africa’s impressive lakes have long remained a focus of speculation for naturalists, involving folklore about strange creatures—including supposed holdovers from prehistoric times—alleged to inhabit some of their waters.

However, a much smaller discovery made by a team of researchers with the Department of Zoology at the University of British Columbia (UBC) at Vancouver, Canada, is nonetheless challenging our past thinking on what kinds of life forms can be found lurking in the depths of some of Africa’s storied lakes.

In a remarkable discovery, a variety of lake fly larvae have been found descending into the very oxygen-deprived depths of Lake Malawi, where they hide more than 650 feet below the surface to avoid predators.

After spending their days in this deep-water “dead zone,” the larvae reemerge at night and feed—or at least some of them do, if they are lucky enough to escape the fish searching for a dinner of their own, while these tiny insects are commuting back to the surface.

A Surprising Discovery Deep in Lake Malawi

To chart the unusual daily cycle of these larvae, UBC researchers Dr. Philip Matthews and Dr. Evan McKenzie used sonar technologies, which were positioned deep within the lake.

While this provided an idea about where these tiny insects were going, it was dissecting the larvae that revealed how these remarkable little creatures have somehow evolved a respiratory system that contains two pairs of small air sacs, which function like ballast tanks, allowing the larvae to control their buoyancy.

Within these sacs, they discovered the presence of resilin, a material that can either expand or contract in proportion to changes in the pH of the sac’s walls. As a result, the larvae can change the volume of these unique air sacs, thereby controlling their buoyancy.

It is an unusual capability these creatures display, to say the least. Curious about how deep they might be able to go, the researchers placed several of the larvae within small pressure chambers to simulate the depths they might travel to before the sacs imploded.

Much to the team’s surprise, these natural buoyancy systems held out under conditions that would match depths of 400 meters (1,312 feet), which is much deeper than what the sonar data reveals about the larvae’s daily descents into Lake Malawi.

While it has long been assumed that insects, which often thrive in freshwater environments, do not live in open oceans due to such pressures associated with the depths of the world’s largest bodies of water, these African insect larvae reveal that such creatures can survive under such conditions.

Based on their findings, the UBC researchers hope to work on finding ways of simulating such capabilities, perhaps by creating pH-powered resilin smart materials, or even artificial systems that emulate the way muscles operate.

The team’s findings appeared in the new study, “Crush-resistant air sacs allow insect larvae to exploit aquatic habitats at extreme depth,” published in the journal Science.

Pentagon’s AARO Releases Long-Delayed UAP Report

This week, the Pentagon’s All-domain Anomaly Resolution Office (AARO) finally released its 2025 annual report on unidentified anomalous phenomena, or UAP.

You read that correctly: the long-delayed report for fiscal year (FY) 2025 has been MIA since its expected release date last October, and finally appeared at AARO’s website just three months (or so) ahead of the scheduled release date for its next annual report. Hey, better late than never.

According to AARO’s latest findings, there were no cases it resolved that point to advanced foreign technology or extraordinary capabilities exhibited by UAP, but close to 200 reports from its latest batch remain unexplained due to insufficient data.

AARO also reiterated two conclusions that have remained consistent across previous reports: investigators have found no evidence that the U.S. government or any private organization has recovered or exploited materials derived from UAP, and the office has received no verified reports of adverse health effects directly associated with UAP encounters.

Beyond that, here’s a look at some of the report’s primary findings.

Key Findings in AARO’s 2025 Report

Offering an overview of the office’s investigations of cases collected between June 2, 2024, and May 30, 2025, the new report conveys that AARO received 319 new UAP cases during the reporting period, bringing its total case holdings to 1,870 since the office’s creation.

274 incidents occurred in the air domain, while 44 involved objects observed in space, and one occurred in the maritime domain. “The single maritime domain UAP case AARO received involved a report from U.S. Navy assets operating off the coast of Virginia,” AARO’s report states. “The report described approximately 100 airborne UAP and two, likely uncrewed, surface systems. AARO is actively investigating this event in coordination with the reporting unit.”

The brief description of this single maritime incident AARO received is intriguing, although very little context is provided, and it is unclear whether it may be describing UAVs and uncrewed launch platforms observed at sea, which might be attributable to a U.S. foreign adversary.

A Whole Lotta Satellites

As for those “objects observed in space,” AARO’s report makes it clear that none of the space-domain cases originated from space-based sensors, but instead mostly came from civilian pilots reporting through the Federal Aviation Administration (FAA). The other two originated from U.S. Space Command ground-based sensors.

“AARO applied all-source analysis techniques and three-dimensional modeling to render a high confidence assessment for each of these cases as being attributable to satellite flaring,” the report reads.

The fact that satellite flaring has significantly contributed to recent alleged UAP sightings is nothing new. In 2022, following a series of sightings by pilots involving what were characterized as “racetrack UAPs,” it was determined that the sightings resulted from an optical illusion created by SpaceX Starlink satellites.

While 114 of the 319 new cases AARO has received have been resolved, it says that 191 cases have been placed into AARO’s “active archive,” which involves reports that presently lack sufficient data required to make an assessment.

“UAP cases held in active archive inform AARO’s locational and trend analyses and remain open to future resolution should further information or improved analytical techniques enable a more conclusive resolution,” the report states. Additionally, there were nine cases referred to members of the Intelligence Community and AARO’s science and technology partners for further technical analysis.

Trends in the Data

The report also identifies several trends among the incoming reports. In terms of appearance, spherical shapes remain the winning category, comprising close to 40 percent of reported UAP morphologies, with lights representing around 33 percent. Around 25 percent of sightings lacked enough information to give any clear indication of shape at all.

In terms of altitude, most airborne sightings occurred between 10,000 and 35,000 feet, while reports above 45,000 feet declined significantly from the previous reporting period; notably, AARO attributes this to its progress in identifying satellite flares.

Fortunately, no flight safety-related incidents were reported for the period discussed in the FY 2025 report, although there were two cases that “contained descriptions of electronic or avionic interference reported as attributable to UAP in proximity to an operational aircraft.” AARO says it remains unclear whether those effects were directly related to the observed UAP.

UAP Near Critical Infrastructure?

Perhaps one of the most significant elements of the new report is that there were reportedly several new cases logged near sensitive military installations and critical infrastructure. “Some narrative reports were suggestive of phenomena whose performance characteristics exceed the known state-of-the-art within a given domain,” the report states, though adding that “No technical data accompanied these reports.”

“If validated, the attendant phenomena underlying these reports may represent a currently unmitigated threat vector,” the report states. “Part of AARO’s mission is to provide data and analysis that helps mitigate potential UAP-related national security threats or operational hazards.”

The report additionally documents a significant increase in reports involving unmanned aerial systems operating near U.S. nuclear infrastructure, with 50 incidents referred to AARO by the National Nuclear Security Administration and Nuclear Regulatory Commission—a 178 percent increase over the previous year’s total.

It is clearly stated that none of these objects were genuine UAP or exhibited anything unusual. “The reports contained descriptions of UAS morphologies ranging from small hobbyist-sized UAS to larger multi-rotor models. Quadcopters were the most reported morphology,” AARO’s report states.

As with past AARO annual reports, the FY 2025 updates leaves much to the imagination—a fact that is very in keeping with recent UAP imagery and documentation released by the Pentagon through its PURSUE initiative. Still, the report’s findings—vague as they are—do indicate one fundamental issue: objects or phenomena that remain difficult to attribute to any known sources continue to be tracked by U.S. defense personnel.

With nearly 2,000 reports in its current collection, AARO concedes that while it has found no evidence of links to any extraordinary phenomena, there are also still a good number of cases that remain unresolved, and which warrant further attention.

Perhaps that’s the real takeaway—not that AARO has found evidence of anything extraordinary, but that some reports do continue to defy straightforward explanation.

Here are the top stories we’re covering right now…

In the millennia that followed the last Ice Age, early humans began making their way into the inland mountains of southern Norway as ancient glaciers receded, revealing new portions of the landscape.

However, the landscape in this region made it impossible for fish to make their way upstream into high mountain lakes, impeded by waterfalls and other barriers. Somehow, fish appeared in these upland bodies of water anyway—so how did they get there?

The natural answer to this ancient question is that humans must have carried fish from regions further downstream, populating these ancient and once-lifeless lakes with an abundant food source. The question archaeologists have been unable to answer is when, precisely, these ancient transplants of wildlife took place.

