University of Twente's new lens reveals the sub-100nm level with visible light

Small is beautiful, but only when you can see it. Specifically, we're talking about nanostructures -- including cellular organelles and nanoelectronic circuits -- around the order of 100nm. The problem is with a microscope, visible light only takes us down to a resolution of 200nm at best, and it's not always ideal to use conventional methods to boost the resolution -- you'd either have to dope the subject with fluorescent dye or use highly delicate equipment. Thankfully, the University of Twente has come up with a new type of lens that would solve this problem: in a nutshell, a nanoparticle is placed on one side of the gallium phosphide lens, while the other side -- disorderedly etched with acid -- takes in a precisely modulated laser beam and scatters it into a focal point of your choice. Sure, this sounds bizarre and ironic, but apparently the modulation is controlled in such a way that the scattered beam focuses much tighter than an ordinary beam would using an ordinary lens. Have a look at the comparison shots of some gold nanoparticles after the break -- that's some sweet 97nm resolution right there for ya.

Styrofoam touches electrodes to create incredibly fast-charging wonderbatteries

Elon Musk's heart may have already given up on the humble battery, lusting after capacitors, but researchers at the University of Illinois have think there's life in the 'ol cells yet, creating batteries that charge and discharge in seconds. They've found a way to create electrodes using polystyrene beads as a sort of substrate, tiny spheres helping to set the porosity of either the nickel-metal hydride or lithium-manganese capacitor material. By adjusting the size and density of the bean bag innards the team was able to create an electrode porosity of 94 percent, which is just a few ticks short of theoretically ideal for exposing the maximum surface area of the electrode to the battery material. This results in extremely fast charges and discharges, the NiMH cell hitting 90 percent capacity in just 20 seconds and discharging in as quickly as 2.7 seconds. While we don't know just what kind of charging system the team was using to achieve this, even assuming a high-amperage stream of electrons this is still a remarkable feat. But, like most major advances there's a drawback: similar to Toshiba's SCiB batts the capacity of these cells is only about three quarters what it would be using normal battery construction, meaning you'd need roughly 25 percent more mass to get the same range in your ultra-fast charging EV of the future. That might just be a worthy trade-off.

BrandFinance declares Google the most valuable brand in the world

Source: http://www.engadget.com/2011/03/25/brandfinance-declares-google-the-most-valuable-brand-in-the-worl/

Well, it looks Eric Schmidt wasn't far off when he said recently that Microsoft is bigger competition than Facebook for Google -- at least when it comes to overall brand value, that is. According to BrandFinance's latest annual ranking, Google has just barely edged out Microsoft for the title of most valuable brand in the world, with the pair of them pushing Walmart out from the number one spot last year. As for Facebook, it just entered the top 500 for the first time at number 285, while Apple jumped twelve spots to make its first appearance in the top ten at number eight -- a shift that partly comes at the expense of usual suspect Coca Cola, which has dropped out of the top ten for the first time. The biggest loser? Nokia. It dropped all the way from number 21 last year to number 94 this year. Hit up the source link below for the complete list.

Xperia X10 to get Android 2.3 this summer, makes us rub our eyes in disbelief

Source: http://www.engadget.com/2011/03/25/xperia-x10-to-get-android-2-3-this-summer-makes-us-rub-our-eyes/

Who's in charge of Sony Ericsson today and what did they do with the old crew? Reversing a previous statement saying there'll be no Android updates for its Xperia X10 family beyond Eclair, SE has just announced that it'll bring Gingerbread to the X10 at the end of Q2 / start of Q3 this year. That's right around this summer, when we should expect a user experience roughly equivalent to that on the new Xperia Arc, Neo and Play devices, whose Gingerbread implementation looks to have served as the basis for the elder X10's upcoming update. Seriously, Gingerbread on the X10, we still can't believe it.

[Thanks to everyone who sent this in]

Kingston's Class 10 microSD family gets bigger, stays tiny

Source: http://www.engadget.com/2011/03/23/kingstons-class-10-microsd-family-gets-bigger-stays-tiny/

Kingston is putting an extra boost the smallest of its tiny memory cards. The popular provider of flash storage is upping its 4GB and 8GB microSDHC cards from Class 4 specifications (up to a 4 MB/s transfer rate) to a whopping Class 10 spec and all of its 10 MB/s goodness. The newly announced models join a 16GB version that has been available for several months. By completing the family tree of Class 10 cards, Kingston is offering faster all-round performance for file transfers on smartphones, quicker write times for microSD-wielding cameras and basically a few seconds of your life back -- at lower prices than before, though you'll still be paying a premium compared to slower cards. Our microSDHC-accepting devices are itching to hop aboard this speedier train of data storage, and luckily we won't have to wait long. The two memory cards start shipping at the end of March and are being offered with an available Mobility Kit, which includes an SD adapter and a USB card reader. But, if you want a full-fat 32GB model, you'll have to wait for Q2 of 2011 like the rest of us. Pricing starts at $22 for a 4GB model up to $138 for the 16GB model -- check after the break for full breakdown of prices and more in the PR.
