...clusion is consistent with the 2004 discovery of a cooling
white dwarf star that appears to have a solid diamond core 4000 kilometers across. Although diamond formation in the atmospheres of gas giants is not strictly impossible, the Dutch physicists say that the odds are exceedingly slim that a diamond c...

Menthol receptor also important in detecting cold temperatures
..., cultured nerve cells that express TRPM8 react to cooling
stimuli, but cells cultured from mice lacking TRPM8 do not. Also, mice engineered without TRPM8 are much less sensitive to cold than mice with TRPM8. TRPM8 does not seem to be the sole receptor responsible for detecting cold, Jordt said. The TRPM8...
