Tiny geolocators track birds flying 1,600 miles across the Atlantic
It's easy to prove that big birds like gulls will cross oceans when they migrate, but tiny birds are another matter -- the trackers you need are usually enormous in comparison. The Vermont Center for Ecostudies wasn't daunted, though. It successfully tested extra-small geolocators on blackpoll warblers, migratory songbirds that are too small and light (0.4oz) to shoulder previous sensors. The newer device weighs just 0.02oz, and is no bigger than a dime. As you can see above, it was more of a minor inconvenience than a heavy burden.
Geolocator-equipped backpacks to track bird migrations
We've seen birds tasked with carrying around sensors in order to provide data about external happenings, but up until now, tracking birds' migration patterns from start to finish has been a tedious, if not impossible task. Gurus from York University in Toronto have apparently figured out the solution, and it all sounds much simpler than you might imagine. By equipping birds with minuscule "backpacks" -- which weigh less than a dime and use geolocators to collect all sorts of information about flight times, patterns, stopovers and speed -- scientists can get an accurate look at where the animals were and when they were there. In a recent test involving 34 birds, researchers were able to retrieve the packs from 7, and while that may not be a majority, biologist J. M. Stutchbury noted that this "was 7 more than anybody else." Right you are, Doc.[Via New York Times, image courtesy of PaulNoll]
Inventor crafts GPS-equipped shoes, includes a panic button
We've seen some fairly interesting means of keeping track of your mischievous kids (or pets), but Sayo Isaac Daniel's latest invention takes top honors as the ultimate paranoid parent's must-have gizmo. Aside from the obvious tracking uses, Daniel's GPS footwear is actually intended to beam out a distress signal to a pre-selected recipient if the wearer hits a certain panic button. The GPS-equipped kicks would present the location of the violated victim to whoever is deemed that person's hero, and would hopefully give the rescuer enough time to arrive and lay down the law. Also, the patent explains an "alarm toe switch" that would be inserted within the shoe in order to give customers the ability to sound their alarm (intentionally or otherwise) without making any sudden movements. Reportedly, a company dubbed Quantum Satellite Technology plans to start selling the shoes "in March for around $350 per pair," but the GPS signal emanating from your soles won't do you much good if your kidnapper ditches your footwear before tossing you in the trunk.[Via The Raw Feed]
