New Georgia Tech research shows bacteria form distinct species and maintain cohesion through frequent DNA exchange via homologous recombination.

Hurricane storm surge flood waters can take a heavy toll on society. TACC supercomputer simulations are an important tool for U.S. state and federal agencies in protecting life and property.

There’s a downside to being a powerful alpha male -- at least if you’re a baboon. Studies show that despite their high rank, the No. 1 males in baboon society are also some of the most stressed out, as measured by their high levels of glucocorticoid hormones. But new research reveals it’s not the time they spend fighting with other males that raises their stress. Instead, it’s the effort they put into their mates.

AMHERST, Mass. — Researchers at the University of Massachusetts Amherst have quantified the impacts of a constellation of social factors on the spread of HIV. Their study, published in Health Care Management Science, found that a hypothetical 100% effective intervention addressing barriers to HIV treatment and care from depression, homelessness, individual and neighborhood poverty, education disparities, lack of insurance and unemployment could reduce the national HIV incidence by 29% over 10 years. The mathematical model, a novel integration of machine learning, probability theory and simulation, is positioned to be an important tool for decision-makers to optimize social programs and will have applications for other diseases.
