The book Halo Effect is an intriguing title that takes a look Bungie's best-selling Halo titles from a number of different angles. Each chapter includes coverage of specific elements; included are descriptions of pro events, a bit on the development process, and the making of the Red vs. Blue series. One of the most interesting chapters takes a look at the science behind the Halo world, talking about the physics and logic behind ringworlds and the hi-tech weaponry seen in the game. Thanks in part to a mini-review of the book on the GameSetWatch site, Gamasutra has been allowed to reprint the entire 'science of Halo' chapter on their website. "A 5,000 kilometer radius would yield a circumference of roughly 31,400 kilometers. If we assume a width-to-radius ratio similar to that of Niven's Ringworld, they would be approximately 5.37 kilometers wide. They are significantly wider, though, at 320 kilometers. The Halos, then, would have a surface area of 10 million square kilometers - slightly larger than the surface area of Canada, and approximately 2 percent of the surface area of Earth. Of course, since we know that there are lakes, seas, and rivers on the Halos, the livable surface area would be fractionally less."

sporkme writes "A scientist was frustrated when the compound she was working with (called PPAR-gamma) destroyed her sample of cancer cells. Further research revealed that the substance was surprisingly well suited as a cancer treatment. Lab test results on mice resulted in the destruction of colon tumors without making the mice sick." Quoting: "'I made a calculation error and used a lot more than I should have. And my cells died,' Schaefer said. A colleague overheard her complaining. 'The co-author on my paper said, "Did I hear you say you killed some cancer?" I said "Oh," and took a closer look.' ... [They found that the compound killed] 'pretty much every epithelial tumor cell lines we have seen.'" Update: 02/15 17:27 GMT by KD : As reader CorporalKlinger pointed out, PPAR-gamma is a cellular receptor, not a compound; and this news is not particularly new.

Too Hot! wrote to mention a BBC article about extremely powerful synthetic muscles. From the article: "The most powerful type, 'shorted fuel cell muscles' convert chemical energy into heat, causing a special shape-memory metal alloy to contract. Turning down the heat allows the muscle to relax. Lab tests showed that these devices had a lifting strength more than 100 times that of normal skeletal muscle. Another kind of muscle being developed by the team converted chemical energy into electrical energy which caused a material made from carbon nanotube electrodes to bend."
