• 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Office implementing Obamacare avoids furloughs

    Gary Cohen, the director of the Center for Consumer Information and Insurance Oversight, said Wednesday that his office will not be furloughing its workers due to the federal budget cuts known as the sequester. His office is in charge of implementing most of President Obama’s healthcare law.

  • Preventing bugs from becoming antibiotic-resistant

    About 440 000 new cases of drug-resistant tuberculosis emerge annually, causing around 150 000 deaths. New research finds that bacteria can evolve resistance more quickly when stronger antibiotics are used. The rate of evolution of antibiotic resistance speeds up when potent treatments are given because resistant bacterial cells flourish most during the most aggressive therapies.

  • Fighting superbugs with a new genre of antibodies

    In an advance toward coping with bacteria that shrug off existing antibiotics and sterilization methods, scientists are reporting development of a new family of selective antimicrobial agents that do not rely on traditional antibiotics.

  • U.S. hospitals shipping sick immigrants back to their home countries

    Hundreds of immigrants who are in the United States illegally end up in the hospital only to find out they will be sent home through a removal system run by hospitals trying to avoid the high cost of treating illegal immigrants.

  • Bird flu mutation study offers vaccine clue

    Scientists have described small genetic changes that enable the H5N1 bird flu virus to replicate more easily in the noses of mammals. So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus cannot replicate efficiently in the nose.
