• 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.

  • Stagnant U.S. funding for tools against infectious diseases leaves U.S., world at serious risk

    As Congress grapples with the White House on how to fund an emergency response to fight Zika virus, a new report warns that overall underfunding for development of lifesaving tools against neglected global diseases is putting the United States and the world at risk, and that emergency funding cannot be allowed to substitute for sustained U.S. investment in research and development (R&D) of global health technologies. A recent study that examined the risk of infectious disease outbreaks projected that large-scale global disease pandemics could cost the global economy more than $60 billion a year, while investing in the interventions needed to protect against these outbreaks, including R&D, would cost only a fraction of that — $4.5 billion — each year.

  • Congress’ inaction hobbles U.S. preparation for a major Zika virus outbreak: Experts

    Despite dire predictions that the Zika virus could affect much of the United States including large cities this summer, the country is unprepared, and the financial and moral consequences could be significant. Earlier this year, President Barack Obama requested $1.86 billion for surveillance, mosquito control, research and health services, but Congress has not approved the funding. In the absence of Congressional action, the president reallocated $589 million of designated Ebola funds to Zika preparedness, research and the creation of response teams. “The nation’s state of preparedness is compromised by Congress’s inaction on supplemental funding and the weak capacities and powers of states and localities,” two public health experts say.

  • New way to clean contaminated groundwater

    A team of researchers has helped discover a new chemical method to immobilize uranium in contaminated groundwater, which could lead to more precise and successful water remediation efforts at former nuclear sites. Uranium is present in contaminated groundwater at various sites in the United States as a legacy of Cold War-era processing and waste disposal activities associated with nuclear materials production.

  • Zika virus “scarier than we initially thought”: U.S. health officials

    Dr. Anne Schuchat from the Centre for Disease Control and Prevention (CDC) said the Zika virus is more of a threat than previously thought. Speaking at a White House press conference, she said there was potential for the virus to spread to more U.S. states than experts first believed. “Most of what we’ve learned is not reassuring. Everything we look at with this virus seems to be a bit scarier than we initially thought,” she told reporters.

  • Novel alignment-free sequence descriptors in Zika virus characterization

    The recent epidemic of Zika virus infections in South and Latin America has raised serious concerns on its ramifications for the population in the Americas and spread of the virus worldwide. Researchers explain their research on computer-assisted approaches toward surveillance and consequent design of drugs and vaccines to combat the growth and spread of the Zika virus.

  • Limited awareness or concern about Zika virus in U.S.

    A recent survey by the Associated Press-NORC Center for Public Affairs Research finds that three-quarters of Americans who have heard at least a little about the Zika virus are aware that the virus is linked to birth defects in babies born to infected mothers. However, the survey found that most Americans are unclear about the availability of tests to diagnose Zika and whether or not preventative vaccines and effective medicines exist to treat it.

  • Oil, gas wastewater disposal pollutes surface water, harm waterways

    Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas and oil from underground rock. This process results in in water pollution which may increase endocrine disrupting chemicals (EDCs) in surface and ground water, exposing populations living near these operations to increased risk of disease. High levels of EDC activity were found in the surface water near a hydraulic fracturing wastewater disposal facility in West Virginia. Approximately 36,000 of these disposal wells are currently in operation across the United States.

  • Paper-based test to help prevent food poisoning

    The foodborne bacteria Salmonella alone led to nearly 20,000 hospitalizations and almost 400 deaths in 2013. Economists estimate that the treatment of all these patients and the related productivity losses cost more than $3 billion annually. And those numbers account for just one of the fifteen pathogens responsible for most of the food poisoning cases. Scientists have developed a simple, paper-based test that could help detect pathogens hitchhiking on food before they reach store shelves, restaurants and, most importantly, our stomachs.

  • 2010 Maryland food poisoning outbreak traced to Asian strain of seafood pathogen

    V. parahaemolyticusis the most important cause of seafood poisoning in the United States. Approximately 4,500 cases occur annually in the United States, according to the Center for Disease Control and Prevention. The number of cases has risen in recent years, possibly do to the warming climate.

  • Protecting soldiers from emerging infectious diseases

    Emerging infectious diseases that the U.S. military could encounter around the globe, particularly those found in tropical settings such as dengue, Burkholderia melioidosis, and malaria, are often difficult to distinguish by their clinical characteristics alone. Scientists from the Naval Health Research Center (NHRC) and the Defense Threat Reduction Agency (DTRA) held a two-day meeting earlier this month to discuss progress and goals for a joint biosurveillance project which aims to develop novel point of need (PON) diagnostics to identify pathogens that cause acute febrile illnesses and threaten global and public health.

  • Expanding use of recycled water would benefit the environment, human health

    More than 1 in 9 people around the world, about 750 million, do not have access to safe, clean drinking water, and the problem is expected to worsen in step with rising greenhouse gas concentrations, population increases and climate change. Researchers found that found that recycled water has great potential for more efficient use in urban settings and to improve the overall resiliency of the water supply.

  • Better tracking of police homicides

    Official counts of homicides by police seriously undercount incidents, according to a study, but a relatively new national data system, currently in use in thirty-two states, could be a crucial tool for gathering more comprehensive information, say the researchers.

  • Conditions increasing Zika virus risk present in many U.S. cities

    Key factors that can combine to produce a Zika virus outbreak are expected to be present in a number of U.S. cities during peak summer months. The Aedes aegypti mosquito, which is spreading the virus in much of Latin America and the Caribbean, will likely be increasingly abundant across much of the southern and eastern United States as the weather warms, according to a new study.
