Q&A with John Constantino: Solving the biomarker conundrum
Biological factors that reflect autism’s roots may differ from those that influence how severe the condition is. Failure to make a distinction has stymied the search for biomarkers.

Gene-activity map of developing brain reveals new clues about autism’s sex bias
Boys and girls may be vulnerable to different genetic changes, which could help explain why the condition is more common in boys despite linked variants appearing more often in girls.
