Experiments validate the possibility of helium rain inside Jupiter and Saturn

May 26, 2021- 
Nearly 40 years ago, scientists first predicted the existence of helium rain inside planets composed primarily of hydrogen and helium, such as Jupiter and Saturn. However, achieving the experimental conditions necessary to validate this hypothesis hasn’t been possible — until now. In a paper published today by Nature, scientists reveal experimental evidence to support this long...

Laser-driven ion acceleration with deep learning

May 25, 2021-

Underneath it all: dishing the dirt on protists

May 18, 2021- 
Plants evolved in a world dominated by prokaryotic and eukaryotic microbes. Underneath the surface, plant roots interact with microbes in the soil, also called the rhizosphere microbiome. Although bacteria and fungi are well-studied in the rhizosphere (the layer closest to the roots), other components, including viruses and protists, are less well known. A protist is any eukaryotic...

Scientists identify key trends in high-energy-density mixing layers

May 17, 2021- 
Imagine a bottle of salad dressing containing oil and vinegar. The oil has a lower density than vinegar, so it floats on the vinegar. The oil will not stay trapped under the vinegar if the bottle is flipped upside down. It will bubble up through the vinegar until a stable state is restored. This simple physical process is known as RayleighTaylor instability, and it can be found in...

Observations show marine clouds amplify warming

May 13, 2021- 
A new analysis of satellite cloud observations finds that global warming causes low-level clouds over the oceans to decrease, leading to further warming. The work, led by researchers at Lawrence Livermore National Laboratory (LLNL), in collaboration with colleagues from Scripps Institution of Oceanography and the NASA Langley Research Center, appears online in Nature Climate Change. Th...

LLNL-developed thin-film electrodes reveal key insight into human brain activity
