• Building security into cyber-physical systems

    We are immersed in a cyber-physical world. Information technology is deeply embedded in traditionally non-IT systems, including automobiles, the electric grid and emergency response. But in many of these systems, security is largely incorporated as a last step, like a suit of armor over a vulnerable body. To help bake security into the very core, a new draft NIST publication recommends ways to incorporate time-tested security design principles and concepts into these systems at every step, from concept to implementation.

  • Floods, coastal erosion may expose contents of UK landfills

    The contents of historic coastal landfill sites in England and Wales could pose a significant environmental threat if they erode, according to a new study. The main risks to these landfills come from the effects of climate change, including erosion and flooding with salt water from storm surges and higher water levels.

  • Protecting Texas electrical grid key to preserving national security

    Protecting America’s most vulnerable asset – our electric power grid – starts with Texas, according to a new study. “As Texas goes, so goes our national security,” says the study’s author. “Outside of California and the Beltway, Texas is arguably the most important state for defense readiness.” Hardening the state’s electric power grid should be top priority.

  • “Internet of Things” increases threat to infrastructure

    According to former Director of National Intelligence Dennis Blair, a simple Web search can reveal information from thousands of unsecured devices. Even the casual browser can access camera data from Sweden, video game server activity in Eastern Europe, or the output of American wind turbines. He said this information is as easily accessible to terrorists and other criminals. And more will become available as the “Internet of things” — the collection of physical systems and devices connected to the Internet — grows in size.

  • Fixing NYC’s aging infrastructure one engineering problem at a time

    How do you make sure aging bridges which are vital links in New York City’s transportation network are safe or keep the city’s sewer system from breaking down? These are among the questions that occupy Columbia University researchers, who have installed sensors to analyze vibration on some of the city’s bridges and in landmark buildings and museums, and have focused on the functioning of the city’s water system.

  • More corrosion-resistant water pipes could preventing another Flint, Mich. health crisis

    Corrosion-related damage costs more than three percent of the United States’ Gross Domestic Product (about $503.1 billion, going by 2013 numbers). With documented public water problems in Flint, Michigan, and Hoosick Falls, New York, caused by corrosion, understanding how copper is affected at the atomic level is critical to avoiding problems in future pipes.

  • Repairing earthquake-damaged bridge columns in days, not weeks

    In just thirty seconds, a devastating earthquake like the ones that struck Japan and Ecuador can render a city helpless. With roadways split and bridges severely damaged, residents and emergency personnel could be prevented from moving around to rebuild. Normally, it takes weeks to repair the cracking or spalling of columns on just one bridge damaged in an earthquake. Researchers have developed a new process of fixing columns that takes as little as a few days.

  • Rising seas put Vietnam in the “bull’s eye” of rising seas

    A rising sea level — for a country like Vietnam, with 2,000 miles of coastline — presents a major environmental and food security challenge, especially in the Mekong River Delta region where 22 percent of the population lives and about half of the country’s food is produced.

  • “G-Science” academies call for strengthening global disaster resilience

    In the decade between 2005 and 2014, more than 6,000 natural and technological disasters occurred around the world, killing more than 0.8 million people, displacing millions more, and costing more than $1 trillion. Losses due to disasters are increasing in both developed and developing countries. Human factors that increase exposure and vulnerability, such as poverty, rapid population growth, disorderly urbanization, corruption, conflict and changes in land use, poor infrastructure including non-engineered housing, together with effects of climate change on weather patterns with increased extreme events, aggravate the negative consequences of natural and technological hazards.

  • New Web portal for coastal resilience

    William & Mary Law School and William & Mary’s Virginia Institute of Marine Science (VIMS) are collaborating on a new Web site which will provide key information to support local, regional, and state efforts to adapt to sea-level rise. Tidal and storm surge flooding risks, FEMA flood zone maps, storm history, and critical infrastructure risk assessments are all topics that are likely to be included on the Web site. Information about conditions of shorelines, wetlands, beaches, and coastal forests will also be in the portal.

  • Robot offers safer, more efficient way to inspect power lines

    Currently, line crews have to suit up in protective clothing, employ elaborate safety procedures, and sometimes completely shut off the power before inspecting a power line. It can be difficult, time-consuming, and often dangerous work. Researchers have invented a robot which could change the way power lines are inspected — providing a safer and more cost-effective alternative.

  • FBI, DHS warn grid operators about cyber threats to power grid

    The FBI and DHS are warning infrastructure operators about the potential cyberattacks on the U.S. power grid. The FBI and DHS have launched a nationwide campaign to alert power companies and security firms, a campaign which includes briefings and online Webinars.

  • Microgrids to enhance diversity, reliability, resilience

    For more than 100 years, the United States electrical grid operated on a one-way delivery model: power generation, transmission, and distribution in response to user demand. Electricity came from big coal-fired plants and hydroelectric dams, later supplemented by nuclear and natural gas plants, and went out to the world as a mix of baseload and peaking power. With more renewable energy integration, smaller-scale and more widely distributed energy resources, and a demand for increased reliability and resilience, the grid of the future is shaping up to be a two-way power flow, with demand adapting more and more to available supply.

  • Global warming of 2.5°C degrees would put at risk trillions of dollars of world’s financial assets

    An average of $2.5 trillion, or 1.8 percent, of the world’s financial assets would be at risk from the impacts of climate change if global mean surface temperature rises by 2.5°C (4.5°F) above its pre-industrial level by 2100, according to a new study. that the authors found, however, that uncertainties in estimating the “climate Value at Risk” mean that there is a 1 percent chance that warming of 2.5°C could threaten $24 trillion, or 16.9 percent, of global financial assets in 2100.

  • Analyzing the effects of rising sea levels in Norfolk, Va.

    In Norfolk, Virginia, an East Coast city which is home to the world’s largest naval station and important seaports, catastrophic flooding could damage more than homes and roads. A new study from Sandia National Laboratories assesses how much the city, its region, and the nation would suffer in damages to national assets and lost economic activity if it does nothing to address rising sea levels. The analysis method is available to cities that want to become more resilient.
