I recently mentioned a study reporting circadian oscillations of bacterial clock-proteins KaiA, KaiB and KaiC in a dish with no transcription and translation whatsoever - the oscillations being due entirely to polymerization of proteins. Now, a mathematical model of this system has also been published describing how the working of the system is possible.

In the new issue of Seed, Douglas Hofstadter talks about "strange loops" - his term for patterns of level-crossing feedback inside some medium (such as neurons) - and their role in consciousness.
Two very interesting papers this week:
The Circadian Clock in Arabidopsis Roots Is a Simplified Slave Version of the Clock in Shoots:
Transverse or longitudinal waves, purely as a matter of aesthetic preference? Transverse all the way, of course.
I'm fully immersed in writing a big grant proposal so I have even less time for blogging and reading blogs than usual, but that doesn't mean I have no time.
