Why do shrews lose brain size in winter but grow bigger noses? Scientists uncover a bizarre seasonal adaptation in tiny mammalsLong-clawed shrews exhibit unusual winter adaptations, shrinking their brains and skulls. However, their snouts grow noticeably larger duri...- Pangea Ultima: In 200 million years, Earth could have a new supercontinent, and its climate may be almost impossible for humans to surviveEarth's continents are moving, and a future supercontinent may form. Scientists model Pangea Ultima, a landmass forming in 200 million year...
- What did a Jurassic forest sound like? Scientists recreate 165-million-year-old insect calls and make a startling discovery with AI, lasers and fossil wingsScientists have reconstructed sounds of nine extinct Jurassic insects. Fossilized insect wings preserved sound-producing structures for ana...
- Why does the human brain take so long to develop? Scientists find a gene that may provide a clue about our extraordinary brainpower, cognitive abilitiesA human-specific gene influences brain immune cell development. These cells, called microglia, mature much slower than in mice. This extend...
- Science says crows remember faces of people who wronged them, here’s what their brains reveal about animal intelligenceWhen a crow responds to a specific person years after a significant encounter, its behavior suggests that the bird may have retained a memo...
- In 2017, USGS and MIT researchers dated a magma pulse to 251.9 million years ago. 9 years later, it links to Earth's worst extinctionEarth faced its worst extinction event around 252 million years ago. Volcanic activity in the Siberian Traps is the leading explanation for...
- 230 million years ago Dinosaurs first appeared on earth, but was there apex predator Jurassic like the size of a mouse ever existed? New research finds shocking detailsDinosaurs first appeared roughly 230 million years ago and eventually became the dominant land animals, holding that status until an astero...
- In Argentina, one fossil bone from a 236-million-year-old cynodont contained a rare clue about birth. Researchers found its newborn size resembled mammals, suggesting live birth evolved 95 million years earlier than thoughtNew fossil evidence challenges the long-held belief that ancient cynodonts laid eggs. A recent study found compelling proof that Chiniquodo...
- Originated 250 millions ago, Crocodiles and Birds closest living relatives yet one flies, apex predator can't, scientists have finally figured out whyReversion to a cold-blooded metabolism may have saved the crocodile lineage from extinction 66 million years ago when an asteroid ended the...
- Scientists rebuilt ancient primate brains from fossils and found a stunning clue to human evolution: The brain may have grown larger not simply to think more, but because our ancestors were processing an increasing amount of visual informationAncient primate brain evolution is now better understood. Researchers reconstructed fossil brain spaces using advanced imaging techniques. ...
- In 2016, scientists identified the globe skimmer as the world's longest-distance insect flyer. Years later, it reshaped our understanding of insect migrationResearchers from Rutgers University have uncovered genetic evidence demonstrating that dragonflies embark on remarkable long-distance migra...
- What was so special about Wrangel and St. Paul islands, where Woolly Mammoths survived until their extinction? Scientists revealed the answer two decades agoFor years, scientists believed the last woolly mammoths disappeared because inbreeding and genetic decline made survival impossible. A land...
- In the early 2000s, researchers found that holding their breath for days helps insects stay aliveMore than twenty years after those early studies attracted attention, scientists continue investigating how insects breathe, survive, and a...
- Nature's first cat! Every time your cat purrs, it echoes 30-million-year-old legacy that began with predator scientists call the world's first true catFirst Cat Proailurus: Long before modern cats evolved, an ancient feline called Proailurus roamed the forests of Europe and Asia around 30 ...
- Mountain lions left this suburb a century ago; one returned to Stanford's preserve in 2015, and woody plants grew 64-fold in just 11 yearsA Stanford study reveals that even a single visiting mountain lion can dramatically reshape ecosystems in small preserves. Researchers obse...
- Scientists found that childbirth can be harder than humans thought, as many primates have babies much bigger than birth canal; some species even dislocate pelvic bones to get through itA recent study challenges the long-held belief that humans uniquely face difficult childbirth. Researchers found that many primate species,...
- These 300-million-year-old baby fossils just turned a major evolution theory upside downAncient fossilized babies of crocodile-like predators are rewriting evolutionary history. Previously, scientists believed early land animal...
- How whales became biggest animals on Earth
- Our ancestors had powerful night-time visionNew York, April 21 (IANS) New genetic evidence confirms a long-held hypothesis that our earliest mammalian ancestors indeed had powerful ni...
- Jurassic period saw fastest mammal evolutionMammals were evolving up to ten times faster in the middle of the Jurassic than they were at the end of the period, coinciding with an expl...
