  1. Physics

    Picture This: Christmas from space

    Satellite images show that cities brighten during holidays. Charting such changes can point to factors affecting energy use and contributing to global warming.

  2. Genetics

    Why animals often ‘stand in’ for people

    Rats, birds, fish — even flies and worms — can stand in for people in laboratory testing. This allows scientists to safely evaluate harmful chemicals as well as to identify and test potential new drugs. But such tests will never be a foolproof gauge of effects in people.

  3. Health & Medicine

    Can soft drinks speed aging?

    A new study suggests a reason why daily sugary-soda drinkers are more prone to disease: Guzzling these drinks shortens the protective caps on chromosomes. If the caps get too short, cells die.

  4. Health & Medicine

    Exercise builds brawn — and brains

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

  5. 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.

  6. 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.

  7. Microbes

    The war on superbugs

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

  8. 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.

  9. Microbes

    Superbugs: A silent health emergency

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

  10. 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.
