Modern medicine's ability to keep us alive makes it tempting to think human evolution may have stopped. Better healthcare disrupts a key driving force of evolution by keeping some people alive longer, making them more likely ...

It was long thought that DNA, together with the genes encoded in it, determined genetic destiny. But equally important is coordinating when genes are turned on and off. In fact, the regulation of gene expression defines life ...
