...flames, men are set on fire in their castles, tiny firing squads claim victim after victim, a man is broken on a wheel, 21 corpses hang from a single tree. Callot's etchings are too small to roar with rage, but all the brutality is there, etched in acid fury...
...Portugal. He confronted growing unrest at home, bloody rebellion in his big African colony of Angola, found few sympathetic world allies anywhere except in South Africa. But in his first interview in five years (to Brazil's 0 Cruzeiro Correspondent Mario de Moraes) the old autocrat was as acid and abrasive as ever...
...Huppert began with the generally accepted fact that a normal cell contains chemically coded information-in ribonucleic acid (RNA) or deoxyribonucleic acid (DNA)-which determines how it reproduces itself. But, he suggested, ''a cell may acquire some wrong genetic information,' perhaps through the entry of a virus into the cell. The virus need not necessarily multiply within the cell; all that is necessary is for a piece of the virus' RNA or DNA to be substituted for part of the cell's normal nucleic acid...
...cases, said Dr. Huppert. it will incorporate the "foreign" information and reproduce abnormally, starting a cancer. The likelihood of this is increased when an other, non-cancer-causing virus happens to be present. Dr. Huppert said he and his colleagues have induced tumors in animals with the nucleic-acid "core'' of a virus found in a human tumor...
...essence of heredity-the delicately complex deoxyribonucleic acid known as DNA-has been extracted virtually intact from human sperm for the first time by Doctors Ellen Borenfreund and Aaron Bendich. The "almost impossible" feat promises to shed new light on the transmission of hereditary traits in mammals and on the origin of genetic abnormalities. After experiments with the sperm of fish and fowl, rabbits and bulls, the Manhattan researchers carefully washed the human sperm to rid it of enzymes, then treated the DNA tough protein topcoat with a chemical that freed the 400,000 chainlike DNA molecules for examination...
