Issue 37 – Mass extinctions

Feb-Mar 2011

Without the cataclysmic impact that killed the dinosaurs 65 million years ago, humans would not be here. A 23-page impact special in this issue of Cosmos Magazine explores that fateful day with a blow-by-blow account, discover how meteorite impacts have shaped evolution and find out where the biggest bang in the Solar System took place. Also in this issue: why the Internet is making you smarter; how new discoveries deep underground may rewrite the books on physics; and see the prototype nanobots that may one day perform surgery inside you. Plus, we'll take you to the deserts of Syria where scientists are racing to feed the world in 2050, and travel to the cold, misty forests of Brazil in search of the last jaguars.
