  1. Genetics

    Ancient DNA tests the notion that allergies are due to our dirtier past

    An analysis of ancient DNA and modern disease risk suggests some immune genes may reduce allergy risk rather than increase it.

  2. Health & Medicine

    Fluoride in U.S. drinking water does not reduce IQ, a new study finds

    Claims that fluoride in drinking water causes cognitive delays in kids are driving U.S. policy. A new study finds no evidence to back them.

  3. Animals

    To climb trees, cicadas look to the shadows

    Tree-climbing cicadas find their perches by looking for patches of darkness, a strategy known as skototaxis.

  4. Health & Medicine

    Digital heart twins can guide a lifesaving procedure

    Heart replicas helped doctors spot good targets for ablation in 10 patients. Months later, all of them are free of sustained faulty rhythms.

  5. Health & Medicine

    Smartwatch data can be used to assess early diabetes risk

    When combined with clinical markers, smartwatch data was able to help detect insulin resistance with nearly 90 percent accuracy.

  6. Genetics

    The Amazon molly — a sex-skipping fish — hacks evolution

    The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

  7. Genetics

    Wanderlust may be written in our DNA

    A new study suggests that inherited traits explain a small but measurable share of why some people relocate far from where they were born.

  8. Oceans

    Evolution didn’t wait long after the dinosaurs died

    New plankton arrived just a few millennia — maybe even decades — after the Chicxulub asteroid, forcing a rethink of evolution's catastrophe response speed.

  9. Health & Medicine

    A simple shift in schedule could make cancer immunotherapy work better

    A lung cancer trial bolsters a long-held idea that treatment timing matters, showing a simple shift could help immunotherapy work better and extend lives.

  10. Health & Medicine

    This baby sling turns sunlight into treatment for newborn jaundice

    A student created a low-cost baby carrier that filters sunlight to safely treat jaundice where electricity and equipment are scarce.

  11. Health & Medicine

    Color blindness hides a key warning sign of bladder cancer

    A large U.S. health records study suggests that difficulty seeing blood in urine may put color-blind patients at higher risk.

  12. Animals

    Lions have a second roar that no one noticed until now

    A machine learning analysis of wild lion audio reveals they have two roar types, not one. This insight might help detect where lions are declining.
