  1. Research elucidates why protons are at the heart of atoms spin
    A major new finding about the fundamental structure of all matter has just been published. The research stems from an analysis of data produced by an experiment in polarized proton-proton collisions.
  2. Speeding the development of fusion power to create unlimited energy on Earth
    A new paper offers a detailed examination of the challenges and tradeoffs in the development of a compact fusion facility with high-temperature superconducting magnets.
  3. Tied in knots: New insights into plasma behavior focus on twists and turns
    Findings from an international team of scientists show that twisted magnetic fields can evolve in only so many ways, with the plasma inside them following a general rule.
  4. Investigation of the origin of heavy elements
    Atomic physicists working on nuclear fusion research succeeded in computing the world's highest accuracy atomic data of neodymium ions which is used in analysis of the light from a binary neutron star merger. This research accelerates studies of a long-standing mystery about the cosmic origins of heavy elements.
  5. Researchers turn liquid metal into a plasma
    Researchers have found a way to turn a liquid metal into a plasma and to observe the temperature where a liquid under high-density conditions crosses over to a plasma state. Their observations have implications for better understanding stars and planets and could aid in the realization of controlled nuclear fusion -- a promising alternative energy source whose realization has eluded scientists for decades.
  6. Shifting away from coal is key to cutting greenhouse gas emissions
    The United States could fulfill its greenhouse gas emission pledge under the Paris Climate Agreement by virtually eliminating coal as an energy source by 2024, according to new research.
  7. In-depth insights into glass corrosion
    Silicate glass has many applications, including the use as a nuclear waste form to immobilize radioactive elements from spent fuel. However, it has one disadvantage -- it corrodes when it comes into contact with aqueous solutions. Scientists were able to observe in detail which processes take place.
  8. How cosmic events give insight into fundamental properties of matter
    The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high temperatures and densities in the merger scientists conjecture a phase-transition where neutrons dissolve into their constituents: quarks and gluons.
  9. Puzzling sizes of extremely light calcium isotopes
    Researchers have measured for the first time the nuclei of three proton-rich calcium isotopes.
  10. New measurements of exotic form of magnesium suggest surprising shape-shift
    An international team led by scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has reproduced an exotic form of magnesium, known as magnesium-40, and gleaned new and surprising clues about its nuclear structure.
  11. Quantum sensors providing magnetic resonance with unprecedented sensitivity
    Scientists have produced a series of protocols for quantum sensors that could allow images to be obtained by means of the nuclear magnetic resonance of single biomolecules using a minimal amount of radiation.
  12. Quantum structure of buckyballs
    Researchers have measured hundreds of individual quantum energy levels in the buckyball, a spherical cage of 60 carbon atoms. It's the largest molecule that has ever been analyzed at this level of experimental detail in the history of quantum mechanics. Fully understanding and controlling this molecule's quantum details could lead to new scientific fields and applications, such as an entire quantum computer contained in a single buckyball.
  13. Fast action: Novel device may rapidly control plasma disruptions in a fusion facility
    Feature describes prototype of new device that mitigates disruption of fusion plasmas faster than the most developed techniques today.
  14. Enhanced NMR reveals chemical structures in a fraction of the time
    Researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.
  15. Fiery sighting: A new physics of eruptions that damage fusion experiments
    Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called 'edge localized modes (ELMs),' occur in doughnut-shaped tokamak devices that house the hot, charged plasma that is used to replicate on Earth the power that drives the sun and other stars. Now researchers have directly observed a possible and previously unknown process that can trigger damaging ELMs.
  16. Scientists discover a process that stabilizes fusion plasmas
    New research describes a newly discovered stabilizing effect of an underappreciated 1983 finding that variations in plasma temperature can influence the growth of magnetic islands that lead to disruption of fusion plasmas.
  17. Precision experiment first to isolate, measure weak force between protons, neutrons
    A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron and one proton for the study. Through a unique neutron experiment, experimental physicists resolved the weak force between the particles at the atom's core, predicted in the Standard Model that describes the elementary particles and their interactions.
  18. The coming of age of plasma physics
    The story of the generation of physicists involved in the development of a sustainable energy source, controlled fusion, using a method called magnetic confinement.
  19. Proton scattering reveals the secrets of strongly-correlated proton-neutron pairs in atomic nuclei
    An international research collaboration has reported the first experimental evidence that the strongly correlated proton-neutron pairs found in an atomic depend on nuclear structure. The experiment, conducted on a new beam line at the Osaka cyclotron facility, demonstrated the dominance of tensor interactions in the neutron pickup reaction. It is hoped that the findings will improve our understanding of neutron stars and other celestial bodies.
  20. System monitors radiation damage to materials in real-time
    A new system allows detailed real-time observations of how materials are affected by a high-radiation environment. The system could accelerate the development of better materials for nuclear plants.
