These fully washable shirts are using nanotechnology to weave a conductive fiber grid into the cotton fabric to monitor your movements or your heart rate and transmitted wirelessly to a central computer.

Ellis D. Tripp writes to tell us BBC News is reporting that mega-retailer, Wal-Mart, is now fighting it out with a man who claims to have invented the 'smiley face' logo, and has been marketing it since the '70s. From the article: "Until now the smiley face had been considered in the public domain in the US, and therefore free for anyone to use. Wal-Mart spokesman John Simley told the Los Angeles Times that it had not moved to register the trademark until Mr Loufrani had threatened to do so."
