Protein Homology Network, data visualization by Alex Adai, Institute for Cellular and Molecular Biology – University of Texas, 2002
“The network summarizes the results of aprox. 92 billion pairwise amino acid sequence alignments between 289,069 proteins from 90 genomes. The final network is composed of 27,325 connected sets summing to 7,940,873 edges. An edge is colored blue if it connectes 2 proteins from the same species, and red if it connects 2 proteins from 2 different species. If that information is not available the edges are colored based on layout hierarchy.”

Caption: “Intercalation induces structural distortions. Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas).”
“In chemistry, intercalation is the reversible inclusion of a molecule (or group) between two other molecules (or groups). Examples include DNA intercalation and graphite intercalation compounds.”

I don’t know what to call this pattern, but I like it!

These images look like exotic phyto-plankton, but in fact they are boundary of different Julia sets. Julia sets are mathematical fractals. The same pattern repeats infinitely in smaller and smaller detail. Following the same simple rules repeatedly, these amazing patterns are formed.

Dude! That top one totally looks like a dendrimer! Will post more about dendrimers soon…
Bucky Ball Pendant by Shannon Henry (image source)
More info on buckminsterfullerene
Pendant from Polymath Design Lab, and similar ones are available at their Etsy store, although I don’t see this particular wooden version (or is it leather?).
They have other cool designs too!
Image 1: B-factor plot for 1AV1 truncated human apolipoprotein A-I
Caption: “B-factor plot of 1AV1, refined at 4 Å using the PMB B-factor patch for isotropic B-factor restraints. Note that even the side-chain b-factors are well-behaved, and that the molecular motions are modeled more accurately by these individual B-factors than they could be by a series of group B-factors.”
What is a B-factor plot? I don’t know, but these folks say: “Blue means helix, red means strand and green means turns and random coil.”

What is apolipoprotein A1? According to Wikipedia, it’s “the major protein component of high density lipoprotein (HDL) in plasma” i.e. the good cholesterol. It helps clear fats! Good job, apo A-I!
