Here comes the sun: Tethered-balloon tests ensure safety of new solar-power technology

DOE/Sandia National Laboratories
Grant and Award Announcement

Researchers from Sandia National Laboratories recently used 22-foot-wide tethered balloons to collect samples of airborne dust particles to ensure the safety of an emerging solar-power technology. The study determined that the dust created by the new technology is far below hazardous levels, said Cliff Ho, the lead researcher on the project. Ho's team just received $25 million from the Department of Energy to build a pilot plant that will incorporate this technology.

Ultra-high-energy gamma rays originate from pulsar nebulae

DOE/Los Alamos National Laboratory

The discovery that the nebulae surrounding the most powerful pulsars are pumping out ultra-high-energy gamma rays could rewrite the book about the rays' galactic origins. Pulsars are rapidly rotating, highly magnetized collapsed stars surrounded by nebulae powered by winds generated inside the pulsars.

Cerreta named president of nation's professional society

DOE/Los Alamos National Laboratory

Ellen Cerreta, the Los Alamos National Laboratory's division leader for Materials Science and Technology, has been named president of The Minerals, Metals, & Materials Society (TMS), a professional society for scientists and engineers in those fields.

New pulsed magnet reveals a new state of matter in Kondo insulator

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A recent series of experiments at the National High Magnetic Field Laboratory (National MagLab) at Los Alamos National Laboratory leveraged some of the nation's highest-powered nondestructive magnets to reveal an exotic new phase of matter at high magnetic fields.

New AI tool tracks evolution of COVID-19 conspiracy theories on social media

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new machine-learning program accurately identifies COVID-19-related conspiracy theories on social media and models how they evolved over time--a tool that could someday help public health officials combat misinformation online.

Simulations reveal how dominant SARS-CoV-2 strain binds to host, succumbs to antibodies

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.

New method measures super-fast, free electron laser pulses

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

New research shows how to measure the super-short bursts of high-frequency light emitted from free electron lasers (FELs). By using the light-induced ionization itself to create a femtosecond optical shutter, the technique encodes the electric field of the FEL pulse in a visible light pulse so that it can be measured with a standard, slow, visible-light camera.

Los Alamos National Laboratory and NVIDIA announce next step in future-looking partnership

DOE/Los Alamos National Laboratory

Los Alamos National Laboratory today announced a major milestone resulting from its collaboration with NVIDIA to develop tailored High Performance Computing system architectures that will meet the Laboratory's diverse mission needs.

Moving toward a clean-energy future by advancing fuel cell technology

DOE/Los Alamos National Laboratory

The U.S. transportation industry is the nation's largest generator of greenhouse gases, accounting for nearly one-third of climate-warming emissions. To move towards a clean-energy future, developing zero-emissions technologies for heavy-duty vehicles is critical.

New research shows that Mars did not dry up all at once

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

While attention has been focused on the Perseverance rover that landed on Mars last month, its predecessor Curiosity continues to explore the base of Mount Sharp on the red planet and is still making discoveries.
