How the next Congress decides to handle the issue will affect the science, ethics, and financing of genome editing for decades to come

Questions concerning the potential effects on fetal health and successful pregnancy for those infected with SARS-CoV-2 remain largely unanswered

When and how animal ancestors made the transition from single-celled microbes to complex multicellular organisms has been the focus of intense debate

The ability to select for traits that are brought about by multiple genes—rather than genetic diseases caused by a single mutation—is more far off and complicated than most people probably realize

Recent study sheds new light on how our epigenetics can regulate genes, some of which are linked to cancer development later in life, over large evolutionary distances

When it comes to modeling the early developmental processes of the human embryo, things become complicated

Sperm samples stored for up to 15 years analyzed

How life's first step happens has long fascinated developmental biologists

More rigorous standards must be established to guide further research efforts in germline gene therapy, scientists argue
