New companies are working to commercialize in vitro gametogenesis, or IVG, a technology that could make human eggs and sperm in the lab from any cell in the body.
A Mississippi woman's life has been transformed by a treatment for sickle cell disease with the gene-editing technique CRISPR. All her symptoms from a disease once thought incurable have disappeared.
The Third International Summit on Genome Editing concluded Monday with ethicists warning scientists to slow down efforts to use gene-editing to enhance the health of embryos.
A company formed by Harvard genetics professor George Church, known for his pioneering work in genome sequencing and gene splicing, hopes to genetically resurrect woolly mammoths.
An international team has put human cells into monkey embryos in hopes of finding new ways to produce organs for transplantation. But some ethicists still worry about how such research could go wrong.
Getting the COVID-19 vaccine into most Americans' arms will involve much more than a good supply and logistics. Values such as equity, deep listening, and informed choice are crucial, too.
Exposing people to a potentially fatal disease could hasten understanding of COVID-19 and development of new vaccines and treatments. But the risks of such studies raise serious ethical questions.
Researchers are trying to learn more about COVID-19 vaccines from original study participants. The quest is hampered because many people who first received a placebo shot are opting for the vaccine.
Guidance from the CDC on who should be prioritized to get the COVID-19 vaccine was meant to be flexible and inclusive. But "the attempt to have equity created more inequity," says one researcher.
With vaccine still scarce, and eligibility differing from place to place, some people have easier access to "extra" doses than others. Careful, ethicists warn. Going out of turn is a slippery slope.
