Science & Technology

You know you've made the big time when Saturday Night Live parodies your product. On last weekend's show, Fred Armisen demonstrated Google Glass, the all-the-rage wearable computer the tech giant has been testing with the help of volunteers. Let's just say that Armisen, as Weekend Update tech correspondent Randall Meeks, finds a few flaws in the device.

Watch the video. (And maybe plan on adding a neck brace to your future Google Glass purchase order).

The Solar Impulse, an airplane traveling across the United States using only solar power, is in Phoenix today, after reaching Arizona from California Saturday. It took the plane about 20 hours to travel from Mountain View, Calif., near San Francisco.

The aircraft is capable of flying at night as well as in daytime; the plane had about 75 percent of its battery power remaining when it landed in Arizona.

A cruise run by the Aquarium of the Pacific in Long Beach, Calif., sounds like a picturesque summer outing. But the Urban Ocean boat cruise highlights the juxtaposition of a powerful port with a fragile ecosystem: You're just as likely to see trash as you are to see marine life.

In front of the aquarium, school kids are running around, eager to go inside and pet the sharks and see the penguins. There's also a marina, where a small passenger boat called the Cristina shoves off from sunny Shoreline Aquatic Park.

In fall 2011, Sebastian Thrun, a research professor at Stanford, and Peter Norvig, the top scientist at Google, teamed up to develop and teach a free, online course on artificial intelligence. Their aim, as Norvig said in an impassioned and compelling TED talk, was to develop a course at least as good as, if not better than, the course they teach together at Stanford. They'd put the result online and make it available to everyone, for free.

The Earth's wettest regions are likely to get wetter while the most arid will get drier due to warming of the atmosphere caused by increased levels of carbon dioxide, according to a new NASA analysis of more than a dozen climate models.

When the Great Storm of 1900 battered Galveston, Texas, the town simply lifted itself up--in some places as much as 17 feet. Could a similar approach save cities today? Randy Behm of the US Army Corps of Engineers and Dwayne Jones of the Galveston Historical Foundation talk about the costs and feasibility of raising a town, albeit with better technology than Galveston's hand-cranked jacks and mules.
