Explanation

The first person to receive a heart transplant from a genetically modified pig has died two months after the medical milestone, the hospital that carried out the surgery said on Wednesday. The procedure raised hopes that advances in cross-species organ donation could one day solve the chronic shortage of human organs available for donation, and the team behind the operation say they still remain optimistic about its future success. David Bennett, 57, received his transplant on Jan 7 and passed away on March 8, the University of Maryland Medical System said in a statement.
