• Increasing Hydrogen Energy Requires All Technologies to Be Pushed Forward

    No single hydrogen technology should be prioritized, says a new study, and the production, distribution, and use of hydrogen needs to be optimized.

  • Extreme Rain Heads for California’s Burn Scars, Raising the Risk of Mudslides – This Is What Cascading Climate Disasters Look Like

    Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Such consecutive events lead to human disasters. Studies show climate change is raising the risk of multiple compound disasters.

  • Biden Administration Places Climate Change at the Center of U.S. Security Planning

    The administration on Thursday has released a series of reports addressing the increasingly severe impact of climate change on U.S. national security – an impact which is only going to grow in severity and scope. Taken together, the reports signal a new stage in U.S. policy, one which places climate change at the center of the U.S. security planning.

  • Rising Temperatures Reshaping, Exacerbating Global Security Landscape

    More than just altering the environment, climate change is threatening to permanently and dangerously reshape the global security landscape. These are the conclusions of a series of new assessments by U.S. military, intelligence, and security officials. “As climate change converges with other drivers — especially geostrategic competition, emerging technology and global-demographic trends — it is reshaping the risk landscape,” DHS said in its assessment. “The corrosive impact of these trends will make nations increasingly vulnerable to domestic instability, with sweeping implications for regional and border security and core national security interests.”.

  • Weapons-Detection Algorithm Studied at Las Vegas International Airport

    This summer, DHS S&T demonstrated a new advanced algorithm to better detect non-explosive weapons like guns, knives, and other items that are prohibited on commercial aircraft in a real-world setting at Las Vegas’ McCarran International Airport.

  • Urbanites Face Heightened Flood Risk as a Result of Forest Loss

    The devastating impact of flooding in Queensland’s north, exacerbated by forest loss, is badly affecting urban areas. Researchers found that deforestation near urban areas exposes these areas to much larger amounts of water flowing on the soil surface soon after a rainfall.

  • Cities Worldwide Aren’t Adapting to Climate Change Quickly Enough

    Climate change is magnifying threats such as flooding, wildfires, tropical storms and drought. cities are quickly becoming more vulnerable to extreme weather events and permanent shifts in their climate zones. The problem is that the pace of climate change is accelerating much more rapidly than urban areas are taking steps to adapt to it.

  • Nuclear War's Smoke Would Cause Climate Change, Threatening Global Food Supplies

    Nuclear war would cause many immediate fatalities, but smoke and soot from the resulting fires would also cause climate change lasting up to fifteen years, threatening worldwide food production and human health, according to a new study.

  • How Marsh Grass Protects Shorelines

    As climate change brings greater threats to coastal ecosystems, new research can help planners leverage the wave-damping benefits of marsh plants.

  • Growing the U.S. AI Workforce

    A new policy brief Georgetown University’s Center for Security and Emerging Technology (CSET) addresses the need for a clearly defined artificial intelligence education and workforce policy.

  • Quick Detection of Uranium Isotopes Helps Safeguard Nuclear Materials

    Researchers have developed a rapid way to measure isotopic ratios of uranium and plutonium collected on environmental swipes, which could help International Atomic Energy Agency analysts detect the presence of undeclared nuclear activities or material.

  • U.S. Hit with $18 Billion Weather and Climate Disasters So Far This Year

    The United States saw an unprecedented eighteen separate billion-dollar weather and climate disasters in the first nine months of the year, September 2021 was the 5th-warmest September on record.

  • Enough with the Quackery, Pinker Says

    “Another contributor [to the opposition to vaccines] is the Myside bias, probably the most powerful of all the cognitive biases, namely, if something becomes an article of faith within your own coalition, and if promoting it earns you status, that is what you believe,” says Harvard’s professor of psychology Steven Pinker, whose latest book — Rationality: What It Is, Why It Seems Scarce, Why It Matters – has just been published. “It’s somewhat arbitrary which positions get attached to which coalitions…. It used to be the tree-hugging Mr. and Ms. Naturals who were suspicious of vaccines — a romantic opposition to science and tech made vaccine resistance a leftish cause. But now it’s more attached to the right. In either case, people are more adamant about protecting the sacred beliefs of their political tribe than looking at the best evidence.”

  • Making Desalinated Water Safer, Cheaper

    Approximately 80 percent of drinking water in Israel is desalinated water, coming from the Mediterranean Sea. Israeli scientists and colleagues develop an effective and low-cost way to remove toxic boron from water in the process of desalination.

  • Forensic Analysis of Lipstick Trace

    Forensic scientists find a new way of identifying brands of lipstick at a crime scene without removing evidence from its bag.
