2011 World Review In Photos Part II

2011 was a year of global tumult, marked by widespread social and political uprisings, economic crises, and a great deal more. We saw the fall of multiple dictators, welcomed a new country (South Sudan), witnessed our planet's population grow to 7 billion, and watched in horror as Japan was struck by a devastating earthquake, a tsunami, and a nuclear disaster. 

From the Arab Spring to Los Indignados to Occupy Wall Street, citizens around the world took to the streets in massive numbers, protesting against governments and financial institutions, risking arrest, injury, and in some cases their lives. 

Collected here is Part 2 of a three-part photo summary of the last year, covering 2011's middle months.

Rescue swimmers Eddie Mendez (left) and Will Green had found Ostrander in the surf, after the boy was underwater for more than 20 minutes. Ostrander was hospitalized and placed in a medically induced coma for a time, but has since returned home and started the 7th grade. His recovery is still in progress, as he continues to undergo speech and physical therapy. (AP Photo/Damian Mulinix/Chinook Observer) 

Robonaut 2 (R2) waits inside the electromagnetic interference chamber at Johnson Space Center following tests that ensure the robot's electronic systems won't cause problems for other important systems at the International Space Station. Humanoid robot R2 journeyed to the space station onboard the Space Shuttle Discovery during the STS-133 mission, conducting tests, hoping to eventually build a robot helper suitable to assist humans in complex tasks in space or on Earth.
