Biology and genetics are terribly, terribly complex. To begin with, you are a lot more than just you. There are roughly ten times as many bacteria cells in the human body as there are human cells ...

It is the beginning of inheritable genetic modification in humans. Should we object to this? On what grounds? It is, after all, the logical next step.

Manipulating genetics has helped mankind in numerous ways. In this article, we consider genetic modification strategies, including genome editing and genetic engineering, the techniques used to ...

Is human genetic modification simply a taboo for the present, or a moral quandary that spans changes in culture and time, asks Stephanie Saulter, author of the new novel "Gemsigns." ...

Research involving genetic modification of human embryos, though controversial, is essential to gain basic understanding of the biology of early embryos and should be permitted, an international ...

That could leave many genetically modified crops unregulated — a worry for those who fear environmental and safety risks or who believe that government vetting is key for broad public acceptance.
