With stem cell technology and lab-grown brain organoids, Sergiu Paşca seeks the causes of autism and other neuropsychiatric conditions.

Letting human brain organoids grow in animal brains could be an ethical new option for experimental studies of neurological disorders.

Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.
