Unique proteins in these amphibians cast doubt on the existence of any latent potential for limb regeneration
The Eastern, or red-spotted, newt may have evolved the ability to regenerate organs and limbs in relatively recent times Image: Flickr/StoneHorse Studios
The ability of some animals to regenerate tissue is generally considered to be an ancient quality of all multicellular animals. A genetic analysis of newts, however, now suggests that it evolved much more recently.
Tiny and delicate it may be, but the red spotted newt (Notophthalmus viridescens) has tissue-engineering skills that far surpass the most advanced biotechnology labs. The newt can regenerate lost tissue, including heart muscle, components of its central nervous system and even the lens of its eye.
Doctors hope that this skill relies on a basic genetic program that is common ? albeit often in latent form ? to all animals, including mammals, so that they can harness it in regenerative medicine. Mice, for instance, are able to generate new heart cells after myocardial injury.
The newt study, by Thomas Braun at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany, and his colleagues, suggest that it might not be so simple.
Attempts to analyze the genetics of newts in the same way as for humans, mice and flies have so far been hampered by the enormous size of the newt genome, which is ten times larger than our own. Braun and his colleagues therefore looked at the RNA produced when genes are expressed ? known as the transcriptome ? and used three analytical techniques to compile their data.
The team compiled the first catalogue of all the RNA transcripts expressed in N. viridescens, looking at both primary and regenerated tissue in the heart, limbs and eyes of both embryos and larvae.
The researchers found more than 120,000 RNA transcripts, of which they estimate 15,000 code for proteins. Of those, 826 were unique to the newt. What is more, several of those sequences were expressed at different levels in regenerated tissue than in primary tissue. Their results are published in Genome Biology.
Modern or ancestral?
The findings add to existing evidence that the ability evolved recently, says Jeremy Brockes of University College London, whose research provided the first evidence that regenerating tissue in salamanders express proteins that are not found in other vertebrates.
?I no longer believe that there is an ancestral program that is waiting to be reawakened,? Brockes says. ?However, I absolutely do believe it?s possible to coax mammal tissues into regenerating to a greater degree with the lessons we learn from newts.?
But saying that the trait is either ancestral or recent is probably too ?black and white?, says Elly Tanaka of the Center for Regenerative Therapies in Dresden, Germany. The truth, she says, could be somewhere in the middle. ?It may in fact be that regeneration is ancestral, but that newts have species-specific adaptations that allow it to have such spectacular regenerative capacities compared with other vertebrates.?
Moreover, Tanaka adds, scientists would do well to look for more grey zones in the potential for harnessing the regenerative capacities of newts (and of other animals, such as fish). Rather than focusing on spectacular, but perhaps unlikely, scenarios in which amputees could regrow entire limbs, researchers should instead focus on more plausible options, such as improving the healing of scars and burns or increasing the speed of organ regeneration.

We live in a world where we have beaten most diseases and already live longer than we should
Oh yeah... beaten most disease? Give me a fucking break. We certainly nailed some big viruses, but those aren't diseases.
Let me know when you figure out how to cure something as simple as Migraine headaches. How about depression, we have 'treatments' but certainly no cures, and those treatments are a crapshoot. Maybe this drug works... oh no, well lets try this one... Yeah it works, but your heartrate doubled...
The simple fact of the matter is that the current state of 'medicine' is that your options for actually beating a disease are:
1. Take a vaccine for the cause before you actually get the disease (if a vaccine exists)
2. Take antibiotics if it is bacterial in nature. Hope that the infection hasn't caused irreversable damage
3. Take a knife and cut it out.
4. Sew it back up.
Everything else is basically palliative care. We are just now beginning to se the barest glimpse of genetic treatments, and you are considering most diseases beaten and that people live too long?

(Reuters) - "Star Trek" star William Shatner and tens of thousands of the show's fans are leading a charge to name one of Pluto's newly discovered moons after the character Spock's home planet.
Shatner, who played Captain James T. Kirk on the Starship Enterprise on the program launched in 1966, proposed the name earlier this month in response to an appeal from scientists for help in choosing the names of two newly discovered Pluto moons.
Vulcan is among 21 names in the running in an online poll organized by the California-based SETI Institute, whose team of astronomers discovered the moons.
As of Wednesday, Vulcan was the clear front runner, receiving more than 100,000 out of more than 330,000 votes cast.
Shatner, who starred along with Leonard Nimoy, who portrayed the Vulcan science officer Spock on the long-running TV sci-fi show, rallied support for Vulcan on Wednesday on his Twitter account, writing: "We are approaching 120K votes for Vulcan on PlutoRocks.com! Have you voted today?"
Until now, the two moons, each of which are about 15 miles to 20 miles wide, have been known as P4 and P5. The P4 moon was discovered in 2011 and P5 a year later.
Before the discoveries, astronomers had identified and named three of Pluto's moons - Charon, Nix and Hydra.
Voting for the names of the new moons ends on February 25. The selected names will be submitted to the International Astronomical Union (IAU) for consideration.
"Let's hope the IAU thinks Vulcan is a good name," Shatner said in another tweet.

