Form flows function: Learner‐centered game Re‐design in a STEM classroom

open access: yesBritish Educational Research Journal, Volume 52, Issue 5, Page 3322-3340, October 2026.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

The G11-p28 derivative of p28 does not form intracellular inclusions, but is trans-coalesced by untagged p28 and p28-mCherry.

open access: yes, 2017
As in previous experiments, a p19-expressing construct was present in all infiltrations. (A) Diagram of the constructs used. Note that the N-terminal G11 tag of G11-p28 does not fluoresce by itself, but becomes fluorescent in the presence of G1-10 ...

Designing γ‐TiAl Alloys With Refined Twin‐Lamellar Microstructures via Machine Learning‐Driven Phase‐Field Methods

open access: yesMaterials Genome Engineering Advances, Volume 4, Issue 4, October 2026.
Dual‐phase γ‐TiAl alloys with refined twin‐lamellar (RTL) structures exhibit optimal strength‐ductility synergy. Here, phase‐field simulations reveal composition‐stress‐dependent refined twin‐lamellar (RTL) microstructure evolution. Machine learning (CatBoost + NSGA‐III) trained on phase‐field images predicts optimal RTL‐stress‐composition design space.
