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.

Bacteria have evolved different systems for secreting proteins. A team of Caltech-led researchers proposes that one of those systems might work by shooting spring-loaded poison molecular daggers.

Researchers from Caltech now believe they have found a way to help the brain replace damaged myelin, a material that forms a protective cape around the axons of our nerve cells so that they can send signals quickly and efficiently.

Alexander Varshavsky, Caltech's Howard and Gwen Laurie Smits Professor of Cell Biology, has been awarded the 2012 King Faisal International Prize (KFIP) for Science. The winners of the prize, which also includes awards for medicine, Arabic language and literature, Islamic studies, and service to Islam, were announced in Riyadh, Saudi Arabia, on January 16.

A key feature of human and animal brains is that they are adaptive; they are able to change their structure and function based on input from the environment and on the potential associations, or consequences, of that input. To learn more about such neural adaptability, researchers at Caltech have explored the brains of insects and identified a mechanism by which the connections in their brain change to form new and specific memories of smells.
