Ethics dumping, placebo buttons and why climate change is a threat to national security

AS THE controversial story of the editing of the genomes of two babies in China unfolds, we ask how can science be more ethical—and how to tackle “ethics dumping”. We also look at how how environmental factors can influence the national security of countries affected by climate change. Finally, what is a placebo button? Host Kenneth Cukier explores this pressing phenomenon. This episode is 16 minutes long.
