...radiating his poultry pen with ultraviolet light, a farmer near Niles Center, Ill., raised chickens whose flesh was all white meat...
...That ultraviolet rays kill small organisms like bacteria and algae is one of those things which was discovered in the laboratory as a fact of pure science and is now being adapted to practical applications. Last week an article in the Electric Journal, abstracted in the Journal of the Franklin Institute, showed that ultraviolet "bacteria guns" are finding their way into industry...
Just as rats make excellent laboratory animals for nutrition research, mice for cancer and monkeys for poliomyelitis, so ferrets are invaluable to influenza investigators. Ferret reactions were the basis of Harvard's Dr. William Firth Wells's demonstration last month that ultraviolet radiation kills the unknown germ or virus which causes that disease (TIME, Aug. 3). But many doctors think it probable that some infectious agencies change their form in different environments. The question remained: While human influenza could be communicated to ferrets, could ferret influenza be communicated...
...lethal effect of ultraviolet light on whatever causes influenza proved exceedingly difficult to demonstrate. Bacteriologists do not know whether an ultramicroscopic germ causes that disease or whether an ultramicroscopic virus (which may be a living organism or an active chemical entity) is involved. Best means of cultivating that invisible something is in the body of a live ferret. Working with his wife, Dr. Mildred Washington Weeks Wells, and his laboratory associate, Dr. Harold W. Brown, Mr. Wells exposed ferrets to air which had been contaminated by influenza. If the germ-laden air had been exposed to ultraviolet light...
...assumption that ultraviolet light did have this lethal effect a number of U. S. hospitals irradiate the air of their operating rooms with artificial sunlamps. Last week it seemed reasonable to assume that modern theatres, auditoriums, stores and offices which filter and condition their air may also irradiate it with ultraviolet light...
