This retrospective analysis of a long‐term community‐based participatory research (CBPR) process spans over two decades of work with Alaska Native communities. A call to action from Alaska Native leadership to create more effective strategies to prevent and treat youth suicide and alcohol misuse risk initiated a response from university researchers. This CBPR process transformed into a collaborative effort to indigenously drive and develop solutions through research. The People Awakening project started our team on this translational and transformational pathway through community intervention science in the Central Yup'ik region of Alaska. We examine more deeply the major episodes and their successes and struggles in maintaining a long‐term research relationship between university researchers and members of Yup'ik Alaska Native communities. We explore ways that our CBPR relationship has involved negotiation and engagement with power and praxis, to deepen and focus attention to knowledge systems and relational elements. This paper examines these deeper, transformative elements of our CBPR relationship that spans histories, cultures, and systems. Our discussion shares vignettes from academic and community perspectives to describe process in a unique collaboration, reaching to sometimes touch upon rare ground in emotions, tensions, and triumphs over the course of a dozen grants and twice as many years. We conclude by noting how there are points where, in a long‐term CBPR relationship, transition out of emergence into coalescing and transformation can occur. Highlights: Long‐term CBPR requires preparation and resolution of crises when we lose key partners over time.Relational cycles are a natural part of a CBPR process and impact upon the research in keys ways.Long‐term community‐based participatory research allows the spirit to come into the science.

Surface elastic instabilities, such as wrinkling and creasing, can enable a convenient strategy to impart reversible patterned topography to a surface. Here the classic system of a stiff layer on a soft substrate is focused, which famously produces parallel harmonic wrinkles at modest uniaxial compression that period-double repeatedly at higher compressions and ultimately evolve into deep folds and creases. By introducing micrometer-scale planar Bravais lattice holes to spatially pattern the substrate, these instabilities are guided into a wide variety of different patterns, including wrinkling in parallel bands and star shape bands, and radically reduce the threshold compression. The experimental patterns and thresholds are enabled to understand by considering a simple plane-strain model for the patterned substrate-deformation, decorated by wrinkling on the stiff surface layer. The experiments also show localized wrinkle-crease transitions at modest compression, yielding a hierarchical surface with different generations of instability mixed together. By varying the geometrical inputs, control over the stepwise evolution of surface morphologies is demonstrated. These results demonstrate considerable control over both the patterns and threshold of the surface elastic instabilities, and have relevance to many emerging applications of morphing surfaces, including in wearable/flexible electronics, biomedical systems, and optical devices.
