Study Pinpoints Most Active Areas of Reactions on Nanoscale Particles

Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, researchers confirmed using a unique infrared probe at Berkeley Lab. The findings could help scientists customize the structural properties of catalysts to make them more effective in fostering chemical reactions. More>

New Model Shows Promise for Personalized, Precision Blood Transfusions

Amor Menezes and Adam Arkin of the Environmental Genomics & Systems Biology Division helped develop a simple, fast trauma coagulation model using control theory, published this week in Science Translational Medicine, which can personalize the treatment of severely injured patients with a bleeding disorder using only laboratory measurements that take a few minutes.

What’s the Best Electric Car for You? Take This App for a Test Drive

Maybe you think that you’ll be tethered to charging stations and unable to take long trips, or that the battery won’t last very long, or that you’ll need some special charger installed at home, or that, one way or another, an electric car simply won’t work for the way you live your life. The Lab’s Samveg Saxena is betting the phone in your pocket can change your mind. More>

More Detailed View of Vertical Cloud Structures Improve Climate Models

Using high-performance computers at NERSC, a team of researchers have improved a statistical representation of clouds in a climate model to capture clouds from all sides and in-between. They found that including the falling speed of these cloud components, along with the already-included dependency on the cloud’s turbulence strength, will improve the modelling of clouds. More>

HP Engineers Use ALS to Design Future Computer Memory

HP’s Suhas Kumar, while conducting experiments at the Advanced Light Source, has discovered a surprising new memristor operating mechanism, spatially uniform switching, that had not been directly demonstrated previously. He worked with the ALS’s David Vine and David Kilcoyne. More>

JBEI Develops New Tools for Engineering Saccharomyces cerevisiae

The yeast S. cerevisiae is an excellent organism for commercial-scale production of biological molecules, though its strain development remains painstakingly slow. Now, JBEI researchers have developed the largest, most comprehensive Cas9-based toolkit to quickly institute genetic changes in S. cerevisiae to optimize heterologous gene expression. More>

ALS Used to Study Mother-of-Pearl’s Connection to Ocean Temperature

Matthew Marcus, a scientist at the Advanced Light Source, assisted with PhotoElectron Emission spectroMicroscopy (PEEM) experiments in a study that found connections between ocean temperatures and the thickness of nacre, or mother-of-pearl, that coats pearls and some seashells. More>
