Caption: A Drosophila fly was infected with a fungus. UC Davis experiments with flies raised on the Space Shuttle, on Earth and under high gravity in a centrifuge show that gravity affects the Toll receptor pathway responsible for fighting this infection. Toll receptors are also important for immunity in mammals including humans.
