Recent work at the ALS shows that the viruses infecting sulfur-oxidizing bacteria in the deep sea carry bacterial genes for the oxidation of elemental sulfur. Although the viruses themselves cannot use the sulfur, they likely supplement bacterial sulfur oxidation and then exploit the generated energy for viral replication. Read more »

Neurotransmitter receptor proteins are critical to learning and memory. Mutations are associated with neurological and neuropsychiatric conditions including Alzheimer’s, epilepsy, and autism. Structures of two such receptors, solved by x-ray crystallography, provide a blueprint for the development of therapeutics. Read more »
We are looking forward to an exciting and productive year at the ALS, with plans for new beamlines and capabilities coming online, and more users taking advantage of our technical and scientific expertise to produce a record number publications. At the ALS, we are encouraged by this year’s funding and are looking for new ways to focus on our core strengths while expanding partnerships to explore new opportunities. Read more »
A new measurement technique developed at the ALS is helping guide the semiconductor industry in next-generation nanopatterning techniques. NIST and IBM researchers collaborated on the technique, which allows scientists to evaluate the 3D buried features inside a film. The ALS is currently the only place in the world that has such capability.
Using soft x-ray ptychography, researchers at the ALS have demonstrated the highest-resolution x-ray microscopy ever achieved by imaging five-nanometer structures. The researchers used ptychographic imaging to map the chemical composition of lithium iron phosphate nanocrystals, yielding important new insights into a material of high interest for electrochemical energy storage.
