Researchers found a scenario where things get more organized on their own, which basically breaks the laws of physics.

The Takeaway
The Second Law is the ultimate "rule" of the universe, stating that entropy (disorder) always increases over time. This paper uses a specific setup involving heat and electricity to argue that you can actually force a system to become more ordered, potentially finding a loophole in one of the most bedrock laws of physics.
From the abstract
This paper is accountable only to explicitly stated physical assumptions and strict logical inference. Its goal is to run a rigorous stress test of second-law claims within the Clausius framework. We work directly with \textbf{Clausius's entropy definition} for an isolated composite with energy-form conversion. Heat is withdrawn from a cold releasing subsystem with relatively small heat capacity, converted to electrical energy, and then delivered as heat to a hotter subsystem. In the ideal limit
