Flattr Finally Lands Big Dailymotion Deal, But Its Business Model Still Sucks
Flattr, a social micro-payments platform which we've likened to a "Like button with cash" is to partner with the second biggest video site on the Web, Dailymotion. The distribution deal is targeted at Dailymotion's key content creators in its Motionmakers category. A cynic might call this a mere test of the platform to see if it can be rolled out across the site more widely. But both parties insist this is a card-carrying 'deal'. Suffice it to say Flattr has been crying out for a big distribution partner and yearned after one for the last two years. But TechCrunch remains skeptical that even this deal will lift the startup out of the early adopter crowd into the mainstream as there remain significant issues with its business model. Then again, at least they now get a real stress test.benetton ads cornucopia best buy black friday deals thanksgiving crafts matt cassel snowman playstation network down

Vitamin D supplements may protect against viral infections during the winter

New research published in the Journal of Leukocyte Biology suggests that the older population could benefit from vitamin D supplementation in autumn and winter to protect against viral infections
Vitamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases. Since vitamin D levels decrease during autumn and winter when days are shorter and sunlight is relatively weak, this may explain why people are more prone to viral infection during these times. It also suggests that vitamin D supplementation, especially in older populations, could strengthen people's innate immunity against viral infections.
"There are numerous studies showing the benefits of maintaining adequate Vitamin D levels. As more and more research into Vitamin D is conducted, we are learning that it is extremely important for human health. Our study is no different, and vitamin D supplements should be considered one of many tools that might help when conventional therapies are not enough," said Victor Manuel Martinez-Taboada, M.D., a researcher involved in the work from the Division of Rheumatology at the Hospital Universitario "Marque's de Valdecilla," Facultad de Medicina at the Unversidad de Cantabria, in Santander, Spain.
To make this discovery, the researchers compared the changes in the blood levels of vitamin D among three groups of healthy subjects: young (age range: 20-30), middle (age range: 31-59), and elderly (age range: 60-86). They found decreased levels of vitamin D with aging, prompting researchers to compare whether such changes kept any relationship with toll-like receptor (TLR) expression measured on lymphocytes and monocytes and function after in vitro stimulation with specific ligands for each of the nine human TLRs and measurement of effector molecules, such as proinflammatory cytokines. Specifically, they found that the TRL most affected by a vitamin D insufficiency is TLR7, which regulates the immune response against viruses. Finally, scientists studied whether there was any difference in the three age groups depending on the season of the year since it is well known that a limited sun exposure during darker winter months is related with vitamin D deficiency.
"Any school teacher will tell you that people tend to be sicker during the winter than any other time of the year," said John Wherry, Ph.D., Deputy Editor of the Journal of Leukocyte Biology. "There have been numerous studies showing several environmental factors during winter months may allow viruses to spread easier. This study shows that sunlight, or more precisely the lack of vitamin D, could have a role in the seasonally higher rates of infection. More extensive studies must be conducted for this link to be conclusive, but since vitamin D supplements are inexpensive and generally safe, this is a really exciting discovery."

The Voice Recap: Semifinal Surprises?
The remaining eight contestants on The Voice – two from each coach's team – gave what could be their final performances during Monday's semifinals.
With the season finale set for next Tuesday night, audience votes plus scores from their respective coaches will determine which four singers advance.
Blake Shelton, Christina Aguilera, Adam Levine and Cee Lo Green will have a chance to weight their hopefuls' chances tonight. Who will they favor?
From Team Blake, Erin Willett became overwhelmed with emotion after a powerful performance of David Guetta's current radio hit, "Without You."
"I just emotionally kind of got lost," a tearful Willet, who lost her father during the competition, revealed to MC Carson Daly after her performance.
"I would give anything to have a tenth of the talent that you have," said Shelton, in what may be his highest praise. "Your singing is unbelievable."
Erin Willett - "Without You" (The Voice)
Shelton, whose own father passed away in January, added: "But more than that, Erin, I'd give anything to have the strength that you have."
"I know what that song means to you," the country star added. "It means the same thing to me right now also. And you held it together."
Still, it was Blake's other semifinalist, Jermaine Paul, whom Shelton described as the "frontrunner" after a heartfelt take on Journey's "Open Arms."
"Jermaine is the guy," Shelton told his protégé. "Every time you get on stage, you separate yourself a little bit more from the rest of the pack."
Adam Levine begged to differ.He told Team Cee Lo's Juliet Simms, who closed out the night with James Brown's "It's a Man's Man's Man's World," simply "You're the one to beat."
Aguilera, on the other hand, had high praise for Team Adam's Katrina Parker. "I just encourage Adam to really look at you," she told Parker.
Her version of The Fugees' "Killing Me Softly" will guarantee that.
"I know that probably the obvious, predictable choice for Adam would be to be swayed towards [his other finalist, Tony Lucca]," she said.
"But I'm telling you, take a look at Katrina Parker because she's a star."
Aguilera, who donned a tiara for the evening for some reason, really does not favor her one-time fellow Mousketeer Lucca for some reason.
also enthusiastic about her own protégés, Chris Mann and Lindsay Pavao.
America's votes and the coaches' points will be awarded tonight, narrowing The Voice field to four. Who do you think will make the finals?

LG launches LG Cloud, blows raspberries at S-Cloud
Four days before the purported launch of Samsung's cloud service, Korea's other technology giant has unveiled LG Cloud. The eponymous service offers 5GB free space as standard, while owners of LG's Smart TVs or smartphones will get 50GB free for six months. It'll push content between your devices, appropriately compressed for the medium, so high definition images on your TV will be slimmed down to save your phone's data cap. The free beta begins in South Korea and the US from May 1st, with a global rollout pencilled in for next year -- but don't worry, the company made it clear you'll be able to use it on your holidays, if you can find a signal.
