...oxygen in it, but was made of gases like methane, hydrogen and ammonia. Scientists have also proved that when this gaseous mixture is put in a flask with a little water in the bottom, and an electric discharge is passed through it, the chemical reaction produces an accumulation of amino acids in the water. Since amino acids are the building blocks out of which proteins are made, and proteins are the chemical framework of all life on earth, the first chemical step toward life could have come about naturally on the primitive earth, pushed by lightning flashes or perhaps cosmic...

...striking drop in TB mortality in the last few years (to about 12,000 in 1959) has been brought about by treatment with one or more of three wonder drugs: streptomycin (1944), para-amino-salicylic acid or PAS (1944) and isoniazid (1951). Eradication of the disease depends on full use of drugs, following aggressive case finding. There are now 400,000 known TB victims in the U.S. (150,000 with active disease), and an estimated additional 400,000 who have escaped detection...

...Florida State University reported progress toward creating life in the laboratory. Experimenters have long known that when a mixture of methane, ammonia, carbon dioxide and water vapor (all probable constituents of the earth's primitive atmosphere) is bombarded with electric sparks or high-energy radiation, amino acids are produced. Amino acids are the building blocks that form the multitudinous proteins in living organisms, and Dr. Fox carried the process a step farther. When he heated a mixture of amino acids with polyphosphoric acid as a catalyst, he got big molecules with many of the properties of proteins, i.e., they...
