Bacteria Colonies May Be Linked By Nanowires [Science]

A bacterium on its own can't reach very far. And when stacked on the sea floor in a large colony, it may have access to either oxygen (top of the pile) or food (bottom of the pile).

So for the entire colony to thrive, the bottom and top layers must be choreographed in chemical reactions occurring across great expanses, allowing electrons from food consumption in the basement to react to oxygen from the rooftop.

A new study just published in Nature set to isolate the way bacteria pull of this stunt. The first guess, molecular diffusion, was found to be too slow for as dynamically as these colonies reacted in various testing. Now? It's believed the bacteria use interconnected nanowires, sharing electrons across expanses 20,000 times their individual size—though to be fair, there's no direct evidence proving the existence of said wires.

The implications for you, gadget lover? The possibility of one day using a really gross battery. [Nature via PopSci][Nanowire Image]

Desktop PC components get rated for power efficiency, Intel rules the roost

With all the antitrust noise, threats to AMD, and conflicts with NVIDIA, it's hard to feel too charmed with Intel at the moment. But, if you're looking for the best combination of performance and power consumption possible, you'll have to swallow any animosity and put an Intel inside, with an efficiency piece at bit-tech.net finding that chips from that manufacturer were, on average, considerably more efficient than their AMD counterparts. That's just part of the story, the site testing everything from memory to power supplies and finding the best compromise of performance and efficiency. It's perhaps no surprise that high-efficiency PSUs trump older, hotter ones, but you might not expect to learn that desktop SSDs offer barely any improvement over their 5,400RPM platter-based brethren. Follow the article's advice and you can shed 104 watts without losing a single 3DMark point -- though you may shed quite a few dollars in the process.

Steam Is Most Probably Coming to Macs [Unconfirmed]

If you're a Mac user, you may not know about Steam. By Valve (makers of Half-Life and L4D) it's the greatest game distribution service in existence—like an iTunes for PC games. Now, it could be coming to Macs.

In Steam's latest beta release, a search through its files revealed a number of OSX-specific assets, like a Steam dock icon (among loads of others). Since there's no reason for OSX resources—that I should add, are specifically labeled "OSX"—to make their way into a PC product, it seems pretty certain that, yes, Steam is coming to Mac. Hooray!

Now, with Steam imminent, all the Mac platform needs is the actual games! [Steam Forums via Kotaku, who crafted the excellent lead shot]

Honda shows off three-wheeled 3R-C concept vehicle

Dig the idea of something like GM's P.U.M.A. personal transporter but wish it would make you want to say pew pew pew whenever you're driving? Then feast your eyes on the Honda 3R-C concept that's just been announced in advance of the Geneva Motor Show. Nothing even approaching a roll-out date, as you might expect, but the three-wheeled vehicle would apparently use a battery electric drivetrain mounted low in the chassis for improved stability, and it even includes a bit of room for storage in the front, along with a clear canopy that apparently shifts to a windshield to give the "pilot" a bit more headroom. Not much else in the way of details, unfortunately, but Honda might have a bit more to say after its official unveiling in Geneva next week.

Pentax makes all-weather Optio W90 and superzoom X90 official

Source: http://www.engadget.com/2010/02/25/pentax-makes-all-weather-optio-w90-and-superzoom-x90-official/

Pentax is going for broke with its take on the rugged camera, the W90, which is unlikely to ever be confused for a svelte and stylish point-and-shoot. What it loses in looks, it gains in usability, however, as the 12.1 megapixel shooter can withstand shocks from a height of four feet, go nearly 20 feet under water, and withstand temperatures as slow as -10 degrees Celsius. The dustproofing is just topping on that rugged cake, though it still offers things like 720p / 30fps video recording and 5x optical zoom that are now considered standard camera specs. There are also three forms of shake reduction: one is post-processing of affected images, the second is by automatically increasing the ISO in low light conditions, and the third is the use of "exclusive software" during movie mode. We can't say any one of those will be as good as a well-implemented optical image stabilization, but at least they're there and might offer some assistance. As to the X90, it joins a growing band of 26x and above optical superzoomers, while adding the W90's 720p video mode and anti-shake plus its own sensor-shift stabilizer for good measure. Both shooters are expected in April, priced at $330 for the W90 and $400 for the X90, though we've noticed the former will show up a month earlier in the UK with a £270 ($417) price tag.
