Fine Characterization of the Contact Zones of Mazzaella laminarioides in the Southeastern Pacific Using Mitochondrial and Nuclear Markers

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates the genetic structure of Mazzaella laminarioides, an ecologically and economically important species from the rocky coast of Chile. Using more accurate sampling and a set of microsatellite, nuclear, and mitochondrial markers, we were able to identify with high resolution the contact zones between the previously described ...

Glacial meltwater drives high CH4 supersaturation in Maxwell Bay, King George Island (Southern Ocean)

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 867-876, December 2025.
Abstract Coastal waters exhibit the highest and most dynamic dissolved CH4 concentrations in marine environments, but significant knowledge gaps on the distribution and emissions, particularly in the Southern Ocean, still exist. We quantified dissolved CH4 concentrations and sea–air fluxes in the coastal waters of Maxwell Bay, King George Island ...

Machine Learning for Maximizing the Memristivity of Single and Coupled Quantum Memristors

Advanced Quantum Technologies, Volume 8, Issue 12, December 2025.
Machine learning (ML) methods are proposed to characterize the memristive properties of single and coupled quantum memristors. It is shown that maximizing the memristivity leads to large values in the degree of entanglement of two quantum memristors, unveiling the close relationship between quantum correlations and memory.

The Invisible Risks of Extractive Infrastructure Networks and Mining

Visual Anthropology Review, Volume 41, Issue 2, Fall 2025.
Abstract This article uses Actor‐Network Theory to analyze mining infrastructures in Chile and develop a concept of “extractive infrastructure networks.” Focusing on the port of Punta Chungo and its connection to the Los Pelambres mine, we explore how these infrastructures, along with human and non‐human actors, create networks that sustain the ...
