New clone could solve ethics issue
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

A new cloning technique being developed by scientists linked to Dolly the sheep could sweep away ethical objections to the creation of spare organs and tissues for medical treatments.
The system would create cloned cells without first creating an embryo, sidestepping the moral objections to standard cloning methods. If it works and is accepted, it might lead to treatments for illnesses such as Parkinson's disease.
Dolly the sheep was created when the nucleus of an adult sheep cell was inserted into an egg cell without a nucleus, creating an embryo that was implanted in a sheep and brought to term. That technique would also produce "stem cells" capable of being turned into organs such as kidneys or livers. A patient needing the organ would provide a few skin cells, which would be fused with an egg cell to create an embryo.
A method being worked on by Geron Biomed, a company launched by the team that produced Dolly, would largely dispense with the need for embryos, New Scientist magazine reports today. The technique would use an embryo's stem cell rather than an egg. The stem cells would play the part of the egg, and create the "embryo". The reprogrammed cells would, however, develop directly into the sort of cell that the patient needs.
