• 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.

  • Burping for power: Tapping cow burps for natural gas

    Scientists in Argentina have developed a method to transform the gas created by cows’ digestive systems into fuel. The technique channels the digestive gases from bovine stomach cavities through a tube and into a tank, where the gases, called eruptos (burps) in Spanish, are processed to separate methane from other gases such as carbon dioxide.

  • More than 500 million people could face increasing water scarcity

    Both freshwater availability for many millions of people and the stability of ecosystems such as the Siberian tundra or Indian grasslands are put at risk by climate change. Even if global warming is limited to 2 degrees above pre-industrial levels, 500 million people could be subject to increased water scarcity.

  • 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.

  • Small changes in agricultural practices reduce produce-borne illness

    Foodborne illness sickens an estimated 9.4 million and kills around 1,300 annually in the United States, according to the Centers for Disease Control and Prevention. Produce accounts for nearly half the illnesses, and 23 percent of the deaths. Researchers have identified some agricultural management practices in the field that can either boost or reduce the risk of contamination in produce from two major foodborne pathogens: salmonella, the biggest single killer among the foodborne microbes, and Listeria monocytogenes.

  • Physicians feared terrorists might hack Dick Cheney’s cardiac defibrillator

    In a 60 Minutes segment aired yesterday (Sunday), former vice-president Dick Cheney told the interviewer that his doctors turned off the wireless function of his implanted cardiac defibrillator (ICD) “in case a terrorist tried to send his heart a fatal shock.” Asked about the concern of Cheney’s physicians, electrophysiologists — these are the cardiologists who implant ICDs – say that as far as they know, this has never happened in the real world but that it is impossible to rule out the possibility.

  • 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.

  • One in 2,000 people in the U.K. carry mad cow disease proteins

    Variant Creutzfeldt-Jakob disease (vCJD) is a degenerative brain disease — often called the human form of bovine spongiform encephalopathy (BSE) or “mad cow disease.” It emerged after widespread exposure to BSE prions in the late 1980s and early 1990s through contaminated meat products in the food chain. Around one in 2,000 people in the United Kingdom may carry variant CJD proteins, concludes a large scale survey published on BMJ.

  • Compound derived from vegetables offers shield from lethal radiation doses

    Researchers say a compound derived from cruciferous vegetable such as cabbage, cauliflower, and broccoli protected rats and mice from lethal doses of radiation. The compound, known as DIM could protect normal tissues in patients receiving radiation therapy for cancer, but could also protect individuals from the lethal consequences of a nuclear disaster.

  • Innovative device speeds up food-pathogen detection

    Researchers have developed a system that concentrates foodborne salmonella and other pathogens faster than conventional methods by using hollow thread-like fibers that filter out the cells, representing a potential new tool for speedier detection. The machine, called a continuous cell concentration device, could make it possible to routinely analyze food or water samples to screen for pathogens within a single work shift at food processing plants.

  • ASCB: U.S. scientific research will "pay dearly" for shutdown

    The American Society for Cell Biology (ASCB) added its voice to those of other scientific and professional groups in warning that the federal government’s partial shutdown will hurt patients, researchers, and especially the U.S. research effort, long after an agreement to end the impasse is reached. “As America keeps hitting the brakes on scientific research, we are, in effect, accelerating the damage done to our continued leadership in global bioscience, in health outcomes and in the economic power that we have always derived from basic research,” Dr. Bertuzzi, executive director of the ASCB said. “Americans will pay dearly for these slowdowns, sequestrations, and shutdowns in finding cures and on maintaining economic competitiveness.”

  • Compact, high-power terahertz source at room temperature developed

    Terahertz (THz) radiation — radiation in the wavelength range of 30 to 300 microns — is gaining attention due to its applications in security screening, medical and industrial imaging, agricultural inspection, astronomical research, and other areas. Traditional methods of generating terahertz radiation usually involve large and expensive instruments, some of which also require cryogenic cooling. Researchers have developed a compact, room-temperature terahertz source with an output power of 215 microwatts.
