For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth had a much better chance of surviving treatment. (more…)

PNAS paper details mathematical model that sheds light on timing of key intracellular events

Phage therapy, which exploits the ability of certain viruses to infect and replicate within bacteria, shows promise for treating antibiotic-resistant bacterial infections. (more…)

ANN ARBOR — Can companies buying back their own stock time the market to get a better price? This was an unanswered question in corporate finance until now.

New research from University of Michigan finance professor Amy Dittmar indicates that some companies do time their repurchases to buy at a low price. It’s a way companies can make a shareholder-friendly move and a positive return on an investment. (more…)

UCLA life scientists present new insights on climate change and species interactions

UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.

“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.” (more…)

Research may help explain how human brain governs speech

As a bird sings, some neurons in its brain prepare to make the next sounds while others are synchronized with the current notes—a coordination of physical actions and brain activity that is needed to produce complex movements, new research at the University of Chicago shows.

In an article in the current issue of Nature, neuroscientist Daniel Margoliash and colleagues show, for the first time, how the brain is organized to govern skilled performance—a finding that may lead to new ways of understanding human speech production. (more…)
