• Erratic Weather Slows Down the Economy

    If temperature varies strongly from day to day, the economy grows less. Through these seemingly small variations climate change may have strong effects on economic growth. In a new study, researchers  juxtapose observed daily temperature changes with economic data from more than 1,500 regions worldwide over 40 years – with startling results.

  • Swarming Drones Concept Flies Closer to Reality

    A swarm of twenty drones has recently completed the largest collaborative, military-focused evaluation of swarming uncrewed aerial vehicles (UAVs) in the U.K. The exercise was the culmination of the Defense Science and Technology Laboratory’s (DSTL) “Many Drones Make Light Work” competition

  • Robot Seeks Out Chemical Agents

    Scientists have successfully tested a fully autonomous robot that will help defense and security personnel dealing with hazardous scenes. The development of the robot means that humans and machines can now share the burden of detecting and report dangerous chemicals over large areas.

  • Climate Change May Have Driven the Emergence of SARS-CoV-2

    Global greenhouse gas emissions over the last century have made southern China a hotspot for bat-borne coronaviruses, by driving growth of forest habitat favored by bats.

  • Pandemic Shows Need for Biological Readiness

    By Andy Weber

    President Joe Biden’s inauguration comes during the worst stage of the deadliest biological event of our lifetimes. As bad as this pandemic is, imagine if instead it were caused by the deliberate release of a sophisticated biological weapon. About 2 percent of those infected have died of COVID-19, while a disease such as smallpox kills at a 30 percent rate. A bioengineered pathogen could be even more lethal. Our failed response to the pandemic in 2020 has exposed a gaping vulnerability to biological threats, ranging from natural outbreaks to deliberate biological weapons attacks.

  • Unifying U.S. Atmospheric Biology Research to Prevent Risks to National Security

    Global circulating winds can carry bacteria, fungal spores, viruses and pollen over long distances and across national borders, but the United States is ill-prepared to confront future disease outbreaks or food-supply threats caused by airborne organisms. In the United States, research and monitoring of airborne organisms is split between an array of federal agencies. The lack of coordination and information-sharing can effectively cripple the U.S. response to national security threats, such as pandemics.

  • Study: Rethink Immigration Policy for STEM Doctorates

    By James Dean

    A streamlined process for awarding green cards to international STEM doctoral students graduating from U.S. universities could benefit American innovation and competitiveness, including leveling the field for startups eager to attract such highly skilled workers, according to a new study.

  • Why Projects to Adapt to Climate Change Backfire

    Many internationally funded projects aimed at combating the impacts of climate change can make things worse - by reinforcing, redistributing, or creating new sources of vulnerability in developing countries, according to a new study.

  • Role of Dams in Reducing Global Flood Risks under Climate Change

    Flood is amongst the costliest natural disasters. Globally, flood risk is projected to increase in the future, driven by climate change and population growth. The role of dams in flood mitigation, previously unaccounted for, was found to decrease by approximately 15 percent the number of people globally exposed to historical once-in-100-year floods, downstream of dams during the twenty-first century.

  • Aging Dams Pose Growing Threat

    By 2050, most people on Earth will live downstream of tens of thousands of large dams built in the twentieth century, many of them already operating at or beyond their design life. Increasingly expensive to maintain, experts foresee a trend to decommissioning dams.

  • Most U.S. Social Studies Teachers Feel Unprepared to Teach Civic Learning, a Gap Contribute to Truth Decay

    Only one in five social studies teachers in U.S. public schools report feeling very well prepared to support students’ civic learning, saying they need additional aid with instructional materials, professional development, and training, according to a RAND Corporation survey.

  • Developing First Responder Emergency Alerts Technology

    As emergency communications technologies adapt to an increasingly interconnected nation, DHS S&T announced it awarded more than $1.5 million to develop an Alerts, Warnings, and Notifications (AWN) Guidance Tool.

  • Managing Extreme Weather Events with artificial intelligence

    Can combining deep learning (DL)— a subfield of artificial intelligence— with social network analysis (SNA), make social media contributions about extreme weather events a useful tool for crisis managers, first responders and government scientists?

  • Lunar Gold Rush Could Create Conflict on the Ground If We Don’t Act Now – New Research

    By Tony Milligan

    Many countries and private companies have ambitious plans to explore or mine the Moon. This won’t be at some remote point in time but soon – even in this decade. So far, much of the debate around exploring and mining the Moon has focused on tensions in space between state agencies and the private sector. But as we see it, the pressing challenge arises from limited strategic resources.

  • Earth to Reach Temperature Tipping Point in Next 20 to 30 Years

    Earth’s ability to absorb nearly a third of human-caused carbon emissions through plants could be halved within the next two decades at the current rate of warming, according to a new study. Researchers have identified a critical temperature tipping point beyond which plants’ ability to capture and store atmospheric carbon—a cumulative effect referred to as the “land carbon sink”—decreases as temperatures continue to rise.
