A human embryo that was frozen more than three decades ago has just been born as a baby boy in the United States.

Born in Ohio, the baby has “set the record” and become the world’s “oldest baby” after "being born from an embryo" that was placed in storage before his parents had started primary school, reports The Times.

It describes how Thaddeus Daniel Pierce was born on 26 July to Lindsey and Tim Pierce, who “adopted his embryo” last year. The embryo was frozen in 1994 and one consequence is that the baby has a 30-year-old sister.
