Check out how @OttoLab got a beginning of Darwinian evolution with purely synthetic chemical systems!

And the last of 3 @OttoLab papers within 24h!

Biological principles are valid only for biological systems? Don't bet on that. We found synthetic replicators literally dying out when in competition, or coexisting if they have different food preferences.

@OttoLab gone wild 2/3
And one more system where foldamers interconvert with fibers, this time pH-controlled. Means in turn: light-controlled if you use a photoacid. Congrats to Yulong, @OttoLab and collaborators from Huc group in Munich!

You can do cool stuff even with monopeptides. My by-then colleague Ankush worked on one that forms first a foldamer, then a self-replicating fiber. In an out-of-equilibrium setup they can even coexist! Congrats to all authors :)
