Lawrence Livermore researchers focus on fast flows in thermonuclear fusion

Sept. 24, 2021- 
Imagine having a balloon between both hands and trying to squeeze it with the same force on all sides so that it uniformly shrinks down. However, if you push on one side harder than the other the balloon won’t compress uniformly and will, in fact, move away from the hand that is pushing harder. The same thing happens when the drive pushing on an inertial confinement fusion (ICF) capsule...

Come on in, the water is superionic

Sept. 23, 2021- 
The interiors of Uranus and Neptune each contain about 50,000 times the amount of water in Earth’s oceans, and a form of water known as superionic water is believed to be stable at depths greater than approximately one-third of the radius of these ice giants. Superionic water is a phase of H2O where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline...

LLNL explores laser beam shaping to improve metal 3D printing

Sept. 22, 2021-

What if just one airborne particle was enough to infect you?

Sept. 16, 2021- 
For some diseases, exposure to just a single airborne particle containing virus, bacteria or fungi can be infectious. When this happens, understanding and predicting airborne disease spread can be a whole lot easier. That’s the result of a new study by a Lawrence Livermore National Laboratory (LLNL) scientist who developed a new theory of airborne infectious disease spread. This research...
