Scientists have managed to wipe out a population of mosquitoes in a laboratory using a type of genetic engineering known as a gene drive. The intervention prevented the females from reproducing and caused the entire population to die off. Scientists hope the method can be transferred from the lab to the real world to tackle mosquito populations that spread diseases like malaria, as Henry Ridgwell reports.
An observatory in Barrow, Alaska, the most northerly astronomical outpost in the U.S., has become a key scientific instrument in studying climate change. Established in 1973, the Barrow Observatory is staffed year-round by two researchers who measure and track changes in air quality and weather, while also acclimating with local traditions. Natasha Mozgovaya traveled to Barrow, now officially called Utqiagvik, its Inupiaq name, to see what life is like in one of the coldest places in the world.