SPOKANE, Wash. -- A young bone cancer patient from Cheney now has a new battle to fight.
Doctors diagnosed Sierra Higbee with bone cancer in March 2012. She has undergone nine months of chemotherapy and multiple surgeries, including a partial amputation of her leg.
Two weeks after her final chemo treatment in December, Sierra had a seizure. It was a tumor in the back of her brain that caused it.
We?ll have more with Sierra's family tonight on KREM 2 News at 5.

For the four years I've been presenting at SFWC, I've always found the organizers enthusiastic and open-minded about self-publishing, but this year's conference took that enthusiasm to a new level. Multiple self-publishing keynotes and presentations from the likes of Guy Kawasaki, Bella Andre and even presentations from yours truly (embedded below!) helped educate newbie and experienced authors alike on how to advance their writing careers.
The vibe at SFWC is always positive, a top-down attitude that emanates directly from the amazing organizers Michael and Elizabeth Pomada, as well as a team of dozens of hard-working and enthusiastic volunteers.? Speaking with organizers it was apparent that the vibe for this, the 10th Anniversay of the conference, was the most positive ever.?
The reason?? Self-publishing.? Self-publishing took front and center stage this year.? Writers left the conference confident that one way or another, their books will be published and available to readers.?
Although many of us were ringing the bell for self-publishing, SFWC did a good job of presenting self-publishing and traditional publishing as equally legitimate paths.?? I think authors, publishers and agents alike are starting to realize how it can be advantageous for even traditionally published authors to dip their fingers into the self-publishing pool, because indie ebooks are incredible platform-builders.
I gave two workshops over four days and participated in two panels.? Below, I'm sharing the two presentations which are uploaded to Slideshare.net.?
The first presentation from Friday morning, titled, How the Ebook Revolution will Transform Writer Careers, examined 10 big publishing industry trends shaping your future as an author.
If you're new to ebooks, here's how to publish and distribute ebooks with Smashwords.
See you next year at SFWC!

"Bless Me, Ultima," the book, is a widely read and critically acclaimed piece of Chicano literature that also has been quite divisive since its publication in 1972. Some critics and parents have decried Rudolfo Anaya's novel as anti-Catholic or too profane and pushed to have it banned from school districts across the country.
"Bless Me, Ultima," the movie, is a mostly gentle and tastefully photographed depiction of a young boy's coming of age in rural 1940s New Mexico. His maturation includes a questioning of the Catholic faith of his parents and a curiosity about the Native American mysticism of his elders. But such musings feel more like an inherent part of the progression into adolescence, a fine-tuning of identity, rather than an intentionally subversive force.
Besides, Luke Ganalon, who plays the boy at the center of the story, couldn't be a more adorably precocious and optimistic little scamp. What sort of damage could he possibly do?
Writer-director Carl Franklin presents the journey of Ganalon's character, the wide-eyed Antonio Marez, in ways that are restrained and sometimes even stiff, despite the magic and violence that co-exist alongside each other. Some of the small-town "types" come off as a bit cartoonish: the eyepatch-wearing villain, the slurring and staggering drunk, But there is an earnestness and genuine sense of affection here that are appealing.
At the film's start, an elderly curandera, or folk healer, has come to live out her final days with Antonio's family in their modest home. Ultima (the formidable Miriam Colon) emerges from a car gingerly but her inner strength is clear, as is her connection with Antonio; as a midwife, she brought him into the world. His former vaquero father (Benito Martinez from "The Shield") and devout mother (Dolores Heredia) are duly respectful of her wisdom and power, while Antonio and his older sisters are a bit awed. (The three elder sons are off fighting in World War II.)
Whispers in town that Ultima is a bruja, or witch, add to her mystery, as does the way she seeks revenge for a curse that's placed on a family member. But her inner kindness becomes more obvious to Antonio as she walks the land with him, teaches him about the usefulness of various plants and offers advice on the importance of spirituality. In case that dialogue alone didn't sufficiently spell out the film's themes, pervasive voiceover from Alfred Molina as the adult Antonio ? beginning with the rhetorical question, "Why is there evil in this world?" ? often hammers us over the head. The inclusion of such prose is a nod to the film's literary origins but probably worked better on the page.
Other moments are more subtle, though, as in the wordless ostracizing Antonio experiences on his first day of school as a poor and illiterate but eager farm kid. One of the first friends he makes is already a young atheist who speaks matter-of-factly about the tragedies that made him doubt his faith at such an early age; he does, however, attend catechism classes each week ? if only to hang out with his buddies.
Amen to that.
"Bless Me, Ultima," an Arenas Entertainment release, is rated PG-13 for some violence and sexual references. Running time: 100 minutes. Two and a half stars out of four.
___
Motion Picture Association of America rating definition for PG-13: Parents strongly cautioned. Some material may be inappropriate for children under 13.

