...oxygen-carriers ranks as one of the most spectacular achievements of molecular biology. Perutz' picture of the "architecture" of hemoglobin, the protein of red blood cells, represents almost 25 years of intensive research and was made possible by his discovery of a new experimental method of X-ray analysis...
...discover the nature of this anatomy has been the central problem of protein chemistry, one that can be solved only by X-ray analysis. Until 1953 such analysis, however, had proved fruitful only when used to determine the atomic arrangement of simple organic compounds at least a hundred times smaller than protein molecules, which contain hundreds of amino acid residues arranged in definite sequences as polypeptide chains...
Perutz discovered in 1953 that by studying the X-ray diffraction pattern from a series of isomorphous heavy atom compounds, each having a heavy atom (such as mercury) attached to a different site on the protein molecule, the problem of discovering the molecular structure of complex proteins could be solved...
...minutes had shut out the Crimson and led it up, 39-39. The Quaker's Dave Robinson, who proved to be Penn's sparkplug for the game, led the early drive with his inside shooting and rugged rebounding. He was aided by the steady outside scoring from forward Ray Carazo...
...long last, U.S. patience has ended. Ambassador Ray Thurston is in Washington for consultation, expects to return to Haiti this week bearing an unpleasant message. The U.S. is cutting Duvalier off the dole, has reduced new aid this year to $2,400,000 (compared with $7,000,000 in 1962), will end all aid as soon as possible. The U.S. will honor its promise of $1,500,000 a year over the next two or three years for a malaria-control program, and will fulfill a $2,800,000 commitment for a jet airport at Port-au-Prince...
