Up the magnetic pressure
Article Abstract:
The experimental observations of a phenomenon known as the magnetic fountain effect in superfluid helium could be used as a tool for studying many other exotic magnetic phenomena. The fountain effect occurs at temperatures above absolute zero when some fraction of the atoms is thermally excited into higher energy levels and as these atoms are not part of the condensate they form an ordinary, classical fluid component that has non-zero viscosity.

Pulsational pair instability as an explanation for the most luminous supernovae
Article Abstract:
The article explains the formation of the most luminous supernovae by a huge explosion of various unstable pairs of stars. The analysis reveals that the pair instability leads to explosive burning and radiates large amount of light.

Shear madness
Article Abstract:
The odd behavior of solid helium on being cooled to temperatures just above absolute zero is discussed. The behavior is found to be a result of the various imperfections of the crystal, which change the properties of the atom.
