  • Energized fabrics could keep soldiers warm and battle-ready in frigid climates
    on August 20, 2017 at 11:50 am

    Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating, while hands and feet can grow numb. To keep military personnel more comfortable, scientists are trying to create high-tech fabrics that heat up when powered and that capture sweat. These fabrics could conceivably be used in future consumer clothing. […]

  • Detecting a concealed weapon or threat is not easy, even for experienced police officers
    on August 15, 2017 at 4:14 pm

  • Quantum probes dramatically improve detection of nuclear spins
    on July 3, 2017 at 2:13 pm

    Researchers have demonstrated a way to detect nuclear spins in molecules noninvasively, providing a new tool for biotechnology and materials science. Important research in medicine and biology relies on nuclear magnetic resonance (NMR) spectroscopy, but until now, it has been limited in spatial resolution and typically requires powerful microwave fields. Scientists have now used a quantum probe to perform microwave-free NMR at the nanoscale. […]

The experiment has used the world-leading capabilities of the beamline to investigate the hydration of cements used by the nuclear industry for the storage and disposal of waste. […]

  • Breakthrough in nuclear threat detection science
    on June 29, 2017 at 3:28 pm

    Taking inspiration from an unusual source, a research team has dramatically improved the science of scintillators -- objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials through America's ports and borders. […]

  • Neutron-rich nucleus shapeshifts between a rugby ball and a discus
    on June 23, 2017 at 2:04 pm

    There are two coexisting, competing quantum shapes at low energy in 98Kr, never before seen for neutron-rich Kr isotopes, report scientists. The team also showed that these isotopes experience a gentle onset of deformation with added neutrons, in sharp contrast with neighboring isotopes of rubidium, strontium, and zirconium, which change shapes suddenly at neutron number 60. This study marks a decisive step towards an understanding of the limits of this quantum phase transition region. […]

  • Bacteria free themselves with molecular 'speargun'
    on June 16, 2017 at 12:37 pm

    Many bacteria are armed with nano-spearguns, which they use to combat unwelcome competitors or knockout host cells. The pathogen responsible for tularemia, a highly virulent infectious disease, uses this weapon to escape from its prison in cells defending the host, report researchers. […]

  • New fabric coating could thwart chemical weapons, save lives
    on June 7, 2017 at 4:39 pm

    Chemical weapons are nightmarish. In a millisecond, they can kill hundreds, if not thousands. But, in a study, scientists report that they have developed a way to adhere a lightweight coating onto fabrics that is capable of neutralizing a subclass of these toxins -- those that are delivered through the skin. The life-saving technique could eventually be used to protect soldiers and emergency responders. […]

  • US nuclear regulators greatly underestimate potential for nuclear disaster
    on May 25, 2017 at 6:15 pm

    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. […]

  • Your mobile phone can reveal whether you have been exposed to radiation
    on May 24, 2017 at 6:03 pm

    In accidents or terror attacks which are suspected to involve radioactive substances, it can be difficult to determine whether people nearby have been exposed to radiation. But by analysing mobile phones and other objects which come in close contact with the body, it is possible to retrieve important information on radiation exposure. […]

  • Atomic structure of irradiated materials is more akin to liquid than glass
    on May 23, 2017 at 4:42 pm

    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. […]

  • In a neutron-rich tin nucleus, electromagnetism can win over the strong force
    on May 19, 2017 at 12:38 pm

    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. […]

  • Visualizing nuclear radiation
    on March 22, 2017 at 1:23 pm

    Extraordinary decontamination efforts are underway in areas affected by the 2011 nuclear accidents in Japan. The creation of total radioactivity maps is essential for thorough cleanup, but the most common methods do not 'see' enough ground-level radiation. […]

  • Nuclear Regulation: Safety is valued too low, research review shows
    on February 3, 2017 at 4:01 pm

    The benchmark used by the Office for Nuclear Regulation for judging how much should be spent on nuclear safety has no basis in evidence and places insufficient value on human life, suggests a new paper. The review suggests it may need to be 10 times higher -- between £16 million and £22 million per life saved. […]
