...Alamine. A radioactive isotope of carbon has carried three doctors from Boston's Huntington Hospital a little farther toward showing just how cancer cells and normal cells differ. Drs. P. C. Zamecnik, I. D. Frantz Jr., and R. B. Loftfield tagged a protein-building amino acid called l-alzmine with the isotope, watched what cancer tissue and normal liver tissue did with it in test tubes. They found that cancerous livers absorbed the amino acid much faster than normal livers. Eventually, their experiments might help explain why cancer cells grow disastrously faster than normal cells...
...have had a hard time developing resistance to it. One drawback: like streptomycin and other antibiotics, it may cause slight damage to the kidneys. Dr. Brownlee is sure that the kidney damage is caused by an impurity, which can eventually be removed. Meantime, the impurity is counteracted by an amino acid...
Care after operations has improved through blood-typing and blood-banking; new concentrates of amino acids and proteins nourish the patient who cannot eat a normal diet...
Soybeans are nothing new. In thousands of tasty forms, the Chinese have eaten them for thousands of years. U.S. nutritionists have long been pro-soybean, pointing out that soybean protein is as good as the protein of meat, containing all the amino acids which the human body needs. Last year U.S. farmers raised 196,725,000 bushels of soybeans and fed nearly all of them to livestock, which returned only a fraction of the precious protein as meat or eggs or milk...
...Stanley is stalking even bigger game. Viruses are very much like genes, the submicroscopic particles in living cells which control heredity. It is possible, Stanley suggested last week, that slight changes in a gene's amino acids might cause changes in heredity. If so, could man control his own evolution by tinkering with his genes? Says Dr. Stanley: "Perhaps . . . knowledge of this type could affect the destiny of all living things...
