MIT Group Creates a High-Temperature Superfluid

24.06.2005

Physicists at the Massachusetts Institute of Technology (MIT) have created the first example of a high-temperature superfluid: a new state of matter in which the atoms in a gas can move with no friction or slowing down whatsoever.

Reported in the June 23 issue of journal Nature, the work is closely related to the superconductivity of electrons in metals. According to Wolfgang Ketterle, the Nobel laureate who heads the MIT group, 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.

"In superfluids, as well as in superconductors, particles move in lockstep," explains Ketterle. "They form one big quantum-mechanical wave." Such a movement allows superconductors to carry electrical currents without resistance.



The MIT research was carried out at the MIT-Harvard Center for Ultracold Atoms, which is funded by the National Science Foundation (NSF), and received direct support from NSF, the Office of Naval Research, the National Aeronautics and Space Administration, and the Army Research Office.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
