While sequencing gut bacteria from people in Bangladesh, Berkeley Lab’s Jillian Banfield discovered phages, viruses that infect and reproduce inside bacteria, twice as big as any previously found in humans. She and her colleagues found the snippets of megaphage DNA in a CRISPR segment of one type of bacteria, Prevotella, that is uncommon in people eating a high-fat, low-fiber Westernized diet. Banfield and her team named the clade of megaphages “Lak phage” after the Laksam Upazila area of Bangladesh where they were found.

Researchers in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division have used a state-of-the-art cryo-transmission electron microscope to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy.

The Biosciences Area recently joined the California Air Resources Board, UC Berkeley, and UC’s Division of Agriculture and Natural Resources in co-hosting the California Bioresources Economy Summit, aimed at harnessing biotechnology to convert California waste streams from farms, forests, and landfills into valuable low-carbon fuels and products.

Associate Laboratory Director for Biosciences Mary Maxon keynoted the two-day conference as it kicked off January 29 at the David Brower Center in Berkeley. In her presentation, Maxon noted that expansion of the $370 billion per year U.S. bioeconomy could create more than 1 million jobs while reducing annual carbon emissions by up to 450 million tons.

Mutations in the proteins that regulate cellular processes such as growth, division, and death are often linked to cancer and other diseases. The proper function of one of these proteins, SHP2, depends on maintaining equilibrium in a structural tug-of-war between an open (active) and a closed (inactive) arrangement. A team of researchers from Brandeis University performed X-ray crystallography at Advanced Light Source (ALS) Beamlines 8.2.1 and 8.2.2—part of the Berkeley Center for Structural Biology—to elucidate the structures of healthy and mutated forms of SHP2 and the dynamic interchange between their open and closed conformations, as well as how SHP2 interacts with certain cancer drugs.

When researchers report developing a more efficient solar cell, or a technique that improves drug delivery, one of the inevitable follow-up questions they face is, “When will this be available to consumers?” In recent years, attempts to bridge the distance from lab bench to market have been promoted for researchers committed to seeing their work be applied to real world situations at universities, national laboratories and other institutions.

One such program is Fed Tech, launched in 2013 as part of the National Science Foundation’s Innovation Corps (I-Corps) program. Trent Northen and Peter Andeer, scientists in the Biosciences Area’s Environmental Genomics & Systems Biology (EGSB) Division at Lawrence Berkeley National Laboratory (Berkeley Lab), were part of the Fall 2018 cohort of Fed Tech Start-Up Studio, which culminated with a Pitch Day in late November. With entrepreneurs Rick Kjellberg and Jayan Rammohan, they were among 20 teams that participated in the eight-week program.