CAMBRIDGE, Mass. Your smartphone snapshots could be instantly converted into professional-looking photographs with just the touch of a button, thanks to a processor chip developed at MIT.
The chip, built by a team at MIT's Microsystems Technology Laboratory, can perform tasks such as creating more realistic or enhanced lighting in a shot without destroying the scene's ambience, in just a fraction of a second. The technology could be integrated with any smartphone, tablet computer or digital camera.
Existing computational photography systems tend to be software applications that are installed onto cameras and smartphones. However, such systems consume substantial power, take a considerable amount of time to run, and require a fair amount of knowledge on the part of the user, says the paper's lead author, Rahul Rithe, a graduate student in MIT's Department of Electrical Engineering and Computer Science.
"We wanted to build a single chip that could perform multiple operations, consume significantly less power compared to doing the same job in software, and do it all in real time," Rithe says. He developed the chip with Anantha Chandrakasan, the Joseph F. and Nancy P. Keithley Professor of Electrical Engineering, fellow graduate student Priyanka Raina, research scientist Nathan Ickes and undergraduate Srikanth Tenneti.
One such task, known as High Dynamic Range (HDR) imaging, is designed to compensate for limitations on the range of brightness that can be recorded by existing digital cameras, to capture pictures that more accurately reflect the way we perceive the same scenes with our own eyes.
To do this, the chip's processor automatically takes three separate "low dynamic range" images with the camera: a normally exposed image, an overexposed image capturing details in the dark areas of the scene, and an underexposed image capturing details in the bright areas. It then merges them to create one image capturing the entire range of brightness in the scene, Rithe says.
Software-based systems typically take several seconds to perform this operation, while the chip can do it in a few hundred milliseconds on a 10-megapixel image. This means it is even fast enough to apply to video, Ickes says. The chip consumes dramatically less power than existing CPUs and GPUs while performing the operation, he adds.
Another task the chip can carry out is to enhance the lighting in a darkened scene more realistically than conventional flash photography. "Typically when taking pictures in a low-light situation, if we don't use flash on the camera we get images that are pretty dark and noisy, and if we do use the flash we get bright images but with harsh lighting, and the ambience created by the natural lighting in the room is lost," Rithe says.
So in this instance the processor takes two images, one with a flash and one without. It then splits both into a base layer, containing just the large-scale features within the shot, and a detailed layer. Finally, it merges the two images, preserving the natural ambience from the base layer of the nonflash shot, while extracting the details from the picture taken with the flash.
To remove unwanted features from the image, such as noise the unexpected variations in color or brightness created by digital cameras the system blurs any undesired pixel with its surrounding neighbors, so that it matches those around it. In conventional filtering, however, this means even those pixels at the edges of objects are also blurred, which results in a less detailed image.
But by using what is called a bilateral filter, the researchers are able to preserve these outlines, Rithe says. That is because bilateral filters will only blur pixels with their neighbors if they have been assigned a similar brightness value. Since any objects within the image are likely to have a very different level of brightness than that of their background, this prevents the system from blurring across any edges, he says.
To perform each of these tasks, the chip's processing unit uses a method of organizing and storing data called a bilateral grid. The image is first divided into smaller blocks. For each block, a histogram is then created. This results in a 3-D representation of the image, with the x and y axes representing the position of the block, and the brightness histogram representing the third dimension.
This makes it easy for the filter to avoid blurring across edges, since pixels with different brightness levels are separated in this third axis in the grid structure, no matter how close together they are in the image itself.
The algorithms implemented on the chip are inspired by the computational photography work of associate professor of computer science and engineering Fredo Durand and Bill Freeman, a professor of computer science and engineering in MIT's Computer Science and Artificial Intelligence Laboratory. With the aid of Taiwanese semiconductor manufacturer TSMC's University Shuttle Program, the researchers have already built a working prototype of the chip using 40-nanometer CMOS technology, and integrated it into a camera and display. They will be presenting their chip at the International Solid-State Circuits Conference in San Francisco in February.

