"The scientists noticed that during sleep, the system that circulates cerebrospinal fluid through the brain and nervous system was "pumping fluid into the brain and removing fluid from the brain in a very rapid pace," Nedergaard says.
The team discovered that this increased flow was possible in part because when mice went to sleep, their brain cells actually shrank, making it easier for fluid to circulate. When an animal woke up, the brain cells enlarged again and the flow between cells slowed to a trickle. “It’s almost like opening and closing a faucet,” Nedergaard says. “It’s that dramatic.”
Nedergaard’s team, which is funded by the National Institute of Neurological Disorders and Stroke, had previously shown that this fluid was carrying away waste products that build up in the spaces between brain cells.”

"Spin symmetry here means atom interactions, at their most basic level, are independent of their nuclear spin states," Ye explains. "However, the intriguing part is that while the nuclear spin does not participate directly in the electronic-mediated interaction process, it still controls how atoms approach each other physically. This means that, by controlling the nuclear spins of two atoms to be the same or different, we can control interactions, or collisions."

"One of the interesting things about success is that we think we know what it means. A lot of the time our ideas about what it would mean to live successfully are not our own. They’re sucked in from other people. And we also suck in messages from everything from the television to advertising to marketing, etcetera. These are hugely powerful forces that define what we want and how we view ourselves. What I want to argue for is not that we should give up on our ideas of success, but that we should make sure that they are our own. We should focus in on our ideas and make sure that we own them, that we’re truly the authors of our own ambitions. Because it’s bad enough not getting what you want, but it’s even worse to have an idea of what it is you want and find out at the end of the journey that it isn’t, in fact, what you wanted all along.
