I hate to follow the pattern of negative Hacker News comments, but this article is atrocious. Please don't upvote it.
First, the title is total clickbait. Heat and sound are magnetic??? More like heat and sound are affected a little bit by magnetic fields. (Giant magnetic fields at low temperature, no less.)
Second, take a look at the first paragraph:
>"Earlier this month, we reported on research demonstrating that heat propagates as a wave through graphene rather than as vibrations of atoms the way it does in 3-D materials. In 3-D materials, the collective state of those vibrating atoms is known as phonons."
What does it mean to say that heat propagates as a wave rather than as vibrations of atoms? The definition of phonon is a WAVE of ATOMIC VIBRATIONS. It makes zero sense to say it travels as wave, but not as vibrations. Also, there is not a fundamental difference between heat transport in graphene and normal materials - the main difference is that is just takes a longer distance before the wavelike motion scatters enough to become diffusive.

Having been taught by both Roberto Myers and Dr. Heremans, they wouldn't release something like this unless they had repeatedly reproduced results and were extremely confident in their findings.
