Daily SumUp

A US woman has become the world's longest-living recipient of a pig organ transplant, after living healthily with her new kidney for 61 days.

Towana Looney, 53, received the experimental organ in November after spending nearly eight years on the organ transplant list with little hope of finding a match.

She donated a kidney to her mother in 1999 but developed kidney failure several years later after a complication during pregnancy.

But now, she said she feels like "superwoman" after the successful transplant, laughing about outpacing family members on long walks around New York City.