Now, archaeologists with the University of Oslo believe they have finally solved this longstanding riddle, with the discovery of the remains of 7,000-year-old fish traps that reveal the likely period during which early Mesolithic inhabitants of the region engaged in some of its earliest fish farming.

The discovery not only offers archaeological evidence for when fish were likely first introduced into the region, but also reveals that agriculture was not the only means of nature management that these early Norwegians engaged in.

“For more than 100 years, it has been known that the fish inhabiting watercourses in the Norwegian mountains are descended from specimens translocated by humans,” says Axel Mjærum, a researcher at the University of Oslo and the lead author of a new study detailing the findings.

“However, until now, it has remained unclear when people first began transporting fish upstream into lakes and rivers that originally lacked natural fish,” he adds.

A 7000-Year-Old Discovery Leads to a Breakthrough

Offering a rare opportunity to unravel some of this mystery, the discovery of ancient fish traps constructed from wood, the remnants of which were discovered in southern Norway’s Lake Tesse, provided a unique look at the period during which fish transport and harvesting likely began.

Radiocarbon dating of the wood from the traps reveals that Salmo trutta, the region’s brown trout species, were relocated to the lake during the Mesolithic period.

Growing to considerable sizes, this species of trout was an ideal, high-protein food source that could readily be harvested from the lake once a thriving population had been established.

Although agriculture would later become a major source of food for these ancient Scandinavians, the period during which the fish traps are dated to predates farming in the region, which supports the idea that these people were hunter-gatherers, and also fishermen.

Environmental Management in Ancient Scandinavia

More broadly, the findings by Mjærum and his colleagues reveal the degree to which these Mesolithic Scandinavians were managing their food supply through direct control of the natural environment, setting the pace for several more millennia of food production.

Even today, brown trout are among the many fish species sportsmen harvest—the descendants of the very same fish originally carried to southern mountain Norwegian lakes thousands of years ago.

Mjærum says that the ancient Mesolithic Norwegian’s “release of brown trout into previously fishless lakes in the Norwegian mountains around 5000 B.C. is a very clear example of humans’ general capacity to reshape entire ecosystems, even before the introduction of farming.”

The study, “The introduction of fish to the Scandinavian mountains by hunter-fisher-gatherers 5000 BC,” appeared in the journal Antiquity.

Scientists are sounding the alarm over a worsening situation in Earth’s oceans and freshwater systems, according to a new study that warns of “irreversible” changes our planet could be facing.

New research led by the Scripps Institution of Oceanography at UC San Diego has revealed the rapid disappearance of oxygen from bodies of sea and fresh water, leading to environmental changes that could endure for centuries if left unmitigated.

The new study, which appeared in the journal Limnology and Oceanography, argues that widespread aquatic deoxygenation—reduced levels of dissolved oxygen in oceans and coastal waters, lakes, rivers, and streams—is increasingly becoming a problem, and one that influences nine other crucial environmental processes.

These processes are all included in what is known as the Planetary Boundaries framework, a science-based tool that outlines the requirements of a safe operating space for humanity. Introduced in 2009 by Earth system scientists led by Johan Rockström, this framework identifies nine critical environmental processes that regulate Earth’s stability.

Specifically, the nine planetary boundaries outlined in this framework are climate change, biosphere integrity, land use changes, biogeochemical flow of nutrients, ocean acidification, freshwater changes, atmospheric aerosol loading, stratospheric ozone depletion, and pollution.

Now, the Scripps researchers behind the recent study say they believe dissolved oxygen levels should also be formally included in this framework.

Aquatic Deoxygenation is a Growing Concern

Erica Ferrer, a Scripps Oceanography alumna and current postdoctoral scholar at UC Santa Barbara’s National Center for Ecological Analysis and Synthesis and lead author of the new study, says that her team’s work “is designed to elevate the profile of aquatic deoxygenation as a global threat and show that it does not operate in isolation.”

“The health and stability of our planet depends on the health and stability of aquatic ecosystems, which need oxygen to function normally,” Ferrer said.

Driving this growing problem, the new research says, is the excessive influx of nutrient pollution into water bodies, as well as anthropogenic warming, and changes occurring in natural ventilation systems within deep ocean waters.

With depleting oxygen levels scientists are seeing, longer-term changes to chemical and biological processes that regulate our planet’s climate are expected to occur. The decline, Ferrer and her colleagues argue, is also likely to impact a diverse range of aquatic organisms and ecosystems.

Even ocean mammals that acquire air at the surface are likely to be impacted, since deoxygenation can either cause the relocation or outright depletion of the organisms that make up their diets. This, in addition to causing severe damage to habitats and alterations to the food webs they depend on.

Ferrer and her colleague, study co-author and Scripps biological oceanographer Lisa Levin, are hopeful that their findings will encourage a deeper level of engagement on the potential ramifications of aquatic oxygen loss, and how other environmental challenges outlined in the planetary boundaries framework can act as multipliers, rather than separate existential concerns.

“Adding aquatic deoxygenation to the Planetary Boundaries framework will help us understand its impacts on Earth system stability,” Ferrer said in a statement, adding that mitigation of ocean deoxygenation impacts “represents a critical component of maintaining biodiversity and climate.”

Levin, Ferrer, and their colleagues’ study, “Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest ‘unsafe’ levels of oxygen loss with far‐reaching impacts,” appeared in the journal Limnology and Oceanography on June 30, 2026.

A three-dimensional thermal cloak that can conceal objects from heat, while also shielding them from extreme temperatures, has been developed by researchers in a breakthrough with significant potential for quantum electronics and military stealth technologies.

The breakthrough, led by University of Illinois Urbana-Champaign civil and environmental engineering professor Shelly Zhang in collaboration with colleagues at the Technical University of Denmark, differs from past thermal cloaks that only function in two dimensions, or in a single direction.

The team’s new device is capable of guiding heat around an object, regardless of the origin point of the heat source. When used with an infrared camera, the cloaked object effectively disappears, while the temperature inside the protected region remains stable.

The team’s achievement was detailed in a new study published in Nature Communications.

A Novel Approach to 3D Thermal Cloaking

Unlike previous thermal cloaks, which only worked in two dimensions or from a single direction, the new device guides heat around an object regardless of where the heat originates. To an infrared camera, the cloaked object effectively disappears, while the temperature inside the protected region remains stable.

“A real thermal cloak should work no matter where the heat comes from,” Zhang said in a recent statement. “Our device can hide a complex 3D object in an infinite number of directions while keeping the temperature inside stable and protected.”

As opposed to blocking heat, Zhang and her team’s new cloak redirects it around an object, preserving the temperature field in the surrounding area as though nothing were present.

Although the concept has existed theoretically for many years already, researchers have encountered challenges when it comes to practically leveraging such capabilities.

Redirecting Heat Around Hidden Objects

To overcome past hurdles engineers have faced, Zhang and her team designed a novel lattice-based material, which exhibits thermal properties that allow it to be “tuned” with a great degree of precision in three dimensions.

By combining a 3D-printed aluminum lattice, which serves as a good heat conductor, with a molded rubber-like material that functions as a thermal insulator, the team was able to control the flow of heat through different regions of the device. Additional lab testing helped to confirm its functionality as intended.

Placed between hot and cold environments, the cloak redirected heat around hidden objects, producing an external thermal pattern which they say appeared essentially undisturbed. Simultaneously, temperatures within the cloaked region remained largely uniform, despite the surrounding thermal gradient.

As a further demonstration of its capabilities, the researchers then successfully concealed objects with highly complex three-dimensional geometries, which included detailed head-shaped models that they say surpassed the performance of past versions of thermal cloaks.

Defense and Security Applications

Zhang says the technology could have a wide range of potential applications, especially where precise thermal control is a requirement.

“Any field that needs precise control of heat or needs to protect something from being detected thermally could benefit from this work,” Zhang said in a statement, “But we also see it more broadly: it’s about hiding and protecting information that is carried by heat.”

Additionally, the technology could have applications involving the use of similar cloaks to protect sensitive electronics and microchips from damaging heat, improve thermal management in advanced computing systems, and shield equipment from detection using infrared, which may be useful in security and defense technologies.

Going forward, the team plans on exploring more advanced designs capable of concealing objects that generate their own heat, which could pave the way toward more active thermal cloaks in the coming years that could dynamically manipulate heat and still remain effectively invisible to infrared sensors.

