Flies usually avoid cocaine – it tastes bitter. But when bitter-sensing neurons are switched off, they learn to prefer it. This new model could help test human genes linked to cocaine use disorder. 🪰💊🔬

Bitter sensing protects Drosophila from developing experience-dependent cocaine consumption preference
Cocaine is an addictive psychostimulant, and the risk of developing cocaine use disorder (CUD) is highly heritable. Little is known about the specific genes and mechanisms that lead to the development of CUD, and there are currently no FDA-approved pharmacotherapies…

A new study has found that genetic signatures of assortative mating, where people pair up with partners who share similar traits, have grown significantly stronger among more recently born generations in the United States, particularly regarding educational attainment and smoking habits.

The genetic signature of assortative mating appears to be growing stronger in the United States
Couples tend to resemble each other in schooling, drinking, and smoking. A study of hundreds of thousands of people suggests this matching leaves a measurable imprint in the genome, one that may have grown stronger in recent American generations.
