Anthony Lynn cracks open a can of Coca-Cola. “I’m not sure what to do with myself right now,” he admits.

It all started with a conversation between siblings 10 years apart.

Carnegie Mellon University announced the launch of what it says is the nation's first bachelor's degree in artificial intelligence, which the Pittsburgh institution hopes will extend its brand as a computer science training hub. The private research institution, which already offers nearly a dozen courses with AI theory and practical training, built the degree program's curriculum around mathematics, computational modeling and statistics, among other topics.

By ruling Monday that any state can allow sports betting, the nation's highest court set America on track for what may be a historic expansion of its legal gambling offerings.

A Supreme Court decision Monday that could lead many states to legalize sports betting may provide some pocket change for those governments but not enough to help head off looming budget crises in a few years, experts say.

Odysseus, who voyaged across the wine-dark seas of the Mediterranean in Homer’s epic, may have had some astonishingly ancient forerunners. A decade ago, when excavators claimed to have found stone tools on the Greek island of Crete dating back at least 130,000 years, other archaeologists were stunned—and skeptical.

We've been up here for three days, trekking the 10,000-foot ridges of the Schell Creek Range of east-central Nevada. I take a heavy breath and continue along another granite-and-limestone slope flecked with bristlecone pines — gnarled, 2,000-year-old survivors found only in the American West's highest, harshest landscapes. The searing in my legs and lungs eases as the severe incline levels out into a grassy meadow ringed by aspens, their leaves quaking in the cool breeze. Donnie Vincent holds up a hand to halt me, and grins.
