Sweden could become an important source of rare earth elements needed for magnets and green technologies. Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits. They will then develop magnets using those naturally available combinations, potentially reducing pollution, waste, and reliance on China.

A newly identified fossil ape from northern Egypt is reshaping ideas about where the ancestors of modern apes first emerged. Analyses place it closer to living apes than any known East African species of the same age, pointing to North Africa and the Middle East as a possible birthplace and crossroads for the ape lineage that eventually produced gibbons, orangutans, gorillas, chimpanzees, and humans.

Fossils discovered in Japan more than two decades ago have finally been identified as a new genus and species of giant salamander. Limnospondylus ajimuensis lived around 3.5 million years ago in a warmer, wetter Kyushu and may have reached 1.1 meters in length. Its discovery hints that many more unknown giant salamanders could be hiding among fossils previously given the wrong classification.

Researchers in the Gulf of California have documented a dramatic orca behavior never described before. In two separate encounters, one orca gripped a dead sunfish by the fin while another charged into it at high speed, blasting the carcass into thousands of pieces.

A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume production could soar, creating a sweeping transformation of what the world grows and eats.

Scientists may be able to reliably forecast Antarctic ice loss through the middle of this century, offering governments a vital head start on sea level rise. After that, unstable ice retreat could accelerate dramatically, making the future much harder to predict.

Researchers found that specific brain circuits help decide which jobs bees perform as they age. When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties. The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden inside each bee’s brain.

Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the devastation.

Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the Eyes of K’gari.

China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnetic shield.

Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric contact.

Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs. All four infected whales showed serious digestive damage, including inflammation, ulcers, scarring, and parasite infestations, although the bacteria were not confirmed as the cause of death.

Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were young. The upright pose may have helped them reach treetops, frighten predators, or impress potential mates.

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is closely connected to other major planetary threats, including warming, pollution, biodiversity loss, and ocean acidification.

Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia's marsupials all came from a single straightforward ancestral lineage.

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.

Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal layers cut through by vast swarms of vertical magma channels, along with unusually slow seismic waves suggesting that deep-rising magma chemically altered the plate itself.

Tiny plastic particles in drinking water may be doing more than contaminating the environment. New research suggests nanoplastics can actually help harmful bacteria survive by strengthening the slimy biofilms they form inside water systems. These tougher biofilms become more resistant to disinfectants, making them harder to remove and potentially increasing public health risks.

A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia. By calculating the koala's mutation rate for the first time and analyzing hundreds of genomes, researchers discovered that every living koala traces back to a small group that survived extreme climate shifts and later repopulated eastern Australia.

Researchers have created self-destructing living plastic that uses engineered bacteria to completely break itself down when activated. The material degrades in just six days without creating microplastics, offering a potential new solution for single-use plastic waste.

An ancient sea worm may hold the secret to a whole new category of natural materials. Its jaws combine proteins and metal ions in a way that gives them metal-like strength and unusual mechanical behavior, yet they still differ from traditional metals. Researchers believe these "bio-metals" could open new directions in materials science while revealing just how sophisticated nature's designs can be.

Scientists have identified a hidden feedback loop that may explain how Earth has regulated its climate for tens of millions of years. As sea levels rose and fell, they changed how much phosphate reached the open ocean, affecting marine life and the amount of carbon buried beneath the seafloor. That burial removed carbon dioxide from the atmosphere, helping cool the planet.

An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, offering a rare opportunity to study the disease as it develops naturally.

NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen from space. An astronaut aboard the International Space Station also photographed the bloom spreading through the Bosphorus, revealing swirling currents.

A 1,600-year-old mummy discovered in Egypt has revealed something archaeologists had never seen before: a fragment of Homer’s Iliad used during embalming. The papyrus was identified as part of the famous "Catalogue of Ships," one of the best-known sections of the ancient epic. Researchers say it is the first archaeological evidence of a Greek literary text being intentionally incorporated into the mummification process, adding a fascinating new chapter to the history of both literature and ancient burial customs.

Humans are often described as the planet's ultimate "super-predator," but wild animals do not fear every human the same way. After analyzing three decades of research, scientists found that animals become much more alert and spend less time feeding when people pose a real threat, such as hunters or fishers. In contrast, tourists, researchers, and other non-lethal humans trigger far weaker and less predictable reactions.

A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still tadpoles, giving them a head start before the fungus can attack after metamorphosis. The study also uncovered a vast collection of previously unknown antimicrobial peptides that could someday inspire new drugs to fight infections.

Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use.

A major review found that people who consumed the most chili peppers had a substantially higher risk of esophageal cancer, though the evidence was less clear for stomach and colorectal cancers. Researchers emphasize that the findings show an association, not proof of cause and effect, and that more research is needed to determine whether moderate consumption carries similar risks.

The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely protected. That releases extra carbon dioxide into the atmosphere, potentially accelerating global warming.

A fossilized Edmontosaurus skull with a Tyrannosaurus tooth still embedded in its face has given scientists rare evidence of a dramatic predator-prey encounter. The discovery suggests the giant carnivore delivered an incredibly powerful face-to-face bite, offering new clues about how Tyrannosaurus hunted.

