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.
If crucial medical resources such as ventilators are in short supply, hospitals are supposed to follow ethics protocols to decide who gets treated. But those rules vary, and aren't always clear.
Aiming to find a cheaper, easier way than IVF to ensure human embryos are healthy before implantation, researchers paid women to be inseminated, then flushed the embryos from their wombs for analysis.
Genetic tests can now tell us a lot about our risk for developing Alzheimer's disease. But that doesn't mean people are prepared to receive the information.
