Weaire–Phelan structure

“Nice animation of the weaire–phelan structure. Although: there are only two shapes. The black shapes are the irregular dodecahedron and the red, blue and green are all the same tetrakaidecahedron (dodecahedron with two extra hexagon faces).”

Kinesins

“Kinesins are motor proteins that move molecules around the cell. They are powered by ATP and transport molecules along microtube filaments at a rate of 2000 nm/s, meaning they take 250 tiny steps a second.”
