The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

Evidence for Mass-dependent Evolution of Transitional Dwarf Galaxies in the Virgo Cluster

The Astrophysical Journal
The presence of transitional dwarf galaxies in cluster environments supports the hypothesis that infalling star-forming galaxies are transformed into quiescent early-type dwarf galaxies (ETdGs) through environmental effects.

Feedback by Massive Black Holes in Gas-rich Dwarf Galaxies [PDF]

, 2017
Could there be intermediate-mass black holes in essentially all old dwarf galaxies? I argue that current observations of active galactic nuclei in dwarfs allow such a radical hypothesis that provides early feedback during the epoch of galaxy formation ...

Deciphering the role of epistemic injustice in school‐based citizen science: Sources, implications, and possible ways for mitigation

Journal of Research in Science Teaching, Volume 62, Issue 5, Page 1350-1387, May 2025.
Abstract Participation in citizen science, a research approach in which nonscientists take part in performing research, is a growing practice in schools. A main premise in school‐based citizen science is that through their participation, students and teachers make meaningful contributions to the advancement of science.

Star Formation History of Dwarf Galaxies in Cosmological Hydrodynamic Simulations

Advances in Astronomy, 2010
We examine the past and current work on the star formation (SF) histories of dwarf galaxies in cosmological hydrodynamic simulations. The results obtained from different numerical methods are still somewhat mixed, but the differences are understandable ...

Resonant stripping as the origin of dwarf spheroidal galaxies [PDF]

, 2009
Dwarf spheroidal galaxies are the most dark matter dominated systems in the nearby Universe and their origin is one of the outstanding puzzles of how galaxies form. Dwarf spheroidals are poor in gas and stars, making them unusually faint, and those known as ultra-faint dwarfs have by far the lowest measured stellar content of any galaxy.

Modelling chemical abundance distributions for dwarf galaxies in the Local Group: The impact of turbulent metal diffusion [PDF]

, 2017
We investigate stellar metallicity distribution functions (MDFs), including Fe and α-element abundances, in dwarf galaxies from the Feedback in Realistic Environment (FIRE) project. We examine both isolated dwarf galaxies and those that are satellites of

The potential of red‐fleshed apples for cider production

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 3, May 2025.
Abstract Cider quality is influenced by numerous factors relating to the apples used during production. While extensive research has been done to explore the phenolic content, sensory quality, and storage stability of various apple products, the domain of fermented apple products, such as ciders, remains underrepresented. Red‐fleshed apples (RFAs) have
