Stanley showed. The biggest known, they weigh 17 million times as much as a hydrogen atom, nearly one million times as much as a molecule of water. Left by themselves they are inert. But in contact with living plant or animal material they multiply incessantly. Under some conditions the virus protein molecule changes its inner structure all by itself. It then causes a totally different disease...
...living cell. The high energy carried on the photon swings the electrons of the cell up to correspondingly high energy levels which represent temperatures of 1,000,000°. This lasts for only some .00001 sec., but large protein molecules may be broken up, carbon dioxide and hydrogen given off, and water molecules in the cell oxidized to hydrogen peroxide. The cell may then sicken and die. If it is a cell in the reproductive germ plasm, a mutation or hereditary change may occur...
...Birkhoff system, the hydrogen atom is contemplated as a mixture of two "perfect fluids"-the positive electricity of the nucleus, the negative electricity of the surrounding electron. The disturbance created in the fluids by a particle or light rav from outside can be expressed, very roughly speaking, as though they were water rippled by a falling stone. Furthermore, the expression can be formulated in Relativistic terms. Whether atoms with more than one electron can be crammed into the same mold remains to be seen...
...imaginative persons have suggested that the outpouring of injurious ultraviolet radiation may be so strong that human beings would have to carry umbrellas coated with lead before venturing under the glare of "Nova Cassiopeiae." Other highlights of the astronomers' convention: Nos- 60, 61, 62. In the sun hydrogen, helium, calcium, sodium, carbon, nitrogen, and many another terrestrial element have been identified by comparing the solar spectrum with very clear spectra of substances photographed in the laboratory...
...potassium, sodium and urea balance of the blood; without it man develops Addison's disease and dies. Last week the Mayo researchers announced isolation of a pure crystalline substance which seems to be a close cousin of cortin. The crystal molecule contains 21 atoms of carbon, 28 of hydrogen, five of oxygen. It seems to have the same effect on animals as impure concentrations of the natural hormone, although more of the crystals are required...
