Experiments on insects, higher plants and lower fungi were carried out aboard the biological satellite Cosmos-l129, in Earth orbit, from 25 September to 14 October 1979. The main objective of these experiments was to gain more profound knowledge of the effect of weightlessness on living organisms and to study the mechanisms by which these various organisms(More)
The Cosmos-782 flight from 25 November to 15 December 1975, carried biological experiments designed to study the effects of weightlessness on insects and fish and on gravitropism and growth in several seed varieties. Investigations carried out on Drosophila melanogaster measured the frequency of recessive lethal mutations and the change in genetic distances(More)
Preparatory experiments for the IML-1 (International Microgravity Laboratory) mission to be flown on the Space Shuttle in January, 1992, were performed on a 14 day flight on Biokosmos 9 (Kosmos 2044) in September 1989. The purpose of the experiment was to study the effect of weightlessness on protoplast regeneration. Problems with late access to the space(More)

In the period of 1995-1997 experimental and theoretical studies with various biomechanic objects, i.e. individual cells and cell associations, were performed under changed gravity (0.00001-5 g). Experimental investigations were conducted using clinostats and centrifuges to model effects of hypo- and hypergravity, and aboard space vehicles in real(More)
Possible pathways of the origin and development of adaptive mechanisms in the living systems of various levels of organization are considered from the positions of biomechanics and bioenergetics. Main attention is paid to the specific feature of functional rearrangements in the living organisms during change of habitat, at the stage of their exit from water(More)
The results of studies over many years on various types of unicellular free-swimming organisms in conditions of altered gravity (hyper-, hypo-, and microgravity ranging from 10(-5) to 5 g) were reviewed. Laws governing their growth and functioning under these conditions were established. In general, gravisensing of unicellular free-swimming organisms(More)
Experiments to study the effect of weightlessness on the emergence and development of cell organelles and genetic structures were carried out during 18.5 days aboard the biological satellite Cosmos-936. The experiments were conducted on the fruit fly Drosophila melanogaster Orgeon-R. Their purpose was to investigate possible chromosomal aberrations and gene(More)
The present paper is a review of the experimental investigations published in the literature and performed by the authors on space vehicles. The paper also gives an analysis of theoretical concepts concerning gravitational effects on the cell. Taking this into account, the authors put forth a hypothesis that free-living unicellular organisms are indifferent(More)
Populations of dark-grown protonemata of moss Ceratodon purpureus wt-4 (Germany) and wt-U (Ukraine) were rotated on clinostat or flown in space (experiment "Protonema" aboard Bion-11, December 24, 1996-January 7, 1997) to determine the effects of altered gravity on orientation of protonemata growing filaments. Protonemata had been cultivated 8 days in(More)
The paper analyses and summarizes the experimental results obtained by the authors and data accumulated in the literature during recent years in order to reveal the general regularities of the growth, distribution and behavioral parameters of the cells under conditions of reduced gravity ranged from 10(-5) to 5 g. It is indicated that an intensity of(More)
