Among the persistent mysteries in epigenetics are the criteria by which specific regions of the genome are chosen for deposition of distinguishing chromatin marks.

How does auditory cortex respond to silence? In this issue of Neuron, show that activity in macaque auditory cortex is highly structured even in the absence of sensory stimuli. These data reveal a close link between spontaneous neural activity and the functional organization of auditory cortex.

Although the discovery of genomic imprinting dates back more than two decades, its significance for both disease pathogenesis and evolutionary theory is only now emerging. However, its effects had been observed for much longer, and if biologists had been influenced less by prevailing orthodoxies, they might have stumbled on it sooner. Mule breeders encountered the phenomenon three millennia ago...

When choosing between alternatives of uncertain quality, one can learn from other decision-makers either through communicating with them about the reasons underlying their choices, or through simply observing their choices. The former way of learning has been extensively studied in the word-of-mouth (WOM) literature, while the latter way, labelled silent word-of-mouth (SWOM), has received less ...
