'Layered-layered' materials promise longevous Li-ions

Posted May 14th 2007 9:54AM by Darren Murph

It's been a tick since we've heard details on an emerging battery technology that promises to trounce even the best products currently available, but researchers at the Department of Energy's Argonne National Laboratory have reportedly developed yet another approach to boosting Li-ion capacity and stability. The technology is "based on a new material for the positive electrode made of a unique nano-crystalline, layered-composite structure," which allows an active components to provide for charge storage while residing in an inactive components which assists in keeping the risk of explosion low. Current claims are putting the capacity right around "double that of conventional Li-ion cells," and it could be used in a variety of wares from "mobiles, laptops, pacemakers and defibrillators, or even hybrid / electric vehicles." Unfortunately, there was no timetable as to when scientists expected said technology to actually be available commercially, so until then, we'll consider this yet another promise on pause.

3G option coming to MacBook Pros?

Posted May 14th 2007 10:34AM by Thomas Ricker

Not that any of this should be a surprise, but AppleInsider says that Apple may offer a "3G wireless" option on future notebooks. Citing an "unproven but seemingly credible source," the venerable rumor mongering site says that Apple has asked for a PCI Express mini-card adapter to integrate a WWAN module inside the display lid of some future Apple laptop. While the source would not state which 3G technology would be used or which laptop(s) would benefit, HSDPA in a MacBook Pro is certainly the most likely combination what with Apple's new found love-in with AT&T. Best part? Bluetooth back to your WWAN-enabled MacBook and you've got the world's first 3G iPhone.

Samsung poised to introduce white LED-backlit displays

Posted May 14th 2007 4:04PM by Erik Hanson

Samsung LED LCD televisionSamsung believes that by 2010, 30% of all LCD televisions will include LED backlights instead of the conventional flourescent used in most sets now. What's different from the LED units we've seen before is that Samsung wants to use white LEDs, with single diodes custom-coated to produce the same backlight previously requiring combinations of red, green, and blue bulbs. Samsung recently invested in Intematix, which produces custom phosphor coatings for LED bulbs to create uniform color -- required in a television to faithfully reproduce colors. Until recently costs have been higher for LED backlight units, keeping them relegated to higher-end models. Samsung claims the single bulb process reduces costs by 40%, but time will tell whether white-only LEDs are truly better or cheaper than tri-color LEDs, or if they are just the next "Reveal lightbulb" marketing gimmick.

Fujitsu's 250GB slimster for ultra-portable laptops

Posted May 15th 2007 5:28AM by Thomas Ricker

Slide on over Samsung, you'll need to make room on your "world's biggest" pedestal for Fujitsu's new 250GB, 2.5-inch drive for laptops. The MHY2BH matches Samsung's line-up nearly spec-for-spec: 12-ms average seek, 8MB cache, SATA interface, 5,400rpm, 24dB operational wheeze, and a slightly better 1.9W power draw. Still, neither can match the 300GB capacity of Fujitsu's other 2.5-incher. But Fujitsu's latest, just like Sammy's, measures in at a mere 9.5-mm thick -- a full 3-mm less than the 300GB beast -- making these the highest capacity drives available in the ultra-portable slimsters we all crave.

New DNA Art from the UK

If you're anything like us, you probably appreciate the convergence of art and science slightly more than the average Joe; there's just something extra appealing about sleek, aesthetically attractive representations of the hyper-complex. We found some of this cool 'DNA Art' a while back from a company called DNA11, but it seems they're finally being challenged from the Brits at DNA ART UK Limited. They'll run your DNA as a graphical interpretation (the method that seems to have been popular in the past), but they'll also etch out every letter of your DNA code into a cube of crystal. A little more unique than that Van Gogh print you've had on your wall since college, eh? Just be careful if you're a wine mogul using your DNA to protect your cellar.
