Not that the whole using-cellphones-for-disease-detection is completely fresh, but the latest handset hack for medical purposes is still mighty impressive. UCLA researcher Dr. Aydogan Ozcan has essentially converted a standard cellphone into a portable blood tester of sorts, which is capable of detecting HIV, malaria and various other illnesses. Put as simply as possible, the device works by analyzing blood cells that are placed on an integrated off-the-shelf camera sensor and lit up with a filtered light source. Said light source exposes unique qualities of the cells, and from there, the doc's homegrown software interprets the data and determines what's what. So, has anyone given this guy the main line to NTT DoCoMo, or what?

Just imagine -- yapping for hours on end to your dream lover could actually leave your cellphone with more juice than what it started with. This completely bizarre scenario could theoretically become a reality according to new research from a professor at Texas A&M University, and it's all thanks to the magic of nanoscale piezoelectrics. If you'll recall, we've seen this technology generate energy in wearable devices before, so it makes sense that sound wave energy could also be captured and converted into electricity. Of course, we're still a good ways away from this being ready for commercialization, but who knows how quickly this could come together if placed in the capable (albeit unpredictable) hands of Dr. Walter Bishop.

For UK citizens willing to have their privacy infringed upon in the name of peace and quiet, C2C is the train company for you. The outfit has introduced a special "quiet" carriage in its trains in order to nix conversations and unexpected cellphone noises for those who would prefer. The cabin in question sports a special coating on the windows that allows light in but rejects WiFi and cellular signals. In order to keep the lawyers at bay, folks who sit in this jammed-up area are asked to agree to those terms beforehand, and just in case you sign while inebriated, there are a number of signs and announcements (um, defeating the purpose much?) informing them that no calls will be allowed. Happy trails!

Ask yourself this: Are you a statistic or a specific example? That's the question being raised in the aftermath of a study in which researchers secretly tracked the locations of 100,000 people to determine their movement patterns. Such studies are considered invasions of privacy -- and illegal -- in the United States, but this one was done in an undisclosed industrialized nation. The subjects were chosen at random out of a pool of 6 million from a mystery wireless provider and tracked based on cell tower triangulation and other "tracking devices." Study co-author Cesar Hidalgo at Northeastern University promises that researchers didn't know the individuals' phone numbers or identities, and offers that the results are a major advance for science. The study found that people are homebodies -- most stay within 20 miles of their home and are rather habitual. Scientists say the findings -- to be published in Nature on Thursday -- can help improve public transit systems and even fight contagious diseases.

Dropped calls have admittedly become less of a problem as carriers became more reliable in more locales, but it sounds like we finally have somewhat of a celestial answer as to why they happen in the first place. Thanks to research by David Thomson and colleagues at Queen's University in Canada (pictured above), they have discovered that when a "solar radio flare occurs and cell-site antennae are facing the sun, the number of dropped calls that go away for no apparent reason increases dramatically." In one particular case, it was noted that "20-percent of calls" were dropped during flares, and while some may be satisfied with cranking out these results and darting away, the team is still interested in finding out the reasons why calls still drop in the absence of flares. And to think, all this time we were having way too much fun blaming the carriers.
