  1. Health & Medicine

    Climate change puts children’s health at risk now and in the future

    Heat waves, wildfires and other climate-related effects on the environment are particularly hard on children’s physical and mental health.

  2. Materials Science

    This ‘thermal cloak’ keeps spaces from getting either too hot or cold

    A new thermal fabric prototype could help keep cars, buildings and other spaces a comfortable temperature during heat waves while reducing CO₂ emissions.

  3. Planetary Science

    A rain of electrons causes Mercury’s X-ray auroras

    The first direct measurement of electrons raining down on Mercury suggests this particle precipitation causes most auroras in the solar system.

  4. Planetary Science

    NASA’s DART mission lofted a swarm of boulders into space

    Hubble telescope images of the asteroid Dimorphos reveal a halo of 37 dim, newfound objects — most likely boulders shaken loose from the surface.

  5. Health & Medicine

    Many sports supplements have no trace of their key ingredients

    A chemical analysis of 57 supplements found that 40 percent had undetectable amounts of key ingredients. Only 11 percent had accurate amounts.

  6. Climate

    Cow poop emits climate-warming methane. Adding red algae may help

    Adding a type of methane-inhibiting red algae directly to cow feces cut down methane emission from the poop by about 44 percent, researchers report.

  7. Math

    How geometry solves architectural problems for bees and wasps

    Adding five - and seven - sided cells in pairs during nest building helps the colonyfit together differently sized hexa gonal cells , a new study shows.

  8. Archaeology

    The oldest known horseback riding saddle was found in a grave in China

    The well-used saddle, dated to more than 2,400 years ago, displays skilled leather- and needlework. Its placement suggests its owner was on a final ride.

  9. Environment

    The most intense sunlight on Earth can be found in the Atacama Desert

    On the Chilean Altiplano plateau, every square meter of the ground receives, on average, more solar power than Mount Everest and occasionally almost as much as Venus.

  10. Animals

    The newfound Los Angeles thread millipede is ready for its close-up

    Found in Southern California, Illacme socal is the third of its genus found in North America, with the rest of its relatives scattered around the world.

  11. Chemistry

    How Benjamin Franklin fought money counterfeiters

    Researchers are confirming some of the techniques that Benjamin Franklin and his associates used to help early American paper currency succeed.
