There's a persistent fantasy that maybe some other nice countries will start mass-hiring US scientists. That's not going to happen. A few high-profile, big name researchers will get poached, sure. But most countries, including some very nice ones, are underemploying their own scientists already.

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case.
