How I learned to stop worrying and love preprints
Preprints are gaining traction in biology, but some researchers have lingering concerns. Should they?
Burning debate: What’s the best way to nab real autism genes?
How to best use a large volume of data to discover new genetic risk factors for autism is a matter of intense debate, particularly in light of historical challenges.

To persist, memories surf molecular waves from thalamus to cortex
During the later stages of learning, the mouse brain progressively activates transcriptional regulators that drive memory consolidation.

Sex hormone boosts female rats’ sensitivity to unexpected rewards
During the high-estradiol stages of their estrus cycle, female rats learn faster than they do during other stages—and than male rats overall—thanks to a boost in their dopaminergic response to reward, a new study suggests.
