...strings of amino acids manufactured within cells in small granules called ribosomes. But ribosomes are themselves highly complex protein structures that obviously evolved long after protein first appeared. Then how, without the complex ribosome "factories," was primitive protein produced? Last week, in a report published in the journal Origin of Life, a team of molecular biologists suggested an answer. If the hypothesis is correct, says one of the researchers, it could alter Darwin's theory of natural selection and current concepts of genetic engineering...

...consciousness-and how it arose from mere matter. Indeed, he thinks he finally has the answer: consciousness arose from language in two evolutionary steps and appeared for the first time in human history in the second millennium B.C.

If his theory is correct, mankind existed without consciousness for thousands of centuries, functioning dimly in "antlike" colonies nearly up to the age of Confucius and the ancient Greek philosophers. Before consciousness, says Jaynes, mankind was directed by hallucinatory voices, which survive...
...kilometers (124,000 miles) an hour-on a course to intercept Halley's comet in March 1986. Jettisoning the sail, and "flying station" just two kilometers above the comet's head, the ship will take TV pictures and readings to determine the visitor's composition and origin. Says J.P.L.'s Murray: "We don't have a clue about comets. The space sailer could help provide some...
Women act upon their social, political and economic environment according to specific conditions such as class and national origin. Thus, to treat women as a monolithic entity without differentiating the experiences of women as to their specific histories, economic and national conditions, is untenable. Yet this is exactly what many scholars who have bothered to include women in their plan of study have done. They have only used existing records of the thought and lives of women, and have not bothered to research other aspects of womanhood. Therefore, Women's Studies--the study of history, culture and society from...