The team detailed their research in a recent paper, “Free-form thermal cloaks in three dimensions,” which appeared in Nature Communications.

An unusual underwater discovery has been revealed in Germany’s Lake Constance, where archaeologists are investigating the well-preserved remains of a medieval shipwreck.

The discovery, which dates back to the 15^th century, offers a rare look at the shipbuilding and navigation technologies once used to traverse one of the most historically important inland waterways in Europe.

Discovered near the city of Lindau, the find was made after a local recreational diver spotted what appeared to be wooden remains on the base of the lake, according to underwater archaeologist Prof. Tobias Pflederer, honorary president of the Bavarian Society for Underwater Archaeology.

The diver alerted archaeologists from the BGfU about the unusual wooden structure, who were able to confirm that the timbers belonged to the remains of a previously unknown vessel, Euro News reported.

“What was particularly exciting was that we were really able to identify the wooden remains as a wreck,” Pflederer said in a German-language statement. “But after several frames and fragments of the hull were protruding from the lakebed, the interpretation quickly became clear.”

A 15th Century Find Resurfaces

Based on the condition of the wooden ship’s remains, it is estimated that the vessel once measured between eight and twelve meters in length, with a beam of approximately three meters.

Analysis of wood samples from the wreck was undertaken with help from the Bavarian State Office for Monument Preservation, which revealed likely dates as old as 1420 AD. This makes the discovery one of just a handful of late medieval shipwrecks archaeologists have discovered in Lake Constance.

“So far we have carried out only two dives and have done just an initial survey,” Pflederer said, adding that researchers had documented the site using underwater orthophotography before collecting a small timber sample, which they used for radiocarbon dating.

What Sinks Remains Sunken

While the discovery is significant in terms of medieval sailing vessels, Pflederer and his colleagues say there are currently no plans to recover the vessel, since raising the wreck would require extensive conservation efforts that would be both technically challenging and also quite costly.

Given its current condition, the best means of preserving the wreck, for now, will be to leave it beneath the lakebed, where it is offered some degree of natural protection from sediment that has accumulated over it.

Future investigations of the centuries-old timbers that remain within Lake Constance may offer additional insights into how the vessel was constructed, and allow researchers to determine its precise dimensions, potentially adding new insights into medieval commerce and navigation on Lake Constance.

Researchers have revealed a microscopic engine that can convert heat into useful work while operating at temperatures only fractions of a degree above absolute zero.

Tinier than a single grain of sand, the machine marks the first demonstration of what researchers call a cyclic quantum heat engine composed of superconducting circuits, the technology behind modern quantum computers.

The findings, led by Academy Professor Mikko Möttönen, were published in Nature Communications.

A Sand-Grain-Sized Quantum Heat Engine

The tiny device, developed by researchers at Aalto University in Finland, relies on a single superconducting qubit, which represents the quantum world equivalent of a classical computer bit.

By heating, cooling, and extracting energy through quantum variations of the cycles that provide power to conventional engines by thermodynamic means, researchers say the machine’s demonstration of producing energy, while extremely small, marks a breakthrough that could one day allow for the simplification of much larger-scale quantum computers.

A flux-tunable transmon qubit—one of the most common building blocks of superconducting quantum processors—lies at the heart of the innovation. But as opposed to relying on separate hot and cold reservoirs, the Möttönen and the Aalto University research team used a single quantum circuit refrigerator capable of performing both roles.

The team guided the system through a sort of quantum version of what is known as an Otto cycle (the same essential process most gasoline engines employ) by leveraging precise control of the refrigerator and the qubit’s energy levels.

“In our experiment, we built a nanofabricated heat engine using superconducting circuits and operated it in a cryostat near absolute zero,” said lead author Tuomas Uusnäkki. “At its heart is a transmon qubit, one of the basic building blocks of modern quantum technologies.”

Single Shot Measurements on Repeat

The team also used repeated single-shot measurements to track the qubit, observing as it completed several engine cycles. This helped them calculate precisely how much heat was absorbed, as well as the amount of work produced, and the machine’s overall efficiency.

The results, they say, closely matched theoretical predictions, and now help to confirm that the device functioned as a genuine cyclic quantum heat engine.

Although this is not the first quantum heat engine, and previous demonstrations have been achieved using trapped ions, ultracold atoms, and other quantum systems, the Aalto team says this is the first that operates using superconducting circuits, which could present new possibilities for the future of quantum computing.

As quantum computers grow, such technologies could be especially helpful, since today’s superconducting processors rely on extensive networks of microwave cables connecting room-temperature electronics with processors that operate near absolute zero—the lowest temperature theoretically attainable.

These networks of cabling not only take up space, but also add to costs, while adding to the overall heat and electrical noise in systems that can also introduce interference affecting fragile quantum states.

A Look at the Future of Quantum Computing

With future refinements of their technology, the Aalto team hopes versions of their tiny engine may be able to perform control functions directly within cryogenic quantum processors, thereby reducing the need for external wiring altogether.

“Finland’s Quantum Technology Strategy envisions a quantum computer with one thousand logical qubits by 2035, which probably means hundreds of thousands of physical qubits,” Möttönen said in a statement, describing future large-scale quantum computers.

“Doing that with current technology requires millions of microwave cables costing thousands of euros each,” he added.

“The cables also introduce noise into the system,” Möttönen said. “Using autonomous devices instead would mostly eliminate the need for those cables.”

The team’s recent study, “Initial demonstration of a quantum heat engine based on dissipation-engineered superconducting circuits,” appeared in Nature Communications.

New NASA imagery has revealed a growing Martian “crescent” and surface details on the Red Planet as the agency’s Psyche spacecraft recently completed a flyby of Earth’s nearby planetary neighbor.

Launched on October 13, 2023, Psyche is currently on its way toward a rendezvous with a metal-rich asteroid after which the space probe was named. Now, in a series of composite images captured as the spacecraft flew past Mars during a gravity assist in early May, the growing crescent shape of the Red Planet is shown in successive views of Earth’s nearby planetary neighbor.

“After these views were captured by the spacecraft’s multispectral imager instrument, Mars began to overfill the field of view as Psyche made close approach with the planet and captured a series of high-resolution images of the surface,” read a NASA statement accompanying the imagery.

In several of the images, Mars appears as a thin sliver due to the high phase angle of approach as Psyche made its way toward the planet. In the days that followed, the crescent is shown as it appears to “grow” as more sunlight illuminates its surface.

A Detailed Glimpse of the Martian Surface Captured by Psyche

The recent crescent features weren’t all that Psyche captured during its recent near approach to Mars. In additional images released by the American space agency, the Martian surface appeared in colorful views obtained by the spacecraft’s multispectral imager instrument.

The resulting “mosaic” was created from four separate images acquired near the end of Psyche’s recent visit, shown in enhanced color that highlights several details visible on the Martian surface.

Traveling along a southwesterly path with relation to the Martian poles, the mosaic imagery appears slightly blurry, as it represents close to six minutes of travel above the planet. According to NASA, pixel scale resolution in the imagery “varies from 381 meters per pixel on the right to 440 meters per pixel on the left.”

Color enhancements to the imagery, collected with the imager’s green, blue, and near-infrared filters, reveal additional details about the various features of the volcanic region of Mars that Psyche flew over on May 15, 2026, known as the Iapygia region.

This area comprises part of the Martian southern highlands, and in the recent imagery, Fournier crater—the largest shown in the new imagery—can be seen, alongside hills, cliffs, and other features, including the irregular Oenotria Scopuli cliff system, forming one side of the boundary of a massive ancient impact feature on the Red Planet.

Last summer, astronomers were observing the near approach of a space object believed to be an asteroid that had been tracked since its discovery in 1998. However, in a surprising development, the object failed to appear where it was predicted to be after decades of observations.

Now, a team of researchers reports in a new study that this mysterious orbital body is no asteroid at all, but instead may be an elusive class of space objects that scientists are still working to fully understand.

The research, published in the journal Nature Astronomy, identifies the newly suspected reasons for this unexpected “dark” twist in the developing story of 1998 SH2, a celestial body once thought to be a common space rock that is now upending past thinking on how to protect Earth from potential impact risks.

1998 SH2’s August Surprise

Since its discovery in 1998, the object designated 1998 SH2 has been monitored by astronomers continuously, providing close to three decades of observations that inform us about its orbit, leaving what researchers thought would be little room for surprises.

