• Using the Internet of Things for Water Security

    A cluster of internet-enabled devices, including a water-flow sensor, pH sensor, ultrasonic sensor, and “PIC” microcontroller, may be used together as a watchdog system for water quality.The simple and low-cost system being developed by the team of researchers in India makes water quality assessment and water security widely available without the need for sophisticated technical knowledge.

  • Interim Report on U.S. and AI Released to Congress

    The National Security Commission on Artificial Intelligence (NSCAI) released its Interim Report last week. “As NSCAI’s report conveys, U.S. leadership in promoting trust and innovation in artificial intelligence is imperative to the future of our nation’s security and economy,” said Michael Kratsios, Chief Technology Officer of the United States.

  • Misguided Immigration Policies Are Endangering America’s AI Edge

    The efforts to foster America’s development of artificial intelligence, including for military use, typically overlook how the U.S. current advantage depends on immigrants. “Without immigration reforms, this country’s days as the world’s AI leader may be numbered,” Zachary Arnold writes. “Immigration reform of any sort may be a tall order nowadays, but the dawn of the AI age is reason enough to redouble those efforts,” he adds.

  • Florida’s Building Code Doesn’t Take Sea Rise into Account. That Could Change This Year.

    The last time the Florida building code changed, in 2016, it required any new construction along the coast to elevate buildings by one foot. Three years later, this does not look to be enough. Experts call for going up yet another foot. Alex Harris notes that elevating the base of homes is a clear sign that political debates over climate change notwithstanding, “the people who plan and build in coastal Florida consider the threat of sea rise very real.”

  • Beijing Will Give You Cold War Nostalgia

    America’s twenty-first-century competition with China is likely to be more dangerous and more complex than the U.S. Cold War with the Soviet Union. Walter Russell Mean writes that this is the result of two factors: First, China’s economic power makes it a much more formidable and resourceful opponent than the Soviet Union was., and, second, the technological environment has changed dramatically in the past generation.

  • National Labs Host DOE CyberForce Competition

    Five teams of college students will square off at the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) on 16 November as part of DOE’s fifth CyberForce Competition. The event, held simultaneously at ten of the DOE’s National Laboratories across the United States, will challenge 105 college teams to defend a simulated energy infrastructure from cyberattacks. The CyberForce Competition is designed to inspire and develop the next generation of energy sector cybersecurity professionals by giving them a chance to hone their skills during interactive and realistic scenarios.

  • Rising Seas Threaten Low-Lying Coastal Cities, 10 percent of World Population

    A new report from the Coalition for Urban Transitions finds that, because sea level rise exacerbates flooding and storm surge, it is a critical threat to urban coastal areas. More than 10 percent of the world’s population now resides in urban centers or quasi-urban clusters situated at less than 10 meters above sea level.

  • Promoting Cooperation Between Humans, Autonomous Machines

    The trust between humans and autonomous machines is a top priority for U.S. Army researchers — as machines become integral to society, it is critical to understand the impact on human decision-making.

  • What Causes Steel Corrosion in Reinforced Concrete

    Since the Egyptian pyramids and the Roman Coliseum were built, mankind has been searching for an affordable, versatile building material, that can be easily manufactured and transported, and, above all, which is durable. Concrete has all these characteristics, but there is a problem: the corrosion of steel bars that internally strengthen structures made of reinforced concrete. This situation causes rapid, internal deterioration of frames and may even lead to buildings collapsing.

  • New Reactor Designs Will Degrade Waste More Rapidly

    Renewed interest in nuclear power as a viable option for generating electricity has been accompanied by steady progress in reactor design. Advanced reactors offer the promise of greater fuel efficiency and less radioactive waste generation compared with the water-cooled models that have dominated the nuclear power landscape for decades. Newer designs, however, will operate at higher temperatures and use highly corrosive coolants — like liquid metal, molten salt, or high-temperature gas — all of which would rapidly degrade many of the materials used in conventional nuclear reactors.

  • Hurricanes in U.S. Have Become Bigger, Stronger, More Destructive

    A new study shows that hurricanes have become more destructive since 1900, and the worst of them are more than three times as frequent now than 100 years ago. A new way of calculating the destruction, compensating for the societal change in wealth, unequivocally shows a climatic increase in the frequency of the most destructive hurricanes that routinely raise havoc on the North American south- and east coast.

  • How Scientists Got Climate Change So Wrong

    Few thought it would arrive so quickly. Now we’re facing consequences once viewed as fringe scenarios. Had a scientist in the early 1990s suggested that within 25 years a single heat wave would measurably raise sea levels, at an estimated two one-hundredths of an inch, bake the Arctic and produce Sahara-like temperatures in Paris and Berlin, the prediction would have been dismissed as alarmist. But many worst-case scenarios from that time are now realities.

  • Plants Demand More Water as Climate Warms, Leaving Less for People

    As climate changes, plants in North America, much of Eurasia, and parts of central and South America will consume more water than they do now, leading to less water for people, according to a new study. The research suggests a drier future despite anticipated increases in precipitation in populous parts of the United States and Europe that already face water stresses.

  • World Scientists Declare Climate Emergency

    A global coalition of scientists says “untold human suffering” is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change. In a paper published in BioScience, the authors, along with more than 11,000 scientist signatories from 153 countries, declare a climate emergency, present graphics showing trends as vital signs against which to measure progress, and provide a set of effective mitigating actions.

  • California Wildfires Signal the Arrival of a Planetary Fire Age

    Another autumn, more fires, more refugees and incinerated homes. For California, flames have become the colors of fall. Stephen Pyne writes that free-burning fire is the proximate provocation for the havoc, since its ember storms are engulfing landscapes. But in the hands of humans, combustion is also the deeper cause. Modern societies are burning lithic landscapes - once-living biomass now fossilized into coal, gas and oil - which is aggravating the burning of living landscapes. “Add up all the effects, direct and indirect – the areas burning, the areas needing to be burned, the off-site impacts with damaged watersheds and airsheds, the unraveling of biotas, the pervasive power of climate change, rising sea levels, a mass extinction, the disruption of human life and habitats – and you have a pyrogeography that looks eerily like an ice age for fire,” he writes. “You have a Pyrocene. The contours of such an epoch are already becoming visible through the smoke. If you doubt it, just ask California.”
