Michael Levi and David Schlegel, physicists at Berkeley Lab, discuss the future of the DESI project and how its forthcoming map will help scientists better understand dark energy.

Berkeley Researchers and Supercomputers to Help Create a Standard 3D Neuron Model

BigNeuron1

Before scientists can unlock the secrets of the human brain, they must fully understand neurons—the cells of our brain, spinal cord and overall nervous system. Thousands of detailed neuron images, from different organisms, currently sit in individual data collections across the globe, comprising several petabytes of data altogether. Despite this plethora of data, made possible

Bigger steps: Berkeley Lab researchers develop algorithm to make simulation of ultrafast processes possible

Berkeley Lab researchers carried out the first X-ray absorption spectroscopy study of a model electrolyte for lithium-ion batteries and may have found a pathway forward to improving LIBs for electric vehicles and large-scale electrical energy storage.

World Record for Compact Particle Accelerator

Using one of the most powerful lasers in the world, Berkeley Lab researchers have accelerated subatomic particles to the highest energies ever recorded. They used an emerging class of compact particle accelerator that physicists believe can shrink traditional, miles-long accelerators to machines that can fit on a table.

Latest Supercomputers Enable High-Resolution Climate Models, Truer Simulation of Extreme Weather

Wehner visualization

Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Berkeley Lab climate scientist Michael Wehner was able to complete a run in just three months. What he found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.
