• “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.

  • 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.

  • 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.

  • Too many hospitalized kids receive preventive antibiotics

    A large new international study indicates that nearly a third of hospitalized children are receiving antibiotics to prevent bacterial infections rather than to treat them, and in many cases are receiving broad-spectrum antibiotics or combinations of antibiotics. This high rate of prophylactic prescribing in pediatric patients and frequent use of broad-spectrum agents suggests a clear overuse of antibiotics in this population and underscores the need for pediatric-specific antibiotic stewardship programs.

  • Sandia transport triathlon puts spent nuclear fuel to the test

    Nuclear power supplies almost 20 percent of U.S. electricity and is the leading carbon-neutral power source. However, it produces between 2,200 and 2,600 tons of spent fuel in the United States each year. Fuel rods become brittle and highly radioactive while powering the nuclear reactor, making safe transportation important. Sandia National Laboratories researchers completed an eight-month, 14,500-mile triathlon-like test to gather data on the bumps and jolts spent nuclear fuel experiences during transportation.

  • Pipe-crawling robot to help decommission DOE nuclear facility

    A pair of autonomous robots developed by Carnegie Mellon University’s Robotics Institute will soon be driving through miles of pipes at the U.S. Department of Energy’s former uranium enrichment plant in Piketon, Ohio, to identify uranium deposits on pipe walls. The CMU robot has demonstrated it can measure radiation levels more accurately from inside the pipe than is possible with external techniques.

  • Climate change to fuel more extreme heat waves in western U.S. by 2020

    Human-caused climate change will drive more extreme summer heat waves in the western United States, including in California and the Southwest as early as 2020, new research shows. Understanding the driving forces behind the projected increase in occurrence and severity of heat waves is crucial for public health security and necessary for communities to develop extreme heat mitigation strategies, said the authors.

  • Identifying the key drivers of high U.S. healthcare spending

    The major drivers of high healthcare costs in the U.S. appear to be higher prices for nearly everything—from physician and hospital services to diagnostic tests to pharmaceuticals—and administrative complexity. The study confirmed that the U.S. has substantially higher spending, worse population health outcomes, and worse access to care than other wealthy countries.

  • Nerve agents: what are they and how do they work?

    The first nerve agents were invented by accident in the 1930s when researchers were trying to make cheaper and better alternatives to nicotine as insecticides. In their search, German scientists made two organic compounds containing phosphorus that were very effective at killing insect pests. However, they soon discovered that, even in minuscule amounts, the substances caused distressing symptoms in humans exposed to them. The two substances – too toxic to be used as commercial insecticides in agriculture – became known as tabun and sarin. Since then, other nerve agents have been developed, but much less is known about them, although they are thought to work in broadly the same way. Unlike street drugs, nerve agents cannot be made in your kitchen or garden shed, on account of their toxicity, even in tiny amounts. Synthesis of nerve agents requires a specialist laboratory, with fume cupboards. As more details emerge from the case of former Russian spy Sergei Skripal, we’ll know more about the precise substance used and how it should be tackled. Either way, nerve agents are horrendously lethal and chemical warfare is an obscene use of chemicals.

  • Low-cost arsenic sensor could save lives

    Worldwide, 140 million people drink water containing unsafe levels of arsenic, according to the World Health Organization. Short-term exposure causes skin lesions, skin cancer and damage to the cognitive development of children, while long-term exposure leads to fatal internal cancers. A new low-cost, easy-to-use sensor which can test drinking water for arsenic in just one minute.
