...which stirred his senses of taste, smell, touch. He examined the brains of beasts and men and concluded, he said in Chicago last week, that for every kind of outside impulse to which man is sensitive there is a particular, infinitesimal cell in his brain. We do not see ultraviolet light or feel infrared heat simply because we have no brain cells to receive those impressions. The impressions which do stimulate our brain affect it by pulsating radiations along distinct nerve cells. Thus "all our sensations rest upon the circulation of electric discharges in cells which stimulate each other...
...trivial in itself, it may lead to sinus disease, bronchitis, pneumonia, heart or kidney disease. Dr. Dochez has been one of the front rank investigators of the common ailment. Last week he reported small progress. Vaccines in general have been disappointing, as have been extra vitamins and exposure to ultraviolet light. Careful analysis of hygienic habits, clothing, and exercise has failed to show that these are important factors in immunity to colds. But there is one clue which Dr. Dochez and his associates, Dr. Yale Kneeland Jr. and Katherine C. Mills, hope may lead them to success. There is "evidence...
...investigators are trying to cure tuberculosis by introducing ultraviolet light to infected body cavities. The artificial sunlight might kill the germs and heal the tissues if it could shine on them. A problem has been how to build a light producer small enough and cool enough to get into the cavities. Last year Drs. John Roberts Caulk & Frank Henry Ewerhardt of Washington University, St. Louis, successfully entered a tuberculous bladder, alleviated it with irradiation. They used a cold quartz generator of ultraviolet light...
...Saturn, through which the comet is at present passing; and it is the gases that are emitted by this cloud which unite with the comet and produce a reflection of unusual brillianey, a light which is made brighter by the presence of the sun. Another theory has been that ultraviolet light surrounds the comet...
...living cells to be studied while whirling at the ratio of 10,000 revolutions a minute. Dr. John Belling of the Carnegie Institution, using photomicrographic equipment, photographed the gene, the tiny particle which is believed to control heredity. Dr. Ralph Walter Graystone Wyckoff of the Rockefeller Institute used invisible ultraviolet light to photograph the growth of living cells under the microscope...
