Chemist David Liu explains how gene editing is paving the way to treating and even curing certain genetic diseases.
Gene editing revolutionised science.
Gene editing promises everything from treatments for serious conditions like sickle cell disease to the resurrection of the dodo.

Scientific and public uproar resulted when the Chinese scientist announced the births of the first human babies with heritable edits to their genes. A new documentary reexamines the saga.
The biotech sector uses climate change as an urgent argument for more funding and fewer regulatory hurdles. But the urgency of climate change raises the risk of superficial claims and actions.
While resurrecting dinosaurs may not be on the docket just yet, gene drives have the power to alter entire species.

As genetic engineering and DNA manipulation tools like CRISPR continue to advance, the distinction between what science ‘could’ and ‘should’ do becomes murkier.
The rapid rate of species declines means we should trial potential solutions before it’s too late.
Rabies, for example, is a naturally occurring ‘zombie’ disease.
New research in fruit flies elucidates how the genes that direct animal body shape work.

Hox genes make sure all your body parts grow in the right place. Understanding how they work can reveal the process of evolution and lead to potential treatments for congenital birth defects.
Field trials of genetically edited crop plants are to be allowed in England under new government proposals.
Catherine Price, sociologist, and Nicola Patron, synthetic plant biologist, discuss the promises, dangers and concerns around gene edited and GM crops.
Crystal jellyfish contain glowing proteins that scientists repurpose for an endless array of studies.

Three pioneering technologies have forever altered how researchers do their work and promise to revolutionize medicine, from correcting genetic disorders to treating degenerative brain diseases.
A global treaty bans research or stockpiling of biological weapons — but allows bioweapon defense planning.

The sketchy history of international efforts to control bioweapons suggests that nations will resist cooperative monitoring of gene hacking for medical research.
The achievement didn’t live up to the hype, but it has illuminated new areas of ‘genetic dark matter’.
Using ‘base editing’, researchers have cured progeria in mice. This genetic syndrome causes premature ageing in humans – those with the disease usually don’t live past the age of 13.

Plant scientists hope to avoid a repeat of the GM foods debate from two decades ago.
Jennifer Doudna and Emmanuelle Charpentier have been awarded the Nobel prize in Chemistry for their revolutionary work on ‘gene scissors’ that can edit DNA.

The tools to rewrite the genetic code to improve crops and livestock, or to treat genetic diseases, has revolutionized biology. A CRISPR engineer explains why this technology won the Nobel, and its potential.
CRISPR enables editing DNA with unprecedented precision.

Most scientific discoveries these days aren’t easily ascribed to a single researcher. CRISPR is no different – and ongoing patent fights underscore how messy research can be.
Our approach to controversial technologies shouldn’t be guided by scientists alone, nor by peddlers of misinformation on social media. A citizens’ assembly could walk the line between the two.
Introducing healthy genes to replace defective ones is the essence of gene therapy.
The immune system is trained to destroy viruses, even when they carry therapeutic cargo as is the case in gene therapy. Now researchers have figured out how to dial down the immune response.
