- Opinion: New human embryo editing advances require tough conversations on ethical boundaries
The article discusses recent advances in human embryo genome editing using CRISPR technology, including a new preprint on base editing from Dieter Egli's lab at Columbia. Despite these scientific developments, ethical questions about the use of such technologies remain unresolved.
- Are we getting to the point where it's safe to gene-edit babies?
A US-based team has achieved promising results using an improved CRISPR method to gene-edit human embryos. However, a significant issue remains unresolved, raising ongoing concerns about safety and ethical implications.
- In a first, scientists precisely edit human embryo genes
Scientists have precisely edited human embryo genes for the first time, a development that has sparked serious debate for over a decade following the invention of CRISPR.
- First precise genome editing of human embryos triggers praise and alarm
A study published in Nature details the first use of 'base editing' in early human embryos. The lead scientist states the technique is not yet ready for clinical use, while critics express concerns about potential commercialization.
- Organ formation in early human embryos captured in spatial cell atlas
A study published in Nature on 27 May 2026 reveals spatial maps of gene expression in whole human embryos during early development, providing insights into molecular programs driving organogenesis. The research captures organ formation across several weeks, advancing understanding of embryonic development.
- Spatiotemporal transcriptome atlas of human embryos after gastrulation
A spatiotemporal transcriptome atlas of whole-human embryos after gastrulation and previously unstudied developmental stages has been published in Nature. The study provides detailed insights into human embryonic development through comprehensive transcriptional analysis.
