This is a further article demonstrating that information is physical. It is nice to be getting some empirical results.

The previous article, which I mentioned on this list, is Toyabe, S., Sagawa, T., Ueda, M., Muneyuki, E. & Sano, M. Nature Phys. 6, 988992 (2010). It demonstrated that information could be converted to energy, which I consider a no brainer on first principles, but many people have been sceptical.
The new article is Bérut, A. et al. Nature 483, 187189 (2012).
