  • How do neutron bells toll on the skin of the atomic nucleus? Vibrations of the surface of a heavy nucleus observed
    Physicists have observed -- for the first time with such precision -- vibrations of the surface of a heavy nucleus, lead 208Pb. Through their extremely accurate measurements this team has unraveled the details of neutron oscillations in the atomic nucleus and determined how many neutrons on the surface, or ‘skin’, of the nucleus participate in unique vibrations known as pygmy resonances. If an accelerated ion of high energy impacts on the nucleus of a heavy element, it makes the nucleus vibrate in a very special manner: all of its neutrons begin to oscillate collectively with respect to all of its protons.

  • Unforeseen dioxin formation in waste incineration
    Dioxins forms faster, at lower temperatures and under other conditions than previously thought. This may affect how we in the future construct sampling equipment, flue gas filtering systems for waste incineration and how to treat waste incineration fly ash.

  • Oxides could advance memory devices
    The quest for the ultimate memory device for computing may have just taken an encouraging step forward. Researchers have discovered new complex oxides that exhibit both magnetic and ferroelectric properties.

  • Rooting out horse-meat fraud in the wake of a recent food scandal
    As the United Kingdom forms a new crime unit designed to fight food fraud -- in response to an uproar last year over horse meat being passed off as beef -- scientists are reporting a technique for detecting meat adulteration.

  • Sharks' skin has teeth in the fight against hospital superbugs
    Transmission of bacterial infections, including Methicillin-resistant Staphylococcus aureus and Methicillin-sensitive Staphylococcus aureus could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin, according to research.

  • Recruiting bacteria as technology innovation partners: New self-healing materials and bioprocessing technologies
    For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of 'bad' biofilms around, a team of scientists see biofilms as a robust new platform for designer nanomaterials that could clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more.

  • Nanoribbon film keeps glass ice-free
    Scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies (RF).

  • First water-based nuclear battery can be used to generate electrical energy
    For the first time using a water-based solution, researchers have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight.

  • New halogenation enzyme found: Discovery to impact pharmaceutical and agricultural industries
    One of the Holy Grails in chemical science has been to find the late-stage, site-specific incorporation of a halogen atom into a complex natural product by replacing an sp³ C-H bond -- one of the most inert chemical bonds known in an organic compound -- with a C-X bond, X=halogen.

  • Researchers control surface tension to manipulate liquid metals
    Researchers have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable electronic circuits, antennas and other technologies.
