Why South Africa’s leopards shrank to half their normal size
A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after being isolated for r Read more
More trees can mean fewer birds, new study reveals
Trees planted to protect farmland from wind may not be the biodiversity boost many assume. In Japan’s wetland farming landscapes, shelterbelts benefited some birds but sharply reduced grassland and wetland species that need open space. Researchers found grassland bird abundance dropped by more than Read more
T. rex took 40 years to reach full size, scientists find
Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years. Read more
Lucy’s hunter revealed: Giant crocodile terrorized early human ancestors
A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human relatives. Read more
A legendary golden fabric lost for 2,000 years has returned
Researchers in South Korea have recreated the legendary “sea silk” once prized by emperors, using fibers from a clam cultivated in Korean coastal waters. They discovered that its famous golden shine comes from tiny protein structures that reflect light rather than from pigments or dyes. Because the Read more
The deadly tapeworm spreading across America has reached the Pacific Northwest
A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers discovered the parasite, Echinococcus multilocularis, in 37% of coyotes tested around Puget Sound—a s Read more
Deadly fungus and lung parasites are hammering wild rattlesnakes
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 on Read more
This prehistoric fish may explain how animals first walked on Earth
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 h Read more
Scientists say house cats could help unlock new cancer treatments for humans
Scientists have cracked open the “black box” of feline cancer in a landmark study that genetically analyzed nearly 500 cat tumors from around the world. The research uncovered striking similarities between cancers in cats, dogs, and humans — including shared cancer-driving genes tied to aggressive b Read more
Scientists use DNA from poop to save the world’s rarest marsupial
Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fun Read more
Scientists finally solve mystery of strange “golden orb” found 2 miles deep
A mysterious “golden orb” found more than two miles deep in the Gulf of Alaska left scientists baffled for over two years, sparking wild speculation about its origins. After an intensive investigation combining deep-sea expertise, microscopic analysis, and advanced DNA sequencing, researchers finall Read more
Scientists warn about golden oyster mushrooms sold in Florida markets
The golden oyster mushroom may be a culinary hit, but it’s becoming an ecological problem. 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 cultivati Read more
This 31-foot “terror croc” ate dinosaurs. Now it’s back
A massive, bus-sized “terror croc” that once preyed on dinosaurs has been brought back to life in stunning detail with the first scientifically accurate full skeleton of Deinosuchus schwimmeri. Stretching over 30 feet long, this ancient apex predator ruled the southeastern U.S. more than 75 million Read more
Scientists open 40-year-old salmon and find a surprising sign of ocean recovery
Old canned salmon turned out to be a time capsule of ocean health. Researchers found that rising levels of tiny parasitic worms in some salmon species suggest stronger, more complete marine food webs. Because these parasites depend on multiple hosts—including marine mammals—their increase may reflec Read more
DNA reveals two new bass species hidden in plain sight
Two new species of black bass have been officially identified after decades of confusion with similar fish. Bartram’s bass and Altamaha bass stand out not just in appearance, but in their DNA, revealed through detailed genetic analysis of hundreds of specimens. Scientists say this breakthrough helps Read more
Scientists discover tiny rocket engines inside malaria parasites
Malaria parasites contain tiny spinning crystals that have puzzled scientists for years. New research reveals they’re powered by a rocket-like reaction that breaks down hydrogen peroxide, releasing energy. This motion may help the parasite detoxify harmful chemicals and manage iron more efficiently. Read more
Scientists discover the protein that malaria parasites can’t live without
Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite’s unusual cell division process, ensuring its genetic materi Read more
