(PhysOrg.com) -- A renowned expert on helium says we are wasting our supplies of the inert gas helium and will run out within 25 to 30 years, which will have disastrous consequences for hospitals and industry.
A trio of researchers at Columbia University has found more evidence showing that sound waves carry mass. In their paper published in the journal Physical Review Letters, Angelo Esposito, Rafael Krichevsky and Alberto Nicolis ...
Physicists from Lancaster University have established why objects moving through superfluid helium-3 lack a speed limit in a continuation of earlier Lancaster research.

Ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. Now physicists have theoretically shown that in one-dimensional ...
A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories.

(PhysOrg.com) -- Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime example of how ...
For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object, originally foreseen by cosmology theorists, may help explaining ...
