holy_calamity writes "Two Cornell researchers have designed an open source 3D printer that costs just $2,400. The self-assembly kit is part of what they call the Fab@Home project — they hope it will spark development of rapid prototyping for the consumer market in the same way the Altair 8800 did for personal computing in seventies." Here is a video showing a completed machine constructing a silicone bulb (16-MB WMV).
Update: 01/10 04:02 GMT by KD : The developers of this kit are at Cornell, not Carnegie Mellon University as the original post erroneously stated.

paxmaniac writes "iRobot has announced Create: a new fully programmable mobile robot based on the Roomba robotic vacuum cleaner. People have been hacking the Roomba since the day it came out. Well, hacking just got a whole lot easier. A command module for the Create provides a programmable 8-bit Atmel micro controller, four DB-9 ports for your own sensors, and a number of sample programs that can be compiled and uploaded to the command module via USB. Botmag has more details and some cool applications. This looks like the perfect robotics platform for hobbyists, schools, and universities alike."

quixote9 tips us to a BBC story on a promising new cancer therapy using targeted nanoparticles. From the article: "The researchers used the nanoparticles to zero in on the network of blood vessels that supply the tumors in mice with nutrients and oxygen... [They] developed a technique for amplifying [the nanoparticles'] homing ability by designing a multifunctional nanoparticle that binds to a protein structure found only in tumors and associated blood vessels... The tests showed that within hours of the injection, the artificial platelets began blocking the supply without harming normal tissues. The scientists believe the nanoparticles could also be used to carry drugs to the tumor."

simoniker writes "In an opinion piece, casual game publisher WildTangent's CEO Alex St. John (himself a Microsoft veteran and one of the DirectX creators) has sharply criticized some of Windows Vista's features as they related to video game creation, noting: 'We have found many of the security changes planned for Vista alarming and likely to present sweeping challenges for PC gaming, especially for online distributed games. The central change that impacts all downloadable applications in Vista is the introduction of Limited User Accounts. LUA's can already be found in Windows XP, but nobody uses them because of the onerous restrictions they place on usability. In Vista, LUA's are mandatory and inescapable.'" Meanwhile, the word has also come down that games will be on the Zune by Summer of next year.

Ciarán Mooney writes to let us know that the Pledgebank drive to raise $10,000 for Project Nouvaeu is almost complete — at this moment it needs only 196 more people to sign up. Project Nouveau aims to provide open source 3D acceleration for nVidia cards. The drive was started by David Nielsen, whose blog explains what he hopes will happen.

An anonymous reader writes to mention a new, unique situation in Massively Multiplayer games. The Entropia Universe title has broken new ground by being granted five virtual banking licenses. These are exactly what you think they are: in-game bankers can transfer Entropia funds directly to your real-world bank account as real world cash. The well-known conversion rate between EU cash and real money allows this; more entertainingly, you can withdraw RL cash into EU notes via the banks as well. From the article: "These two-year exclusive licenses will be available through the public auction within Entropia Universe and will be open for bids beginning mid January 2007. Entropia Universe is the only virtual universe on the internet whose currency has a fixed exchange rate with the US Dollar. Its currency can easily be moved between Entropia Universe and the real world using an ATM card. The Entropia ATM card can be used to instantly withdraw real cash from over 1 million ATM machines worldwide"
