Researchers shed new light on molecular pump that ejects anticancer agents

Sometimes cells resist medication by spitting it back out. Cancer cells, in particular, have a reputation for defiantly expelling the chemotherapy drugs meant to kill them. Researchers at The Rockefeller University have shed new light on a molecular pump that makes this possible, by determining its three-dimensional structure, down to the level of atoms.

UW study offers visual proof of how brain synapses shrink during sleep

Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses - the junctions between nerve cells - grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.
