Who would have believed we'd be altering the genetic make-up of animals so they can grow replacement organs for us? Who'd have believed the drink machine in the foyer dials for supplies when it senses it's getting low? At the dawn of the new millennium the future seems to be coming ...
The study analyzed 96 Anolis lizards, comparing the genetic makeup of forest-dwellers to those living in Puerto Rico’s capital. Scientists found that 33 genes within the lizard genome were repeatedly associated with urbanization.“You can hardly get closer to a smoking gun,” said Wouter Half...

As I’ve learned through the foundation’s work in this field, it’s one thing to make modest improvements in a few classrooms, and another thing to spark big improvements at scale. If we’re lucky, we’ll hit some of our milestones within three years and be able to prove out these ...

The end result: the genetic makeup of a population shifts towards being more conducive to reproduction within a range of environmental settings. But there’s no Trumpist bleach-drinking allele, nor an allele for politically particular cabin fever. As far as I know, there’s no Florida Man al...
