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.

Emotion research has a communication conundrum
In 2025, the words we use to describe emotions matter, but their definitions are controversial. Here, I unpack the different positions in this space and the rationales behind them—and I invite 13 experts to chime in.

Autism-linked copy number variants always boost autism likelihood
By contrast, varied doses of the same genes decrease or increase the odds of five other conditions, with distinct biological consequences, two new preprints show.

Everything everywhere all at once: Decision-making signals engage entire brain
The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.
