Black swans from the red planet—Could NASA bring back “mirror life” from Mars? NASA and the European Space Agency plan to bring samples back from Mars. Could they harbor a type of life that scientists warn could trigger mass extinctions on Earth?

“With perhaps a 50-50 chance that any #Martianlife developed from a #mirrorbiology, the return of samples from #Mars has transformed from a scientific opportunity to a potential #existentialrisk.” thebulletin.org/2025/11/mirr...

#Mirrorbiology is an emerging field that explores the creation and behaviour of mirror-image biological systems.

The advisory group on #ResponsibleScience and #DualUseResearch met at @who.int HQ in Geneva this week--look out for forthcoming reports on #AI-Biotech Convergence and Responsible Publishing, and Q&As on #MirrorBiology, research with pandemic risks, and military #biodefence research.

Tune in today at 12PM ET for our webinar focused on #MirrorBiology.
