Contact lens that darken in UV light

Photochromic lenses that allow you to walk from inside to outside without putting on UV-filtering lenses have been around for decades. But the technology is just making its way to contacts.

Traditionally, these light-to-dark lenses have been constructed by coating a normal lens with a photochromic dye. When UV light hits the dye, the individual molecules expand, darkening the lens and absorbing light. Coating contacts, however, doesn't work so well.

So researchers at the Institute for Bioengineering and Nanotechnology in Singapore have laced contacts with a matrix on nano tunnels filled with these photochromic dyes. Not only has the team been successful in producing transition contacts; these contacts darken in the presence of UV light faster than standard lenses (just 10 to 20 seconds).

Super absorbent sponge sucks up 180 times its weight

That tiny, plastic-looking black cube up there can absorb up to 180 times its own weight in toxic waste without absorbing any water. How? As with just about every amazing and/or inexplicable scientific breakthrough nowadays, the answer is spelled N-A-N-O.

HP's new accelerometer changes how people interact with the environment

You've probably heard of or even owned a computer that automatically turns off its hard drive when it senses shock or heavy vibrations. That is an example of sensitive human-machine intimacy. Another example I like is tilting the iPhone to use it as the driving bar for my racing games. Well, that nifty human-to-computer interaction is about to go to whole new level.

Methanol fuel cells for gadgets forge forward

Direct Methanol Fuel Cell has licensed a patent from CalTech to build methanol-based gadget chargers, a week after Toshiba took the wraps off its own portable fuel cell.

The patent will allow Direct Methanol Fuel Cell to design smaller portable charging packages for devices, such as mobile phones, said Viaspace, the parent company of Direct Methanol Fuel Cell. The company said Monday it has a partnership with Samsung and others to commercialize methanol fuel cartridges.

A direct methanol fuel cell converts the liquid fuel methanol into electricity through a chemical reaction between oxygen and methanol. It's a technology that a number of electronics companies are looking at to extend the life of power-hungry devices, such as laptops and mobile phones.

Tele Scouter projects translations to your eye

If Japan-based NEC has its way, people who act as language translators could one day be replaced with head-mounted displays that project translations onto a retinal display. Come again?

The Tele Scouter system is composed of an eyepiece with a front-mounted camera and a mic that picks up conversations and sends the data to a small computer worn on the user's waist.

The computer then transmits information to a remote server, which does the heavy processing work converting the foreign speech to text, translating it, and wirelessly sending it back to the tiny eye display for viewing. That seems like a whole lot of work to get to, "he said, 'Welcome to my country!'", but we'll roll with the idea for now.

Truth is we could use a translator to help us make complete sense of the English on NEC's product page, but we do know the TeleScouter isn't ready to show up at the UN just yet (or maybe ever).
