Media Algorithms Keep You in a Bubble

Engagement algorithms are simple. If you, the user, have engaged with a certain topic in the past, you are likely to engage in the future.

This selection for engagement places you, the user, in an engagement maxima. You are maximally engaged given the topics you have expressed interest in in the past. But what happens after a f...

 An Algorithm for Predicting Longevity

For the test, participants exercised on a treadmill at increasing speed and incline. While they were exercising, the researches measured peak heart rate (%MPHR) and their ability to withstand physical exertion. On that latter point, they measured metabolic equivalents, or METs, which gauges how much energy the body expends during exercise. The more intense the exercise, the higher the METs (e.g. slow walking = ~2 METs, whereas running = ~8 METs). [...] FIT Treadmill Score = %MPHR 12(M...
