Scientists tackle long-standing questions about plutonium

June 5, 2006- 
LIVERMORE, Calif. — Scientists have gone a long way to solving a question about the nature of plutonium that has remained a mystery since the Manhattan Project. Plutonium behaves like no other element in nature. The bonding of its electrons causes its crystal structure to be uneven, similar to a mineral, and the nucleus is unstable, causing the metal to spontaneously decay over time and...

Study shows that genetic quality of sperm deteriorates as men age

June 5, 2006- 
New research indicates that the genetic quality of sperm worsens as men get older, increasing a man’s risk of being infertile, fathering unsuccessful pregnancies and passing along dwarfism and possibly other genetic diseases to his children. A study led by scientists at Lawrence Livermore National Laboratory (LLNL) and the University of California, Berkeley, found a steady increase in...

Nanotube membranes offer possibility of cheaper desalination

May 18, 2006- 
LIVERMORE, Calif. — A nanotube membrane on a silicon chip the size of a quarter may offer a cheaper way to remove salt from water. Researchers at Lawrence Livermore National Laboratory have created a membrane made of carbon nanotubes and silicon that may offer, among many possible applications, a less expensive desalination. The nanotubes, special molecules made of carbon atoms in a...

Researchers find metal gets stronger with three or more line dislocations

April 26, 2006- 
LIVERMORE, Calif. — Lawrence Livermore National Laboratory researchers have discovered that three is the magic number when it comes to strengthening metals. Since the Iron Age, metallurgists have known that metals such as steel become stronger and harder the more you hit (or beat) on them. But it wasn't always clear why this happened. Vasily Bulatov and colleagues at Lawrence Livermore...

April 25, 2006- 
WASHINGTON, D.C. — Today, the National Nuclear Security Administration (NNSA) announced the next phase of its academic computational science program that will focus on the goal of "predictive science." On May 16 and 17, NNSA's Office of Advanced Simulation and Computing (ASC) will present information on the Predictive Science Academic Alliance Program (PSAAP) to interested parties. They...

As numbers decline, more nuclear physicists are needed for homeland security and other work

April 22, 2006- 
LIVERMORE, Calif. — At a time when more nuclear physicists are needed to develop technologies for homeland security and to meet expected growth in the nuclear power industry, the nation’s universities are producing fewer of these researchers. That’s part of the message that Ed Hartouni, a physicist at Lawrence Livermore National Laboratory, presented today during a four-day national...
