A punishment is handed down for performing shocking research on human embryos.
- In November 2018, a Chinese scientist claimed he'd flouted ethics and the law to edit genes in human embryos.
- Other Chinese scientists call He Jiankui's research "crazy."
- Three gene-modified babies are now living in China, future uncertain.
Experts are saying it's a "huge step forward for synthetic biology."
- Until recently, the gene-editing tool CRISPR has only been able to make changes within single genes.
- The new tools allow scientists to cut and splice larger chunks of genetic material.
- The findings will likely have major implications for a variety of research fields, and also allow researchers to create synthetic species that can produce molecules not made by natural organisms.
A transformational tool for the future of the world.
- The 'cut and paste' DNA tool CRISPR will one day eliminate deadly diseases.
- The technology will give us the capability to genetically design our children and perhaps one day ourselves.
- CRISPR is already revolutionizing certain fields of medicine.
Do scientists know enough about gene editing to move forward with human trials?
- Doctors used the gene-editing tool in an attempt to treat a 34-year-old patient with sickle cell disease.
- Last year, a Chinese scientist caused major controversy when he used CRISPR to genetically edit two human embryos.
- It's unclear exactly what risks are involved in gene editing.
Chinese scientist He Jiankui edited the genes of two babies to be resistant to HIV, provoking outrage. Now, a new genetic analysis shows why this was reckless.
- The gene-editing technique CRISPR offers major benefits to humanity, but scientists don't believe the field is mature enough for widespread editing.
- For this reason, when Chinese scientist He Jiankui edited the genes of two babies to be resistant to HIV, his work provoked outrage.
- A new study of 400,000 genetic profiles reveals that He's genetic editing did indeed have an unintended consequence.
