• Detecting radioactive material in nuclear waste water

    As the Fukushima crisis continues to remind the world of the potential dangers of nuclear disposal and unforeseen accidents, scientists are reporting progress toward a new way to detect the radioactive materials uranium and plutonium in waste water.

  • Using gaming to spark kids' STEM interest, improve physical fitness

    A team of Purdue University technology researchers will use a $1.2 million National Science Foundation grant to tackle two national challenges: increasing children’s interest in science, technology, engineering, and math (STEM); and decreasing childhood obesity. The three-year project parlays kids’ innate interest in video games and solving big problems to inspire them to gain the STEM skills needed to create technology-based fitness games. The project will also encourage students to create exergames that require players to get up and move.

  • New drone to monitor radiation following nuclear disasters

    Researchers have unveiled a large semi-autonomous drone called the ARM system which could be used to provide visual and thermal monitoring of radiation after a release of nuclear material. The system was developed in response to requirements for radiation monitoring in event of the release of radioactive materials.

  • Malaria parasite circumvents natural defense

    Researchers have discovered recent genetic mutations in a parasite that causes over 100 million cases of malaria annually — changes that may render tens of millions of Africans who had been considered resistant, susceptible to infection. The 3-gene mutations appear to be the parasite’s invasion mechanisms. The changes occur in the Plasmodium vivax genome, and the Malaria Atlas Project estimates 2.5 billion people worldwide are at risk for P. vivax malaria.

  • Philippines prepares for worse disasters to come

    On average, the Philippines experiences about twenty typhoons a year, including three super-typhoons and many incidents of flooding, drought, earthquakes, tremors, and occasional volcanic eruptions, making the country one of the most naturally disaster-prone areas in the world. Filipino government agencies, with the help of international disaster and relief agencies, have created new strategies for disaster preparedness, response, and mitigation which may well have potential applications in other parts of the world. As the impact of climate change grows more pronounced, the Philippines is becoming a hothouse for developing new methods and systems in the growing business of disaster relief.

  • Holograms to help in fighting malaria

    Scientists have developed a 3D filming technique that could inform research to stem the spread of malaria. Creating moving digital holograms of malaria sperm has given researchers fresh insights into the behavior of these tiny life forms. Understanding how malaria parasites mate could pave the way for improved prevention and control of this deadly disease, which poses a threat to half of the world’s population.

  • Quick ID for water pathogens

    New research purports to help people stay healthy by developing a real-time water bug testing that could precisely identify the culprits responsible for waterborne disease.

  • Zapping bugs dead

    Restaurants and supermarkets could save millions of dollars by hanging on to bug zapper bulbs instead of tossing them every year as they normally do, a new study has found. What is more, the benefits could extend to the environment by keeping some of the bulbs’ mercury out of the waste stream.

  • DHS, FDA: Decorative contact lenses for Halloween costumes are risky

    Many will celebrate Halloween today, and federal officials are warning the public about the dangers associated with counterfeit decorative contact lenses. Decorative and colored lenses are becoming increasingly popular, especially around this time of year. Several federal agencies have teamed up to launch Operation Double Vision – already underway — to seize illegal, harmful products from store shelves.

  • Where should U.S. radioactive waste be buried?

    In the United States, about 70,000 metric tons of spent commercial nuclear fuel are located at more than seventy sites in thirty-five states. Shales and other clay-rich (argillaceous) rocks have never been seriously considered for holding America’s spent nuclear fuel, but it is different overseas. France, Switzerland, and Belgium are planning to put waste in tunnels mined out of shale formations, and Canada, Japan, and the United Kingdom are evaluating the idea.

  • Sharp increase in radioactive water leaks at Fukushima

    Tokyo Electric Power(TEPCO) has reported a rise in groundwater radiation levels, saying a tank at the firm’s Fukushima plant leaked 300 metric tons of toxic water in August 2013. Water samples from wells, taken in mid-October, show a record-high concentration of beta-ray emitting substances, and a sharp increase in the presence of radioactive tritium. Japanese prime ministerShinzo Abe, in a tacit admission that Japan cannot effectively handle the continuing radiation leaks from the stricken plant, said Japan would be interested in receiving foreign help to contain widening radioactive water leaks at Fukushima.

  • New apps to keep you healthy

    For those wanting to keep their distance from health threats like E. coli-contaminated lettuce or the flu, there are two upcoming apps for that. The Department of Energy’s Pacific Northwest National Laboratory (PNNL) hosted a competition this summer in which graduate students designed two mobile apps to fight the threats of food-related illnesses and the flu. The apps are called FoodFeed and FL•U (pronounced “flu you”).

  • 1930s fight against malaria in U.S. a model for today’s global campaign

    Malaria killed an estimated 1.24 million people worldwide in 2010 and has decimated economies in the heavily populated, warm climate regions. A new study about the elimination of malaria in the 1930s American South may have significant implications for solving modern day malaria outbreaks in parts of Africa, Central and Latin America, and Asia.

  • Iraqi war- and occupation-related death toll estimated at half a million

    A scientific study calculating Iraqi deaths for almost the complete period of the U.S.-led war and subsequent occupation estimates, with 95 percent of statistical certainty, that the total excess Iraqi deaths attributable to the war through mid-2011 to be about 405,000 (“excess” death means death not related to natural causes or causes other than the war and occupation). The researchers also estimated that an additional 56,000 deaths were not counted due to migration. Including this number, their final estimate is that close to half a million people died in Iraq as a result of the war and subsequent occupation from March 2003 to June 2011.

  • Innovative salmonella sensing system

    Foodborne illnesses making one in six Americans — or forty-eight million people — sick each year. Of these people sickened, 128,000 end up in the hospital, according to the Centers for Disease Control and Prevention, while 3,000 die. A new approach to detecting food contamination enables real-time testing of food and processing plant equipment.
