• How serious is the threat of an "EMP Pearl Harbor"?

    In 1962 the United States conducted a high-altitude nuclear test above Johnston Island, 825 miles southwest of Hawaii; detonated 400 kilometers above the island, the resulting nuclear blast knocked out street lights across Hawaii and tripped circuit breakers, triggered burglar alarms, and damaged a telecommunications relay facility on the island of Kauai; could terrorist, or a nuclear-armed rogue state, launch an EMP Pearl harbor against the United States?

  • New college program on food security

    The United States has avoided a major terrorist attack to its food chain, but a small vial of a lethal chemical, such as the nerve toxin ricin, could be introduced anywhere along the chain, injuring thousands directly and, like 9/11, affecting whole industries; Polk State College’s newest program, the Agriculture Business/Technology Institute, will address critical industry issues, including the need for greater security in the food chain

  • FDA's food-safety monitoring in need of overhaul

    A new study of the U.S. food safety regime finds gaping holes in the system; the study finds that shifting to a risk-based food safety system, utilizing a research infrastructure and integrated federal, state, and local government food safety program, can go a long way towards achieving the safer food supply we all desire

  • Cholera spreads in flood-ravaged Pakistan

    With stagnant water throughout Pakistan, water-borne diseases such as gastroenteritis, malaria, and typhoid, now threaten the nation; there are reports of diarrhoea and cholera among the hundreds of thousands left homeless, and food and drinking water are in short supply

  • 3,000 chemical-filled barrels washed into major northeast China river

    Severe floods in China’s Jilin Province carried about 3,000 barrels containing toxic chemicals into the Songhuajiang River in Jilin City; in addition, 4,000 empty barrels containing chemical residues were also washed into the river — a major source of drinking water and fishing; each chemical-filled barrel contains about 170 kilograms of chemicals

  • Radiation concerns dog full-body scanners

    By the end of 2014, TSA will install between 1,950 and 2,200 full-body scanners at checkpoints in all 450 commercial airports in the United States; TSA buys scanners which use two technologies — backscatter X-ray and millimeter wave; since backscatter technology raises persistent worries about radiation, some want to know why TSA should not buy only millimeter-wave scanners

  • Obama heralds Food Safety Act

    President Obama had an organic vegetable garden planted at the White House, and since taking office has been pushing a more aggressive approach to food safety; the administration’s approach is encapsulated in the Food Safety Modernization Act, which would give the U.S. government more effective tools to monitor food safety

  • Media reports influence the severity of pandemics

    Up-to-date media reports about the way an infectious disease is spreading could dramatically reduce the severity of an outbreak, according to a new mathematical model; there is a problem though: if the reports are untrue or exaggerated, then the next pandemic may be deadlier because people may not believe the media reports

  • Scientists: Full-body scanners' radiation underestimated, could pose cancer risk

    More and more scientists express their unease with the amount of radiation to which passengers are exposed as they are screened by full-body scanners at airports; experts say radiation from the scanners has been underestimated and could be particularly risky for children; they say that the low level beam does deliver a small dose of radiation to the body, but because the beam concentrates on the skin — one of the most radiation-sensitive organs of the human body — that dose may be up to 20 times higher than first estimated

  • Bill seeks to bolster U.S. ability to fight bioterror

    Bill calls for bolstering U.S. defenses against future bioterror attacks requiring the director of national intelligence to produce and administer a National Intelligence Strategy for Countering the Threat from WMD, which would be created in consultation with the homeland security secretary as well as other relevant agencies

  • The optimal balance of vaccine stockpiles

    Once a disease has been eradicated there is a danger it could reappear, either naturally or as a result of an intentional release by a terrorist group; how much vaccine should be produced and stored for a disease that may never appear again — or which may infect hundreds of thousands tomorrow? modelers target optimal vaccine storage for eradicated diseases

  • Botox as a bioterror threat

    Botox may be used to straighten wrinkles and lift sagging body parts, but the proliferation of counterfeit Botox worldwide — fueled by consumer demand — has made the toxin, which is deadly in sufficient quantities, far more easily available for would-be bioterrorists than it was in the past

  • Video study finds risky food-safety behavior more common than thought

    New study finds that that risky practices in restaurants, cafeterias, and other food-service places happen more often than previously thought; one expert says: “Meals prepared outside the home have been implicated in up to 70 percent of food poisoning outbreaks, making them a vital focus area for food safety professionals”

  • New method manipulates particles for sensors, crime scene testing

    Researchers develop a new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics; the technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses, and DNA, which are contained inside the drops

  • Dengue fever strikes United States after 65-year absence

    After an absence of sixty-five years, dengue fever has reentered the United States through the Florida Keys; the CDC reports that twenty-eight people in Key West came down with the dangerous fever; infected mosquitoes have been moving northward thanks to global warming, and there has been increased travel between the United States and South and Central America and the Caribbean — areas which have seen nearly five million cases of dengue fever from 2000 to 2007
