Astronomers have now solved a long-standing mystery of the Milky Way’s particle accelerators. They show that cosmic rays from our galaxy are very efficiently accelerated in the remnants of exploded stars.
Mice who inherit a particular chromosomal duplication from their fathers show many behaviors associated with human autism, researchers report. The duplicated chromosomal region in mice is the equivalent of human chromosome 15q11-13, the most frequent cytogenetic abnormality observed in autism, accounting for some five percent of all cases.
Just one drink can quickly go to your head. Researchers tested this well-known adage. Only six minutes after consuming an amount of alcohol equivalent to three glasses of beer or two glasses of wine, leading to a blood alcohol level of 0.05 to 0.06 percent, changes have already taken place in the brain cells, as [...]

Researchers have identified a protein that helps protect immature mouse sperm from oxidative stress. When male mice over one year old lacking this protein were mated with normal female mice, an increased incidence of miscarriages and fetal developmental defects were observed. These data have clinical relevance, as age-related DNA damage to human sperm is associated [...]

New research could offer a solution to one of the most annoying sounds on our roads — brake squeal. There are lots of mechanical myths about what causes a car’s brakes to produce that biting howl. The all too familiar piercing squeal is heard at road junctions and traffic lights the world over as drivers [...]

In primates including ourselves, the ability to register where others are looking is key in social circles. And, according to a new report, the way our brains process gaze-direction is much more sophisticated than a simple eyes-right vs. eyes-left.

Medical scientists are investigating how a species of fish from the Pacific Ocean could help provide answers to tackling chronic conditions such as hereditary high blood pressure and kidney disease. They are examining whether the Goby fish can help researchers locate genes linked to high blood pressure. This is because a protein called Urotensin II, [...]

A marker in the blood of both cats and humans that was identified in a recent study might signal both species’ susceptibility for a painful bladder disorder called interstitial cystitis, a condition that is often difficult to diagnose.

An enzyme known to play a key role in the development of emphysema serves as the first line of defense against bacterial infection of the lung, according to researchers. They also found that the antimicrobial activity comes from a small portion of the enzyme that is structurally and sequentially unique in nature.
