...given organ for its growth and normal function. Perhaps it may then become feasible to supply the living body with the substances indispensable to the development of any organ, or to its regeneration. Instead of injecting hormones into a patient, we .would supply the glands with appropriate nutrient substances and induce them to develop, or to regenerate, and again to secrete hormones. To bring about the regeneration within the pancreas . . . would be a far more efficient method of treating diabetes than to inject insulin daily into the body of the patient...

...tongue darting in & out of the wound four times a second. When Dr. Ditmars brought back four vampires from Trinidad, it seemed a good chance for scientists to check another theory-that the bat's saliva contains some substance which prevents blood from coagulating and so keeps the nutrient liquid flowing freely...

...tomato plants-pressures high enough to serve tomato plants hundreds of feet tall. The trouble with previous pressure experiments, it appeared, was that they were made on dead or dying roots. At Princeton, Dr. White has an apparatus which keeps detached roots alive indefinitely by supplying them with nutrient fluid. When he attached glass tubes carrying columns of mercury to his tomato roots, the mercury went up until it indicated a pressure of more than eight atmospheres (125 Ib. per sq. in.), at which point the powerful roots broke his apparatus...

...shallow tanks of nutrient solution, Dr. Gericke has grown tomatoes, potatoes, corn, beans, gladioli, begonias, dozens of other plants and vegetables-free from drought, disease, insects, floods, erosion (TIME, March 1). In a tank of 1,100 of an acre area he grew 1,226 Ib. of lush red tomatoes. His giant tobacco plants are especially impressive (see cut). From 25 sq. ft. of water he got 100 cantaloupes, declared this to be 20 times the yield expected from soil. Pushing against the roof of his greenhouse, with its massive roots in water, is an 18-ft. banana plant...

...objects to the fact that a dozen or more small chemical companies have sprouted up to sell nutrient salts to amateurs or professionals experimenting with hydroponics. These have names like Chemi-Grow, Chemi-Crop Co., Shur-Gro Fertilizer Corp. They are legally within their rights, since hydroponics cannot be patented. The only patent which Dr. Gericke holds is for a container to diffuse the chemicals through the solution. But he argues, against the companies, that no formula works well for all plants, all climates, all conditions: and that even if they made a great variety of formulae there are other...
