This article has some startling and interesting implications for physics.

Slowed light to 38 mph... and then stopped it...

so that might eventually lead to supercomputers that can be worn like wristwatches?

Interesting, but the articled doesn't really explain much. You can't really completely stop anything--let alone light--and they're not clear whether they're actually slowing or the gas cloud just has an extremely variable index of refraction.

Light will travel at different rates through different medium... even if it is just a high refractive index, it is still changing the speed of the light entering it.
