• Smartphone turned into handheld biosensor

    Scientists and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses, and other molecules.

  • Oregon drills first responders for bioterrorism attack

    A three day drill called the Portland Area Capabilities Exercise (PACE), simulating a terrorist attack involving a biological weapon, will take place across fifty different facilities and sixty-five jurisdictions in the state of Oregon.

  • Ricin can kill, but there are more potent bioterror weapons

    Ricin was in the headlines a few weeks ago, when envelopes containing the poison were mailed to President Obama, Senator Roger Wicker (R-Mississippi), and a Mississippi judge. The threat from ricin is low, however, because ricin cannot poison someone through contact with the skin. To be poisoned, an individual would have to ingest or inhale traces of the poison.

  • New malaria test kit would help global elimination efforts

    A new, highly sensitive blood test that quickly detects even the lowest levels of malaria parasites in the body could make a dramatic difference in efforts to tackle the disease in the United Kingdom and across the world, according to new research.

  • Bird flu in live poultry markets source of viruses causing human infections

    Following analysis of H7N9 influenza viruses collected from live poultry markets in China, it was found that these viruses circulating among birds were responsible for human infections. These results provide a basis for the government to take actions for controlling this public health threat.

  • Studying botulinum genome to understand botulism harm

    The toxin that causes botulism is the most potent that we know of. Eating an amount of toxin just 1,000th the weight of a grain of salt can be fatal, which is why so much effort has been put into keeping Clostridium botulinum, which produces the toxin, out of our food.

  • Potential flu pandemic looms

    In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated one million people. A new study reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically similar to the 1968 strain and have the potential to generate a pandemic if they leap to humans.

  • Pennsylvania emergency professionals receive WMD training

    The Center for Domestic Preparedness (CDP) in Alabama hosted more than a hundred emergency professionals from the Pennsylvania South Central Mountains Regional Task Force’s Health and Medical Committee for in-depth response-to-WMD training.

  • Rendering mosquitoes immune to malaria parasites

    Scientists have established an inheritable bacterial infection in malaria-transmitting Anopheles mosquitoes that renders them immune to malaria parasites. The strategy holds promise for malaria control efforts.

  • Illnesses in U.S. on the rise as a result of decline in foreign food inspections

    More Americans get sick every year as a result of food-borne pathogens. The reason: inspections at foreign food factories shipping food and food ingredients to the United States have declined in recent years, and border inspections of food coming into the country could be next to be reduced. Experts say this decline in inspections is especially worrisome since Americans consume more imported food – or food made with imported ingredients – every year, and foreign food production and processing facilities often do not meet U.S. sanitation and hygiene standards.

  • Silica particles purify water by acting as oil magnets

    Engineers develop an innovative method designed to purify water through the rapid removal of oily pollutants. The technology involves the deployment of surface engineered silica particles, which act as oil magnets in water, adsorbing oil, yet repelling water.

  • Ebola's secret weapon revealed: its ability to short-circuit the immune system

    Researchers have discovered the mechanism behind one of the Ebola virus’ most dangerous attributes: its ability to disarm the adaptive immune system. Scientists determined that Ebola short-circuits the immune system using proteins that work together to shut down cellular signaling related to interferon. Disruption of this activity, the researchers found, allows Ebola to prevent the full development of dendritic cells that would otherwise trigger an immune response to the virus.

  • Schools do not offer students sufficient practical science experience

    New evidence shows that a worrying number of students are not experiencing a complete and authentic education in the sciences, due to a lack of resources for practical work. Secondary schools reported not having enough of some of the most commonly used equipment, such as microscopes, eye protection, and connecting leads for circuits. The research also shows that many secondary schools lack essential support from qualified technicians to carry out practical work.

  • Horse meat in the human diet

    Horse long has been on menus in continental Europe, sold from shops that often advertise with a carved horse head on the store front.A chemist explains the testing for horse DNA in food products, and discusses the concerns about selling and eating horse meat in the United States.

  • New fertilizer can be used to grow food – but not build bombs

    Ammonium nitrate fertilizer is used in agriculture, but when mixed with a fuel such as diesel, it is highly explosive. It was used in about 65 percent of the 16,300 homemade IEDs in Afghanistan in 2012.About 1,900 troops were killed or wounded in IED attacks in 2012, 60 percent of American combat casualties. There have been more than 17,000 global IED incidents in 123 countries in the past two years. Timothy McVeigh used ammonium nitrate in Oklahoma City in 1995. Scientists have developed a fertilizer that helps plants grow but cannot detonate a bomb.
