Italy's Giorgio Parisi on Tuesday won a share of the Nobel Prize for Physics. Rome-born Parisi, 73, won the prize for his research on complex systems. A theoretical physicist at Rome's La Sapienza University and the National Nuclear Physics Institute (INFN), Parisi is also vice president of the Accademia dei Lincei.

He shared the prize with Syukuro Manabe of Japan and Germany's Klaus Hasselmann. The two researchers won for their work on climate models and global warming. Italy has now won 20 Nobels including 12 for science and two for women: Grazia Deledda for literature in 1926 and Rita Levi Montalcini for medicine 60 years later in 1986.