A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution before it becomes widespread.

Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal care followed different evolutionary paths. The project, completed in just days with help from public data, shows how citizen science is transforming biological research on a global scale.

Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate change.

Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expanding northward, where they prey on native insects, pollinators, and even small vertebrates while also reducing native mantis populations through deadly mating interactions.

Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese evolved from much more recent arrivals, revealing a far more dynamic evolutionary history than once believed.

A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close to the surface. Scientists are now watching closely to see if the eruption creates a new island, offering a rare opportunity to observe the birth of new land as it happens.

A next-generation pesticide designed to kill crop pests may also be interfering with the reproductive health of bumblebees. Researchers discovered that low-dose exposure to sulfoxaflor changed gene activity, especially in tissues involved in reproduction, raising concerns about long-term impacts on bee populations. Because pollinators are essential for about one-third of the world's food production, finding ways to protect them while controlling pests has become increasingly important.

Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma that are pushed upward through cracks created by shifting tectonic plates. If confirmed, Etna could belong to a rare fourth category of volcano, revealing that much larger volcanoes can form through processes previously associated only with small submarine eruptions.

A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more serious bites. The team also uncovered how the myth spread through decades of inaccurate news reports and misleading quotes from trusted sources.

A newly discovered Happy-Face spider in the Himalayas closely resembles Hawaii's iconic species but evolved independently, according to DNA evidence. Its mysterious smile-like markings, many color forms, and unexpected link to ginger plants have scientists eager to learn how the two distant species are connected.

Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a warmer future.

For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets left to reveal.

Researchers have cracked the code behind bacteria's ability to naturally manufacture multiple versions of powerful anti-cancer drugs. The discovery could make it much easier to engineer new cancer treatments inspired by nature, including improved versions of existing medicines.

DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.

Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.

Claims that Neanderthal men "preferred" Homo sapiens women may make for catchy headlines, but the underlying research does not actually show prehistoric romance. The genetic evidence only points to an uneven pattern of DNA inheritance, which could have been shaped by biology, migration, or social organization. Archaeological evidence suggests Neanderthal groups may have followed traditions where women moved between communities, opening the door to far more complicated explanations than simple attraction.

Scientists have finally solved a nearly 30-year-old mystery surrounding two unusual molecules found in rye pollen that once showed an intriguing ability to help animals fight tumors. By determining their exact 3D structures, researchers have unlocked the blueprint needed to investigate how these natural compounds interact with the immune system and which parts may be responsible for their cancer-fighting effects.

Researchers discovered that artificial streetlights can trap thousands of woodlice in mesmerizing circular "death spirals" never before seen in the wild. The surprising finding suggests that light pollution may be unintentionally altering the behavior of even the smallest ground-dwelling animals.

Scientists have uncovered a hidden weakness beneath the Pacific Ocean that helps explain why Japan’s catastrophic 2011 earthquake and tsunami became so devastating. By drilling deeper into the seafloor than ever before, researchers discovered a thin, slippery layer of ancient clay that allowed the massive rupture to race all the way to the ocean floor, triggering enormous seafloor movement and a powerful tsunami.

A stunning fossil discovery shows that ancient bees used the empty tooth sockets of mammal bones as tiny nests after owls scattered the bones across a cave floor 20,000 years ago. It's the first known evidence of bees nesting inside animal bones, revealing an astonishingly creative survival strategy.

Scientists have uncovered new evidence that fireworks can pollute both the air and water in ways that extend beyond the visible smoke. The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase people's exposure to air pollution during major celebrations.

A new study found that not all geoengineering ideas are created equal. Brightening marine clouds over the eastern Pacific could dramatically weaken the El Niño cycle, triggering major changes to global weather patterns, while stratospheric aerosol injection left the system largely unchanged. Researchers say the results are a reminder that efforts to cool the planet could produce unexpected consequences if they are deployed without a full understanding of how Earth's climate works.

A pioneering climate scientist is challenging a U.S. government report that cited his research while reaching what he says is the exact opposite conclusion. Benjamin Santer and his colleagues say decades of satellite data clearly reveal the atmospheric “fingerprint” of human-caused climate change. Their new peer-reviewed analysis argues the report contains major scientific errors and should not be relied upon in climate policy decisions.

The rhythm of human laughter appears to have deep evolutionary roots shared with chimpanzees, bonobos, gorillas, and orangutans. That ancient pattern may offer one of the clearest clues yet to how the vocal control needed for human speech gradually evolved.

Researchers have uncovered an unexpected antiviral defense system in sea anemones that works very differently from the one humans use. The discovery suggests evolution developed multiple ways to combat viruses, challenging long-held ideas about how animal immune systems evolved.

Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils. Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilient. Greenhouse and field tests showed healthier plants and higher yields in salty conditions. The findings could lead to bio-based treatments that help farmers grow crops on land once considered too salty for agriculture.

Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads. Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material. If future studies confirm the roads are durable, the technology could help tackle both marine pollution and overflowing landfills.
