SLIPS liquid repeller is inspired by carnivorous plants, enemy to insects and graffiti artists alike
When a team of Harvard researchers wanted to create the ultimate liquid- and solid-repelling surface, they looked toward the Nepenthes pitcher plant, where curious insects check in and never check out, thanks to slippery walls that lead to their tiny, horrific fate. The tropical plant inspired the creation of SLIPS (Self-healing, Slippery Liquid-Infused Porous Surface), a synthetic material that utilizes nano/ microstructured substrates, capable of repelling just about anything you can throw at it. During a visit to the hallowed Crimson halls, the team was kindly enough to show off the material through a series of messy, messy demos, dropping water, motor oil, liquid asphalt and newly-mixed concrete on aluminum and glass. The team even went crazy with a can of black spray paint, comparing the results to a Teflon surface. The outcome was the same in all case -- an amazingly repellent material. The team has published a number of papers on the stuff, including ones that demonstrate its ice- and bacteria-repelling properties. Oh, and like its natural inspiration, SLIPS does a great jobs keeping bugs off its surface. You can check out our demos and one unhappy ant filmed by the SLIPS team. No insects were harmed in the making of our video, at least -- and the lab assures us that ant had a good life before learning the hard way why it shouldn't mess with Harvard scientists.
Preview of new Guitar Hero II co-op mode
In case you missed it on Friday, IGN posted a pre-E3 hands-on preview of Guitar Hero II's new co-op mode. It's a departure from the first game's multiplayer mode in that the two players have to depend on each other a lot more to pass each song and thereby make beautiful music together.While the old multiplayer option will still be around in the sequel, the new mode mixes distinct lead guitar and bass or rhythm parts where each player affects the other in various ways, whether by failing if either performance slips (as in DDR), sharing the same Rock Meter (with mistakes from either player resetting the score multiplier), and needing to both go vertical at the same time to activate the shared Star Power. Thankfully, different difficulty levels can be assigned to each player.The Joystiq team out in L.A. will probably find something to do until they get their sweaty paws on a guitar controller or two on the E3 show floor (maybe one of those wacky press conferences will help pass the time), but we're sure the wait to try the latest build of this rockin' series will be worth it. The seven songs available at E3 are listed below.[Thanks, murph]
