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.

Null and Noteworthy: Neurons tracking sequences don’t fire in order
Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)
Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.
