Simulating the Universe with a zBox
An anonymous reader writes "Scientists at the University of Zurich predict that our galaxy is filled with a quadrillion clouds of dark matter with the mass of the Earth and size of the solar system. The results in this weeks journal Nature, also covered in Astronomy magazine, were made using a six month calculation on hundreds of processors of a self-built supercomputer, the zBox. This novel machine is a high density cube of processors cooled by a central airflow system. I like the initial back of an envelope design. Apparently, one of these ghostly dark matter haloes passes through the solar system every few thousand years leaving a trail of high energy gamma ray photons." -

The Internet Meets the Neural Net
orangesquid writes "OpenEEG is a system for getting data from your brain to your computer. Recently, work was resumed on scEEG, a soundcard-based system which may one day make home EEG systems very cheap (they currently cost a few hundred US$ to put together; there are, though, some potential cheaper alternatives). But, what research is being done into getting data from your computer to your brain? There have been some systems that inject optical signals into your eyes, but, what about direct neural interfacing? It seems EMF and light are one option; playing with neurotransmitters may be another. What do /.'ers foresee coming in this field? What research have you seen being done? Particularly, is any of this to the point where homemade, low-cost systems are feasible? Where can I find out how to inject signals into my head? Combining this with openEEG might lead to some exciting new levels of Internet addiction." -
Open Solutions For EEG, Biofeedback Hardware?
peko asks: "Does anyone have some experience with free/open solutions for eeg/biofeedback gizmos - especially for the PC. I dream about low cost solution for something like: Procomp & Biograph, Bionetica, Neuroscan, Loreta, and ThoughtForm. " -
Neuroscience meets Robotics
Neuromorph writes "In Telluride, at the The Telluride 1999 NSF Workshop on Neuromorphic Engineering, in the middle of the Rockies, 50 neuromorphic engineers from across the world will spend the next few weeks developing ground-breaking neurologically inspired technology. The projects include silicon aVLSI retinas and cochleas, autonomous flying blimps, robotic legs and hands, electronic cortical models and synthetic epistemology. " Alright. Someone's gonna have to inflitrate and get pictures and updates-send over my way.
