NASA finds DNA components in meteorites, says they originated in space (video)

So, this is kinda wild: scientists at NASA have uncovered new evidence that DNA components found in meteorites can originate in space, lending new credence to the theory that life on Earth may have arisen from a pre-existing “kit” of materials delivered via asteroid. The discovery is outlined in a new paper from Dr. Michael Callahan, whose team of researchers closely analyzed samples from 12 different meteorites, using a mass spectrometer and liquid chromatography. In their samples, they found traces of adenine, guanine, and a variety of molecules known as nucleobase analogs — including three that are rarely found on Earth. Scientists have long known that meteorites can contain DNA elements, but were unsure whether these materials actually originate in space. The presence of these three molecules, however, suggest that they do, potentially raising new questions about the dawn of life on Earth, and beyond. It’s all quite heady, but steam ahead for a NASA video that might help clarify things, after the break.

The Earth Has a Ring

Of anti-protons! While it’s not as visually cool as what Saturn has going for it, this is still an important development, even if we can’t technically “see” the ring with our primitive Earthling eyes. More »

WhiteHat Security hacks into Chrome OS, exposes extension vulnerability at Black Hat

It’s been a rough Black Hat conference for Google. First, FusionX used the company’s homepage to pry into a host of SCADA systems, and now, a pair of experts have discovered a way to hack into Chrome OS. According to WhiteHat security researchers Matt Johansen and Kyle Osborn, one major issue is Google’s vet-free app approval process, which leaves its Chrome Web Store susceptible to malicious extensions. But there are also vulnerabilities within native extensions, like ScratchPad — a note-taking extension that stores data in Google Docs. Using a cross-site scripting injection, Johansen and Osborn were able to steal a user’s contacts and cookies, which could give hackers access to other accounts, including Gmail. Big G quickly patched the hole after WhiteHat uncovered it earlier this year, but researchers told Black Hat’s attendees that they’ve discovered similar vulnerabilities in other extensions, as well. In a statement, a Google spokesperson said, “This conversation is about the Web, not Chrome OS. Chromebooks raise security protections on computing hardware to new levels.” The company went on to say that its laptops can ward off attacks better than most, thanks to “a carefully designed extensions model and the advanced security available through Chrome that many users and experts have embraced.”

Bite Counter knows how many donuts you devoured, shames you into eating less

Because all you ever really wanted was an $800 bracelet that counts calories… enter the Bite Counter. It’s the retro-lookinlovechild of two Clemson University researchers that helps its hosts approximate caloric consumption by counting how many bites they take. Color us skeptical, as the meatbag wearing the gizmo has to — gasp! — actually remember to both start and stop the device each time they feast. The duo is hopeful it’ll glean useful data for future research, as the contraption can be used “anywhere, such as at restaurants or while working” — you know, places where scribbling how much you eat in a secret diary is frowned upon. Best of luck fellas, but until it hits a sub-century price point, we’ll just stick to eating salads. PR after the jump.

$1 chip tests for HIV in 15 minutes flat, fits in your wallet

Getting tested for STDs used to mean a doctor’s visit, vials of blood, and days, weeks, or even months of anxiously waiting for results. mChip aims to change all that, while simultaneously ridding your brain of viable excuses not to get tested. It works as such: one drop of blood goes on the microfluidics-based optical chip, 15 minutes pass, and boom, the AmEx-sized device will confirm whether or not you have syphilis and / or HIV. The bantam gizmo is practically foolproof, as reading the results doesn’t require any human interpretation whatsoever. Plus, it’s cheap — cheaper than a coffee at Starbucks. One dollar cheap. Researchers at Columbia University claim the mChip has a 100 percent detection rate, although there’s a four to six percent chance of getting a false positive — a stat similar to traditional lab tests. As you’d likely expect, there’s hope that the inexpensive mChip will help testing efforts in places like Africa to detect HIV before it turns into AIDS. Next stop: the self-service pharmacy at CVS?

