Cold Cases Heat Up To Identify Remains Through Lawrence Livermore Approach
2012-10-10 16:01:46

In an effort to identify the thousands of John/Jane Doe cold cases in the United States, a Lawrence Livermore National Laboratory researcher and a team of international collaborators have found a multidisciplinary approach to identifying the remains of missing persons. Using "bomb pulse" radiocarbon analysis developed at Lawrence Livermore, combined with recently developed anthropological analysis and forensic DNA techniques, the researchers were able to identify the remains of a missing...

Universal Order From Chaos
2012-10-05 13:03:23

[ Watch the Video: ESO Celebrates its 50th Anniversary ] Lee Rannals for redOrbit.com - Your Universe Online Researchers' discovery of self-organized electromagnetic fields in counter-streaming ionized gases is paving the way for scientists to have new ways to explore how order can emerge from chaos in the universe. "We've created a model for exploring how electromagnetic fields help organize ionized gas or plasma in astrophysical settings, such as in the plasma flows that emerge...

Sandia Nuclear Fusion Concept Undergoes Dry-Run Testing
2012-09-18 10:11:04

April Flowers for redOrbit.com - Your Universe Online Researchers at the Sandia National Laboratories have completed successful preliminary tests on magnetically imploded tubes called liners, which are intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years. The results of this research will be published in Physical Review Letters (PRL). Scientific break-even is one of the major performance measurements in fusion energy...

Laser Facility Makes Historic 500 Terawatt Shot
2012-07-18 06:06:44

Lee Rannals for redOrbit.com - Your Universe Online If all Marty McFly needed was 1.21 gigawatts to travel through time, then one feat accomplished at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) would provide him enough fuel to travel back to the future 413,223 times. The team made a historic record-breaking laser shot after 15 years of work on July 15, delivering over 500 terawatts, or 500 trillion watts, of power. The amount of power generated by...

Airborne Particulates Investigated
2012-06-27 13:37:38

For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace. The structure of micron-size particulate matter is important in a wide range of fields from toxicology to climate science (tobacco smoke and oil smoke particles are typically one micron in size). However, its properties are surprisingly difficult to measure in...

US Recaptures Reign As Having World's Fastest Supercomputer
2012-06-18 09:06:53

It has been more than two years since the US lost the number one spot on the TOP500 list of the world´s fastest supercomputers to China, which then lost that spot to Japan´s K Computer. Now, after IBM unveiled its Sequoia BlueGene/Q System which manages a sustained 16.32 petaflops, the title is returning to the US, dropping Japan to second. The computer, built for the National Nuclear Security Administration (NNSA) by IBM, outpaces Japan´s K Computer by more than 5 petaflops...

Precise Measurement Of Radiation Damage Identified
2012-06-06 06:55:26

Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material. "A full understanding of the early stages of the radiation damage process provides knowledge and tools to manipulate them to our advantage," said Alfredo Correa, a Lawrence Fellow from Lawrence Livermore National Laboratory in the Quantum Simulations Group. Nuclear radiation leads to highly energetic ions that can...

Simulations Show Nuclear Weapon Performance In Molecular Detail
2012-06-06 03:56:29

U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons. The simulations must be operated on supercomputers containing thousands of processors, but doing so has posed reliability and accuracy problems, said Saurabh Bagchi, an associate professor in Purdue University's School of Electrical and Computer...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
