• Clear tactics, if only few easy solutions, for hospitals tackling ransomware

    Hospitals facing the prospect of ransomware attacks like the one that afflicted British hospitals in May can take many concrete steps to better protect themselves, but some of the most important measures — such as a national policy not to pay ransoms — may be tougher to formulate.

  • Drones could save lives in disaster zones

    Research from the University of South Australia has shown for the first time that drones can be used to detect human vital signs in war zones and natural disasters. The researchers have successfully trialed unmanned aerial vehicles to measure heart and respiratory rates using remote-sensing imaging systems, while hovering three meters from humans.

  • 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.

  • 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.

  • 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.

  • DNA sequencing tools vulnerable to cybersecurity risks

    Rapid improvement in DNA sequencing has sparked a proliferation of medical and genetic tests that promise to reveal everything from one’s ancestry to fitness levels to microorganisms that live in your gut. A new study finds evidence of poor computer security practices used throughout the field. Researchers have also demonstrated for the first time that it is possible — though still challenging — to compromise a computer system with a malicious computer code stored in synthetic DNA. When that DNA is analyzed, the code can become executable malware that attacks the computer system running the software.

  • Biomedical research community should build resilience to disasters

    The academic biomedical research community should improve its ability to mitigate and recover from the impacts of disasters, says a new report from the National Academies of Sciences. The consequences of recent disasters, from hurricanes to cyberattacks, have shown that the investments of the U.S. federal government and other research sponsors — which total about $27 billion annually — are not uniformly secure. “Continuing scientific advancement and the promise of future discoveries will require a commitment to resilience — and an unparalleled partnership across the emergency management and academic research sectors,” says one of the report’s authors.
