CES Buzz Kill: FCC Chief Warns of Looming Spectrum Crunch
With all the celebratory buzz at this year's Consumer Electronics Show in Las Vegas, leave it to the government to be a buzz kill.As wireless carriers and manufacturers reveled in their lineup of data-hungry phones, hotspots and tablets, the chairman of the Federal Communications Commission, Julius Genachowski, sounded a stark warning bell about a problem with no quick solutions.
Crunch Time "We need to address the looming spectrum crunch, and we need to ensure the availability of unlicensed spectrum as a platform for American innovation," he said.
Unless Congress acts soon to enable broadcasters to auction their licensed spectrum to wireless carriers, the carriers won't be able to meet demand.
"The incentive auction needs to become law now," Genachowski said. "We're going to get swamped by an ocean of demand."
Expanding spectrum is a priority for carriers, and was a key component of AT&T's failed bid to acquire T-Mobile. The added customer base, which concerned regulators about a monopoly, was small potatoes compared with the acquired spectrum the No. 2 carrier would have gained to support its fast-growing network. In December 2010, the carrier agreed to pay $1.925 billion to chip-maker Qualcomm to buy spectrum licenses in the lower 700-megahertz band.
Its top rival, Verizon Wireless, recently plunked down $3.6 billion to buy spectrum from Time Warner Cable, Comcast and Bright House Networks, and made a separate deal to buy 20 megahertz of Advanced Wireless Services spectrum licenses from Cox Communications.
Genachowski's remarks were similar to those he made at the previous two CES shows since he has been in office. He called the looming crunch ""the dark cloud around the silver lining" that could kill jobs and stifle innovation.
But he said it was important to focus on the right solution.
"Getting it right is as important as getting it done," he said, according to an FCC transcript...

22:52Music has always been social, and Facebook has made several moves to work music into its social media mix. Its latest effort is called "Listen With." Facebook on Thursday rolled out a new feature that essentially opens up a chat room where music lovers can share songs.
"Music is one of the most powerful and fun ways to connect. Whether it's at a concert with a bunch of people or on a long car ride with your best buddy, we love listening to music with our friends," Alexandre Roche, a product designer at Facebook, wrote on the company blog. "But what if you could listen to music with your friends when you're alone, like at work, at home or on the go?"
Let Friends DJ Listen With aims to answer that question with the new music service. As Roche explained it, the feature lets you listen along with any of your friends who are currently listening to music. You can also listen together in a group while one of your friends plays DJ. Facebook has inked deals with several different music services, including Spotify, MGO And Rdio.
"You can listen to the same song, at the exact same time," Roche said, "so when your favorite vocal part comes in you can experience it together, just like when you're jamming out at a performance or dance club."
Here's how it works: Just look for the music note in the chat sidebar. There you can see which of your friends are listening to music. If you want to listen to music with a friend, hover the cursor over their name and click the "Listen With" button. Instantly, the music will play through the service your friend is tapping.
"When a new song plays, you'll come along for the ride, discovering new music while your friend...

A new drug for heat stroke? Implications for malignant hyperthermia
Malignant hyperthermia (MH) is a life-threatening genetic muscle disorder, most commonly triggered in those at risk by certain types of drugs used during anesthesia. Heat stroke, on the other hand, most commonly occurs in individuals in response to physical exertion in hot/humid environments. While their common triggers may differ, the signs associated with MH and heat stroke are remarkably similar – uncontrolled muscle contractions, dangerous increases in body temperature, and muscle breakdown leading to the release of toxins in the blood which may cause cardiac arrhythmias and death. A new medication may be effective in preventing certain forms of heat stroke.

Active compounds against Alzheimer's disease
More than half of all cases of dementia in the elderly can be attributed to Alzheimer's disease. Despite vast research efforts, an effective therapy has not been developed, and treatment consists of dealing with the symptoms. Changes in brain tissues are a hallmark of Alzheimer's. In affected individuals, small protein fragments known as amyloid beta peptides accumulate and are deposited in the gray brain matter. -

22:24Since the discovery of the microscope, scientists have tried to visualize smaller and smaller structures to provide insights into the inner workings of human cells, bacteria and viruses. Now, researchers at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health, have developed a new way to see structures within viruses that were not clearly seen before. Their findings are reported in the Jan. 13 issue of Science.
