Why does insomnia therapy work wonders for some but not for others?
In shift-working firefighters, we found 3 distinct response patterns—and the reasons behind them.
Mathematics helped us uncover the hidden factors.

Reconstituting the cyanobacterial clock in synthetic cells shows:
1. High Kai protein levels keep rhythms running
2. SasA & CikA “buffer” against protein fluctuations
3. TTFL keeps phases synchronized
The 3-part recipe for precision timekeeping.

Reconstitution of circadian clock in synthetic cells reveals principles of timekeeping - Nature Communications
The remarkable fidelity of the cyanobacterial clock is poorly understood. Here, the authors reconstitute the clock in cell-like vesicles and reveal that high protein concentrations, associated regulat...
