Watch This: Video Tech Reveals Invisible Color and Movement

Forget 3-D and HD. This new kind of video isn’t almost as good as real life; it’s even better. The technique amplifies colors and movements that are invisible to the naked eye. The resulting view is not only enhanced but dynamic.

“What we’re doing here is a particular project at the intersection of vision and graphics that we call motion magnification,” said Michael T. Freeman, one of the project’s researchers at MIT’s Computer Science and Artificial Intelligence Lab.

Measuring imperceptible changes in color and motion has been around for some time, but this algorithm is the first to capture and visualize these subtle variations on video. The intended applications were medical—visually monitoring the pulse of newborn babies without having to touch them. When tested against conventional methods of taking the pulse (or an EKG in this case) the numbers matched up, according to a NYT blog.

It’s just a pile of sand–no wait, is that a tentacle wriggling in the corner? These time-lapse videos taken by researchers at the University of Queensland show that mushroom corals unearth themselves by slowly inflating and then deflating over 10 to 20 hours. See a second coral attempt the same after the jump.

The many-times-magnified photos of the Nikon Small World photomicrography contest entrance us year after year, with mesmerizing close-ups of nature’s microscopic marvels. Now, in the first Small World in Motion movie competition, we get to see the world’s wee wonders in action. The three winning films and eleven honorable mentions chronicle circulating blood, budding yeast, gestating eggs, and more.

First Place: This time-lapse video, at 10x magnification, traces the path of ink injected into an artery of a three-day-old chick embryo. As the ink spreads through the chick’s vascular system, the branching blood vessels and beating heart become clearly visible.
