Scientists Built a Cell, a Heart, and a Mini-Universe This Week
From a synthetic 'SpudCell' that eats and divides to a soft robotic heart that mimics human failure, and a lab-grown mini-universe where time itself emerges — here's what the past week revealed about building life, health, and cosmic reality from scratch.
The Signal
This week, three separate research teams showed that the boundary between "natural" and "built" is getting thinner by the day. A physicist in Birmingham created a miniature universe from a cloud of ultracold atoms and watched time emerge from inside it. A separate team unveiled a synthetic cell nicknamed SpudCell that can feed, grow, and divide like the real thing. And engineers built a soft robotic heart that can mimic one of the most common and mysterious forms of heart failure....
