Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

From Amino Acids to α‐Keto Acids via β‐Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks

open access: yesAngewandte Chemie International Edition, EarlyView.
A reaction starting from two amino acids, phosphoserine and Gly, reveals a pathway to the α‐keto acid building blocks pyruvate and glyoxylate, key components of a plausible early metabolic system. A one‐pot β‐elimination and transamination sequence also initiates a cascade of protometabolic transformations that provide crucial insights into the ...

Contactless Conductivity Detection for Capillary Electrophoresis—Developments From 2020 to 2024

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The review covering the development of capillary electrophoresis with capacitively coupled contactless conductivity detection from 2020 to 2024 is the latest in a series going back to 2004. The article considers applications employing conventional capillaries and planar lab‐on‐chip devices as well as fundamental and technical developments of ...

Space Economy and Sustainability: A Systematic Review

open access: yesSustainable Development, EarlyView.
ABSTRACT The space economy is booming thanks to the increasing investment of government agencies, private companies, and venture capitalists. From the beginning of the New Space era, the array of actors involved in the development of technologies for extra‐terrestrial activities has increased, as well as the downstream applications that foster ...

Investigating Impacts of Amino Acids on the Structural Stability of Anionic Biomembranes

open access: yesChemSystemsChem, Volume 7, Issue 2, March 2025.
Glycine and lysine interact with the anionic membrane composed of POPC and POPG (1 : 1). Lysine partitions into the membrane and induces structural alterations, while the membrane remains impermeable to it. In contrast, glycine causes no physicochemical damage and permeates through the membrane.

Chasing (macro)elements in microinvertebrates: A new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle‐Induced X‐Ray Emission) applied to glacier tardigrades

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample size hindering the application of established methodological approaches.

The evolution of reproduction in Ediacaran–Cambrian metazoans

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 2, Page 245-258, April/June 2025.
ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.

Natural H2 and Sulfate Production via Radiolysis in Low Porosity and Permeability Crystalline Rocks

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 6, June 2025.
Abstract Natural hydrogen (H2) is a candidate low‐carbon energy source for society and sustains microbial ecosystems when coupled with oxidants (e.g., sulfate). In crystalline rock settings, water‐rock interactions, including radiolysis, generate both H2 and sulfate, but quantifying their production rates remains challenging when porosity and ...
