New research brings better wireless to remote locations, 80 percent faster GoT downloads

Not getting the bandwidth you need, Heidi? Then maybe the folks at North Carolina State University can help. They've figured out a way to boost multi-hop networks, where data is forwarded across two or more nodes (hops) in order to reach far-flung users. Networks like this can often get bogged down by interference between neighboring nodes. But by using algorithms to automatically modulate the power of each link, the NC State scientists have managed to jump efficiency by up to 80 percent. This has the effect of not only increasing speed, but also saving juice if the systems are battery powered -- like those used by the US Army, which sponsored the research. After all, just because you're away from the throne doesn't mean you have to be out of the game.

Small variations in magnetic fields can be environmental stresses

ScienceDaily (Apr. 23, 2012) ? We are surrounded by a constantly changing magnetic field, be it Earth's or those emanating from devices, such as cell phones. Carlos Martino, an assistant professor at the University of Nevada, Reno, is interested in understanding how these magnetic-field fluctuations change biochemical reactions inside us.

Martino explains that the subject is controversial. "Our research shows that exposure to different types of magnetic fields affect biological response," he says. "More importantly, the exposure levels are well below the standard levels" approved by the World Health Organization. "This raises the concern of safety issues," he adds. Martino presented some of his work at the Experimental Biology 2012 meeting in San Diego, California on April 23.

Magnetic fields come in different types. There are static fields, like those around permanent magnets. Earth's magnetic field is quasi-static, which means it can fluctuate slightly. Then there are radiofrequency magnetic fields, which may change both in intensity and frequency.

Martino's work concerns low-level static magnetic fields, which are one to two orders of magnitude weaker than Earth's field, as well as weak radiofrequency magnetic fields. Martino gives the example of cell phones, which give off very weak magnetic fields. There is debate whether these magnetic fields cause brain tumors in cell-phone users.

Martino says his work on low-level fields and radiofrequency magnetic fields raises "the question of reassessing the standard limit of exposure because we clearly see effects both in vitro and in vivo in the low level and radiofrequency magnetic field range."

But it's not all doom and gloom. In fact, by understanding how weak magnetic fields affect cancer cell processes and tumor growth, Martino sees the potential for a therapy based on weak radiofrequency fields.

He explains his group has recently shown that the reduction of Earth's magnetic field inhibits growth rates of cancerous lung fibrosarcoma cells, colorectal cancer cells and primary endothelial cells. He adds that low-level fields may modulate the production of reactive oxygen molecules, known to affect cellular proliferation and survival. Interestingly, Martino says pancreatic cancer cells show an increase in growth rate in the same low magnetic fields, indicating different cell types react differently to changes in magnetic fields.

Martino has extended his work beyond cell cultures to animal models. For instance, his group has shown that weak radiofrequency magnetic fields inhibit tumor growth in animal models. But in all of his work, Martino says, his group is aiming to get to the bottom of the molecular mechanisms that cause different cells to react in various ways to fluctuations in static and alternating magnetic fields.

Mandel 'thrilled' to work with Stern on 'Got Talent'

Chris Haston / NBC

Howie Mandel believes the upcoming changes to "America's Got Talent," including the addition of shock jock Howard Stern, are thrilling.

By Sean Daly, TODAY.com contributor

Howie Mandel knows exactly where his bread gets buttered.

Sure, ?America?s Got Talent? may turn into ?The Howard Stern Variety Hour? with the addition of the self-proclaimed King of All Media, but that?s OK. The veteran comic and third-year judge insists "without Howard Stern, it would just be season seven.?

NBC and executive producer Simon Cowell have made an all-in bet on Stern, splashing his picture front and center in promos and even relocating the show to New Jersey at his request. Bold moves, indeed, that could bend the fragile egos of some co-stars completely out of shape.

(FYI: TODAY.com is powered by msnbc.com, which is a joint venture between Microsoft and NBC Universal.)

?Honestly, that doesn?t bother me,? Mandel told TODAY.com. ?There is nobody more thrilled to be working with Howard than me. I am such a fan. I think he is one of the brightest people I know. And I think he is an asset to the show. I love the fact that his fans show up to the show. All of a sudden a 12 hour taping is the most exciting place they have ever been. It is like being at a rock concert.?

Q:? Will we see a different type of act this year?? Is the overall talent pool changing?
No, but I think if you look at the show each and every year, each year is more dangerous than the past. The show is more outrageous than it has ever been. Because I think that once you air something ... someone comes on and says ?I am going to jump into 6 inches of water,? then the next guy comes on and says ?I am going to shoot myself out of a cannon? -- which is more dangerous. ?

Q:? And yet every year, the singer always wins.
This year I am hoping (not) and Howard is hoping (not). We always celebrate the variety. This year we have got more groups. And the variety acts are tremendous -- and more dangerous and more spectacular. ?

Q:? Do you think the show is better without Piers Morgan?
I think it is very, very different.? I would never say better.? Everybody has their own taste. I love having Howard. He is truly a friend. Somebody I would socialize with. Somebody I listen to and somebody I am a fan of. I think that the excitement level is going to be ramped up.

Q:? The judges are gelling better?
Absolutely.? I think last year we were three people who came to work. And now we are three gelled. ... This team of judges is a fully formed friendship, and it is really different. I can?t really describe it, but we love every minute of it.

Q:? By the way, congrats on your new show ?White Elephant? getting picked up by NBC!
Thanks. I am very excited. I have been offered many shows since ?Deal or No Deal.? This is the first game show that I have chosen to do. All of the elements that I have loved about ?Deal Or No Deal? are evident in that show. And it is something that we both play. But you are playing it face to face. Instead of playing it in the dark. You are deciding whether you want to pull something away from somebody.

Q:? And once again it kind of involves making a deal.
It does. That is my theme.

Q:? What made you want to host again?
This game so intrigued me. We developed it at my company. I could have hired another host.? But it is just so intriguing. I never thought there would be another ?Deal Or No Deal.? But I believe we have another ?Deal Or No Deal,? and I don?t want to give that up. I am selfish. I want to do it.

No premiere date has been set for "White Elephant," but viewers wanting to see Mandel on the small screen can catch him, Stern and their fellow panelist Sharon Osbourne when the season premiere of "America's Got Talent" airs Monday, May 14 at 8 p.m. ET on NBC.

Do you think Stern will make a thrilling addition to "Got Talent"? Are you looking forward to the other changes in store for the show? Share your thoughts on our Facebook page?

Tips For Flacks From A Former Hack

nick gonzalezThere are two kinds of stories: great ones and the ones that have to be pitched. This article isn?t about great stories. I have a lot of fond memories from TechCrunch -- being there when the YouTube acquisition broke, covering the rise of Y Combinator, and generally speaking to people a recent college grad had no right chatting with, let alone interrogating about their company. However, getting pitched wasn?t one of them. Pitching the press is a lot like trying to close any other business deal -- sans the excitement of any money changing hands. In fact, "selling" a pitch means creating more work for the writer, who has to dig into the details of your pitch and craft a story.
