Conversations Before Midnight Wed., November 12, 2025 | 6:00 PM — 9:00 PM The Blackstone Hotel 636 South Michigan Avenue Chicago, IL 60605 United States Sponsored By: Bulletin of the Atomic Scientists Each year, the Bulletin of the Atomic Scientists convenes an exceptional community of leaders — in science, policy, business, and philanthropy — for an evening focused on the most urgent issues shaping our shared future. Conversations Before Midnight is not simply an event; it is a space for serious, solutions-focused dialogue on the defining challenges of our time: nuclear risk, climate change, and disruptive technologies. This annual gathering reflects the Bulletin’s unique mission: to connect evidence-based research with public engagement, and to translate scientific insight into societal impact. Attendees are not passive observers — they are partners in shaping responsible paths forward at a moment of global consequence.
