    Two drugs, one for cancer and one for arthritis, may be effective treatments for amyotrophic lateral sclerosis.

  2. Health & Medicine

    A spice takes on Alzheimer’s disease

    Curcumin, a spice used in yellow curry, may thwart Alzheimer's disease.

  3. Health & Medicine

    Antibiotic now tackles Parkinson’s

    A well-known antibiotic may slow the brain-cell death that causes Parkinson's disease.

  4. Health & Medicine

    New epilepsy drug is possible

    A drug mimicking a natural substance in the brain may offer a new therapy for epilepsy.

  5. Health & Medicine

    Thinking the way to stronger muscles

    Thinking about exercising a muscle can make it stronger.

  6. Physics

    Neutrino shortage may signal new force

    The dearth of neutrinos from a precision experiment casts some doubt on the prevailing model of particle physics and may indicate that a previously unrecognized extra force exists.

  7. Physics

    Shortest transistor makes its debut

    A novel type of single-molecule transistor built around a one-molecule-thick layer of organic molecules may eventually lead to faster, denser chips because the channel through which electrons flow is so short.

  8. Africanized bees rescue loner trees

    Africanized bees pollinate some of the big Brazilian forest trees now stranded in the middle of cleared land away from their native pollinators.

  9. Beer-flavoring compounds guide insects

    The class of compounds that give beer its bitterness does two more sober jobs in Hypericum flowers.

  10. Health & Medicine

    Low Radiation Hurts Bystander Cells

    New research confirms that alpha particles from decaying radon atoms can damage neighboring cells they don't directly hit and suggests a mechanism for this so-called bystander effect.

  11. Animals

    New lizard ties for ‘world’s smallest’

    A newly discovered lizard small enough to curl up on a dime ties for the title of the smallest of its kind in the world.

  12. Anthropology

    Human evolution put brakes on tooth growth

    A new analysis of fossil teeth indicates that the slower pace of dental development observed in people today dates back only about 100,000 years.

  13. Astronomy

    X-ray craft sees Venus in whole new light

    Astronomers have unveiled the first X-ray image of Venus.

  14. Animals

    Female ducks can double eggs by trickery

    Female goldeneye ducks can double their offspring by sneaking eggs into other females' nests before settling down to a nest of their own.

  15. Materials Science

    Synthetic molecules mimic bone growth

    Researchers have created molecules that assemble into a microscopic structure that mimics bone.

  16. Health & Medicine

    Delayed surgery aids spinal cord repair

    Postponing surgery to repair a severed spinal cord in rats improves the likelihood that the operation will counteract the injury.

  17. Health & Medicine

    Surprise! Fat proves a taste sensation

    The share of consumed fat that travels into a person's bloodstream depends on whether the person tasted fat to begin with.

  18. Tech

    Fly lends an ear to microphone design

    The unique way some flies localize sound has inspired engineers to design tiny directional microphones for hearing aids and surveillance devices.

  19. Math

    Knot Possible

    Knot theorists are getting closer to their goal of developing practical procedures for distinguishing knotted curves from unknotted ones.

  20. Tech

    Gadgets from the Quantum Spookhouse

    Despite much fanfare about proposed computers based on weird features of quantum mechanics, a whole array of other quantum technologies—navigation devices, chip-making equipment, atomic clocks and more—may also outshine their conventional cousins and be easier to implement than full-blown quantum computers.
