What are the current and future potential uses of nonhuman primates in research? The National Academies of Sciences, Engineering, and Medicine is examining this question.

More than 4 million people have fled from war and terror in Ukraine. They are among the 70 million forcibly displaced people worldwide. What is brazenly clear is not only the impotence of the existing international apparatus designed to protect them, but also its asymmetries.

Oregon, which legalized medical aid in dying (MAID) in 1997, has dropped the requirement that had limited MAID access to residents of the state. What are the ethical and social implications of this policy change?

As I sit here in my office at the Slovak Medical University in Bratislava, my colleagues are experiencing great moral anguish because of Russia’s invasion of neighboring Ukraine.

Last month, Bloomberg reported on what seems to be the first child born following a new kind of genome-wide screening.

The news has been met with some concerns about the degree of control we may now have over future generations.

Experts in infectious disease and public health warn that the Covid-19 pandemic will be with us until there is an effective vaccine, possibly 12 to 18 months in the future. This situation has given rise to calls for human challenge studies, in which healthy volunteers are injected with an experimental vaccine and then infected with the disease to test the vaccine’s efficacy. Is this ethically justifiable?
