Last week two women scientists explained how plants build the cellulose membranes that form cell walls, a process of vital interest to textile technologists. Unable to see how plants manufacture their cellulose, botanists have supposed for a long time that the membranes were laid down in particles too small to be seen under the microscope. Researchers could estimate the molecular weight of cellulose at something around 162. but they could not find the exact weight, or the melting point of the pure substance, or the molecular architecture...
...fibres in strong hydrochloric acid, the cellulose structure came visibly apart under powerful microscopes. The particles, it turned out, had not been too small to see but were hidden by a cementing substance that the acid dissolved. There were football-shaped bodies some .00006 in. long. As the cell wall was built the particles formed compact strands like strings of sausages, and as string after string was laid down on the cell wall they merged so neatly with the gelatinous cement that the structure looked completely homogeneous unless the cement were dissolved. Aware now of the double structure of cellulose...
TIME'S comparison (Oct. 21, p. 56) of a ripe human ovum with a pinhead gives an inadequate concept of the true size of this interesting cell. Actually its diameter is but 1/200 in. This is about the size of the smallest grain of sand that could be seen with the unaided eye. Stated differently, a sphere having the diameter of a common pinhead (1/12 in.) possesses nearly 4,000 times the volume of a human egg. One can compute further that all the eggs needed to replace the present population of the world could be held...
...Public Utility Act were discretionary, not mandatory, Bond & Share might be allowed to live. But should the Public Utility Act survive the test of constitutionality and the Administration survive the test of the next Presidential election. Electric Bond & Share would occupy the No. 1 cell in the industrial death-house...
...monstrosities is the British Empire, an extraordinary "colossus with feet of brass and a head of clay." With its feet of brass it has "trampled down Spain, Holland, France and Germany." Asks Unofficial Observer: "Who will be next? America? Japan? Russia?" This colossus is deathly ill, "weary in every cell," its clay head aching with the problem of preventing war or disorder in Europe which would immobilize the fleet while "the great duel between the white and the yellow races is fought...
