Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

  1. Genetics

    Explainer: How CRISPR works

    Scientists are using a tool called CRISPR to edit DNA in all types of cells.

  2. Animals

    Listening to fish love songs can predict their numbers

    Gulf corvinas croak for mates while in groups of millions. By listening to their undersea serenades, scientists may be able to estimate how many are out there.

  3. Animals

    Orangs nurse young for more than eight years!

    Orangutan moms and babies have been tricky to study in the wild, so researchers used dental tests to reveal a record setting nursing period.

  4. Animals

    Wild hamsters raised on corn eat their young alive

    European hamsters raised in the lab turn into crazy cannibals when fed a diet rich in corn, new data show. The problem may trace to a shortage of a key vitamin.

  5. Life

    How to make a ‘three-parent’ baby

    Scientists combined an egg, sperm and some donor DNA: The end result: what appears to be healthy babies.

  6. Oceans

    Creative ways to help coral reefs recover

    Coral reefs are under siege from threats ranging from climate change to explosives. But scientists are developing ways to rebuild reefs before they disappear.

  7. Agriculture

    Bananas under attack: Understanding their foes

    Fungal blights threaten the world’s most popular fruit. But genetic studies hint at new ways to combat some of these diseases.

  8. 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.

  9. Plants

    New species of terrifying tomato appears to bleed

    A new species of Australian bush tomato bleeds when injured and turns bony in old age.

  10. Animals

    Eating toxic algae makes plankton speedy swimmers

    After slurping up harmful algae, copepods swim fast and straight — making them easy prey for hungry predators.

  11. Animals

    Male peacocks twerk it to bring in the hens

    Scientists recorded peacocks with high-speed video cameras to learn the basic mechanics behind the shows they put on for peahens.

  12. Animals

    Spiders eat insects — and sometimes veggies

    Plant-eating spiders have been found on every continent except Antarctica, a new study notes.
