The images mean scientists no longer have to dissect the flies by hand to observe how genetic changes influence the loss of brain cells.Photograph: Leeanne McGurk/Medical Research Council and PLOS ONEA 3D image of a fruit fly generated using optical projection tomography. Scientists hope the technique will reveal information about neurodegenerative diseases in humans such as Alzheimer's.Photograph: Leeanne McGurk/Medical Research Council and PLOS ONE
