How Light-Harvesting Bacteria Toggle Off and On
Researchers clarified the atomic-level mechanism that enables bacteria to switch light harvesting off and on in response to potentially damaging overexposure to light. The results could have long-range implications for artificial photosynthesis and optogenetics—the use of light to selectively activate biological processes. Read more »
X-Ray Studies Key in Study Relating to Immune System-Signaling Protein
A grouping of amino acids—part of an important signaling protein, STING—plays an important role in activating the immune system. A study conducted through the Collaborative Crystallography program at the ALS confirmed how this part of the STING protein helps to bind a protein-modifying enzyme associated with autoimmune diseases and some cancers.

Shape transformation and self-alignment of Fe-based nanoparticles
Magnetic nanoparticles (MNPs) have widespread applications in biotechnology, materials science, engineering, and environmental studies. Thus, much attention has been paid to their controllable synthesis. Three new functions of iron-based nanoparticles are reported: shape transformation, oxidation prevention, and self-alignment.

A Frog Worth Kissing: Natural Defense Against Red Tide Toxin Found in Bullfrogs
Researchers have discovered how a protein produced by bullfrogs binds to and inhibits the action of saxitoxin, a deadly neurotoxin that causes paralytic shellfish poisoning. The findings could lead to the first-ever antidote for the compound, which blocks nerve signaling in animal muscles, causing death by asphyxiation when consumed in sufficient quantities. Read more »

June 2019 Message from the UEC
Fanny Rodolakis, the chair of the Users’ Executive Committee (UEC) for 2019, announces the Beamtime Buddies group on WhatsApp–a new communication tool for users at the ALS. Read more »
Catalyst Improves Cycling Life of Magnesium/Sulfur Batteries
Magnesium/sulfur batteries hold promise as a safer, energy-dense advancement, but previous iterations have suffered from extremely limited recharging capabilities. Studies at the ALS provided electrochemical insights into battery polarization and revealed how a titanium catalyst activates magnesium/sulfur compounds to improve battery performance. Read more »
Stephanie Gilbert Corder, Infrared Beamline Scientist
Stephanie Gilbert Corder is the newest beamline scientist at the ALS. Having been an ALS user in the past, she is eager to help others get reliable measurements to make the most of their beamtime. Read more »
Linking Structure to Behavior in Twisted Liquid Crystals
Researchers untangled connections between structure and behavior in a class of liquid crystals consisting of flexible, chain-like molecules that self-organize into twisting patterns. The study opens up new possibilities for designing novel liquid-crystal molecules that allow greater control of nanoscale behavior for technological applications. Read more »
