Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported.

New research provides exciting insight into the molecular mechanisms associated with addiction and relapse. The study uncovers a crucial mechanism that facilitates motivation for alcohol after extended abstinence and opens new avenues for potential therapeutic intervention.

A group of computer scientists have found a way to tame multiprocessor computers, which behave in wildly unpredictable ways even as the systems become widespread in the industry.

High school and college students who understand the geological age of the Earth (4.5 billion years) are much more likely to understand and accept human evolution, according to a new study. A 2009 Gallup poll reported that 16 percent of biology teachers believe God created humans in their present form at some time during the last 10,000 years.

Scientists have gained new insight into why a relatively short-term hearing deprivation during childhood may lead to persistent hearing deficits, long after hearing is restored to normal. The research reveals that, much like the visual cortex, development of the auditory cortex is quite vulnerable if it does not receive appropriate stimulation at just the right time.

Obese patients with colon cancer are at greater risk for death or recurrent disease compared to those who are within a normal weight range, according to a new study.

Hip replacement patients with metal-on-metal implants (both the socket and hip ball are metal) pass metal ions to their infants during pregnancy, according to a new study.

People whose "bad" cholesterol and risk of future heart disease stay too high despite cholesterol-lowering statin therapy can safely lower it by adding a drug that mimics the action of thyroid hormone.

According to new findings, owning a video-game system may hamper academic development in some children. Boys who received a video-game system immediately had significantly lower reading and writing scores after four months than boys receiving a video-game system at the end of the experiment. Further analysis revealed that the time spent playing video games may link the relationship between owning a video-game system and reading and writing scores.

Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones. Called graphene, the material consists of a layer of graphite 50,000 times thinner than a human hair with unique electronic properties.

A 10-year effort by a scientist to develop transgenic rainbow trout with enhanced muscle growth has yielded fish with what have been described as six-pack abs and muscular shoulders that could provide a boost to the commercial aquaculture industry.

Some of our organs, such as the liver and the heart, are lateralized. As our bodies develop they mostly display bilateral symmetry across the vertebral column. A new molecular pathway, which plays a role in this symmetry in vertebrates, has recently been discovered.

Patients already taking warfarin who develop an acute stroke appear more likely to experience a brain hemorrhage following treatment with an intravenous clot-dissolving medication, even if their blood clotting function appears normal, according to a new study.

Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day. The research found that children with severe behavior disturbances had approximately double the risk of chronic widespread pain by the time they reached the age of 45 than children who did not have behavior problems.

Patients who undergo gastric bypass surgery experience changes in their urine composition that increase their risk of developing kidney stones, research suggests.

Researchers have sequenced for the first time the entire genome of a family, enabling them to accurately estimate the average rate at which parents pass genetic mutations to their offspring and also identify precise locations where parental chromosomes exchange information that creates new combinations of genetic traits in their children.

Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists created an atomic circuit that may help quantum computing become a reality.

Social insects -- ants in particular -- are usually thought of as selfless entities willing to sacrifice everything for their comrades. However, new research suggests that ant queens are also prepared to compromise the welfare of the entire colony in order to retain the throne.

Pharmaceutical companies could substantially reduce the expense of costly treatments for cancer and other diseases produced from mammalian or bacterial cells by growing these human therapeutic proteins in algae -- rapidly growing aquatic plant cells that have recently gained attention for their ability to produce biofuels.

A new assay allows scientists to discover whether ticks are carrying disease-causing bacteria and which animals provided their last blood meal. Assay results suggest three emerging diseases in the St. Louis area are carried by lone star ticks feeding on record-high populations of white tailed deer.
