This year’s Nobel Prize in Chemistry has been awarded to a trio of researchers including Omar Yaghi, a Jordanian American chemist at the University of California, Berkeley, for pioneering work on porous molecular structures that can be used to trap greenhouse gases and other pollutants. Yaghi was born in Amman to Palestinian refugee parents who fled their homes in Gaza in 1948, when those establishing the state of Israel violently expelled over 700,000 Palestinians.
