Leanne Williams explores how brain imaging could help explain biological differences among people with similar mental-health symptoms. She describes research on brain-network patterns in depression and the possibility of using those measurements to support more individualized diagnosis and treatment.

Nicholas Weiler talks with Guosong Hong about overcoming the limited penetration of light into brain tissue. Inspired by transparent tissues in glass frogs and the eye, Hong describes approaches involving fluorescent nanomaterials, focused ultrasound and molecules that temporarily reduce optical scattering. The conversation examines experiments with a common food dye and a project to genetically engineer mice with transparent brains from birth. These techniques could provide new ways to observe neural circuits and study how the brain develops and functions.
