Gene drive used to create mosquitoes with potential to stop spread of malaria

Researchers have used CRISPR-Cas9 technology to create a ‘gene drive’ system that spread an anti-malarial gene through a population of the Anopheles Stephensi mosquito, a leading malaria vector in Asia, according to a study in PNAS. Continue reading

Gene-edited micropigs to be sold as pets

A research institution in China is going to sell gene-edited micropigs as pets, according to Nature news. The pigs were originally developed as models for human disease. Researchers used TALENs, a gene-editing tool used to make precise changes to DNA, to disable genes responsible for growth so that the pigs only grow to around 33lbs. Continue reading

Genetically modified diamondback moths reduce pest population and slow resistance to Bt crops in greenhouse trials

A genetically modified version of the diamondback moth, which can devastate cruciferous vegetables, significantly reduced pest populations and decreased spread of resistance to the Bt (Bacillus thuringiensis) bacterial proteins engineered into transgenic broccoli to control pests.

Jurassic World: Can geneticists really resurrect dead species?

The filmmakers behind Jurassic World have updated the franchise’s plot line, with scientists creating a new genetically enhanced dinosaur that (predictably) goes on a rampage. We asked animal biotechnology experts to comment on whether the idea of bringing back and genetically engineering prehistoric species is grounded in reality. Continue reading
