Once genetic lesions for diseases such as cystic fibrosis and haemophilia were identified, the idea of replacing or correcting defective genes grew into what we now call "gene therapy".
Is gene editing compatible with organic farming? A scholar explains the differences between old genetic engineering and CRISPR methods, and why the latter is similar to tradition plant breeding.
Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?
Academics from different disciplines come Head to Head in this series to tackle topical debates.
Mutations in BRCA genes are linked to the early onset of breast and ovarian cancers. But the effect of most mutations is unclear. Now new research can distinguish harmless from dangerous mutations.
For several billion people mosquitoes are more than a nuisance -- they transmit deadly diseases. Now genetic modification may prove the most effective defense against the mosquito, preventing disease.
Basic research can be easy to mock as pointless and wasteful of resources. But it's very often the foundation for future innovation – even in ways the original scientists couldn't have imagined.
CRISPR has been hailed as the an editing tool that can delete inherited mutations and cure disease. But recent papers suggest that the technique may be too dangerous for use in human therapies.
Genetic modification rules now cover gene edited crops but exclude plants bred traditionally with the same properties.
A new study found the Cas9 gene editing scissors don't stop cutting after we tell them to.
GMO crops have been rejected by many countries and consumers. Now, an international team of researchers are creating better crops using DNA editing--without inserting foreign genes into the plant.
A bit of advice for any criminals inspired to try and edit their own genes – it's unlikely to work, and it may present health risks.
One way to make sensors small is to make them out of something that's incredibly small in the first place, such as DNA.
Yes emerging technologies can pose risks - but regulation must focus on outcomes of the technology, not the technology itself.
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.
Universities must train scientists to engage with the ethics of emerging technologies, rather than functioning as cogs in the engine of economic development. Integrating the arts into STEM can help.
Improvements in survival rates for acute myeloid leukaemia have failed to keep pace with other leukaemias. That may be about to change.
Much like the fictitious Victor Frankenstein in Mary Shelley's novel, more and more scientists are running away from their real-life creations.
Only one Canadian has ever received the Nobel Prize for medicine, in 1923. But Canadian discoveries have been essential to stem cell research, gene sequencing and treatments for cancer.
One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients' bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
