Kathleen Wren of MSNBC on Lost cities of the Amazon revealed:
Newly discovered traces of ancient roads, bridges, and plazas in Brazil’s tropical forest may help dispel the once-popular impression of an “untouched” Amazon before the Europeans’ arrival. In southern Brazil, archaeologists have found the remains of a network of urban communities that apparently hosted a population many thousands strong. Reporting their findings in the journal Science, published by AAAS, the science society, the researchers say the people who dwelled there dramatically changed their local landscape.
And, Rachel Levin of NBC News on Scientists explore Columbus mystery:
Life was a journey for Christopher Columbus, but the traveling didn’t stop after he died. In the five centuries since the first European explorer to reach the Americas died, his remains have been moved so many times that today both Spain and the Dominican Republic claim to have them. This month, scientists and genealogists will finally test the DNA of the remains in Spain, along with the remains of Columbus’ son and brother, in hopes of resolving the dispute.
Fascinating stuff.
