Novel method to study quantum fluctuations in exotic phases of matter

We encounter phase transitions in our everyday lives when we witness water freezing or boiling. Similarly, quantum systems at a temperature of absolute zero also experience phase transitions. The pressure or magnetic field applied to such systems can be adjusted so that these systems arrive at a tipping point between two phases. At this point quantum fluctuations, rather than temperature fluctuations, drive these transitions.

Juno mission to Jupiter delivers first science results

NASA’s Juno mission is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released today. The Juno spacecraft has been in orbit around Jupiter since July 2016, passing within 3,000 miles of the equatorial cloudtops. …

Nanoalloys ten times as effective as pure platinum in fuel cells

A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars. Research results show that it is possible to significantly reduce the need for platinum, a precious and rare metal, by creating a nanoalloy using a new production technique. The technology is also well suited for mass production.

Just after the Big Bang: Galaxies created stars a hundred times faster now

A team of astronomers has discovered a new kind of galaxy which, although extremely old — formed less than a billion years after the Big Bang — creates stars more than a hundred times faster than our own Milky Way. …
