Your phone can use tiny skin-color changes to measure your heart rate, measuring your face when you unlock it. good to within 5 beats per minute. it also estimates its confidence of each measurement, and throws them away when too low. impressive, and a bit scary what you can measure with neural nets.

good discussion in the podcast: https://www.nature.com/articles/d41586-026-01793-1
