Cover Story: Gene Drives: A Way to Genetically Engineer Populations
Gene drives occur when a bias in the mechanism of inheritance spreads particular genetic variants through a population. Developments in gene-editing technology now make it possible to construct gene drives that address problems in health, agriculture and conservation.
Feature: Driving Mosquitoes out of Town
Existing techniques to control mosquito-borne diseases are coming up short. Can gene drives offer hope to the millions affected?
Feature: Gene Drives for Conservation
Gene drives may provide a novel tool to counteract seemingly unstoppable threats to global biodiversity.
Feature: The Future of Pest Control Lies Within (the Pest)
Gene drives could improve global food security by turning pest biology against itself.
Feature: Gene Drives: A Fork in the Road for the GMO Debate
What are the moral and ethical concerns about gene drives, and how should the technology be regulated?
Feature: It’s Not Just About “The Science”
Female scientists and health professionals have revealed that opposition to genetically modified food is less about “the science” and more about perceived conflicts with personal values.
Expert Opinion: Food Standards Authority Defends GM Safety
Earlier this year, a scientific review raised concerns that double-stranded RNA molecules produced in new genetically modified crops could pose a risk to human health. Food Standards Australia New Zealand (FSANZ) has responded to the claims by Heinemann et al. (2013) that this gene silencing technology is entering the food supply without adequate scrutiny.
Expert Opinion: Genetic Sprays Use RNA Interference to Combat Pests
Monsanto is developing sprays to control weeds and insect pests by temporarily altering their genetics through RNA interference as an alternative to developing new GM crops, and could also be used to introduce traits like drought resistance.
Expert Opinion: Second Genetically Modified Human Embryos Created
A second case of gene editing of human embryos has attempted to introduce resistance to HIV infection, but only four of the 26 embryos were modified successfully.
Naked Skeptic: Abuse of a Sound Principle
The Precautionary Principle has been abused in debates about climate change, vaccination and genetically modified food.
Simon Says: GM Support Going Stale
Australians are increasingly divided in their support for genetically modified crops and foods.
Up Close: Genetic find and replace with CRISPR: Technology that will revolutionize medicine and agriculture
Molecular biologist Prof Jacob Corn describes how gene editing is carried out with CRISPR-Cas9. He explains why this technology has the potential of revolutionizing the treatment of diseases such as sickle cell anemia and malaria. Besides human health, CRISPR-Cas9 can also contribute to improving agriculture and, consequently, food security. Jacob also discusses the possible ethical challenges posed by the widespread application of gene editing.
Up Front: A New Twist in the DNA Revolution
Gene drives take genetic modification to the population level, with applications in health, conservation and agriculture, but there are also practical and ethical concerns.
Online Feature: WA's court verdict on GM crops is a dose of common sense
The WA Supreme Court has dismissed an organic farmer’s claims for damages from his neighbour’s genetically-modified canola crop.
