Diatoms in the world's oceans exhale more oxygen than all the world's rainforests. These tiny drifting algae generate about 20 percent of the oxygen produced on Earth each year and invisibly recycle gases enveloping our planet.

Viruses are as simple as they are "smart": too elementary to be able to reproduce by themselves, they exploit the reproductive "machinery" of cells, by inserting pieces of their own DNA so that it is transcribed by the host ...
