A new technique documents real-time action in neurons by harnessing the changes in light that take place when they fire.

Matthew State is both a dedicated clinician and a world-class geneticist, but his diplomatic style is a relic of his former adventures in politics.

Duplication or deletion of 16p11.2 — a much-studied chromosomal region with a strong association with autism — is present in 0.76 percent of people with the disorder, according to a meta-analysis published February in Genetics in Medicine.

A genetic database of autism genes, called Autism Database, or AutDB, details curated information for more than 200 mouse models of autism, according to a report in the January BMC Genomics.

Hallucinogens like LSD and MDMA may help people with autism become more sociable, but negative side effects argue against their use.

Mice that lack the gene for integrin β3, or ITGB3 — which regulates the levels of serotonin in the blood — groom themselves frequently and show less interest in stranger mice compared with controls, according to a study published in February in Autism Research as part of a special issue on mouse models in autism.

Six strains of mice lacking a gene associated with fragile X syndrome show radically different behaviors though they share the same mutation, researchers reported in January in Autism Research.

High school graduation marks the end of opportunities for social engagement and access to services for many young people with autism.

Rare mutations in TSGA14, a component of the centrosome — which is required for the generation of new neurons — may be associated with autism, according to a study published in January in the American Journal of Medical Genetics.

High-functioning adults with autism pass false belief tests with ease, but struggle with moral judgment in real-life situations.
