Greenland landscape history preserved under ice sheet

March 15, 2021- 
Greenland wasn’t always covered in ice. In fact, within the last 1.1 million years, Greenland had thriving vegetation and ecosystems. That is the conclusion of an international group of researchers, including a scientist from Lawrence Livermore National Laboratory (LLNL), that analyzed sediment at the base of the Camp Century ice core (1.4 kilometers deep) collected in 1966. The research...

Research identifies a pressure-induced increase in efficiency, phase transition of thermoelectric materials

March 10, 2021- 
Researchers have shown how applying pressure to a specific thermoelectric material, TiNiSn, increases its efficiency and leads to a structural phase transition. Thermoelectric materials are materials that can provide energy without the need for mechanical parts by converting heat energy into electrical energy. Thus, research aimed at these materials can identify new, more efficient materials...

Col. Joe Tringe, a group leader at Lawrence Livermore National Laboratory (LLNL) and an Air Force reservist, served as the final decision authority during the recent successful unarmed Minuteman III intercontinental ballistic missile launched from Vandenberg Air Force Base in California. See the video. As launch decision authority, Tringe worked closely with the mission director from the...

'Self-trained' deep learning to improve disease diagnosis

March 4, 2021- 
New work by computer scientists at Lawrence Livermore National Laboratory (LLNL) and IBM Research on deep learning models to accurately diagnose diseases from X-ray images with less labeled data won the Best Paper award for Computer-Aided Diagnosis at the SPIE Medical Imaging Conference on Feb. 19.

Goldstein receives the gold from DOE and NNSA

March 4, 2021- 
Outgoing director of Lawrence Livermore National Laboratory (LLNL) Bill Goldstein has received honors from the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) in recognition of his significant accomplishments as a scientist, leader in national security and director of LLNL. Goldstein retired March 1 after more than 36 years at LLNL and seven years as its...

Doubling creation of antimatter using same laser energy

March 3, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists have achieved a near 100 percent increase in the amount of antimatter created in the laboratory. Using targets with micro-structures on the laser interface, the team shot a high-intensity laser through them and saw a 100 percent increase in the amount of antimatter (also known as positrons). The research appears in Applied Physics...

Lab report outlines updates to state’s regulations for carbon capture, storage in effort to achieve neutrality

March 1, 2021- 
To reach economy-wide carbon neutrality by 2045 or earlier, California will likely have to capture, transport and geologically store tens of millions of tons per year of carbon dioxide (CO2) from large sources and from the atmosphere. California has an extensive regulatory framework that is rigorous, robust and will safeguard the environment, public health and safety during these...

Lab launches interdisciplinary Space Science Institute

Feb. 26, 2021- 
What are the next world-class, game-changing concepts and technologies that will address the most important questions in astrophysics or planetary science?

Study reveals cause of 3D asymmetry in ICF implosions

Feb. 25, 2021- 
Inertial confinement fusion (ICF) implosions require very high levels of symmetry in order to reach the high densities and temperatures required for fusion induced self-heating. Even percent-level deviations from perfect spherical symmetry can lead to significant distortions of the implosion and ultimately degrade fusion performance. To that end, researchers from Lawrence Livermore...
