All Stories by Meghan Rosen

  1. Animals

    RNA from mummified woolly mammoth is the oldest ever recovered

    Genetic details from the animal, named Yuka, give a snapshot into its last moments alive. The mammoth had been preserved in permafrost for 40,000 years.

  2. Chemistry

    Structures that work like Hermione’s magic handbag land a chemistry Nobel

    Richard Robson, Susumu Kitagawa and Omar Yaghi developed these metal-organic frameworks, which can trap pollutants, collect water from air and more.

  3. Health & Medicine

    Multiple-snake antivenom comes from blood of man bitten 202 times

    Tim Friede built immunity to snake venoms through bites and venom injections. His blood proteins now offer antivenom protection against 13 types of snakes.

  4. Tech

    This squirrel-like robot has some serious hops

    Salto the jumping robot has a claw-like gripper. Like a squirrel, it can adjust its movement to help it stay balanced to stick a landing on "branches."

  5. Health & Medicine

    Three U.S tick species may trigger a mysterious red-meat allergy

    This little-known allergy, known as alpha-gal syndrome, is potentially deadly. Here’s what we know about it — and how to avoid the tick bites that seem to cause it.

  6. Animals

    Dire wolves or not, these pups could help counter extinction

    Some question if these are just gene-tweaked gray wolves. Still, the tech behind the new "dire wolves" might help some living at-risk species avoid extinction.

  7. Artificial Intelligence

    AI-designed proteins target toxins in deadly snake venom

    The current way to produce antivenoms is outdated. In lab tests, AI-designed proteins could save mice from a lethal dose of snake toxin.

  8. Climate

    2024 set new record for hottest year, passing a dangerous heat threshold

    For the first year in recorded history, Earth’s average temperature topped 1.5 degrees Celsius above preindustrial levels.

  9. Chemistry

    Predicting and designing protein structures wins a 2024 Nobel Prize

    A biochemist and two computer scientists using AI shared the top award in chemistry.

  10. Humans

    Rain Bosworth studies how deaf kids experience the world

    This deaf experimental psychologist has found that babies are born ready to learn sign language, just like spoken language.

  11. Physics

    Forget moon walking, lunar visitors. Try horizontal running

    Researchers took over the Wall of Death, an amusement park attraction, to test out how astronauts might keep their strength up on the moon.

  12. Animals

    Cats play fetch — but only when they feel like it 

    Most cats that play fetch pick up the behavior on their own, a study finds. And those felines tend to dictate when fetching sessions begin and end.
