Proteins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult. Now, a team of chemists and neurobiologists led by Timothy Dore at the University of Georgia and Erin M. Schuman at the California Institute of Technology has found a way to use light to regulate protein synthesis in specific locations.
The new method, which uses so-called "caged compounds" that can be turned on with light, could lead to more intricate studies of such important but poorly understood processes, such as protein synthesis in nerve synapses.
The research was published today in the journal Chemistry & Biology. Coauthors on the paper are Schuman, Michael Goard, Girish Aakalu, Carlo Quinonez and Jamii St. Julien, all of the Howard Hughes Medical Institute and Division of Biology at the California Institute of Technology. Lesya Fedoryak from Dores lab is also an author of the paper, as is Stephen Poteet, now a medical student at the University of Alabama, Birmingham, who participated in UGAs Chemistry Summer Undergraduate Research Program in 2001.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
