• Future of testing and treating chlorine gas attacks

    As experts sort through questions around recent chemical attacks in Syria, future answers to quickly testing and treating those who may have been exposed to chlorine gas may lie in chlorinated lipids, says a scientist.

  • “Mad camel” disease? New prion infection raises alarm

    Italian and Algerian researchers released new evidence of prion disease in three dromedary camels found in an Algerian slaughterhouse. Prion diseases can affect both humans and animals, and though inter-species transmission is rare, it can happen, as it did most famously during the bovine spongiform encephalopathy (BSE, or “mad cow”) epidemic, which started in the late 1980s in the United Kingdom.

  • U.S. health security preparedness improved, but some regions lagging

    A national snapshot used to gauge the health of the nation’s health security and emergency preparedness found that readiness has improved significantly over the past five years, but earlier identified gaps remain, with some parts of the country lagging.

  • The 100th meridian, where the Great Plains begin, shifting eastward

    In 1878, the American geologist and explorer John Wesley Powell drew an invisible line in the dirt—the 100th meridian west, the longitude he identified as the boundary between the humid eastern United States and the arid Western plains. Now, 140 years later, scientists that the line appears to be slowly moving eastward, due to climate change. They say it will almost certainly continue shifting in coming decades, expanding the arid climate of the western plains into what we think of as the Midwest. The implications for farming and other pursuits could be huge.

  • New technology removes phosphorus from manure

    Excess phosphorus, primarily in runoff from land application of manure, accounts for about 66 percent of impaired conditions of U.S. rivers and has created large areas of eutrophication — dead zones — in the Chesapeake Bay and the Gulf of Mexico, where aquatic life cannot survive. Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems. Researchers have developed an innovation that could have a huge impact on water quality problems in the United States, a system capable of removing almost all phosphorus from stored livestock manure.

  • Anti-immigrant prejudice linked to mortality risk

    One of the defining elements of the 2016 election cycle was its focus on immigration. One aspect of immigration did not figure in the discussion: When it comes to mortality, U.S.-born individuals of immigrant descent fare much worse than their foreign-born counterparts — but why?

  • Mimicking the human immune system to detect outbreaks faster

    Our immune systems are made up of billions of white blood cells searching for signs of infections and foreign invaders, ready to raise the alarm. Sandia National Laboratories computer scientists have been working to improve the U.S. biosurveillance system that alerts authorities to disease outbreaks by mimicking the human immune system.

  • A new class of antibiotics to fight drug resistance

    According to the World Health Organization, antibiotic resistant is one of the biggest threats to global health today and a significant contributor to longer hospital stays, higher medical costs and increased mortality. An international research team has reported the discovery of a new class of antibiotics.

  • CDC measures have limited spread of “nightmare” bacteria

    The Centers for Disease Control and Prevention (CDC) reported yesterday (3 April) that public health laboratories identified more than 220 samples of “nightmare” bacteria containing unusual resistance genes in 2017, a finding that officials say illustrates the importance of the agency’s efforts to identify emerging drug-resistant pathogens quickly and contain them before they can spread.

  • Climate change could increase food insecurity risk

    Weather extremes caused by climate change could raise the risk of food shortages in many countries, new research suggests. The study examined how climate change could affect the vulnerability of different countries to food insecurity – when people lack access to a sufficient quantity of affordable, nutritious food.

  • Funding restored to National Biodefense Analysis and Countermeasures lab

    The Fort Detrick, Maryland-based National Biodefense Analysis and Countermeasures Center (NBACC) is no longer facing an immediate jeopardy. The federal omnibus spending bill,  released last Wednesday evening, provided full funding for the biohazard laboratory – funding which the original administration’s budget proposal eliminated.

  • Better accountability needed of use of Ebola recovery funds: GAO

    A review of U.S.-funded Ebola recovery projects in Guinea, Liberia, and Sierra Leone by the U.S. Government Accountability Office (GAO) released this week found that, of $1.6 billion appropriated by Congress in 2014 for U.S. Agency for International Development (USAID) in the hard-hit region, $411.6 million has been targeted to 131 specific projects. However, in tallying up the projects and their scope, the GAO found that USAID needs to do more to ensure a complete inventory of all of its Ebola recovery projects.

  • Restoring subways in the event of a bioterrorist attack

    Only a week after the terrorist attacks of September 11, 2001, envelopes containing anthrax spores were sent to several media companies and two senators. As a result, twenty-two people were infected and five died. Since these incidents, the U.S. has increased its efforts on measures countering bioterrorism. That incident stemmed from spores sent to individuals and offices where the reach was somewhat contained. Imagine if the spores had been taken onto a mass transit platform — like the subway. A subway incident can bring a whole city to a halt, and the effects can last much longer in the form of lingering fear and mistrust.

  • Efficient extraction may improve management of nuclear fuel

    After used nuclear fuel is removed from a reactor, it emits heat for decades and remains radioactive for thousands of years. The used fuel is a mixture of major actinides (uranium, plutonium), fission products (mainly assorted metals, including lanthanides) and minor actinides (i.e., americium, curium and neptunium). After the cesium-137 and strontium-90 fission products decay in a few hundred years, the minor actinides and plutonium generate the most heat and radioactivity. Removal of the minor actinides, especially americium, can help nuclear power producers reduce and better manage the waste stream.

  • A synthesized antibiotic is capable of treating superbugs

    A “game changing” new antibiotic which is capable of killing superbugs has been successfully synthesized and used to treat an infection for the first time—and could lead to the first new class of antibiotic drug in thirty years. The breakthrough is another major step forward on the journey to develop a commercially viable drug version based on teixobactin—a natural antibiotic discovered by U.S. scientists in soil samples in 2015 which has been heralded as a “gamechanger” in the battle against antibiotic resistant pathogens such as MRSA and VRE.
