Tech soothsayers have long predicted the demise of computers as we know them today, as their shrinking sizes approach the limits of silicon's ability to take the heat. Now, researchers at Stanford University - in the heart of Silicon Valley - have tossed the essential element aside and built a basic computer out of carbon nanotubes. The engineering feat, described this week in the journal Nature, could herald the birth of a whole new generation of carbon-based computing devices, experts said.

Look out M3 fans: a turbo is coming. Confirming what had long been rumored, BMW announced Wednesday the next generation of its venerated M3 sedan (and M4 coupe) would indeed use a turbocharged engine for the first time in the model's history. The duo are mechanically identical. However, for the first time, BMW is positioning the 4-Series coupes as slightly more upmarket from their 3-Series sedan brethren, similar to what it's done with the 5-Series sedans and 6-Series coupe models.

A study released by the Motion Picture Assn. of America is taking aim at Google, alleging the Internet giant and other search engines are making it too easy for consumers to find pirated content online -- even when they're not looking for it. A study released Wednesday by the MPAA, the trade group representing the major Hollywood studios, concludes that search is a major gateway to the initial discovery of pirated movies and TV shows. The survey found that 74% of consumers surveyed cited using a search engine as a navigational tool the first time they arrived at a site with infringing content, even when the consumer was not looking for pirated movies or TV shows.

While Los Angeles moves through the 21st century, much of its landscape remains locked up in 1940s concrete. The storm drain and flood channel that was and will again be the Los Angeles River is a case in point. The good folks at the U.S. Army Corps of Engineers were heroes to the Los Angeles of the mid-20th century for controlling the river's periodic rages. It's hard to remember, when looking at the high concrete walls of the channel today, that the trickle of water in the bottom can go so wild so suddenly that in times past the river jumped its banks and emptied in various places along the shore - in what is now Marina del Rey or Seal Beach, for example - as often as at its now-fixed mouth at the Port of Long Beach.

As state air pollution officials step up inspections of diesel exhaust from big rigs, some of their best allies are truckers themselves. They are pushing the Air Resources Board to enforce pollution rules more aggressively for trucks in advance of a Jan. 1 deadline. Truckers are also the No.1 tipsters, placing anonymous calls and sending emails to finger competitors they say are gaining an unfair advantage by not upgrading their engines or installing expensive filters that capture harmful diesel particulates before they are released into the air. Diesel exhaust is the worst remaining pollution source on roadways.

After seven years of study, federal officials have recommended a $453-million plan that would restore an 11-mile stretch of the Los Angeles River but leave much of its banks steep and hard to reach, disappointing advocates who hoped for a more ambitious alternative that would allow more public access. The tentative plan selected by the U.S. Army Corps of Engineers, known as Alternative 13, is the second-cheapest of four options detailed in a much-anticipated feasibility study released Friday.

Before an audio revolution in the mid-1960s, just about all music, dialogue and other sounds played on tape recordings had one thing in common: hiss. The bothersome, underlying noise seemed especially unavoidable during quiet passages on the once-ubiquitous cassette tapes. But then came an engineering breakthrough that nearly wiped out the hiss, and made the inventor's name - Dolby - world-famous. Ray Dolby, 80, died Thursday at his home in San Francisco. The company he founded, Dolby Laboratories, released a statement saying he had been suffering from Alzheimer's disease in recent years and in July was found to have acute leukemia.

Young Guru has helped everyone from Jay Z to Beyoncé to Drake to Eminem to Kanye West shape their sounds. Now, the Grammy Award-nominated engineer-DJ-producer will shape minds at USC as an artist-in-residence for the coming academic year, the university announced Tuesday. The prolific engineer, born Gimel Keaton, will join the faculty of USC Thornton's Contemporary Music Division, where he will work with students in the popular music, music industry and music technology programs. During his post at USC, he will be instrumental in helping the university develop a degree program in music production and will also lecture students studying hip-hop, electronic music, music industry and songwriting.

SCHWENKSVILLE, Pa. - Engineers think that three of the bridges closest to Dave Wisler's home are about ready to collapse. One, a picturesque one-lane structure built in 1893, became so perilous it was closed last summer, and the county doesn't have the money to fix it. Another bridge, just down the road, is well-known for the concrete that chips off the bottom as children play in the creek below - it's currently under repair. Traffic was diverted to a third bridge nearby, but some drivers noticed a worrying humming noise as they drove over it, and their windows rattled.

Americans might soon need to get used to apple or grape juice as their breakfast drink of choice - unless, that is, they're willing to pay exorbitant prices for orange juice. Or maybe scientists, plant breeders and farmers will manage to save the day, using two critical but often-disparaged technologies: chemical pesticides in the short run and genetic engineering in the longer term. The pestilence that is devastating Florida citrus is a disease called citrus greening. It is caused by a bacterium, Candidatus Liberibacter asiaticus , which is spread by small insects called psyllids.
