• SuperbugsPreventing a “post-antibiotic era”

    A landmark report by the World Health Organization in 2014 observed that antibiotic resistance — long thought to be a health threat of the future — had finally become a serious threat to public health around the world. A top WHO official called for an immediate and aggressive response to prevent what he called a “post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill.”

  • Water securityGenetic tool improves arsenic studies

    Arsenic-contaminated drinking water impacts millions of people worldwide. Groundwater contamination is primarily caused by microbes that convert one form of arsenic into another form that can infiltrate groundwater. Researchers developed a genetic tool that makes it easier to identify which microbial species have the arsenic-converting genes.

  • Travel banHow a travel ban could worsen doctor shortages in US hospitals and threaten primary care

    By John Burkhardt and Mahshid Abir

    While the world waits for a final decision on President Trump’s travel ban, potentially from the Supreme Court, it’s critical to look at the potential ramifications of the ban. As physicians involved with educating and training the next generation of doctors, we see dire consequences for health care delivery in our country if the travel ban is reinstated. President Trump’s immigration ban has the potential for immediate ramifications for the hospital and health care system workforce in the U.S. Long term, decreases in the number of international medical graduates in training will result in fewer primary care physicians and general surgeons, just as the country is likely to need more. This immigration policy can have significant adverse impacts on health care delivery and the health of Americans. These consequences should be critically considered in related immigration and travel ban policy decisions moving forward.

  • Radiation risksU.K. nuclear safety regulations place too low a value on human life

    New research has shown that the benchmark used by the U.K. Office for Nuclear Regulation for judging how much should be spent on nuclear safety has no basis in evidence and places insufficient value on human life. The review suggests it may need to be ten times higher — between £16 million and £22 million per life saved.

  • Emerging threatsWorld leaders urged to take action to avert existential global risks

    World leaders must do more to limit risk of global catastrophes, according to a report by Oxford academics. He academic define global catastrophe as a risk “where an adverse outcome would either annihilate Earth-originating intelligent life or permanently and drastically curtail its potential.” Three of the most pressing possible existential risks for humanity are pandemics, extreme climate change, and nuclear war.

  • SuperbugsStep closer to developing major new drug in fight against antimicrobial resistance

    Scientists have for the first time determined the molecular structure of a new antibiotic which could hold the key to tackling drug resistant bacteria. This development is an important next step in understanding how different derivatives of teixobactin function, and which building blocks are needed for it to successfully destroy drug resistant bacteria.

  • ISISISIS followers hack U.K. National Health Service

    ISIS-linked hackers have attacked and defaced several NHS (U.K. National Health Service) websites in a series of cyberattacks. The hackers, going by the name of Tunisian Fallaga Team, targeted six websites three weeks ago, replacing legitimate web pages with graphic photos of the war in Syria. The attacks said they were retaliating for the West’s interference in the Middle East.

  • Gas leaksLow-cost imaging system detects natural gas leaks in real time

    Researchers have developed an infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks in pipelines and at oil and gas facilities. Leaks of methane, the primary component of natural gas, can be costly and dangerous while also contributing to climate change as a greenhouse gas. Infrared device enables reliable monitoring under a range of environmental conditions.

  • SuperbugsMalaria superbugs pose threat to global malaria control

    A lineage of multidrug resistant P. falciparum malaria superbugs has widely spread and is now established in parts of Thailand, Laos and Cambodia, causing high treatment failure rates for the main falciparum malaria medicines, artemisinin combination therapies (ACTs). The emergence and spread of artemisinin drug resistant P falciparum lineage represents a serious threat to global malaria control and eradication efforts.

  • EpidemicsGlobal partnership to prevent epidemics with new vaccines launched

    A global coalition to create new vaccines for emerging infectious diseases, designed to help give the world an insurance policy against epidemics, launches today at the World Economic Forum in Davos, Switzerland.

    With an initial investment of $460 million from the governments of Germany, Japan, and Norway, plus the Bill & Melinda Gates Foundation and the Wellcome Trust, CEPI - the Coalition for Epidemic Preparedness Innovations will seek to outsmart epidemics by developing safe and effective vaccines against known infectious disease threats that could be deployed rapidly to contain outbreaks, before they become global health emergencies.

  • CholeraCocktail of bacteria-killing viruses prevents cholera infection in animal models

    Oral administration of viruses that specifically target cholera bacteria prevents infection and cholera-like symptoms in animal model experiments. The findings are the first to demonstrate the potential efficacy of bacteria-killing viruses—known as bacteriophages, or phages—as an orally administered preventive therapy against an acute gastrointestinal bacterial disease.

  • Water securityWhat caused the Flint water crisis

    Flint, Michigan, continues to grapple with the public health crisis that unfolded as lead levels in its tap water spiked to alarming levels. Now the scientists who helped uncover the crisis have tested galvanized iron pipes extracted from the “ground zero” house. They confirm that the lead that had accumulated on the interior surface of the pipes was the most likely source of the lead contamination.

  • Public healthNew material helps fight against hospital-acquired infections

    Researchers have developed a new light-activated antimicrobial material for use in the fight against the most common hospital infections. Specifically, the new material is a molybdenum complex that has never been used before in antimicrobial photodynamic therapy (PDT).

  • SuperbugsNevada woman killed by superbug resistant to every known antibiotic

    A 70-yer old woman in Nevada has died after a superbug which infected her proved resistant to every available type of antibiotic. The woman was already infected in India, where she had an extended stay, and was hospitalized there several times. She returned to Nevada in August 2016. She was admitted to a hospital shortly after her return, but died a month later after treatment with twenty-six different antibiotics was futile.

  • Emerging threatsNew framework needed for estimating the social cost of carbon: Report

    To estimate the social cost of carbon dioxide for use in regulatory impact analyses, the federal government should use a new framework that would strengthen the scientific basis, provide greater transparency, and improve characterization of the uncertainties of the estimates, says a new report by the National Academies of Sciences. The report also identifies a number of near- and longer-term improvements that should be made for calculating the social cost of carbon.
