The inquiring intelligence of the editor of the New Republic is turned on the ingenuities, the surprises and miracles of modern science. The result is a popular, vely, untechnical coverage of laboratory accomplishments. Genius and genes, enzymes and benzene rings, vitamins and hormones,rays and atoms and stars -- all providing benefits for today, promises for tomorrow. The germicidal lamps which may obviate the common cold, sprays to keep apples on the bough until picked, magnets to hold false teeth in place -- from the sublime to the practical. Fascinating material, speculative, tangible, hopeful.
