...instructions needed for metamorphosis. The parts become suddenly active; they swell up, forming visible puffs which show that the hormone has told them to do their stuff. Dutifully they release their information by forming "messenger RNA" (ribonucleic acid) that diffuses into the body of the cell and manufactures the protein enzymes that bring about metamorphosis. Then the puffs disappear, and the chromosomes wait for other hormones to come along and tell them to release other items of information...
...Ultracentrifuges to sort out fat-protein combines in the blood by their molecular weights...
...conferees reported on new tests for infectious mononucleosis, the beginning signs of cancer in the mouth, nickel workers' lung cancer, the hyaline membrane disease that killed President Kennedy's infant son two months ago, and a possible mechanism to explain how a violent reaction against a food protein may be the cause of mysterious infant deaths (TIME...
...meat is the staff of life for many nations, for others fish is the very stuff that life is made of. Fishing plays a vital role in the economies of dozens of nations, such as Japan, Ecuador, Peru, Canada and Norway. For many food-short nations, the "panic for protein" to feed their people leads only to the sea, which now contributes a meager 12% of the supply of animal protein consumed by the human race. Throughout the world, the fishing industry not only supports thousands of fishermen-who lead probably the roughest and most ill-paid lives...
...Beerman of West Germany's Max Planck Institute showed pictures of ropy, wormlike chromosomes with strange swellings, and reported on the delicate experiments with which he proved that the swellings are associated with active genes. Geneticists agree that active genes produce RNA (ribonucleic acid) and that RNA produces proteins. Dr. Beerman satisfied himself as to the meaning of the swellings he had photographed through his electron microscope, by finding RNA and protein where theory predicted they should be-right around the lumps on the chromosomes...
