• World public health authorities alarmed about a new coronavirus related to viruses from bats

    The virus which is causing alarm among global public health authorities after it killed a man in Jeddah, Saudi Arabia earlier this year and is now linked to two other cases of disease, is a novel type of coronavirus most closely related to viruses found in bats, according to a genetic analysis

  • The challenge of securing food and water supplies in the twenty-first century

    Participants in the Food Security in Dry Lands (FSDL) conference, held last week in Qatar, agreed that the task of managing food and water resources more efficiently and improving the security of supply are set to become one of the biggest challenges for policy makers in the twenty-first century

  • Protecting U.S. troops against sand flies

    Sand flies are vectors of Leishmania parasites that cause leishmaniasis, a devastating disease for which there is no vaccine or medication; people who are bitten by infected sand flies do not know whether they have the disease until it becomes apparent three or four months later; U.S. Department of Agriculture (USDA) scientists are helping deployed American troops protect themselves against sand flies, which are major pests in Afghanistan, Africa, and the Middle East

  • Biosecurity paramount to ensure Australia retrains healthy agricultural output

    Experts at the State Biosecurity Forum, held ten days ago in Australia, recommend strong partnerships and global strategies to secure protection of present and future agriculture for Western Australia (WA); the participants at the event discussed issues ranging from the effects of climate change and UV radiation on biosecurity to the implementation of computer modeling in agricultural policy making decisions

  • Scanning social media as a tool for biosurveillance

    DHS is considering observing and scanning social media Web sites to collect and analyze health-related data which could help identify outbreaks of infectious diseases and other public health and national security risks

  • Baiting mosquitoes with knowledge and proven insecticides

    While one team of U.S. Department of Agriculture (USDA) scientists is testing the effectiveness of pesticides against mosquitoes, another group is learning how repellents work; scientists are evaluating insecticides and designing innovative technology to fight biting insects and arthropods

  • The Coca-Cola model for delivering malaria meds is a success, should be continued

    A controversial program that uses the private market to provide affordable malaria treatments to people in Africa has dramatically increased access to care and should be continued; The private-market approach — sometimes called the Coca-Cola model in reference to the soda’s apparent ability to reach remote areas of the world — aims to deliver drugs in regions where the majority of people obtain medicines from shops rather than from district hospitals or clinics

  • Scientists: some diseases designated as “emerging” have been around for centuries

    The Ebola, Marburg, and Lassa viruses are commonly referred to as emerging diseases, but leading scientists say these life-threatening viruses have been around for centuries; researchers say it would be more appropriate to refer to these viruses as emerging diagnoses

  • Global monitoring of infectious diseases in dogs and cats to protect humans

    Most emerging infectious diseases of humans come from animals. International health agencies monitor these diseases, but they do so only for humans and livestock, not for companion dogs and cats; a new study recommends a global system is needed to monitor infectious diseases of companion dogs and cats

  • Cleanup of most contaminated U.S. groundwater sites unlikely for many decades

    At least 126,000 sites across the United States have contaminated groundwater that requires remediation, and about 10 percent of these sites are considered “complex,” meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations; the estimated cost of complete cleanup at these sites ranges from $110 billion to $127 billion, but the figures for both the number of sites and costs are likely underestimates

  • Intensive farming with a climate-friendly touch

    In the world of agriculture, climate protection and intensive farming are generally assumed to be a contradiction in terms; scientists have come up with a new land development concept that could change this view; the new model is tailored to medium-sized farms in South America and sees farmers transitioning from large-scale monoculture to more diverse crop mixtures spread over smaller plots interspersed with wooded areas — a switch that can bring significant financial benefits

  • Indian monsoon failure more frequent with warming

    Global warming could cause frequent and severe failures of the Indian summer monsoon in the next two centuries, new research suggests; the effects of these unprecedented changes would be extremely detrimental to India’s economy which relies heavily on the monsoon season to bring fresh water to the farmlands

  • USGS sampling water in Hurricane Sandy’s aftermath to ensure public health

    Excessive nutrients in U.S. rivers, streams, and coastal areas are a major issue for water managers, because they cause algal blooms that increase costs to treat drinking water, limit recreational activities, and threaten valuable commercial and recreational fisheries; U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane

  • A coal economy has multiple health, social risks, says major review

    A major review of evidence on the impact of coal mining has highlighted serious, ongoing health and social problems, and an urgent need for improvements in government coal mining policy

  • Technology used in BioWatch could not detect pathogens, issued false alarms

    The BioWatch program was created to detect the release of pathogens in the air as part of a terrorist attack, but scientists say that the program is unable to detect lethal germs because the system uses defective components; these components often set off false alarms; for example, BioWatch sensors issued fifty alarms between 2003 and 2008, but scientists and security authorities never had enough confidence in the BioWatch system to evacuate an area or take other emergency steps
