Short summary
We used 3D-printed building blocks (TotBlocks) in an undergraduate optical mineralogy lab session to illustrate the links between crystal structures and the properties of minerals. Students built mica, pyroxene, and amphibole structures. We observed an improved understanding of cleavage (how minerals break) and pleochroism (how light interacts with minerals), but understanding did not improve with more abstract concepts. TotBlocks hold potential as a teaching tool in mineralogy classrooms.

Short summary
Minerals have complex crystal structures, but many common minerals are built from the same chemical building blocks. TotBlocks is a novel, open-source tool for investigating these structures. It consists of 3D-printed modules representing the silica tetrahedra and metal–oxygen octahedra that form the shared chemical building blocks of rock-forming minerals. TotBlocks is a low-cost visualization tool that relates mineral properties (habit, cleavage, and symmetry) to crystal structures.

Short summary
Some volcanic eruptions are driven by huge gas pockets called Taylor bubbles. Volcanologists use experiments that replicate flow inside volcanic conduits to study these eruptions. We show for the first time that kymography – an open-access tool that condenses thousands of frames of experiment footage into one measurable image – can be used to quantify key Taylor bubble flow parameters to help us understand the frequency and explosivity level of bubble-driven eruptions, and the gaps in between.

Here we introduce a new approach for analysing time-resolved 3D X-ray images tracking mineral changes in rocks. Using deep learning, we accurately identify and quantify the evolution of mineral components during reactions. The method demonstrates high precision in quantifying a metamorphic reaction, enabling accurate calculation of mineral growth rates and porosity changes. This showcases artificial intelligence's potential to enhance our understanding of Earth science processes.

Short summary
Hydraulic rock properties such as porosity and permeability are relevant factors that have an impact on groundwater resources, geological repositories and fossil fuel reservoirs. We investigate the influence of chemical compaction upon the porosity evolution in salt–biotite mixtures and related transport length scales by conducting laboratory experiments in combination with 4-D analysis. Our observations invite a renewed discussion of the effect of sheet silicates on chemical compaction.

Editorial statement
In curling – one of the 2026 Winter Olympic sports - stones are slid on ice and made to collide along a circumferential striking band. Each stone experiences thousands of impacts per season, over a lifespan of 10–15 years before refurbishment. This provides a unique opportunity to investigate fatigue and damage accumulation under cyclic loading, which is exactly what this unconventional study of rock physics and curling does.

Short summary
Curling stones often collide with each other during a game. Over time, these collisions cause damage in the striking bands on the sides of the stones. We determined experimentally how hard these stones collide into one another. We then looked at old curling stones to understand how damage builds up in these rocks. We found that early, fast impacts produce fractures until the striking band is saturated in fractures. Repeated impacts after this stage make fractures grow.
