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.

Study finds hazardous flame retardants in preschool, childcare settings

A new study led by UC Berkeley researchers finds that flame retardants are prevalent indoors in preschools and daycare centers, potentially exposing young children to chemicals known to be hazardous.

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.