That all changed last August as the anticipated return of 1998 SH2 approached. Based on radar observations, the object appeared to be absent from its expected orbital path—a mystery that initially baffled astronomers.

Eventually, once the near-Earth object was spotted again by Brazil’s Southern Observatory for Near Earth Asteroids Research, it had moved significantly beyond its expected path. But what could account for such an unusual display?

When AN Asteroid Goes “Dark”

Now, according to Jet Propulsion Lab and CalTech researcher Davide Farnocchia and colleagues, 1998 SH2 was likely steered off course as a result of jets of gas escaping from beneath the object’s surface—a phenomenon known as weak cometary outgassing—meaning that the suspected asteroid is actually probably a type of comet.

However, unlike most comets, this one showed none of the typical characteristics astronomers associate with them, including a glowing tail or coma. This helped to explain the confusion over its initial classification, and additional observations of layered composite imagery did finally reveal these features, albeit faintly.

This confirmation that the object was indeed releasing material meant that 1998 SH2 was a rare variety of space objects known as dark comets, enigmatic bodies whose subtle behavior falls somewhere between comets and asteroids.

Planetary Defense Implications

One of the more concerning aspects of the discovery involves 1998 SH2’s unexpected orbital shift, which presents the question of whether other suspected asteroids might turn out to be dark comets. If so, could any of these shifty space objects pose a risk to Earth?

Fortunately, Farnocchia and his colleagues say there is currently no indication that 1998 SH2 poses an impact threat to Earth in the foreseeable future. Still, the team’s findings do have important implications for planetary defense, since their findings underscore the possibility that additional near-Earth objects currently classified as asteroids may turn out to be hidden comets.

Given the unpredictable orbital shifts and changes in acceleration these objects display, challenges associated with identifying and tracking them could complicate long-term impact forecasts, and influence how future deflection missions are designed.

Fortunately, the team’s study also highlights beneficial findings, which include the possibility that a hidden population of dark comets could potentially resolve questions about how water was delivered throughout the early solar system, eventually making its way to a young planet Earth billions of years ago.

Additionally, such possibilities could help to explain past observations of enigmatic objects like ‘Oumuamua, the first confirmed interstellar object, whose detection in 2017 and unexplained acceleration during subsequent observations have fueled scientific debate over its origins for many years.

Farnocchia and his colleagues’ new paper, “Non-gravitational acceleration indicative of cometary activity of near-Earth object,” appeared in Nature Astronomy.

FCC Approves Launch of Satellite Designed to Reflect Sunlight to Earth’s Nightside

This week, in a controversial ruling that has sky watchers (and others) concerned, the U.S. Federal Communications Commission (FCC) approved the launch of an experimental satellite crafted to reflect sunlight onto Earth after sunset.

The move has seen significant pushback from astronomers, who now warn that the technology would likely interfere with scientific observations and alter the natural appearance of the night sky.

Dubbed Eärendil 1, the satellite is being developed by the California-based Reflect Orbital as a proof-of-concept for the company’s larger, and potentially even more impactful vision: as many as 50,000 orbiting mirrors capable of directing sunlight to different regions on Earth.

While astronomers have expressed concern over the implementation of such orbital systems, the company says its satellites would offer the possibility for providing illumination after dark in select areas, which could be used to extend the operation hours for solar powered facilities.

Eärendil 1: A Case Study in Controversy

Branding itself as “the sunlight company,” Reflect Orbital says in a statement at its website that it aims to provide “clean, abundant energy available on demand,” because “reliable access to affordable energy is the foundation of human progress, economic growth, and a healthier planet.”

The satellite, which shares its name with Eärendil the Mariner, a character from J.R.R. Tolkien’s mythos, will carry an 18-by-18-meter (59-by-59-foot) reflective Mylar surface that unfolds in orbit after launch. Operating roughly 625 kilometers (390 miles) above Earth, the spacecraft is designed to redirect sunlight onto specific target areas of approximately five kilometers (three miles) in width.

Although many are sounding the alarm about the potential consequences of such technology, the Reflect Orbital says it maintains strict exclusion zones where astronomical operations or “sensitive areas” exist, and that its technology can be carefully deployed only to regions identified as target areas.

According to a FAQ page on the company’s website, the light produced by Eärendil 1 and future members of the company’s constellation will be “contained within the spot” among several other safety features it promotes. The company also says it can turn off the light quickly, and disable it at any time to prevent light from reaching Earth.

“The light is not bright enough to start fires or harm eyes,” the company’s FAQ page states, “even when viewed through a telescope, and cannot be concentrated past maximum natural sunlight irradiance.”

The company’s CEO, Ben Nowack, has argued the concept could improve the economics of solar power overall, allowing Earth-based power systems the ability to harvest additional sunlight before sunrise and after sunset.

Criticism Abounds

The proposal has drawn criticism from several groups, particularly the American Astronomical Society (AAS), which urged the FCC to reject the application.

“The American Astronomical Society (AAS) is dismayed by the Federal Communications Commission (FCC) decision on 9 July to grant a license to Reflect Orbital,” the organization said in a statement following the FCC ruling. “As the AAS expressed to the FCC, Reflect Orbital’s proposed satellite, which would reflect sunlight back to Earth at night, carries the potential for significant harm to our members and the broader community of those who depend on a dark night sky.”

“This harm could include damage to sensitive research telescope equipment, potential flash-blinding of pilots and drivers, and — as Reflect Orbital stated in its own FCC filings — potential permanent eye damage to anyone looking through a mid-sized telescope,” the AAS statement adds, noting what appears to be a sharp contrast between information contained in FCC filings, and that which appears on the company’s website.

Further, research cited by the AAS suggests that a full constellation of Reflect Orbital satellites could increase nighttime sky brightness by a factor of two to three, even at remote observatories, due to atmospheric scattering of the reflected light.

“While we fully support American technical innovation in space, this innovation cannot come at the cost of imperiling scientific research, which has been at the forefront of American innovation and global leadership for decades,” the AAS statement concludes.

Beyond FCC Authority

However, in the wording featured in the agency’s approval, the FCC concluded that such concerns fall outside its authority, which is primarily limited to regulating the use of radio-frequency spectrum, adding that it believes the overall likelihood of injury resulting from the launch of the proof-of-concept satellite to be low.

In the meantime, while the FCC’s approval marks an early win for Reflect Orbital, the company has said that it is planning to have independent research commissioned to help assess the technology’s environmental and scientific impacts. Additionally, the company says it plans to coordinate with the National Science Foundation to help ensure that its efforts align with those of the broader scientific community.

Fundamentally, the AAS’s disappointment—a view expressed by other members of the scientific community, argues that the ruling presents broader questions about who should oversee the environmental consequences of future space-based illumination projects, especially if such systems end up becoming more widespread in the years ahead.

“In the absence of another licensing agency that could take these considerations into account, we believe that it is critical for the FCC to consider all of the impacts of the satellite’s use case,” the AAS said in its statement this week.

America at 250: The Heat is On

Depending on where you are at the time you’re reading this, you may have noticed the temperature. Safe to say, summer has arrived.

One reason involves the “heat dome” that is covering much of the East Coast and the Midwest, with temperatures topping 100 degrees across large portions of the U.S., including the nation’s capital. As a result, the country’s power system is undergoing inevitable strain as extreme heat warnings have prompted grid operators to warn about surges in air-conditioning use throughout the nation, with many systems expected to operate less than optimally amid such temperatures.

All of this arrives just in time for America’s 250th birthday, with Independence Day celebrations falling on a weekend that is certain to be memorable for more than just the extreme heat, since this year’s celebration marks our nation’s semiquincentennial.

“Reaching 250 years is a significant event for any nation,” read a statement by the Sandra Day O’Connor Institute in honor of the forthcoming holiday. “It offers a chance to learn more about how the United States began, how it grew, and how it has changed over time. Every era of American history has shaped the present in some way, from early settlements to westward expansion, from war and invention to civic achievements and cultural growth.”

Something else that this special Independence Day offers us is an opportunity to reflect on how successive technological revolutions have influenced our nation’s growth since its inception, and where the cutting-edge technologies of today are likely to carry us going forward.

America’s Tradition of Technological Revolutions

We’ve come a long way since 1776. Back in the days during which the Declaration of Independence was signed, the speed of information was constrained to how fast a horse could carry its rider, or how strong the winds were that could propel a ship across water.

Under such conditions, pens and ink were used to preserve ideas on paper that could take weeks to make its way from locations like Philadelphia to other parts of the colonies. With such technological limitations, human political organization was similarly constrained.

