In new research, scientists at the Department of Energy’s SLAC National Accelerator Laboratory used the Stanford-SLAC Cryo-EM Center to capture, for the first time, the formation of an immune signaling complex inside intact human cells. The team used cryo-electron tomography, a technique that allows researchers to generate 3D reconstructions of cellular structures preserved in a frozen state. The method makes it possible to observe molecular assemblies inside cells at extremely high resolution.

Ahab hunting down Moby Dick. Wile E. Coyote chasing the Road Runner. Learning Latin. Walking over hot coals. Standing in a long line for boba tea or entrance to a small, overpriced clothing retail store. Forking up for luxury nonsense. What do these activities have in common?

This has been shown in animals across the animal kingdom.” Blame dopamine: the “do it again, do it some more” brain chemical that’s been much talked about in connection with pleasure, learning, and habit formation.
