'Star Trek Prototype Tractor Beam Developed By Scientists

Researchers at St. Andrews and the Institute of Scientific Instruments, or ISI, in the Czech Republic have figured out a way of generating an optical field that can reverse the radiation pressure of light.

"The practical applications could be very great, very exciting," Cizmar told the BBC. "The tractor beam is very selective in the properties of the particles it acts on, so you could pick up specific particles in a mixture. Eventually, this could be used to separate white blood cells, for example."

"Unfortunately, there is a transfer of energy. On a microscopic scale, that is OK, but on a macro scale, it would cause huge problems," said Cizmar.

"It would result in a massive amount of heating of an object, like a space shuttle. So trapping a spaceship is out of the question."

Tsunami from Asteroid Impacts

One of the people featured in the last episode of "Doomsday Preppers" was afraid that a comet would cause a tsunami and that he would have to be 1500 feet above sea level in order to escape the damage caused by a comet impact. So, I did a little googling, and I found a fabulous and detailed report on the potential danger from tsunami caused by asteroid or comet impact.

In order to save you from a ton of reading, it seems that the worst-case tsunami from asteroid is 230m estimated deepwater wave height (above sea level) tsunami at a point 100km from impact of an asteroid with a 2km diameter. That's about 750 feet above sea level if you are a typical American who can't do rough metric conversions in your head.

Obama to Top Brass: Will you fire on American Citizens?

The Obama administration is openly escalating its campaign against private gun ownership, and shaking up the top ranks of the military command structure --but is it also preparing to make war on the American population? According to a person identified as a former senior military official, the answer to that shocking question is yes.

Officials estimate at least 1 million semiautomatic rifles are owned in the state [of New York], sources said.

And come April 15, 2014 — when Cuomo is expected to be running for re-election — they all have to be registered with the State Police.

But because the rifles have been legal but unregistered until now, authorities don’t know who has them or where they are located.

State officials will be nervously watching the registration figures to see how many gun owners comply, sources said.

“I believe you will have people stepping forward, saying, ‘Here I am. See? I have what you call an assault rifle. Now come and take it away,’ ’’ said a gun-rights activist and boycott organizer.

That’s exactly what state officials are worried about.

“Many of these assault-rifle owners aren’t going to register; we realize that,’’ said a Cuomo-administration source who added that officials expect “widespread violations’’ of the new law. Owners who refuse to register could face a class-A misdemeanor — punishable by up to a year in prison.
