Plate Tectonics and Metamorphism: Teaching Complex Systems Using Videos and Animations

Geosciences
Metamorphism is a complex geologic process that is often poorly covered in introductory geology courses. This study explores the effectiveness of a video-based instructional intervention in improving student understanding of metamorphism and its ...

Metasomatites of medium and mafic composition from Nyaschevo massif (Ilmeny Mauntains, South Urals)

Литосфера, 2015
The results of the study of mediosiliceous and mafic metasomatites located in ultramafic and mafic rocks Nyaschevo massif presents in the paper. The texthural and structural features of these rocks allow to attribute them to tectonites - protomylonites and

The Earth's Greatest Porous Media

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ15N Integrity of Nitrogen‐Poor Samples

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Long‐Term Population Declines of Habitat‐Shifting Species in the City: A Living Planet Index Approach for Berlin, Germany

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We applied two global biodiversity indices at a city scale and revealed significant declines in odonate and amphibian populations in freshwater systems over several decades. Our study demonstrates the effectiveness of both indices as a baseline for fulfil urban‐related biodiversity framework targets if suitable biodiversity time series are available ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

The selective degradation of PDE4B shortform, using a PROTAC, leads to inhibition of several hallmarks of cancer in HCT116 cells

British Journal of Pharmacology, Volume 183, Issue 18, Page 5516-5540, September 2026.
Background and Purpose Colorectal cancer is one of the most prevalent cancers worldwide, and novel precision medicine approaches are rapidly improving patient outcomes. Phosphodiesterase 4B (PDE4B) is a member of an enzyme family (PDE4) that hydrolyses intracellular cAMP to control spatial and temporal signalling cues.
