Telescope instrument is poised to begin its search for answers about dark energy

DOE/Lawrence Berkeley National Laboratory
Business Announcement

Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal approval milestone prior to startup.

DESI team prepares for telescope instrument's restart after unexpected shutdown

DOE/Lawrence Berkeley National Laboratory
Business Announcement

Despite a temporary shutdown of the Dark Energy Spectroscopic Instrument in Arizona - which was in its final stages of testing in preparation to begin mapping millions of galaxies in 3D when the pandemic struck - a variety of project tasks are still moving forward.

This COVID-19 detector has Berkeley Lab roots

DOE/Lawrence Berkeley National Laboratory

A technology spun from carbon nanotube sensors discovered 20 years ago by Lawrence Berkeley National Laboratory (Berkeley Lab) scientists could one day help healthcare providers test patients for COVID-19, the disease caused by the coronavirus SARS-CoV-2.

Capturing the coordinated dance between electrons and nuclei in a light-excited molecule

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Using SLAC's high-speed 'electron camera,' scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ultrafast electron diffraction, which scatters a powerful beam of electrons off materials to pick up tiny molecular motions.

Using machine learning to estimate COVID-19's seasonal cycle

DOE/Lawrence Berkeley National Laboratory
Business Announcement

One of the many unanswered scientific questions about COVID-19 is whether it is seasonal like the flu -- waning in warm summer months then resurging in the fall and winter. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) are launching a project to apply machine-learning methods to a plethora of health and environmental datasets, combined with high-resolution climate models and seasonal forecasts, to tease out the answer.

Untangling a key step in photosynthetic oxygen production

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Researchers zeroed in on a key step of photosynthetic oxygen production. What they learned brings them one step closer to obtaining a complete picture of this natural process, which could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.

X-ray experiments zero in on COVID-19 antibodies

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

An antibody derived from a SARS survivor in 2003 appears to effectively neutralize the coronavirus that causes COVID-19, opening the door for speedy development of a targeted treatment.

Probing materials at deep-Earth conditions to decipher Earth's evolutionary tale

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Scientists have developed a way to study liquid silicates at the extreme conditions found in the core-mantle boundary. This could lead to a better understanding of the Earth's early molten days, which could even extend to other rocky planets.

Scientists break the link between a quantum material's spin and orbital states

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Until now, electron spins and orbitals were thought to go hand in hand in a class of materials that's the cornerstone of modern information technology; you couldn't quickly change one without changing the other. But a study at the Department of Energy's SLAC National Accelerator Laboratory shows that a pulse of laser light can dramatically change the spin state of one important class of materials while leaving its orbital state intact.
