Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.

As with any trade show, flashy, high-end products have a tendency to steal the lion's share of the spotlight at MWC -- but the fact is, featurephones still outsell traditional smartphones by an order of magnitude. Companies like INQ are betting the farm on the belief that today's ultra-connected generation of Twitter, Myspace, and Facebook users are ultimately going to pick fashionable, cheap, easy-to-use handsets over the complexity of an iPhone, G1, or Omnia. There's something to be said for that -- most people don't know the model of their own phone, after all, and have no interest in learning how to download and install an app, let alone learn an entire mobile operating system. Plus, for the youngest members of this profitable group, there's a lot of price sensitivity -- smartphones are typically out of reach.

If startup Sonar has its way, that's where its new platform comes in. The idea was to fundamentally rethink the way average consumers -- you know, the ones who are plugged into three, four, or fourteen social networks and don't know a G1 from a P1i -- use a phone to communicate, and they're ready to show off their efforts for the first time here at MWC. We had an opportunity to sit down with Sonar's founders this week for a tour of the system, and we're pretty stoked about what we saw. Read on.

To be exceptionally honest with you, Ultrasonic Batgoggles don't exactly need any pimping from us. What you see above is a homegrown device that enables humans to discover how bats must feel when using echolocation in order to judge how far away certain objects are. The main components are an Arduino microcontroller clone, Devantech ultrasonic sensor and a set of welding goggles -- oh, and a sick poker face to really round things out. Check out the links below to get a gist of the background as well as a step-by-step guide to concocting your own.

We've all heard the diehards claiming that the whales are the ones we should save, and thanks to an autonomous glider crafted by Webb Research, they're finally getting their wish. Recently, a trial was pursued in which a radio / satellite phone-equipped Slocum Glider was sent up to 200-meters beneath the depths in order to survey, pinpoint, and record location data for various whale pods swimming about. The device then surfaces and "phones home" the recently gathered information, which can then be disseminated out to ensure nearby vessels don't enter whale-packed territories. Jim Theriault of Defense Research and Development Canada, Dartmouth ran the experiment, and noted that this iteration of whale sensing and reporting improved on previous attempts by being uber-stealthy, featuring a remote data reporting system, and boasting a signal processor capable of tracking even the baleen whale's "lower-frequency call." Currently, the torpedo runs on batteries which last a month or so without needing a recharge, but future renditions are planned to scour the waters for "between five months and a year" by utilizing a special recharging gel. Look for these to hit your nearest ocean later this summer, and try not to be too alarmed when it surfaces beside your craft.
