Cutting and pasting DNA – it’s a bit like fitting in LEGO blocks.

We're not quite there yet but there is already a potential blueprint for editing the human germline.
A snip here, but not a snip there?

The International Summit on Human Gene Editing drew a distinction between editing an individual's body cells and editing germline cells that would pass changes to future generations. Does that make sense?
The cultivation of pig organs for human transplantation carries great risk and promise.
Public attention is focused on whether we should use gene editing technology on embryos, but it could potentially have a bigger and more immediate impact on human health via animal organ donation.

As we consider the ethics of human gene editing, we need to understand what can and can't be meaningfully edited.
Future people would be grateful if their disease is cured, rather than being replaced by a different healthier or non-disabled person.
Experts from around the world are in the US to discuss the scientific, ethical and governance issues linked to human gene editing. Here are five reasons they shouldn't ban research in the field.
The real question is not whether gene editing should be allowed or banned, but how it should be regulated.
The debate about regulating gene editing technology is often couched in polar terms, but understanding degrees of regulation that might be a better approach.
‘Franken Mozzie’ goes under the spotlight.
The ethics of genetically modified mosquitoes and the gene-drive technology that seeks to spread them.
Gene editing allows us to eliminate any misspellings, introduce beneficial natural variants, or perhaps cut out or insert new genes.
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?
Genetic changes to embryos will not only affect the person that embryo becomes but also all their descendants.
While gene editing offers the exciting potential for disease therapies, using it on human embryos opens up a can of worms.
Gene editing has many potential applications that are not discussed enough.
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.
The red Cas9 nuclease protein uses a blue guide RNA sequence to cut yellow DNA at a complementary site.

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.
