Comparison in the motility of flies exposed to simulated and real microgravity. (A) Motility in the magnet (simulated microgravity and hypergravity) expressed as global activity in cm2/10 min. Activity is almost 3× in unloaded conditions and 0.5× in 2g* simulation. Average activity of 20 periods of 0.5 min is indicated with the bars (statistical significance *p<0.05 has been calculated with the Bonferroni–multiple ANOVA method). (B) Magnetic levitation data (Hill et al.,
2012) shows the same trend as real spaceflight mission data obtained from the IML2 shuttle (Benguria et al.,
1996) and the AGEing Cervantes mission (de Juan et al., 2007) experiments as resumed in part (B); motility increased from 3 to 9 times under real microgravity conditions depending on Drosophila selected strains exposed [SL, short life strain, comparable to wild type; GA, altered gravity strain; LL, long life strains; y, young (<2-week-old imagoes); m, mature].
