• NY to buy, demolish beachfront homes, make way for storm buffers

    New York governor Andrew Cuomo plans to use $400 million in federal funding to buy beachfront homes as part of a broader plan to reshape the New York coastline so the state is better prepared for sea level rise, surges, and storms. The plan is to raze the purchased homes and leave to shore front vacant. Some properties would be turned into dunes, wetlands, or other natural buffers. Other parcels could be combined and turned into public parkland.

  • Miles tax may soon replace gas tax as a way to fund infrastructure maintenance

    With infrastructure around the country in a state of disrepair, many states and lawmakers are trying to find a way to fund improvement of  roads and bridges. The federal gasoline tax brings in fewer dollars each year, and now some lawmakers and transportation experts are considering the idea of taxing citizens by how far they drive each year instead of the amount of gasoline they buy each year.

  • Springfield, Illinois, faces infrastructure woes

    As is the case with other cities, the infrastructure of Illinois’ capital, Springfield, is decaying. Experts told the city council that it would take $86.6 million over the next three years to shore up the city’s streets and sewer system, and $22.5 million a year thereafter to maintain it. The city is now grappling with how to raise the necessary funds.

  • Climate change threatens public health, safety, economy along U.S. coasts

    A new technical study from the U.S. National Oceanic and Atmospheric Agency (NOAA) and the U.S. Geological Survey (USGS) reports that the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities’ social, economic, and natural systems. All U.S. coasts are highly vulnerable to the effects of climate change such as sea-level rise, erosion, storms, and flooding, especially in the more populated low-lying parts of the U.S. coast along the Gulf of Mexico, Mid-Atlantic, northern Alaska, Hawaii, and island territories. The report says that the financial risks associated with both private and public hazard insurance are expected to increase dramatically.

  • Osaka Basin quake map identifies high-rise buildings at risk

    The Osaka Basin, Japan is home to many high-rise buildings which sit atop its thick soft sediments, vulnerable to long-period strong ground motions that last minutes. A new map created by Japanese researchers is intends to guide engineers and city planners in new construction and identifies existing buildings with the potential of resonance vibration.

  • New bridge construction technologies to shore up U.S. infrastructure

    See video

    Experts agree that there is an urgent need to construct and repair bridges across the United States. Around 70,000 bridges in the country are considered “structurally deficient” by government standards. New technology could help the United States manage its growing, and aging, infrastructure without breaking the bank or levying high taxes on citizens.

  • Extreme rainfall linked to global warming

    A worldwide review of global rainfall data has found that the intensity of the most extreme rainfall events is increasing across the globe as temperatures rise. In the most comprehensive review of changes to extreme rainfall ever undertaken, researchers evaluated the association between extreme rainfall and atmospheric temperatures at more than 8,000 weather gauging stations around the world.

  • Pentagon to bolster U.S cyberwar capabilities

    The Department of Defense is planning an expansion of the U.S. Cyber Command, and the Pentagon plans on recruiting thousands of code crackers, online security professionals, and hackers in order to assemble the nation’s largest cyber army ever.

  • Maryland counties debate funding stormwater drainage management

    A new tax aimed at property owners could finance the first set of improvements of the drainage works in Salisbury, Maryland since the original system was laid almost a century ago. City leaders have been arguing since 2009 over dedicating a source of funding to stormwater management, when an environmental panel recommended it. In the past, funding for projects like this has been hard to find as other priorities were deemed more important.

  • Grammar rules undermine security of long computer passwords

    When writing or speaking, good grammar helps people make themselves understood. When used to concoct a long computer password, however, grammar — good or bad — provides important hints that can help someone crack that password, researchers at Carnegie Mellon University have demonstrated by devising grammar-aware password cracker.

  • Improving cities by using the notion of “urban metabolism”

    As is the case with organisms, cities need energy, water, and nutrients, and they need to dispose of wastes and byproducts in ways which are viable and sustainable over the long run. This concept of “urban metabolism” is a model for looking systematically at the resources that flow into cities and the wastes and emissions that flow out from them in order better to understand the environmental impacts of cities and to highlight opportunities for efficiencies, improvements, and transformation.

  • Exploring asteroids for commercial metal harvesting

    Deep Space says that in a decade, it will be harvesting asteroids for metals and other building materials, to construct large communications platforms to replace communications satellites, and later solar power stations to beam carbon-free energy to consumers on Earth. “More than 900 new asteroids that pass near Earth are discovered every year. They can be like the Iron Range of Minnesota was for the Detroit car industry last century,” says the company’s CEO.

  • DOE addresses rare earth, critical materials shortage

    The U.S. Department of Energy announced earlier this month that a team led by Ames Laboratory in Ames, Iowa, has been selected for an award of up to $120 million over five years to establish an Energy Innovation Hub which will develop solutions to the domestic shortages of rare earth metals and other materials critical for U.S. energy security.

  • Black carbon’s contribution to climate change underestimated

    Black carbon is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this issue; black carbon is believed to have a warming effect of about 1.1 Watts per square meter (W/m²), approximately two thirds of the effect of the largest man made contributor to global warming, carbon dioxide.
