  • Plasma heating efficiency in fusion devices boosted by metal screens
    Scientists have performed computer simulations confirming a technique that prevents the production of unhelpful electromagnetic waves, boosting the heat put into fusion plasma.
  • Thorium film could replace crystals in atomic clocks of the near future
    Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite some of the fundamental laws of physics. Thorium-229-doped crystals are both scarce and radioactive. A thin film using a dry precursor of thorium-229 shows the same nuclear excitatio...
  • Eyes on the Sun: Naked thallium-205 ion decay reveals history over millions of years
    The Sun generates its tremendous energy through the process of nuclear fusion. At the same time it releases a continuous stream of neutrinos -- particles that serve as messengers of its internal dynamics. Although modern neutrino detectors unveil the Sun's present behavior, significant questions linger about its stability over periods of millions of years. Finding answers to th...
  • Particle research gets closer to answering why we're here
    Physicists have outlined the next 10 years of global research into the behavior of neutrinos, particles so tiny that they pass through virtually everything by the trillions every second at nearly the speed of light.
  • 'Spooky action' at a very short distance: Scientists map out quantum entanglement in protons
    Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton. The results reveal that quarks and gluons, the fundamental building blocks that make up a proton's struc...
  • ODS FeCrAl alloys endure liquid metal flow at 600 °C resembling a fusion blanket environment
    Researchers explored protective coatings to resist corrosion in fusion reactors. They tested -Al2O3 oxide layers on ODS alloys in a high-temperature, flowing lithium-lead environment. Even bare ODS alloys formed a durable -LiAlO2 layer in situ, which suppressed further corrosion. The layers exhibited strong adhesion under mechanical stress, making these findings crucial for imp...
  • Deciphering the anomalous properties of water
    Water, a molecule essential for life, has unusual properties -- known as anomalies -- that define its behavior. However, there are still many enigmas about the molecular mechanisms that would explain the anomalies that make the water molecule unique. Deciphering and reproducing this particular behavior of water in different temperature ranges is still a major challenge for the ...
  • Fermium studied at GSI/FAIR: Researchers investigate nuclear properties of element 100 with laser light
    Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? Researchers report on experiments to come closer to an answer. They gained insight into the structure of atomic nuclei of fermium (element 100) with different numbers of neutrons. Using forefront laser spectroscopy techniques, they traced the evolution of the nucl...
  • Scientists calculate predictions for meson measurements
    Calculations of charge distribution in mesons provide benchmark for experimental measurements and validate widely used 'factorization' method for imaging the building blocks of matter.
  • Imaging nuclear shapes by smashing them to smithereens
    Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC) to reveal subtle details about the shapes of atomic nuclei. The method is complementary to lower energy techniques for determining nuclear structure. It will add depth to scientists' understanding of the nuclei that make up the bulk of visible matter.
  • Successful experiment paves the way for new element
    Scientists have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the world so far: number 120.
  • Molecule 'handedness' determines the strength of a coupling between nuclear spins
    Chirality -- a geometric property that allows molecules to exist in two distinct forms that are chemically identical but are 3D mirror images of each other, like a right and left hand -- has a powerful effect on nuclear spin state but was thought to have no effect on coupling between spins. A study found chirality, or handedness, does in fact determine the strength of a couplin...
  • New AI models of plasma heating lead to important corrections in computer code used for fusion research
    New artificial intelligence models for plasma heating can do more than was previously thought possible, not only increasing the prediction speed 10 million times while preserving accuracy but also correctly predicting plasma heating in cases where the original numerical code failed.
  • Stopping off-the-wall behavior in fusion reactors
    New experimental results suggest that sprinkling boron into a tokamak could shield the wall of the fusion vessel and prevent atoms from the wall from getting into the plasma. A new computer modeling framework shows the boron powder may only need to be sprinkled from one location.
  • Nanopillars create tiny openings in the nucleus without damaging cells
    Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the nucleus' could open new possibilities in gene therapy, where genetic material needs to be delivered directly into the nucleus, as well as drug delivery and other forms of precision...
