Who Needs DNA? Prions Evolve Without It | 80beats

prionsFor evolution to take place, you need DNA or RNA to change through mutation, providing the variations for natural selection to select. Right? Well, it may be more complicated than that. A new study suggests an exception: prions, the infectious protein bits that can cause degenerative brain diseases like mad cow disease. In a paper in Science, researchers document these lifeless structures evolving, despite the fact that they lack any DNA or RNA.

Study leader Charles Weissmann and his team transferred prions from brain cells to other kinds of cells and watched as certain members of the prion population adapted to the new environment and took over, out-competing their brethren. When he transferred the prions back to brain cells, the ones most adapted to brain living got the upper hand and increased in number as they out-competed the prions that had adapted to other cells. Weissmann argues that this shows Darwinian evolution can go even further than we thought: “In viruses, mutation is linked to changes in nucleic acid sequence that leads to resistance. Now, this adaptability has moved one level down- to prions and protein folding – and it’s clear that you do not need nucleic acid (DNA or RNA) for the process of evolution” [BBC News].

In diseases like mad cow and the human version of it, Creutzfeldt-Jakob disease, proteins in the brain go awry. Mammals produce the normal protein cousins of infectious prions as part of normal cell development, but during infection, misfolded or warped proteins can convert normal host prion protein into its own toxic, misfolded form. When this happens enough times, massive tissue and cell damage can occur [Popular Science].

This pattern of warping proteins could be the key to how this DNA-less evolution occurs, the researchers propose. When a prion converts a normal protein, it typically forces it into the same structure as itself, but at a low probability, other variant structures result. The population of these variants can then expand or contract based on selective pressures [Ars Technica]. This appears to happen more quickly when the prions are transferred to a new host, as happened in previous research when scientists moved prions from sheep to mice—the more virulent variants got a chance to take hold.

Given the problems today with bacteria and viruses evolving drug resistance, the idea of evolving prions seems like more bad news. But, taking a note from DISCOVER blogger Carl Zimmer’s “Evolving Viruses to Death,” perhaps doctors could use prions’ strength against them: Since infectious prions need their normal cousins to feed their own replication and evolution, therapies that limit the supply of normal prion proteins could essentially starve the degenerative cycle that makes those illnesses so effective at killing their hosts [Popular Science].

Light Writing Proposal Created With Two Canon 7Ds, a Spotlight and a Lot of Love [Cameras]

Well now, this certainly puts my fiance's restaurant proposal to shame. Boy Derick proposed to girl Emily using a spotlight, DSLR and three nights, creating a spectacular light writing proposal.

Along with several friends, two Canon 7D cameras were used by Derick to create the proposal—one on the ground, one from a hotel room looking out across the scene—with the ground camera using a Nikon 50mm f/1.4 lens. Dragon Stop Motion was used to superimpose the light writing image over the live view from the ground camera, with the video shown a few days later to the happy Emily.

Pico Projector From Light Blue Optics Throws Up a 10-inch Touchscreen Laser Projection [Projector]

Light Blue Optics has been showing off their cool projection wares since 2004, so it's great to hear they're close to turning that "holographic laser projection technology" into a viable product, albeit as an OEM.

The Light Touch pico projector throws a laser WVGA image out to the size of 10-inches, turning any available surface into a touchscreen. The angle is a pretty decent wide throw, which means the projector can be quite close to the surface.

Running on Adobe Flash Lite 3.1, the Light Touch projector has 2GB of flash memory and a microSD card slot (with support up to 32GB) for storing media on, and also has Wi-Fi and Bluetooth for hooking up with a laptop or device. It supposedly has a 2 hour battery life, which unfortunately seems to be the norm with these little projectors, though kudos to Light Blue Optics for throwing in a bunch of other features that could make this actually useful, for consumers as well as businesses (as the pic below shows).

Social Network for Beautiful People Kicks Out 5,000 “Fatties” | Discoblog

beautiful-people-webThe elite online dating club BeautifulPeople.com (yes, this is a real Web site), trimmed 5,000 members from its service because they appear to have indulged in too much Christmas ham.

Feast your eyes on this excerpt from the company’s statement, via CNN:

“As a business, we mourn the loss of any member, but the fact remains that our members demand the high standard of beauty be upheld,” said Robert Hintze, founder of BeautifulPeople.com. “Letting fatties roam the site is a direct threat to our business model and the very concept for which BeautifulPeople.com was founded.”

Publicity stunt? Probably. Shocking? Hardly. When vain folks sign up for a service so they can be rated by a group of narcissistic pretty people this is bound to happen.

If you’re one of the expelled 5,000, don’t let this get you down. The company says you’re welcome to reapply—after the love handles are gone, of course.

