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

  3. 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.

  4. 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.

  5. Physics

    Forget moon walking, lunar visitors. Try horizontal running

    This worm typically infects pythons. Though this is its first known infection in humans, other types of worms also can infect the human brain.

  9. Health & Medicine

    RNA work that led to COVID-19 vaccines wins 2023 Nobel in medicine

    Katalin Karikó and Drew Weissman overcame hurdles to using mRNA for medicine. This led to COVID vaccines — and maybe, one day, some for other infections.

  10. Fossils

    Ancient jellyfish? Upside down this one looks like something else

    A new look at an ancient sea animal called Essexella suggests it may have been a type of burrowing sea anemone, not a floating jelly.
