A deep dive into the interior of red dwarfs

Sept. 8, 2022- 
Red dwarfs are the most abundant stars in the Milky Way, making up 70% of all stars. But the physics of their interiors is not well understood. Heat is generated in the core and travels outward to the surface, but it is not clear whether that process occurs via radiation, convection or a combination of the two. The key factor determining whether red dwarfs are radiation- or convection...

Livermore researchers collect three awards among the top 100 industrial inventions

Sept. 7, 2022- 
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have garnered three awards among the top 100 industrial inventions worldwide.

Going big: Unlocking the study of some of the rarest and most toxic elements on Earth

Sept. 1, 2022- 
The synthesis and study of radioactive compounds are naturally difficult due to the extreme toxicity of the materials involved, but also because of the cost and scarcity of research isotopes. Now, Lawrence Livermore National Laboratory (LLNL) scientists and their collaborators at Oregon State University (OSU) have developed a new method to isolate and study in great detail some of the...

Asteroid sample lands on LLNL

Aug. 22, 2022- 
No need to worry, it is just a very small piece for scientific study. In December 2014, the Japanese Aerospace Exploration Agency launched the spacecraft Hayabusa2 to the asteroid 162173 Ryugu. In December 2020, when the sample-return capsule successfully landed safely back on Earth with pristine pieces of Ryugu that it had collected, Lawrence Livermore National Laboratory (LLNL)...