Over the last two and a half centuries, we have seen most of those limitations fall away, with new inventions advancing progress, and eventually being overtaken by even newer, bolder ideas and inventions. Our steam engines helped remove geographic constraints, only to be replaced by aircraft, automobiles, and conveyances propelled by electrical power.

Similarly, the telegraph helped collapse the imposition of time that once hindered communication; its successors, like radio, the telephone, the Internet, Smartphones, and a host of other mobile communications technologies, have now placed instantaneous global communication at our fingertips.

And now we are on the cusp of another great American technological transition: one that very likely will rival any that came before it.

The Rise of Artificial Intelligence

It is difficult to even compare artificial intelligence to any other potentially revolution-inducing technology in our nation’s history. As America turns 250 and we look back on the progress that has brought us to the present day, one must also wonder how history will look back on the advent of this technology: will we recognize the implementation of AI as another innovation that breaks significant barriers that constrained human achievement, as time and geography once did?

Or will the advent of AI be remembered differently? Science fiction affords us alternative scenarios that most of us are quite familiar with already, and the real possibility that AI could spell trouble for us in the years ahead remains ever-present. Where things go from here, understandably, has a lot to do with the question of what humans choose to use this technology for, and how we go about implementing it.

Yes, scientific progress is accelerating, and AI is helping with that. Discoveries are arriving faster not only because scientists are working harder, but because the tools they’re using—especially AI—are helping them achieve more, and increasing our productivity and overall capability to levels that dramatically exceed what humans alone can do.

From the design of new proteins in the lab and the identification of obscure exoplanets within mountains of astronomical data, to the acceleration of materials science and a range of other fields, much of what we are seeing AI help us achieve right now bears the promise of a brighter future. But should that hopeful vision for a better future be taken for granted?

There are obvious reasons for caution, since virtually every major technological revolution brings not only opportunities, but also disruption. New sources of technology replace old ones, and thereby require new skills to be leveraged. The result of this obsolescence often extends to those in the workforce whose expertise once propelled these predecessor technologies; once the technologies have fallen out of use (sometimes with remarkable speed), the human workers once tasked with building them are left having to find new professions.

Myriad examples of similar past technological scenarios exist that encourage such concerns. Nuclear physics gave us clean energy, but also nuclear weapons; the internet connected billions of people—and each day, it enables the spread of misinformation into our homes, along with the potential for unwarranted surveillance and cybercrime.

AI will almost certainly follow a similar pattern to every other major technological revolution that America, and the world at large, has ever seen. So the question isn’t one of whether it will change our society: we already know the answer to that.

The question here has more to do with how we will use this technology, and what we will allow it to do for us—and to us—as it progresses.

Palantir CEO Alex Karp’s Interesting CNBC Interview

To conclude on a somewhat odd, yet also an extremely relevant note in the context of what we’re discussing here, some interesting exchanges aired recently on CNBC’s “Squawk Box,” during a live segment featuring Palantir CEO Alex Karp.

Anyone who watches this will understand both the relevance, as well as my choice in characterizing it as “odd,” given the strange, rambling nature of Karp’s interview (admittedly, some have been a bit less gracious in how they’ve characterized the recent appearance).

Rather than discussing Palantir and Nvidia’s recent work for the United States government in assembling its new AI infrastructure, Karp appeared to have something else on his mind: the looming prospect of a financial bubble underlying the current boom in AI technology.

“Something has gone completely wrong,” Karp said at one point during one of the rambling exchanges, where he appeared to be addressing the token model currently employed by leading AI companies amid rising costs, as industry leaders continue to seek returns on investment.

“The basic view among enterprises in this country is I’m going to chillax and waste my time with tokens,” Karp said. In another portion of the diatribe, Karp aired his concerns about how current AI models have been “irresponsibly” oversold, which he called “dangerous for everyone, which is why I can give [AI] to all your adversaries but I can’t give it to the Department of War, or I can’t safely give it to an enterprise in this country, without being certain that the Alpha of that business could transfer to this model tomorrow, i.e. I have no business, no job.”

When chided by host Becky Quick for sounding angry, Karp shot back that “This is the voice of American business that is being channeled through me.”

“Are we really going to outsource the battlefield of this country to the consensus view in Silicon Valley?” Karp also said at one point. “That is effing insane.” The entire segment can be watched here.

Uncertainty is Our Business

Although Karp’s interview was odd, to say the least, the Palantir CEO raises some important points, and as evidenced by his demeanor during the CNBC segment, much of what he discussed appears to be weighing heavily on him.

It would be safe to say that he’s probably not the only one in Silicon Valley right now experiencing a degree of unrest and uncertainty over such issues, as the current situation with AI technologies in America and around the world progresses onward into uncertain territory.

Fortunately, America’s history shows that a major driving factor in its progress has been the conviction that the next horizon is worth pursuing, even when it’s uncertain.

Yes, the unforeseeable consequences of these nascent technologies, like AI, can be sobering at times.  While it seems inevitable that the same driving forces that have driven past industrial revolutions will also drive humans to build smarter, and increasingly more powerful machines, hopefully, we will also remember that wisdom is required in knowing how to use them.

If we can do that, then perhaps America’s progress can continue for another 250 years, and the technologies we are innovating in the present day can indeed help us to build a brighter future for tomorrow.

Here are the top stories we’re covering right now…

New research is revealing possible links between one of the most enduring cosmic mysteries—dark matter—and the existence of a “hidden” fifth dimension.

Dark matter is widely believed to exist according to several leading cosmological theories, although this nonluminous material remains invisible through direct detection. However, its presence can be inferred through the gravitational influence this mysterious form of matter has on the surrounding universe.

Now, according to researchers at the University of Sheffield, one reason dark matter may have remained so elusive involves the possibility that it exists within a “hidden” dimension—a concept that has gained traction in past research.

The Sheffield team’s recent look at this possibility, detailed in a study published in Physical Review D, takes the concept one step further by introducing a new potential framework that could help reveal clues to the behavior of dark matter, as well as why astronomers have had such a hard time detecting it.

A Dark Secret Lurking in a Hidden Dimension?

In their new research, the Sheffield team says that dark matter may be lurking within a hidden dimension accompanied by dark photons, a variety of particles among those which physicists call “hidden sector particles,” and which are believed to represent potential force carriers for dark matter.

Due to the specific geometry present within this hidden dimension, a phenomenon known as dark matter resonance may occur, where dark photons align in specific arrangements.

“Dark matter resonance is already known to be a powerful idea,” according to Yu-Dai Tsai, Ph.D., a Royal Society Dorothy Hodgkin Senior Research Fellow at the University of Sheffield and one of the new paper’s coauthors.

Tsai adds that the concept has “the potential to change our understanding of how dark matter was produced in the early universe and how we search for it today,” although reconciling it with our current understanding of dark matter has presented issues for researchers in the past, which include questions about its specific origins.

“Many previous resonant dark matter models have treated the resonance as an assumption,” Tsai recently said in a statement. “[Our team’s] work gives a possible deeper origin for it: The resonance may come directly from the geometry of hidden dimensions.”

Unlocking Dark Matter Resonance

According to Tsai and his co-author, Taegyu Lee, understanding dark matter resonance more fully could hold significant implications for unlocking new clues about how matter behaved at early stages in our universe, and why that may differ significantly from what astrophysicists see occurring right now.

“This resonance can make dark matter interactions much stronger at crucial epochs in cosmic history,” Tsai says. “Crucially, the model allows for these strong interactions in the past while still explaining why dark matter appears so inert and hard to detect today.”

Although Tsai concedes that the concept of dark matter resonance has been explored in the past, unlike previous studies, the Sheffield duo’s new work suggests that dark matter may essentially be “in tune” with conditions in a hidden fifth dimension already, arising naturally from its innate mathematical structure.

Tsai says this approach toward understanding dark matter, if correct, “would represent a profound advance in humanity’s knowledge of the cosmos and what it is made of.”

A New Approach Toward Unraveling Dark Matter’s Mysteries 

Fundamentally, the team’s findings point to promising new ways physicists may be able to explore the underlying mysteries of both dark matter and the possibility of additional dimensions in which it may operate.

“Our research gives physicists clear new targets in the search for dark matter,” Tsai says, “while connecting two of the biggest ideas in fundamental physics: the mystery of dark matter and the existence of hidden dimensions.”

