“This would open up observations of the gravitational-wave analog of the Cosmic Microwave Background from the extremely early Big Bang, and also communications directly through the interior of the Earth.”

It appears that according to Robert Scoble’s blog, CMU came in first, finishing a full half hour ahead of the next best team which ended up being the Stanford team.

Hope you enjoyed the videos….
I wonder when this will become a reality for the everyday commute to work. I think these will first see widespread use as a military vehicle used for refueling or cargo transport in dangerous arenas.

Washington (AFP) Jan 22, 2007 - China has acknowledged conducting an anti-satellite missile test earlier this month, but said it was not a
threat to other countries or a sign Beijing is militarizing space, the
State Department said Monday. Assistant Secretary of State Christopher
Hill raised US objections to the test with senior Chinese officials
during a visit to Beijing over the weekend, State Department spokesman
Sean McCormack said.

First off, check out this excellent series of articles on cholesterol by one of the world’s foremost researchers on the subject: Uffe Ravnskov, MD, PhD.
The doctor writes about the cholesterol myth. There’s so much to learn about this subject, you owe it to yourself to read up: http://www.ravnskov.nu/myth1.htm
All that can be said for sure about cholesterol is that if you exercise, your body increases production of the ‘good’ cholesterol or HDL, and decreases the ‘bad’ cholesterol, or LDL.
It is strange to note that in some study groups, those with the largest amounts of the ‘good’ cholesterol ended up either having an equal number of heart attacks, or more heart attacks than the groups who had a greater amount of the so-called bad cholesterol.
If that isn’t bad enough, a lot of studies are now saying that trans-fats and chemical additives in foods are a lot worse for you than cholesterol or natural fatty acids. check out this article on how trans-fats are far worse than butter or beef or bacon or natural oils. It supports New York City’s attempts to ban trans fats from the city.
Trust me, take my advice and stay away from Mcdonalds, or any of that sort, if you can, eat a lot of vegetables, beans, and natural or ‘organic’ foods. And please eat some meat every once in a while, every vegetarian I know is chronically ill for some reason or other, which usually stems from their lack of meat intake.

I know it sounds crazy, but it is actually true. And of course, Chinese scientists have done it:
“In the past, researchers at Northwestern Polytechnical University in Xi’an, China, used ultrasound fields to successfully levitate globs of the heaviest solid and liquid—iridium and mercury, respectively. The aim of their work is to learn how to manufacture everything from pharmaceuticals to alloys without the aid of containers. At times compounds are too corrosive for containers to hold, or they react with containers in other undesirable ways.
“An interesting question is, ‘What will happen if a living animal is put into the acoustic field?‘ Will it also be stably levitated?” researcher Wenjun Xie, a materials physicist at Northwestern Polytechnical University, told LiveScience.
Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.
After the investigators got the ultrasound field going, they used tweezers to carefully place animals between the emitter and reflector. The scientists found they could float ants, beetles, spiders, ladybugs, bees, tadpoles and fish up to a little more than a third of an inch long in midair. When they levitated the fish and tadpole, the researchers added water to the ultrasound field every minute via syringe.
The levitated ant tried crawling in the air and struggled to escape by rapidly flexing its legs, although it generally failed because its feet find little purchase in the air. The ladybug tried flying away but also failed when the field was too strong to break away from.” read more here
The thing to remember is that the amount of energy required to levitate a human being also would rip a human being apart. The key is to create some kind of impervious vessel….. hmmm…
