| 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. |
| 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. |
| Some dogs and cats prone to sunburn: How to protect your animal from skin damage Posted: 27 Jun 2014 06:44 AM PDT Excessive sunbathing damages the skin. Humans are not the only ones who need to monitor their exposure to UV rays: animals are at risk too. Dogs and cats with white or thin coats are at particular risk, as are animals with very closely shorn fur or with certain pre-existing conditions. |
| 'Land grabbing' could help feed at least 300 million people Posted: 26 Jun 2014 06:33 PM PDT Crops grown on 'land-grabbed' areas in developing countries could have the potential to feed an extra 100 million people worldwide, a new study has shown. |
| Notorious pathogen forms slimy 'streamers' to clog up medical devices Posted: 26 Jun 2014 06:33 PM PDT 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. |
| 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. |
