The study byCornell University’s Department of Entomology, describes the creation and successful release of gene-edited diamondback moths into an open field setting
Diamondback moths (Plutella xylostella) is one of the main pests for crops in the brassica family which includes cauliflower, cabbage, broccoli, and canola.
Certain populations of diamondback moths have shown very stubborn resistance to synthetic insecticides in many settings around the world.
The idea behind this approach is for genetically-engineered male moths to make their way into the wide world and mate with wild females. They’ll pass on the self-limiting genes, which prevent the female caterpillars from developing normally.
A study has revealed that all humans have a bit of Neanderthal in their DNA, including Africans who had been thought to have no genetic link to our extinct human relative.
Study showed that there were many waves of dispersal out of Africa, some of which led to admixture between modern humans and Neanderthals that we see in the genomes of all living individuals today.
The team also found that previous estimates suggesting that East Asians might have approximately 20% more Neanderthal ancestry compared to Europeans, were wrong and humans on different continents had Neanderthal ancestry similar to each other.
