    Materials emitted by a water pipe repair method may pose health risks, new safeguards and research needed

    Original @ Phys.org – latest science and technology news stories New research is calling for immediate safeguards and the study of a widely used method for repairing sewer, stormwater and drinking water pipes to understand the potential health and environmental concerns for workers and the public. [...]

    Seeing the light: Researchers seek to improve solar cell technology using new materials and nanowires

    Original @ Phys.org – latest science and technology news stories Researchers at Rochester Institute of Technology are expanding solar cell technology using nanowires to capture more of the sun’s energy and transform it into usable electricity. Comparable to ultra-thin blades of grass, nanowires added to today’s conv… [...]

    Ultracold molecules hold promise for quantum computing

    Original @ Phys.org – latest science and technology news stories Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new work shows that collections … [...]

    Fundamental breakthrough in the future of designing materials

    Original @ Phys.org – latest science and technology news stories A team of researchers from AMBER centre based in Trinity College Dublin, have made a breakthrough in the area of material design – one that challenges the commonly held view on how the fundamental building blocks of matter come together to form materials. [...]

    Reality check for topological insulators

    Original @ Phys.org – latest science and technology news stories Topological insulators, a class of materials which has been investigated for just over a decade, have been heralded as a new ‘wonder material”, as has graphene. But so far, topological insulators have not quite lived up to the expectations fueled by th… [...]

    Regulation of two-dimensional nanomaterials for lithium-ion batteries

    Original @ Phys.org – latest science and technology news stories Li-ion batteries (LIBs) are advantageous energy storage devices due to their higher specific energy density, lower self-discharge, and lower memory effect. Among the components of batteries, electrode materials play a key role in enhancing electrochemi… [...]

    Somersaulting simulation for jumping bots

    Original @ Phys.org – latest science and technology news stories In recent years engineers have been developing new technologies to enable robots and humans to move faster and jump higher. Soft, elastic materials store energy in these devices, which, if released carefully, enable elegant dynamic motions. Robots leap… [...]

    Longer-lasting fragrance is just a shampoo away, thanks to peptides

    Original @ Phys.org – latest science and technology news stories Many people select their shampoo based on smell. Unfortunately, that scent usually doesn’t last long on hair. Now, one team reports in ACS Applied Materials & Interfaces a new way to help the fragrance “stick” to hair longer. [...]

    User research at BER II: Lupin roots observed in the act of drinking

    Original @ Phys.org – latest science and technology news stories Lupins produce colourful blossoms and nutritious beans. Just how these plants draw water has now for the first time been observed in three dimensions by a University of Potsdam team at the HZB-BER II neutron source in Berlin. They improved the temporal… [...]

    How genetically engineered viruses develop into effective vaccines

    Original @ Medical Xpress – latest medical and health news stories Lentiviral vectors are virus particles that can be used as a vaccine to stimulate the immune system to fight against specific pathogens. The vectors are derived from HIV, rendered non-pathogenic, and then engineered to carry genetic material into the body’s immune cells; the genes program the cells to fight specific pathogens. New research from the laboratory of David Baltimore, president emeritus and the Robert Andrews Millikan Professor of Biology, shows that additional materials acquired during the vector’s formation—namely, proteins and human genomic DNA—play an important role in activating the immune system. Understanding how lentiviral vectors interact with the immune system is critical to improving vaccines so as to maximize the immune response, and to understanding infectious processes occurring in natural pathogens.
