MIT’s genetically modified viruses boost solar-cell efficiency by herding nanotubes

The wizards of MIT have done it again. Having checked artificial leaves and Operabots off the to-do list, they’ve moved on to improving the efficiency of solar cells. Their technique combines a genetically modified version of the M13 virus with carbon nanotubes, which have already been shown to increase efficiency. Unfortunately, some nanotubes enhance solar cell performance, while others inhibit it – and both types tend to clump together, negating their benefits. The modified M13 virus, however, can separate the two types as well as prevent clumping; we’ve seen similar use of the Tobacco mosaic virus to build better electrodes. Adding virus-built structures to dye-sensitized solar cells increased power conversion efficiency by almost one-third and, with only one additional step in the manufacturing process required, the new approach could be rapidly taken up by existing production facilities. MIT: proving once again that viruses are good for more than just smiting your enemies.

Motorola Plans More Hacker-Friendly Phones

Since the premiere of the Droid Two, Motorola’s Android-based smartphones have been notoriously unfriendly to modification and hacking. But the company may be changing its ways.

According to Motorola, its devices will become more mod-friendly toward the end of this year. The company plans to introduce software changes which will allow advanced users the option to modify core components of their phone’s operating system.

“Motorola will enable an unlockable/relockable bootloader, currently found on Motorola Xoom, in future software releases where carrier and operator partners will allow it,” Motorola said in a statement provided to Wired.com. “It is our intention to include the unlockable/relockable bootloader in software releases starting in late 2011.”

A locked bootloader is a big irritation for people who want to modify their Android phones’ operating systems. In short, it drastically limits the amount and type of customization a customer can accomplish on his or her phone. Popular modding software like CyanogenMod — a custom Android build that optimizes a phone’s hardware performance and adds a number of nifty flourishes — can’t be installed.

Motorola contends that it wants to strike a balance between “the operator requirement for security to the end user” or the average Joe with an Android device who doesn’t care about hacking it, one the one hand, and “the need to support developer communities in using these products as a development platform,” on the other. The option to unlock and relock the bootloader on a phone seems to fit in this middle ground, though Motorola does say this will be restricted to “the carrier and operator partners” that will allow the option.

The company hasn’t always been so diplomatic. When people complained about Motorola’s locked-down practices in the comments section of a YouTube video featuring the Atrix earlier this year, a Motorola employee shot back a less-than-warm response:

“If you want to do custom roms [i.e. modification software], then buy elsewhere, we’ll continue with our strategy that is working thanks.”

After developer uproar ensued in the wake of the comment, Motorola apologized, and gave its first sign that the locked-down quality of its phones may soon change:

“We apologize for the feedback we provided regarding our bootloader policy. The response does not reflect the views of Motorola. We are working closely with our partners to offer a bootloader solution that will enable developers to use our devices as a development platform while still protecting our users’ interests.”

Not everyone in the developer community is convinced Motorola will change its ways. Just as with the Atrix, they say they’ve been burned before. The Droid Two and Droid X models, for example, both came with locked bootloaders, despite the immense success of the Droid One.

When Android user Irwin Proud decided to buy the Atrix smartphone in February, he assumed it would ship with an unlocked bootloader.

He assumed wrong. Proud received an Atrix with a locked bootloader. As a self-proclaimed tech nerd and phone-modification enthusiast with a locked-down phone, Proud wasn’t happy.

Instead of taking it lying down, he started an online petition in late March at Groubal.com, asking Motorola to provide an unlocked bootloader solution for its current and upcoming devices. As of Wednesday, Proud’s petition has close to 9,000 signatures.

After a series of back-and-forth e-mails between Proud and customer-service representatives at Motorola, the company finally issued a statement to Proud claiming that an unlockable bootloader would be made available to its late 2011 releases.

Proud remains hopeful. “I’m optimistic that they will change,” said Proud in an interview with Wired.com, “because they have not experienced the same level of interest for any of their devices since the original Droid phone released at the end of 2009.”

Indeed, exact sales figures for the Atrix and the Xoom haven’t been released, but some analysts are calling projections “disappointing.”

“I think they’ve tried to replicate it’s success,” said Proud, “but they haven’t had any luck. Now they need their community back.”


