  • Much more than a world first image of radioactive cesium atoms
    Thirteen years after the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (FDNPP), a breakthrough in analysis has permitted a world first: direct imaging of radioactive cesium (Cs) atoms in environmental samples.
  • The case for sharing carbon storage risk
    Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to susta...
  • New Nevada experiments will improve monitoring of nuclear explosions
    On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
  • Atomic nucleus excited with laser: a breakthrough after decades
    For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time ...
  • Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
    Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.
  • Major milestone reached for key weapons component
    Scientists have completed a crucial weapons component development milestone, prior to full rate production.
  • New beta-decay measurements in mirror nuclei pin down the weak nuclear force
    Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process of nuclear beta decay. The research found that the properties of the beta decays of lithium-8 and boron-8 are in perfect agreement with the predictions of the Standard Model.
  • Creating an island paradise in a fusion reactor
    In their ongoing quest to develop a range of methods for managing plasma so it can be used to generate electricity in a process known as fusion, researchers have shown how two old methods can be combined to provide greater flexibility.
  • With inspiration from 'Tetris,' researchers develop a better radiation detector
    A new detector system based on the game 'Tetris' could enable inexpensive, accurate radiation detectors for monitoring nuclear sites.
  • Researchers discover 'neutronic molecules'
    Researchers have discovered 'neutronic' molecules, in which neutrons can be made to cling to quantum dots, held just by the strong force. The finding may lead to new tools for probing material properties at the quantum level and exploring new kinds of quantum information processing devices.
  • Nuclear fusion, lithium and the tokamak: Adding just enough fuel to the fire
    Building upon recent findings showing the promise of coating the inner surface of the vessel containing a fusion plasma in liquid lithium, researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. The research includes observations, numerical simulations and analysis from their experiments i...
  • Plasma oscillations propel breakthroughs in fusion energy
    Researchers have discovered a new class of plasma oscillations -- the back-and-forth, wave-like movement of electrons and ions. The research paves the way for improved particle accelerators and commercial fusion energy.
  • AI for astrophysics: Algorithms help chart the origins of heavy elements
    The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time. Testing this theory and answering other astrophysical questions requires predictions for a vast range of masses of atomic nuclei....
  • Preventing magnet meltdowns before they can start
    High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches alto...
  • One way to improve a fusion reaction: Use weaknesses as strengths
    Scientists are embracing imperfection, using less-than-ideal magnetic fields to make the plasma more manageable.
