Video of blind skateboarder wows the Web

Skateboarding is an extreme sport that takes a tremendous amount of skill, balance, coordination, and fearlessness. Now the world is being introduced to skateboarder Tommy Carroll who has all of that, and then some. Carroll was born with retinal cancer, which left him blind at the age of 2. His lack of sight didn't keep him from his passions, whether it is playing the drums or hitting the halfpipes. He spent hours honing his skateboarding skills and learning to assess his moves by listening to the sounds of his wheels on different surfaces.

A video of Carroll on Vimeo has been viewed more than 500,000 times. It's part of the Dutch retailer Perry Sport's "Be Brave Be Safe" campaign to bring awareness to the importance of wearing protective gear while skateboarding. Says Carroll, "Everybody should know that everything happens for a reason, and that there is always a way to overcome an obstacle if you really want it enough." He plans to take the initiative one step further by setting up a skateboarding club to promote protective gear at Northwestern University, where he is a sophomore.

NEW ORLEANS (AP) ? As 26 children in white polo shirts excitedly walked to center of the Superdome field and prepared to sing, a packed Super Bowl crowd revved up by a day of partying in the Big Easy fell silent.

The chorus from Sandy Hook Elementary School, nearly two months removed from a deadly shooting rampage, joined Jennifer Hudson to deliver a stirring rendition of "America the Beautiful" on Sunday that had some players on the sideline and countless fans in the stands on the verge of tears.

Judging by the responses on social media, the performance appeared destined to become one of the most poignant memories of the Super Bowl, regardless of what played out in the game.

"Sandy hook elementary chorus singing America the beautiful and Alicia keys national anthem makes me proud to be American," model Kate Upton, who was attending the game, said on her Twitter page.

Gerald Rokoff, standing near a portal in the Superdome's upper deck, turned and said, "Beyond beautiful," when the children finished singing.

Numerous viewers made references on social media to tearing up or getting goose bumps.

Sandy Hook is the school in Newtown, Conn., where 20 first-graders and six adults were killed by a gunman on Dec. 14. The chorus was comprised of third- and fourth-graders.

An NFL spokesman said no one with the chorus was available for interviews, but a statement was delivered on behalf of the school.

"We have come to New Orleans to represent the Sandy Hook Family and the community of Newtown, Connecticut," the statement said. "Our wish is to demonstrate to America and the world that, 'We are Sandy Hook and We Choose Love.'"

The children wore green ribbons on their white shirts, which seemed to symbolize the innocence of youth, and stood in two rows of 13 on the NFL's red, white and blue shield logo for the performance. Many smiled excitedly as they sang the first verse. Then Hudson, wearing a black blouse and long, white skirt, fronted them for a second verse that showcased her sterling voice.

Baltimore Ravens coach John Harbaugh watched with his left arm around daughter, Alison, and his right hand over his heart.

A color guard stood with the American flag just in front of the Ravens sideline.

Ravens nose tackle Terrence Cody could be seen on the stadium's video board tilting his head back, appearing to hold back tears.

Fans offered a rousing ovation at the finish, and the chorus then trotted to the 20-yard line and turned, with their hands on their hearts, to watch Alicia Keys sing the national anthem.

Caitlin Hamilton, a 22-year-old English teacher from Dodge City, Kansas, said on Twitter she thought the performance would, without a doubt, be the best part of the Super Bowl.

"It just shows that they're still persevering despite what's happened to them," Hamilton said. "It was a great way to lift up the people of Sandy Hook as well, and to let them know that the people of America support them."

Hamilton said that as a teacher, when she thinks about the shooting she thinks of herself in the same situation. She said Hudson did well leading the song, but the kids were the main event.

"I thought the kids were more inspirational that they could get up there and sing despite everything that had happened to them," she said.

Half Of Canadian Pre-Registrations For BlackBerry Came From iPhone, Android Users

With the debut of BlackBerry's new BB10 OS and its accompanying handsets, many have questioned whether the revamp is enough to pull iPhone and Android enthusiasts into the BlackBerry fold. But a new research note from CIBC analyst Todd Coupland suggests that BlackBerry may be appealing to users on other platforms just as much as it's exciting loyal BlackBerry customers. "In Canada 50% of preregistration at the carriers are not currently Blackberry users,? Coupland said. ?This was a surprise and a datapoint that will be watched closely in other regions."

Milestone of cancer research: Arresting cancers rather than killing them

Feb. 1, 2013 ? The research team of Prof. Dr. Martin R?cken from the Department of Dermatology of the University Medical Center T?bingen has shown for the first time that the immune system is able to drive tumours and tumour cells into a form of permanent dormancy (1). The resulting growth arrest allows tumour control in the absence of cancer cell destruction. This permanent dormancy -- scientifically known as senescence (2, 3) -- may persist for the whole life of the organism. Thus, immunotherapy can prevent tumour development without destroying the cells (1, 4).

