At some point, humans crossed a line no other species crossed quite the same way. We stopped just reacting to the world and started explaining it. Scientists have argued for decades about when that happened. Now DNA may have pushed the answer way, way back.

For thousands of years, great civilizations seemed permanent—right up until they weren't. Nearly every civilization that collapsed believed it would somehow avoid the fate of those that came before it. Now, scientists studying these collapses are saying that we could be next. And it could happen sooner than we think...

There’s no shortage of college rankings—but they rarely agree. So instead of relying on just one, we combined the three biggest and most important ones out there: U.S. News, QS World Rankings, and Times Higher Education.

No one is perfect, and the same is true for the American states. While each one has some wonderful things about it, there are some—shall we say, not-so-wonderful things as well that bear mentioning. So, let's mention them...

Some states make retirement look pretty easy. Others? Not so much. Whether it's healthcare headaches, rising costs, long drives to basic services, or just a feeling that retirees aren't exactly the priority, some states consistently leave older Americans less satisfied than others. The question is...how many of these states surprised you?

Not every state rolls out the red carpet for the older generations. But, some states really know how to make a Boomer feel right at home. We looked at where Baby Boomers say life feels a little (sometimes a lot) better—and a lot less stressful.

Recently researchers have narrowed the search for alien life dramatically, identifying 45 worlds that offer some of the best chances of finding it. We ranked the 30 most intriguing candidates.

Humanity's origin story has seemed fairly straightforward for years. Scientists knew modern humans evolved in Africa, and while plenty of details remained debated, the broad outline appeared settled. Then a team of researchers took a much closer look at ancient genetic patterns hidden inside modern DNA.

We looked back at the best states in America in 2006 and compared them to where they rank today. Some of the changes are pretty surprising.
