Another Milestone in Hybrid Artificial Photosynthesis

A team led by Peidong Yang, Michelle Chang and Chris Chang has combined semiconducting nanowires with select microbes to create an artificial photosynthesis system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.

New Mathematics Advances the Frontier of Macromolecular Imaging

A comprehensive understanding of complex nanostructures—like proteins and viruses—could lead to breakthroughs in some of the most challenging problems in biology and medicine. In a PNAS paper Berkeley Lab researchers have introduced new mathematical theory and an algorithm, which they call “Multi-tiered iterative phasing (M-TIP).”

Unlocking the Rice Immune System

Pam Ronald, a member of the Physical Sciences Division who directs JBEI’s Grass Genetics program, led a study that identified a bacterial signaling molecule that triggers an immunity response in rice plants, enabling the plants to resist a devastating blight disease. In addition to being a staple food, rice is the model for grass-type biofuels. More>

Protein Shifts More Than Just Color for Cyanobacterial Photoprotection

PBD’s Cheryl Kerfeld found that a photoprotective mechanism in cyanobacteria is triggered by an unprecedented, large-scale movement of the carotenoid pigment within the Orange Carotenoid Protein. This event could help scientists find new ways to protect artificial photosynthetic systems from overexposure to sunlight. More>
