Unraveling the Mystery of Asexual Animal Reproduction: Insights from Fruit Flies and Genetic Engineering

Scientists have successfully induced virgin birth, or parthenogenesis, in fruit flies by altering three genes, providing a genetic basis for this phenomenon. The genetically modified fruit flies were able to pass down their ability to reproduce without mating to subsequent generations. Virgin birth is thought to occur as a survival strategy when a species faces unfavorable conditions, such as a lack of mates. The findings have implications for food security, as virgin births may be becoming more common among crop pests. Modern agricultural practices, including the use of pesticides and homogeneous crops, could be contributing to this phenomenon.

Genetic link found between cannabis use and psychiatric disorders.

A new study from the University of Oslo published in the Lancet Psychiatry, reported a shared genetic basis for cannabis use and psychiatric disorders, including schizophrenia and bipolar disorder. Using advanced statistical modeling, the study shows that the majority of shared variants increase the risk of both cannabis use and developing either schizophrenia or bipolar disorder. These findings may indicate that a subset of the population is at high risk for both cannabis use and psychiatric disorders, based on their genetic propensity.
