3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159
Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

Testing the Bus–DeMeo Asteroid Taxonomy Using Meteorite Spectra
The Planetary Science JournalThe most widely used method to spectrally classify asteroids is the Bus–DeMeo taxonomy. To test how well the Bus–DeMeo taxonomy groups asteroids on the basis of their mineralogy, we have classified ∼1500 meteorite spectra using this Bus–DeMeo system ...

Asteroid secular dynamics: Ceres' fingerprint identified
, 2015 Here we report on the significant role of a so far overlooked dynamical aspect, namely a secular resonance between the dwarf planet Ceres and other asteroids.

Collaborative asteroid photometry of six main-belt asteroids
, 2022 Synodic rotation periods of six main-belt asteroids were derived from photometric observations obtained from 2021 July 21 through November 2 from three observatories situated in Malta and one from Spain. We provide lightcurve rotation periods for (1713) Banchilon, (2232) Altaj, (2458) Veniakaverin, (6681) Prokopovich, (6787) 1991 PF15, and (18863) 1999

Ecosphere, Volume 16, Issue 10, October 2025.Abstract Mass mortality from disease epidemics challenges the resistance and resilience of populations and communities. Assessing the impacts and consequences of such events is crucially dependent on long‐term datasets. In 2013–2016, sea star wasting disease (SSWD) caused population‐wide crashes of the archetypal keystone species, the sea star Pisaster

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).
