Because a new federal safety regulation says that firefighters must have a clear view of how much air is left in their self-contained breathing apparatus (SCBA), LEDs are being used to illuminate the indicator. The LEDs are easy to see through smoke and also function as a warning system to other firefighters. When operating normally, the LEDs give off a blue-green light; if assistance is necessary, the LEDs give off a yellow color. The series of LEDs selected for this task use a low amount of power, which means fewer battery replacements. For more information, go to the following website: www.ledtronics.com.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10.

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
