Sample preparation for cryo-electron microscopy (cryo-EM) is a significant bottleneck in the structure determination workflow of this method. Here, we provide detailed methods for using an easy-to-use, three-dimensionally printed block for the preparation of support films to stabilize samples for transmission EM studies.

Studying medullary thymic epithelial cells in vitro has been largely unsuccessful, as current 2D culture systems do not mimic the in vivo scenario. The 3D culture system described herein - a modified skin organotypic culture model - has proven superior in recapitulating mTEC proliferation, differentiation and maintenance of promiscuous gene expression.

Herein we present a method to synthesize ligand-free cadmium sulfide (CdS) nanoparticles based on a unique sulfur copolymer. The sulfur copolymer operates as a high temperature solvent and a sulfur source during the nanoparticle synthesis and stabilizes the nanoparticles after the reaction.
FAQs
Repeated exposure to events a person cannot control can alter both behavior and expectation. Seligman’s learned helplessness research showed that people may become passive and anticipate failure. This mechanism helps explain why interventions may need to address interpretations and behavior together, rather than focusing on behavior alone.
Optimism matters because it counters pessimistic interpretations that can sustain expectations of failure. In the framework described, helping people reframe those interpretations is linked to resilience and more adaptive behavior. The emphasis is not simply on feeling positive; it is on changing how experiences are understood so responses can better support resilience.
His later work examines meaning, engagement, relationships, and accomplishment as contributors to well-being, alongside strengths and conditions that help people thrive. Considering several dimensions prevents well-being from being treated as a single outcome. This broader view also provides concepts that can guide measurement and research across individuals, communities, schools, and organizations.
These ideas describe contrasting psychological directions. Learned helplessness concerns passivity and expectations of failure after uncontrollable experiences, whereas resilience-focused work examines ways to build adaptive responses. Studying both allows psychologists to connect vulnerability mechanisms with approaches intended to strengthen coping, optimism, and constructive behavior in clinical, educational, and organizational settings.
An intervention can focus on three connected tasks supported by the overview: identify pessimistic interpretations, reframe them, and strengthen adaptive behaviors. It can also incorporate resilience-building and attention to meaning, engagement, relationships, or accomplishment when well-being is the target. These elements translate the research into clinical or educational practice without reducing well-being to one measure.
His theories and measurement frameworks inform clinical practice, education, organizational research, and mental-health studies. In clinical settings, they can support work on resilience and pessimistic interpretations; in education and organizations, they provide concepts for examining strengths, engagement, relationships, accomplishment, and well-being. Their value lies in linking psychological theory with assessable outcomes across different environments.
