Efficiency asymmetry: Scientists report fundamental asymmetry between heating and cooling

Erm. Did they found entropy?
Sorry, Im quite sceptical. I read the article, but still not sure what exactly they found, and why its a new finding.

"Our experimental device allows us to track the motion of the particle with exquisite precision, giving access to these previously unexplored dynamics," said Dr. Godec.

And...?

By manipulating the temperature and observing the resulting movements, the team gathered crucial data to understand the intricacies of heating and cooling at the microscale level.

And this data shows what? ...
