How sexual contacts with outsiders contribute to HIV infections within communities
While a number of strategies can prevent and control HIV transmission and spread, their effective use depends on understanding the sexual networks within and between communities. A paper published in this week's PLOS Medicine reports a detailed analysis with surprising results from the Rakai district in Uganda, one of the most studied areas of the HIV/AIDS epidemic in Africa.

What bat brains might tell us about human brains
Could a new finding in bats help unlock a mystery about the human brain? Likely so, say researchers at Georgetown University Medical Center who have shown that a small region within the amygdala, an almond-shaped structure in the brains of all mammals, is responsible for producing emotional calls and sounds. They say this discovery might be key to locating a similar center in human brains.

Yeast model reveals Alzheimer's drug candidate and its mechanism of action
Whitehead Institute scientists have used a yeast cell-based drug screen to identify a class of molecules that target the amyloid-β (Aβ) peptide involved in Alzheimer's disease (AD). This in vivo yeast model mimics the accumulation and cellular toxicity caused by Aβ in the neurons of AD patients. The work focuses on the drug, clioquinol, which removes copper from Aβ, thereby promoting Aβ's degradation and restoring endocytosis, a cellular protein-trafficking process disrupted in AD-affected neurons.

Motion-sensing cells in the eye let the brain 'know' about directional changes
In a detailed study of the neurons linking the eyes and brains of mice, biologists at UC San Diego discovered that the ability of our brains and those of other mammals to figure out and process in our brains directional movements is a result of the activation in the cortex of signals that originate from the direction-sensing cells in the retina of our eyes.

Muscle-controlling neurons know when they mess up, according to Penn research
Whether it is playing a piano sonata or acing a tennis serve, the brain needs to orchestrate precise, coordinated control over the body's many muscles. Moreover, there needs to be some kind of feedback from the senses should any of those movements go wrong. A team of researchers from the University of Pennsylvania and Princeton University has now begun to unravel the decades-spanning paradox concerning how this feedback system works.

CWRU wins $1.9 million grant to lead artificial platelet study
A research team led by Case Western Reserve University has received a $1.9 million National Institutes of Health grant to develop injectable artificial platelets that halt bleeding by sticking to bleeding sites and signaling natural platelets to home in on them. As they learn how the mechanisms work, they will investigate using artificial platelets to detect and treat thrombosis, metastasis and more.

Combination approach reduces spread of drug-related HIV
A computer model has created the most effective formula for reducing the spread of HIV among drug users in New York City over the next 25 years. The model recommends a combination of interventions, including increased HIV testing, improved access to substance abuse treatment, increased use of needle and syringe exchange programs, and broad implementation of antiretroviral treatment as prevention. The result would lower new infections by more than 60 percent by 2040.

Eliminating bacteria, changing lifestyle could lower risk in people genetically susceptible to colorectal cancer
Using a transgenic mouse model, Mount Sinai researchers found that the intestinal polyps depend on gut bacteria and that antibiotic treatment eradicated the bacteria and prevented polyp formation. They propose that bacteria in the gut cross into the intestine promoting inflammation and tumor growth.

Researchers at New York University and the University of Texas at Austin have discovered that carbohydrates serve as identifiers for cancer cells. Their findings show how these molecules may serve as signals for cancer and explain what's going on inside these cells, pointing to new ways in which sugars function as a looking glass into the workings of their underlying structures.

Big stride in understanding PP1, the ubiquitous enzyme
The enzyme PP1 has a key role in many of the body's healthy functions and diseases. It's so generally important that drug developers dare not target it. In a new study in the Proceedings of the National Academy of Sciences, Brown University scientists report a big leap in understanding how PP1 interacts with other proteins to behave specifically in distinct situations. That could lead to medicines that target it for precise benefits.

Experimental stroke drug also shows promise for people with Lou Gehrig's disease
Keck School of Medicine of University of Southern California neuroscientists have found that early muscle impairment related to Lou Gehrig's disease, also called amyotrophic lateral sclerosis, or ALS, in mice is proportional to the degree of damage to the blood-spinal cord barrier, which protects the central nervous system from toxins. Repairing damage to and restoring the blood-spinal cord barrier's integrity with an experimental neurovascular medicine being studied in human stroke patients appears to delay disease progression.

Binge drinking is harmful to older drinkers, may be hidden by weekly average
Studies examining the potential health benefits of moderate drinking generally focus on average levels of drinking rather than drinking patterns. A new study shows that, among older moderate drinkers, those who binge drink have a significantly greater mortality risk than regular moderate drinkers.

Hangovers do not seem to have much influence on the time to next drink
Many people believe that hangovers can either delay subsequent drinking due to pain and discomfort, or hasten drinking to relieve hangover symptoms. A new study investigates if a hangover that follows a drinking episode can influence the time to next drink. Results indicate that hangovers appear to have a very modest effect on subsequent drinking.

Blurred Lines? Sexual boundaries are not really all that blurred
Sexual aggression has become a common experience in bars. New findings show that approximately 90 percent of the incidents involve male initiators and female targets. The initiators' level of invasiveness was related to intoxication of the targets but not their own intoxication. This suggests that intoxicated women were being targeted, perhaps perceived as easier or more blameworthy.
