Effects of Weightlessness on the Embryonic Development and Aging of Drosophila (COS 782-10)
Principal Investigator
Research Area:
Developmental biology
Species Studied
Scientific Name: Drosophila melanogaster Species: Fruit fly


All living organisms have evolved under the influence of Earth's gravity, and, therefore, it is generally assumed that gravity has played a role in shaping structure and function. Previous laboratory work has documented that the aging process of Drosophila is strikingly sensitive to altered environments, such as temperature changes and rotation in a clinostat. This study focuses on the aging process of fruit flies which developed and spent their first days of life in space.
