CiteSeerX — An Evolved Circuit, Intrinsic in Silicon, Entwined with Physics
This had a circuit that was temperature sensitive, but it optimized better than human and it used a cell not connected to the circuit that could not be removed without altering the output (likely evolved to use crosstalk beneficially)

The genomic landscape of rapid repeated evolutionary adaptation to toxic polluti...
Apparently the Atlantic Killifish has some sort of rapid evolution gene quirk, which has allowed it to adapt quickly to human polluted waters fast.

Getting to “Yes” for Corporate Innovation | Steve Blank on
This is pretty good advice actually, but need a C-level innovation leader (CiO) to back it or it has no legs.

Emergence of Polymorphic Mating Strategies in Robot Colonies
Interesting use of robot stand-ins ("cyber rodents") for evolutionary biology simulation to see emergent behavior. Though they did use hermaphroditic robots this time around...

20120816_hydrodynamics_portuguese-man-o-war_Iosilevskii-613-26.pdf (application/pdf Object)
Interesting paper covering the hydrodynamics of a Man-of-War, which seems optimized to sail using the wind at specific water surface speeds to optimize the spread of its tentacles for prey capture.

Download Graphic Images from the Hillis/Bull Lab
Interest visualization of genetic similarity from a small selection of species, graphed in hierarchical order of sorts, similar to the Tree of Life. Apparently, to be human legible, you need a piece of paper over 1 square meter to print out on.

A Perovskite Oxide Optimized for Oxygen Evolution Catalysis from Molecular Orbital Principles
So getting oxygen out of water by electrolysis has traditionally been the limiting factor in performance. This new catalyst is apparently an order of magnitude better than the previous catalyst, but suffers from the same limitation, namely requiring an alkaline solution media to perform at its best. So perhaps not quite ready for primetime. However, apparently there are some integration possibilities with Dr. Nocera's artificial leaf project, which uses similar behavior catalysts.

Consecutive Thermal H2 and Light-Induced O2 Evolution from Water Promoted by a Metal Complex -- Kohl et al. 324 (5923): 74 -- Science
Okay, if this pans out, this could be huge. An artificial photosynthesis engine to produce hydrogen and oxygen, via a ruthenium metal complex. It's not clear if the hydrogen and oxygen liberation steps must be distinct. Could do a vertical torus pressure vessel half filled with cool water and a rotating catalyst bed ring, moving through pressure seals to separate the upper and lower halfs of the torus. Blast a quarter ring of the exposed exposed upper catalyst with hot water/steam to get a mixed steam/H2 stream, then blast the the other exposed quarter with the light to get O2, that by simple condensation of the stream will yield your hydrogen and oxygen. Dip the catalyst ring back into the cool water to regenerate the catalyst. I suppose there might be some chamber partitioning tricks to keep the oxygen and hydrogen separate.
