Episode description

In November 2018, a Chinese scientist stunned the world by announcing that he had successfully edited the genes of two embryos. These twins had their DNA changed to try and make them resistant to HIV, it was only successful in one.

Shock and outrage followed as the media proclaimed that the age of the designer baby had arrived and we had opened a door that could never be closed. The Chinese government ordered an inquiry and the scientist rumoured to be put under house arrest.

For many in the genetics community it had only been a matter of time until this happened. The game changer came in the form of a new technology known as CRISPR, a relatively simple and cheap way of changing genes. One that could be used in fertility clinics worldwide.

Does this now mean an age of elite super humans could be born to the ultra-rich? Children created with superior traits, tall, beautiful and hyper intelligent.

The truth is not so simple. This week we ask: should we fear ‘designer babies’?
