Berkeley Lab
The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

The CRISPR Target-Recognition Mechanism

CRISPR-associated (Cas) proteins have revolutionized gene editing by vastly simplifying the insertion of short snippets of new (“donor”) DNA into very specific locations of target DNA. Now, researchers have discovered how the Cas proteins are able to recognize the target locations with such great specificity. ... Read more »

PepsiCo Explores Future Food Products at the ALS

Global food and beverage giant PepsiCo has been using ALS tomography beamline 8.3.2 to understand more about the chemical structure and behavior of their starch-based snack foods, with the goal of creating a whole new category of snacks that consumers cook at home in their own microwaves.

CO Adsorption on Pd(100) Studied by Multimodal Ambient Pressure X-Ray Photoelectron and Infrared Reflection Absorption Spectroscopies

The first combined infrared spectroscopy and ambient-pressure XPS study was demonstrated at Beamline 11.0.2. The in situ vibrational and core-level spectroscopies in the Torr pressure range offer complementary information on the properties of surfaces and adsorbates while closing the pressure gap between laboratory measurements and applications.  The multimodal spectroscopy also allowed the identification of the C 1s binding energy and quantification of an uncommon atop CO species on a Pd(100) surface. ...

Microbes Linked to Drier Human Skin

Genetic analyses and infrared studies have found that archaea, a type of microbe commonly found in extreme environments, are also found on human skin. The results suggest that an increase in archaea is linked to reduced skin moisture and that they are most abundant in subjects younger than 12 and older than 60. ... Read more »
