That should be useful to stimulate experimentation. It is often assumed that in principle life can arise in a homogeneous medium or at a reactive interface by intrin...
Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted.

We first present a description of the process of DCD and the standard ethical rationale for t...

Adults being tested for familial colorectal cancer were asked whether they want their exome sequencing results disclosed to another person in the event of their death prior to receiving the results.

A reasonable initial increase in life expectancy for today’s generations would be an extra 7 yea...
