Ethics articles from across Nature Portfolio

Mathematical modelling suggests that it is theoretically possible to reduce risk of common diseases using heritable genome editing. Scientists argue that the technology involves considerable risk and uncertain benefits.

An extensive audit of large language models reveals that numerous models mirror the ‘us versus them’ thinking seen in human behavior. These social prejudices are likely captured from the biased contents of the training data.

Genomic studies of social outcomes raise ethical considerations that heighten researcher obligations to responsibly conduct and communicate their work. A study by Akimova et al. finds that most intergenerational transmission of occupational status can be ascribed to nongenetic factors, and raises questions of how such knowledge should be used and how it might be misused.

We discuss the potential consequences and ethical concerns of polygenic genome editing of human embryos to alter specific variants associated with polygenic diseases, highlighting the possibility of reducing disease susceptibility while exacerbating health inequalities.

Teslin Tlingit knowledge and ecological methods shed light on Chinook salmon in northern river ecosystems, demonstrating links between the health of salmon, riparian forests, bears, and wider social-ecological systems in the Yukon.

In a few decades, gene-editing technologies could reduce the likelihood of common human diseases. Societies must use this time to prepare for their arrival.
