In all of physical law, there’s arguably no principle more sacrosanct than the second law of thermodynamics — the notion that entropy, a measure of disorder, will always stay the same or increase. “If someone […]

If you’ve interacted with another human being this year, you’ve probably heard of Wordle, the addictive word-guessing game the coder Josh Wardle created for his partner and then sold to The New York Times for […]

The idea that life’s deepest, oldest roots were laid down by RNA molecules that evolved ever more complexity has dominated the origins-of-life field for the past few decades, reigning over competing theories that started instead […]
