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:

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.

More than 22 million tons of road salt — 139 pounds per person — is used nationwide each year to keep roads safe from snow and ice. But environmental concerns emerge after the snow melts and the salt compounds remain.

The ice-buster threatens valuable environmental resources, including plants, aquatic life and groundwater.
