Researchers uncovered evidence that recurring, decades-long droughts likely made the site less practical by reducing access to the water needed to process large numbers of animals. At the same time, hunting groups were shifting toward larger, more coordinated operations that required dependable resources and specialized locations.

Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing they could use a mirror as a tool rather than simply reacting to a reflection.

In zebrafish, a coordinated pattern of activity spread across the brain several seconds before the animals approached another fish. A higher brain region called the pallium played a key role, and fish with stronger neural signals were generally more social.

Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium carbonate, a mineral that plays an important role in ocean health and carbon storage. For years, researchers believed fish handled this process on their own, but the new findings point to a hidden partnership between fish and microbes.

Birds deprived of these cells struggled to find their way home under overcast skies, indicating they rely on Earth’s magnetic field for guidance. The discovery could solve a decades-old mystery about animal navigation and reveal an unexpected connection between immunity and sensing the environment.

Scientists studying four isolated populations of British Wrens discovered that some island birds have grown astonishingly large — with the biggest St Kilda Wrens weighing more than twice as much as the smallest mainland birds. The research suggests these wrens are evolving independently, developing unique songs, appearances, and genetics that may eventually turn them into entirely new species.

Scientists believe it may be one of the largest bee aggregations ever documented and say the insects are crucial pollinators for apple orchards and other crops. The bees have likely lived there for more than 100 years, thriving in the cemetery’s undisturbed sandy soil.

Scientists have now discovered that the so-called Himalayan pit viper is not just one species, but actually five separate species — including three completely unknown to science until now. Tue, 26 May 2026 04:52:05 EDT https://www.sciencedaily.com/releases/2026/05/260526021953.htm https://www.sciencedaily.com/releases/2026/05/260526021950.htm A sweeping new study of wild snakes in the southeastern US has revealed a hidden health crisis slithering beneath the surface. Researchers found that many snakes are carrying multiple infections at once, with a dangerous fungal disease called ophidiomycosis — or snake fungal disease — emerging as one of the biggest threats. Pygmy rattlesnakes appeared especially vulnerable, frequently infected with both the fungus and a parasitic “snake lungworm.” Tue, 26 May 2026 07:29:57 EDT https://www.sciencedaily.com/releases/2026/05/260526021950.htm https://www.sciencedaily.com/releases/2026/05/260525000459.htm Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may have helped it gulp air and a light-sensitive organ linked to day-night rhythms.

A massive new evolutionary study shows these skin bones appeared independently in multiple lizard groups rather than coming from a single armored ancestor. Even more astonishing, Australian goannas lost this armor long ago — then evolved it back again millions of years later.

By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The findings could help conservationists identify safer new habitats and establish backup populations before disasters like bushfires wipe them out.

Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering.

The newly named Nagatitan chaiyaphumensis was a colossal long-necked sauropod that weighed around 27 tonnes and lived more than 100 million years ago. Scientists believe it may be the last giant sauropod ever to roam the region before rising seas transformed the landscape.

By analyzing traces of DNA floating in seawater from depths exceeding 4 kilometers, researchers identified 226 species ranging from deep-diving whales to strange fish rarely or never seen in the region before. Some of the creatures may even be unknown to science.

Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn’t flower size or specialized pollinators, but how quickly cactus flowers change shape over time. The finding overturns a long-standing idea dating back to Darwin and reveals deserts as surprisingly dynamic ecosystems where evolution is happening fast.

The special gene boosts production of a substance called high molecular weight hyaluronic acid, which appears to protect against cancer, reduce inflammation, and support healthier aging. The modified mice showed stronger resistance to tumors, healthier guts, and lower levels of age-related inflammation.

A chemical called bistrifluron prevents drywood termites from forming new exoskeletons during molting, killing entire colonies from within. In tests, it eliminated about 95% of termites while avoiding the toxic side effects of traditional fumigation. Researchers say the method could provide longer-lasting protection as termites spread into new areas.

By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mice, marking a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics.

Scientists discovered that hours after returning to land, the seals’ heart rates suddenly surge — sometimes doubling — as they recover from the intense physical stress of deep diving. The findings suggest that seals postpone much of their recovery until they’re safely ashore, likely flushing out lactic acid and rebuilding oxygen stores after days of nonstop diving and hunting.

Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors. Rather than altering the genes themselves, evolution modifies how they’re switched on and off. This discovery hints that life may evolve in more predictable ways than previously believed.

A katydid spotted glowing hot pink in Panama stunned researchers when it slowly transformed into green in just 11 days, perfectly mirroring the life cycle of tropical leaves that emerge pink before maturing. What once seemed like a rare genetic oddity now appears to be a clever survival trick, allowing the insect to blend in as its leafy surroundings change.

Researchers found that most modern crabs inherited this trait from one ancestor—and never looked back. The movement likely gave them an edge, helping them dodge predators with quick, unpredictable bursts. It’s a rare example of a behavior evolving once and then dominating an entire group.

Instead, the key difference may have been social connectivity—Homo sapiens formed stronger, more flexible networks that helped them survive environmental shocks. Neanderthals had connections too, but they were more fragile and regionally limited. This made them less resilient as conditions became increasingly unpredictable.

The tiny species, Cimolodon desosai, lived 75 million years ago and had traits—like a small body and varied diet—that likely boosted survival odds. Found in Baja California, the fossil includes rare skeletal remains that reveal how it moved and lived. Researchers believe its lineage helped mammals endure one of Earth’s deadliest events.

By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even after beginning to diverge around 120,000–135,000 years ago.

Researchers found that all sampled larvae were actually agave redworm moth caterpillars—not a mix of species as once believed. While the discovery clears up a long-standing mystery, it also raises concerns about sustainability. Growing demand for mezcal and edible larvae could put pressure on wild populations and the agave plants they depend on.

Scientists discovered that pike of all ages are eating more fish, with young pike increasing consumption by over 60%. Warmer water speeds up their metabolism, pushing them to hunt more. This growing appetite could spell trouble for struggling salmon populations.

A new study overturns that idea, revealing insect flight muscles weren’t constrained by oxygen after all. Their breathing system has plenty of room to expand, meaning oxygen alone can’t explain their giant forms. Now, researchers are searching for new answers—like predators or physical limits of their bodies.

By uncovering exquisitely preserved fossil jaws hidden inside rock, scientists revealed that early octopuses from the age of dinosaurs weren’t shy, soft-bodied drifters—they were massive apex predators, possibly stretching up to 20 meters long and crushing prey with powerful bites.

At McGraths Flat, scientists have uncovered fossils preserved in astonishing detail—not in typical rock like shale or sandstone, but in iron-rich sediment once thought incapable of such preservation. Tiny iron particles filled and captured entire cells, preserving everything from insect organs to fish eye pigments and delicate spider hairs.

Scientists warn it’s spreading quickly through U.S. forests, where it outcompetes native fungi and reduces biodiversity. In just a decade, it has appeared in more than 25 states, largely due to human cultivation and transport. Its silent expansion is now raising concerns about long-term impacts on forest ecosystems.

This tiny creature, Captorhinus aguti, reveals the earliest known version of the rib-powered breathing system used by modern reptiles, birds, and mammals — a crucial innovation that helped vertebrates thrive outside water.

Scientists had overlooked it for decades, assuming it was a common snake—until DNA analysis proved otherwise. Named after Laozi, it features striking differences between males and females, including bold stripes and eye colors. The discovery highlights just how many unknown species may still be lurking in well-studied regions.

This snake, now named the Ayeyarwady pit viper, puzzled researchers because it looks like a mix between two known species—sometimes resembling one, sometimes the other, and occasionally something in between. Initially suspected to be a hybrid, genetic analysis revealed it is actually its own distinct species.

New research shows these warm-bodied fish burn nearly four times more energy than cold-blooded species, forcing them to eat more while also struggling to shed excess heat. As oceans warm, this creates a dangerous “double jeopardy”: rising temperatures push them closer to overheating, while shrinking food supplies make survival even harder.

Scientists analyzed a tiny throat bone from the original fossil and discovered growth patterns showing the animal was already mature, not a juvenile giant-in-the-making. This smaller predator—about half the size of a full-grown T. rex—likely roamed alongside its famous cousin, adding a new layer of complexity to prehistoric ecosystems.

Reconstructed by a Virginia Tech student, it revealed a new species of early carnivorous dinosaur with unusual features never seen before. The fossil suggests some dinosaur groups were wiped out during the end-Triassic extinction, not just their rivals. It may represent one of the last survivors of an ancient dinosaur lineage.
