Star Trek Medicine
What I want from doctors is Star Trek medicine--diagnosis and cure with no bodily invasion. Mark Anderson of Wired.com reports that tricorders are getting closer to reality, citing a number of different, largely unrelated, developments, including this mind-blowing one:
In the other research, scientists have developed a compact, precision-magnetic microscope based on a new state of matter. The technology, the researchers said, is as effective as current imaging devices such as MEGs for the brain and MCGs for the heart, which require a hospital visit because the devices are large and expensive.
It's made possible by a state of matter discovered just 12 years ago called the Bose-Einstein condensate.
Physicists at UC Berkeley have developed the device by harnessing a special property of Bose-Einstein condensates: Because they are cooled close to absolute zero, they are as free of vibrations and thermal noise as a quantum system can be, and are thus like a quiet, acoustically pristine concert hall. Tiny magnetic fields that might be unobservable in other systems are easily picked up.
Dan Stamper-Kurn, assistant professor of physics at Berkeley, and his colleagues published the work in the May 18 issue of Physical Review Letters. Unlike the superconductors that power current magnetic imaging, Stamper-Kurn's device is cooled not by gigantic refrigerators but by lasers -- making the prospect for miniaturization bright.
"I don't know when will come the day that you can strap a Bose-Einstein condensation experiment to your head," Stamper-Kurn said. But, he added, both the lasers and the vacuum chambers needed to make a condensate are shrinking fast.
