It sounds like the script for a Hollywood movie. The story, first appearing in 2001, begins with a purported civil war legend from the Battle of Shiloh. The legend said that the wounds of some soldiers glowed (faintly) in the dark. Soldiers with these glowing wounds were more apt to survive, giving the phenomenon the name “Angels Glow”. The story ends with two curious teenagers solving the mystery using their science fair project. They identify infection by the bioluminescent bacteria Photorhabdus luminescens (formerly Xenorhabdus luminescens) as the likely cause of the glowing wounds. P. luminescens produces bacteriocins (antimicrobial peptides), which the teenagers attribute to helping keep other infections at bay, resulting in the improved survival rate for the soldiers whose wounds glowed.
The teenagers win. The mystery is solved. The credits roll.
Except life (and science) is rarely as simple as a summer block buster.