What Is This? [Imagecache]

Hint: it's not from space and it's not from inside your body. But it does represent something you're totally reliant on.

It's an electrograph of a brass wire gauge, made in 1900 to help show the wary public that electricity didn't come in just the form of tree-felling and fire-starting lightning. Scientists needed to prove that it was a safe thing to allow into their homes, and that involved visualizing electromagnetic waves in a way that the public could understand. This was one of the ways they did it. It just happens to look pretty awesome. [Wired; Photo courtesy San Francisco Museum of Modern Art]



Loss | Cosmic Variance

I am heartbroken to learn the loss of a member of the physics community in the recent avalanche in Switzerland. I have few details, but it appears that Thomas Binoth was killed in the avalanche, and that at least two other physicists and astrophysicists from the party have been hospitalized. Many others were lost, including some of the rescuers, who were swept up in a second avalanche.

Condolences to all who have been affected by this tragedy.


Nvidia Optimus the Secret to the New MacBook Guts? [Notebooks]

Nvidia's teasing a new notebook tech called Optimus that "get[s] the performance of discrete graphics from a notebook while still delivering great battery life." Which could solve the mystery of the next MacBook guts.

A brief recap: Intel's new Arrandale Core i5 processors for notebooks have integrated graphics built right into the chip, but they suck, and Nvidia's chipsets with superior integrated graphics, like the current MacBooks have, are incompatible with all of Intel's new chips. So if refreshed MacBooks were to use Intel's integrated graphics, they'd have worse graphics than the current models.

The top-end MacBook Pros have switchable graphics and have had them since the unibody debuted—integrated GeForce 9400M to save battery life, discrete GeForce 9600 GT for more power. Nvidia's Optimus, if it's good, seems to open a door for Apple to use straight-up discrete graphics, like older MacBook Pros (and even PowerBooks), without seriously harming the massive battery life that's a big part of the current MacBook Pros—maintaining graphics performance and battery life without some kind of custom hardware arrangement.

And it wouldn't be the first time Nvidia's debuted new tech with Apple, since that was exactly the case with the GeForce 9400M chipset/graphics that's in almost all of Apple's current machines, which you might also know as Ion, Nvidia's better-graphics-for-netbooks chip.

My guess is that it's simply scalable performance, trading off battery and performance as efficiently as possible. Guess we'll see, and know more, in about a month, according to Nvidia. [Nvidia]



iRiver Story Ereader Hits US Shores This Month; Pricing Still a Terrifying Mystery [IRiver]

iRiver's Story eReader has taken its sweet time making a stateside appearance, and as of today, it's still not here. But it's coming! Sometime in January, to be "specific." But will it be as comically expensive as its European counterpart?

Hopefully, no. But probably? Yes. The Story has reviewed fairly well, with testers citing attractive (if obviously derivative) industrial design, ePub support and a decent screen among its strengths, but with a sky-high price tag—the equivalent to $320—more or less pulling it out of the running, especially when cheaper reader like the Kindle and Nook come with 3G and Wi-Fi, the former being excluded on the Story, and the latter not making an appearance until "early Q2," possibly at a premium.

In other words, iRiver: you need to make this thing cheaper, or else it will drown. Ok! [iRiver]



The Viliv N5 Netbook Is One Tiny Step Up From a Smartphone [NetBooks]

The Viliv n5 touchscreen netbook looks a lot like the Vaio P, but let's hope it's not priced like one. Either way, I don't see much of an advantage here over a traditional smartphone.

I mean, it may not be touchscreen like the 4.8-inch Viliv display, but the 8-inch screen on the Vaio P does a little more to distinguish it from a smartphone. Other Viliv features include: an Intel Atom Z520 1.3GHz processor (Windows 7 Home Premium), 32GB of SSD storage, GPS, a 1.3 megapixel webcam, Bluetooth, WiFi and a microSD memory card slot. Personally, I think their upcoming 10-inch Blade netbook tablet looks more promising, although Viliv has been disappointing in the past. [UMPC Portal via Ubergizmo]

Apple Dabbles With a 3D Multitouch UI [Apple]

A recently released patent by Apple shows that they are one of several companies dabbling with the idea of a 3D mulitouch interface. In this case, a "touch screen device, method and graphical user interface for manipulating three-dimensional virtual objects."

Will we see this sort of technology on upcoming Apple products like the tablet? Probably not, but it is interesting to point out that Apple went to some lengths to "disguise" the patent under the names of three obscure French employees. That might be business as usual for Apple, but it could also mean that they are serious about moving beyond standard pinching and zooming. [Baltimore Sun]

Except, that is, the price: Initial reports had it pegged at $200; now a needlessly cryptic press release puts it "under $200."

