Medical research has a dark history of human experimentation in Nazi Germany. And we're still uncovering the extent of the horrors.
Four months ago a researcher claimed he had used the tool CRISPR to edit the genomes of twin girls. Now prominent researchers and ethicists are calling for a temporary halt to this sort of work.
International standards ban publication of research that involves any biological material from executed prisoners, that lacks human research ethics committee approval and that lacks consent of donors.
Questions abound about whether the scientist who created the first gene edited human beings took shortcuts in the ethical oversight process. But pedantically focusing on protocol misses the point.
Researchers funded by VW, Daimler and BMW are accused of testing diesel fumes on monkeys and humans.
Next-generation genomic research depends on study participants sharing their biological materials with scientists. But concerns over how that information is protected may hold some people back.
Research should not only benefit the researchers. People who participate in research should also be compensated for the contributions.
On Human Experiments - Should there be compensatio when evidence of unethical research is uncovered long after the event?
The horror of the human experiments by Nazi doctors led to the Nuremberg Code but the international declaration it inspired was watered down for political purposes.
The first part of our series On Human Experiments looks at the parameters of human research and its ethical bounds.
On Human Experiments: what lies behind some of the most shocking human experiments in recent history? Here's a clue: most of it took place during wartime or when war seemed like a real threat.
