That must have been one heck of a toothy smile—imagine regular pig teeth growing next to bioengineered human-ish ones. After ...

For the past two decades, scientists have been manipulating genes to grow human cells where you wouldn’t quite expect them.

“Sometimes redundancy has a way of showing up under certain conditions; they’re not truly redundant,” said Michael Snyder, ...
