Scientists discovered a 75-million-year-old fossil in Mexico that reveals how tiny mammals outlasted the asteroid that killed the dinosaurs. The finding shows how being small and eating anything helped our ancient relatives survive Earth's deadliest day.
Scientists just found the world's oldest proof that our mammal ancestors laid eggs, tucked away in a South African fossil for 20 years. The discovery reveals how a pig-like creature survived Earth's worst mass extinction.
Scientists just confirmed that our mammal ancestors laid eggs, thanks to a rare fossil preserving a curled-up embryo from 250 million years ago. The discovery explains how one tough creature survived Earth's deadliest extinction event.
Researchers developed a breakthrough tracking method that identifies near-identical small mammal species by their footprints alone, achieving 96% accuracy. The non-invasive technology could transform how we monitor ecosystem health across the planet.
Scientists have discovered the first proof that our ancient mammal ancestors laid eggs, solving a mystery that's puzzled researchers for generations. The fossil also explains how these creatures survived Earth's deadliest mass extinction.
Scientists discovered a 252-million-year-old fossilized embryo in South Africa that proves our mammal ancestors laid eggs and reveals how they survived Earth's worst mass extinction. The find marks the first confirmed evidence of egg-laying in therapsids, the prehistoric creatures that gave rise to modern mammals.
Researchers discovered the first confirmed egg from a mammal ancestor, solving a 200-year mystery about how these ancient creatures reproduced. The fossil shows how one tough species survived Earth's worst extinction and paved the way for all mammals today.
A first-year college student on her very first fossil hunt in New Mexico discovered a mammal species unknown to science. The find proved that even well-studied sites can still reveal ancient secrets.
Texas researchers have discovered how to trigger limb regeneration in mammals by activating a dormant ability that's been hidden inside us all along. The breakthrough could transform how we heal from traumatic injuries.
Texas researchers have discovered mammals may not have lost the ability to regrow body parts after all. A two-step treatment successfully restored bone, joints, and tendons in animal studies by redirecting healing away from scar tissue.
Environmental groups just sued the federal government to finally enforce a 52-year-old law protecting whales and dolphins from deadly fishing gear worldwide. The move could save hundreds of thousands of marine mammals killed each year in fishing nets meant for seafood sold to Americans.
Scientists in South Africa discovered the oldest embryo fossil ever found, proving our mammal ancestors laid eggs 250 million years ago. The tiny creature inside reveals survival secrets from Earth's deadliest extinction event.
Scientists discovered the first confirmed egg from a mammal ancestor, solving a mystery about how tough little Lystrosaurus survived Earth's worst extinction event. The 250-million-year-old fossil shows these creatures laid large, soft-shelled eggs that helped their babies thrive in brutal conditions.
Scientists discovered a perfectly preserved mammal fossil the size of a fingernail in Mongolia's Gobi Desert, offering a rare glimpse into life 75 million years ago. The tiny skeleton survived alongside dinosaurs and could help explain how mammals adapted to extreme climate change.
Researchers discovered biological aging markers shared by humans, mice, rats, and monkeys, opening doors to treatments that could extend human lifespan. The team built a free online tool so scientists worldwide can test anti-aging therapies faster.
A tiny fox species dropped from 1,300 to just 100 animals in one year after a deadly virus hit their island home. Two decades of determined conservation work pulled them back from the brink in record time.
A fisherman's first yellowfin tuna turned into a viral lesson about nature's opportunistic side when a crafty sea lion nabbed the catch right off the boat. The video showcases the intelligent behavior scientists call "depredation," where marine mammals have learned to associate fishing boats with easy meals.
Researchers have digitally preserved the world's most endangered marine mammal using advanced scanning technology. The detailed 3D models of a rare vaquita skeleton are now freely available online to inspire conservation efforts.
Singapore's Resorts World Sentosa is stopping its wild dolphin sourcing and breeding program, marking a major shift in how the tourism industry treats marine mammals. Animal welfare advocates are calling it a positive step forward, though questions remain about the future of dolphins already in captivity.
Researchers finally solved a mystery millions of years in the making: why humans evolved to be awake during the day while most early mammals were nocturnal. The answer lies in tiny cellular switches that respond differently to daily temperature changes.
