  1. Health & Medicine

    Bacteria Provide a Frontline Defense

    Bacteria genetically engineered to secrete microbe-killing compounds can fight disease in mice and rats.

  2. Some teens show signs of future depression

    Certain characteristics typify teens who suffer recurrences of depression as young adults, raising researchers' hopes for devising improved depression treatments.

  3. Tech

    Software enhances view of aircraft flaws

    New software can run an ultrasonic machine that will map corrosion beneath the surface of an airplane more quickly, safely, and effectively than can existing devices.

  4. Astronomy

    Cosmic afterglow steals the limelight

    Thanks to a chance cosmic alignment, researchers appear to have resolved the detailed structure of the afterglow of a gamma-ray burst—even though the parent burst erupted halfway across the universe.

  5. Animals

    Wasps drive frog eggs to (escape) hatch

    A tree frog's eggs can match their response to the degree of danger: all-out mass action for snakes but less activity for one wasp.

  6. Physics

    Solid-state insights yield physics Nobel

    The 2000 Nobel Prize in Physics went to three scientists and inventors whose work laid the foundation of modern information technology, particularly through their invention of rapid transistors, laser diodes, and integrated circuits.

  7. Pioneers of brain-cell signaling earn Nobel

    Three neuroscientists who delved into the ways brain cells receive and respond to signals from other cells won this year's Nobel Prize in Physiology or Medicine.

  8. Chemistry

    Nobel prize recognizes future for plastics

    The Nobel Prize in Chemistry went to three researchers for the discovery and development of plastics that conduct electricity.

  9. Intimate violence gets female twist

    An analysis of data on relationship violence in the general population finds that, excluding murder and sexual assaults, women prove slightly more likely than men to commit one or more aggressive acts against a partner—though men are more likely than women to inflict injuries that require medical help.

  10. Same interviewer, better memories

    Children may remember details of a witnessed crime more accurately if the same person conducts successive interviews with them.

  11. Health & Medicine

    HIV outwits immune system, again

    The AIDS virus uses immune system proteins to hitch rides on the antibody factories known as B cells, possibly helping it find potential host cells.

  12. Health & Medicine

    Aging protein saps muscle strength

    Proteins crucial for muscle strength begin to function poorly as rats get older.

  13. Physics

    Electron cloud mirrors fossil life-form

    Remarkable molecules whose electron clouds would resemble now-extinct marine creatures called trilobites could appear in experiments on ultracold atom clouds known as Bose-Einstein condensates, theorists predict.

  14. Physics

    Goo’s melting could keep battery cool

    Using the sometimes dangerous heat of lithium batteries to melt wax or similar materials may keep the potent cells cool enough for safe use in electric vehicles while also boosting the batteries' performance.

  15. What’s Worth Saving?

    A fracas over a biological term could have huge consequences for conservation.

  16. Animals

    Cetacean Seniors

    Whales that give new meaning to longevity.
