The PROSPECT-I detector in operation at Oak Ridge National Laboratory’s High Flux Isotope Reactor. Designed to be as close to the reactor core as possible, this unique instrument performed precise antineutrino measurements in the challenging background environment found at that facility on the earth's surface.

In a new study published in Physical Review Letters, a team of researchers from U.S. universities and national laboratories has set stringent limits on the existence and mass of sterile neutrinos. 

Researchers at Penn State University and Lawrence Livermore National Laboratory are exploring "audible enclaves" — localized audio spots created through the nonlinear interaction of self-bending ultrasonic beams. The technique allows sound to be delivered to a precise location, circumventing physical barriers without the need for on-ear devices.

Researchers at Penn State University and LLNL unveil a novel technique that allows sound to be delivered to a precise location, circumventing physical barriers without the need for on-ear devices.

To-scale snapshots from molecular dynamics simulations illustrating hot-spot formation during pore collapse. The images show pores with diameters of 60, 100, 200 and 300 nanometers, illustrating that pores larger than 20 nanometers generate hot spots with scale-invariant (independent of size) temperature distributions.

Using LLNL’s Sierra supercomputer, a LLNL team has made significant progress in understanding how microscopic hot spots form in insensitive high explosives. 

High explosive LLM-105 before and after a laser-initiated burn inside a diamond anvil cell. Sample mass is ~ 1 microgram. The product is opaque at lower pressures and transparent at higher pressures (lower right panel). Note the increase and decrease in pressure, respectively.

LLNL researchers conducted laser ignition experiments in a diamond anvil cell and employed large scale quantum molecular dynamics simulations to investigate the products of deflagration at high pressures. 

General flowchart of the pipeline for building the Centrifuge reference database based on the BLAST nt database. The pipeline requires several weeks of processing on a high-performance computing server with high-memory-per-core ratio and a high-bandwidth, low-latency parallel filesystem.
