Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future ...

Researchers have long faced a blunt limitation in biology. They could delete proteins or switch genes off, but they could not finely tune how much of a protein existed in specific tissues over an ...
