• Seacoast roads under new threat from rising sea level

    Research has found that some roads, as far as two miles from the shore, are facing a new hazard that currently cannot be seen by drivers - rising groundwater caused by increasing ocean water levels. Without drastic improvements to these routes, at or below the pavement surface, motorists can expect segments of these roadways to deteriorate more quickly, require more maintenance and be closed for longer periods of time.

  • Taller wind turbine towers to help expand wind energy nationwide

    Winds at higher elevations, generally, are stronger and more consistent, even in wind-rich states such as Iowa and Texas. In fact, a 20-meter increase (about 66 feet) in tower height creates a 10 percent boost in Iowa energy production. Researchers have been working on developing new concrete tower technology capable of reaching 140 meters (about 459 feet). The towers will be assembled from precast panels and columns made with high-strength or ultra-high-performance concrete. Those panels and columns can be cast in sizes that are easy to load on trucks. They are tied together on-site by cables to form hexagon-shaped cells. A crane can stack the cells to form towers as high as 140 meters.

  • Mass trauma’s emotional toll can disrupt children’s sense of competence

    Traumatic events can have a profound effect on communities. Whether it is a terrorist attack or a natural disaster, such as a hurricane or tornado, the aftermath can have lasting effects, especially on children. How children respond in the wake of mass traumatic events is related to their perceptions of competence – or how they view their ability to control a situation. An overwhelming challenge, such as a natural disaster or a terrorist attack, can disrupt the development of that sense of well-being.

  • Frequency of coastal flooding will double globally in next decades

    The frequency and severity of coastal flooding throughout the world will increase rapidly and eventually double in frequency over the coming decades even with only moderate amounts of sea level rise, according to a new study. The new report shows that with just 10 to 20 cm (4 to 8 inches) of sea level rise expected no later than 2050, coastal flooding will more than double. This dramatic increase in coastal flooding results from rising sea levels combined with storm-driven flooding, including the effects of waves and storm surge.

  • Strong carbon price needed to drive large-scale climate action: Economists

    Meeting the world’s agreed climate goals in the most cost-effective way while fostering growth requires countries to set a strong carbon price, with the goal of reaching $40-$80 per ton of CO2 by 2020 and $50-100 per ton by 2030. This is the key conclusion of the High-Level Commission on Carbon Prices, led by Nobel Laureate Joseph Stiglitz and Lord Nicholas Stern. The study concludes that a well-designed carbon price is an indispensable part of a strategy for efficiently reducing greenhouse gas emissions while also fostering growth.

  • Middle school engineers show their skills in electric car competition

    Chicago-area middle school students showcased their engineering talents of at the annual Electric Car Competition this spring. The quest: construct a fully functioning model electric car that could travel a 20-meter track while carrying a two-pound load. The task challenged students to apply the same science and engineering principles used by professional engineers every day.

  • Climate change likely to increase risk of costly storms in U.K.

    The impact of climate change on the United Kingdom is likely to mean a higher number of more expensive wind storms, the insurance industry warned. New analysis done for the Association of British Insurers (ABI) shows temperature increases of just a small number of degrees are likely to lead to insurance losses for high winds which could be 11 percent, 23 percent, or even 25 percent higher nationwide.

  • Mobile phones can reveal exposure to radiation

    In accidents or terror attacks which are suspected to involve radioactive substances, it can be difficult to determine whether people nearby have been exposed to radiation. But by analyzing mobile phones and other objects which come in close contact with the body, it is possible to retrieve important information on radiation exposure.

  • Educating, strengthening the cybersecurity workforce

    As Americans become more dependent on modern technology, the demand to protect the nation’s digital infrastructure will continue to grow. CSU, designated as Centers of Academic Excellence in Information Assurance by the NSA and DHS, says that in an effort to produce career-ready cybersecurity professionals and to combat cybercrime nationwide, the California State University is creating educational opportunities for students and faculty members.

  • DHS S&T’s Transition to Practice program unveils 2017 cohort

    Eight new cybersecurity technologies developed by researchers at federally funded laboratories and academic research centers are ready for the commercial market. DHS S&T’s Transition to Practice (TTP) program will showcase its 2017 cohort 16 May in Washington. D.C.

  • Right research, development investments “good bets” for both climate and economies

    Investing in new ways of utility-scale electricity storage and capturing carbon to store underground should be a priority for governments aiming to meet the greenhouse gas and “green energy” targets set out in the Paris Agreement despite shrinking research and development budgets, experts suggest. Researchers analyzed a range of studies and expert reports on public energy R&D investments to uncover common threads and trends — pulling together the current state of knowledge on cost-effective investments across a range of energy technologies.

  • Tipping points: When natural or social systems reach a point of no return

    A tipping point is a critical threshold at which a dynamical system undergoes an irreversible transformation, typically owing to a small change in inputs or parameters. This concept is very broad and can refer to the extinction of an animal or a plant species, the depletion of a water source, or the financial collapse of an institution, among many other natural and social phenomena. Researchers provide a better understanding of the characteristics of this point of no return and what happens to a system after its occurrence.

  • Helping power utilities and others better plan for the future

    If you’re an electric utility planning a new power plant by a river, it would be nice to know what that river will look like twenty years down the road. Will it be so high that it might flood the new facility? Will the water be so low that it can’t be used to cool the plant? Generally, such projections have been based on records of past precipitation, temperature, flooding and other historical data. But in an era when temperature and precipitation are changing rapidly, historical patterns won’t do you much good. A new initiative by the U.S. Department of Energy’s (DOE) Argonne National Laboratory combines climate data and analysis with infrastructure planning and decision support, promises real help.

  • AgTech innovator raises $7.5 million to help develop precision agriculture

    Today, the Ag industry loses more than $300 billion each year due to crop diseases and pests. Pests and diseases can destroy crops and devastate farmers’ agricultural yield, but chemical overuse comes with its own set of challenges, including pesticide-resistant disease strains. Meanwhile, rising temperatures and increasing levels of carbon dioxide create more challenges for farmers as crop pests and disease thrive in hot, CO2-rich environments. Taranis, a precision agriculture intelligence platform, announced it has closed a $7.5 million Series A round of financing. Taranis says it aims to lead the digital farming revolution by giving farmers around the globe the ability to predict and prevent detrimental threats to their crops—and bottom line.

  • Dangerous mix: Climate change, tornadoes, and mobile homes

    Tornadoes and mobile homes do not mix to begin with, but throw in the volatility of climate change and the potential for massive property damage and deaths is even higher in coming decades. The number of mobile homes in the United States has risen dramatically in the past 60 years, to about 9 million currently. Meanwhile, the United States is the most tornado-prone country in the world, with an average of 1,200 twisters per year.
