South Koreans Discover 'True Blue' Material for Better OLED Screens [Feeling Blue]
You see, OLEDs, for all their potential greatness, have a heck of a time producing the blue light necessary to produce great images (red, green, blue light makes TVs happy!). Red and green light works fine, but blue remained elusive. That's where the South Koreans come in.
The discovery was the work of Pusan National University chemistry professor Jin Sung-Ho, who said the discovery was an important one for advancing the energy efficiency of OLEDs. For gadget lovers, it's yet another piece of the puzzle that, when completed, will mean powerful, beautiful OLED TVs are a mainstay in homes across the world. [AFP]
I love Sonos, the super synced-up wireless music home system, but have always been a little freaked out by the price, about $750 to start, including the increasingly old-school-looking $400 scroll-wheel Controller. When I saw the 
What's great about the one ZonePlayer is that you immediately get the AirPort Express-like ability to grab music from your Mac or PC, plus the iTunes Remote app's ability to control it from a little handheld, but that's just the beginning. The ZonePlay! er comes with the ability to serve up web radio, Rhapsody, Napster, Pandora, Last.fm and Best Buy Music, all without a computer.
But I can walk away from the laptop (leaving it on) and instead pick up an iTouch lying on the coffee table, which lets me view the same exact tracks, and just as fast.
You probably now that Sonos offers free 30-! day no-c redit-card-required trials of Rhapsody, Napster and Sirius—the key, I think, is to try all three in a row, giving you basically 60 days of free on-demand music sampling, and a month of decent satellite radio, before you choose one, if any.
After the super-syncability and the multiple sources of music, the third best thing about Sonos is the fact that it is constantly being upgraded. So even though there are some technical advantages to the newer hardware (wireless-N is the big one), the basic functionality is the same, meaning buying at clearance shouldn't be a problem.
Emoji: if you've never heard of it, that's because you're probably not living in Japan, 12 years old, and a highly social schoolgirl. An emoticon standard that is widely used in the country, it was included in the iPhone 2.2 firmware on the SoftBank network, but not for anyone else. Apparently fed up with his lack of ability to graphically express his numerous LOLs, a developer has figured out a simple tweak to enable these icons system-wide, no matter which carrier you're with. Naturally, to show anything other than unintelligible strings of Unicode the recipient's phone has to support Emoji emoticons, but apparently all 2.2 iPhones, hacked or not, can display the icons. The patching process, after the jump, isn't terribly complicated.
Nanobioscience's AdminPatch sounds like a pretty amazing way to deliver drugs into the body: it's got a metal surface covered in millions of tiny microneedles that puncture the skin. You may instantly think "Ouch!" but since these are so small and pierce the skin shallow enough to avoid pain receptors, the system is apparently painless.
