Manganese Reduction-Oxidation Drives Plant Debris Decomposition
ALS research has shown that manganese reduction-oxidation (redox) reactions are an important factor in controlling the rate of plant debris decomposition. Understanding the role of manganese will help build better models to predict how litter decomposition rates—and thus nutrient cycling and the ecosystem carbon balance—may behave in future climate scenarios.

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 »
