The effect of cosmic-ray shielding on the ultraweak bioluminescence emitted by cultures of Escherichia coli.

Neither the growth of Escherichia coli nor its associated luminescence was significantly affected when cultures were shielded from the soft component of cosmic rays. The study included experiments in which the cultures were shielded intermittently during their two periods of luminescence emission and experiments in which the cultures were continuously shielded throughout their entire growth cycle. These results do not support previous suggestions that the ultraweak bioluminescences from living organisms might be cosmic-ray-excited fluorescences induced in certain biological molecules synthesized during the various stages of growth.

Stimulating effect of space flight factors on Artemia cysts: comparison with irradiation by gamma rays.

The Artemia cyst, a gastrula in dormant state, is a very suitable material to investigate the individual effects of HZE cosmic particles. Monolayers of Artemia cysts, sandwiched with nuclear emulsions, flew aboard the Soviet biosatellite Cosmos 1129. The space flight stimulated the developmental capacity expressed by higher percentages of emergence, hatching, and alive nauplii at day 4-5. A greater mean life span was reported in Artemias developed from Artemia cysts hit by the cosmic heavy ions. On Earth, Artemia cysts were exposed to 1, 10, 100, 200 and 400 Gy of gamma (gamma) rays. A stimulating effect on developmental capacity was observed for 10 Gy; the mean life span was significantly increased for this dose. These results are discussed in comparison with previous investigations performed on Earth and in space.

[The effect of cosmo-helio-geophysical factors on the agglutination of bacteria in vitro].

A correlation between intensity of neutronal component of cosmic rays and typhoid bacteria agglutination was revealed. Agglutination speed dependence on season, polarity of interplanetary magnetic field, geomagnetic storms, Sun's revolution was shown. An assumption is made about an important role of the magnetic fields in the phenomena observed.
