A study suggests that changes in an overactive immune system can contribute to autism-like behaviors in mice, and that in some cases, this activation can be related to what a developing fetus experiences in the womb.

Stephen L. Mayo, chair of the Division of Biology and Bren Professor of Biology and Chemistry at Caltech, has been named the William K. Bowes Jr. Foundation Division Chair. The William K. Bowes, Jr. Foundation, based in San Francisco, endowed the new division leadership chair with a $5 million gift, supplemented by an additional $2.5 million provided by the Gordon and Betty Moore Matching Program.

Caltech researchers have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs.

All animals seem to have ways of exchanging information—monkeys vocalize complex messages, ants create scent trails to food, and fireflies light up their bellies to attract mates. Yet, despite the fact that nematodes, or roundworms, are among the most abundant animals on the planet, little is known about the way they network. Now, research led by California Institute of Technology (Caltech) biologists has shown that a wide range of nematodes communicate using a recently discovered class of chemical cues.

In studies that mark a major step forward in our understanding of stem cells' fates, a team of Caltech researchers has traced the stepwise developmental process that ensures certain stem cells will become T cells—cells of the immune system that help destroy invading pathogens.

Nearly all motile bacteria can sense and respond to their surroundings through a process called chemotaxis, which begins with proteins known as chemoreceptors. Now researchers at Caltech have built the first model that depicts precisely how chemoreceptors and the proteins around them are structured at the sensing tip of bacteria. Because chemotaxis plays a critical role in the first steps of bacterial infection, a better understanding of the process could pave the way for the development of new, more effective antibiotics.
