Nobel Laureates

Meet the 2011 Nobel Laureates

Yemeni activist Tawakkul Karman, one of three recipients of the 2011 Nobel Peace Prize, at her tent in Change Square in Sanaa, Yemen. Karman's Nobel Peace Prize draws attention to the role of women in the Arab Spring uprisings; they have rebelled not only against dictators but against a traditional, conservative mindset that fears women as agents of change. Women have participated in all the protests sweeping the Arab world, working both online to mobilize, and on the ground to march, chant and even throw themselves into stone-throwing clashes with security forces side by side with men.

Ellen Johnson-Sirleaf, Liberia's current president and presidential candidate of the Unity Party (UP), is the third Nobel Peace Prize laureate. Liberia's October 11 general election will be the first domestically organised vote since an on-off 1989-2003 civil war and a test for a West African country struggling to close the book on its bloody past eight years after the fighting ceased.

   and US scientist Adam Riess will share the 2011 Nobel Prize in physics. The trio were honored "for the
   discovery of the accelerating expansion of the universe through observations of distant supernovae."

The Royal Swedish Academy of Sciences said American Perlmutter would share the 10 million kronor ($1.5 million) award with US-Australian Brian Schmidt and US scientist Adam Riess. Working in two separate research teams during the 1990s, Perlmutter in one and Schmidt and Riess in the other, the scientists raced to map the universe's expansion by analyzing a particular type of supernova, or exploding star.

   Canadian-born scientist Ralph Steinman died three days before he was awarded the Nobel Prize in Medicine for "his discovery of the dendritic cell and its role in adaptive immunity". Steinman died of pancreatic cancer at the age of 68, having extended his life using a kind of therapy he designed. This is the first time in history, that the Nobel Prize, which is never awarded posthumously, will go to a dead person. (AP Photo/Mike Groll)
