Grant & I have something of an ongoing friendly competition to come up with stunning & unusual biological images. Here, via PZ (as usual!) & The Node is my latest offering:

It’s a confocal microscope image of a squid embryo. The reddish areas are neural tissue (mmmm, braaaainzz) & each of those fluorescent green speckles is a tuft of cilia. (I wouldn’t have known that stuff but Sven DiMilo, one of PZ’s ‘regulars’, kindly explained it.)

Just lovely :-)

Your turn, Grant!
