• 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

  • Michigan biter did not violate bioterrorism laws

    A judge dismissed bioterrorism charges against an HIV-positive Michigan man who bit his neighbor during a fight; the prosecution argued that the defendant intended to infect the neighbor with the virus, thus violating Michigan bioterrorism laws

  • Researchers develop an Ebola vaccine

    Researchers develop an experimental vaccine that cures the Ebola virus by targeting its genetic material; trouble is, the Ebola vaccine can only work if it is administered within thirty minutes, which is an impracticality among civilian populations; the vaccine is a viable possibility within a research facility, so it may be used to protect the researchers themselves

  • 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

  • Defeating anthrax bacterium's natural defenses may hold key to new treatments

    Up to 90 percent of untreated cases of inhalational anthrax result in death; Bacillus anthracis, the causative agent of anthrax, is particularly lethal because of its protective coating, or capsule, which enables the pathogen to escape destruction by the host’s immune system; researchers discover a way to “trick” the bacterium into shedding its protective covering

  • 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
