Mitochondrial replacement techniques: US-style

15 February 2016 - by Dr Peter Mills

The US NAS has published a report on the ethical, social and policy considerations relating to mitochondrial replacement techniques.

The case against human cloning

28 September 2015 - by Brendan Foht

Compared to the frenzy over human cloning a decade ago, in recent years the issue has received very little political attention. But as the ongoing fights over CRISPR and mitochondrial replacement show, some of the underlying debates are still with us... [Read More]

Cutting-edge technology and mitochondrial diseases - where is the limit?

27 July 2015 - by Dr Dusko Ilic
