New Hope for Retinitis Pigmentosa Patients
Using FTIR microspectroscopy at the NSLS in Brookhaven and at ALS Beamline 1.4.3, scientists got a first glimpse into the structural changes that result from point mutations in opsin, one of the causes of retinitis pigmentosa. Read more »
Luminescent MOFs for Mycotoxin Detection
Crystal diffractometry at ALS Beamline 11.3.1 helped scientists develop and understand a new, highly sensitive luminescent metal–organic framework for mycotoxin detection. Read more »
Conduction Along Magnetic Interfaces could Improve Memory Devices
Scientists have provided the first direct evidence of a controversial phenomenon: the boundaries between magnetic regions in an electrical insulator can become electrically conductive. This discovery can potentially lead to improvements in future memory storage devices. Read more »
Foreign DNA Capture during CRISPR–CAS Adaptive Immunity
Using macromolecular crystallography at Beamline 8.3.1 at the ALS, Berkeley researchers discovered how CRISPR/Cas captures foreign DNA for the bacterial immune system. Read more »
On the Road to ANG Vehicles with Increased Driving Ranges
An international team of researchers, using gas adsorption studies, in situ powder x-ray diffraction, and single-crystal x-ray diffraction, showed that there is a way to develop a new flexible metal–organic framework (MOF) material for enhanced natural gas storage on vehicles. Read more »
Discovery of Weyl Semimetals May Lead to Novel Future Spintronic Applications
A team of researchers using angle-resolved photoemission spectroscopy (ARPES) at ALS Beamline 10.0.1 found intriguing particles in a new phase of quantum matter: topological Weyl semimetals.
