Every cell in an animal's body carries the same DNA. Yet that single genetic blueprint somehow produces neurons that fire, muscles that contract, and tissues with entirely different jobs. How ...

One of the biggest quests in biology is understanding how every cell in an animal’s body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

As a researcher, I still remember the discomfort I felt every time I had to sacrifice laboratory animals for an experiment.

Karthik Shekhar and his colleagues raised a few eyebrows as they collected cow and pig eyes from Boston butchers, but those eyes — eventually from 17 separate species, including humans — are providing ...
