Science Daily reports that researchers have conducted the first detailed analysis of deaths during expeditions to the summit of Mt. Everest. They found that most deaths occur during descents from the summit in the so-called "death zone" above 8,000 meters, and also identified factors that appear to be associated with a greater risk of death, particularly symptoms of high-altitude cerebral edema. The big surprise that the data indicate those deaths aren't primarily from avalanches or falling ice, as had long been believed.

MTV's Multiplayer Blog reports on recent announcements from Activision Blizzard which confirm that sequels to several popular franchises are on the way. The games include a new Guitar Hero, Call of Duty: Modern Warfare 2, and a new Tony Hawk, which will use some kind of non-standard controller. "At the meeting, Activision Blizzard showcased new games that would make sense for in-game ads, including the vaguely titled "Guitar Hero 5," which included a screen shot of gameplay with a Burger King ad to the right of the note highway."

Epic Games president Michael Capps did an interview recently with GamesIndustry, and he had some interesting things to say about the future of downloadable content, and how it will affect the retail games market. He also discussed the trend toward social gaming, and Epic's plans in that regard.

Our primary retailer makes the majority of its money off of secondary sales, and so you're starting to see games taking proactive steps toward that by ... if you buy the retail version you get the unlock code. I've talked to some developers who are saying 'If you want to fight the final boss you go online and pay USD 20, but if you bought the retail version you got it for free.' We don't make any money when someone rents it, and we don't make any money when someone buys it used — way more than twice as many people played Gears than bought it."
