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 …

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 …

A Yale University doctor who analyzed images of Akhenaten for an annual conference at the University of Maryland School of Medicine has concluded that Akhenaten's female form was due to a genetic mutation that caused his body to convert more male hormones to female hormones than needed. (AP Photo/Matt Rourke)AP - Akhenaten wasn’t the most manly pharaoh, even though he fathered at least a half-dozen children. In fact, his form was quite feminine, which has puzzled experts for years.