vampire diaries derek jeter Red Bull Stratos Redbull Stratos steve mcnair vice presidential debate Martha Raddatz
A day after the White House press corps expressed "extreme frustration" in not getting access to cover President Obama's golf weekend, which included an outing Sunday with Tiger Woods, the president met with the White House pool aboard Air Force One. The conversation, however, was off the record.
The Washington Post's Scott Wilson, who was serving as pool reporter on Monday evening, thereby writing reports used by the press corps not on board, noted the exchange in a report filed just before 8 p.m.
"AF1 wheels down Andrews at 7:45pm. POTUS came back to have a 10-minute off the record talk with pool at the end of the flight," Wilson wrote.
So did Obama come back to offer an olive branch?
Given that the conversation was off the record, Wilson cannot discuss specifics. But Wilson told The Huffington Post on Monday night that Obama "did not come back with a message in mind."
"He didn't come back because he had to tell us something," Wilson said. "He came back to hang out."
That suggests Obama wasn't there to apologize, but instead to casually talk to reporters on board. Obama doesn't often mix it up with reporters, but he has headed to the back of the cabin on previous occasions to chat with reporters off the record.
Obama hasn't given an on-the-record interview to the Washington Post since 2009, while last sitting down with the New York Times in 2010. So should the White House press corps, which has long complained about access and lack of interviews, allow the White House to set the ground rules?
Wilson explained that if reporters decide not to accept the ground rules, its unlikely Obama will head back there at all. If reporters do, then they'll have the opportunity to get a few minutes with the president, an exchange that may inform their reporting going forward.
However, the president won't be held accountable for any of his words and the lucky pool reporter -- as well as the rest of the press corps -- won't be able to report anything discussed.
Wilson said the situation is "not ideal at all," but noted that "the choice is not seeing him at all or seeing him for 10, 15 minutes off the record." So Wilson, and his colleagues on board, opted for the latter.
"In general, if someone is presented with an opportunity to talk to the president off the record, it's a balancing act," Ed Henry, a Fox News correspondent and president of the White House Correspondents Association, told The Huffington Post. "Some people think that's a really bad idea. Some people think it's a really valuable way to get information about what somebody's thinking -- whether a mayor, Congressman, Senator, or president."
Henry said the WHCA doesn't have a policy "condoning" or "banning" off the record interviews with the president, but allows individual news organizations to decide whether or not to agree to the ground rules.
As for the tension playing out between the White House and press corps this past weekend, Henry said that WHCA's concern is not over a golf game, but about getting at least a "minimal level of access" when following the president around the country and the world. The golf game, Henry said, was "just something that is symbolic of a broader fight."
The golf game was still on the mind of some reporters as the president returned to the White House on Monday night, according to a pool report filed by the Daily News' Joseph Straw.
The president emerged from the helicopter a couple minutes later wearing a white shirt, dark green slacks and a long black coat. He smiled and waved to reporters as he strode toward the South Portico.
As the president walked close by, a group of reporters yelled, in unison, "Did you beat Tiger?!?" He appeared to hear over the helicopter engines, but just smiled and continued on inside.The president's return was open-press.
This post was updated at 10:09 pm after speaking with Ed Henry.

