Extracts from unpublished papers on the methods used by a Chinese scientist to genetically modify the embryos of two girls reveal a series of potentially dangerous problems with the procedure and ethical shortcomings. We look at the mechanism behind the formation of our facial features and how this is linked to our evolution, scrutinise the impact of current emissions on global climates and see why lithium, used in batteries and medicines, is now a potentially widespread pollutant.(Photo: He Jiankui, Chinese scientist and professor at Southern University of Science and Technology in Shenzhen.

Molecular scale investigations have identified the mechanism which confers resistance to antimalarial drugs. Researchers hope work to turn off this mechanism could mean cheaper well known antimalarials can become effective once again. We look at the threat to weather forecasting from 5G networks, discuss the origins of much of the technology in our mobile phones and ask what food we’ll be eating in the future and how the past can inform this.Image: Mosquito.
