Oil-based color pixels could let you watch videos on e-paper

By rapidly manipulating colored oil droplets stacked on top of each other, a new electrowetting (EW) technique could lead to the development of electronic paper displays that can produce high-resolution color video. Displays that use the EW effect could have several advantages over today’s e-readers and other portable flat panel displays, most of which are based on electrophoretic (EPh) technology.

Researchers have demonstrated a vertical stack approach for electrowetting displays that can produce high-resolution color video. Top: A diagram of the device structure. Bottom left: Photographs of the pixel array with all pixels off (a) and on (f); numbers indicate the voltage applied to each layer. Bottom right: Graph showing the switching speed of each color.

The Raw Energy Used in Sports

Did you ever wonder how much energy or how much power athletes expend when performing? Certain sports require a small amount of energy to be very precisely directed, while other sports require a large amount of energy to be exerted in a very short amount of time. The following infographic takes a visual look at how much energy atheletes in some of the most popular sports are expending.

Mobile Advertising and the Rise of Digital Coupons

Mobile is firmly establishing itself as a crucial advertising channel, and the companies who aren’t utilizing it look set to be left behind. More than two thirds of the population are in possession of a mobile phone, and it’s obvious to see why the direct nature of mobile advertising is so appealing to businesses.

How much space crap is circling the Earth?

This illustration created by Australia's Electro Optic Systems aerospace company shows a view of the Earth from geostationary height depicting swarms of space debris - approximately 50,000 of the half-million or more objects bigger than 1cm - in Low Earth Orbit. An Australian company said that it had developed a laser tracking system that will stop chunks of space debris colliding with spacecraft and satellites in the Earth's orbit. Electric Optic Systems said lasers fired from the ground would locate and track debris as small as ten centimetres (four inches) across, protecting astronauts and satellites. Debris on the eastern side of the image are in the Earth's shadow and so not visible to the eye.
