Autonomous Wave Glider bot launched to track sharks, beam real-time data to your iPhone and iPad
When they're not breaking world records, fuel-hating Wave Glider seabots like to indulge in other hobbies, like shark tracking. One of the vessels has just been launched off the coast near San Francisco (vid after the break), adding a mobile worker to the existing local network of buoy-mounted receivers. They monitor the movements of electronically tagged sea life, including the fearsome Great White, picking up signals within a 1,000-foot range while researchers from Stanford University analyze the data from the safety of the shore. Better still, the free Shark Net iOS app gives anyone the chance to track these things, and activity should increase as the monitoring network (hopefully) expands along the west coast and more bots are introduced. You didn't think the world's fascination sharks was limited to only a single single week, did you?
Scots lose sight of early release offenders due to faulty electronic tags
We haven't yet heard of any problems with the RFID tags increasingly being used to monitor inmates in prisons, but it looks like the electronic tags used to keep watch on early release offenders are decidedly less reliable, at least according to a recent investigation into the matter in Scotland. As The Scotsman reports, out of a total of 987 tagging orders issued, there were 285 incidents where the tags failed, with dead batteries the biggest culprit. That rather obvious problem accounted for 185 of the cases, with damage to the unit by the offender, problems with the black box in the offender's home, and a weak signal rounding out the technical difficulties. That, as you might have guessed, has lead some to question the Scottish government's practice of relying on electronic tags to monitor early release offenders, but the government seems to be sticking to its guns, with a spokesman saying that "a breach does not necessarily equate to reoffending," although, as the Scotsman reports, it did recently scrap a plan to tag suspects who were allowed out on bail.[Photo courtesy of The Daily Mail]
