Evaluate the evidence for the role of group behavior on individual and species' chances to survive and reproduce.

  1. Animals

    Industrious badger caught burying an entire cow

    Badgers are known to bury small animals. That allows them to save a meal for future dining. Now researchers have caught them caching something much bigger: young cows.

  2. Brain

    Among mice, scratching is catching — as in contagious

    Contagious itching spreads by sight, mouse-to-mouse. Scientists have now identified brain structures behind this phenomenon.

  3. Tech

    Cool Jobs: Doing real science in virtual worlds

    Virtual reality isn’t just for gamers. Scientists are using VR technology to tackle real-world problems.

  4. Life

    Cities drive animals and plants to evolve

    Biologists are finding that some species have used genetic changes to evolve — adapt — to the pollution and other stressors that they encounter in cities.

  5. Ecosystems

    America’s duck lands: These ‘potholes’ are under threat

    North America’s prairies are in trouble. Scientists race against the clock for clues about how to save the plants — and animals — that call it home.

  6. Microbes

    Will we know alien life when we see it?

    The hunt is on for extraterrestrials. But recognizing them may require some wiggle room in what we define as being alive.

  7. Animals

    Cool Jobs: Abuzz for bees

    These scientists are keeping bees healthy, making medicines for people from honey and constructing bee-inspired robots.

  8. Science & Society

    Shrimp on treadmills? Some science only sounds silly

    Research that may seem silly, at first glance, often has a rewarding aim. Here are some examples.

  9. Health & Medicine

    Violence spreads like a virus

    New research shows that the friends of violent teens are much more likely to become violent themselves.

  10. Genetics

    World’s tallest corn towers nearly 14 meters

    Short nights and a genetic tweak helped novel corn reach record heights.

  11. Environment

    Food-like smell on plastic may lure seabirds to eat it

    When plastic smells like supper, seabirds and other animals can be fooled into thinking it is food.

  12. Animals

    Animals can do ‘almost math’

    Humans aren’t the only animals with a number sense. Scientists are trying to figure out where and when it evolved.
