Differences between gut flora and genes from konzo-prone regions of the Democratic Republic of Congo (DRC) may affect the release of cyanide after poorly processed cassava is consumed, according to a study with 180 children. Cassava is a food security crop for over half a billion people in the developing world. Children living in high-risk konzo areas have high glucosidase (linamarase) microbes and low rhodanese microbes in their gut, which could mean more susceptibility and less protection against the disease, suggest researchers.

Using CRISPR, scientists have created a new technology for controlling mosquitoes. The precision-guided sterile insect technique alters genes linked to male fertility and female flight in Aedes aegypti, the species responsible for spreading diseases including dengue fever, chikungunya and Zika.
