Earth as Alien Planet

I love stuff like this, soldiers laying in a battlefield with wounds found they survived better if their wounds had been glowing overnight – 

“During the 2 days of fighting at the Battle of Shiloh in 1862, over 16 000 soldiers lay wounded in cold, muddy fields waiting for rescue.   During the night, some of the men noticed that their open wounds began to glow in the dark  A  greenish blue glow”

“The men had no explanation for this strange glow.  Doctors discovered that soldiers who had reported seeing their wounds glow had a much higher chance of survival than soldiers who did not.”
