Capturing autism’s sleep problems with devices nearable and wearable
Next-generation trackers could realize a long-standing research dream: conducting sleep studies in large numbers of autistic people.

Going on Trial: Epidiolex for autism; arbaclofen tests; pain monitoring
This month’s issue of Going on Trial takes a sneak peek at some early null results from a small trial of a cannabidiol-based drug for autism, among other recent drug developments.

Swings and misses with Jeremy Veenstra-VanderWeele
A careful clinician who prizes evidence, Jeremy Veenstra-VanderWeele is happy to embrace trial failures, as long as he learns from them.
Ruth Carper: Imaging the aging brain in autistic adults
Few studies have tracked how brain structure and function change across adulthood in people with autism. Carper and her colleagues are collecting data to fill this gap.

Autism-related genes converge on microglia and dopamine in zebrafish
The findings add to the growing evidence that genes with disparate functions can play similar roles in brain development.

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.
