ALS Director Announces Andreas Scholl as New Science Deputy

I am delighted to inform you that our search for a new science deputy has ended successfully with the appointment of ALS senior staff scientist Andreas Scholl. I look forward to working with him as we continue to manage this world-leading facility and get ready for ALS-U science. Read more »

Chiral Crystals Give Rise to Topological Conductors

Researchers have discovered materials whose chiral crystal structures produce chirality in their electronic behavior. These topological conductors retain their unique electronic properties regardless of defects and open new possibilities in materials research. Read more »

Electric Skyrmions Charge Ahead for Next-Generation Data Storage

Researchers have observed chirality for the first time in polar skyrmions in a material with reversible electrical properties. The combination of polar skyrmions and these electrical properties could one day lead to applications such as more powerful data storage devices that hold information even after a device has been powered off.

Salt in the Amazon Air Comes from Local Fungi

The abundant salt in the atmosphere above the Amazon basin has long been attributed to the Atlantic Ocean. But now, using the Advanced Light Source, scientists have found that much of it originates much more locally: fungal spores in the rainforest. Pinpointing the origin will improve climate models and understanding of rainforest ecosystems. Read more »

Meteorites Suggest Galvanic Origins for Martian Organic Carbon

Nanoscale analyses of Martian meteorites suggest that organic carbon on Mars may have been formed by electrochemical reactions between briny liquids and volcanic minerals, as might occur in a galvanic cell. The study has major implications for astrobiology and could also shed light on the reactions that led to life on the early Earth. Read more »
