The Biden Administration Ends Limits on the Use of Fetal Tissue for Research
The decision reverses Trump administration rules and allows scientists to use tissue derived from elective abortions to develop treatments for diseases like cancer and AIDS.

The Biden administration on Friday lifted restrictions on the use of fetal tissue for medical research, reversing rules imposed in 2019 by President Donald J. Trump.
The new rules, disclosed by the National Institutes of Health, allow scientists to use tissue derived from elective abortions to study and develop treatments for diseases including diabetes, cancer, AIDS and Covid-19.
Part Human, Part Monkey Embryos Raise Ethical Concerns Among Scientists
For the first time in history, scientists have created an embryo that’s part human and part monkey. But why?
The news is being met with concern and hesitation across the scientific community. The work was just featured in the journal
Cell, but the reaction hasn’t been what the scientists had hoped.
A New Way to Supply Transplant Organs
The international scientists behind the study say they created the embryos to try and find new ways of growing organs for people who need a transplant.
“This is one of the major problems in medicine organ transplantation. The demand for that is much higher than the supply,” said Juan Carlos Izpisua Belmonte, co-author of the study and a professor in the Gene Expression Laboratory of the Salk Institute for Biological Sciences in La Jolla, CA.

For the first time, scientists have created embryos that are a mix of human and monkey cells.
Cell, were created in part to try to find new ways to produce organs for people who need transplants, said the international team of scientists who collaborated in the work. But the research raises a variety of concerns. My first question is: Why? said Kirstin Matthews, a fellow for science and technology at Rice University s Baker Institute. I think the public is going to be concerned, and I am as well, that we re just kind of pushing forward with science without having a proper conversation about what we should or should not do.

Scientists used stem cells to create a hybrid human-monkey embryo
Chinese researchers have successfully created chimeric embryos by combining human stem cells and monkey blastocysts, a groundbreaking advance with both practical and ethical implications for the future of medicine.
