Crowds and Crime. Biologist Paul Ehrlich, Stanford University's outspoken population expert, has always predicted war, pestilence and famine as eventual consequences of mankind's proliferation. Citing several studies, he said at the A.A.A.S. meeting that population pressures already are spawning new social problems. In particular, crowded cities seem inevitably to increase agressiveness, which manifests itself even now in general disorder and steadily soaring crime rates...
...Yale biologist announces he has synthesized a substance that, if placed in the world's water supply, will create peace on earth forever, as well as quadruple the productivity of all soil, clear the nasal passages and the Suez Canai, and act as a non-polluting automobile fuel...
Deadly Message. Gallo's hypothesis tends to support the iconoclastic ideas of Howard Temin, a University of Wisconsin molecular biologist who long espoused what his colleagues considered a major heresy. According to accepted theory, the hereditary information in the chromosomes of all cells passes in the same direction. Double-stranded DNA molecules make single-stranded messenger RNA molecules, which then direct the production of proteins, the basic building blocks of every cell. Temin contended that the process is sometimes reversed: RNA, he insisted, could make DNA. Otherwise, he asked, how could cancer-causing viruses−which consist of bundles...
...orbits of Mars and Jupiter. But previous claims have invariably been discredited because the amino acids were suspected to be of terrestrial origin; they could easily have contaminated the meteorites during or after their plunge through the earth's atmosphere. Even Ponnamperuma, a highly respected exobiologist (extraterrestrial biologist) at NASA's Ames Research Center in California, admits that only a thumbprint on a beaker could introduce amino acids into a meteorite sample. But his conclusion about the Murchison meteorite is strongly buttressed by other impressive evidence...
...molecular biologist's contribution to medical research is already large, and is likely to grow with the expansion of cancer research. An examination of Molecular Biology of the Gene will give the reader not only a good understanding of molecular genetics, but a solid foundation for keeping up with future advances in medical and biological research...
