Michael Bisping doesn?t want to hear about Jason Miller?s stamina, ?Mayhem? just needs work on his game
Michael Bisping just wanted a little more credit following his win over Jason "Mayhem" Miller, so he scolded the media who were saying the American ran out of steam early in the fight.
"Did you see the pace of the fight? Did you see how many punches I was throwing? Any time I stop someone it's because they gassed. I guarantee Jason didn't gas. I guarantee Jason could've gone five rounds," said Bisping.
The Brit said he was the reason Miller was physically and mentally sapped by the middle of the third round.
"Guess what? You might have cardio but when someone's landing big body shots like I was ... kneeing you in the stomach and punching you repeatedly in the face, your cardio gets affected," Bisping said. "Even the best runner would gas. You get Lindford Christie in there and beat the [expletive] out of him, see how fast he runs the 100 meters."
Bisping believes Miller can compete in the UFC, but the 30-year-old MMA veteran needs a lot of work.
"I've got good takedown defense and he took me down. Against someone less experienced, he could've gotten a submission. He gave me a tough first round," Bisping said. "If I were him, I'd go train striking, keep his shape a little bit more when he's standing up and be a little more orthodox."
Because Miller was launching his head each time he threw an overhand right, it almost became a short night for Bisping. He got drilled in the first when the fighter's clashed heads.
"He was throwing it and really committing with his head. I could feel it instantly and a big lump on my head," Bisping said. "When I'm sparring I prefer a really good, high-level boxer. Someone who's really good and technical. I do great against those guys. Someone who's unorthodox, a beginner if you will ... they catch you with shots because they do stupid things that they're not supposed to do. They don't follow the guidelines."
Miller has survived solely on his grappling by fighting in Japan, Strikeforce and some of the minor leagues around the U.S. He definitely needs to dedicate himself to the stand-up game or his stay in the UFC could be very brief.

White House urges Cuba to release U.S. contractor (Reuters)
WASHINGTON (Reuters) ? The White House on Friday urged Cuba to immediately release jailed U.S. contractor Alan Gross and accused Havana of trying to use him as a "pawn."
"It is past time for Mr. Gross to return home to his family where he belongs," White House spokesman Jay Carney told reporters in response to a question. Carney said Gross's detention was "unjustified."
Gross was sentenced in Cuba this year to 15 years in prison for crimes against the Cuban state. Saturday marks the two-year anniversary of his arrest.
Gross had been working for a U.S. Agency for International Development (USAID) pro-democracy program and Havana accused him of illegally distributing Internet and satellite communications equipment on the island.
"Cuban authorities have failed in their effort to use Mr. Gross as a pawn for their own ends," Carney said. "They must heed the call of Mr. Gross's family and friends, the international community and the United States, to immediately release Mr. Gross."
President Barack Obama's administration, which has eased restrictions on U.S. travel and remittances to the communist island, has said Gross must be released before any further moves to improve U.S.-Cuba ties can go ahead.
Michael Kinnamon, the head of the U.S. Council of Churches, visited Gross in a Cuban jail this week and met with Cuban President Raul Castro.
"The president also expressed his concern over the health of Mr. Gross's family but we did not discuss his release," Kinnamon said on Friday.

Justin Bieber Tweets Encouragement To 'X Factor' Contestant
'Keep your head up,' Bieber wrote to eliminated teen Drew Ryniewicz.

