The Lead

An Accessible Approach to Making a Mini-brain

October 5, 2015 | by Brown University | Comments

In a new paper in Tissue Engineering: Part C, researchers describe a relatively accessible method for making a working – though not thinking – sphere of central nervous system tissue. The advance could provide an inexpensive and easy-to-make 3D testbed for biomedical research.

Team Characterizes Genetic Mutations Linked to a Form of Blindness

October 2, 2015 10:38 am | by University of Pennsylvania | Comments

Achromatopsia is a rare, inherited vision disorder that affects the eye’s cone cells, resulting in problems with daytime vision, clarity and color perception. It often strikes people early in life, and currently there is no cure for the condition. In a new study, scientists has identified two naturally occurring genetic mutations in dogs that result in achromatopsia.
