• 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

  • Wooden or plastic pallets are a dangerous link in food chain

    Pallets are often stored in warehouses or outside behind grocery stores, where they are easily reached by debris from garbage or bacteria from animals; new sanitation tests found that about 33 percent of the wooden pallets it tested showed signs of unsanitary conditions, where bacteria could easily grow; 10 percent tested positive for e. coli, which can cause food poisoning, and 2.9 percent had an even nastier, and often deadly, bug called listeria

  • Coral snake antivenin to run out in October

    If you live in Florida, you should now be doubly careful not to be bitten by the poisonous coral snake; the only company making antivenin for coral snake bites is no longer producing the drug — and the last batch will hit its expiration date in October.

  • Safer food imports goal of public-private venture

    With imports accounting for 15 percent of the U.S. food supply, the United States needs a better way of ensuring food safety than border inspections; the University of Maryland teams up with a Massachusetts company to launch training center for foreign foodproducers

  • Food-labels contaminate food

    Chemicals used in adhesive which is used to attach food labels to packaging can seep through packaging and contaminate food; one of those chemicals is considered highly toxic and found in high concentration in some adhesives

  • Katrina, Rita cleaned up polluted, lead-laden New Orleans soil

    It appears that hurricanes Katrina and Rita, with all the devastation they have caused, made one beneficial contribution to the future of New Orleans: decades of Louisiana-type corruption and collusion between the oil industry and the state government have caused the city’s soil to be heavily polluted, laden with lead, arsenic, and other poisonous substances; the sediments washed into the city by the hurricanes have blanketed the polluted soil, resulting in a dramatic drop in the presence of lead and arsenic in the city’s soil — and in the blood stream of children in the city
