As we consider the ethics of human gene editing, we need to understand what can and can't be meaningfully edited.
Should the gathering of experts from around the world that's considering the scientific, ethical, and governance issues linked to research into gene editing ring alarm bells?
New genetic technology could change the DNA of entire species to prevent them from spreading diseases.
The recipients of this year's Nobel Prize for Chemistry showed that DNA is far from static. Rather, it is bombarded by damaging forces, but our bodies know how to repair these precious strands.
Despite predictions, the CRISPR/Cas9 gene editing technique didn't win the Nobel Prize. But with the technology nevertheless taking off, it is time we start having an informed public debate about it.
Until more is understood, it's sensible to limit experimentation that would make changes to germ line cells that would be passed on to future generations.
Leading researchers have called for a ban on using a precise gene-editing technology on humans. How can CRISPR advance science and why is it raising concerns?
A naturally-occurring system discovered in bacteria holds promise as a way to fight pathogens – very specifically and without the risk of antibiotic resistance.
