Observations confirm link between massive stars and weird supernovas

Observations confirm link between massive stars and weird supernovas May 21, 2014:

Nearly three decades ago, UC Berkeley astronomer Alex Filippenko observed a weird supernova that puzzled him and his colleagues. Some theorized that it was caused by the explosion of an aged but massive star called a Wolf-Rayet star. A supernova observed last year confirms this suspicion.

Polar bear genome gives new insight into adaptations to high-fat diet

Polar bear genome gives new insight into adaptations to high-fat diet May 8, 2014:

The polar bear diverged from the brown bear, or grizzly, as recently as several hundred thousand years ago, according to a genome comparison by UC Berkeley, Chinese and Danish researchers. They pinpointed genes involved in fat metabolism that could provide insights that will help humans deal with health problems caused by high-fat diets.

Research on the literal edge of 2D semiconductors

Research on the literal edge of 2D semiconductors May 1, 2014:

Researchers at Berkeley Lab and UC Berkeley have recorded the first observations of a strong nonlinear optical resonance along the edges of single layers of molybdenum disulfide. The existence of these edge states is key to the use of molybdenum disulfide in nanoelectronics, as well as a catalyst for the hydrogen evolution reaction in fuel cells, desulfurization and other chemical reactions.
