Strengthening health security requires sustained collaboration across governments, institutions, sectors, and borders. The Africa Health Security Index can inform decision-making and prioritize investments in health security to build on progress.

Last night, we hosted a reception and fireside chat to highlight the AHS Index. We convened representatives from African embassies, U.S. government agencies, congressional staff, global health stakeholders, and other partners. Participants engaged in a discussion about health security preparedness, resilience, and opportunities for cross-sector collaboration.

"The integration of AI into nuclear systems is underway. The guardrails, safety, and security frameworks needed to understand and manage the consequences are not.

"AI-enabled biology will keep expanding what’s possible. NTI’s job is to make sure the guardrails expand just as fast, so that promise doesn’t outpace the safety of everyone it’s meant to help. This is the work NTI has done and will continue doing for the next 25 years (and more)," writes NTI's Jake Jordan in our recent blog. ⤵️

As NTI celebrates 25 years of impact, we remain committed to reducing the risks of accidental release and deliberate misuse of life science innovations, strengthening global biosecurity, and guiding efforts to govern emerging technologies.

The 2026 Nuclear Security Index reveals an alarming deterioration in nuclear security conditions in Russia and the United States, the countries that bear the greatest responsibility for global nuclear security as custodians of the vast majority of the world’s weapons-usable nuclear materials. The United States has broken the record for the largest score decline ever, and Russia came in close behind.

Nuclear security is more important than ever, and the 2026 NTI Nuclear Security Index shows governments exactly where to direct their efforts for maximum impact.
