    The use of laser as a means of data transmission is hardly anything new, but the current crop of laser diodes can only handle so much stress, provided that they don't fail in the first place. Luckily, the geniuses over at the University of Central Florida are about to deliver a smaller yet more intense and more reliable diode, which will lead to many more potential applications even beyond the scope of networking -- think cheaper, more effective hair removal. Little is said about how Professor Dennis Deppe's team made this possible, but once they work out how to optimize the operating voltage for better efficiency, Deppe reckons we'll see diode-embedded high speed, high bandwidth cables in the shops in four or five years' time. Seriously, we'd do anything to keep our latency low for some HD gaming action.

  • Phone glitch lets Kansas residents set off tornado alarms by misdialing

    Sounds like fun, no? Find the super-secret phone number that triggers a citywide tornado alarm, dial it up, and watch as Hutchinson, Kansas goes berserk. That's essentially what happened this past week, when an AT&T "software glitch" caused the security systems surrounding the tornado lines to vanish. When the system operates correctly, these sensitive phone numbers can only receive calls from three specific phones; if and when those phones call, alarms are set off to warn residents of impending danger. Due to this here "glitch," all phone numbers were able to dial in, which led to a smattering of false alarms when locals misdialed and accidentally rang the tornado hotlines. Thankfully for everyone involved, the issues have since been fixed, but there's been no word on whether these folks were simply trying to guess Dorothy's unlisted digits.

  • Vision Digital Video Phone marks underwhelming return of Ojo

    Well, this answers that. Back in early 2008, we wondered whether or not Ojo had gone dark once and for all, but it seems as if the video calling outfit has been brought back from the grave... for no apparent reason. The Ojo Vision Digital Video Phone is now on sale through the company's revived website, offering a 7-inch color LCD, a video output and a design that simply had to have been ripped straight from 1994. Of course, it's not like we haven't been to this rodeo before -- Verizon itself gave it a whirl (twice!), and promptly decided that its funds would be better spent elsewhere. We suppose not everyone is ready to move right along to mobile video calling, and if that's you, the source link has all the details on monthly plans. Just grab a paper grocery bag to wrap the unit itself in, okay? Trust us, it's for the best.

  • Researchers demo "unbreakable encryption" based on quantum cryptography

    Call us devilish, but we just can't help but love these types of stories. Here we have yet another overly confident group of researchers grossly underestimating the collective power of the hacking underground, as gurus from all across Europe have joined together to announce "the first commercial communication network using unbreakable encryption based on quantum cryptography." Interestingly enough, quantum cryptography has already been cracked in a kinda-sorta way, but that's not stopping these folks from pushing this claim hard to government agencies, financial institutions and companies with distributed subsidiaries. We've no doubt this stuff is pretty secure, but the last time we heard someone utter a claim similar to this, we saw him uncomfortably chowing down on those very words merely months later.[Via Physorg]

  • NTT DoCoMo's forward-looking video overlooks the present

    We've seen prophets get their agendas past the marketing department a time or two before, but NTT DoCoMo's latest peek into the "future" seemingly forgets to look at what's actually available right now. The lengthy spot showcases how mobile phones will "one day" be even more tightly integrated into our everyday lives, and while the ideas of using mobile-based keychains and passwords, geo-locators, and video telephony are certainly novel, deeming them events of the future seems a bit ignorant. Additionally, it demonstrates the phone's ability to assist with grocery shopping, take care of hailing a cab, act as a tutor, and prevent children from straying too far away -- all of which have either already been implemented or are quite a ways along the development pipeline. Of course, the pen-sized handset with retractable holographic display certainly hasn't hit mainstream channels just yet, but otherwise it seems we're all way ahead of our time. The pseudo-futuristic video awaits you in the read link.[Via PSFK]
