Chile’s ALMA telescope makes unexpected discovery, Mexico to launch a satellite, and a protest suspends construction of Brazil’s Belo Monte dam project


Brazil’s Belo Monte hydroelectric project has been put on hold thanks to a new protest by indigenous activists and fishermen who interrupted construction by taking control of trucks and other vehicles, according to the NGO Amazon Watch. The $13 billion dam project was suspended in the past by Brazil’s Supreme Court, but is now back on track to flood 500 square kilometers and displace tens of thousands of people, say environmental activists.
