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.

Scientists have long seen evidence of social behavior among many species of animals. Right under our feet, it appears that roundworms are having their own little gatherings in the soil.

Eric Davidson, Caltech's Norman Chandler Professor of Cell Biology, has been awarded the 2011 International Prize for Biology by the Japan Society for the Promotion of Science. On November 28, Davidson received a medal at a ceremony in Tokyo and an imperial gift, a silver vase from Emperor Akihito. The award also includes ten million yen (more than $125,000 USD).

Over the past year, researchers at Caltech, and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the lab; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech led by Nobel Laureate David Baltimore have taken one step closer to that goal: they have developed a way to deliver these antibodies to mice and, in so doing, have effectively protected them from HIV infection.
