Welcome to the October-December 2025 i2S News with the latest developments in Integration and Implementation Sciences (i2S).

As well as providing the usual update of tools for tackling complex societal and environmental problems, this issue focuses on the 10^th birthday of Integration and Implementation Insights (i2Insights) toolkit, which we celebrated on November 25^th, 2025.

There are three items related to the 10^th birthday celebrations:

• A refreshing of the aims, an invitation to contribute to a birthday series of blog posts, and a celebration of achievements to date
• An update on the INTEREACH webinar series
• Recognition of new i2Insights Ambassadors.

Seven tools for tackling complex problems were added to either the i2Insights toolkit (https://i2insights.org/) or the i2S-Talks YouTube channel (https://www.youtube.com/@i2S-Talks) in the following main topics: change, communication, diversity, integration, research implementation, stakeholder engagement, systems, teamwork and unknowns.

There is also news from the Global Alliance for Inter- and Transdisciplinarity (ITD Alliance), along with insights into processes and partnerships required to develop a Library Guide for Transdisciplinary Problem Solving.

Feedback and suggestions for i2S News are always welcome!
