writes "Applied physicists at the Harvard have created an ultrathin, flat lens that focuses light without the distortions of conventional lenses.
“Our flat lens opens up a new type of technology,” says principal investigator Federico Capasso. “We’re presenting a new way of making lenses. Instead of creating phase delays as light propagates through the thickness of the material, you can create an instantaneous phase shift right at the surface of the lens. It’s extremely exciting.”"Link to Original Source
writes "My N900 recently broke and I'm looking for a replacement. The N9 looks great, despite not having a keyboard, but it seems that it will not have as many packages and developer interest as the N900. The iPhone is not an option as a matter of principle. I've never used Android before, and am a bit bewildered by the number of choices. Is there any particular phone the Slashdot crowd would recommend as a worthy replacement for the N900 both in functionality and spirit? Or should I wait for Tizen phones to appear?"
writes "One Chinese company has proposed new buses that are so big they straddle the road, while cars drive beneath them. Designers at Shenzhen Hashi Future Parking Equipment Co., Ltd say that these behemoth buses solve a number of issues in one fell swoop, and would result in fewer traffic jams, less emissions, and faster travel.
These buses are actually being put into pilot use shortly. They should make their debut in Beijingâ½âsÂâs Mentougou district, where work is to commence on the first 186km of track at yearâ½âsÂâs end.
Each of the jumbo buses will measure 4 to 4.5 meters high, with passengers aboard the upper level and other vehicles lower than 2 meters going under. Powered by electricity and solar energy, the bus can carry 1,200 to 1,400 passengers at a time."Link to Original Source
