MIT physicists create new form of matter

No, not Islamic scientists this time, either:

MIT physicists create new form of matter

MIT scientists have brought a supercool end to a heated race among physicists: They have become the first to create a new type of matter, a gas of atoms that shows high-temperature superfluidity. Their work is closely related to the superconductivity of electrons in metals. Observations of superfluids may help solve lingering questions about high-temperature superconductivity, which has widespread applications for magnets, sensors and energy-efficient transport of electricity, said Wolfgang Ketterle, a Nobel laureate who heads the MIT group. Seeing the superfluid gas so clearly is such a dramatic step that Dan Kleppner, director of the MIT-Harvard Center for Ultracold Atoms, said, "This is not a smoking gun for superfluidity. This is a cannon.""In superfluids, as well as in superconductors, particles move in lockstep. They form one big quantum-mechanical wave," explained Ketterle. Such a movement allows superconductors to carry electrical currents without resistance. The work is based on the MIT group's earlier creation of Bose-Einstein condensates, a form of matter in which particles condense and act as one big wave. Albert Einstein predicted this phenomenon in 1925. Scientists later realized that Bose-Einstein condensation and superfluidity are intimately related.

Here's Ulf again

Good for Ulf! Maybe his actions will awaken some slumbering Swedes. Maybe even the comatose ones too!

The problem with 'slumering swedes' is that they dont have media coverage of the events going on...

You need critical coverage.

also, the muzzies are consentrated in specific areas, not all spread out (yet)..... so it may not affect they dont experience it..
