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.

Dental Crowns Reveal The Diet Of A Species

15.12.2006 03:54 Science - Source: ScienceDaily Headlines

According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki's Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal's teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature.

The size, number, occlusion and dental crown cusps of carnivores and rodents, such as cats and mice, are very different. Based on their research, the Helsinki scientists discovered that although the teeth of rodents and predators seem very different, the values describing their complexity correspond if the species share a similar diet. Both groups have species that eat both meat and vegetable foods.

The scientists studied the differences in the teeth of various species by measuring the molar crowns of 81 mammalian species and, based on the measurements, creating 3D virtual models of them. The models were then used to develop new methods of measurement, which enable scientists to identify all the parts of teeth that break down the food, the 'tools', as it were.

New database is the first to offer information on phenotypes

The 3D virtual models were entered in the MorphoBrowser database created by the team's scientists. The database now contains data on fossils, existing animals as well as the modified teeth of mutant mice. The open access database for the first time makes phenotypes, or 3D models of the information contained in the genes, publicly available on the Internet. This can be compared to the information on the genetic sequences of different species (such as the human genome), which have been available on public databases for quite a while.

3D measurements enable scientists to determine the diet of extinct animals even in taxonomic groups that have no counterparts in living species. Indeed, the database is particularly useful to evolutionary scientists, who study the diet of extinct species based on the shape of their molars. This new approach also creates opportunities for studying the relationship between dental shapes and developmental biology.

The research was financed by the Systems Biology and Bioinformatics Research Programme of the Academy of Finland.
