• Warming Climate Intensifies Summer Drought in Parts of U.S.

    Climate change is amplifying the intensity and likelihood of heatwaves during severe droughts in the southern plains and southwest United States, according to a new study. The findings raise the idea of a self-reinforcing climate loop: as a region’s climate becomes more arid due to climate change, droughts become hotter, further reducing soil moisture.

  • Raising Tough Questions about Retreat from Rising Seas

    As the global thermostat climbs and polar ice melts, the oceans are swelling and swallowing up coastlines. By some calculations, rising seas could displace 13 million Americans by 2100. While some communities are attempting to adapt in place with elevated buildings and seawalls to divert water, relocation appears inevitable for many.

  • Preventing West Antarctic Ice Collapse by Snowing Ocean Water onto It

    The ice sheet covering West Antarctica is at risk of sliding off into the ocean. The slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilized. A collapse will raise sea levels worldwide by more than three meters. Researchers are now scrutinizing a daring way of stabilizing the ice sheet: Generating trillions of tons of additional snowfall by pumping ocean water onto the glaciers and distributing it with snow canons.

  • Helping first responders deal with dirty bombs

    If a radiological dispersal device (RDD), or “dirty bomb,” ever explodes in the United States, emergency crews may be better prepared because researchers have developed a new simulator, which show first responders what an optimal response to an RDD would look like.

  • Fighting anthrax by removing the bacterium’s armor

    Anthrax is a deadly and highly resilient disease, caused by the spore-forming bacterium Bacillus anthracis. Historically, it was a major cause of death in humans and cattle. has shown that removing the armor of the bacterium that causes anthrax slows its growth and negatively affects its ability to cause disease.

  • Predicting flood duration

    The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Researchers now offer a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding.

  • California’s Wildfires Are 500 Percent Larger Due to Climate Change

    Californians may feel like they’re enduring an epidemic of fire. The past decade has seen half of the state’s 10 largest wildfires and seven of its 10 most destructive fires, including last year’s Camp Fire, the state’s deadliest wildfire ever. A new study finds that the state’s fire outbreak is real—and that it’s being driven by climate change. Since 1972, California’s annual burned area has increased more than fivefold, a trend clearly attributable to the warming climate. “Each degree of warming causes way more fire than the previous degree of warming did. And that’s a really big deal,” Park Williams, a climate scientist at Columbia University and an author of the paper, said. Among the many ways climate change might be messing with the environment, extra heat is among the simplest and most obvious. “Heat is the most clear result of human-caused climate change,” Williams said.

  • DHS S&T announces $35M Funding for Terrorism Prevention, Counterterrorism Research

    The rapidly evolving, diverse terrorist threat continually exploits technological advances to adapt the nature and expand the reach of its tactics. DHS S&T announces $35 million funding opportunity for Terrorism Prevention and Counterterrorism Research (TPCR). TPCR will support academic-led innovation that supports DHS in staying a step ahead of emerging terrorist tactics.

  • Climate Change Is Driving Many California Wildfires

    Against a backdrop of long-term rises in temperature in recent decades, California has seen ever higher spikes in seasonal wildfires, and, in the last two years, a string of disastrous, record-setting blazes. This has led scientists, politicians and media to ponder: what role might warming climate be playing here?

  • Can the “Masters of the Flood” Help Texas Protect Its Coast from Hurricanes?

    After centuries of fighting back water in a low-lying nation, the Dutch have become the world leaders in flood control. And their expertise is helping Texas design what would become the nation’s most ambitious — and expensive — coastal barrier.

  • Southwest to Endure 50 Days or More a Year When Temperature “Feels Like” Exceeding 105 Degrees

    Increases in potentially lethal heat driven by climate change will affect every state in the contiguous U.S. in the decades ahead. Few places would be unaffected by extreme heat conditions by midcentury and only a few mountainous regions would remain extreme heat refuges by the century’s end. The dangerously soaring heat across the U.S. is posing unprecedented health risks.

  • The Coming AI Metamorphosis

    Humanity is at the edge of a revolution driven by artificial intelligence. This revolution is unstoppable. Attempts to halt it would cede the future to that element of humanity more courageous in facing the implications of its own inventiveness. Instead, we should accept that AI is bound to become increasingly sophisticated and ubiquitous, and ask ourselves: How will its evolution affect human perception, cognition, and interaction? What will be its impact on our culture and, in the end, our history?

  • Do Patents Protect National Security?

    On 12 June, the Wall Street Journal broke the story that Chinese firm Huawei Technologies Co. had asserted more than 200 patents against Verizon Communications Inc., reportedly demanding more than $1 billion in licensing fees. On its face, this would seem to be a private patent dispute. But, in fact, it is an important turn of events for national security: The Verizon-Huawei dispute contradicts a view espoused by many experts, and even the Trump administration, about the relationship between national security and intellectual property rights such as patents.

  • Timber Skyscrapers Can Rewind the Carbon Footprint of the Concrete Industry

    Recent innovations in engineered timber have laid the foundations for the world’s first wooden skyscrapers to appear within a decade, a feat that is not only achievable, but one they hope will beckon in an era of sustainable wooden cities, helping reverse historic emissions from the construction industry.

  • California Plans to Better Use Winter Storms to Refill Its Aquifers

    With new rules coming into effect, California farmers and municipalities using groundwater must either find more water to support the aquifers or take cropland out of use. To ease the pain, engineers are looking to harness an unconventional and unwieldy source of water: the torrential storms that sometimes blast across the Pacific Ocean and soak California.
