• Fukushima-derived radioactivity in seafood poses minimal health risks

    Researchers find that the likely doses of radioactivity ingested by humans consuming fish contaminated by radioactive radiation escaping from the debilitated Fukushima reactors fish, are comparable to, or less than, the radiological dosages associated with other commonly consumed foods, many medical treatments, air travel, and other background sources.

  • U.S. unlikely to meet its biofuel goals

    The Energy Independence and Security Act of 2007 (EISA) mandates that by 2022 the United States derive fifteen billion gallons per year of ethanol from corn to blend with conventional motor fuels.

  • Current methods of reducing arsenic contamination of water are not effective

    Arsenic is now recognized to be one of the world’s greatest environmental hazards, threatening the lives of several hundred million people. Naturally occurring arsenic leaches into water from surrounding rocks and once in the water supply it is both toxic and carcinogenic to anyone drinking it. New research finds that most of the current technologies used around the world to reduce arsenic contamination are ineffective.

  • California Democratic lawmakers want a go-slow approach to fracking

    California may be on the verge of an oil rush. It is estimated that hydraulic fracturing, or fracking, at the Monterey Shale formation may tap reserves of fifteen billion barrels of oil.

  • Mitigating fires in the wildland-urban interface

    More than forty-six million residential structures in about 70,000 communities in the United States are located in the so-called wildland-urban interface (WUI). On average, WUI fires destroy 3,000 buildings annually. They accounted for six of the ten most costly fires in the United States over the last 100 years. Five of these fires occurred in California, where the incidence of wildfires currently is up 47 percent this year over last.

  • Relying on natural gas-fired generators during electric grid failures

    Natural gas-fired electricity generators can provide energy security at domestic military installations in the event of electric grid failures. A study found there is minimal risk of interrupted deliveries for a moderate outage (two weeks to three months).

  • Improving “crop per drop” boosts global food security, water sustainability
