If you think all living things need oxygen to breathe, you’re thinking too much like a human.
It’s true that humans, along with mammals, birds, insects and fish, require oxygen for survival. But not bacteria. What bacteria lack in intellect, they make up for in extraordinary adaptability of their metabolism.

The 13,000-year-old wisdom tooth of a Native American teenage girl was pulled from an underwater cave below Mexico’s Yucatan Peninsula.
"This young woman’s misfortune, so long ago, provides us with new insights regarding the early people who populated the Americas," said Laura Zahn, senior editor at Science.

Part of your body is going extinct right now

We’re not talking about your appendix.

We’re referring to microbes — a good bacteria that boosts your immunity, protects you from infection and produces the enzymes you need to digest your food.

But due to the overuse of antibiotics, C-sections and modern sanitation, humans in the U.S. have lost a third of their microbial diversity, mostly on their skin and in their stomachs and digestive tracts.

This computer simulation of a hummingbird in flight, surrounded by turbulent vortices of air.  Haoxiang Luo, a professor of mechanical engineering at Vanderbilt, built this incredibly detailed simulation based on videos of the real thing (captured by Ty Hedrick at UNC):

When most birds fly, they produce lift as their wings flap downwards, but when their wings flap back up, they do the opposite - they produce a little negative lift.  But hummingbirds tilt their wings so they produce positive lift on both upstroke and downstroke.

Luo’s research could be used to help perfect a hummingbird drone. One company in California has already given it a try. Here’s an early prototype, in slow mo, followed by a newer version with a camera attached:

Hypnotizing, no?

While on a reporting trip in the Philippines, science correspondent Miles O’Brien underwent emergency surgery after an accident. The doctor had to make a choice between a life and a limb, ultimately leading to the amputation of Miles’ left arm.

On Friday, Miles sat down with Judy Woodruff about life after the loss of his arm. 

We remain in awe of his bravery.
