The transition to environmental sustainability is underway, but it won't be easy

Transitions are never easy. Sometimes they are underway, and we are unaware of them. When New York City transitioned away from a manufacturing to a service economy, we lost a million people and 500,000 manufacturing jobs. ...

Giant laser from 'Star Trek' to be tested in fusion breakthrough

The breakthrough came in an impossibly small slice of time, less than it takes a beam of light to move an inch. In that tiny moment, nuclear fusion as an energy source went from far-away dream to reality. The world is now ...
