Darwin's famous finches and Venter's marine microbes

Although the Galápagos finches were to play a pivotal role in the inception of Darwin’s theory of evolution through natural selection, he had no inkling of their significance when he collected them during his voyage on the HMS Beagle. Similarly, it is hard to predict the impact the vast amount of mari...

New research shows that flu is a trigger of heart attacks