Prof. Martin R?cken, Director of the Department of Dermatology of the University Medical Center T?bingen, outlines the current state of tumour therapy as follows: "About 50 years ago the former President of the United States of America Richard Nixon declared the "War on cancer." Strong financial and logistic efforts were undertaken and thought to overcome this devastating disease in relatively short time. At this time, researchers and clinicians learned to use chemotherapeutics or natural killer cells to directly attack the tumour cells and to destroy cancers including their environment. This led to several very important, partly brilliant achievements in the understanding of tumour development and to improved cancer diagnostics. What's more, the treatment of several different cancers was markedly improved by new and innovative operation techniques, radiation, chemo- and immunotherapy. However, the main goal, ie. the decisive victory on cancer, remained absent." "[For some time]," Prof. R?cken explains further, "doubts were raised about the strategy of the "War on cancer" which exclusively focussed on cancer destruction, as for example published in an essay in the journal The Lancet and other recent publications (5, 6, 7)."

Importantly, the work of the R?cken group revealed that immune responses also drive tumours of human origin into senescence. The human body apparently defends itself from cancer by inducing the senescence program in tumour cells thereby inhibiting tumour growth (1).

In this line, two well known signalling molecules of cancer therapy and immunology of infectious diseases move again in the center of attention: the interferons and tumor necrosis factor. Repeatedly, a bulk of researchers and clinicians tried to use these molecules and other techniques to destroy the tumour cells and their supplying blood vessels, and so did the scientists from T?bingen. Surprisingly, however, the R?cken group found that a combination of both signalling molecules, interferon and tumor necrosis factor, stopped the tumour growth in vivo without any signs of tumour or tissue destruction.

In animal experiments, the efficacy of immunotherapy-induced senescence proved to be much better than any other therapy based on "cancer destruction" (4). Most importantly, the common action of both signalling molecules, interferon and tumor necrosis factor, also stopped the growth of human tumours (1).

In the course of a natural immune response, the research team even detected senescence induction in regressing malignant tumours of cancer patients . Seven years ago, it was shown in principle that cancer cells can be shifted towards permanent dormancy or senescence (2, 3). Those theoretical insights were now successfully transferred into a therapeutic approach, here an immunotherapeutic regimen (1, 4).

The new therapeutic option will enable clinicians to approach their goal of a life-prolonging, mainly adverse effect-free cancer therapy. "It is very likely that we can't win the "War on cancer" by exclusive military means.," Prof. R?cken resumes. "Instead, it will be an important milestone to restore the bodies? immune control of malignant tumours."

Wall Street Journal, Washington Post disclose Chinese attacks

Paul Wagenseil , TechNewsDaily ? ? ? 12 hrs.

Following the New York Times' revelation earlier this week of a massive Chinese attack upon its computer systems, a security analyst told TechNewsDaily that disclosing such attacks might become a "badge of honor" among media companies.

The statement by Sean Sullivan of Finnish security firm F-Secure was quickly proved right.

On Thursday afternoon, less than a day after the Times' story was posted online, its ideological rival the Wall Street Journal revealed that it, too, had been attacked by Chinese hackers.

On Friday, the Washington Post, following a scoop by a former staffer, was forced to admit that its networks had been penetrated for years.

The Journal provided fewer details than the Times, but said that "in the most recent incident," hackers had managed to break into computers in the Journal's Beijing bureau in mid-2012.

From there, the Journal said, the intruders were able to access the Journal's worldwide computer network.

"A number of computers were totally controlled by outside hackers," the Journal said.

[Why Most Companies Won't Admit They Were Hacked]

Brian Krebs, who covered computer security at the Washington Post and now publishes his own Krebs on Security blog, was contacted by a former colleague who had been an information-technology staffer at the newspaper's headquarters.

"We spent the better half of 2012 chasing down compromised PCs and servers. [It] all pointed to being hacked by the Chinese," Krebs' source told him.

"They had the ability to get around to different servers and hide their tracks. They seemed to have the ability to do anything they wanted on the network."

The pattern described by Krebs' source fit those described by the Times and the Journal ? an initial break-in to a few machines, followed by an exploration of the entire network and the installation of malware that guaranteed further access.

The Post's own story provided few on-the-record details, other than to confirm the broader outlines of Krebs' story, as Post officials were unwilling to confirm much to their own reporters.

A company spokeswoman denied the assertion by Krebs' source that the newspaper had turned over a server to the National Security Agency for analysis.

The Post's reporters had better luck with an unnamed tech-industry official, who told them, "If every company reported when it was hacked and who it was hacked by, it would be harder [for China] to get away with it."

At least one media outlet seemed to welcome the news of massive Chinese network infiltration.

"The Onion would like to once again affirm our commitment to providing the Chinese government with our employees' passwords and personal information with total and unquestioning cooperation," the satirical newspaper said in a piece posted Thursday.

"The Onion aims to be on the right side of history, and towards that end, China is also welcome to our employees' Social Security numbers, home addresses, and medical and voting histories if ever they would like to see them," it said. "When our Chinese overlords colonize this crumbling land, The Onion will be glad to have been of some modest service."
