Fine-tuning a neural network is like trying to alter a black hole without touching its event horizon: you change only a tiny fraction of parameters. Researchers looked inside and saw stunning patterns — strong links between pieces of the model, akin to quantum entanglement.

A modern hospital sensor is like a sensitive microphone in a noisy hall. It picks up a weak signal from the heart or brain, but along with it comes the hum of machines, footsteps, the breathing of neighbors. Separating the desired sound from the interference is a science in itself.
