     ...The A350 XWB is Airbus’ answer to the Boeing 787, complete with carbon fiber fuselage and wings–a first for a passenger jet. And to avoid the issues that have plagued the Dreamliner, Airbus is in the process of testing four prototype A380 “eXtra-wide” planes. And part of that testing involves the just-revealed interior.

  • Low levels of the hormone cortisol may identify teen drivers with a high likelihood of getting into car accidents, suggests a small new study. Newly-licensed teens who produced high cortisol under stress were less likely to be involved in a crash or a near-crash, the researchers found. Measuring cortisol might make a good test to flag young drivers in need of extra safety training, they conclude.

  • A new tool to help local governments and regional planners evaluate the impact of policy-relevant variables on vehicle miles traveled — taking into account the unique attributes of each community — is available online, the California Air Resources Board announced today.  This tool offers look-up tables that provide neighborhood-scale VMT elasticities and marginal effects associated with changes in land use and transportation variables for city, county and regional geographic areas.

  • Laboratory chamber walls have been stealing vapors, causing researchers to underestimate the formation of secondary organic aerosol in the atmosphere. A study published April 7 in PNAS Online Early Edition describes how a team of scientists, including researchers from the University of California, Davis, showed that vapor losses to the walls of laboratory chambers can suppress the formation of secondary organic aerosol, which in turn has contributed to the underprediction of SOA in climate and air quality models.

  • New draft rules limiting greenhouse gases from existing power plants will give states the tools to curtail emissions that drive climate change without shuttering lots of facilities and threatening electric reliability, said Gina McCarthy, the administrator of the Environmental Protection Agency, at a panel discussion in Washington on Monday. “Nothing we do can threaten reliability,” McCarthy said at a conference hosted by the Bipartisan Policy Center, a Washington think tank, especially because “in a changing climate, it will be increasingly challenging to maintain a reliable energy supply.”

  • As many as 900 street parking spaces - one of San Francisco's most precious commodities - will be reserved for car-sharing vehicles and leased at discounted rates. The parking program, which will begin in the summer, is a two-year experiment that aims to spread car sharing throughout the city...Half of the street spaces - 450 - will be available starting in the summer. They'll be marked with signs and paint and assigned to a specific vehicle. Primus said they'll be spread around the city, which was a goal of the program.

  • Q: Gary, you stated that a carpool lane ticket was not a moving violation and didn't affect insurance premiums. I say, "Au contraire!" At least, USAA didn't go along with that. Back in the good old days, when I was commuting with "Henri," my companion dummy, I finally got nailed by a motorcycle cop. All I could say was: "Officer, desperate men do desperate things." They raised my premiums for three years!
