arcticstoat writes "A new graphics company called Caustic Graphics reckons it's uncovered the secret of real-time ray tracing with a chip that 'enables your CPU/GPU to shade with rasterization-like efficiency.' The new chip basically off-loads ray tracing calculations and then sends the data to your GPU and CPU, enabling your PC to shade a ray-traced scene much more quickly. Caustic's management team isn't afraid to rubbish the efforts of other graphics companies when it comes to ray tracing. 'Some technology vendors claim to have solved the accelerated ray tracing problem by using traditional algorithms along with GPU hardware,' says Caustic. However, the company adds that 'if you've ever seen them demo their solutions you'll notice that while results may be fast — the image quality is underwhelming, far below the quality that ray tracing is known for.' According to Caustic, this is because the advanced shading and lighting effects usually seen in ray-traced scenes, such as caustics and refraction, can't be accelerated on a standard GPU because it can't process incoherent rays in hardware. Conversely, Caustic claims that the CausticOne 'thrives in incoherent ray tracing situations: encouraging the use of multiple secondary rays per pixel.' The company is also introducing its own API, called CausticGL, which is based on OpenGL/GLSL, which will feature Caustic's unique ray tracing extensions."

draevil writes "BBC News reports that the novel "Skylon" spaceplane design of British firm Reaction Engines has received funding to proceed with its proof-of-concept design for an air-breathing rocket engine. If successful, the Sabre rocket engine will be able to take the Skylon with 12 tonnes of cargo from a runway, to orbit and then back to that runway without the need for disposable components or a piggy-back ride on a larger aircraft. Should the design prove viable, it could see first use within ten years."

suraj.sun writes "US regulators are examining Apple Inc.'s disclosures about Chief Executive Officer Steve Jobs's health problems to ensure investors weren't misled, a person familiar with the matter said. The Securities and Exchange Commission's review doesn't mean investigators have seen evidence of wrongdoing, the person said, declining to be identified because the inquiry isn't public. Bloomberg News reported last week that Jobs is considering a liver transplant as a result of complications after treatment for cancer, according to people who are monitoring his illness."

Gamasutra is running an article discussing the influence of games and gamers on the 2004 and 2008 presidential elections. The connection, while minor, is continuing to strengthen, from allowing people to register to vote through their consoles, to in-game advertising, to games about and involving the candidates. However, it may still be an uphill climb as media-sharing becomes easier. From Gamasutra: "There are reasons games have grown slowly compared to other technologies for political outreach. The most important one is also the most obvious: since 2004, online video and social networks have become the big thing, as blogs were four years ago. Instead of urging voters to 'play my game,' as Loftus and I surmised, candidates urged their constituents to 'watch my video.' Online video became the political totem of 2008, from James Kotecki's dorm room interviews to CNN's YouTube debates."

SamBob writes "Future releases of the most popular BitTorrent client, Azureus, will come bundled with a 'platform' for media companies to promote their product to Azureus' multi-million users, reports Slyck.com. Azureus Inc., who are the newly formed company behind the Azureus software, plan to generate a profit from the platform in the future, but in the short-term are hoping to help independent film companies find their audience."
