As you probably know, my specialty are birds, so writing this series on clocks in microorganisms was quite an eye-opener for me and I have learned a lot. The previous two posts cover the clocks in the ...

A Japanese research team has studied ancient timekeeping systems to better understand the circadian clock in modern cyanobacteria. The researchers compared the functions of ancestral Kai proteins with ...

Precision timekeeping has been rapidly evolving from astronomical observations in ancient times to mechanical clocks to quartz to present-day quantum atomic clocks, becoming a critical requirement in ...

Evolution is often thought of as a process that takes millions of years, but that's not always the case. Single-celled organisms, in particular, ride an evolutionary fast track. Within weeks, a ...
