Transmission of tuberculosis is linked to historical patterns of human migration

...million people each year. The pathogen is rapidly spreading and evolving multi-drug resistant strains in susceptible regions such as Africa. Interestingly, a strong gender bias in TB infection is reported globally each year; a 70% excess of male TB cases is typical. " M. tuberculosis also has a remarkable a...

Oxygen increase caused mammals to triumph, researchers say

...an domination of the planet. It was the subsequent spreading of shallow seas, the increase in plant life and photosynthesis in addition to the consequent increase in oxygen content that gave the mammals the boost they needed, according to Falkowski.
