We summarize the week's scientific breakthroughs every Thursday.
- 			 Tech TechCleanup Speedup: Device improves oil-spill recoveryBy adding grooves to the surface of a common oil-skimming device, researchers recovered up to three times as much oil as they do with smooth-surfaced devices. 
- 			 Tech TechUnstoppable Bot: Armed with self-scrutiny, a mangled robot moves onRoboticists have made a walking machine that carries on despite serious damage. By Peter Weiss
- 			 Tech TechThe Little Chill: Tiny wind generator to cool microchip hot spotsBy generating a tiny cooling wind, a microscale silicon needle armed with a powerful electric field has demonstrated its potential as a new way to cool increasingly hot microchips. By Peter Weiss
- 			 Tech TechTeasing Apart Nanotubes: Fast-spun carbon fibers may feed an industryResearchers have devised a way to sort carbon nanotubes by size and electronic properties. By Peter Weiss
- 			 Tech TechMuscling up colors for electronic displaysResearchers have found a way to provide the complete color palette for television and computer screens. By Peter Weiss
- 			 Tech TechLong-Sought Laser? Standard microchips may gain speedy optical connectionsAlthough not made exclusively of silicon, a new type of laser runs on electricity and could be mass manufactured in the same factories as silicon microchips are. By Peter Weiss
- 			 Tech TechStart your enginesMechanical engineers have developed a system that greatly decreases the amount of toxic hydrocarbons a car releases. By Eric Jaffe
- 			 Tech TechA thin laser gets thinnerResearchers have created a microchip laser that fires an extraordinarily thin beam of high-intensity light. By Peter Weiss
- 			 Tech TechCyber attack depletes cell phone batteriesIn a new type of cyber attack, assailants using computers connected to the Internet can secretly induce distant cell phones to rapidly deplete their batteries. By Peter Weiss
- 			 Tech TechSize Matters: Biosensors behave oddly when very smallThere might be a limit to how small physicists should build tiny sensors that detect viruses and molecules. By Eric Jaffe
- 			 Tech TechWheel of Life: Bacteria provide horsepower for tiny motorCrawling bacteria can power a micromotor. By Peter Weiss
- 			 Tech TechThe ups and downs of routing fluids on chipsA new way to build microscale pipes in three dimensions boosts the sophistication of chips that manipulate fluids to perform chemical reactions and other tasks. By Peter Weiss
