A new experiment reports pair formation when a gas of ultracold potassium-40 atoms is in the largely unexplored region of strong interactions.

Vocal-tract resonances enhance the output of the vocal cords. They also create the distinctions between different vowels sounds. For sopranos singing high notes, the two functions come into conflict.

Previously intractable systems are now within the modeler’s grasp, thanks to an approach adapted from the study of lattice spin systems.

The Hubble Space Telescope has been sentenced to a slow death as NASA worries about minimizing risks to astronauts, completing the space station, and sending people to Mars. Astronomers are fighting a last-ditch campaign to reverse NASA’s HST decision.

NSF created a major research equipment and facilities construction account in 1995 to better manage large scientific facilities, but that hasn’t quelled concerns about both the selection process and ongoing oversight of such projects.

Both the precision control of trapped-ion systems and very large samples of cold neutral atoms are opening important new possibilities for quantum computation and simulation.

Quantum gravity may force theoretical physicists to rethink one of the great conundrums in modern physics.

Materials with correlated electrons exhibit some of the most intriguing phenomena in condensed matter physics. A new theoretical framework is now allowing theorists to calculate the electronic structure of these materials, which can exist in a rich variety of phases.
