Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
Just because we can edit genes in human embryos, should we?
A world first study shows CRISPR can remove a target gene from early stage human embryos. But with the advance in science come weighty ethical dilemmas.
Controversial gene editing should not proceed without citizen input and societal consensus.
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.
There’s still a way to go from editing single-cell embryos to a full-term ‘designer baby.’
The news may have come as a surprise, but it probably shouldn't have. A bioethics expert walks through how big a deal this announcement is – and what we should be considering now.
Laboratory mice are among the first animals to have their diseases treated by CRISPR.

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.
Precision editing DNA allows for some amazing applications.
Researchers are starting to harness the potential of this much-hyped gene editing technique – with coming applications in medicine, biology and agriculture.
Taking the deadly bit out of mosquitoes.

It's possible to alter the make-up of a species such as a mosquito's ability to pass on the deadly malaria parasite. But we need to consider the pros and cons of such gene editing technology.
Human oocyte in vitro fertilization.
Medical tourism for assisted reproductive technologies raises a host of legal and ethical questions.
CRISPR uses segments of bacterial DNA that can make targeted cuts in a genome when paired with a specific guide protein.
Controversy over a Chinese study that used CRISPR-Cas9 gene-editing technology shows how the West still looks at the East through the lens of Orientalism.
Gene editing technology may soon prevent the formation of sickle-shaped red blood cells in a common and deadly form of anaemia.
A new study has advanced the use of a technique known as 'CRISPR' to treat a common inherited form of anaemia.
Will China be the first to genetically enhance future generations?
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.
Somatic embryogenesis is only used in selected agroforestry industries like sugarcane.
Smarter plant breeding practices are crucial in a world where climate change, deforestation and species reduction are an increasing problem.
Growing human organs in pigs mean they’re doing our dirty work for us.
We're living longer and more ill lives – could we use animals to grow human organs for transplants?
Aedes aegypti mosquitoes are at the center of Zika virus’ spread.
Look beyond transgenic techniques that add new genes to a species. People have used selective breeding techniques to change plants and animals for millennia – why not try them on mosquitoes?
A patent has far-reaching implications for future research.
U.C. Berkeley and the Broad Institute are fighting to control the patents on the revolutionary gene-editing technology. But there's a lot more at stake than just who gets the credit and licensing fees.
Sorting pupae of genetically modified mosquitoes before release to the wild.
Insecticides and mosquito nets only get you so far. Synthetic biologists are ready to take the battle against mosquito-borne disease to the level of DNA – which might spell the insects’ ultimate doom.
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.

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.
