...researchers found in tests on beagles that the anti-biotic tetracycline stops the decay of the bone underneath the gumline that is affected by the disease. Beagles, like most dogs and human beings, contract periodontal disease spontaneously...
...found in Antarctica, where they had been frozen in ice for 200,000 years, Ponnamperuma and his colleagues discovered many amino acids, about half of them different from any that are found in living organisms. Two facts convinced him that the acids are, in his words, "extraterrestrial and pre-biotic": 1) Unlike the Murchison meteorite, which had been contaminated by earthly organic matter after it fell, the Antarctic meteorites were pristine, containing only the amino acids they brought to the earth from space...
...When polarized light was passed through solutions of water and some of the amino acids, it was deflected to the right. "In all the '20 amino acids we know of on earth," says Ponnamperuma, "the polarized light turns to the left." But, he adds, "In all the pre-biotic experiments conducted in our laboratory, we got both lefthanded and righthanded amino acids." His conclusion: the amino acids are not due to terrestrial contamination, but to pre-life forms that evolved somewhere in space...
Kistiakowsky said she predicts advancement in the understanding of genetic engineering, pre-biotic evolution, catalysts, computers, particle physics and the workings of the human brain...
...task of biology teaching... can be fulfilled by an orientation toward the concept of the biotic community... The student must be led to the conception that Germany is his living space to which he is linked by the bond of blood...When this insight is applied to the human biotic community, when the future German racial comrade feels himself to be a link in the German biotic community, and when he is imbued with the idea of the blood relationship of all Germans, then class differences and class hatred cannot take acute forms, as was often the case...
