Scientists achieve higher precision weak force measurement between protons, neutrons

The n-helium-3 precision experiment, conducted at ORNL, measured the weak force between protons and neutrons by detecting the tiny electrical signal produced when a neutron and a helium-3 nucleus combine and then decay as they ....

Novel cell membrane model could be key to uncovering new protein properties

Researchers used neutron and x-ray scattering techniques at Oak Ridge and Brookhaven National Laboratories to characterize disc-shaped structures, known as bicelles, that mimic cell membranes. The rim of the disc comprises a detergent (purple), while ....
