After nine years in the Intellectual Property Office, Heidi Clark joined the ALS two months ago. Keep reading to find out what skills and secret talents she’s brought from previous jobs and just what “ham mode” means. Read more »
Genetic Blueprint for the Bioproduction of an Antidepressant Drug Candidate
A set of genes from a marine bacterium has been found to encode the biosynthesis of a promising antidepressant drug candidate. This work, which used the ALS to solve the structure of a key enzyme, could enable industrial-scale bioproduction of the drug in ways that are more efficient and sustainable than chemical synthesis.

Argon: Not So Noble in Earth’s Core
Researchers demonstrated the synthesis of a thermodynamically stable compound of argon and nickel at temperatures and pressures representative of the Earth’s core. The ability of argon, a noble gas, to react with other elements under these conditions may help solve outstanding geological questions, including the “missing argon paradox.” Read more »
Scientists Explore Egyptian Mummy Bones With X-Rays and Infrared Light to Gain New Insight on Ancient Life
Researchers from Cairo University worked with teams at the ALS to study soil and bone samples dating back 4,000 years. The experiments are casting a new light on Egyptian soil and ancient mummified bone samples that could provide a richer understanding of daily life and environmental conditions thousands of years ago.

Custom-Designed Models Reveal How Proteins Assemble on Minerals
Seashells, bone, and other hard tissues form through a little-understood process combining proteins and minerals. Researchers gained insight using a model system of proteins they designed and synthesized from scratch, characterizing how these building blocks assemble on mica. Read more »
Nobumichi Tamura Receives 2019 Klaus Halbach Award
Nobumichi Tamura received the 2019 Klaus Halbach Award in recognition for the software he developed to analyze microdiffraction data. The first version of the software was completed just before Christmas 1999 and has been a gift for many in the community ever since. Read more »
In Memoriam: Dave Humphries, Staff Engineer
We are saddened by the death of our friend and colleague, Dave Humphries. During his long tenure at Berkeley Lab and at the ALS in particular, Dave contributed in many outstanding ways to the success of the Laboratory and of our facility. Dave was at home with his family and passed away peacefully on September 13, 2019. Read more »
Multiple Levels of Chirality from Achiral Molecules
Liquid crystal samples were found to exhibit up to four levels of chirality, despite being made up of achiral molecules. The work sheds light on how molecular properties and competing interactions “propagate” order from the molecular level up to the microscale, leading to complexity similar to that found in biological materials.

X-Ray Experiments Contribute to Studies of a Drug Now Approved to Combat Tuberculosis
The U.S. Food and Drug Administration has approved a new antibiotic that, in combination with two existing antibiotics, can tackle one of the most formidable and deadly treatment-resistant forms of the bacterium that causes tuberculosis. Studies exploring the structure and function of the new drug benefited from x-ray experiments at the ALS. Read more »
Curtis Gomez, Electrical Safety Officer
Curtis Gomez recently became the ALS electrical safety officer. Besides looking out for hazards, his work in motor controls coordination draws from a TV and radio background—and working for a local band that made it big. Read more »
