A team of physicists from France have discovered a simple organic substance, made out of two compounds, that turns solid when heated and back to liquid upon cooling. (figure 1)
Usually, a solid substance would melt, thus becoming liquid, when confronted with heat, or turn to gas, if it was in a liquid state. Some exceptions have been studied, especially when the heating process would cause something like polymerisation. But no case had ever been discovered of a reversible transition involving liquid turning to solid when heated.
The team of Grenoble-based scientists have attributed this peculiar transformation to the hydrogen bonds.

Wow, how about this for an original finding? Very interesting...
