Modeling Supernovae With a Supercomputer
Categories: Science
A team of scientists at the University of Chicago will be using 22 million processor-hours to simulate the physics of exploding stars. The team will make use of the Blue Gene/P supercomputer at Argonne National Laboratory to analyze four different scenarios for type Ia supernovae. Included in the link is a video simulation of a thermonuclear flame busting its way out of a white dwarf. The processing time was made possible by the Department of Energy’s INCITE program. “Burning in a white dwarf can occur as a deflagration or as a detonation. ‘Imagine a pool of gasoline and throw a match on it. That kind of burning across the pool of gasoline is a deflagration,’ Jordan said. ‘A detonation is …

Ant contributes a link spotted on Neatorama that may upset middle school Earth Science teachers, writing “LiveScience says Earth’s simple schematic is not core, mantle, and crust anymore. It is more like the gooey center of a chocolate morsel harboring peanut butter and honey. Inner Earth is far more nuanced than outward appearances would suggest. A new model is proposed in the May 2, 2008, issue of the journal Science.”Read more of this story at Slashdot.

Read MoreBringing Surgical Robots Into the Mainsteam
Categories: Science
The New York Times is running a story about how using robots to perform surgical operations has been transformed from a controversial dream to reality. Dr. Frederic Moll abandoned his residency for Silicon Valley and helped to revolutionize the industry. The lengthy article also discusses some of his innovations. We’ve discussed various robot-assisted medical procedures in the past. From the Times: “‘I was struck by the size of the incision and injury created just to get inside the body,’ Dr. Moll says. ‘It felt antiquated.’ He took the idea to his employer, Guidant, a medical device company. Guidant decided that robotic surgery was too futuristic and too risky, so Dr. Moll rounded up backers, resigned, and in 1995, founded Intuitive …
