    Researchers Create the First Maps of Two Melatonin Receptors Essential for Sleep

    An international team of researchers used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to create the first detailed maps of two melatonin receptors that tell our bodies when to go to sleep or wake up and guide other biological processes. A better understanding of how they work could enable researchers to design better drugs to combat sleep disorders, cancer and Type 2 diabetes. Their findings were published in two papers today in Nature.

    Capturing the behavior of single-atom catalysts on the move

    Scientists are excited by the prospect of stripping catalysts down to single atoms. Attached by the millions to a supporting surface, they could offer the ultimate in speed and specificity. Now researchers have taken an important step toward understanding single-atom catalysts by deliberately tweaking how they're attached to the surfaces that support them - in this case the surfaces of nanoparticles.

    Watching Molecules Split in Real Time

    Watching Molecules Split in Real Time

    Using a new X-ray technique, a team of researchers was able to watch in real time as a molecule split apart into two new molecules. The method could be used to look at chemical reactions that other techniques can't catch, for instance in catalysis, photovoltaics, peptide and combustion research. The team, led by researchers from Brown University in collaboration with the Department of Energy's SLAC National Accelerator Laboratory, published their results in March in Angewandte Chemie.
