The heated race to achieve the extreme cold that quantum technologies demand may have a frontrunner. Chinese scientists have ...

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 ...

Researchers working on advanced cooling systems have identified a class of rare-earth metallic alloys that could reduce the need for helium-3, a scarce isotope critical to both national security and ...

The closure of the Strait of Hormuz has trapped a third of the world’s commercial helium, threatening the irreplaceable ...

IT has been suggested that, for the explanation of the abnormal properties of liquid helium II, a division of the molecules into molecules ‘at rest’ and ‘moving’ ones is an essential feature 1,2,3.

White dwarf stars are glowing embers, the remains of small stars that have run out of fuel to burn Most white dwarfs are hot lumps of charcoal, gradually radiating their heat into space. But a few are ...
