Scientists discovered some bacteria can cut the DNA of invading viruses as a defence mechanism. They realised they could use this to cut human DNA.

What is CRISPR gene editing, and how does it work?

CRISPR harnesses the natural defence mechanisms of some bacteria to cut human DNA strands. Then the DNA strand either heals itself or we inject new DNA to mend the gap. This is gene editing.

Genome editing of human embryos broadens ethics discussions

A new gene editing experiment explores human development. With this comes new ethical questions: How do scientists acquire embryos and how are their projects approved?

Will CRISPR fears fade with familiarity?

Americans have moved on from worrying about ‘test-tube babies’ – but there are still ethical challenges to resolve as reproductive technologies continue to advance.

Human genome editing: We should all have a say

A team in the U.S. is said to have safely and effectively altered human embryos. The news is a reminder that citizens must be consulted on developments potentially affecting the future of the species.

When evolution and biotechnologies collide

Simple and inexpensive gene-editing technology such as CRISPR has made the creation of genetically modified organisms much easier. But could nature still keep the upper hand?

CRISPR controversy raises questions about gene-editing technique

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.

Safe and ethical ways to edit the human genome

A new report from the National Academies of Science and Medicine outlines conditions that have to be met before gene editing that results in heritable genomic changes can be considered.
Will China be the first to genetically enhance future generations? Jianan Yu/Reuters

The future of genetic enhancement is not in the West

Regulations, funding and public opinion around genetically enhancing future generations vary from country to country. Here's why China may be poised to be the pioneer.

Why we won’t be able to feed the world without GM

The concerns about genetically modified foods are well known. But when we look at population and climate projections, what happens if we don't use them to increase our food supply?