In other news! The Boxee Box is otherwise exactly was we know it to be, and it's still on track for a "H1 2010" release. Spec porn, albeit a bit rehashed:

Networking Pioneer and Popular Entertainment Software Create the Best Way to Get the Free Entertainment the Internet Has to Offer With No Monthly Fee

Black and White and Blue All Over | Cosmic Variance

By now a lot of people have seen James Cameron’s Avatar, and a much larger number have formed an opinion about it. Anticipation had been building for months, as people were excited by the prospect that ultra-realistic computer animation would combine with dazzling 3D technology to produce a different kind of movie than anyone had ever seen.

It’s generally not a good sign when the buzz is about the technology behind a movie rather than the story within it, and in the case of Avatar the worries are justified. There’s no question that the moviemaking is truly impressive; not only is it a great technological achievement, but Cameron is an accomplished storyteller. The film is long but never ponderous, the set pieces are thrilling, and one’s heartstrings are tugged at all the right places. As a bonus, the acting is fantastic — Sigourney Weaver’s gruff scientist in particular is a great character.

Alas, in a world that one would like to see fleshed out in shades of gray, Cameron’s contrast knob is stuck resolutely at eleven. (Spoilers henceforth.) Humans have destroyed their own planet, and are now descending on Pandora to set about destroying that. The bad guys are represented by a craven businessman and a scarred ex-Marine. War and capitalism are bad! We get it.

But cartoonish villains don’t necessarily spell doom for a movie, especially one meant to be an elaborate thrill ride. I didn’t leave Raiders of the Lost Ark wishing that the Nazis had been more fleshed-out, and nobody gives thanks that the Star Wars prequels let us in on Darth Vader’s backstory. The problem arises when such banal evil is trotted out in service of A MESSAGE. And if there’s one thing Avatar has, it’s a message — a particularly trite one, which is deeply misguided, but a message nonetheless.

The Na’vi, Pandora’s native race, are presented very bluntly as traditional noble savages. They may be nine feet tall and blue, and find themselves trapped in a series of Yes album covers, but that just provides a convenient excuse to mix and match features of Native Americans and African tribes as the director sees fit. The Na’vi are portrayed as saintly tree-huggers who feel bad when jungle beasts are killed unnecessarily; at any moment you expected to hear “This animal is called the bufa’lo. We use every part of it.”

To drive things home, most of the humans are portrayed by white actors, while most of the actors behind the motion-captured Na’vi are people of color. And to drive things home even more (things worth driving home can never be driven too much, right?), the Na’vi have a literal connection with the natural world around them. Which might be a cool idea worth exploring, if it weren’t deployed as a gimmick to emphasize the pastoral purity of the pre-technological natives. (I can’t wait for Oscar night: “We would like to express our gratitude for all these Academy Awards for technical achievement given to our movie about how true virtue is to be found in wearing loincloths and chanting around trees.”)

avatar

And even that wouldn’t be so bad, if the noble savages weren’t portrayed as good-hearted but ineffectual. Eventually they manage to fight off the invading Earthlings, who despite mastering interstellar travel and consciousness-transferal are still stuck using machine guns and tiny rockets when hostilities break out. But they’re only able to do so because the kind-hearted white warrior rides to their rescue. Sam Worthington’s character, the protagonist with whom we are supposed to identify, spends three months as a Na’vi and turns out to be better at it than any of the primitive sods who were actually born that way. Only he is able to tame the legendary beast, bring far-flung tribes together to work for a common cause, and have the wit to appeal to the ecosystem-network for a bit of help.

It’s an old trope, fueled by liberal guilt. “Sure,” the elaborate narrative rationalization goes, “people like me have screwed over people like you for generations. But I’m pretty sure that, had I been around at the time, I would have been one of the shining exceptions who bravely turned against my compatriots to side with the honorable native folk. Who, frankly, could have used my help.” It’s the victors who tell the stories and make the movies.

How one reacts to Avatar depends strongly on how bothered one is by this kind of stereotypically condescending storyline. As a thrilling popcorn movie, it absolutely works; the detailed world Cameron created is breathtaking; and the technological feat is singularly impressive. But when these achievements are in the service of a message that is so ham-handed and ultimately off-putting, I find it hard to enjoy. If the storytelling had been handled with a little more self-awareness and toleration for ambiguity — by the folks at Pixar, for example — it might really have been an historically good movie.


Vizio XVT Pro 3D HDTVs Are Stacked for Cheaper: Local Dimming, 480Hz and Wireless HDMI [TVs]

Vizio's flagship XVT Pro 3D HDTVs way undercut the top-o-the-line LED TVs from the other guys: 480Hz, wireless HDMI, Wi-Fi, local-dimming LED backlight and 3D. The 72 inch set goes for $3500, cheaper than the 46-inchers from Sony or Samsung.

