This is a picture of. . .
A) the hair cells of the bat inner ear
B) a metals-polymer nanowire array
C) a previously unknown species of sea anemone
D) the cilia of the common goldfish parasite Trichodina
Answer below the fold!
If you answered polymer nanowires, you were right! This SEM by Rawiwan Laocharoensuk was the ACS NanoVision winning image for June 2008.

Claims by archpundit (apparently reflecting similar claims made in other places):
Lott claims his new survey will solve the problems, but that assumes he oversamples DGU's. If he doesn't, his finding will be as pointless as the…
Imagine that you are doing a physics lab to measure the velocity of a small projectile. After making a bunch of measurements to four significant figures, and doing a bunch of arithmetic, you get a value of 4.371928645 m/s. After yet more gruelling math, you find the uncertainty associated with this…
The NIDCD reported yesterday the discovery of a protein called protocadherin-15 (PC15)(which is associated with a form of genetic deafness called Usher Syndrome) as the likely player in the initial transduction of sound. As I have discussed here, the cochlea's sensory cells are called hair cells…
I think it's a metals-polymer nanowire array.
Woo-hoo! This is the second I've guessed right . . . although I don't feel as triumphant as I might if I actually knew what a metals polymer nanowire array is.
You stumped me on this one. I just knew I was glad I hadn't stumbled into it because to me it surely looked like something meant to ensnare and digest unwary prey.
