Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system’s asteroid belt for billions of years, share something else in common: the ingredients for life. They are the first meteorites found to contain both liquid water and a mix of complex organic compounds such as hydrocarbons and amino acids. ... Read more »

A polar mismatch between nonferromagnetic materials drives an electronic reconstruction in which interfacial ferromagnetism is induced. The emergence of such functionality at interfaces could enable new types of electronics for a range of applications, including logic, memory, sensing, and more.

If you add more lithium to the positive electrode of a lithium-ion battery, it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther between charges. But these lithium-rich cathodes quickly lose voltage, and years of research have not been able to pin down why—until now. ... Read more »
On December 6, the second in a series of online ALS user forums was held on the Advanced Light Source Upgrade (ALS-U) project. Presentations included an overview of the project and its current status, progress on designs for concept beamlines and optics, and ideas for the future of earth and environmental sciences research at the ALS. The next forum will be held Monday, January 22 at 10 a.m. PT. ... Read more »
Scientists have put the x-ray spotlight on composite materials in respirators used by the military, police, and first responders. The results provide reassuring news about the effectiveness of current filters and provide fundamental information that could lead to more advanced gas masks as well as protective gear for civilian applications. ...

Banda, ALS senior advisor and former ALS operations deputy, was presented the Berkeley Lab Citation at the 2017 Director’s Awards for Exceptional Achievement ceremony. The Citation recognizes extraordinary achievements in broad categories of science and operations, with special focus on service to the Lab and/or the DOE national lab complex. ... Read more »
The Proposal Study Panel (PSP) met on October 20 to oversee and finalize the scoring of General User Proposals for the 2018-1 January–July operating cycle and to make recommendations to the ALS Scientific Advisory Committee (SAC) on Approved Program applications. Beam time allocations for General User Proposals are completed, and users have been notified to view the results by logging in to ALSHub. Approved Program results will be announced shortly. ...

When I joined the Advanced Light Source 11 years ago, I came with limited understanding of ALS, but with great respect and admiration for both the facility and its staff from my time as a user. I wanted to learn and see how I could help, and it has been a wonderful experience. ... Read more »
Perpendicular magnetic anisotropy (PMA)—where magnetic moments in a thin film preferentially point out of the plane of the film—is an emergent phenomenon of both fundamental and technological interest. A combination of x-ray techniques demonstrate how to tune PMA in transition-metal oxide multilayers.
