Alexander Varshavsky, Caltech's Howard and Gwen Laurie Smits Professor of Cell Biology, has been awarded the Otto Warburg Medal of the German Society for Biochemistry and Molecular Biology (GBM). The medal is considered to be the highest German award for biochemists and molecular biologists.
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.
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.
For their work in information and communication technologies, and biomedicine, Carver Mead, Moore Professor Emeritus of Engineering and Applied Science, and Alexander Varshavsky, Smits Professor of Cell Biology, have been honored by the BBVA Foundation as recipients of 2011 Frontiers of Knowledge awards.
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.
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).
