Scientists create glowing artificial cells that pulse to 24-hour biological clock

SMRTR summary

Scientists at UC Merced created artificial cells that glow and pulse with a 24-hour rhythm, mimicking natural circadian rhythms. The breakthrough reveals how biological clocks maintain stability in noisy cellular environments. The team's findings suggest that higher concentrations of clock proteins improve timekeeping reliability, potentially leading to applications in drug delivery and biological machines.
