Only forty-five percent of baseball players were able to return to the game at the same or higher level after shoulder or elbow surgery. Researchers found that overall, only 20 of the 44 players returned to the same or higher level of professional baseball. For ballplayers at the major league, AAA, or AA level, the study found only 4 of 22 (18 percent) were able to return to the same or higher level.

Scientists have shown that microRNAs play an important role in stem cell differentiation. Understanding these key regulatory factors is critical for potential therapeutic use of stem cells.

The Nintendo Wii is a popular source of video game entertainment, but more recently, it has been adapted for a number of different uses. By integrating the Nintendo Wiimote with a laboratory computer, psychologists have extracted rich information about a person's reaching movements while they performed a learning task.

Good news for chips lovers everywhere -- new research in the journal Science of Food and Agriculture shows that pre-soaking potatoes in water before frying can reduce levels of acrylamide. Acrylamide is a naturally occurring chemical that occurs when starch rich foods are cooked at high temperatures, such as frying, baking, grilling or roasting.

A new study has uncovered a possible biological link between severe psychological stress and an increased risk of developing breast cancer. The study found that the stress hormone hydrocortisone may repress the activity of a tumour-suppressing gene known as BRCA1 that is related to breast cancer.

Scientists using a new drug screening method in Drosophila (fruit flies), have identified several drugs and small molecules that reverse the features of fragile X syndrome -- a frequent form of mental retardation and one of the leading known causes of autism. The discovery sets the stage for developing new treatments for fragile X syndrome.

Researchers at Johns Hopkins have discovered that two clinically different inherited syndromes are in fact variations of the same disorder. The scientists suggest that at least for this class of disorders, the total number and "strength" of genetic alterations an individual carries throughout the genome can generate a range of symptoms wide enough to appear like different conditions.

Scientists have identified the structure of a receptor in the brain implicated in conditions such as epilepsy and pre-menstrual tension. The same receptor has also been reported to be highly sensitive to alcohol.

Whether you are a habitual list maker, or you prefer to keep your tasks in your head, everyone pursues their goals in this ever changing, chaotic environment. We are often aware of our conscious decisions that bring us closer to reaching our goals, however to what extent can we count on our unconscious processes to pilot us toward our destined future?

Scientists have identified which variations of a specific gene determine a patient's initial response to treatment with the blood-thinning (anticoagulant) drug warfarin. Researchers found that the gene VKORC1 plays a major role in determining a patient's initial sensitivity to warfarin treatment -- when dosage amounts are most critical to prevent clotting problems in patients.
