Researchers identify how binge drinking may drive heart disease 
As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke, according to a study published today in the journal Atherosclerosis.

Space researchers developing tool to help disoriented pilots
Not knowing which way is up can have deadly consequences for pilots. This confusion of the senses, called spatial disorientation, is responsible for up to 10 percent of general aviation accidents in the United States, with 90 percent of these being fatal, according to the Federal Aviation Administration.

Odor ID not disguised by diet
Reporting in the October 31 issue of the online journal PLoS ONE, scientists from the Monell Center present behavioral and chemical findings to reveal that an individual's underlying odor signature remains detectable even in the face of major dietary changes.

Scientists invent device to control, measure chemicals in live tissue
Measuring an electrical current in an organism is pretty straightforward. All you need is an electrode. Measuring the flow of chemicals in cells or live tissue, however, is much more difficult because the molecules diffuse, mix with one another, and interact with their surroundings.

If your systolic stinks, 'rotten egg' gas may be why
Anyone with a nose knows the rotten-egg odor of hydrogen sulfide, a gas generated by bacteria living in the human colon. Now an international team of scientists has discovered that cells inside the blood vessels of mice — as well as in people, no doubt — naturally make the gassy stuff, and that it controls blood pressure.

High-altitude climbing causes subtle loss of brain cells and motor function

Smell is 'noisy' and 'in shades of grey'
University of Manchester scientists have overturned the 2,500-year-old theory that smell is detected by simple lock-and-key codes – using maggots with only one working olfactory sensory neuron (OSN), a nose with one nerve cell.

Small intestine can sense and react to bitter toxins in food
Toxins in food often have a bad, bitter taste that makes people want to spit them out. New UC Irvine research finds that bitterness also slows the digestive process, keeping bad food in the stomach longer and increasing the chances that it will be expelled.

Scientists discover why a mother's high-fat diet contributes to obesity in her children
New research suggests that pregnant women should think twice about high-fat foods. In a study from the University of Cincinnati and the Medical College of Georgia, scientists found that female mice fed high fat diets were more likely to have oversized offspring because fat causes the placenta to go into "overdrive" by providing too many nutrients to the fetus.

Cholesterol-lowering drugs and the effect on muscle repair and regeneration
Statins are powerful drugs that reduce "bad" cholesterol and thus cut the risk of a heart attack. While these medications offer tremendous benefits to millions, they can carry side effects for some. The most frequently reported consequence is fatigue, and about nine percent of patients report statin-related pain.

Lessons from the Iditarod
Since dogs became domesticated 15,000 years ago, they have worked with and lived next to humans, which some say may account for the special bond. Each of the 400 breeds and varieties are unique, but only one stands out as the ultra-athlete canine: the racing sled dogs.

Space: The not-so-final frontier
Of all environments, space must be the most hostile: It is freezing cold, close to absolute zero, there is a vacuum, so no oxygen, and the amount of lethal radiation from stars is very high. New research shows that some animals —the so-called tardigrades or 'water-bears'— are able to do away with space suits and can survive exposure to open-space vacuum, cold and radiation.

Children's refusal to swallow liquid medication — and their tendency to vomit it back up — is an important public health problem that means longer or more serious illness for thousands of kids each year.
