It's the really big one.
For the grand finale.
Thanks so much for stopping by everybody.
And have a great and fantastic holiday season, no matter how you celebrate it.
Tree ornament image at the top of the post?....It's actually a little hollow ball of cells about a 100 microns across that is suspended in some super-special goopey stuff... The tiny blue ovals are the nuclei of individual cells...The green line between neighbouring cells is the molecular velcro that holds everything together...The red line is a super-slippery bit of molecular teflon that helps inflate the inner hollow part of the ball...Image taken by a former gradual student who is now a much better teacher than I will ever be.
