Researchers untangle the multifarious nature of muscle aging. So far, the only reliable treatment is exercise.

Scientists race to develop CRISPR therapies that could save the lives of kids with muscle-wasting conditions.

As robust efforts fail to reproduce findings of influential zebra finch studies from the 1980s, scientists discuss ways to reduce bias in such research.

Researchers are evaluating whether selecting one species to provide protection for many is the right approach.

Inserting human “mini-brains” into rodents has the potential to broaden scientists’ understanding of neurological disease, but raises quandaries about consciousness.

The gene-editing technology is already in trials for some rare conditions, with more human testing on the horizon.

Assessments of species vulnerability provide crucial information for conservation efforts. But the science behind them is still evolving.

Evolutionary changes in both the vocal tract and the brain were necessary for humans’ remarkable gift of gab.

Researchers are resurrecting proteins from millions of years ago to understand evolution and lay the groundwork for bioengineering custom molecules.