Researchers use graphene and tin sandwich to make better battery electrodes

Graphene, that microscopic chicken wire made of carbon atoms, has a great many theoretical uses. Among these is to improve Lithium-ion battery technologies, and the big brains at the Lawrence Berkeley National Laboratory have created a graphene and tin composite material for use in battery electrodes. When it’s baked at 572 degrees Fahrenheit (300 degrees Celsius) the tin turns into nanopillars that widen the gap between the graphene layers. The greater volume of tin provided by these tiny towers improves electrode performance (read: faster charging), and the flexibility of the graphene prevents electrode degradation. Naturally, current prototypes can only maintain capacity over 30 charge cycles — as opposed to the hundreds required for commercial applications — so some serious improvement has to happen before we see it strut its stuff in any phones or EVs. This leaves us, once again, extolling the virtues of graphene, but lamenting its exclusively academic application.

OutRun AR project lets you game and drive at the same time, makes us drool

Cool game, or coolest game ever? That’s the question we were asking ourselves when we first came across Garnet Hertz’s augmented reality-based OutRun project — a concept car that weds Sega’s classic driving game with an electric golf cart, allowing players to navigate their way around real-life courses using only arcade consoles. Hertz, an informatics researcher at the University of California Irvine, has since brought his idea to fruition, after outfitting the system with cameras and customized software that can “look” in front of the car to automatically reproduce the route on the game cabin’s screen. The map is displayed in the same 8-bit rendering you’d see on the original OutRun, with perspectives changing proportionally to shifts in steering. The cart maxes out at only 13 mph, though speed isn’t really the idea; Hertz and his colleagues hope their technology can be used to develop game-based therapies for disabled users, or to create similarly AR-based wheelchairs. Scoot past the break to see a video of the car in action, and let your dreams converge.

FCC measures US wireline advertised broadband speeds, fiber dominates cable and DSL

Ever wonder if the speeds your ISP advertises are actually what you’re getting while reloading Engadget all day? The FCC did, and decided to team up with 13 major broadband providers in the US to test how they performed from February to June of this year. Notably, during peak hours the average continuous download speeds of fiber connections were 14 percent faster than advertised, while cable and DSL were slower than claimed by 8 and 18 percent, respectively. Upload speeds also varied, with DSL again dipping the lowest at 95-percent of what’s advertised — might be time to ask your phone-based ISP for a partial refund, no? In addition to sustained speeds, the FCC analyzed consumer connections’ latency and the effect of ISP speed boost tech on activities like VoIP, gaming, and video streaming.

In concluding its research, the Commission noted that it should be easy to get tools in users’ hands for keeping better tabs on ISP-provided services, without needing to contact customer frustrations relations. The study is chock full of even more graphs and stats, which you’ll find by hitting that source link below. Now, if only we could get those speeds on par with our friends across the Atlantic.

AMD’s market share tiptoes higher, Intel still ruler of the roost

Intel may still be king of the microprocessing hill, but from the looks of IDC’s latest market report, scrappy underdog AMD is starting to claim more of the $9.5 billion dollar pie. The semiconductor stalwarts faced off in four separate market categories with runner-up AMD seeing gains in all, save for servers where its paltry 5.5 percent share dropped 0.6 percent versus Intel’s commanding 94.5 percent lead. The Q2 2011 report pegged Intel’s overall worldwide share at 79.3 percent, a 1.5 percent decrease from the previous quarter, while AMD saw a 1.5 percent increase to 20.4 percent. For the mobile PC realm, Intel once again saw a decline as its 84.4 percent share took a 1.9 percent quarter to quarter tumble, with AMD again seeing a nearly 2 percent gain in its 15.2 percent stake. In the desktop PC segment, AMD grabbed an additional 1.5 percent, bringing its stake to 28.9 percent, with Intel’s 70.9 percent share dropping 1.5 percent versus Q1 2011. Wondering where the second place chip maker got its second quarter stride? According to the research firm, its new Fusion platform, along with Intel’s Sandy Bridge, now accounts for “more than 60% of total PC processor unit volume in 2Q11.” You paying attention, Sandy? It’s time to sleep with one eye open.