The recent study, “Naturally resonant dark matter from extra dimensions,” by Yu-Dai Tsai and Taegyu Lee, appeared in Physical Review D on July 8, 2026.

As Christopher Nolan’s The Odyssey arrives in theaters, archaeologists working off the western coast of Greece say a real-life cult site devoted to the legendary story’s hero has been uncovered.

Local traditions had long told of a stony hilltop on the Greek island of Ithaca that had once been home to a shrine to Odysseus, the legendary Greek king of the isle and main protagonist in Homer’s famous poem.

Now, after close to two decades of archaeological work on the island that served as home to the fictional king in Homer’s epic literature, archaeologists say they have uncovered the most compelling evidence yet that a genuine historical cult site had existed there, dedicated to the famed hero of The Odyssey.

An Ancient Cult Site Devoted to Odysseus

Researchers with the University of Ioannina recently revealed the discovery of new inscriptions and artifacts supporting the existence of a cult element devoted to Odysseus, uncovered at the ancient complex at Agios Athanasios, which had been a public sanctuary devoted to the worship of Homer’s famous hero during the Hellenistic and early Roman periods.

According to a statement released by the Greek Ministry of Culture, the building complex is characterized by a series of robust structures located on terraces, which involve several monumental elements featuring carved architecture and niches for what appear to have been votive offerings or inscriptions, all of which point to its use as a cult site.

Yannos Lolos, one of the project’s lead archaeologists, recently told ArtNet that the site’s role was revealed partially through a reexamination of existing materials found there, which helped reveal what he calls “new and strong inscriptional evidence” linking the site to Odysseus.

Bronze Bust and Inscription Discoveries

Among the most important discoveries at the site were a small bronze bust of Odysseus dating to the first or second century C.E., as well as a roof tile fragment which bore an inscription that reads, “to Odysseus.”

However, an even more compelling discovery involved a second stamped roof tile inscribed with the hero’s name but appearing in the Greek genitive case; this is significant, since it indicates ownership, thereby identifying the sanctuary as “belonging” to Odysseus.

Based on current evidence, organized cult worship is believed to have begun at the site by around the late fourth century B.C.E., which places its use at around 500 years after Homer composed his famous epic poem, and almost a full millennium after the legendary events the epic describes.

The physical sanctuary itself was built onto a massive natural rock formation, and remnants of the ancient structure include a primary tower, a large oblong building, and terraces which were carved directly into the underlying bedrock.

Excavations over the last several years have also revealed the site’s deeper history, which points to evidence of earlier Mycenaean occupation during the 13th and 14th centuries B.C.E., at which time the site had likely served as a strategic center overseeing nearby harbors and local water resources.

A Discovery with Legendary Significance

In a statement, the Greek Ministry of Culture said the two new engravings arrives “in combination with the other available data, to document the development of a prominent public complex at the site,” which it said help to establish the “major role in the religious, social and possibly political life of the Ithacians of the Hellenistic-early Roman periods, but also with a broader pilgrimage character.”

The recognition of this ancient cult site only adds to the existing evidence that already supported worship of Odysseus on Ithaca. Past discoveries have revealed ancient coins depicting the hero, found near ritual offerings at Ithaca, which were also linked to cult activities. However, the identification of the sanctuary offers the most conclusive archaeological evidence to date that Homer’s legendary hero had been the cult’s focus.

Of course, these discoveries fall short of establishing Odysseus as a true historical figure, and most scholars agree that Odysseus was a fictional character born out of traditions that incorporated real places and events into their broader mythos.

However, in at least a few instances, the lines between myth and ancient history have been blurred—a famous example being Heinrich Schliemann’s identification of a site (originally discovered by British amateur archaeologist Frank Calvert, with his identification of the mound of Hisarlik) which helped reveal the archaeological reality behind the city of Troy, which had previously been considered a mythical location.

It was also reported last year that an archaeological discovery resembling the “labyrinth” from Greek mythology had been uncovered on Crete, in a discovery some have called “one of the most important archaeological finds” of the century.

Although the discoveries at Ithaca don’t establish Homer’s Odysseus as a historical figure in this way, they do confirm that centuries after The Odyssey was composed, inhabitants of Ithaca engaged in cult activities to honor the legendary king at a sanctuary on the island, which, according to legend, he once ruled.

Additional details about the site and discoveries made there in recent years can be found at the Greek Ministry of Culture website.

This week in science and technology news we’re covering at The Debrief: For decades, physicists have argued about Richard Feynman’s Sprinkler Problem, involving the question of how a reverse sprinkler would operate. Now we may finally know the answer… elsewhere, new studies reveal how breathwork may trigger psychedelic-like states, emotional breakthroughs, and psychological insights without drugs. Meanwhile, a stone sphere unearthed at an archaeological site in Azerbaijan is reportedly unlike anything previously documented in the South Caucasus.

Also, in an exclusive feature, University of Toronto bioethicist KM Bowman, Ph.D., writes for The Debrief about his firsthand experience with uncontacted indigenous tribes: “Through the haze stood a man. Barely clothed, carrying what appeared to be a weapon of some form, he remained motionless for only a few seconds before silently disappearing back into the forest.” In his essay, Bowman shares his experience and asks whether governments can protect “the uncontacted.”

Finally, here’s a look at more stories The Debrief is tracking right now…

An unusual find has been unearthed by archaeologists excavating a prehistoric settlement in Azerbaijan, who recently discovered a stone sphere they say is unlike any previously documented in the South Caucasus.

The mysterious spherical artifact, crafted from polished stone, was uncovered during excavations at Pasha Tepe in Azerbaijan’s Jalilabad district, and raises new questions about Neolithic technology, trade, and ritual practices.

A Mysterious Stone Sphere Resurfaces

Excavations at the site are currently being undertaken by a team led by Vafa Mahmudova of the Institute of Archaeology and Anthropology at the Azerbaijan National Academy of Sciences.

The unusual find, which measures approximately 4 inches in diameter and weighs a little more than four pounds, immediately stood out among the items the team had uncovered during excavations. They describe the object as potentially being among the most significant polished stone artifacts associated with the region’s Neolithic period that archaeologists have recovered to date.

“The stone sphere is of particular scientific importance because of both its manufacturing technology and its possible function,” Mahmudova recently told the Azerbaijani news site Report.

“It offers a new source of information for understanding connections between the Levant, Anatolia, and the South Caucasus during the Neolithic period,” he added.

The carefully crafted sphere stands out for its remarkably smooth surface and nearly perfect shape. Unlike many prehistoric stone objects, however, it bears no perforations, impact marks, or other modifications that might reveal how it was used.

Unlike Past Discoveries

Mahmudova says that presently there is no similar object that has yet been identified in archaeological records from the South Caucasus, making the discovery potentially unique.

Presently, the techniques employed in crafting the object remain unclear, as well as what its function might have been. Mahmudova and his colleagues believe that understanding the reasons for its creation could potentially offer valuable new insights into cultural connections linking the South Caucasus with Anatolia and the Levant during the Neolithic period.

What Was Its Purpose?

A range of theories about the object’s purpose have been put forward, which include that it may have been a ceremonial object used for ritual purposes. More utilitarian possibilities include that it may have been a sort of standardized weight, although neither theory can presently be confirmed based on available data.

Presently, Mahmudova and his colleagues hope to compare the artifact to other similar discoveries, and by drawing from specialists and additional scientific analyses, obtain a better idea of the manufacturing processes behind its creation, and what purpose it might have served.

Additional Discoveries

As excavations at Pasha Tepe remain underway, Mahmudova and his colleagues also say they have recently uncovered sections of a medieval ceramic pipeline, which they say may have served as a component of an ancient water management or drainage system.

Additional surveys at nearby archaeological sites, including the Chalcolithic site Alikomektepe, have offered additional clues that are helping archaeologists reveal clues about the ancient ways of life in the region, according to Heritage Daily.

Future studies involving the curious stone sphere Mahmudova and his colleagues unearthed at Pasha Tepe will hopefully shed additional light on the technological capabilities and cultural traditions of some of the earliest farming communities in the South Caucasus. With any luck, they may also find additional clues to the purpose of an artifact that, for the time being, remains unlike any previously discovered in the region.

Engineers have developed a new robot that can swim underwater, then rise to the surface and take flight, in an aerial-aquatic feat that mimics some of nature’s most formidable fliers and swimmers.

