Turning water into ice in the quantum realm (Update)

When you pop a tray of water into the freezer, you get ice cubes. Now, researchers from the University of Colorado Boulder and the University of Toronto have achieved a similar transition using clouds of ultracold atoms.

Quantum computing advance locates neutral atoms

For any computer, being able to manipulate information is essential, but for quantum computing, singling out one data location without influencing any of the surrounding locations is difficult. Now, a team of Penn State physicists ...

Giant hydrogen cloud spotted around the Triangulum Galaxy

(Phys.org)—While peering into the nearby Triangulum Galaxy known as M33, astronomers have detected what appears to be a giant cloud of hydrogen around it. According to research published online on May 5 on the arXiv pre-print ...

Carbon 'budget' may be bigger than thought: study

An ambitious goal to limit global warming to 1.5 degrees Celsius is still within reach, said researchers Monday who calculated humanity may have a larger allowable "budget" for burning carbon than previously thought.

Recalculating the distance to interstellar space

(PhysOrg.com) -- Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously ...

Six-fold jump in polar ice loss lifts global oceans

Greenland and Antarctica are shedding six times more ice than during the 1990s, driving sea level rise that could see annual flooding by 2100 in regions home today to some 400 million people, scientists have warned.
