The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

Strain Turns Tin into a 3D Topological Dirac Semimetal

A small amount of compressive strain turns a nonmetallic form of tin into a topological Dirac semimetal—a kind of “supermetal” with very high electron mobility. With its rich topological phase diagram, the material shows promise for both novel physics and eventual device applications. ... Read more »

A Hollow Pyramid Unlocks Principles of Protein Architecture

Researchers have designed a hollow, pyramid-shaped protein with a controllable cavity size that could be useful in the capture and release of smaller compounds. The tools and techniques developed could be useful in analyzing and optimizing designed protein assemblies and understanding their behavior in solution. ... Read more »

Tribute to E.O. Lawrence Moves into ALS Lobby

There’s some new artwork gracing the ALS lobby—a stately portrait of Berkeley Lab founder Ernest Orlando Lawrence. The painting has a deep connection to the Lab, and so does the artist. He was a longtime Berkeley Lab employee and the father of Berkeley Lab Mechanical Technician Jim Dougherty, who frequently works on the undulators at the ALS. ... Read more »
