Chemists at Caltech have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works.

Sarah Reisman, assistant professor of chemistry at Caltech, is one of 10 winners of 2013 Arthur C. Cope Scholar Award from the American Chemistry Society. Winning in the "early career scholar" category, Reisman will accept the award at the annual meeting of the American Chemistry Society in Indianapolis in September 2013.
According to the award citation, Reisman was recognized for her Caltech research group's original contributions to the understanding of complex molecule synthesis and reaction development.

Scientists and engineers around the world are working to find a way to power the planet using solar-powered fuel cells. Such green systems would split water during daylight hours, generating hydrogen that could be stored and used later to produce water and electricity. But robust catalysts are needed to drive the water-splitting reaction. Now Caltech chemists have determined the mechanism by which some highly effective cobalt catalysts work.

Caltech researchers have shown for the first time that a specific sugar, known as GlcNAc ("glick-nack"), plays a key role in helping cancer cells grow rapdily and survive under harsh conditions. The finding suggests new potential targets for therapeutic intervention.

Gregory C. Fu, a new faculty member and the Altair Professor of Chemistry at Caltech, uses his intuition and creativity to develop new chemical reactions that make chemical conversions more efficient—enabling organic chemists to convert reactants into their desired products in fewer steps or with higher yields than previously possible, for example. He talks about the creative aspects of organic chemistry, some of his current work, and making the move to Caltech.

Caltech chemists in the lab of Nobel laureate Bob Grubbs have developed a new class of catalysts that will increase the range of chemicals—from pharmaceuticals, insect pheromones, and perfume musks to advanced plastics—that can be synthesized using environmentally friendly methods.
