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.

No Sunglasses Required For Fish Supper

Science Daily — Fishermen are always looking for a tasty catch - but it is the fish that have a natural advantage when it comes to spotting dinner, according to new research from The University of Manchester.

In a paper published on 17 October 2007 in the Biophysical Journal, Dr Nicholas Roberts from The University's Photon Science Institute and the School of Physics and Astronomy reports how individual light sensitive cells within the retina of goldfish are able to detect polarised light.

It's believed this type of polarisation vision improves visual contrast and can help an animal catch its prey more easily.

Researchers say this latest research is important because it is the first direct experimental evidence of a polarisation detection mechanism in any normal vertebrate eye.

They believe that discovering how single cells work as polarisation detectors may lead to new developments in man-made microscopic detection or information display technologies.

Dr Roberts says: "Vision is the primary sense of many animals and the way they see their world is of fundamental importance to understanding aspects of their behaviour.

"Numerous animals have amazing visual abilities, which allow them to see the world in very different ways. One such ability is polarisation vision.

"Just as fishermen wear Polaroid sunglasses to help improve contrast, many different animals - including fish - have evolved to do the very same thing without the need of sunglasses. It is a surprisingly common ability throughout the animal kingdom."

For the study Dr Roberts used 'laser tweezers' to manipulate the cells in three dimensions. This meant that for the first time, the absorption of single photoreceptors could be studied in the same orientation they are in the retina.

The research team stress they have so far only investigated one of the three colour channels known to play a role in polarisation vision.

Dr Roberts adds: "This is just the first step in understanding the full mechanism that allows vertebrates to see polarised light, but we see these initial results as extremely encouraging.

"We are now examining in much greater detail the underlying biochemical properties that make only some photoreceptor cells polarisation detectors.

"The real challenge is building an integrated picture of vertebrate vision. We are aiming to discover how both the biochemical and biophysical aspects of visual cell function link to the way polarisation information is first analysed, processed and then relayed to the brain."
