Using his spare time at work and with the help of his Sandia National Laboratories colleagues, he designed a new cable connector that eliminates misalignments that could interfere with testing and potentially damage hardware.
People who experienced a disaster had a higher prevalence of problem alcohol use in the years after the disaster, and the rates of problem alcohol use increased over time. A study of nuclear power plant workers who experienced a disaster found that those who were exposed to life-threatening danger, discrimination, death of a colleague, or major property loss had an increased prevalence of problem alcohol use. However, for some, the increase in problem drinking did not occur until more than a year after the disaster. The study’s findings, recently published in Alcohol: Clinical and Experimental Research, point to the prolonged impacts on people who experience disaster and the importance of providing long-term monitoring and support beyond the immediate aftermath of the disaster.
Just as a medication bottle might be opened and the tamper seals carefully reattached by a bad guy, the International Atomic Energy Agency is concerned its devices could be bypassed and repaired or counterfeited. A possible solution? Engineers at Sandia National Laboratories have developed a groundbreaking prototype using “bruising” materials. Their innovation doesn’t just detect tampering; the new device boldly displays the evidence, like battle scars.
Fixed numbers of protons and neutrons can rearrange themselves within a nucleus. The gamma ray transitions from this reshuffling connect excited quantum energy levels, and the pattern in these connections provide a unique “fingerprint” for each isotope.
Neutrons, known for their ability to penetrate materials deeply, are key in nondestructive material analysis. Techniques like Neutron Resonance Analysis (NRA) and its variant, Neutron Resonance Transmission Analysis (NRTA), use these properties to identify elements and isotopes inside materials without damaging them.

With the rise in machine learning applications and artificial intelligence, it's no wonder that more and more scientists and researchers are turning to supercomputers. Supercomputers are commonly used for making predictions with advanced modeling and simulations. This can be applied to climate research, weather forecasting, genomic sequencing, space exploration, aviation engineering and more.
Colliding two heavy nuclei produces quark-gluon fireballs from which subatomic particles emerge. Fluctuations in the number of these particles from collision to collision carry important information about the QGP. Researchers used an approach called the maximum entropy principle to provide a crucial connection between experimental observations and the hydrodynamics of the QGP fireball.

Did you know that the oceans hold more uranium than can be found on land? Seawater could become another source of nuclear fuel, and researchers in ACS Central Science report a way to capture it effectively.
Nuclear science and technology (NST) impact our daily lives in a myriad of ways. From nuclear power to radiation cancer treatments and agriculture protection, NST is critical to improving the standard of living in countries with growing energy requirements.
As two neutron stars orbit one another, they release gravitational waves that sap energy from the orbit until the two stars eventually collide and merge.
The elements above iron on the periodic table are thought to be created in cataclysmic explosions like the merger of two neutron stars or in rare classes of supernovae. New research suggests fission may operate in the cosmos during the creation of the heavy elements. Combing through data on a variety of elements that reside in very old stars, researchers have found a potential signature of fission, indicating that nature is likely to produce superheavy nuclei beyond the heaviest elements on the periodic table.
Water is often the go-to resource for heat transfer, being used in large-scale cooling operations like data centers that power the internet and nuclear power plants that power cities. Discovering dynamic phenomena to make water-based heat transfer more energy and cost efficient is the ongoing work of Jonathan Boreyko, associate professor and John R.
