Astronaut Edgar Mitchell Claims Alien Cover-up

Dr. Edgar Mitchell is a veteran of the Apollo 14 mission and he was the sixth man to walk on the Moon. Dr. Mitchell also insists that aliens have visited Earth and that governments are actively covering it up. "I happen to have been privileged enough to be in on the fact that we've been visited on this planet and the UFO phenomena is real," Dr Mitchell said. "It's been well covered up by all our governments for the last 60 years or so, but slowly it's leaked out and some of us have been privileged to have been briefed on some of it. "I've been in military and intelligence circles, who know that beneath the surface of what has been public knowledge, yes - we have been visited. Reading the papers recently, it's been happening quite a bit." Dr Mitchell, who has a Bachelor of Science degree in aeronautical engineering and a Doctor of Science degree in Aeronautics and Astronautics claimed Roswell was real and similar alien visits continue to be investigated. He told the astonished Kerrang! radio host Nick Margerrison: "This is really starting to open up. I think we're headed for real disclosure and some serious organisations are moving in that direction." NASA issued a quick denial. In a statement, a spokesman said: "NASA does not track UFOs. NASA is not involved in any sort of cover up about alien life on this planet or anywhere in the universe. "Dr Mitchell is a great American, but we do not share his opinions on this issue." If Dr. Mitchell is correct about a cover-up than this is exactly the type of denial one would expect NASA to make.

Electrical Properties of Human Skull Finally Determined

Electrical Properties of Human Skull Finally Determined The brain and skull have a lot in common with latex and toothpaste, at least when it comes to electrical conductivity, scientists now find.

The discovery could factor into efforts to diagnose and monitor epilepsy, comas and other disorders as well as researching brain activity.

Knowing how conductive the brain and skull are is key to techniques commonly used to scan brain activity. While research has pinned down the brain's conductivity, exactly how conductive the skull is in a living head has for years remained surprisingly controversial.

Scientists know the brain is more conductive than the skull because the brain does, after all, hold billions of electrically conductive brain cells. Old data used for 30 years estimated the brain was 80 times more conductive than the skull, which is about how much more conductive liquid latex is than crushed cranberries, explained biomedical engineer Bin He at the University of Minnesota. One of the more recent experiments suggest the brain is 25 times more conductive than the skull, which is about how much more conductive latex fluid is than New York City water, He explained.

The electrical conductivity of liquid latex is roughly 1,750 microsiemens per centimeter—hundreds of millions of times less conductive than copper, which is rated at 580 billion microsiemens per centimeter.

To help settle how conductive the skull is, He and his colleagues investigated two children undergoing possible surgery for epilepsy. Beforehand, doctors at times identify the specific brain areas responsible for seizures with electrodes placed deep into the brain. At the same time, in the new study, the doctors measured the brain activity of the children from the outside using electrodes on their scalps.

Computer models built of their heads based off nearly 50 sets of electrical measurements found the brain is only about 18.7 times more conductive than the skull, or about how much more conductive latex fluid is than toothpaste, He told LiveScience. The findings offer "the possibility of much accurate surgical outcomes" in the brain in the future, He added.

The work was detailed earlier this month online by the journal Applied Physics Letters.
