• U.S. states agree on plan to manage overtaxed Colorado River

    Seven Southwestern U.S. states that depend on the overtaxed Colorado River have reached landmark agreements on how to manage the waterway amid an unprecedented drought, including a commitment by California to bear part of the burden before it is legally required to do so.

  • Climate change requires a fresh approach to water woes

    Climate change is affecting the Everglades and other large watersheds across the United States in new and unpredictable ways. Extreme weather events and rising sea levels, combined with a growing population, will lead to “more intense arguments” about already contested issues of water quality and water usage, experts say.

  • Protecting the power grid from cyberattacks

    As the national power grid becomes increasingly dependent on computers and data sharing—providing significant benefits for utilities, customers, and communities—it has also become more vulnerable to both physical and cyber threats. While evolving standards with strict enforcement help reduce risks, efforts focused on response and recovery capabilities are just as critical––as is research aimed at creating a well-defended next generation smart grid.

  • U.S. carbon-capture network could double global CO2 headed underground

    With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to researchers.

  • Why it’s unwise for the U.K. to boast about its cyberattack capability

    The U.K. government is very publicly investing more money in its ability to conduct cyberattacks and, at the same time, it is becoming increasingly open in talking about the attacks it has conducted in the past – and those it might conduct in future. There are risks involved in publicly signaling the imminence of cyber and other attacks, especially against capable adversaries with a demonstrable appetite for taking risks and a cavalier attitude about collateral damage. The U.K. needs to think more carefully about how it integrates cyber operations, and communication about them, into its wider approach – not only towards Russia but across the whole spectrum of national security operations.

  • Economic benefit of NIST’s encryption standard at least $250 billion

    NIST has released a study that estimates a $250 billion economic impact from the development of its Advanced Encryption Standard (AES) over the past twenty years. AES is a cryptographic algorithm used to encrypt and decrypt electronic information. It was approved for use by the federal government in November 2001 and has since been widely adopted by private industry. Today, AES protects everything from classified data and bank transactions to online shopping and social media apps.

  • U.S. prepared to strike in cyberspace

    The United States is prepared to go on the offensive in cyberspace to ensure adversaries know there is a price to pay for hacks, network intrusions and other types of attacks. President Donald Trump signed a new National Cyber Strategy on Thursday, calling for a more aggressive response to the growing online threat posed by other countries, terrorist groups and criminal organizations.

  • A bridge over the Strait of Gibraltar? New bridge forms span farther

    A bridge’s span is the distance of suspended roadway between towers, with the current world record standing at just under 2km. Newly identified bridge forms could enable significantly longer bridge spans to be achieved in the future, potentially making a crossing over the Strait of Gibraltar, from the Iberian Peninsula to Morocco, feasible.

  • New SAFETY Act best practices guide to commercial building security

    A new web-based tool can help security professionals for commercial office buildings perform assessments based on the Best Practices for Anti-Terrorism Security (BPATS) for commercial office buildings.

  • Revisiting federal safety regulations for liquid petroleum gas distribution systems

    Current federal safety regulations for small distribution systems used for propane and other liquefied petroleum gases (LPGs) should be improved for clarity, efficiency, enforceability, and applicability to risk, says a new report from the National Academies of Sciences.

  • Climate change: we need to start moving people away from some coastal areas, warns scientist

    Climate change has forced a paradigm shift in the way coastal flooding and erosion risks are managed. In areas of lower risk, adaptation plans are being devised, often with provisions to make properties and infrastructure more resilient. Adaptation may involve requiring raised foundations in flood-prone areas or the installation of mitigating measures, such as sustainable drainage systems. Building codes may also be established to make structures more disaster-proof and to control the types of constructions within risk zones. But such adaptation options are often of limited use or unsuitable for high-risk areas. In such areas relocation is the only safe climate-proof response.

  • 32 dead, 500,000 homes without power, Wilmington virtually cut off

    Emergency crews have been busy Monday and today in many cities across the Carolinas as both residents and the authorities were trying to cope with the aftermath of a record rainfall. The water damaged tens of thousands of homes, and floodwaters may not recede for days. Even as the remnants of Hurricane Florence pulled away, it was clear that the turmoil had only begun.

  • Hurricanes can cause enormous damage inland, but emergency plans focus on coasts

    Coastal residents also prepare for major storms by building homes elevated above anticipated high water levels, in order to minimize damage and qualify for flood insurance. And building codes commonly call for reinforced construction to endure high wind speeds. All of these sensible and essential preparations focus on wind and storm surge in coastal zones. Today, however, risk from hurricanes is extending inland. Some of the worst damage from Eastern Seaboard hurricanes in the past several decades has come from inland flooding along rivers after storms move ashore.

  • When is a sea wall a good idea?

    Recent hurricanes like Maria and Sandy have brought crippling winds, torrential rains, and flooding to vulnerable coastal regions, in some cases killing thousands of people. Sea walls and other barriers are often suggested as a way of protecting these low-lying coastal communities, but how large should such a wall be, and where is the most effective place to build it? Environmental scientists and researchers is trying to answer these questions and more, to help curb the devastation from future hurricanes.

  • Keeping buildings functioning after natural disasters

    After an earthquake, hurricane, tornado or other natural hazard, it’s considered a win if no one gets hurt and buildings stay standing. But an even bigger victory is possible: keeping those structures operational. This outcome could become more likely with improved standards and codes for the construction of residential and commercial buildings.
