Apple Updating iOS To Address Privacy Concerns

wiredmikey writes “[Apple] said that over the next few weeks it would release a software update for iOS that would reduce the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone, cease backing up the cache, and delete the cache entirely when Location Services is turned off. Additionally, Apple said that in the next major iOS software release the cache would be encrypted on the iPhone, though a timeline for that was not provided.”

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.

The Matrix Dance

I’m not normally one for choreographed dance routines, however if you check out Razy Gogonea’s performance on Britain’s Got Talent, I think you will agree this one is pretty sweet. Skip to about 1:30 in the video to see his recreations of iconic scenes from The Matrix that put Keanu Reeves slow motion bullet dodging moves to shame. Link

Notion Ink Adam review

The saga of the Notion Ink Adam is a tale like many we could name — it’s the story of a tiny company struggling to bring a vision to market, facing friction from investors, factories and the march of time itself. The difference is that the Adam captured the imaginations of gadget fiends like ourselves with ideas that were fantastic from day one and are still novel now that it’s finally been released, including a paneled UI, full USB host functionality, and of course that Pixel Qi screen. But does the Adam deliver on the promises of unifying form and function with such technology? In two words: Not really.
