• Effective screening of airline passengers arriving from areas of infectious disease outbreaks

    New study shows that exit-screening at thirty-six airports would have assessed all air travelers at risk of transporting H1N1 out of Mexico at start of 2009 pandemic. Screening at 99 percent of the world’s international airports could have been forgone with negligible missed opportunities to prevent or delay the spread of disease. Screening at just eight airports worldwide would have led to the assessment of 90 percent of all at-risk air travelers.

  • Lawmakers criticize FDA, CDC for Cyclospora outbreak foot-dragging

    Lawmakers want to know why it has taken so long for food-safety authorities to respond to the cyclospora outbreak which, so far, has sickened at least 418 people in sixteen states. They also want to know why the FDA and CDC have been tight-lipped about the specific products carrying the parasite — health authorities in Nebraska and Iowa have pointed to bagged salad containing romaine and iceberg lettuce as well as carrots and cabbage as the source – and who is the manufacturer of the contaminated products.

  • New journal articles offer useful information for farmers, soldiers

    A new study of the Research Program for Deployed Warfighter Protection (DWFP) program discusses the program’s accomplishments, including the rodent feed-through technique with insecticidal baits for controlling phlebotomine sand flies; developing attractive targeted sugar bait for use against mosquitoes and sand flies; developing a lethal oviposition trap for container-breeding mosquitoes and evaluating using pyriproxyfen (an insect growth regulator) and autodissemination by these mosquitoes to block their reproduction and metamorphosis; defining the limitations of insect repellents against infected vectors; and developing the Florida Fly Baiter and several types of novel sprayer equipment for insecticide application.

  • CDC warns of parasites-related illnesses in fifteen states

    The Center for Disease Control and Prevention (CDC) announced on Monday that the number of Cyclospora cases has risen to 373 in fifteen states. State and federal health officials have not named the food or water source responsible for to the outbreak, but fresh produce is the likely source.

  • Tick rover robot kills ticks dead

    The day may not be too far away when homeowners can schedule monthly tick clearing service, drastically reducing the risk of tick-borne illness in their pets and children. This is because the “tick rover” robot has just cleared a major hurdle. Testing last month indicated unequivocally that the device kills between 75 and 100 percent of the ticks in its path.

  • Natural pest control protein for fighting hookworm: billion to benefit

    Hookworms, and other intestinal parasites known as helminths infect more than one billion people in poverty-stricken, tropical nations, sucking the vitality from the body, and leaving hundreds of millions of children physically and mentally stunted. A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms.

  • Mass religious gatherings in Middle East increase risk of MERS coronavirus spreading globally

    Researchers say that the life-threatening MERS coronavirus which has emerged in the Middle East could spread faster and wider during two international mass gatherings involving millions of people in the next few months – the umrah pilgrimage and the hajj. The researchers describe the most likely pathways of international spread based upon worldwide patterns of air travel.

  • U.K. water industry: fracking may contaminate U.K. drinking water

    U.K. water companies have warned the shale gas industry that the quality of U.K. drinking water must be protected at all costs and fracking must not harm public health. Shale gas fracking could lead to contamination of the water supply with methane gas and harmful chemicals if not carefully planned and carried out.

  • New way found to battle mosquitoes carrying diseases

    In the global war against disease-carrying mosquitoes, scientists have long believed that a single molecular door was the key target for insecticide. This door, however, is closing, giving mosquitoes the upper hand. In a study published this week, a team of researchers has discovered a second gateway that could turn the tide against the mosquitoes’ growing advantage.

  • Researchers highlight problem of legacy mercury in the environment

    Researchers have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

  • Radiation dose passengers receive from airport scanners is low

    An independent task force examining X-ray backscatter scanners at LAX airport determines that that people absorb less radiation from airport X-ray backscatter scanner than they do while standing in line waiting for the scan.

  • FDA shuts down more than 1,500 online pharmacies

    The U.S. Food and Drug Administration (FDA) and Interpol have shutdown 1,677 online pharmacies for selling counterfeit or substandard medication and selling drugs without the necessary safeguards.

  • FDA warns about vulnerability of medical devices to hacking

    The Food and Drug Administration (FDA) has warned manufactures of medical devices implanted into the human body, such as pacemakers and insulin pumps, to step up their cybersecurity efforts. The agency said it has discovered “cybersecurity vulnerabilities and incidents that could directly impact medical devices or hospital network operations.”

  • FDA-approved medications may stop deadly ebola

    Ebola infections carry fatality rates of up to 90 percent. It strikes both humans and other primates, and there are fears it could be used as a biological weapon. There is no cure. New research suggests that a class of drugs that includes treatments for breast cancer and infertility appears able to inhibit the deadly, incurable Ebola virus.

  • New microfluidic chip useful in counterterrorism, water and food safety

    A new process for making a three-dimensional microstructure that can be used in the analysis of cells could prove useful in counterterrorism measures and in water and food safety concerns. Researchers developed a new microfabrication technique to develop three-dimensional microfluidic devices in polymers. Microfluidics deals with the performance, control, and treatment of fluids that are constrained in some fashion.
