Fruit flies detect cancer | ScienceBlogs

New research published in Science Reports by Strauch et al., shows that fruit flies can tell the difference between cancerous and healthy cells. The researchers recorded calcium patterns indicative of neuronal activity that was stimulated in response to various odors emitted by healthy and cancerous cells. Because cells with cancer differ metabolically from healthy cells, they emit different volatile compounds that can be detected by olfactory receptor neurons on the antennae of fruit flies.

What is Photoelectron Spectroscopy?

Photoelectron spectroscopy involves the detection of the kinetic energies of photoelectrons emitted following an ionization event. If it is assumed that the emitted photoelectrons do not undergo any collisional event post-ionization, the kinetic energy of the detected electron should be equal to the binding energy of the orbital it was ejected from.
