'Squeezed' quantum vacuum filled with atoms Posted: 02 Dec 2011 12:52 PM PST Quantum theory is known for its peculiar concepts that appear to contradict the fundamental principles of traditional physics. Researchers have now succeeded in creating a special quantum state between two mesoscopic gases with approximately 500 atoms. The state is known as a "squeezed" vacuum, in which measuring one gas affects the results of the measurement on the other. To produce these results the team had to develop a novel detection technique to measure values in atomic gases that were previously unobtainable.

In the dragonfish's mouth: The next generation of superstars to stir up our galaxy Posted: 02 Dec 2011 06:10 AM PST Astronomers have found the most numerous batch of young, supermassive stars yet observed in our galaxy: hundreds of thousands of stars, including several hundreds of the most massive kind -blue stars dozens of times heavier than our Sun. The light these newborn stars emit is so intense it has pushed out and heated the gas that gave them birth, carving out a glowing hollow shell about a hundred light-years across.
