Medscape, a trade medical publication, released their annual physician lifestyle report this week. They analyzed survey results from more than 14,000 US doctors practicing in 30 different specialities about how their work affected the rest of their lives in 2016.

The appendix is an organ thought to have gone the way of our wisdom teeth and body hair: At one point we all needed them, now people can get by just fine without them.

When one strain of the human immunodeficiency virus (HIV) made the leap from chimps to people in the early 1900s, it wasn’t the first time a virus of its kind had evolved to cross species borders.

Many Americans are going to miss US president Barack Obama when he vacates the White House. Days after the 2016 election, his approval rating was its highest since 2009.

Everyone’s favorite form of carbon sure is sparkly. And now, scientists have evidence that some of the largest natural diamonds come from deep down in the Earth, surrounded by blobs of hot, liquid metal.

It’s winter in the northern hemisphere. As temperatures fall, a lot of us are pulling out our winter coats and getting ready to hunker down inside.
