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.

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.
