  • Where no smartphone has gone before
    Star Trek's 'Tricorder' was an essential tool, a multifunctional hand-held device used to sense, compute, and record data in a threatening and unpredictable universe -- and it's no longer completely science fiction. A new invention may be able to turn smartphones into powerful hyperspectral sensors, capable of identifying the chemical components of objects from a distance.

  • New pain relief delivery method discovered
    A new drug release gel, which may help avoid some of the side effects of painkillers such as ibuprofen and naproxen, has been developed by chemists looking for a way of eliminating the adverse side-effects associated pain-killing drugs, particularly in the stomach. The new gel, based on small molecules which self-assemble into nanofibers which could interact with a variety of anti-inflammatory, painkiller drugs, including iburofen and naproxen, they say.

  • How to make a profit from rotting garbage
    Landfills can make a profit from all their rotting waste and a new patent explains exactly how to make the most out of the stinky garbage sites. Decomposing trash produces methane, a landfill gas that can be used to produce electricity or heat. Since methane is a greenhouse gas and most landfills don't produce enough of it to make energy production worthwhile, many dumpsites burn, or flare, the methane away so that the harmful gas does not escape into the atmosphere. But a new process shows how landfills can up their methane production to turn a profit.

  • An efficient path from carbon to renewable fuel production
    Earth-abundant materials based primarily on carbon, nitrogen and transition metal oxides can be combined into highly efficient energy conversion devices. These devices can be used in fuel cells as well as in electrolysis.

  • New imaging tool targets degenerative diseases
    Figuring out what's happening at a cellular and molecular level may help scientists develop ways to treat or prevent age-related, neurogenerative diseases, such as Alzheimer's and Parkinson's. Researchers have developed the first imaging reagent that can determine thiol levels in intact living cells. Now they are working on reagents that can selectively show thiol density in subcellular structures, specifically the nucleus and mitochondria, hoping to develop a nontoxic reagent safe enough to be used for diagnostic imaging, like an MRI.

  • Wrapping carbon nanotubes in polymers enhances their performance
    Scientists say polymer-wrapped carbon nanotubes hold much promise in biotechnology and energy applications.

  • Thin transparent flexible screens: Roll up your screen and stow it away?
    As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices -- especially computer displays that can be easily rolled up and stored or transported. A new study suggests that a novel DNA-peptide structure can be used to produce thin, transparent, and flexible screens. The research harnesses bionanotechnology to emit a full range of colors in a single pliable pixel layer.

  • Recipe for antibacterial plastic: Plastic plus egg whites
    Bioplastics made from protein sources such as albumin and whey have shown significant antibacterial properties, findings that could eventually lead to their use in plastics used in medical applications such as wound healing dressings, sutures, catheter tubes and drug delivery, according to a recent study. The bioplastic materials could also be used for food packaging.

  • Nanoscale worms provide new route to nano-necklace structures
    Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

  • Bacteria can use magnetic particles to create a 'natural battery'
    New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to new work, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications.
