Nuclear weapons: Predicting the unthinkable
If a nuclear weapon were detonated in a metropolitan area, how large would the affected area be? Where should first responders first go? According to physicist Fernando Grinstein, we have some initial understanding to address these questions, but fundamental issues remain unresolved. view more (2009-11-23)
Chromosomes dance and pair up on the nuclear membrane
Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. view more (2009-11-16)
Alberta's hidden valleys offer both resources and danger
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. University of Alberta researcher Doug Schmitt discovered a 300 metre deep, valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta. view more (2009-11-13)
SNM applauds House action to build medical isotopes reactor in the US
SNM applauds the U.S. House of Representatives for its passage of H.R. 3276-the American Medical Isotopes Production Act of 2009. view more (2009-11-09)
High-performance plasmas may make reliable, efficient fusion power a reality
In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. view more (2009-11-03)
Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB). view more (2009-10-29)
LANL Roadrunner models nonlinear physics of high-power lasers
For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers to high enough pressure and temperature to initiate fusion burn. view more (2009-10-29)
Endocrine Society calls for expanded scope and funding for stem cell research
Stem cell research holds great promise for the treatment of millions of Americans with debilitating and possibly fatal diseases. view more (2009-10-28)
Science at the Petascale: Roadrunner Results Unveiled
The world's fastest supercomputer, Roadrunner, at Los Alamos National Laboratory has completed its initial "shakedown" phase doing accelerated petascale computer modeling and simulations of a variety of unclassified, fundamental science projects. view more (2009-10-27)
Kraken becomes first academic machine to achieve petaflop
The National Institute for Computational Sciences' (NICS's) Cray XT5 supercomputer-Kraken-has been upgraded to become the first academic system to surpass a thousand trillion calculations a second, or one petaflop, a landmark achievement that will greatly accelerate science and place Kraken among the top five computers in the world. view more (2009-10-09)
MU Researchers Create Smaller and More Efficient Nuclear Battery
Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more... view more... (2009-10-08)
Loss of top predators causing surge in smaller predators, ecosystem collapse
The catastrophic decline around the world of "apex" predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller "mesopredators" that are causing major economic and ecological disruptions, a new study concludes. view more (2009-10-02)
Berkeley Lab Scientists' Computer Code Gives Astrophysicists First Full Simulation of Star's Final Hours
The precise conditions inside a white dwarf star in the hours leading up to its explosive end as a Type Ia supernova are one of the mysteries confronting astrophysicists studying these massive stellar explosions. view more (2009-09-23)
New beryllium reference material for occupational safety monitoring
Researchers at the National Institute of Standards and Technology (NIST), in collaboration with private industry and other government agencies, have produced a new reference material for beryllium. view more (2009-09-23)
Theoretical nuclear physics in China
In recent years several Large-Scale Scientific Facilities (LSSF) for nuclear, hadronic, and particle physics have been upgraded and constructed in China. view more (2009-09-17)
Genes may explain why children who live without dads have earlier sex
Previous research has found that children raised in homes without a biological father have sex earlier than children raised in traditional nuclear families. view more (2009-09-15)
Worldwide isotope shortage continues to pose significant challenges
SNM recently conducted a survey of nuclear pharmacies-pharmacies that supply the critical radioisotope Technetium-99m, which is used in more than 16 million nuclear medicine tests each year in the United States-to assess, anecdotally, the impact of the worldwide medical isotope shortage. view more (2009-09-09)
Using waste to recover waste uranium
Using bacteria and inositol phosphate, a chemical analogue of a cheap waste material from plants, researchers at Birmingham University have recovered uranium from the polluted waters from uranium mines. view more (2009-09-08)
Finding the ZIP-code for gene therapy: Scientists imitate viruses to deliver therapeutic genes
A research report featured on the cover of the September 2009 print issue of The FASEB Journal describes how Australian scientists developed a new gene therapy vector that uses the same machinery that viruses use to transport their cargo into our cells. view more (2009-08-31)
Scientists make first discovery using revolutionary long wavelength demonstrator array
Scientists from NRL's Space Science and Remote Sensing Divisions, in collaboration with researchers from the University of New Mexico (UNM) and the National Radio Astronomy Observatory (NRAO) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength Demonstrator Array (LWDA). view more (2009-08-19)
