• Researchers developing wireless emergency network for disasters

    University of Arkansas researchers are developing a solar powered wireless emergency communications network that can be deployed during major disasters to transmit critical warnings and geographic information

  • Killer silk kills anthrax, other microbes dead

    A simple, inexpensive dip-and-dry treatment can convert ordinary silk into a fabric that kills disease-causing bacteria — even the armor-coated spores of microbes like anthrax — in minutes

  • Harvesting energy, water from human waste

    Researchers begin developing prototype device for harvesting energy and clean drinking water from human waste; the device proposal beat more than 2,000 other proposals to receive funding from the Bill and Melinda Gates Foundation

  • Rethinking the toilet model in developing countries

    More than 2.6 billion people around the world lack access to basic sanitation, and more than 40 percent of the world’s population lack access to even the simplest latrine; the lack of sanitation creates serious problems, including environmental pollution, unsafe surroundings, and increasing the outbreak of lethal epidemic diseases such as cholera; Swedish company offers a solution

  • Researcher develops highly sensitive, nanomaterial gas detector

    A doctoral student at the Rensselaer Polytechnic Institute has developed a new sensor to detect extremely small quantities of hazardous gas

  • Universal Detection unveils radiation detection smartphone app

    Last week Universal Detection Technology unveiled its first generation smartphone app designed to detect nuclear radiation levels on a variety of surfaces including food

  • New paper gas detectors developed

    Researchers at the University of Michigan, Ann Arbor, have developed a quick and simple way to detect the presence of nerve gases

  • Origami-inspired paper sensor tests for malaria, HIV for less than 10 cents

    Chemists have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than ten cents a pop; such low-cost, point-of-care sensors could be useful in the developing world, where the resources often do not exist to pay for lab-based tests, and where, even if the money is available, the infrastructure often does not exist to transport biological samples to the lab

  • Computer spots liars by looking at the way they talk

    Computer scientists are exploring whether machines can read the visual cues of an individual’s conduct to discover whether or not that individual is lying; in a study of forty videotaped conversations, an automated system the researchers developed correctly identified whether interview subjects were lying or telling the truth 82.5 percent of the time

  • Robot for shipboard firefighting

    In both war and peace, fire in the shipboard environment is serious and frequently results in excessive damage and high repair costs because the fire is not detected or controlled adequately; researchershave developed a humanoid robot that could fight fires on the next generation of combatants

  • National Academies calls for expanded nuclear-fusion research

    A report out on Wednesday from the National Academies says university researchers studying nuclear fusion still have a long way to go before overcoming the many scientific hurdles to the commercial generation of what is hoped to be a virtually limitless supply of energy

  • Solving the major problem of renewable energy: intermittency

    Intermittency, sometimes called the Achilles’ heel of renewable energy, has so far limited the penetration of renewable sources in most power grids; engineers imagine an energy future where giant transmission grids are backed up by massive energy storage units

  • Company develops telephone line “fingerprint” detector

    Researchers at Pindrop, a new security company, have developed technology that can read telephone line “fingerprints” to prevent fraud and identify a caller

  • Pasta-shaped radio waves beamed across Venice

    One solution to communication congestion during emergencies is to create a public safety-dedicated band of the spectrum, allowing for a unified and uninterrupted communication among first responders; another solution is twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received

  • Poultry feathers-based filters remove arsenic from water

    Thousands of people die each year in developing countries from drinking arsenic-contaminated water; researchers develop inexpensive filters made from the modified protein (keratin) in poultry feathers to remove arsenic from drinking water
