• A new paper-based test for the Zika virus

    A new paper-based test developed at MIT and other institutions can diagnose Zika virus infection within a few hours. The test, which distinguishes Zika from the very similar dengue virus, can be stored at room temperature and read with a simple electronic reader, making it potentially practical for widespread use.

  • Israeli tech ready to take on Zika-carrying mosquito

    The mosquito-borne Zika virus, according to new reports, is even more dangerous than first believed. While better information about prevention has helped slow the rate of infection in some areas, the health community is still urgently searching for a vaccine or drug treatment. The world seeks a medical intervention, but Biofeed’s no-spray green product targets the insects directly.

  • Developing new anthrax vaccine

    The Texas A&M Center for Innovation in Advanced Development and Manufacturing (CIADM) will produce an intranasal anthrax vaccine candidate under a task order issued by the U.S. Department of Health and Human Services (HHS). This is the first task order issued to the Texas A&M center and will enhance protection from anthrax disease. The Texas A&M facility is one of three CIADMs — and the only academically-based center — established as public-private partnerships with BARDA in 2012 to enhance the nation’s emergency preparedness against emerging infectious diseases.

  • The long history of lead poisoning in the U.S.

    While state and federal officials continue to criticize each other for failing to guarantee safe drinking water, the question of exactly who is responsible for crises like in Flint, Michigan, lies at the root of the problem. “The crisis in Flint brought the true costs of a neglected infrastructure to the nation’s attention, but in the finger-pointing there are deeper debates over public and private responsibility and the impact of dysfunctional politics on public health,” says one expert.

  • Floods, coastal erosion may expose contents of UK landfills

    The contents of historic coastal landfill sites in England and Wales could pose a significant environmental threat if they erode, according to a new study. The main risks to these landfills come from the effects of climate change, including erosion and flooding with salt water from storm surges and higher water levels.

  • Measuring electromagnetic radiation exposure

    Society demands continuous implementation of new transmission systems due to ongoing development of communication technologies. These systems work by emitting electromagnetic waves. As a result, population is exposed to a significant increase of environmental radiation levels. Researchers from UPM have developed a portable device that allows continuous monitoring the exposure levels to electromagnetic radiations of a person who wears such device.

  • New drug to combat the effects of nerve agents

    Sarin is a colorless, odorless liquid fatal even at very low concentrations. Serious sarin poisoning causes visual disturbance, vomiting, breathing difficulties and, finally, death. A ground-breaking study describes the development of a new drug which counteracts the effects of sarin gas.

  • More corrosion-resistant water pipes could preventing another Flint, Mich. health crisis

    Corrosion-related damage costs more than three percent of the United States’ Gross Domestic Product (about $503.1 billion, going by 2013 numbers). With documented public water problems in Flint, Michigan, and Hoosick Falls, New York, caused by corrosion, understanding how copper is affected at the atomic level is critical to avoiding problems in future pipes.

  • Illegal mining in Colombia linked to malaria outbreak

    The Colombian National Health Institute recorded 18,524 malaria cases in 2015. The year before, only 4,730 malaria cases were recorded. The sharp increase in the number of malaria cases in different areas of Colombia has been linked to illegal open-cast mining. Stagnant water and poor sanitary conditions have been discovered at these often hidden rural locations.

  • Cellphone-sized device detects the Ebola virus quickly

    The worst of the recent Ebola epidemic is over, but the threat of future outbreaks lingers. Monitoring the virus requires laboratories with trained personnel, which limits how rapidly tests can be done. Now scientists report in ACS’ journal Analytical Chemistry a handheld instrument that detects Ebola quickly and could be used in remote locations.

  • What we learned from Chernobyl about how radiation affects our bodies

    The world has never seen a nuclear accident as severe as the one that unfolded when a reactor exploded in Chernobyl on 26 April 1986, sending vast amounts of radiation into the skies around Ukraine, Belarus and Russia. The planet had experienced massive releases like this before, in the bombings of Hiroshima and Nagasaki in 1945. But Chernobyl-related radiation exposure had a more protracted character. It was the first time in history that such a large population, particularly at a very young age, was exposed to radioactive isotopes, namely iodine-131 and cesium-137, not just through direct exposure, but through eating contaminated food as well.

  • The legacy of Chernobyl -- 30 years on

    The 26 April 2016 marks the 30th anniversary of the Chernobyl nuclear accident. For many, especially those born since 1986, it is a word they know without appreciating the full significance of what happened on that day. For others, it was a life changing catastrophe which resulted in largest release of radioactivity in the history of nuclear energy.

  • Dealing with irradiated nuclear graphite

    Since the beginning of the nuclear power industry, a large number of channel uranium-graphite nuclear power reactors was built across the world. To date, they all are on the output stage of the operation or decommissioning preparation. Approximately 250,000 tons of irradiated graphite are accumulated in the world, including ~ 60,000 tons in Russia. Due to the specificity of irradiated graphite, the treatment of this type of radioactive waste has not been determined yet.

  • Forget Fukushima: Chernobyl still holds record as worst nuclear accident for public health

    The 1986 Chernobyl and 2011 Fukushima nuclear power plant accidents both share the notorious distinction of attaining the highest accident rating on the International Atomic Energy Agency (IAEA) scale of nuclear accidents. No other reactor incident has ever received this Level 7 “major accident” designation in the history of nuclear power. But the IAEA scale isn’t designed to measure public health impact. Chernobyl is by far the worst nuclear power plant accident of all time. It was a totally human-made event which was made worse by incompetent workers who did all the wrong things when attempting to avert a meltdown. Fukushima in contrast, was an unfortunate natural disaster – caused by a tsunami that flooded reactor basements — and the workers acted responsibly to mitigate the damage despite loss of electrical power. In terms of health ramifications, these two nuclear accidents were not even in the same league. While Fukushima involved radioactivity exposures to hundreds of thousands of people, Chernobyl exposed hundreds of millions. And millions of those received substantially more exposure than the people of Fukushima.

  • Changing climate in Michigan poses an emerging public health threat

    Changing climate conditions — including warmer temperatures and an increased frequency of heavy rainstorms — represent “an emerging threat to public health in Michigan,” according to a new report from University of Michigan researchers and state health officials.
