Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure has been lacking. Now scientists have identified new clusters of cells with differing patterns of gene expression in the amygdala of humans and non-human primates. The work could lead to more targeted treatments for disorders such as anxiety that affect tens of millions of people.

A new analysis has revealed detailed 3D maps of the internal structures of multiple tumor types. These cancer atlases reveal how different tumor cells -- and the cells of a tumor's surrounding environment -- are organized, in 3D, and how that organization changes when a tumor spreads to other organs. The detailed findings offer scientists valuable blueprints of tumors that could lead to new approaches to therapy and spark a new era in the field of cancer biology, according to the researchers.

In common marmosets, the brain regions that process social interactions develop very slowly, extending until early adulthood, like in humans. During this time, all group members are involved in raising the infants, which contributes to the species' strong socio-cognitive skills.
