InterPLAY: A Framework to Describe Play and STEM Engagement at Exhibits for Young Children

Curator: The Museum Journal, EarlyView.
ABSTRACT Play‐based STEM learning at exhibits is a feature of children's museums and science centers; yet little is known about how these exhibits support young children's STEM engagement. This study developed and tested the interPLAY Framework to describe play‐based STEM engagement at exhibits for young children.

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Narrative reconstruction of the self: Living funerals as rituals of trauma and transformation

The Australian Journal of Anthropology, EarlyView.
Abstract Living funerals mark a radical reconfiguration of contemporary engagements with mortality, transforming death from an imposed ending into an actively authored narrative. This study examines the practice in Hong Kong's hybrid sociocultural landscape, where traditional Chinese death rituals collide with neoliberal selfhood and globalised ...

Leveraging Multimodal Large Language Models to Analyse Student Exploration Behaviours in Educational Game Environments

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Video data provides rich opportunities to examine student behaviour in game‐based learning environments, capturing not only observable actions but also subtle indicators of cognitive engagement. However, traditional video analysis is labor‐intensive, and current applications of AI to this task are limited by models trained on ...

The Interplay of Teacher Agency and TPACK in AI‐Integrated Science Education: Insights From Exemplary Practice Cases

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Teacher agency plays a pivotal role in technology‐enhanced instruction, yet empirical evidence connecting agency to the practical enactment of specific components of TPACK remains limited. In particular, the intersections between teacher agency and TPK/TCK as enacted practices warrant closer scrutiny.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 644-671, July/August 2026.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Comparative Thermodynamic and Preliminary Performance Assessment of N₂O, Gaseous O₂, and LOX for a 1 kN Hybrid Rocket Engine

Aerospace
Hybrid rocket engines offer a compromise between safety, controllability, and performance, making them attractive for small-scale propulsion systems. However, oxidizer selection remains a critical early-stage design decision that cannot be determined ...
