• Industry insiders: insufficient security controls for smart meters

    False data injection attacks exploit the configuration of power grids by introducing arbitrary errors into state variables while bypassing existing techniques for bad measurement detection; experts say current generation of smart meters are not secure enough against false data injection attacks

  • Stormy weather in Europe's future

    Europeis likely to be hit by more violent winter storms in the future; a new study into the effects of climate change has found out why

  • 2012 National Collegiate Cyber Defense Competition kicks off 20 April

  • U.S. power and water utilities face daily cyberattacks

    American water and energy companies deal with a constant barrage of cyberattacks on a daily basis; these incidents usually take the form of cyber espionage or denial-of-service attacks against the utilities’ industrial-control systems

  • Cyberweapon blowback

     

    The real concern about Stuxnet is that its existence demonstrates what is achievable; security analysts are confident that they can stop anything that is a variant of Stuxnet, but the real challenge is stopping something in the style of Stuxnet; this is where the confidence ends

  • Containing a tunnel flood with an inflatable giant plug

    Researchers have developed a giant plug to contain tunnel floods; the plug inflates (with water or air) to dimensions of roughly 32-feet-long and by 16-feet-wide, and holds 35,000 gallons, about the same capacity as a medium-sized backyard swimming pool

  • New laws help cut metal thefts

    Metal thefts have become a plague to businesses throughout the country; some states pass laws which require licenses and permits to buy and sell non-ferrous metals; Spartanburg, South Carolina, also requires that buyers pay for the purchases with checks rather than cash, in order to create a paper trail to the seller of the metal

  • A swarm of small satellites to deflect menacing asteroids

    New research suggests that the best way to divert an asteroid hurtling toward Earth is using a swarm of relatively small satellites flying in formation and cooperatively firing solar-powered lasers onto an asteroid; this would be a more effective way than the current methods being contemplated, which are focused on large unwieldy spacecraft

  • 1930s technology to become 21st century tool against CO2 emissions

    Human activity releases 30 billion tons of carbon dioxide into the air each year; a new approach to dealing with the problem has a back-to-the-future glint, leveraging technology that the petroleum industry has used since the 1930s to remove carbon dioxide and other impurities from natural gas

  • Dueling legislation over cybersecurity regulations

     

    Attacks on U.S. critical infrastructure may bring about a Katrina-like situation: no electricity, no fresh water, limited traffic control, severely curtailed emergency response, and more; about 85 percent of U.S. critical infrastructure is privately owned; two different cybersecurity bills in Congress envision different solutions to U.S. infrastructure’s cyber vulnerability

  • Confirmed: oil from Deepwater Horizon disaster entered food chain

    For months, crude oil gushed into the water at a rate of approximately 53,000 barrels per day; new study confirms that not only did oil affect the ecosystem in the Gulf during the blowout, but it was still entering the food web after the well was capped

  • Asteroid to miss Earth next year, but not by much

    When it whizzes past Earth in 2013, a newly discovered asteroid is going to miss our planet — but not by much; the 50-meter space rock is expected to come closer than many satellites, highlighting the growing need to keep watch on hazards from above

  • NICB warns of growing copper thefts

    A recently released report by the National Insurance Crime Bureau (NICB) concludes that copper and other metal thefts are on the rise once again in the United States

  • U.S. files trade charges against China over rare minerals

    China mines and sells about 97 percent of the world’s rare Earth elements – seventeen metals used in cell phones, advanced batteries, wind turbines, and more; the Chinese, in  violation of WTO rules, have manipulated the export of these minerals in order to weaken the techno logy sectors of other countries, and punish countries over political disputes

  • Millions of Americans at risk of flooding as sea levels rise

    Nearly four million Americans, residing in a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests; in terms of population, Florida is the most vulnerable, closely followed by Louisiana, California, New York, and New Jersey
