Considered a landmark moment for mankind, the discovery of fire was the first step out of a primitive world. It lit the world, cooked our food and kept us warm at night.
It’s not all praise for fire though, as it may have also given the world tuberculosis.
Or at least born out of smoke, according to a recent study at the University of New South Wales.
The bacteria’s history traces back for millennia. Mummies from over 4,000 years ago showing signs of the infection in their chests. Tuberculosis spreads from person to person through the air. The mycobacterium that makes up the disease is inhaled and the infection infiltrates the lungs.
