University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation ...

If you take helium gas and you cool it at atmospheric pressure to 4.2 K it becomes a liquid. Keep cooling to 2.2 K and the helium enters its superfluid phase, called helium II. Superfluid helium has ...

In 2004 researchers reported the first clear evidence for superfluidity in solid helium-4. However, Matthew Chalmers describes recent experimental and theoretical work that has brought the very ...

Talk about passing gas: Vast stores of helium are escaping from the steam vents and hot springs of Yellowstone National Park after being trapped within Earth’s crust for up to 2 billion years, ...

The long-held, but unproven idea that helium-4 enters into an exotic phase of matter dubbed a "supersolid" when cooled to extremely low temperatures has been challenged in a new article. The long-held ...

The Company is pleased to announce the spudding of the Jackson-4 development well at its Galactica helium project in Las Animas County, Colorado. The shallow ...
