A dying star was already shedding its outer layers and fading toward white dwarfhood—then, 30 years ago, a sudden helium flash hit the brakes, reigniting it and dramatically reshaping its brightness and structure. Anton Petrov unpacks how Sakurai's Object pulled off this rare stellar reversal and what it teaches us about the messy final acts of stars.
Researchers implanted human neurons into mouse brains, watching them wire themselves into the host circuitry and develop distinctly human characteristics along the way.
