Tau-tally Microtubular!

Researchers at Lawrence Berkeley National Laboratory and UC Berkeley have combined cutting-edge cryo-electron microscopy (cryo-EM) with computational molecular modeling to produce a near atomic-resolution model of the interaction between microtubules – crucial components of eukaryotic cell ultrastructure – and microtubule-associated proteins called tau.

Profiling Extreme Beams: Scientists Devise New Diagnostic for Cutting-Edge and Next-Gen Particle Accelerators

The world’s cutting-edge particle accelerators are pushing the extremes in high-brightness beams and ultrashort pulses to explore matter in new ways. To optimize their performance – and to prepare for next-generation facilities that will push these extremes further – scientists have devised a new tool that can measure how bright these beams are, even for pulses that last only quadrillionths or even quintillionths of a second.

Early Career Spotlight: Zach Marshall Searches for Supersymmetry

Just five years after joining Berkeley Lab as a Physics Division fellow, Zach Marshall is co-leading an international team of researchers in search of supersymmetry — the theory that every known particle has a “superpartner” particle. Now with funding from an early career award announced last November, Marshall and his team are building a powerful super-scheduling platform that will help particle physicists process more data faster without investing in costly new computing infrastructure.
