That there is vegetation on Mars is a fairly plausible assumption. The reddish hue of the planet used to be ascribed to foliage of that color. A more favored explanation nowadays is chemical absorption of oxygen in the soil-that is, oxidation or "rusting" of the Martian terrain. But the dark patches on the planet's surface grow heavier and more distinct in winter, change from blue-green in summer to chocolate brown in winter. These changes strongly suggest vegetation. The potent chemical compound called chlorophyll is present in all the green plants of Earth, but spectroscopic analysis...
...long time, they said, researchers have known that cancer cells consume an abnormally small amount of oxygen. To find out why, Drs. Davis and Schmitz probed an enormous rat tumor, discovered small pockets of poisonous cyanogen gas along its borders. They also confirmed the presence of cyanogen along the edges of a human tumor. Cyanogen gas, in minute amounts, is a normal cellular waste product, ordinarily passed out into the blood stream through porous cell walls...
Normally present in veins is a white chemical called indigo, which unites with the oxygen in fresh blood and turns blue.* Usually indigo flows with the blood stream to various organs, surrenders its oxygen and turns white again. But when fresh blood reaches tissues bloated with cyanogen, the indigo gets stalled and cannot give up its oxygen. Between the cyanogen and the indigo blue cells are unable to receive any nourishment, and thus, Drs. Davis and Schmitz suggested, the process of tumor development begins. How this vicious circle could be broken they did not venture...
Just as the Brazen arrived on the scene, a masked man had bobbed up from the depths-the first to escape from the foundered submarine. He wore a Davis lung, a contraption resembling the U. S. Momsen lung, consisting of a life belt, an oxygen container, a breathing tube, a nose clip. Half-drowned, he was Captain H. P. K. Oram, commander of the Fifth Submarine flotilla but not of the Thetis. Before he knew that help was at hand he had volunteered to take his chances getting out of the dangerously tilted escape chamber. He and six others, with...
