Science Results for Everyone
In sci-fi movies, people spend years in sleep-like states during space travel. Reality may be less dreamy. Researchers tested long-term dormant states in space in invertebrates and plants and found that the stress of space caused decreased reactivation and weakened embryos post-dormancy in a fish species. Other test subjects showed decreased growth and possible loss of reproductive ability, and some had changes in gene expression. These negative effects remained when dormant cells were reactivated. The results indicate that more in-depth studies on how spaceflight affects dormant organisms are needed before we start sleeping our way through the cosmos.

Experiment Description

Research Overview
Information Pending

Description
Study of the capability of long-term storage of resting forms of animal organisms, possible microecological system components in space flight conditions. Determination of the percentage of reactivated specimens. Trade off analysis of reactivated specimens of flight and reference experiments. Study of genome areas (DNA) responsible for diapause formation and depth. Investigation of the nucleotide sequence and synthesis in the corresponding genome areas of proteins-adaptagens and signal proteins involved in the stress response and morphogenesis.
