Alysson Muotri aims to build a ‘thinking’ brain as a model for autism — even if his colleagues consider that work controversial.

A new method enables scientists to grow organoids that reliably reproduce the diversity of cells at the brain’s surface.

Results from a new trial suggest that it’s safe to treat autistic children with umbilical cord stem cells. But parents must pay for the pricey infusions, and no one knows how or if the cells work.

Two new resources may aid the study of synapses, the junctions between neurons.

A novel cell culture device enables researchers to grow bundles of nerve fibers from stem cells, mimicking the tissue that connects distant parts of the brain.

A new technique leads to neuron cultures of consistent quality, enabling scientists to study how autism mutations alter neurons.

A new method for growing brain organoids allows them to survive for up to a year — more than four times as long as is possible with other methods.

A variety of genetic risk factors for autism may disrupt some of the same processes in cells.
