E. coli copies 600 bases of DNA/second.
It makes one error every few billion bases, or one mutation per 1,000 generations.
I made an animation to show just how crazy this is. Every green square is a copied nucleotide. The red squares (very rare) are mutations. 🔻

Cable bacteria link together (thousands of cells, end-to-end) to conduct electrons across distances up to 7 centimeters. They are living batteries.
They were discovered in Aarhus, Denmark in 2012. I visited Aarhus last year to see them in person, and wrote about it today.

We made a huge poster that illustrates all of the major genome editing tools in one place.

The first experimentally-solved, 3D structures of the human sweetness receptor.
Resolved in complex with sucralose and aspartame; but the structures were identical. Upon binding, these molecules cause the protein to *slightly* bend & trigger a signaling cascade in the cell.
