Although HDR photos are typically captured with still cameras, HDRinstant software allows them to be created from frames of video. Read More

"Hello, World" – Video beamed from ISS using laser-based communications

While the International Space Station may be mankind’s outpost for the conquest of space, it still leaves a lot to be desired when it comes to a decent YouTube connection. That’s because, for all its sophistication, the station’s communications system is still based on 1960s radio technology and has all the bandwidth of a soda straw. That changed this week as NASA took a step into the video age with the test of its Optical Payload for Lasercomm Science (OPALS) demonstrator, which saw a laser used to beam a video to Earth in seconds instead of the usual minutes.

Red Bull almost single-handedly created the energy drink market we know today, piggybacking on the rise of extreme sports to get its brand out there ... and delivering some truly memorable marketing stunts along the way. Here's our five favorites. Read More
