Hasta La Gadget!

Science has been figuring out ways to sidestep those dreaded finger pricks for years now, but it’s not often that we hear of such a permanent solution as this. A crew of researchers from The University of Tokyo and BEANS Research Institute are in the process of developing a newfangled blood sugar sensor that “reacts to glucose and lights up inside the body.” ‘Course, injecting dyes into humans in order to receive interpretable signals ain’t exactly new, but hydrogel is what makes this approach unique. As the story goes, this jelly-esque material can be implanted within the body, enabling blood sugar levels to be monitored and measured externally with no pain or irritation whatsoever. In theory, a monitoring system could trigger an alert as soon as the internal levels dipped or rose beyond a predetermined extreme, giving those with diabetes a maximum amount of time to get things back in balance. There’s nary a mention of when this goo will be green-lit by the FDA, but there’s definitely a video explaining everything just past the break.

Man, if only this had been discovered before Ariadne was tasked with building impossible dreams. A team of scientists caught high-fiving over at Lawrence Berkeley National Laboratory have a new and riveting announcement to share, and it revolves around our old and trusted friend, graphene. This go ’round, the self-proclaimed “extraordinary form of carbon” is being stressed to its max, but not without good reason. Thanks to inquisitive minds and a “stroke of serendipity,” a research team was able to create magnetic fields in excess of 300 tesla by simply straining graphene in a certain way. For physicists, the discovery is a dream come true, particularly when you realize that magnetic fields in excess of 85 tesla were practically impossible to come across in a laboratory setting. The benefits here? It’s honestly too early to tell, but gurus in the field are already suggesting that the “opportunities for basic science with strain engineering [are] huge.” Something tells us Magneto would concur.

You’d think with ATI having the performance, value and power efficiency lead for so long — at least since the Radeon HD 4000 series — NVIDIA would be in all kinds of trouble, but it’s only now that AMD’s graphics division has finally taken the lead in quarterly shipments. This is according to Mercury Research, whose analysts place the split at 51 to 49 percent in favor of ATI — still a tightly contested thing, but it compares very favorably to the Red Team’s 41% share in the same quarter last year. This data is concerned with discrete GPU shipments only (laptops included), whereas on the integrated front Intel continues to reign supreme with 54 percent of the market shipping its cheap and cheerful IGP units. ATI has made forward strides there as well, however, with 24.5% ranking ahead of NVIDIA’s 19.8%. If Apple shifting its iMac and Mac Pro lines away from the Green livery wasn’t enough, perhaps these numbers will finally start ringing some alarm bells over at NV HQ.

The fabled cloak of invisibility was once considered impossible for modern science, chilling out with perpetual motion up in the clouds, but these days scientists are tilting at blurry windmills with a modicum of success several times a year. The latest advance in theory comes to us from Michigan Tech, which says it can now cloak objects in the infrared spectrum. Previous attempts using metallic metamaterials could only bend microwave radiation, the study claims, but using tiny resonators made of chalcogenide glass arranged in spokes around the object (see diagram at left) researcher Elena Semouchkina and colleagues successfully hid a simulated metal cylinder from 3.5 terahertz waves. While it’s hard to say when we might see similar solutions for visible light, even a practical application of infrared cloaking could put your night vision goggles to shame, or perhaps block covert objects from being detected by those newfangled terahertz x-rays.

Who knew HP was such a big player in the display business? Just days after announcing that a flexible display from Mars may very well hit the market out of Hewlett-Packard’s own laboratories, a fresh report has surfaced over at Technology Review surrounding yet another display tech that the company is feverishly working on. It’s bruited that the outfit is “developing new materials for brighter low-power displays” — think E Ink, but with color… and a twist. Frustrated with what nature was offering (or not offering, as it were), scientists at HP decided to concoct new materials that “use ambient light to create a more vibrant color for video-capable, low-power screens.” It’s hard to say just yet whether or not this stuff will end up suitable for mass production; we’ve been hearing about color e-paper for years now, and even though Qualcomm’s Mirasol display showed great promise at CES, we’ve yet to hear of any progress towards a market-ready product. Hit the source if you’re thirsty for technobabble, but don’t go looking down on that Kindle just yet.
