For the first time researchers demonstrate in an animal how heavy alcohol use leads to long-term behavioral issues by damaging brain circuits critical for decision-making.

Mosquitoes have been transmitting the West Nile virus to humans in the United States for over 25 years, but we still don’t know precisely how the virus cycles through these pests and the other animals they bite. A federally funded project aims to help pin down the process by using mathematical models to analyze how factors like temperature, light pollution, and bird and mosquito abundance affect West Nile virus transmission. The ultimate goal is to advise health departments of the best time of year to kill the bugs.
