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...

MINOS experiment sheds light on how neutrinos change 'flavors'

March 30, 2006- 
LIVERMORE, Calif. — Scientists have successfully observed the transformation of neutrinos – a particle that is relatively massless, has no electric charge, yet is fundamental to the structure of the universe – from one type to another.The international team, including Livermore physicists Peter Barnes, Doug Wright and Ed Hartouni, working on the Main Injector Neutrino Oscillation Search...

Researchers measure high-pressure lattice dynamics of molybdenum

March 24, 2006- 
LIVERMORE, Calif. – For the first time, a group of Livermore researchers have been able to pin down the high-pressure lattice dynamics of the transition metal molybdenum by mapping its phonon energies under extremely high pressure.Measuring the phonon dispersion curves is key to understanding a range of properties such as sound velocities, elasticity and phase stability.Molybdenum, which in...

Changes in agricultural practices could help slow global warming

March 23, 2006- 
LIVERMORE, Calif. — Farmers who plant more crops, increase irrigation coverage and till the land less can have a profound effect on climate. Climate scientists from Lawrence Livermore National Laboratory found that models that included recent changes in agricultural practices, such as more irrigation, higher yielding crops, and less tillage, predicted lower temperatures than models that...

New research reveals oxygen's contributions to evolution

March 23, 2006- 
LIVERMORE, Calif. — It’s common knowledge that humans and other animals couldn’t survive without oxygen. But scientists are now learning a good deal more about the extent of our evolutionary debt to a substance that was once a deadly poison.New research at Lawrence Livermore National Laboratory (LLNL) and Boston University shows that many of the complex biochemical networks that humans and...
