Lyme Vaccine Proves Highly Effective
Two large studies find that a vaccine against Lyme disease vaccine can protect people against the tickborne disease, particularly after a booster shot is given.
Sizzling June fires up greenhouse debate
As extreme temperatures set records, the political fight over global warming continues.
Babies get a kick out of serial memories
Infants as young as 3 months old can learn and remember the order of mobiles viewed one after the other, a finding that contradicts previous studies on serially presented lists.
New spider: Unusual suspect steals web
A tiny, silver spider discovered in Taiwan eats pieces of other spiders' handiwork.
Hydrogen atoms chill to quantum sameness
After 20 years of trying, physicists have supercooled hydrogen into a Bose-Einstein condensate, in which all atoms are in the same quantum-mechanical state.
Muscle cells in damaged hearts may divide
A finding that human heart muscle cells can divide may help researchers discover how to regenerate tissue damaged by heart attacks.
Zapping curbs alien spinach
Irradiation appears to offer a way to keep water spinach, a black-market Asian delicacy, from taking root as a nuisance plant in U.S. waters.
Dust glow hints at wave of early star birth
New observations suggest that the bulk of the stars may have formed when the universe was just a few billion years old.
Possible Alzheimers gene stirs conflict
Researchers disagree on whether a specific gene on chromosome 12 influences a person's chance of getting Alzheimers disease late in life.
Memorys neural hit in schizophrenia
Brain images suggest that memory problems in schizophrenia stem from disturbances in areas that facilitate conscious recall and information retrieval.
Tracing the brains reading network
The reading order dyslexia may reflect an inability of a brain area known as the angular gyrus to work in concert with regions involved in speech comprehension.
View of HIV infection crystallizes
Atomic-scale pictures of an HIV protein reveal how the virus infects cells and eludes the immune system.

Asteroid may herald a new class
Astronomers have found a near-Earth asteroid that may never travel beyond the solar system.
Planets are candidates, not finds
Evidence of three planets orbiting nearby stars, described at a recent meeting, is highly preliminary, caution members of the team that presented the data.
Single-atom current heeds orbital count
Unlike bulk-metal conductors, single-atom electric contacts conduct electricity according to their individual chemical identities.
Foiling friction by jiggling a junction
Troublesome friction on the scale of microscopic machines nearly vanishes when lubricated surfaces are gently vibrated.
The Globe inside Our Planet
Earths inner core is turning out to be an alien world
Roughly the size of the moon, the inner core spins measurably faster than the rest of the planet and its hemispheres appear dissimilar.
The Overworked Heart
Research suggests molecular mechanisms for heart failure
Identifying proteins and enzymes implicated in heart damage may lead to ways of preventing or even reversing congestive heart disease.