SINGAPORE (Reuters) - Chinese telecommunications company Huawei said on Monday it had not worked with an institute in Singapore on any projects in the specialist field of an American engineer who died mysteriously last year shortly after leaving the institute.
Britain's Financial Times said on Saturday that Shane Todd had been working on "what was apparently a joint project" between Singapore's Institute of Microelectronics, or IME, and Huawei shortly before he died last June.
His parents have said he was murdered because of his involvement in the project, which they say involved exporting sensitive military technology to China.
IME declined immediate comment.
Singapore police said they were still investigating the death of Todd, 31, and would submit their evidence to a coroner. Singaporean pathologists concluded in an autopsy last June that he died by hanging in his Singapore flat.
"IME approached Huawei on one occasion to cooperate with them in the GaN field, but we decided not to accept, and consequently do not have any cooperation with IME related to GaN," Huawei said in a statement.
Todd's area of expertise was Gallium Nitride (GaN), an advanced semiconductor material which has both commercial and military purposes. It is used in things from blue-ray disc players to military radars.
Huawei said that the development of GaN technology was commonplace across the telecommunications industry.
Reuters reviewed evidence the family presented supporting its theory a few weeks after his death, including emails, other documents and photographs.
Interviews with the family, colleagues and friends revealed conflicting views on Todd's state of mind before his death, the nature of his work and how he died.
Colleagues said that he was increasingly depressed in his last few months, but said that his concerns appeared to centre on a sense of failure about his work, and an ambivalence about returning to the United States.
Researchers in unrelated fields have also questioned how, if his work was so sensitive, he was able to take home computer files from his office. His family retrieved a hard drive which included work files in his flat.
IME is part of a network of research institutes managed by government-run Agency for Science, Technology and Research, or A*Star.
A former A*Star researcher now working in the United States pointed out that IME and other A*Star institutes were not military research organizations.
"AFRAID"
At the heart of the family's theory is that Todd was concerned for his safety because of a project with a Chinese company. They believed, through information from his colleagues and from his computer files, that the company was Huawei.
Reuters can't independently corroborate their views about the role of Huawei or the circumstances of Todd's death.
Huawei is one of the world's largest telecommunication equipment companies, but has been blocked from some projects in Australia and deemed a security risk by the U.S. congress on the grounds that its equipment could be used for spying.
Huawei has routinely denied such accusations and has said it is not linked to the Chinese government.
Todd's parents said in interviews in July that Singapore police and IME had failed to properly investigate his death after his body was found hanging from a door in his Singapore apartment on the evening of June 24, two days after he quit IME.
Singapore police say they have handled the case as they have handled other cases, and their procedures follow high international standards. They said in such cases of unnatural death, "no prior assumptions" were made about the cause.
The parents did not immediately respond to emails requesting comment on the Financial Times report but Todd's mother, Mary, said in a telephone interview with Reuters last July that he had been scared.
"I had been talking to him for months for at least an hour every week and he told us he was afraid of being murdered because of his contacts with the Chinese government," she said.
"He quit his job because of it."
Huawei declined to say whether they had been working on other projects with IME. Colleagues said shortly after Todd's death that he had told them at one point he had been working on a project with Huawei but that it was not sensitive or high-level in nature.
One described it as carrying out "measurement test reports" of semiconductors.
The Financial Times said that Todd had been involved in proposing a joint project with Huawei. While it did not say whether the project was approved, it quoted his parents as saying that subsequently he complained to them of being asked to do things with a Chinese company he did not identify that made him uncomfortable.

PayPal will stop allowing personal payments in Singapore on February 20. It said in an email to members that this was due to “regulatory instructions”. People will still be able to make commercial payments for goods and services with their accounts, such as at online merchants, or receive funds, but we can expect that fund transfers between personal accounts will be halted. They’re not clear on exactly what sort of fund transfers will be stopped, but this seems in line with what happened in other countries. According to reports, PayPal Japan’s personal account holders stopped being able to receive or send money to individuals in 2010, and now have to pay a business fee for transactions. The same year, users in Taiwan and Brazil reported that they stopped being able to send personal payments. PayPal’s wording seems to suggest that users will still be able to receive payments from “sales and trading”, so this shouldn’t hurt individuals selling on eBay (which owns PayPal). However, many of the smaller blogshops in the region are run by individuals, and those transfers are to personal accounts. Blogging platform, LiveJournal, has said it has a global pool of over 50,000 blogshops. It said that the transaction volume of Singapore blogshops was $80 million in that year alone. Update: PayPal responded to say that personal payments such as cash gifts or living allowances won’t be allowed. Underlying goods and services will be permitted, and this extends to commercial payments made and received by Singapore users covering personal, “premier” or business accounts. Users can also still receive funds from PayPal users outside of Singapore, and that is dependent on whether personal payments are allowed in the sender’s country. Blogshops, you can rest easy.Source: http://feedproxy.google.com/~r/Techcrunch/~3/AKomXDk51UI/

Infants strut a runway wearing electrodes to show how the walking reflex works

Before you can run, you have to walk, and before you can walk well, you have to walk like a brand-new baby. A new study uncovers the logistics of newborns? herky-jerky, Frankensteinian stepping action and how this early reflex morphs into refined adult locomotion.
In the study, electrodes on infants? chubby legs picked up signals from neurons that tell muscles to fire, revealing that three-day old babies tense up many of their leg muscles all at once. Toddlers, preschoolers and adults, by contrast, showed a progressively more sophisticated, selective pattern of neuron activity.
From birth to adulthood, motor neurons in the spine get an overhaul as neurons in different ?locations along the spine become specialized for various aspects of walking, such as foot position, balance and direction, Yuri Ivanenko of the Santa Lucia Foundation in Rome and colleagues conclude in the Feb. 13 Journal of Neuroscience.
With a helper supporting about 70 percent of the newborn?s weight, a three-day old baby walks across a flat surface while electrodes record motor neuron activity.
