  1. Health & Medicine

    Don’t use dinner-table spoons for liquid medicines!

    Kids are safer when parents use precise tools to measure liquid medicines. Switching from teaspoons to metric tools could help, a new study finds.

  2. Health & Medicine

    To remember something new: Exercise!

    People who exercised strenuously for a half hour after learning something new cemented those memories. But the trick: Wait four hours before getting the heart pumping vigorously.

  3. Chemistry

    E-cigs create toxic vapors from harmless e-liquids

    New study finds a primary source of toxic vaping compounds. It’s the heat-driven breakdown of the liquids that hold nicotine and flavorings. And older, dirtier e-cigs make higher amounts of the toxic chemicals.

  4. Tech

    Moral dilemma could limit appeal of driverless cars

    Driverless cars will have to be programmed to decide who to save in emergencies — passengers or pedestrians. Many people aren’t yet sure they are ready to choose cars that make the most moral decision.

  5. Chemistry

    Gasp! At the movies, your breaths reveal your emotions

    Researchers took air samples as they screened movies. What people exhaled were linked to film scenes’ emotional tone, they found.

  6. Health & Medicine

    Zika vaccines look promising

    As a Zika epidemic surges through Brazil and northward, scientists are looking for drugs to keep more people from becoming infected. Several vaccines show promise in early tests — but none has yet been tried in people.

  7. Teen makes sure bacteria stay hands-off

    Germs are everywhere. One teen has designed a way to keep them from sticking to a surgeon’s gloves.

  8. Tech

    Clear, stretchy sensor could lead to wearable electronics

    Researchers have combined plastics and metal to make a transparent, stretchable sensor. It could soon find use in touchscreens, wearable electronics and more.

  9. Earth

    Earth’s tectonic plates won’t slide forever

    Earth’s surface morphs, owing to the movement of its tectonic plates. But those plates didn’t use to move so quickly. And in a few billion years they’ll grind to a halt, new research suggests.

  10. Climate

    Volcanic rocks can quickly turn pollution into stone

    A test program in Iceland injected carbon dioxide into lava rocks. More than 95 percent of the gas turned to stone within two years.

  11. Ink leads way to terminating termites

    Inspired by a classroom experiment, a teen has built a way to lure troublesome termites to their death — using the power of ink.

  12. Animals

    Catching ‘Dory’ fish can poison entire coral reef ecosystems

    More than half of saltwater-aquarium fish sold in the United States may have been caught in the wild using cyanide, new data show.
