US actor Tony Sirico, best known for portraying Paulie "Walnuts" Gualtieri in "The Sopranos," has died aged 79, his family and a former castmate said on July 8. 

Sirico played minor mobster roles in television and film for decades before being cast in his fifties as the eccentric and sometimes brutal Paulie on HBO's hit show -- becoming one of the series' most memorable characters.

A 34-year-old British scientist who was found dead at the bottom of a steep ravine on Wednesday on the eastern Aegean island of Ikaria, most probably died as a result of a fall rather than foul play, an expert said on Thursday.
