Researchers around the country are adopting a technique developed in the Caltech lab of Nobel Laureate David Baltimore to try to guard against infection. The method, called VIP, was originally designed to trigger an immune response to HIV.
In a move that creates an academic division unlike any other among its peer institutions, Caltech has combined the disciplines of biology and biological engineering into a new Division of Biology and Biological Engineering.
The human body is full of tiny microorganisms, and the GI tract is home to the largest concentration and highest diversity of bacterial species. But how do these organisms persist and thrive in a system that is constantly in flux due to foods and fluids moving through it? A team led by Caltech biologist Sarkis Mazmanian believes it has found the answer, at least in one common group of bacteria: a set of genes that promotes stable microbial colonization of the gut.
Researchers have used a well-known, noninvasive technique to electrically stimulate a specific region deep inside the brain, causing volunteers to judge faces as more attractive than before their brains were stimulated.
