  1. Unhealthy Change: Diversity in a bacterial colony can prolong infections

    Bacteria that live in biofilms can diversify into several different types, making infections harder to treat.

  2. Plants

    Give and Take: Plant parasites dole out genes while stealing nutrients

    New evidence suggests that parasitic plants can transfer their own genes into host plants.

  3. Health & Medicine

    High-fat diets slim down learning

    High-fat diets decrease the ability of male rats to learn and remember.

  4. Oxygen deficit linked to ADHD

    Sleep apnea may be a risk factor for attention-deficit hyperactivity disorder.

  5. Health & Medicine

    Drug abuse could be an occupational hazard

    Breathing minuscule amounts of painkillers administered to patients in surgery may increase an anesthesiologist's risk of abusing prescription drugs.

  6. Health & Medicine

    Acne drug affects brain function

    The antiacne drug Accutane may decrease activity in a part of the brain that regulates mood.

  7. Health & Medicine

    Prescription for Trouble: Antidepressants might rewire young brains

    Young mice exposed to a common type of antidepressant, known as a selective serotonin reuptake inhibitor (SSRI), showed symptoms of anxiety and depression in adulthood.

  8. Gene Doping

    Inserting genes for extra strength or speed could give athletes an unbeatable, and perhaps undetectable, advantage in competitive sports.

  9. Cavefish blinded by gene expression

    New evidence supports the theory that Mexican blind cavefish are sightless by evolutionary selection, not chance.

  10. Single gene turns flu deadly

    Variations in a single gene may have dramatically increased the virulence of 1918 Spanish flu.

  11. Trash to Treasure: Junk DNA influences eggs, early embryos

    A type of DNA once thought to be little more than genetic clutter may play a role in gene expression in mammalian eggs and newly formed embryos.

  12. Humans

    Nobel prizes: The sweet smell of success

    Nobel prizes in the sciences went to research on olfactory genes, subatomic particles, and the molecular kiss of death.