Developed by researchers at the Massachusetts Institute of Technology (MIT) and the Swiss Federal Institute of Technology Lausanne (EPFL), the new robot’s capabilities could help launch a new generation of aerial-aquatic exploration vehicles.

Dubbed the “Flapping-Wing Aerial-Aquatic Vehicle” (FAAV), this lightweight robotic platform weighs less than 300 grams and can transition seamlessly between water and air with its very flexible flapping wings. Now, the team’s findings, published in the journal Science, could help scientists better understand how diving birds, which include puffins, petrels, loons, and gulls, are so adept at navigating two vastly different environments.

Such capabilities, the team says, could also pave the way toward advanced drones in the coming years that could transform ocean research.

Inspired by Diving Birds

Departing from conventional modern designs employed for aircraft or underwater vehicles, the team based their design on diving birds, which evolved to fly over water, then plunge beneath the waves to hunt for food, before surfacing and resuming flight.

One problem when it comes to replicating these abilities in robots involves the density of water, which is around 1,000 times denser than air. Because of this, the engineering team had to carefully balance the flexibility of the robotic wings in their design, along with flapping frequency, tail angle, and other factors that allowed the robot to move efficiently through both environments without requiring propellers or separate propulsion systems.

Finding the Sweet Spot for Transmedium Travel

Experiments were undertaken by the team in the lab and in Switzerland’s Lake Geneva, and helped the team determine that the robot achieved best performance with medium-sized wings that flap at approximately five times per second. Under such conditions, the robot was able to swim one meter per second, then by pitching upward at a 70-degree angle, it could break through the surface, and continue this same movement to propel itself through the air.

Although the robot still has some limitations compared to the avian examples that inspired it, interestingly, it does appear to have one advantage: unlike diving birds, which paddle using their feet to achieve aquatic launches into the air, the new robot has no such requirement, and can transition from water to air relying only on its wings and adjustable tail.

Future Drones with “Aerial-Aquatic” Abilities

In the future, drones equipped with such capabilities could be leveraged to monitor marine ecosystems in a variety of ways. The team also says it could help to observe environmental concerns, such as water near glaciers or offshore infrastructure, or even collect data from hazardous locations that are either too difficult or simply too costly for ships to reach.

“Our dream vision is for oceanographers, marine biologists, and members of coastal communities to launch this robot from a boat, or from shore, and it would fly close to the area of interest, such as an iceberg or a port facility, or over a pod of whales,” according to Raphael Zufferey, assistant professor of mechanical engineering at MIT.

“It would dive into the water to take a measurement or collect a sample, and fly back to deliver the data at a fraction of the cost of traditional methods. Then it could go back out to dive for more,” Zufferey recently told MIT News.

Drawing from movements in nature influenced by evolution, the researchers hope their bird-inspired design may eventually help scientists by introducing cost-effective, but formidable new tools to help obtain information from some of the most challenging environments, all with help from robots that can do what only nature’s diving birds could once achieve.

The achievement is detailed in a new paper, “Leaping out of the water: aerial-aquatic locomotion with flapping wings,” which appeared in the journal Science.

An unusual phenomenon that has been recognized around the world for more than a century has finally been resolved: what are the origins of the distinctive, stair-like ridges that form on steep hillsides?

These features, known as “terracettes,” have long puzzled scientists, and the question of how they form has attracted some of history’s greatest minds, including Charles Darwin.

The famous naturalist described these features as “Little horizontal ledges, one above another,” which he said had been “observed on steep grassy slopes in many parts of the world.”

According to Darwin, the formation of terracettes had “been attributed to animals traveling repeatedly along the slope in the same horizontal lines while grazing,” although he adds that “Professor Henslow (a most careful observer) told Sir J. Hooker that he was convinced that this was not the sole cause of their formation,” with the implication that these curious, structured features on steep hills might have geological origins, rather than those attributable solely to biology.

Now, researchers may finally have an answer to this pastoral riddle that baffled the likes of Darwin more than a century ago, settling the scientific debate over their origins.

Solving the Mystery of Terracettes

Benjamin Seleb, the lead author of a new study detailing the findings, said the mystery of terracettes first attracted his attention in 2024 after he observed them firsthand during a hike in the Alps.

“I suspected the numerous grazing cows—hard to miss with their clanking bells—had something to do with it, and was already sketching out how I would model their movement before the hike was over,” Seleb says.

“It wasn’t until I got back to my hotel and started digging into the topic that I learned about the contested origins of these terracettes,” Seleb adds. “With my curiosity piqued, I got to work building a simple model to ask whether grazing animals really could reshape mountains.”

According to Seleb and a team of collaborators from the Georgia Institute of Technology and the BioFrontiers Institute at the University of Colorado Boulder, computer modeling was employed to reshape hillsides into these distinctive “stepped” formations. The findings reveal that the most likely explanation is that repetitive pathways followed by grazing animals such as sheep and cattle produce remarkably ordered landscape patterns over time.

Simulating ‘Chaos’ to Solve a Mystery

To test their hypothesis, the research team simulated the movement of individual animals across steep slopes. For their analysis, they also introduced a few rules, which revealed that the “virtual grazers” preferred traversing hillsides in long, horizontal pathways that form gradual inclines. This makes sense, since it is a method of ascent that requires less energy, and humans have also traditionally employed similar approaches (think of mountain trails, which, rather than ascending straight uphill, follow longer sloping inclines and switchbacks where directional changes are necessary).

With each simulated footstep, soil and vegetation become compacted, producing subtle alterations to the terrain over time. As these pathways form, animals over successive future generations are thereby encouraged to follow similar routes, and with time, the familiar terraced patterns emerge.

“People have argued about terracettes for over a century,” says Professor Saad Bhamla, one of the study’s co-authors and leader of the Bhamla Lab of Extraordinary Organisms, which describes its efforts as work that “seeks to understand how organisms do amazing things.”

“Some say [terracettes] are purely geological, just slow soil creep and slumping,” Bhamla recently said. “Others say animals create them, and the standard criticism for the animal-origin camp is that the animals wander around randomly, so how could they ever carve something this regular?”

“What we show is that they can and that this regularity emerges out of that chaotic, random movement, not in spite of it, through the back-and-forth between the animals and the ground they’re chewing up with their mouths and packing down with their feet,” Bhamla adds.

Complexity from Simple Movement

Bhamla and his team say their research offers another example demonstrating how complex natural landscapes can emerge from simple, uncoordinated behavior, involving a process known as stigmergic feedback. This involves organisms that gradually reshape their shared environment over time.

The result of their work is an answer to a mystery that has persisted for many generations, and not only that, but also a pathway toward understanding the various ways animals influence landscapes more broadly.

The team’s findings were detailed in a new paper, “Moo-ving mountains: grazing agents drive terracette formation on steep hillslopes,” which appeared in Journal of the Royal Society Interface.

The United States Department of War (DOW) released its latest collection of imagery and other materials related to unidentified anomalous phenomena (UAP) on Friday.

The fourth official release under what the DOW has dubbed the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE), the latest tranche of files includes several new previously unseen U.S. military videos depicting unidentified aerial objects acquired by the Pentagon’s All-domain Anomaly Resolution Office (AARO).

“Today, the Department of War is publishing the fourth release of declassified and historical Unidentified Anomalous Phenomena (UAP) files as part of the Presidential Unsealing and Reporting System for UAP Encounters (PURSUE),” said Assistant to the Secretary of War for Public Affairs and Chief Pentagon Spokesman Sean Parnell in a statement.

“The collection continues to be housed on WAR.GOV/UFO, and the Department will release additional files on a rolling basis,” Parnell said.

As with previous releases, the new videos leave much to the imagination; in most cases, they show small blurry objects captured with multi-sensor electro-optical targeting capabilities from fighter aircraft or UAVs, and in some cases, imaging systems on board civilian aircraft. In addition to the new imagery, several historical documents from as early as the 1940s were included with the release, the majority of which were previously made available in past releases by various U.S. government agencies.

Here is a look at a few key takeaways from the latest batch in the Pentagon’s ongoing release of UAP-related materials.

A Deeper Look at the Latest PURSUE UAP File Release

One series of historical NASA images included with the new PURSUE release originates from the 1996 STS-80 mission. The entry on the DOW’s site, “NASA-UAP-D030, STS-80 Unidentified Object Image 1, 1996,” features photographs obtained by astronauts aboard the Space Shuttle Columbia at the time, which convey a small triangular or cone-shaped object.

