Weighing up autism’s obesity crisis
Autism’s underlying biology, associated behaviors and treatments can all put people on the spectrum at serious risk for obesity.
Rare form of autism shows unique pattern of regression
More than 40 percent of children with Phelan-McDermid syndrome lose skills they once had, beginning, on average, at age 6.

The innovators: How families launch their own autism studies
Some parents are starting ‘N-of-1’ studies for autism, but their efforts don’t always get taken seriously.

The invisible link between autism and anorexia
Autism and anorexia may seem to have nothing in common, but below the surface, the two conditions are startlingly similar—and sometimes affect the same person.

Single-cell genomics technologies and cell atlases have ushered in a new era of human neurobiology
Single-cell approaches are already shedding light on the human brain, identifying cell types that are most vulnerable in the early stages of Alzheimer’s disease, for example.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.
