Today’s a twofer! Today’s LinkedIn video reminded me of the paper I presented for my pathology class (which was more like a journal club). Both deal with the study of fruit flies (Drosophilia sp.) in space. The video focuses on the role of the flies in studies on the ISS in space, while the paper focuses on a specific study done in 2006 and the probable importance of that study.
Specifically, the paper focused on the way that changes to gravity during the development of Drosophilia sp. resulted in altered immune pathways, leading to specific weaknesses in those flies raised in a microgravity environment. This finding in a model species (one that can be used to illustrate how humans work, but on a simpler scale), may help explain why many astronauts are more prone to illness upon return from space and may also help provide clues for how to counter the impact of gravity on immunity in the future.
