Simulations capture life and death of a neutron

May 30, 2018 -  
Lawrence Livermore ( LLNL ) and Lawrence Berkeley national laboratory scientists, as well as scientists from UC Berkeley and other institutions, have simulated a "smidgen" of the universe to delve into determining the life and death of a neutron. Experiments that measure the lifetime of neutrons...

LLNL part of team studying protein filaments

May 25, 2018 -  
To learn more about diseases such as Alzheimer’s and Parkinson’s, scientists have zeroed in on invisibly small protein filaments that bunch up to form fibrous clusters called amyloids in the brain: How do these fibrils form and how do they lead to disease? Until now, the best tools for studying...

LLNL researchers use X-ray imaging experiments to probe metal 3D printing process

May 24, 2018 -  
Metal 3D printing undoubtedly has enormous potential to revolutionize manufacturing, but many industries have been slow to adopt the technology due to concerns over part quality and certification, which is essential to building confidence in the critical parts used in automotive and aerospace...

Ancient meteorite tells tales of Mars topography

May 23, 2018 -  
By looking at an ancient Martian meteorite that landed in the Sahara Desert, Lawrence Livermore National Laboratory ( LLNL ) scientists and collaborators have determined how and when the red planet’s crustal topographic and geophysical divide formed. Northwest Africa (NWA) 7034 is the oldest...

Researchers discover cause of radiation defects

June 1, 2018 -  
A team of scientists from Lawrence Livermore National Laboratory ( LLNL ) and Texas A&M University got a step closer to understanding radiation damage phenomena. They found that the density of collision cascades has a profound effect on defect interaction dynamics in silicon. The team...

LLNL-led team expands forensic method to identify people using proteins from bones

May 21, 2018 -  
When a team of researchers led by Lawrence Livermore National Laboratory (LLNL) developed a new biological identification method that exploits information encoded in proteins, they thought it could have multiple applications. Nearly two years later, they’ve turned out to be right. In September 2016...

PROSPECTing for antineutrinos

May 18, 2018 -  
The Precision Reactor Oscillation and Spectrum Experiment ( PROSPECT ) has completed installation of a novel antineutrino detector that will probe the possible existence of a new form of matter -- sterile neutrinos. PROSPECT, located at the High Flux Isotope Reactor ( HFIR ) at the Department of...

A warm look at water’s structure

May 14, 2018 -  
Boiling water traditionally involves adding energy to molecules by conduction, convection or thermal radiation. But Lawrence Livermore National Laboratory ( LLNL ) scientists and collaborators have figured out a way using an X-ray Free Electron Laser (XFEL) to heat water to temperatures above 100,...

Additive manufacturing advances K-9 training

April 26, 2018 -  
Additive manufacturing (AM) has gone to the dogs, thanks to Lawrence Livermore National Laboratory’s ( LLNL ’s) new approach to K-9 training materials. The process prints 3D objects that contain trace amounts of nonreactive explosives, resulting in several advantages for K-9s and their handlers...
