Cellular Contamination Pathway for Plutonium, Other Elements, Identified

A team led by Rebecca Abergel working at the ALS reports a major advance in understanding the biological chemistry of radioactive metals, opening up new research into strategies for remedial action in the event of possible human exposure to nuclear contaminants. The results appear in the Proceedings of the National Academy of Sciences. More>

August 26 Talk on Reaching the Soft X-Ray Diffraction Limit

Improvements in brightness and coherent flux of more than two orders of magnitude over operational storage ring based light sources are possible using multi bend achromat lattice designs. These improvements can be implemented as upgrades, like the proposed ALS upgrade. This talk will introduce the general ideas behind the upgrades and describes some of the challenges. More>

New Mathematics Advances the Frontier of Macromolecular Imaging

A comprehensive understanding of complex nanostructures—like proteins and viruses—could lead to breakthroughs in some of the most challenging problems in biology and medicine. In a PNAS paper Berkeley Lab researchers have introduced new mathematical theory and an algorithm, which they call “Multi-tiered iterative phasing (M-TIP).”

Weyl Fermions Discovered With Help From Advanced Light Source

With help from ALS beamline 4.0.3, a research team led by Princeton University has discovered Weyl fermions, elusive massless particles that can behave as either matter or antimatter inside a crystal, which means it could provide a much more stable and efficient transporter of data than electrons.

Ancient Proteins Help Unravel a Modern Cancer Drug’s Mechanism

The cancer drug Gleevec is extremely specific, binding and inhibiting only the cancer-causing tyrosine protein kinase Blc-Abl, while not targeting homologous protein kinases found in normal, healthy cells. Researchers at the ALS have uncovered exactly why that is the case, pointing to novel methods of drug discovery. More>

Enhanced Microscopic Resolution for Improved Diagnostics

Simple, low-cost techniques developed by ALS affiliate Laura Waller are giving standard optical microscopes — and even smartphones — powerful new ways to see the minuscule. LED lights in a custom-built device boost resolution by making several microphotographs of a cell sample while changing only the angle of the lighting. More>

Investigating Buried Interfaces in Ferroelectric Materials

Researchers at Berkeley Lab and the Soleil Synchrotron in Paris have developed a new technique for investigating buried interfaces in ferroelectric materials. The new technique provides key information that should advance the exploitation of the unique properties of ferroelectric materials for encoding information. More>
