As postdoctoral positions become longer but salaries stay low, many researchers say they must decide whether they can afford an academic career.

This month’s newsletter looks at the minority of autistic people who have an identifiable genetic cause for their condition, and at the fraction of autistic children who are obese.

A brain area called the tail of the striatum may account for the shift.

The calcium-sensing instrument translates neuronal activity into signals that can be detected via functional magnetic resonance imaging (fMRI).

The gene, dubbed NHIP, is in a chromosomal region that shows unusually low levels of DNA methylation in placentas from women who gave birth to autistic children.

Inspired by watching her autistic nephew grow up, Croen has also been an advocate for bolstering research and services for autistic adults.

Autism research tweets this week sounded multiple notes of caution — about mouse models, early interventions, genetic associations and leaky recruitment pipelines.

Here is a roundup of news and research for the week of 21 March.

The neurons, which have low levels of the gene ASH1L, sprout more branches after the treatment.

Deep-learning algorithms can cut through some of the noise in brain imaging data collected across different sites.
