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 »
