Ars Technica notes, from Nintendo's Fall conference earlier this week, the news that Mario Kart for the Wii is slated for Spring of next year. The game is said to involve bikes for the first time: "It is unclear whether the bikes will be mostly an aesthetic effect or if the control mechanics will differ between karts and bikes. Mario Kart: Double Dash featured a collection of different carts with different statistics, but control was more or less the same across the board ... Despite accusations that Nintendo had nothing to offer the hardcore gamer in terms of announcements at the show, the latest incarnation of the classic kart-racing series was looking sharp in its debut."

BobB writes "St. Louis University researchers have concocted batteries fueled by almost any kind of sugar, from tree sap to flat soda, and that could be used to power everything from computers to cell phones. Their thinking: If sugar can jack up the human body, why not electronics?"

Zoolander writes "Christopher Tolkien has completed the last book of J.R.R. Tolkien from notes left from his father." The ultimate question is how much of a quality difference will there be; for instance the difference between Dune and Dune: House Atriedes is a pretty big gap. But in my experience, Christopher Tolkien has always taken a good, cautious approach when it comes to his father's work so here's to hoping.

superdan2k writes "When Nintendo brought the Wii to market, one of their stated goals was to get people who didn't normally play video games using their console. Based on an article from the AP, it seems they've made some headway in capturing the senior citizen market. With the Wii's price point, and it being a good way to get people engaged in physical exercise, it's easy to envision it catching on with other retirement homes beyond the one mentioned in the article."

Several readers wrote in about AMD's entry into the 65-nm manufacturing generation. The company introduced four chips to be manufactured with 65-nm process in the first quarter of 2007 to replace existing 90-nm chips in their lineup. AMD is playing up the power economy of its line, claiming that even its existing 90-nm parts consume less than 50% the power of Intel's Core 2 Duo, averaged over a typical day's usage, while the new 65-nm chips will be even stingier with power. Next stop, 45-nm. The article says that AMD has a goal of catching up within 18 months to Intel's lead on the way to 45-nm technology.

ScentCone writes "North Korea says that it has conducted its first nuclear weapons test and 'brought happiness to its people.' Japan and China earlier issued an unusual joint statement saying that such a test would be 'unacceptable.' As of 11:10PM EST, the USGS says that it has not detected any unusual seismic activity on the Korean peninsula in the last 48 hours." From the article: "The North said last week it would conduct a test, sparking regional concern and frantic diplomatic efforts aimed at dissuading Pyongyang from such a move. North Korea has long claimed to have nuclear weapons, but had never before performed a known test to prove its arsenal. The nuclear test was conducted at 10:36 a.m. (0136 GMT) in Hwaderi near Kilju city, Yonhap reported, citing defense officials." Update: 10/09 05:50 GMT by J : The U.S. Geological Survey reports a 4.2 magnitude quake; South Korean news is reporting a 3.58 magnitude event; the White House apparently confirms a nuclear test.

The Nintendo conference seemed to be the perfect opposite of Sony's conference yesterday. It was polished, the presenters were poised, and the demos conveyed exactly the message they were aiming for. Notable info includes 27 playable Wii titles on the E3 floor, a speaker in the Wii controller, a StarFox title for the DS, and a confirmation of motion sensor in the nunchuck attachment. There will be two versions of Twilight Princess (one for Wii, one for GC) and they'll both be out on Wii launch day. Launch is slated for Q4 of this year. The presenters kept the launch price and date under wraps as the tone of the event was inspiration, not information. The number of playable games available this week confirms their commitment to a launch date this year, and the hilarious tennis game played onstage by the Nintendo honchos and the contest winner made their 'playing = believing' slogan really hit home. More flash than substance, but a solid presentation overall

Sony's conference offered up reassurance that a number of their titles will be playable at this year's E3. The controller will sense movement, allowing the player to move an onscreen avatar 'naturally'. They also released the system's launch details. The North American PS3 launch will occur on Nov. 17th, 2006. The 20GB HDD version will retail for $499, and the 60GB HDD version will go for $599. They promise 4 million launch units by December 31st. Update: 05/09 03:57 GMT by Z : Apparently, not only does the $499 system have a smaller harddrive, but it has fewer features as well.

An anonymous reader writes "ITO is running a comprehensive article on VoIP security issues and how one can protect against them: "VoIP creates new ways of delivering fully-featured phone services that promise big cost savings and open the way for a whole new range of multimedia communication services. After years of 'will it, won't it' speculation and unfulfilled predictions of universal adoption, Gartner is now positioning VoIP firmly on its way to the 'plateau of productivity' on its widely-respected technology hype cycle. But questions about its security and reliability persist.""

EA today confirmed the existence of a much-anticipated next-gen title, Army of Two. From the Eurogamer article: "Army of Two 'will throw gamers into hot spots ripped from current day headlines,' says EA, where they will use two-man strategies and tactics, transitioning between playing with an AI partner or a live player. We're told that EA's wanted to make this for ages, but until now it's felt that the hardware couldn't deliver a suitably believable co-operative AI player."
