Programs succeed in reducing risky sex among HIV-positive minority men
Research has shown that HIV-positive African-American and Hispanic men who were sexually abused as children are particularly vulnerable to engaging in high-risk sex and experiencing depressive symptoms. Yet few HIV intervention programs exist to help them. Now, a new study finds that interventions that address the life experiences of these men can contribute significantly toward preventing high-risk behavior and reducing depression rates. This is largely due to the social support found within these programs.

Stillbirths, infant deaths lead to anxiety, guilt and stress among obstetricians
Nearly one in 10 obstetricians in a new study has considered giving up obstetric practice because of the emotional toll of stillbirths and infant deaths. Three-quarters of the 804 obstetricians who responded to a survey by researchers at the University of Michigan Health System reported that the experience took a large emotional toll on them personally.

Hox genes control the path of neurons responsible for development of the nervous system
In a new paper published this week in the open-access journal PLoS Biology, authors Filippo Rijli and colleagues demonstrate that pontine neuron migration in mice is controlled by specific Hox genes. They show that by knocking out the expression of the Hoxa2 gene the path of the neurons changes, causing them to end up in the wrong part of the brain.

Climate change hastens extinction in Madagascar's reptiles and amphibians
New research provides the first detailed study showing that global warming forces species to move up tropical mountains as their habitats shift upward. Herpetologist Christopher Raxworthy predicts that at least three species of amphibians and reptiles found in Madagascar's mountainous north could go extinct between 2050 and 2100 because of habitat loss associated with rising global temperatures. These species are moving upslope to compensate for habitat loss at lower and warmer altitudes.

A histone methyltransferase modulates antigenic variation in African trypanosomes
In this week's issue of PLoS Biology, George Cross and colleagues show that the chromatin modifying enzyme DOT1B helps to epigenetically regulate the number of VSGs each trypanosome parasite can have at a time and how fast each parasite can switch from one coat to another.

New MRI to debut in African nation of Malawi; will save lives, advance malaria research
Michigan State University physician Terrie Taylor studies cerebral malaria in Malawi where the vast majority of malaria patients are children. And, in order to get a closer look at the damage malaria does to a child, Taylor and colleagues study the child's brain, something that, up until now, could only be done in an autopsy. However, that will change this summer when a new magnetic resonance imaging unit -- the first MRI machine ever to come to Malawi -- will be put into operation.

Evolution of fruit size in tomato
In general, domesticated food plants have larger fruits, heads of grain, tubers, etc., because this is one of the characteristics that early hunter-gatherers chose when foraging for food. In addition to size, tomatoes have been bred for shape, texture, flavor, shelf-life and nutrient composition, but it has been difficult to study these traits in tomatoes because many of them are the result of many genes acting together.
