Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

  1. Health & Medicine

    Simple test for cancer and heart disease

    Disease diagnosis often requires expensive equipment and tests to probe deep inside the body. But a new test relies on a fast, cheap and easy technique. And its answers appear on a strip of paper — just as they do on a pregnancy test.

  2. Brain

    Why boys face higher autism risk

    Boys develop autism at four times the rate seen in girls. Girls’ genes are better protected from the mutations linked to this brain disorder, data now suggest.

  3. Life

    Caught in the act

    Scientists observe some evolutionary speed demons as they adapt over the course of just a few years to new environmental conditions.

  4. Animals

    Churk: Not for Thanksgiving

    Here’s what happens when livestock breeders cross a chicken and a turkey

  5. Animals

    Glow kitties

    Cats light up when an experiment is successful.

  6. Health & Medicine

    New source for healthy fats

    Scientists found a way to produce fish oil without harming a single fish.

  7. Animals

    Awake at Night

    Mutant fruit flies can get by with less sleep than these insects normally need.

  8. Genetics

    A butterfly’s new green glow

    Scientists have tweaked a butterfly's genes to make its eyes glow green.

  9. Genetics

    A DNA Clue to Reading Troubles

    Scientists have identified a gene involved in a learning disorder called dyslexia.
