Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.

Report on lunar ranging at McDonald Observatory for the period February 16 to April 15, 1970 [PDF]
, 1970 This report describes the lunar ranging activities at McDonald Observatory and the associated activities at the University of Maryland for the two-month period February 16, 1970 to April 15, 1970. During this period numerous acquisitions were obtained. A

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.Field campaigns establish a novel hydro‐eco‐geomorphic database for St. Lawrence Estuary saltmarshes; foundations to predict ecosystem evolution in an understudied region. Documented spatial and temporal variability in vegetation traits, inundation dynamics and sediment supply warrants further investigation in saltmarsh modelling frameworks.

Testing Fifth Forces from the Galactic Dark Matter
Proceedings, 2019 Is there an unknown long-range force between dark matter (DM) and ordinary matters? When such a fifth force exists and in the case that it is ignored, the equivalence principle (EP) is violated apparently. The violation of EP was severely constrained by,

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp
Small, Volume 22, Issue 54, 25 September 2026.Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.
