• The Invisible Threat

    In 1995, during the Monday morning rush hour in the Tokyo subway, thousands of commuters inhaled toxic nerve gas left leaking from little plastic bags. Twelve people died, and thousands more were injured in the deadliest attack in Japan since the Second World War. The attack was the work of Japanese cult Aum Shinrikyo. The cult members, many of them students of science, were unsuccessful in launching a true biological attack. They were clumsy and unfocused and the tools too complex to pull off with ease. But those efforts were in the mid-1990s, and the tools for creating bioattacks have become more accessible. The Trump administration, however, is threatening to cut the funding for science needed to defend against such attacks.

  • Flesh-eating parasites come closer, but a vaccine against them does, too

    Parasites that ulcerate the skin, can disfigure the face, and can fatally mutilate internal organs are creeping closer to the southern edges of the United States. No vaccine is yet available against Leishmania — the second-deadliest parasites in the world, topped only by malaria — but researchers have now come closer to changing that. A new experimental vaccine has immunized laboratory mice that were genetically altered to mimic the human immune system. The vaccine exploits a weakness in Leishmania’s tricky chemical camouflage, which normally hides it from the victim’s disease-fighting cells, to trigger a forceful immune response against the parasite.

  • Nose spray treatment for cyanide poisoning

    The first nose spray treatment for the life-threatening effects of cyanide poisoning will be developed under an agreement between HHS and Response and Emergent BioSolutions of Gaithersburg, Maryland. The treatment is needed because cyanide could be used as a chemical weapon against the United States, according to the agency.

  • Cleaning up subways after release of biological warfare agent such as anthrax

    If you’re like most people, you don’t spend much time thinking about what would happen if anthrax was released into your local subway system. But Sandia Lab engineer Mark Tucker has spent much of the past twenty years thinking about incidents involving chemical or biological warfare agents, and the best ways to clean them up. Tucker’s current project focuses on cleaning up a subway system after the release of a biological warfare agent such as anthrax.

  • Lax policies governing dual-use research, scientists unaware of research’s biosecurity implications

    The National Academies of Sciences has examined policies and practices governing dual-use research in the life sciences – research that could potentially be misused to cause harm – and its findings identify multiple shortcomings. While the United States has a solid record in conducting biological research safely, the policies and regulations governing the dissemination of life sciences information that may pose biosecurity concerns are fragmented. Evidence also suggests that most life scientists have little awareness of biosecurity issues, the report says, stressing the importance of ongoing training for scientists.

  • Map shows how to disable dangerous bioweapon

    The Centers of Disease Control (CDC) ranks tularemia as one of the six most concerning bioterrorism agents, alongside anthrax, botulism, plague, smallpox and viral hemorrhagic fever. And Russian stockpiles of it likely remain. American scientists studying F. tularensis recently mapped out the complex molecular circuitry that enables the bacterium to become virulent. The map reveals a unique characteristic of the bacteria that could become the target of future drug development.

  • World unprepared to deal with the effects of a thermonuclear attack

    The world is not prepared to deal with the devastating effects of a thermonuclear attack, says an University of Georgia’s Cham Dallas. He said that the development of a hydrogen bomb by North Korea is a transformative event, especially from the point of view of the medical and public health response to a thermonuclear detonation.

  • Water supply, quality in U.S. West affected by increased wildfire-caused erosion

    A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs. The area burned annually by wildfires has increased in recent decades and is expected to continue to increase this century. Many growing cities and towns rely on water from rivers and reservoirs that originates in watersheds where wildfire and sedimentation are projected to increase. Increased sedimentation could negatively impact water supply and quality for some communities.

  • New biosecurity initiative to advance benefits, reduce risks of life sciences research

    A new biosecurity initiative at Stanford’s Freeman Spogli Institute for International Studies (FSI) aims to identify and mitigate biological risks, both natural and man-made, and safeguard the future of the life sciences and associated technologies. The biosecurity initiative will seek to advance the beneficial applications of the life sciences while reducing the risks of misuse by promoting research, education and policy outreach in biological security.

  • Hospitalization costs of gun injuries exceeds $622 million a year

    Hospitalization costs associated with gun injuries in the United States exceeded $622 million a year, according to a new study. 57 percent of all firearm hospitalization costs were either paid by Medicaid—at more than $205 million—or not paid at all, as uninsured victims accounted for $155 million of the costs. More than 80 percent of firearm injury hospitalizations were among individuals age 15 to 44, with the highest annual rate of 28.9 per 100,000 among those age 15 to 24.

     

  • Radiation analysis software from Sandia Lab helps emergency responders

    When law enforcement officers and first responders arrive at an emergency involving radiation, they need a way to swiftly assess the situation to keep the public and environment safe. Having analysis tools that can quickly and reliably make sense of radiation data is of the essence. Sandia National Laboratories developed a tool called InterSpec, available for both mobile and traditional computing devices, can rapidly and accurately analyze gamma radiation data collected at the scene.

  • Biosecurity and synthetic biology: it is time to get serious

    Synthetic biology has only been recently recognized as a mature subject in the context of biological risk assessment — and the core focus has been infectious diseases. In the case of biosecurity, we’re already dependent on biology [with respect to food, health etc.] but we still have an opportunity to develop biosecurity strategies before synthetic biology is ubiquitous. There is still an opportunity to act now and put norms and practices in place because the community is still relatively small. “If scientists are not taking care of biosecurity now, other people will start taking care of it, and they most likely will start preventing researchers from doing good science.”

  • Flooding from Hurricane Harvey causes a host of public health concerns

    Houston’s drinking water system is being stressed by overflowing water reservoirs and dams, breached levees and possible problems at treatment plants and in the water distribution system. Failure of drinking water systems could lead to water shortages. Raw sewage, dead bodies in the water and release of dangerous chemicals into the floodwaters could lead to the spread of disease through contact with contaminated water and to infection through open wounds. Houston has at least a dozen sites that have been designated environmentally hazardous, so there is a risk of petrochemical contamination. Indeed, companies have reported that pollutants from refineries have already been released. As if those are not bad enough, the “unprecedented” amount of water leads to the perfect breeding opportunities for mosquitoes, which are vectors of Zika and many other infectious diseases.

  • Harnessing AI to catch disease fast

    Up to 27,000 microbiology laboratories around the world could benefit from a ground-breaking automation technology. The Automated Plate Assessment System (APAS) can automatically screen microbiology culture plates for the presence of various disease-causing pathogens, revolutionizing the workflow in modern microbiology labs. The smart software uses artificial intelligence to analyze microbial growth in much the same way as a microbiologist would, but with faster and more consistent results.

  • 139 countries could be powered by 100 percent wind, water, and solar energy by 2050

    The latest roadmap to a 100 percent renewable energy future from twenty-seven experts is the most specific global vision yet, outlining infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; a net increase of over twenty-four million long-term jobs; an annual decrease in 4-7 million air pollution deaths per year; stabilization of energy prices; and annual savings of over $20 trillion in health and climate costs.
