Viruses have evolved a wide variety of ways to exploit parts of their host cells to avoid detection and to grow. Researchers at the Scripps Research Institute and the Berkeley Center for Structural Biology are learning more about how hepatitis C works to deceive its host cells.
Safely Studying Dangerous Infections Just Got A Lot Easier
A team of researchers led by NCXT Director Carolyn Larabell, in collaboration with scientists at Heidelberg University in Germany, used a technique called soft X-ray tomography (SXT) to quickly scan and analyze human lung cells infected with SARS-CoV-2. SXT not only significantly shortens the time frame, but provides more detail—increasing the chances of distinguishing subtle changes in the cell.
NIH Funds $40M Study to Compare Tau Tracers
The National Institutes of Health (NIH) recently awarded more than $40 million, distributed over five years, for a project that aims to compare two positron emission tomography (PET) imaging agents widely used to visualize misfolded tau protein—one of the hallmarks of Alzheimer disease (AD) and other dementias—in living brains. The effort will be led by co-principal investigators Suzanne Baker, a computational staff scientist in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division, and Tharick Pascoal, an assistant professor in the department of psychiatry at the University of Pittsburgh (Pitt).
Two from Biosciences Area Named AAAS Fellows
The American Association for the Advancement of Science (AAAS) has announced that 564 of its members—among them four scientists at Berkeley Lab—have been elected Fellows as part of the 2021 class. The two newly named Fellows from the Biosciences Area are: Eva Nogales, a senior faculty scientist in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division, and Scott Baker an affiliate with the Joint BioEnergy Institute (JBEI).
Crystallography for the Misfit Crystals
Nicholas Sauter, a computer senior scientist in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division, is co-leading a team working to provide a better way for scientists to study the structures of the many materials that don’t form tidy single crystals. Their new technique, called small-molecule serial femtosecond X-ray crystallography, or smSFX, supercharges traditional crystallography with the addition of custom-built image processing algorithms and an X-ray free electron laser (XFEL). In a paper published in Nature, the team demonstrated proof-of-principle for smSFX and reported the previously unknown structures of two metal-organic materials known as chacogenolates.
