Neuroscience: Pre-emptive blood flow p387
Electrical signalling among brain cells summons the local delivery of extra blood — the basis of functional brain imaging. Yet sometimes, blood is sent in anticipation of neural events that never take place.

Astrophysics: Galaxies in from the cold p388
Computer simulations of the cosmos suggest that cold streams of gas could underlie the unexpectedly high star-formation activity of many massive galaxies found to exist a few billion years after the Big Bang.
