New Algorithm Could Substantially Speed Up MRI Scans 115

An anonymous reader writes "In a paper to be published in the journal Magnetic Resonance in Medicine, researchers detail an algorithm they have developed to dramatically speed up the process of producing MRI scans. The algorithm uses information gained from the first contrast scan to help it produce the subsequent images. In this way, the scanner does not have to start from scratch each time it produces a different image from the raw data, but already has a basic outline to work from, considerably shortening the time it takes to acquire each later scan."

Another quote about the generator, from the same page:

Probably the biggest opening for skeptics will be the continually running genset that is probably rated for 500 kW (my guess), and appears to have been connected by cables to the E-Cat. "Where's the mystery?" So knock yourselves out, skeptics. It's the customer who has to be happy, and apparently this one was satisfied that those cables were not contributing to the 470 kW output during self-sustaining mode.

This is the gold: (emphasis mine)

Power for start-up (resistive coils that provided heat to the reaction chambers) was provided by the large and loud genset (was making all the noise) you see that is nearly as large as the small shipping container in which the 1 MW E-Cat plant was arranged. Once the reaction chambers got up to temperature, they were maintained by the heat produced by the reaction. I'm not sure why they kept the generator running after that, but I would guess it was for back-up or safety. I'm sure the engineers testing the system made sure what the power levels were at all times.

I don't think I have to explain why I emphasized that part :-)

The funny thing about science is that you can do experiments to see who's right. You don't have to endlessly debate stuff.

GP states many experimental observations that directly contradict your hypotheses. Now you can whine about condescension, or man up and rethink them.

Law School Amplifies Critics Through SLAPP Suit 123

An anonymous reader writes "Michigan's Thomas M. Cooley Law School recently filed a lawsuit that appears to be boomeranging in the worst possible way. A little-noticed pseudonymous blogger respectfully disagreed with Cooley's self-awarded number-2 ranking, nationwide (well, perhaps not so respectfully), and had a few other choice things to say. So, Cooley went ahead and hired some lawyers (who had graduated from Georgetown and the University of Michigan) to file a lawsuit to unmask the blogger. And EFF cooperating attorney John Hermann got involved. "

This interactive pet rock might be useful for treatment of emotionally problematic people. People you wouldn't necessarily trust with a cat.

If the patient messes up with the robot, you can just reset its emotional state, and try again. A real pet could be dead or traumatized.