“During STS-80, between November 19 and December 7, 1996, astronauts aboard Space Shuttle Columbia captured a series of three images of an unidentified object in low-Earth orbit. In the first photograph, the object is visible near the center of the frame, to the right of the limb of the Earth,” a caption accompanying one of the images states at the DOW website.

It is unclear what the object in the photograph may be, although it is worth noting that several observations of allegedly unusual phenomena occurred during STS-80, which included the imagery captured of grainy luminous shapes from the spacecraft’s backward-facing cameras. The most common interpretation of these objects is that they were ice particles outgassed from the spacecraft, whose highly reflective surfaces could produce the optical effects captured from the space shuttle’s cameras, especially in such low-light conditions.

DOW-UAP-PR030, Unresolved UAP Report, Middle East, 2023: In this video, “Two areas of contrast transit the sensor field-of-view. The first enters the field-of-view from the bottom right and exits from the top edge of the frame. The second, relatively smaller area of contrast enters from the top and exits the bottom of the frame.”

The unusual shape of the object first seen entering the frame from the bottom of the screen could potentially be the result of a sensor artifact, similar to past videos released by the DOW, where the starlike appearance of refraction spikes emanating from an object (as also seen in this example from the most recent release) had been misinterpreted by some as being the literal shape of the alleged UAP.

DOW-UAP-PR108, Unresolved UAP Report, Western United States, 2020: This footage, reportedly collected over the Western United States in 2020, is notable (if for no other reason) due to its similarity to the famous “Tic Tac” imagery from 2004, captured by F/A-18 pilot Chad Underwood off the Baja California coast. Apart from that superficial similarity in appearance, the footage—like others from recent PURSUE releases—provides little additional context, and it is unclear what the object (seen below) may be.

Several other examples of imagery included with the fourth PURSUE release depict objects apparently engaging in flight at high speeds, such as an object appearing in “DOW-UAP-PR112, Unresolved UAP Report, Eastern United States, 2019” where the observer reportedly described the object in question as exhibiting “flight characteristics unlike anything [the observer] had seen in 28 years for the U.S. Air Force and U.S. Navy.”

Other objects appearing in videos included with the newest release, such as the UAP in “DOW-UAP-PR116, Unresolved UAP Report, Atlantic Ocean, 2020,” include descriptions from the observer that note an object with a “darker, maroonish color, approximately 12-15 feet in height” that was “travel[ing] with the wind,” did not “maneuver or change direction,” and appearing similar to a “large, somewhat deformed balloon.”

We would have to agree with the witnesses’ assessment in the case: the flight dynamics of the object in the accompanying video (seen above) are indeed very consistent with an inflatable object, albeit possessing an odd shape (it is also possible this object may be a cluster of smaller balloons). The same can be said of other examples in the new releases, where, in some instances, dangling payloads beneath what are obviously balloons are clearly discernible in the purported “UAP” videos.

Clarity Remains Elusive, but More Releases to Follow

To date, none of the videos or other documentation made available at the DOW website as part of its PURSUE releases provides clear examples of any objects attributable to unknown aircraft, or objects exhibiting unusual or advanced technologies.

In his statement on Friday, Parnell said the DOW and its agency partners “are actively working on the next release of UAP files,” which can be expected to appear on the DOW website in the coming weeks. In the meantime, all of the existing four releases of UAP imagery and documentation can be found on the DOW’s PURSUE page.

Residents of Forest Beach in Queensland, Australia, were recently urged by one local business to “do the smart thing” and “panic buy” after unusual objects found in the area were likened to the remains of a crashed UFO.

The amusing alien wreckage references followed a surprising discovery in the coastal community: a collection of six odd metallic spheres found along the community’s beaches over the weekend.

Although many mystery objects that are found on beaches have Earthly origins, that wasn’t the case in this instance: according to Australian Space Agency officials, these mysterious metallic spheres actually did fall from space.

The Mystery Spheres of Forrest Beach

The mystery began on July 5, when Queensland Fire Department personnel responded to reports of unusual objects spotted by area residents along the nearby shoreline.

“Queensland Fire and Rescue crews are continuing to assist partner agencies following the discovery of several potentially hazardous objects around Forrest Beach in North Queensland,” the agency wrote in an update that appeared on its official Facebook page.

“Specialist QFR Scientific teams have safely secured a number of the items throughout the weekend and remain on scene continuing their work,” the statement read. “A 50-metre exclusion zone is still in place.”

“The nature and origin of the debris are still being investigated,” the Queensland Fire Department statement added.

The following day, the Australian Space Agency confirmed the outer space origins of these objects, according to The New York Times, although with one caveat: while the curious spheres fell from space, their deeper origins are here on Earth, having likely been related to debris from a rocket that recently reentered from orbit.

“The recovered objects appear to be pressure vessels from a space launch vehicle,” according to a statement released by the Australian Space Agency that said the metallic spheres were “consistent with debris from a foreign rocket body,” though offering few additional details about the objects and their specific origins.

The suspected pressure vessels would have been used as storage containers for substances used during the launch phase, or possibly while in orbit.

Space Debris Found in Australia

“The majority of returning space objects either arrive back in a controlled manner to a specific location on Earth, or burn up in the Earth’s atmosphere,” the Australian Space Agency states on a page on its website that discusses space debris that may be discovered in Australia.

“Some objects may survive uncontrolled re-entry, making it harder to predict where the debris may fall,” the FAQ page states. “While any space debris that survives re-entry is most likely to land in the ocean or in remote locations, the initial discovery of space debris on Australian territory may be by members of the public.”

According to officials with Australia’s National Emergency Management Agency, there was no risk posed by the objects found at Forrest Beach, although the area around the discovery site was temporarily closed while officials descended on the area to test for any signs of contamination from potentially volatile substances.

Australia Isn’t Alone

Debris suspected of originating from spacecraft has made its way to Australia in the past. One large example discovered by residents in northeastern Australia four years ago was determined to have belonged to part of a SpaceX Dragon spacecraft.

Australians aren’t the only ones making such discoveries. In 2024, NASA confirmed that an unusual object found on a remote property in Western North Carolina had also been SpaceX debris from one of the company’s Dragon capsules.

The Debrief was one of the first outlets to identify that object as possible SpaceX debris, after noting similarities to a confirmed portion of the trunk section from a Dragon capsule used during the SpaceX Axiom 3 mission that survived reentry over Saskatchewan on Feb 26, 2024, and was later discovered by a farmer on his property.

Our Fascination with Mysterious Metallic Spheres

Last year, similar claims involving the alleged recovery of a mysterious metallic sphere were reported in March near Buga, Colombia. Researchers who studied the object, which was allegedly observed passing through the sky before it was recovered from an area of thick undergrowth, claimed the object had “no welds or joints,” and that it featured unusual symbols on its surface.

The origins of the Buga mystery sphere remain undetermined, with some suspecting that, rather than space debris in this instance, the object may simply have been a hoax.

Such stories highlight our fascination with mysterious metallic spheres, which is nothing new, especially when it comes to mysterious sightings of unusual objects. During the height of the Second World War, The New York Times carried a news brief in its December 14, 1944 edition, which described observations by U.S. pilots involving unusual spherical objects seen over Europe.

“A new German weapon has made its appearance on the western air front,” the short Times article reads. “Airmen of the American Air Force report that they are encountering silver colored spheres in the air over German territory.”

“The spheres are encountered either singly or in clusters,” the brief concludes, adding that “Sometimes they are semi-translucent.”

In an April 2023 Senate Subcommittee on Emerging Threats and Capabilities hearing, Dr. Sean Kirkpatrick, at the time serving as the inaugural director of the Pentagon’s All-domain Anomaly Resolution Office, told lawmakers that small spherical objects accounted for a majority of the reports it receives involving what the U.S. military now calls unidentified anomalous phenomena (UAP), historically known as UFOs.

More Space Debris Could Be Found

While Australian officials have confirmed that the objects discovered at Forrest Beach aren’t evidence of visitors from space, they have nonetheless advised that it is possible additional debris could be found, and locals who may find such materials have been advised to alert the Australian Space Agency.

“Do not handle the debris,” the Australian Space Agency states on its website. “Space objects are built from a range of materials that may be hazardous. They should only be handled by appropriately trained and equipped professionals.”

Residents in Australia who discover possible space debris are advised to contact the country’s space agency using the official contact page available on its website.
