"Traditional research has studied autism as a genetic disorder and a disorder of the brain, but our work shows that gut bacteria may contribute to ASD-like symptoms in ways that were previously unappreciated," says Sarkis Mazmanian.
A group of researchers led by Caltech neuroscientist Ralph Adolphs has made the first recordings of the firings of single neurons in the brains of autistic individuals, and has found specific neurons in a region called the amygdala that show reduced processing of the eye region of faces.
Today Caltech announced the appointment of Thomas F. Rosenbaum as the Institute's ninth president. Dr. Rosenbaum is currently the John T. Wilson Distinguished Service Professor of Physics and provost at the University of Chicago.
New Caltech faculty member Lulu Qian performs research in the field of molecular programming to design synthetic molecular systems with neural-network-like behaviors and tiny robots from the programmed interactions of DNA molecules.
When you're a tiny mouse in the wild, spotting aerial predators—like hawks and owls—is essential to your survival. But once you see an owl, how is this visual cue processed into a behavior that helps you to avoid an attack? Using an experimental video technique, researchers at the California Institute of Technology (Caltech) have now developed a simple new stimulus with which they can spur the mouse's escape plans. This new stimulus allows the researchers to narrow down cell types in the retina that could aid in the detection of aerial predators.
Mitchell Guttman is a new assistant professor of biology on campus. He just arrived last month, having recently completed a fellowship at the Broad Institute of MIT and Harvard. Originally from Brooklyn, New York, Guttman received both his BS and MS degrees in 2006 from the University of Pennsylvania and completed his PhD at MIT in 2012. Since then, he has received an NIH Early Independence Award and was included on Forbes magazine's 30 Under 30: Science and Healthcare list.
