A Novel Soil Chronometer: Uranium Comminution Ages Measure Soil Production Rates in a Deep Granitic Weathering Profile

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

The DNA of Calabi–Yau Hypersurfaces

Fortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Building Connections to Teach the Nature of Science: An Experienced Science Teacher's Formative Assessment Practices in a High School Classroom

Journal of Research in Science Teaching, Volume 63, Issue 2, Page 161-185, February 2026.
ABSTRACT While understanding the nature of science (NOS) is recognized as a key component of science education because of its potential benefits in nurturing scientific literacy, there is currently limited knowledge on how NOS learning can be supported by teachers' ongoing, in‐the‐moment assessment in the classroom.

Tectonics as a Regulator of Shoreline Retreat and Rocky Coast Evolution Across Timescales

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Rocky coast morphology is shaped by interactions between wave action, sea level, and tectonics over millennial time scales. However, a clear and quantifiable signature of tectonic uplift on decadal to centennial shoreline retreat rates is outstanding.
