SubComdTaco passes along news of researchers in the US who have trapped a rainbow in a tapering waveguide. The research is described (PDF) on the arXiv. "In 2007, Ortwin Hess of the University of Surrey in Guildford, UK, and colleagues proposed a technique to trap light inside a tapering waveguide [made of metamaterials]... The idea is that as the waveguide tapers, the components of the light are made to stop in turn at ever narrower points. That's because any given component of the light cannot pass through an opening that's smaller than its wavelength. This leads to a 'trapped rainbow.' ... Now Vera Smolyaninova of Towson University in Baltimore, Maryland, and colleagues have used a convex lens to create the tapered waveguide and trap a rainbow of light. They coated one side of a 4.5-mm-diameter lens with a gold film..., and laid the lens — gold-side down — on a flat glass slide which was also coated with film of gold. Viewed side-on, the space between the curved lens and the flat slide was a layer of air that narrowed to zero thickness where the lens touched the slide — essentially a tapered waveguide. When they shone a multi-wavelength laser beam at the... gilded waveguide, a trapped rainbow formed inside. This could be seen as a series of colored rings when the lens was viewed from above with a microscope: the visible light leaked through the thin gold film."

2K Games has revealed information about the multiplayer portion of BioShock 2, which will be developed by Digital Extremes. Multiplayer will be a prequel story that takes place prior to Rapture's fall, where "players assume the role of a Plasmid test subject for Sinclair Solutions, a premier provider of Plasmids and Tonics in the underwater city of Rapture that was first explored in the original BioShock." The press release says players will gain experience points which they can spend to gain access to "new Weapons, Plasmids and Tonics that can be used to create hundreds of different combinations, allowing players to develop a unique character that caters to their playing style." It will also expand on the BioShock story.

mr_sifter writes "Three years ago, celebrity gamers such as Fatal1ty were bagging millions in prizes, and TV channels were queuing up to broadcast games on TV. Professional gaming looked set for the big time. It never happened, and in the current economic crisis, sponsors and media organizations are cutting costs, resulting in the closure of many pro gaming competitions (as we recently discussed) and a down-scaling in prize money. This feature looks at whether pro gaming can bounce back, and whether it will always be a PC sport, or if pro gaming on consoles is the future."
