...effect that "the U.S. should fulfill its commitments" with a sentiment more congenial to doves: "We have tried to do maybe too much in the world." Treading gingerly but using backroom muscle on all factions of the party, Humphrey will hold meetings, inviting Democrats of all persuasions to help shape the platform. To counter charges that he was stacking the convention, the Vice President's forces agreed to cede some delegates to McCarthy - provided that their loss involved no danger to Humphrey's nomination...
...than by their academic hardships. As apprentice intellectuals in a country dominated by intellectual tradition, they were deeply dismayed by the content and direction of their stud ies. And by extension of that worry, they are now preoccupied with the place they will take in the world and what shape that world will have. The similarity between their concern and that which has grown up in the U.S. and the rest of Europe reflects a world community of youth that seems certain to play a major part in rebuilding society...
Electric Boy. The greatest effort is made with the Orthogenic School's autistic children. Thwarted or ignored in early childhood by hostile or indifferent parents, victims of autism (from the Greek word for self) sense during infancy that their own actions cannot shape their lives. Consequently, they withdraw into a living-death fantasy existence characterized by fear and stony silence-or, at best, by unintelligible animal noises. Unwilling to admit their own existence because they fear that the outside world will destroy them, many autistics refuse to use the pronoun "I" if and when they do speak...
Each hemoglobin molecule, Perutz found, consists of 10,000 atoms, of which four are iron atoms that have an affinity for oxygen. In the lungs, in the presence of oxygen, the hemoglobin molecule changes shape, moving each of the four iron atoms, which are located in separate "pockets" on its surface, to different positions. This change increases by 300 times the molecule's attraction for oxygen atoms, pulling four of them into combination with the iron atoms. It is only because there are 280 million hemoglobin molecules in each red corpuscle that the blood has sufficient oxygen-carrying capacity...
...molecule delivers its oxygen to the body's tissues, it reverts to its original shape and attracts charged hydrogen atoms. The blood thus becomes alkaline, forms a temporary chemical bond with carbon dioxide and water from the tissues in the form of bicarbonate and carries it to the lungs, where it changes back into water and carbon dioxide before being exhaled. The change of molecular shape is important, says Perutz, "because it is the most elementary manifestation of the property of a living system that can turn chemical energy into movement...
