One of the great fears of the early space race was what effect microgravity would have on human explorers — and while we know it won't instantly die when leaving the atmosphere, there's still a lot we don't know about the long term effects of low gravity.

An article published BMC Genomics looked at the effects of magnetically induced weightlessness on the life of the fly. Flies have long been a major part of space research, and remain a key component in understanding its effects to this day.
