• Weather reports aid life-or-death decisions in Africa

    The people living in sub-Saharan Africa have a life-or-death dependency on information about the weather. Knowing when, where, and what to grow or graze animals can be the difference between a bumper harvest and facing starvation. Although sub-Saharan Africa depends more directly on rainfall than any other region on Earth, the region has the fewest number of rain monitoring stations. There are also significant delays in the time between measurements being made and the resulting data being made available.

  • Dangerous strains of E. coli may linger longer in water

    A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds. The research may help explain why water quality tests do not always accurately capture water-related health risks.

  • Fast, reliable identification of pathogens

    Life-threatening bacterial infections cause tens of thousands of deaths every year in North America, but current methods of culturing bacteria in the lab can take days to report the specific source of the infection, and even longer to pinpoint the right antibiotic that will clear the infection. Researchers have created an electronic chip that can analyze blood and other clinical samples for infectious bacteria with record-breaking speed.

  • Responding to public health emergencies

    Over the past decade, community engagement has become a central tenet of U.S. federal approach to public health emergency preparedness. Little is known, however, about how the vision of a ready, aware, and involved populace has translated into local practice.

  • Studying the deadly secrets of flu, Ebola, West Nile viruses

    In an effort to sort out why some viruses such as influenza, Ebola, and West Nile are so lethal, a team of U.S. researchers plans a comprehensive effort to model how humans respond to these viral pathogens. The goal of the study will be to provide a detailed molecular understanding of what occurs when these viruses infect their hosts, providing a foundation for the design and development of a new generation of drugs to thwart infection by some of the world’s most serious pathogens.

  • Fukushima-derived radioactivity in seafood poses minimal health risks

    Researchers find that the likely doses of radioactivity ingested by humans consuming fish contaminated by radioactive radiation escaping from the debilitated Fukushima reactors fish, are comparable to, or less than, the radiological dosages associated with other commonly consumed foods, many medical treatments, air travel, and other background sources.

  • Six out of ten people on Earth still lack access to flush toilets, adequate sanitation

    It may be the twenty-first century, with all its technological marvels, but six out of every ten people on Earth still do not have access to flush toilets or other adequate sanitation — measures that protect the user and the surrounding community from harmful health effects — according to a new study.

  • Faster method to identify Salmonella strains

    There are more than a million estimated cases of salmonellosis annually in the United States, resulting in approximately 400 deaths, nearly 20,000 hospitalizations and an economic burden of millions of dollars. New method may significantly reduce the time it takes health officials to identify Salmonella strains.

  • U.S. unlikely to meet its biofuel goals

    The Energy Independence and Security Act of 2007 (EISA) mandates that by 2022 the United States derive fifteen billion gallons per year of ethanol from corn to blend with conventional motor fuels. A new study says that if the climate continues to evolve as predicted by the Intergovernmental Panel on Climate Change, the United States stands little to no chance of satisfying its biofuel goals.

  • Health impact of Chernobyl accident overestimated: study

    The impact of the Chernobyl nuclear accident has been seriously overestimated, while unfounded statements presented as scientific facts have been used to strangle the nuclear industry, according to Russian researchers.

  • Current methods of reducing arsenic contamination of water are not effective

    Arsenic is now recognized to be one of the world’s greatest environmental hazards, threatening the lives of several hundred million people. Naturally occurring arsenic leaches into water from surrounding rocks and once in the water supply it is both toxic and carcinogenic to anyone drinking it. New research finds that most of the current technologies used around the world to reduce arsenic contamination are ineffective.

  • Letters containing ricin sent to Mayor Michael Bloomberg, gun-control advocacy group

    Two letters sent to Mayor Michael Bloomberg – one to his office in New York, the second to the Washington, D.C. offices of Mayors Against Illegal Guns, a non-profit gun-control group he has founded — contained traces of the deadly poison ricin.

  • Spokane, Wash. biolab could be closed due to budget cuts

    Just two weeks ago, law enforcement agencies credited a bioterrorism laboratory in Spokane, Washington with quickly identifying the substance in several letters mailed to people in town as ricin. These same agencies now say that the biolab could close as a result of budget cuts.

  • Improving “crop per drop” boosts global food security, water sustainability

    New study shows increasing crop water productivity could feed an additional 110 million people while meeting the domestic water demands of nearly 1.4 billion.

  • A majority on Earth will soon face severe, self-inflicted water shortage: scientists

    A conference of 500 leading water scientists from around the world, held last week in Bonn, issued a stark warning that, without major reforms, “in the short span of one or two generations, the majority of the nine billion people on Earth will be living under the handicap of severe pressure on fresh water, an absolutely essential natural resource for which there is no substitute. This handicap will be self-inflicted and is, we believe, entirely avoidable.”