Nokia Slashes 4000 Jobs Worldwide

Nokia Logo

We all knew it was coming: when Nokia and Microsoft signed their agreement to bring Windows Phone 7 to Nokia handsets, the end was nigh for Symbian – and all of the developers, engineers, and support staff that Nokia had built up around the flagging mobile OS. Now, Nokia has made good on the bad news and served over 4,000 employees worldwide with pink slips. 
In addition to letting that staff go, Nokia is divesting itself of Symbian entirely, and handing it off to Accenture, another technology firm that’s agreed to take Symbian support and development off of Nokia’s hands. Accenture in turn will then become the “preferred provider” of software and services for Nokia’s handsets – including the upcoming Windows Phone 7 devices. 
Nokia may have just fired 4,000 people, but they are offering many of them the opportunity to re-apply for other jobs at the company and get job training for roles elsewhere. Look on the bright side guys, Google still says they’re hiring

Rumor: Hulu Plus to Land on Xbox Live on April 29

Hulu Plus Logo

For those people who use their Xbox 360 are a primary form of both gaming entertainment and video entertainment, it might be finally time to invest in a Hulu Plus account. According to a post at Joystiq, Hulu Plus will arrive on the Xbox 360 on April 29th, finally ending the long wait that Xbox owners have had to suffer while PS3 owners gloated in their faces. 
The Xbox 360 has only had Netflix up to this point, but PS3 owners have had both Netflix and Hulu Plus access. That difference has made people looking to cancel their cable television in exchange for streaming video on the Web look more carefully at the PS3 than the Xbox 360. If the story is true and Hulu Plus does come to the Xbox 360 this week, it would put the two consoles back on even ground.

Google Docs gets an Android app, we go hands-on with tiny spreadsheets (video)

Staring at spreadsheets crushed down to unreadable sizes on a 4-inch phone screen is far from pleasurable but, clearly there is a demand. In fact, we’ve been clamoring for a proper Google Docs app for ages, even though sometimes we’re not entirely sure why. It was only a matter of time before Google finally got around to appeasing us mobile workaholics and put an official app in the Android Market. Well, our masochistic prayers were answered — the Mighty Goog unleashed the new, native Google Docs for Android app and we rushed on over to the Market, clicked the install button, and gave it a whirl.

Google Android Video: Quake & Street View

This article was written on March 03, 2008 by CyberNet.

The Google Android mobile operating system will likely take the mobile industry by storm when it is released. From what I’ve read they are already lining up handset manufacturers who want to run Android when it becomes publicly available, and it’s expected to be available on around a dozen different handsets running it when launched later this year.

The demonstrations last month at Mobile World Congress for Android were less than stellar, and didn’t really show off anything that would leave an impression in your mind. Not to mention that there was no touch screen action thrown in the mix. What Google demonstrated last year was a lot more exciting than those, but even still they didn’t really tinker with the capabilities of the system.

BBC got the chance to meet with Andy Rubin, the main guy behind Android, who was kind enough to show first hand some of the things that can be done on a 300MHz touch screen device (half the speed of the iPhone). I’ve embedded the video below, and here’s an overview of what happens so that you can skip around to the parts that interest you:

  • 43 seconds: Webkit-based browser demonstration. Shows panning and zooming around websites, and they make a point to say that it is using the 3G network which the iPhone currently lacks.
  • 2 minutes 22 seconds: Non-interactive Quake demonstration showing off the 3D capabilities. Looks rather good from the video, but I wonder if it would look the same if a user was actually playing the game.
  • 2 minutes 50 seconds: A Google Street View application is demonstrated. When watching this I thought about how cool it would be if Google tied this into a GPS receiver!

I really like where Android is headed, and the fact that an SDK is widely available to developers will probably make this grow very quickly. We’ll have to see what Apple unveils this week for the iPhone SDK before we make any judgements and comparisons.

Nikon’s D5100 impresses, captures children’s birthday parties with incredible clarity

Nikon D5100

We’re not the only site to put Nikon’s new mid-range DSLR through its paces. Plenty of others have taken the D5100 for a spin and we thought you might like to know: they’re all pretty impressed. The new 1080p30 video mode was much appreciated as was the larger, higher resolution swivel screen around back. The biggest props generally went to the improved high-ISO performance (which was already quite respectable on the D5000 it’s replacing) and the boost in autofocus speed, especially when using the LCD as a view finder in Live View mode. Oddly, the built-in effects also garnered a lot of attention. The Miniature Effect (a tilt-shift simulator) and Selective Color mode impressed reviewers the most with their surprising level of sophistication for in-camera processing. All of the effects can also be used when shooting video, so you can make your HD footage look like black and white 8mm by turning on Night Vision. Criticisms were relatively minor and applicable to most mid- and entry-level DSLRs — primarily that the body is plasticy and there is a slight lag in focus and shutter performance. The D5100 is an obvious upgrade over the D5000 and more than holds its own against its competitors, but if you want to dig deeper check out our review and the ones below.