The 55-incher set is $2500, and and the 47-inch TV is $2000. The main diff between them is that the 72-inch has more zones for local dimming—480 to 120 and 180 in the smaller sets—and the smaller sets have an anti-reflective coating. They're all out in August.

LAS VEGAS, NV (CES) and IRVINE, CA – January 05, 2010 — VIZIO, America's #1 LCD HDTV Company, has unveiled their new high-performance XVT Pro Series of 480Hz SPS™ 16x9 TruLED™ Full HD3D™HDTVs available in 72", 55" and 47" sizes, as well as a 58" Cinema Wide HDTV that displays content in 21 x 9 aspect ratio.

"50% of consumers want a 3D home theater, according to Quixel Research, and our new XVT Pro Series brings the latest technology to consumers who want the absolute BEST in class."

Defining state of the art performance, these VIZIO 72", 55" and 47" Full HD3D™ TVs advance refresh rates to 480Hz SPS™ with VIZIO's Smooth Motion™ technology. Their TruLED™ brilliant LEDs pervade the entire display (Under 3" profile) and have Smart Dimming™ circuitry that controls hundreds of zones of LEDs per screen to the precise light level per picture frame in 480, 120 and 160 zones, respectively.

For environments with bright ambient lighting, the 55" and 47" models feature a unique anti-reflective panel that produces better contrast with rich and deep blacks even in brightly lit rooms.

FULL HD3D™
Utilizing SENSIO® 3D technology to deliver 3D content over conventional 2D infrastructure, the new VIZIO XVT Pro Full HD3D TVs display stunning 3D content that the user can view with XpanD active-shutter glasses (sold separately). Unlike other 3D TVs that use passive stereoscopic imaging, VIZIO's Full HD3D TVs can display full 1080p video to each eye by rapidly alternating between the left-eye and right-eye images within the same visual space. The special active-shutter glasses, which communicate with the television over Bluetooth, then transform each lens from opaque to transparent in perfect synchronization with the images displayed on the TV, which allows for delivery of the full frame rate capable by the television for the ultimate 3D HDTV viewing experience.

These sets can produce 3D images from SENSIO encoded material on conventional DVD and Blu-ray players, as well as from future distribution channels such as pay per view, video on demand, DTV and HDTV broadcasts.

"We are pleased to be working closely with VIZIO and be a part of the creation of a substantial install-base of consumers ready to watch 3D movies, live concerts, and sporting events from the comfort of their home," states Nicholas Routhier, President and Chief Executive Officer of SENSIO Technologies.

"We are excited to partner with VIZIO as catalysts in the 3D revolution for the home," said Maria Costeira, CEO of XpanD. "The combination of XpanD Cinema active-shutter glasses and Vizio displays will provide an immersive, dynamic and cost-effective solution for VIZIO XVT Pro owners."

Wireless HDMI
Eliminating the need for an HDMI cable from source components to the display, the 72", 55" and 47" XVT Pro Series have an integrated Wireless HDMI receiver built-in, using SiBEAM's robust 60 GHz technology to receive HD content from high definition sources such as Blu-ray players or set-top boxes with full HD 1080p resolution when paired with a separately available VIZIO XVT Pro Wireless HDMI Adapter. The XVT Pro Adapter supports up to 4 HDMI sources and operates at 60GHz to avoid interference with other wireless devices in the home like cordless telephones and wireless networks that operate at 2.4 and 5 GHz.

SRS StudioSound HD
VIZIO XVT Pro TVs will feature SRS StudioSound HD - the ultimate all-in-one audio suite designed specifically for Flat Panel TVs. Years of excellence in audio, practical experience and patented technologies allow StudioSound HD to deliver the most immersive and natural surround sound ever using built-in TV speakers. The suite also delivers remarkably crisp and clear dialog, rich bass, an elevated sound stage and consistent, spike-free volume levels. StudioSound HD features optimized audio presets for movies, news, sports and music while also providing a built-in EQ toolset for peak audio performance.

VIZIO INTERNET APPS™ (VIA)
All of the XVT Pro sets feature the VIZIO INTERNET APPS™ (VIA) Connected HDTV platform, delivering unprecedented choice and control of web-based content directly to the television without the need of a PC or set-top box. Able to connect to the Internet using the built-in high definition wireless (802.11n dual-band) or a wired connection, accessing on demand movies, TV episodes, music and other online content is easy, using the included Bluetooth universal remote control with sliding QWERTY keyboard that makes thumb-typing easy.
