    A research fellow at the University of Glasgow, Scotland, Daniel Streicker studies the ecology and evolution of emerging infectious diseases. Streicker’s research is aimed at detecting RABV variants and accurate identification of reservoir hosts. This is critical because some vampire bat species in the Amazon continue feeding on human blood in turn infecting their victims with rabies. Spread across four regions of Peru, Streicker has identified the individual and population level factors driving rabies virus transmission in 20 bat colonies. »

    A new study in Science showed that young fish have an overwhelming preference for water from healthy reefs. The researchers put water from healthy and degraded habitats into a flume that allowed fish to choose to swim in one stream of water or the other. The researchers tested the preferences of 20 fish each from 15 different species and found that regardless of species, family or trophic group, each of the 15 species showed up to an eight times greater preference for water from healthy areas. »

    About one in 68 children has been identified with autism spectrum disorder (ASD), according to recent CDC estimates—and the global prevalence of autism has increased 20- to 30-fold since the earliest epidemiologic studies of the late ‘60s and early ‘70s. Clearly, the number of individuals diagnosed with autism has gone up significantly, although the reasons aren’t entirely clear. Lawmakers on Capitol Hill recently were invited to hear about the latest science on autism diagnosis and treatment. The event was co-sponsored by AAAS and the DANA Foundation. »

    We need faster, easier and cheaper methods for identifying children with ASD, said Catherine Lord, a licensed clinical psychologist with specialties in diagnosis, social and communication development and intervention in ASD. Lord is renowned for her work in longitudinal studies of children with autism, as well as her role in developing the "gold standard" diagnostic tools (the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview – Revised (ADI-R)) used today. »

    While behavioral interventions are the standard treatment for autism, targeted drug treatment could someday reverse the effects of autism. Wayne State University researcher Diane Chugani is using pediatric PET imaging to study the effects of buspirone (an anxiety drug) on children with autism. »

    Renée and Barry Gordon are the parents of Alex, 22, a low-functioning autistic man. According to his mother, Alex can't do any of the daily tasks we often take for granted (he can't dress himself, or write his name with a pen or pencil, for example). "He has never spoken a word," said Renée Gordon. Alex does however, have some "savant-like" skills. He can read, and he can type and operate a computer and mobile device.

    Post-traumatic stress (PTS) or post-traumatic stress disorder (PTSD) can afflict individuals after a trauma or life-threatening event. It affects more than 5 million adults per year, according to the U.S. Dept. of Veteran Affairs, and is a particular concern for the military. AAAS and the DANA foundation co-sponsored an event in Washington, D.C., for lawmakers about how PTS/PTSD affects service members and veterans and how researchers are treating PTS through different styles of therapy. »
