AI spots heart risk in routine ECGs

AI's ability to find hidden patterns in medical data takes a practical turn today, with a model that spots sudden cardiac death risk from a standard ECG. Meanwhile, the line between real and fake faces blurs further, and a Stanford study makes the case against daylight saving time on health grounds.

AI may spot deadly heart risk in a routine ECG

The AI model picks up on subtle ECG patterns that doctors miss, which could make sudden cardiac death screening as routine as an EKG. The real impact would be catching younger athletes and people without known heart problems.

Perception and time

Two stories question how we perceive reality: AI faces have become so realistic they fool most people, and physicists explore whether time might flow in reverse.

People can learn to spot AI faces – but the clues are no longer obvious

AI faces have crossed into 'hyperreal' territory where they look more real than actual human faces. The piece offers practical tips for spotting them, but the key takeaway is that overconfidence makes people worse at detection.

Time May Flow in Reverse—And Control the Universe Across Multiple Dimensions, Theories Claim

This is a speculative but fascinating dive into whether time is fundamental or emergent, touching on tachyons and multiple dimensions. Not a new study, but a well-written overview of fringe ideas that challenge causality.

Health and environment

A Stanford study adds to the case against daylight saving time, linking it to long-term health harms from circadian disruption.

Study suggests most Americans would be healthier without daylight saving time

The Stanford study goes beyond the usual 'spring forward is bad' argument, showing that year-round daylight saving time itself may be harmful by chronically disrupting circadian rhythms. The researchers advocate for permanent standard time.
