TL;DR: The results show that growth in microgravity induces alterations in essential cellular functions, and suggest that the cause of these changes could be an alteration in the cell cycle regulation, at the levels of checkpoints regulating cell cycle progression, leading to a shortened G2 period.

TL;DR: The aim of the Cytos 2 experiment was to study the bacteria's sensitivity to antibiotics cultivated in vitro during the orbital flight, using the bacterial method of minimal inhibitory concentration (MIC).

TL;DR: Different mechanisms involved in weightlessness alteration of microtubules are discussed, including alteration of their self-organization by reaction-diffusion processes, and a mathematical model is proposed, acting on both microtubule and microfilament networks in cell cortex.

TL;DR: It is reported here that continuous exposure to a low dose of γ rays influences the course of spontaneous B-cell lymphoma in SJL mice and provides further support for the absence of harmful effects of a continuous very low doses of radiation.

TL;DR: The results suggest that the transcriptome is finely tuned to normal gravity and that microgravity, together with environmental constraints associated with space experiments, can have profound effects on gene expression.
