• Real-time livestock disease situational awareness

    Veterinarians are the U.A. first responders for animal health, acting as the primary line of defense against animal disease outbreaks and are essential to the protection of our animal industries and economy. Researchers at the National Center for Foreign Animal and Zoonotic Disease Defense (FAZD Center) are working with veterinarians, federal and state animal health officials, and industry partners to improve real-time situational awareness of animal diseases.

  • Security of dirty bomb materials in U.S. inadequate: experts

    There are more than 5,000 medical and research devices in the United States containing high-activity radiation sources, including 700 with category-1 sources. Category-1 radiation material could be used by terrorists in dirty bombs. The security measures developed by the industry were written with accident prevention in mind, not in order to thwart a deliberate, forcible effort by terrorists or criminals to gain control of the toxic material. In addition, radioactive materials were considered to be “self-protecting,” because it was assumed that the powerful radiation would deter anyone thinking of tampering with these devices. Terrorist bomb-makers, however, showed themselves to be more technologically-savvy than earlier thought, and, in any event, suicide bombers would not be deterred by the risk of radiation poisoning.

  • HHS to fund development of drug for bioterrorism, antimicrobial-resistant infections

    HHS says that a public-private is partnership will advance the development of Carbavance, a new option to treat bioterrorism threats and antibiotic-resistant infections. The two bioterrorism Carbavance will address are melioidosis, also known as Whitmore’s disease, and glanders. Both melioidosis and glanders can become resistant to existing antibiotics. Already, with existing antibiotic treatments, approximately 40 percent of people who become ill from these bacteria die from the illness, and up to 90 percent die if not treated.

  • Children living near overhead power lines do not have greater risk of leukemia

    Children who live near overhead power lines in early life do not have a greater risk of developing childhood leukemia, researchers find. The study included nearly 16,500 children who were diagnosed with leukemia in Britain between 1962 and 2008. An earlier study using information on childhood leukemia diagnosed between 1962 and 1995 had suggested that there was an elevated risk for children born within 600 meters of overhead power lines. This new study includes children diagnosed up until 2008, and finds that children born after the 1980s do not have an increased risk.

  • NSF rapid response research grants to fund study of West Virginia chemical spill

    On 9 January 2014, crude 4-methylcyclohexane methanol (MCHM), a chemical primarily used to clean coal, leaked from a storage tank near Charleston, West Virginia, and bled into a river upstream of a water-treatment plant. As a result, about 15 percent of the state’s residents were advised not to drink the water. Better to understand the properties of the chemical that contaminated the drinking water, and the plumbing and water-treatment systems surrounding the area, the National Science Foundation (NSF) has awarded Rapid Response Research (RAPID) grants to research teams at three universities. These grants also will provide STEM learning opportunities for undergraduate and graduate students on the research teams.

  • Growing body of evidence connects lead’s deleterious effects to criminal behavior

    Violent crimes had reached an all-time high in the United States in the early 1990s, but by the end of the decade, the homicide rate had plummeted by more than 40 percent. Many theories were offered to explain this dramatic decline, but a new explanation is gaining credence: the banning of lead from gasoline and paint in the early 1970s. Babies born post-ban were exposed to far less lead – with its proven contribution to lowering IQ and causing attention problems and antisocial tendencies — and twenty years on, these babies became young adults who committed fewer crimes than their predecessors.

  • Oregon man infected with the plague leaves ICU

    Paul Gaylord, a welder from Prineville in rural Oregon, who in July 2012 contracted bubonic plague from a stray cat, has recovered and can now reflect on his experience. After admission to the hospital, Gaylord lapsed into a coma for twenty-seven days. While in a coma, his hands and legs swelled and turned black. The doctors told him that tests showed he was infected with the bubonic plague, and that his fingers would have to be amputated.

  • Senegal climate change-induced flooding reaching crisis proportions: UN

    Margareta Wahlstrom, the head of the UN disaster risk, last week warned that climate change-induced flooding had reached crisis proportions in Senegal, with some towns and villages now finding themselves underwater for large parts of the year. Wahlstrom, who was in Senegal for a 3-day visit as part of the UN preparations for a new global disaster risk-reduction strategy, said that mayors of coastal and riverside towns and villages told her their streets were flooded ten months out of twelve.

  • Chemical, physical traits of post-nuclear detonation fallout identified

    Post-detonation nuclear forensics relies on advanced analytical techniques and an understanding of the physio-chemical processes associated with a nuclear detonation to identify the device type and the source of the nuclear material in the device. Researchers have begun to develop a technique that provides a practical approach for looking into the complex physical and chemical processes that occur during fallout formation following a nuclear detonation.

  • Antibiotic “smart bomb” targets specific strains of bacteria

    Researchers have developed a de facto antibiotic “smart bomb” that can identify specific strains of bacteria and sever their DNA, eliminating the infection. The technique offers a potential approach to treat infections by multi-drug resistant bacteria.

  • The 9 January chemical leak in West Virginia is the latest in a long history of industrial accidents

    The chemical spill that affected the water source in nine West Virginia counties in early January is part of a long history of industrial accidents resulting from the concentration of chemical and coal-mining operations in the region. The 9 January spill, which saw coal-cleansing chemical which leaked from Freedom Industries’ storage tank into the Elk River, leaving more than 300,000 residents without access to clean tap water for days, is the latest in a history of pollution which has poisoned groundwater, spewed toxic gas emissions, and caused fires and explosions.

  • Federal, state chemical safety agencies increasingly hampered by budget cuts

    The budgets of state and federal agencies tasked with responding to the Elk River chemical spill have recently been cut, and these cuts have limited these agencies’ ability to prevent or respond to disasters such as the water crisis in West Virginia. “We do less,” said a CDC financial official, when asked the results of cuts. “What [the CDC director] has often been quoted as saying is that threats are not going down and so it is concerning to not be able to grow with the public health threats.”

  • Faster way to spot bacteria-tainted food -- and prevent illness

    The regular appearance of food poisoning in the news, including a recent event that led to the recall of more than 33,000 pounds of chicken, drives home the need for better bacterial detection long before meats and produce make it to the dinner table.

  • Cause of one of the most devastating pandemics in human history found

    An international team of scientists has discovered that two of the world’s most devastating plagues — the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe — were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s. These findings suggest a new strain of plague could emerge again in humans in the future.

  • New strategy for controlling epidemics in big cities

    Influenza places a huge burden upon society, both physically and economically. It is estimated that influenza costs the United States economy over $87 billion annually. In a large city like Washington, D.C., with about 50,000 visitors on any given day who stay for just a few days, there is a constant influx of new people who are susceptible to infections. Further, they visit highly populated tourist destinations, where they come into contact with other visitors as well as residents. Researchers, for the first time, model in detail how transient populations impact the spread of an illness, and how outbreaks such as influenza can be curbed by encouraging healthy behaviors in high-traffic tourist destinations.
