Rydberg Molecule Created For the First Time 127

krou writes "The BBC is reporting that the Rydberg molecule has been formed from two atoms of rubidium. Proven in theory, this is the first time it's been created, reinforcing the fundamental quantum theories of Enrico Fermi. Chris Greene, the theoretical physicist who first predicted that the Rydberg molecules could exist, said: 'The Rydberg electron resembles a sheepdog that keeps its flock together by roaming speedily to the outermost periphery of the flock, and nudging back towards the centre any member that might begin to drift away.' It's a sheepdog with a very short life-span, however; the longest lived molecule only lasted 18 microseconds. Vera Bendkowsky, who led the research, explained how they created the molecule: 'The nuclei of the atoms have to be at the correct distance from each other for the electron fields to find each other and interact. We use an ultracold cloud of rubidium — as you cool it, the atoms in the gas move closer together. We excite the atoms to the Rydberg stage with a laser. If we have a gas at the critical density, with two atoms at the correct distance that are able to form the molecule, and we excite one to the Rydberg state, then we can form a molecule.'"

Ugobe, Maker of Pleo, Files For Bankruptcy 79

AshboryBassPlayer writes "Ugobe has filed for Chapter 7 bankruptcy — i.e., not reorganization but liquidation. We first discussed the company's Pleo robotic dinosaur toy in 2006. According to the company, 100,000 Pleos were sold in 2008. CEO Caleb Chung is optimistic about the auction value of intellectual property that Ugobe holds. Pleo featured 14 servo joints, a camera, and an SD Card for storage. The final street prices were commonly between $275 and $350, much higher than an earlier hoped-for price point under $200."

Ditto. Synergy rules my 4 machine world.

Ubuntu box on the left, Windows box center, Fedora Right, MacBook pro down and to the left. All the screens are linked intuitively (that is, move the cursor to the edge towards the machine you want, and BOOM you're there).

PLUS, synergy keeps a common clipboard between all your machines (text only) so you can copy something from one machine and paste it to the other. I can't live without it now.
