[:es]To Be Energy-Efficient, Brains Predict Their Perceptions[:]
Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.

[:es]A New Theory for Systems That Defy Newton’s Third Law[:]
In nonreciprocal systems, where Newton’s third law falls apart, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena.