There was just no consoling weepy 15-year-old "X Factor" contestant Drew Ryniewicz on Thursday night when she was sent home in an double elimination episode. The quirky teen with the fluttery, dramatic voice was in tears for most of the episode and when her time came even usually unflappable mentor Simon Cowell seemed choked up with emotion.
But avowed Belieber Ryniewicz got some serious consolation less than an hour after her run on the show ended when none other than idol add link: Justin Bieber Tweeted out a message of support to the Chino Valley, Arizona high schooler.
"@drewryniewicz keep your head up," Bieber wrote to the fan who showed off her bedroom shrine to the Canadian pop star during her audition episode. "I lost my first competition too. This is just the beginning for u. Never say never. Best wishes." Though the departure from the show hurt — fellow teen rapper Astro was also sent packing — Ryniewicz tried to keep an upbeat attitude, following up Bieber's Tweet with her own message of hope. "Hey thank you for your love!," . "I'll miss the xfactor but have a lot more in stor for you all! Upbeat? Yes."
Because she's a teenage girl who auditioned for the show with an impassioned take on Bieber's "Baby," Drew couldn't help bragging a short time later, "Justin Bieber follows me now!" Good sport that she is, Drew also gave props to the remaining girls on Team Simon, Melanie Amaro and Rachel Crow, while accepting some positive vibes from Astro, remaining contestant Marcus Canty and former "American Idol" contestant Casey Abrams.
One of Cowell's favorites, Ryniewicz was done in by her piano-driven, seated take on Michael Jackson's "Billie Jean," which the show's other judges dinged for being too sleepy. While Cowell said that criticism was "absolute nonsense," fiercely defending his decision to have her sing another ballad — though Drew seemed to have wanted otherwise — on Thursday night he made a startling admission. "The reason Drew is in this position tonight is my fault," said Cowell, typically adverse to any second-guessing or display of weakness. "I take total responsibility. I genuinely believe you deserve a second chance. I'm begging these two [judges] to give her another chance."
But, alas, Cowell's fellow judges cast their votes against Drew and Cowell seemed ready to storm off the set, getting up from his chair with an angry look and taking the stage to console his charge while staring daggers at his fellow panelists and angrily ignoring host Steve Jones' requests for comment.

Scientists and engineers have proven the worth of quantum cryptography in telecommunication networks by demonstrating its long-term effectiveness in a real-time network.
Their international network, created in collaboration with ID Quantique and installed in the Geneva metropolitan area and crossing over to the site of CERN in France, ran for more than one-and-a-half years from the end of March 2009 to the beginning of January 2011.
Published today, 2 December, in the Institute of Physics and German Physical Society's New Journal of Physics, the researchers' study documents the longest ever deployment of a quantum key distribution (QKD) network and demonstrates its robustness and reliability when coupled with a real-time telecommunications network.
Cryptographythe practice of protecting information from third partieshas long been achieved by encrypting data with a set of complex mathematical algorithms; however, with the power of computers continuing to increase, it is becoming harder to make these algorithms watertight.
Physics has rather conveniently come up with a solution to this ever-growing problem through a process known as quantum key distribution (QKD). QKD is a process that enables two parties to share a secret key before using that key to protect data they want to send over a network.
The key that the two parties share is built up from a stream of photonsthe basic unit of light. In a theoretical scenario where Alice and Bob want to protect a piece of information with a quantum key, Alice would send a stream of photons to Bob with each one having a specific orientation, called polarisation: photons can 'spin' vertically, horizontally and diagonally.
Bob would then attempt to measure the photons coming in by randomly choosing which direction to measure them in. Sometimes he will choose the correct orientation, other times he won't. Alice and Bob would then share the measurements using classical communication methods, simply stating if Bob was right or wrong, but not mentioning the actual direction the photons were spinning in.
Alice can then discard all of Bob's wrong measurements and use the correct ones to encrypt their secret data. The beauty of QKD is that if a potential eavesdropper wanted to get hold of this key, they would actually destroy the photons when trying to measure them. As a result, they would need to send their own stream of photons on to Bob to cover their tracks, but this would introduce errors and be discarded during key distillation.
QKD is not a new phenomenon and has already been used for a number of applications: notably by ID Quantique to protect the votes in Geneva's elections and in other commercial installations where high security is needed.
For QKD to become more widespread in the commercial world, its reliability needed to be thoroughly tested as these networks run constantly all year round. Furthermore, the robustness of the network needed to be demonstrated as the systems are being taken out of safeguarded laboratories and placed into more demanding environments.
Co-author of the study Dr Damien Stucki said: "This experiment is a big step in the direction of a wider deployment of QKD in telecommunications networks. From a scientific point of view, the deployment of the quantum layer over a duration of 21 months with high reliability is very significant.
"The SwissQuantum network was very reliable, with the only interruptions coming from external problems, such as power cuts and air conditioning problems, not the QKD layer."
