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.

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 Wnt genes produce signalling proteins that play important roles in early development, regulating cell proliferation, differentiation and migration. It's hugely important, used in everything from early axis specification in the embryo to fine-tuning axon pathfinding in the nervous system. The…

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.
