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)
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)
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)
Scientists use world's fastest supercomputer to model origins of the unseen universe
Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physics, Astrophysics and Cosmology group. 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)
Superheavy Element 114 Confirmed: A Stepping Stone to the Island of Stability
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have been able to confirm the production of the superheavy element 114, ten years after a group in Russia, at the Joint Institute for Nuclear Research in Dubna, first claimed to have made it. view more (2009-09-25)
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)
Public attitudes to new technology: Lessons for regulators
New technologies may change our lives for the better, but sometimes they have risks. Communicating those benefits and risks to the public, and developing regulations to deal with them, can be difficult - particularly if there's already public opposition to the technology. view more (2009-09-21)
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)
Hydrogen Storage Gets New Hope
A new method for "recycling" hydrogen-containing fuel materials could open the door to economically viable hydrogen-based vehicles. view more (2009-09-02)
PET/CT scans may help detect recurring prostate cancer earlier
A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed. view more (2009-09-02)
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)
