"Laboratory analyses have also revealed indications of organic fibers -- possibly human or animal hair -- inside the stone used to built the pyramids. Davidovits said he believes the materials accidentally fell into the forms when ancient Egyptians were casting the stone."

"An authority on ancient building materials reported evidence Friday that the Egyptian pyramids were built of a remarkable synthetic stone that was cast on the site like concrete. "The new theory challenges the widely accepted belief that the pyramids were built from natural stone obtained from quarries and laboriously moved to the site on wooden rollers. "Dr. Joseph Davidovits said that the synthetic pyramid stone was made with cement far stronger than modern portland cement, which binds together ...

... A.; "A Smoking Gun for an Ancient Methane Discharge," Science, 286:1465, 1999. Monastersky, R.; "Global Burp Gassed Ancient Earth," Science News, 156:260, 1999.) Philosophical observation. Just as natural fires of grasslands and forests eventually lead to vigorous new growth, it appears that methane (a natural product of the decomposition of organic material) also sweeps out old species and replaces them with new ones. No doubt this planetary cleansing is another ramification of the Gaia Hypothesis. Be advised that Gala still lives, and that huge, unstable, methane-hydrate deposits still lie buried under many continental shelves. From Science Frontiers #128, MAR-APR 2000 . 1997 William R.

This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. In addition to the volcanic activity and climate ...

... impossible for cattle to walk across them. However, cattle do not usually try to cross them; they avoid them. The illusory grids work just like the real ones. When cattle approach them, they 'put on the brakes with all four feet,' as one rancher expressed it to me. .. .. . "According to my hypothesis of formative causation..., organisms inherit habits from previous members of their species. This collective memory, I suggest, is inherent in fields, called morphic fields, and is transmitted through both time and space by morphic resonance, a process which takes place on the basis of similarity. From this point of view, cattle confronted for the first time by grids, or by things that look like grids, would tend to ...

Sheldrake has found another possible example of "morphic resonance," as he relates in the New Scientist: "Ranchers throughout the American West have found that they can save money on cattle grids by using fake grids instead, consisting of stripes painted across the road. Real cattle grids, known as cattle guards in the U.S ., are usually made of a series of parallel steel tubes or rails with gaps in between, which make it physically impossible for cattle to walk across them. However, cattle do not usually try to ...

... aquifers were devoid of life. But it was not clear whether these bacteria were native residents of the aquifers or just contaminants from the world above, living solely within the wells. Moreover, no one had established how the bacteria were affecting the environment, if at all." Experiments have now shown that these subterranean bacteria are indigenous and are important to groundwater chem istry. The bacteria feed on organic molecules and display a curious propensity for metabolizing the carbon-13 isotope rather than carbon-12. Thus, carbon dissolved in some deep aquifer water is enriched in carbon-13 compared to surface water. None of the bacteria found so far seems dangerous to humans.

... do know that genes are the blue-prints for the manufacture of proteins. Of these, there may be over 1,000,000 different -- more than ten times the number of genes! These multitudinous proteins are continually being created and transported to where they perform their assigned tasks and are eventually deconstructed. It is this population of proteins (collectively the "proteome") that develops organisms and gives them life. We do not begin to have a blue-print for the proteome, which really tells us how life works. Then, there are epigenetic influences. "Epigenetic?" Yes, the manufacture of proteins according to genome blueprints is altered by chemical groups that attach themselves to strands of DNA. Methyl groups, for example, can completely silence genes. Scientists are ...

Closer study of the announcement reveals that there still remain unreadable snippets of the genome here and there. In fact, the total number of human genes is still in doubt: maybe 30,000, some say 120,000. This wide range of uncertainty does not inspire belief in the accurate readability of this biological blueprint at the present time. Usually left unsaid is the fact that the present blueprint covers only 2-3 % of the territory. That's ...
