Most metals become brittle and crack in the cold, but new alloys from a team led by Berkeley Lab defy expectations: withstanding high heat and staying intact far below zero. In future, the materials could be used for extreme applications like jet engines and spacecraft. https://go.nature.com/4sBo1j3

Could a routine blood test reveal radiation exposure? Berkeley Lab scientists developed a machine learning tool that uses data from complete blood count (CBC) results, potentially offering an accessible way to screen workers at risk without the hurdles of existing methods.

A Simple Blood Test Could Reveal Hidden Radiation Exposure Using a routine blood draw, this machine learning model can detect radiation exposure to assess health risks.

Congratulations to Berkeley Lab’s Samuel Williams, one of this year’s recipients of the U.S. Department of Energy’s prestigious Ernest Orlando Lawrence Award! Williams created transformative performance modeling tools and algorithms that help supercomputers run more efficiently.

One of Williams’s most widely recognized achievements is the creation of the Roofline Performance Model, a visual framework that helps developers easily identify hardware bottlenecks and optimize their code.

“Sam’s development of the Roofline model has been absolutely transformative. Before Roofline, developers often struggled to understand exactly why their applications weren’t performing as they expected,” said Berkeley Lab Computing Sciences' Jonathan Carter. “By providing a clear, visual map of hardware bottlenecks, his work has demystified complex constraints and empowers researchers to push the boundaries of what our supercomputers can achieve.”

Congratulations to Berkeley Lab’s new Early Career Research Program (ECRP) awardees Asmit Bhowmick, Marcus Noack, Dan Wang, and Bingqing Cheng!

Established in 2010 to bolster the nation’s scientific workforce, the ECRP program supports exceptional researchers at the outset of their careers, when many scientists do their most formative work. Recipients use the funding to pursue projects that have the potential to solve scientific challenges and advance the country’s STEM capabilities.
