Solar Cells Get Boost with Integration of Water-Splitting Catalyst onto Semiconductor

Berkeley Lab scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell, and the result is a big boost to the stability and efficiency of artificial photosynthesis. The research comes out of the Joint Center for Artificial Photosynthesis (JCAP), established to develop a cost-effective method of turning sunlight, water, and carbon dioxide into fuel.

Gatekeeping Proteins to Aberrant RNA: You Shall Not Pass

Berkeley Lab researchers found that aberrant strands of genetic code have telltale signs that enable gateway proteins to recognize and block them from exiting the nucleus. Their findings shed light on a complex system of cell regulation that acts as a form of quality control for the transport of genetic information. A more complete picture of how genetic information gets expressed in cells is important in disease research.

New $10 Million Effort to Develop Advanced Water Splitting Materials

The Energy Department (DOE) recently announced $10 million, subject to appropriations, to support the launch of the HydroGEN Advanced Water Splitting Materials Consortium (HydroGEN). This consortium will utilize the expertise and capabilities of the national laboratories to accelerate the development of commercially viable pathways for hydrogen production from renewable energy sources. The new consortium is
