Insane in the membrane. Insane in the brain.


"Humanity is not sustainable. To maintain our lifestyle (yours and mine, basically) for the entire planet, you'd need five more Earths," biologist Paul R. Ehrlich told 60 Minutes in 2023. Ehrlich, who died Friday at 93, became a doomsday celebrity after his 1968 bestseller, “The Population Bomb,” warned of the collapse of nature. cbsn.ws/476tpB7

Richie Aprile’s death at the end of Season 2 of The Sopranos is still one of the most shocking things I’ve ever seen in television or film. This came out of absolutely nowhere & elevated my low opinion of Janice. This also changed the trajectory of the rest of the show.

This is a bacterial flagellar motor … one of nature’s most sophisticated molecular machines - a rotary motor embedded in the cell membrane consisting of ~25-30 protein types totaling 20,000-50,000 atoms in a multi-part structure of rotor, stator, drive shaft, and propeller. Operating at 100-300 Hz (6,000-18,000 RPM) with some species reaching 1,700 Hz (~100,000 RPM) at nearly 100% efficiency, this nanoscale engine features rotor proteins FliG/FliM/FliN forming the C-ring, MotA/MotB stator complexes, FlgG rod protein drive shaft, FliC flagellin propeller filament, and FlgE hook proteins acting as a universal joint, all powered by proton or sodium flow across the membrane generating torque through conformational changes in the stator complexes.
