    Exercise builds brawn — and brains

    One 20-minute session of leg exercises improved memory recall by about 10 percent.

  2. Tech

    Repelling germs with ‘sharkskin’

    A biotechnology company has found a way to repel superbugs without toxic chemicals. It mimics the texture of a shark’s skin.

  3. Tech

    Plants ‘listen’ for danger

    Scientists used lasers to show that plants can “hear” insect pests. Those leafy plants then mount a chemical attack in response to the bug’s chewing sounds — but not toward harmless noises such as a gentle breeze or a bug’s mating call.

  4. Microbes

    The war on superbugs

    Doctors and scientists are exploring ways to stem the growing global crisis of antibacterial resistance.

  5. Microbes

    Explainer: What you can do to fight antibiotic resistance

    Doctors and scientists are not the only people who can help preserve the effectiveness of life-saving antibiotics. Even patients have a role to play, as these tips show.

  6. Microbes

    Superbugs: A silent health emergency

    Have antibiotics become too popular? Overusing these medicines fuels resistant germs that pose a global health threat.

  7. Microbes

    Explainer: Where antibiotics came from

    A mold proved the source of the first known antibiotic: penicillin. But chemical dyes would lead to the first antibiotics used in treating people.

  8. Plants

    Wily bacteria create ‘zombie’ plants

    Scientists have discovered how some plant pathogens ensure their own survival by transforming flowering plants into strictly leaf-producing ones. These green ‘zombies’ attract insects that the parasites need to help them spread to other plants.

  9. Fossils

    Scary ‘chicken’ roamed Earth with T. rex

    Scientists have just pieced together evidence of a weird new dinosaur that sported sharp claws, feathers and a beak. And it just may have been one of the last dinos to roam Earth about 67 million years ago.

  10. Health & Medicine

    Some of chocolate’s health benefits may trace to ‘bugs’

    Dark chocolate offers people a number of health benefits. A new study finds that the breakdown of chocolate by microbes in the human gut be behind some benefits.
