• Policy Decisions' Effect on Migration from Sea Level Rise

    A new modeling approach can help researchers, policymakers and the public better understand how policy decisions will influence human migration as sea levels rise around the globe. “Sea level rise is going to reorganize the human population around the globe,” says one researcher.

  • Using Hemp to Repair Deteriorating Kentucky Bridges

    Bridges are a crucial component of Kentucky’s infrastructure — providing access between regions and cities and linking workers to jobs. But as traffic continues to increase, bridges across the state are aging at an accelerated pace. Experts say that 7 percent of Kentucky’s bridges—or 1,100 bridges — are classified as “structurally deficient.” Researchers have developed innovative products — dubbed CatStrong — for restoring bridges.

  • Lack of Preparation Hampers Protection against Bushfires

    As Australia confronts devastating bushfire conditions, people across the nation are doing all they can to ensure the safety of their homes, property and loved ones. But while many individuals are responding well to bushfire risks, a lack of preparation on the community level could be hampering their efforts, according to a new research.

  • FCC Bans Use of Federal Funds in Purchases of Chinese Telecom

    The Federal Communications Commission (FCC) on 22 November blocked U.S. telecommunications providers from using an $8.5 billion subsidy fund – the FCC’s Universal Service Fund (USF) — to buy Chinese-made telecommunications gear deemed a national security threat to critical infrastructure. The U.S. said that given Huawei and ZTE’s close relationship and legal obligations to the Chinese government, their gear poses a threat to telecommunications critical infrastructure, as well as to national security.

  • Studying Large Storm to Help Lessen Their Impact on Coasts

    When cyclones or other massive oceanic storms make landfall, their giant waves batter coastlines and sometimes cause widespread damage. Researchers have analyzed months of data of large nearshore waves to provide new insights that could help improve the designs of a variety of coastal structures from seaports to seawalls to better withstand destructive waves.

  • Beavers to help U.K. Flood Management

    Having once been an important part of the ecosystem, beavers became extinct in the United Kingdom in the sixteenth century due to hunting for their fur, meat and scent glands. The U.K. National Trust has announced plans to release Eurasian beavers at two sites in the south of England next spring to help with flood management.

  • 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.

  • Switching to Renewable Energy May Save Thousands of Lives in Africa

    With economies and populations surging, an industrial revolution is inevitable on the African continent. The question is, what’s going to power it? With renewable energy cheaper and more efficient than ever, countries in Africa have the unique opportunity to harness abundant renewable sources like wind, solar and geothermal to leapfrog the dependence on fossil fuels that has poisoned the air and environment in Europe, the U.S., India and China. But will they?

  • Lessons from the Cyberattack on India’s Largest Nuclear Power Plant

    In early September, a cyberattack occurred at the Kudankulam nuclear power plant in India. The Indian nuclear monitoring agency finally admitted that the nuclear plant was hacked, and on 30 October Indian government officials acknowledged the intrusion. “As the digitalization of nuclear reactor instrumentation and control systems increases, so does the potential for malicious and accidental cyber incidents alike to cause harm,” Alexander Campbell and Vickram Singh write.

  • 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.”

  • 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.

  • 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.

  • Operations in French Nuclear Power Plant Suspended after Monday Tremor

    Following a strong earthquake Monday in the Drôme and Ardèche regions in south-east France, EDF (Électricité de France) has ordered the suspension of power production at the Cruas-Meysse power station. The magnitude 5.4 earthquake shook the area at 11:52 a.m. Monday. Of France’s nineteen active nuclear power plants, five plants are located in seismically active zones.

  • 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.

  • Dams Across the U.S. Pose Potential Risk

    A more than two-year investigation by the Associated Press has found scores of dams around the United States in various states of disrepair, located in areas where a breach might place thousands in danger. These aging dams loom over homes, businesses, highways, or entire communities which could face life-threatening floods if the dams don’t hold. The Association of State Dam Safety Officials estimates it would take more than $70 billion to repair and modernize the nation’s more than 90,000 dams. But unlike much other infrastructure, most U.S. dams are privately owned. That makes it difficult for regulators to require improvements from operators who are unable or unwilling to pay the steep costs.
