Cell stress may sap organoids’ usefulness in autism research
Some cells in brain organoids — 3D clusters of cultured brain cells — fail to develop fully.

Diabetes drug delivers multiple benefits for people with fragile X syndrome
Researcher Randi Hagerman is a big proponent of metformin — a diabetes drug that she is testing in people with fragile X syndrome. In fact, Hagerman takes the drug herself as a preventive measure against cancer.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.
