Predatory bacteria bite their own

May 4, 2021- 
Predatory bacteria – bacteria that eat other bacteria – grow faster and consume more resources than non-predators in the same soil, according to a new study by Lawrence Livermore National Laboratory (LLNL) and Northern Arizona University. These active predators, which use wolf pack-like behavior, enzymes and cytoskeletal "fangs" to hunt and feed on other bacteria, wield important power in...

Direct drug delivery with carbon nanotube porins

May 3, 2021- 
Modern medicine relies on an extensive arsenal of drugs to combat deadly diseases such as pneumonia, tuberculosis, HIV-AIDS and malaria. Chemotherapy agents have prolonged lives for millions of cancer patients, and in some cases, cured the disease or turned it into a chronic condition. But getting those drugs into disease-ridden cells has remained a major challenge for modern pharmacology...

1D model helps clarify implosion performance at NIF

April 30, 2021- 
In inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF), a spherical shell of deuterium-tritium fuel is imploded in an attempt to reach the conditions needed for fusion, self-heating and eventual ignition. Since theory and simulations indicate that ignition efficacy in one-dimension (1D) improves with increasing imploded fuel convergence ratio, it is useful to...

Sterile neutrinos may be portal to the dark side

April 27, 2021- 
“Sterile neutrinos” are theoretically predicted new particles that offer an intriguing possibility in the quest for understanding the dark matter in our universe. Unlike the known “active” neutrinos in the Standard Model (SM) of particle physics, these sterile neutrinos do not interact with normal matter as they move through space, making them very difficult to detect. A team of...

Team improves polar direct drive fusion neutron sources for use in National Ignition Facility experiments

April 21, 2021- 
Scientists from Lawrence Livermore National Laboratory (LLNL) and the Laboratory for Laser Energetics (LLE) are working to improve polar direct drive (PDD) neutron sources on the National Ignition Facility (NIF), the world’s most energetic laser. PDD neutron sources are capsules filled with deuterium-tritium (DT) gas at ambient temperature and shot with robust laser pulses that do not...

Scientists reject restrictive heat flux models using directly driven gold spheres

April 15, 2021- 
A team of scientists have conducted an analysis of directly driven gold sphere experiments to test heat transport models used in inertial confinement fusion (ICF) and high energy density (HED) modeling. It was found that overly restricting the heat flux caused disagreement with measurement. However, simulations with a reduced nonlocal heat transport model quantitatively matched the...

Air Force reservists a vital part of Lab's workforce

April 14, 2021- 
On April 14, 1948, President Harry Truman established the United States Air Force Reserve, a force comprised of people who would stand ready to serve during wartime. Today the Reserve performs 20 percent of the work in the Air Force including specialized missions such as weather reconnaissance, firefighting and personnel rescue.
