Supercomputer simulations of neutrons' inner turmoil and a new method that filters out "noise" yield the highest-ever precision calculation of nucleon axial coupling, a property crucial to predicting neutron lifetime.
UPTON, NY--If you want to understand how a material changes from one atomic-level configuration to another, it's not enough to capture snapshots of before-and-after structures. It'd be better to track details of the transition as it happens. Same goes for studying catalysts, materials that speed up chemical reactions by bringing key ingredients together; the crucial action is often triggered by subtle atomic-scale shifts at intermediate stages.
A team led by Berkeley Lab researchers has enlisted powerful supercomputers to calculate a quantity, known as the "nucleon axial coupling" or gA, that is central to our understanding of a neutron's lifetime.

Columbia investigators have made a major breakthrough in nanophotonics research, with their invention of a novel "home-built" cryogenic near-field optical microscope that has enabled them to directly image, for the first time, the propagation and dynamics of graphene plasmons at variable temperatures down to negative 250 degrees Celsius. If researchers can harness this nanolight, they will be able to improve sensing, subwavelength waveguiding, and optical transmission of signals.

The study, "Mutant Phenotypes for Thousands of Bacterial Genes of Unknown Function," has been published in the journal Nature and is by far the largest functional genomics study of bacteria ever published.
Inside every proton in every atom in the universe is a pressure cooker environment that surpasses the atom-crushing heart of a neutron star. That's according to the first measurement of a mechanical property of subatomic particles, the pressure distribution inside the proton, which was carried out by scientists at the Department of Energy's Thomas Jefferson National Accelerator Facility.
