In a new study published in Nature Communications, a team of researchers led by Jay Keasling, CEO of the Department of Energy’s Joint BioEnergy Institute (JBEI), report that brewer’s yeast can be engineered to alter the flavor of beer. In this case, the scientists incorporated recombinant DNA derived from yeast, mint, and basil so the brewer’s yeast would biosynthesize aromatic monoterpene molecules that impart hoppy flavor. The benefits of this are two-fold: bioengineering can lead to flavor palette expansion while increasing the sustainability of the brewing process.
Beyond the WIMP: Unique Crystals Could Expand the Search for Dark Matter
A new particle detector design proposed by Berkeley Lab researchers, including Stephen Derenzo, Stephen Hanrahan, and Gregory Bizarri of theMolecular Biophysics and Integrated Bioimaging Division (MBIB) could greatly broaden the search for dark matter into an unexplored realm. Dark matter makes up 85 percent of the total mass of the universe, yet we don’t know its composition.
Doudna Featured on CBS ‘Sunday Morning’ Program
Reporter Mo Rocca explores “strokes of genius” in this episode. Among those he interviews is Jennifer Doudna, faculty scientist in the Molecular Biophysics and Integrated Bioimaging Division. The co-discoverer of the CRISPR gene-editing technology does not consider herself a genius, but rather thinks teams are more productive than individuals. Rocca also interviews internet pioneer Vint Cerf and musician Wynton Marsalis. Watch the episode.
JGI Develops a Reference Catalog for the Rumen Microbiome
Reported March 19, 2018, in Nature Biotechnology, an international team including JGI scientists presents one of the largest targeted cultivation and sequencing projects to date: a reference catalog of rumen microbial genomes and isolates cultivated and sequenced from the Hungate1000 collection. The catalog was produced through the coordinated efforts of rumen microbiology researchers worldwide. At the beginning of the project, there were only reference genomes for 14 bacteria and one methanogen. The Hungate catalog now contains a total of 501 genomes—410 newly generated from this study, plus an additional 91 already publicly available from other studies. Read the full story on the JGI website.
Marqusee Recipient of Protein Society Award
Susan Marqusee, faculty scientist in the Molecular Biophysics and Integrated Bioimaging Division, will receive the Dorothy Crowfoot Hodgkin Award, sponsored by Genentech, which is granted in recognition of exceptional contributions in protein science that profoundly influence our understanding of biology. Marqusee, a biophysical chemist whose work focuses on protein folding and dynamics, is one of the world’s top experimental scientists in the field of protein folding.
