Argumentation in science education as a systemic activity: An activity-theoretical perspective

, 2016
The main aim of the paper is to show that argumentation in primary science education can be exhibited not only as a collective activity, comprising of a series of discrete teaching and learning actions, but also as a systemic activity.

Cocktail of Food Science and Argumentation: Shaken or Stirred for Learning?

LUMAT, 2013
Food science like other domains of science poses challenges to teachers and learners. A significant challenge concerns the articulation in the learning environment of the evidence and justification for the knowledge claims made about food.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Developing scientific argumentation strategies using revised argument-driven inquiry (rADI) in science classrooms in Thailand

Asia-Pacific Science Education, 2019
Scientific argumentation skills are important for students for expressing their opinions, making decisions and solving problems in daily life. Previous studies have focused on students’ scientific argumentation skills, but few studies have proposed an ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
