...weeks since successful experiments in acceleration of plant growth by artificial light were announced (TIME, Nov. 5). Now we have the next step: etherizing them to make them grow. Prof. David Lumsden, of the Federal Horticultural Board, found out that if a "shot of dope" is given to a plant either by inhalation or a hypodermic needle, exactly the,contrary of the effect of ether on human beings is produced. Instead of putting plants to sleep it can produce overnight perceptible fresh green shoots from rose bushes dug out of frozen ground in midwinter. Kept indoors on the ether diet...
Further work with electrification of plants, by Prof. R. B. Harvey, of the University of Minnesota, has convinced him that glassed-in commercial greenhouses will be eliminated in the future by underground rooms heated and lighted entirely by electricity at a moderate cost...
...announced that the Nobel Prize for Medicine for 1922 (not previously awarded) has been divided between Prof. Archibald V. Hill, professor of physiology in University College, London, and Prof. Otto Meyerhof, professor of physiology at the University of Kiel, Germany, for their researches on muscular contraction...
...Prof. Howard R. Mayberry, a psychologist at the University of Chicago, tested 300 men and women students as to their perception of optical illusions, such as two points of light, one moving and one stationary, in a dark room. Whether they were right or wrong, women were, as a rule, more positive of their perceptions, and they were wrong more frequently than the men, who were usually open to conviction...
Forced growth for hothouse flowers and vegetables by the use of electric light during the absence of the sun, may soon be a regular procedure with large florists and nurseries. The Westinghouse Electric and Manufacturing Co. and the Department of Agriculture of Columbia University, Prof. Hugh Findley in charge, learned how to do it in six weeks of experiments at the Peter Henderson greenhouses, Baldwin, L. I. The lights were turned on at 9 o'clock every night; turned off at 2 in the morning, giving five hours of light additional to the normal sunshine. Between time, the plants...
