Herpes virus infection drives HIV infection among non-injecting drug users in New York

Posted: 27 Jun 2014 01:37 PM PDT

HIV infection among non-injecting drug users doubled over the last two decades, a study has found. HIV and its transmission has long been associated with injecting drug use, where hypodermic syringes are used to administer illicit drugs. Now, a newly reported study shows that HIV infection among heterosexual non-injecting drug users (no hypodermic syringe is used; drugs are taken orally or nasally) in New York City has now surpassed HIV infection among persons who inject drugs.

'Bad' video game behavior increases players' moral sensitivity: May lead to pro-social behavior in real world

Posted: 27 Jun 2014 01:37 PM PDT

New evidence suggests heinous behavior played out in a virtual environment can lead to players' increased sensitivity toward the moral codes they violated. The current study found such guilt can lead players to be more sensitive to the moral issues they violated during game play. Other studies have established that in real life scenarios, guilt evoked by immoral behavior in the "real-world" elicits pro-social behaviors in most people.

Potential Alzheimer's drug prevents abnormal blood clots in brain

Posted: 27 Jun 2014 01:37 PM PDT

The brains of Alzheimer's mice treated with the compound RU-505 showed less inflammation and improved blood flow than those of untreated mice. The treated mice also performed better on memory tests, researchers report. For more than a decade, potential Alzheimer's drugs have targeted amyloid-², but, in clinical trials, they have either failed to slow the progression of the disease or caused serious side effects. However, by targeting the protein's ability to bind to a clotting agent in blood, the work in one lab offers a promising new strategy.

One shot, one chance: Can a soccer goalkeeper predict the kick strategy of a penalty taker?

Posted: 27 Jun 2014 06:44 AM PDT

Since 1978, 23 nations have had their fate determined by a penalty shootout in the FIFA World Cup. When the penalty taker walks up to the penalty spot, they have the dreams of a nation on their shoulders; they have one shot to score the goal while the goalkeeper has one chance to predict which direction the penalty taker is going to kick the ball. As the tension mounts, all pressure falls on the penalty taker to score the goal, however why do few expectations fall on the goalkeeper to save the goal? Much research has been conducted designed to help penalty takers score, however a new study has identified the characteristics of kick strategies used by penalty takers which may improve a goalkeeper's chance of making a save.

A group of researchers from the US has moved a step closer to preventing infections of the common hospital pathogen, Staphylococcus aureus, by revealing the mechanisms that allow the bacteria to rapidly clog up medical devices.

Small changes to US kidney allocation policy may help reduce geographic disparities in transplantation

Posted: 26 Jun 2014 02:27 PM PDT

Small changes to kidney allocation policies in the United States could help alleviate geographic disparities related to transplantation, according to a new study. The findings suggest that local changes may be more effective than the sweeping changes that are currently being proposed to address geographic disparities.

Risk factors for chronic kidney disease are present decades before diagnosis

Posted: 26 Jun 2014 02:27 PM PDT

Risk factors for chronic kidney disease (CKD) are present and identifiable 30 years before diagnosis, according to a new study. The findings suggest avenues for future research to determine whether certain early interventions can prevent future kidney disease.
