The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras. Between camera switches, a gray and then black color slate will briefly appear. Since the ISS is in darkness during part of each orbit, the images will be dark at those times. During periods of loss of signal with the ground or when HDEV is not operating, a gray color slate or previously recorded video may be seen. Analysis of this experiment will be conducted to assess the effects of the space environment on the equipment and video quality which may help decisions about cameras for future missions. High school students helped with the design of some of the HDEV components through the High Schools United with NASA to Create Hardware (HUNCH) program. Student teams will also help operate the experiment. To learn more about the HDEV experiment, visit here: http://www.nasa.gov/mission_pages/station/research/experiments/917.html
Forget exoskeletons -- the famed research lab is now building "exomuscles."
Dennis P. Garland's insight:
"It’s easy to imagine applications beyond the battlefield pretty much anywhere manual labor occurs. Other potential uses include physical rehabilitation and therapy, including helping stroke victims regain movement or improving mobility for the elderly".

This is not a video trick. This person is pouring a transparent liquid which, all of the sudden, turns black. It's the magic of chemistry, Mr. White. The reaction above is called the iodine clock reaction, which is a classic demonstration of chemical kinetics. But there are others, more complex and cooler than this.
