kreyszig writes "The recent story of a cat brain simulation from IBM had me wondering if this was really possible as described. Now a senior researcher in the same field has publicly denounced IBM's claims." More optimisticaly, dontmakemethink points out an "astounding article about new 'Neurogrid' computer chips which offer brain-like computing with extremely low power consumption. In a simulation of 55 million neurons on a traditional supercomputer, 320,000 watts of power was required, while a 1-million neuron Neurogrid chip array is expected to consume less than one watt."

mrcgran writes "Space.com is reporting a very deep hole found on Mars: 'The geological oddity measures some 330 feet (100 meters) across and is located on an otherwise bright dusty lava plain to the northeast of Arsia Mons, one of the four giant Tharsis volcanoes on the red planet. The Mars Reconnaissance Orbiter (MRO) used its High Resolution Imaging Science Experiment (HiRISE) instrument to draw a bead on the apparent deep hole — a feature that may cause more scientists to ponder about potential subsurface biology on Mars. Because the spot lacks a raised rim or tossed out material called ejecta, researchers have ruled out the pit being an impact crater. No walls or other details can be seen inside the hole, and so any possible walls might be perfectly vertical and extremely dark or — more likely — overhanging.' The original image and its cutout at full resolution can be found in the HiRISE site."

Fjan11 writes "Sun's Jonathan Schwartz has announced that Apple will be making ZFS 'the file system' in Mac OS 10.5 Leopard. It's possible that Leopard's Time Machine feature will require ZFS to run, because ZFS has back-up and snapshots build right in to the filesystem as well as a host of other features. 'Rumors of Apple's interest in ZFS began in April 2006, when an OpenSolaris mailing list revealed that Apple had contacted Sun regarding porting ZFS to OS 10. The file system later began making appearances in Leopard builds. ZFS has a long list of improvements over Apple's current file system, Journaled HFS+.'"

An anonymous reader writes "Following weeks of headlines touting strong sales for Blu-ray discs, rival next-gen format HD DVD looked like it had its own success story in the making with this week's HD DVD release of the cult hit 'Children of Men.' The disc recieved a stellar review at High-Def Digest, and went on to out-sell the most popular Blu-ray discs on Amazon. But now comes word of apparent incompatibility issues with the Xbox 360 HD DVD player, with some (but not all) consumers reporting that even multiple returns of the disc are unplayable on the format's leading playback device."

Several outlets are carrying the news that Live for Windows is coming in May to a PC near you. The announcement carried confirmation of a similar pricetag for Xbox Live, as well as details on some new titles. Halo 2 will be releasing right around the launch of the service (slated to go up May 8th), and Shadowrun will follow quickly sometime in June. Gamasutra has an interview with Xbox Live general manager JJ Richards on the subject, and 1up offers a bit of commentary with the news. Though when asked about it last week Microsoft reps seemed extremely confident, it still remains to be seen whether PC gamers will pay for what they've always gotten for free.

Megnatron writes "Penny Arcade has a letter from the stepmother of one of the kids who was recently charged with killing a homeless man. Her article is an extremely sobering tale of the problems dealing with troubled teen. She explains how, in this situation, the parents did everything they possibly could. And, in a refreshing twist, she absolves the games industry of any blame for the tragedy these kids perpetrated. From her missive: 'Video games DID NOT make this kid who he was, and it's unfortunate that the correlation is there. The thing that really gets me with this whole thing is that the kid knows full well that by equating what he's done to a video game, that he will generate controversy and media coverage. It makes me sick that the media is jumping all over this, because that is exactly the result that he wants. The only good thing (if there is such a thing) that has come out of this whole ordeal is that the kid is behind bars. That is exactly where he needs to be.'" Her letter is a passionate, troubling story, but well worth reading.

MattSparkes writes "The Mars rover Spirit used to get quite confused when it came upon a rock. Because it could only plan routes of a metre or two it couldn't understand how to navigate around large objects, and frequently used to rock back and forth for hours trying to figure it out. NASA have written new software called D* for the rover Opportunity, which should allow it to autonomously plan routes up to 50 metres long. The new software still won't be able to avoid sand-traps, though."
