Cloning a Mammoth?

A recent report states that scientist might be able to clone a mammoth after finding well-preserved bone marrow in Siberia. Russian and Japanese scientist are stating that they will launch a joint research project next year with the scope of cloning the gigantic mammal.

This was all possible because with the increase in temperature because of global warming, there have been parts of Russia that have thawed which lead to the discoveries of a few mammoth skeletons.

The cloning will be possible by replacing the nuclei of an elephants egg cell with the ones that were taken from the mammoths marrow. As with almost all cloning, after that is done the embryo will be placed in the womb of an elephant, since the mammoth and elephant are close relatives.

Now, my question is if this would be an ethical thing to do. While it's not cloning humans, cloning in general is a very controversial subject. I'm all for it, but some people still resent the day Molly the sheep was successfully cloned. And even if the scientist will be able to find enough intact DNA, a lot of things can still go wrong in the process, so the chances of reviving a species that has been gone 10,000 years are still very, very slim.

Light created from nothing!

The dynamic Casimir effect has finally been proven true after more than 40 years since it was predicted. A team of scientist in Sweden lead by Chris Wilson are the ones that made it possible. Wilson said that "they were very happy when it worked" and I'm not surprised.

How'd they do it? Well first, they got a SQUID, or Superconducting Quantum Interface Device, and made it move at the speed of light in a vacuum. The rapid movement of the SQUID starts transferring its kinetic energy to virtual particles. What did this yield? Photons, also know as light started appearing, therefore proving that space is not empty, even though it is a vacuum.

That being said, I don't think we're gonna have any light sources made out of virtual photons any time soon, because Wilson and the team aren't yet sure as to how many "real" photons they can get get out of the "virtual" ones.

NASA's Curiosity to launch on November 26

NASA's new rover called Curiosity will launch from the Cape Canaveral Air Force station located in Florida.
Curiosity's destination and mission objective? It's supposed to land inside the Gale crater on planet Mars. There, it will look for signs on whether Mars' environment was ever suitable for microbial life.

Source: NASA
Much longer and also much heavier than its two predecessors, Spirit and Opportunity, Curiosity weighs in at 900kg and is 3 feet long. It boasts ten scientific tools that all together weigh 15 times more than Spirit or Opportunity's scientific tools.
Curiosity is supposed to get to Mars in August of next year, after a long and treacherous 8 month journey through our solar system.

Alert - Scientists Say NIBIRU Is Responsible For The Mass Extinctions !






This segment from the cable TV show: "Universe: Unexplained Mysteries features UC Berkeley's Dr. Richard Muller who has for decades predicted a "Dark Star" binary twin to our Sun, which he calls "Nemesis," whose elliptical orbit he believes it is responsible for the strong cycle of mass extinctions which occur every 26 million years on Earth.
