No, she’s not about to kiss her smartphone. She’s blowing into an NTT DoCoMo Sensor Jacket that’s turned the handset into a breath analyzer. This particular model will provide a readout of her blood alcohol content or alert her if she has bad breath. Two other models measure radiation and the user’s body composition (fat and muscle mass), respectively.

Lossless data compression seems a bit like a magic trick. Its cousin, lossy compression, is easier to comprehend. Lossy algorithms are used to get music into the popular MP3 format and turn a digital image into a standard JPEG file. They do this by selectively removing bits, taking what scientists know about the way we see and hear to determine which bits we'd least miss. But no one can make the case that the resulting file is a perfect replica of the original.

Not so with lossless data compression. Bits do disappear, making the data file dramatically smaller and thus easier to store and transmit. The important difference is that the bits reappear on command. It's as if the bits are rabbits in a magician's act, disappearing and then reappearing from inside a hat at the wave of a wand.
