In collaboration with partners including the University of Sydney, they profiled nearly 680,000 cells from the fetal brain to chart the full cellular landscape.

Researchers studying three groups of people -- individuals with autism, those with fetal alcohol syndrome, and a "neurotypical" control group -- found that cognitive ability strongly influenced how well participants understood speech in noisy conditions.
