  1. Protein mingling under blue light
    One of the current challenges in biology is to understand rapidly-changing phenomena. Interestingly, only a small fraction of them is due to proteins acting in isolation, the majority of biological events are regulated by proteins acting together in clusters. Researchers have developed a new tool, called "CRY2clust", to trigger protein cluster formation in response to blue light. This new technique has a much faster response rate and higher sensitivity to light than existent methods.
  2. Deceleration of runaway electrons paves the way for fusion power
    Fusion power has the potential to provide clean and safe energy that is free from carbon dioxide emissions. However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists have now taken us one step closer to a functional fusion reactor. Their model could lead to better methods for decelerating the runaway electrons, which could destroy a future reactor without warning.
  3. Zig-zagging device focuses high-energy radiation emissions
    Equipment used in cancer treatment requires a strong, monochromatic source of radiation to produce hard X-rays. Other similar radiation sources find applications in nuclear waste processing. To design devices that steadily emit a specific type of radiation, physicists use a special kind of crystal, referred to as a crystalline undulator. Scientists have now demonstrated the ability to control radiation emissions from a particle traveling through such a device.
  4. Physicists use numerical 'tweezers' to study nuclear interactions
    Researchers have developed numerical 'tweezers' that can pin a nucleus in place, enabling them to study how interactions between protons and neutrons produce forces between nuclei.
  5. Study improves remote detection of hazardous radioactive substances
    A new method has been proposed that might be used to detect nuclear hazards from up to a few hundred meters away.
  6. Diagnostic radiation exposure safe for children, experts state
    Exposure to medical imaging radiation not only doesn't increase an adult person's risk of getting cancer, it doesn't increase a child's risk. Researchers state that the long-held belief even low doses of radiation, such as those received in diagnostic imaging, increase cancer risk is based on an inaccurate, 70-year-old hypothesis and leads to unnecessary fear and misdiagnoses.
  7. New-generation material removes iodine from water
    New material scrubs iodine from water for the first time and could hold the key to cleaning nuclear accidents.
  8. Low cost, scalable water splitting fuels the future hydrogen economy
    An efficient, low-cost catalyst could replace platinum in water-splitting for clean hydrogen production.
  9. Heavy particles get caught up in the flow
    By teasing out signatures of particles that decay just tenths of a millimeter from the center of a trillion-degree fireball that mimics the early universe, nuclear physicists smashing atoms at the Relativistic Heavy Ion Collider (RHIC) are revealing new details about the fundamental particles that make up our world.
  10. Real-time monitoring of irradiated materials
    Researchers have developed a much faster, non-contact method of studying how materials change in a high-radiation environment, such as inside a nuclear reactor.
  11. US nuclear regulators greatly underestimate potential for nuclear disaster
    The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to a recent article. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages.
  12. Atomic structure of irradiated materials is more akin to liquid than glass
    Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material's atoms, which then collide with each other. The resulting disordered atomic network resembles those seen in some glassy materials, which has led many in the field to use them in nuclear research. But the similarities between the materials may not be as useful as previously thought.
  13. In a neutron-rich tin nucleus, electromagnetism can win over the strong force
    The atomic nucleus offers a unique opportunity to study the competition between three of the four fundamental forces known to exist in nature, the strong nuclear interaction, the electromagnetic interaction and the weak nuclear interaction. Only the much weaker gravitational force is irrelevant for the description of nuclear properties. Although in general the decay of an excited nuclear state follows the hierarchy of these forces, there are sometimes exceptions.
  14. Scientists perform first basic physics simulation of spontaneous transition of the edge of fusion plasma to crucial high-confinement mode
    Physicists have simulated the spontaneous transition of turbulence at the edge of a fusion plasma to the high-confinement mode that sustains fusion reactions. The research was achieved with the extreme-scale plasma turbulence code XGC.
  15. Public divides over environmental regulation and energy policy
    A 54 percent majority of US adults believe that 'government regulations are necessary to encourage businesses and consumers to rely more on renewable energy sources,' while 38 percent support the notion that 'the private marketplace will ensure that businesses and consumers rely more on renewable energy sources, even without government regulations,' according to a new survey.
  16. Energy decay in graphene resonators
    Researchers have observed a new way of energy dissipation in graphene nano-resonators, outlines a new report.
  17. New model of plasma stability could help researchers predict and avoid disruptions
    Physicists have helped develop a new computer model of plasma stability in doughnut-shaped fusion machines known as tokamaks. The new model incorporates recent findings gathered from related research efforts and simplifies the physics involved so computers can process the program more quickly. The model could help scientists predict when a plasma might become unstable and then avoid the underlying conditions.
  18. New plutonium discovery lights way for chemistry professor's work to clean up nuclear waste
    A chemistry professor created a plutonium compound that behaves much more like lighter elements, giving scientists new information about how this element works.
  19. Experiment designed to detail inner workings of strong force inside matter reports its first data
    New result demonstrates the feasibility of the experiment that is designed to study quark confinement: why no quark has ever been found alone.
  20. Aquatic rest stops may pose potential hazards for migratory waterfowl
    Migratory waterfowl around the world travel hundreds to thousands of miles annually, stopping at lakes, ponds and marshes to refuel and breed. Some of these aquatic rest stops may be at sites polluted by remnants of radioactive waste from nuclear production or accidents, exposing the birds to contamination that they take with them. This poses a potential risk to humans if the waterfowl enter the food chain.
  21. New discovery could aid in detecting nuclear threats
    A new way to detect nuclear materials has been developed by researchers. Made of graphene and carbon nanotubes, the researchers' detector far outpaces any existing one in its ultrasensitivity to charged particles, minuscule size, low-power requirements, and low cost.
  22. New material could save time and money in medical imaging and environmental remediation
    Chemists have developed a material that holds the key to cheap, fast and portable new sensors for a wide range of chemicals that right now cost government and industries large sums to detect.

    A new article describes how heating core of the plasma can create sheared flow that improves stability and performance of fusion devices.
  25. New measurements suggest ‘antineutrino anomaly’ fueled by modeling error
    Results from a new study could explain a mismatch between predictions and recent measurements of ghostly particles streaming from nuclear reactors -- the so-called “reactor antineutrino anomaly” that has puzzled physicists since 2011.
