• 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

  • Utah implements harsh triage guidelines for bioterror, epidemic emergencies

    Utah’s new triage health emergency guidelines would see some children and some seniors turned away from hospitals during a bioterror or epidemic emergency; those who are severely burned, have incurable and spreading cancer, fatal genetic diseases, end-stage multiple sclerosis, or severe dementia will be turned away; people older than 85 also would not be admitted in the worst pandemic; those who have signed “do not resuscitate” orders could be denied a bed

  • Is there a connection between ending smallpox vaccination and the explosive spread of HIV?

    Smallpox immunization was gradually withdrawn from the 1950s to the 1970s following the worldwide eradication of the disease, and HIV has been spreading exponentially since approximately the same time; researchers show that vaccinia immunization, given to prevent the spread of smallpox, produces a five-fold reduction in HIV replication in the laboratory; is there a connection between the end of smallpox immunization and the spread of HIV?

  • Workshop to evaluate threat of insect-based terrorism

    One way terrorists may use unleash a bioterror attack on U.S. population centers is by introducing pathogen-infected mosquitoes into an area, then let the insects pursue their deadly mission; many of the world’s most dangerous pathogens — Rift Valley, chikungunya fever, or Japanese encephalitis — already are transmitted by arthropods, the animal phylum that includes mosquitoes

  • Wisconsin researcher punished for unauthorized research on bioterror agent

    A university of Wisconsin researchers conducted unauthorized research on bioterror agent; the researcher developed antibiotic-resistant variants of brucellosis and tested them on mice; the University of Wisconsin was fined $40,000 by the National Institutes of Health, and the professor was ordered to stay out of a lab for five years

  • HIV positive Michigan man fights bioterrorism charge after allegedly biting neighbor

    Daniel Allen of Michigan got into a fight with his neighbor; the neighbor complained that Allen bit him during the fight; when, a few days later, Allen admitted in a TV interview that he was gay and HIV positive, the prosecution charged him with violating Michigan’s bioterrorism law; the prosecution claims that the law’s reference to using a “harmful device” in the commission of bioterror attack may be applied to Allen “use” of his HIV virus as a weapon

  • Faster salmonella strain detection now possible with new technique

    New scientific method identifies salmonella strains much faster than current methods in use; faster detection of specific strains can mean recognizing an outbreak sooner and stopping tainted food from being delivered and consumed

  • Failure to test for six strains of E. coli leaves gaps in U.S. food safety network

    Six E. coli strains are not regulated by the U.S. Department of Agriculture; E. coli O157:H7 causes 73,000 illnesses and 50 deaths every year in the United States; the six other strains are considered less pervasive, sickening an estimated 37,000 people a year and killing nearly 30; they could be causing more illnesses that labs do not detect because they are not testing for them

  • DHS's Fort Detrick biolab about to open

    The new DHS biolab at Fort Detrick, Maryland, is slowly coming to life; the eight-story building has three distinct sections: administrative offices near the front, biosafety level 2 and 3 labs, and then biosafety level 4 labs on the other side of a thick concrete wall; designing the BSL-4 labs as essentially their own building has several benefits; most importantly, a fire or other hazard in the other section of the building wouldn’t require the BSL-4 labs to be frantically evacuated

  • DHS in Manhattan, Kansas, to discuss the National Bio and Agro-Defense Facility

    DHS visits the site of the site of the planned $725 million National Bio and Agro-Defense Facility in Manhattan, Kansas, on the campus of the Kansas State University; DHS officials held a public meeting with Manhattan residents to discuss the new lab

  • Epidemic, bioterrorism study in Las Vegas

    A research project in Nevada looks to help hospitals and public health officials do a better job of quickly identifying the sources and pathways of influenza, E. coli, and other contagious pathogens that can quickly spread through a population; the project will also help in designing ways to cope with a bioterror attack

  • Texas A&M scientist tracks origins of bootleg honey from China

    The United States has imposed a 500 percent tariff on honey from China two years ago because the Chinese government is subsidizing Chinese honey makers so they can drive U.S. producers out of the market; the practice has almost ruined the market for domestic U.S. honey; China is trying to get around the anti-dumping measure by putting labels such as “Product of Thailand” or “Product of Indonesia” on Chinese honey; a Texas A&M honey specialist stands in their way by doing melissopalynology — the study of pollen in honey

  • Former colleague defends Bruce Ivins using back-of-the-envelope math

    A former colleague of Bruce Ivins, who, according to the FBI, was behind the 2001 anthrax attacks in the United States, says the FBI was wrong: it would have taken Ivins at least a year of dedicated work to grow the total amount of anthrax spores contained in the eight letters, and that could not have been done in secrecy; other scientists dispute this assertion

  • Ricin: the most potent -- and readily available -- bioterrorism weapon

    Ricin is of particular concern when it comes to bioterror agents: ricin is not only deadly, but it is also easy to obtain; it is a natural ingredient in the seeds of castor oil plants, which are used in the industrial production of brake fluid, varnish, soap, ink and other products; researchers offer ways to protect human cells from ricin

  • Smart plastic to be used in food packaging to monitor freshness of food

    New type of smart plastic could be used for packaging supermarket products or transporting produce; the new material has sensors embedded in it which will be used for measuring basic parameters such as temperature and humidity and more advanced markers that indicate produce quality; the new smart packaging will also measure the amount of hexanol — an indicator of deterioration in food — in the vapors emitted from foods
