It has long been known that there is a complex interplay between genetic factors and environmental influences in shaping behavior. Recently it has been found that genes governing behavior in the brain operate within flexible and contextually responsive regulatory networks. However, conventional genome-wide association studies (GWAS) often overlook this complexity, particularly in humans where controlling environmental variables poses challenges.

In light of long-standing inequities in STEM representation, many universities are now recognizing the value of diversity in higher education. Achieving such diversity involves creating an inclusive campus that welcomes scholars from different backgrounds, not only to foster a healthy intellectual environment, but also to provide role models to aspiring students. Faculty cluster hiring is an emerging practice in higher education, involving cross-campus collaborations to hire faculty working on interdisciplinary research topics.

Commercially viable biofuel crops are vital to reducing greenhouse gas emissions, and a new tool developed by the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) should accelerate their development — and genetic editing advances overall.

Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.

The findings are reported in the Proceedings of the National Academy of Sciences.

A genomic study of Puerto Rico's Africanized honey bees - which are more docile than other so-called "killer bees" - reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees' rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.
