Assessing the Reliability of the Pseudo‐Thellier Estimates in Fired Ceramics and Source Clays

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The geomagnetic field's intensity is key to understanding the Earth's core dynamics and their surface impacts. While the Thellier–Thellier method remains the standard for recovering absolute paleointensity from baked materials, it is time‐consuming and may alter magnetic mineralogy due to heating cycles. The pseudo‐Thellier method offers a non‐

Mixing of Two Microbial Consortia in the Search for Stimulating Chromium Depletion

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Two bacterial consortia (C55 and C33), obtained from an industrial residue contaminated with hexavalent chromium (Cr(VI)), were used to study the behavior of their mixture for depleting this ion in liquid media. In the absence of Cr(VI), C55 showed a greater growth rate than C33, while the latter exhibited biofilm formation. In the presence of this ion,

Vortex Nanodiscs Functionalization to Overcome Macrophage Recognition for Efficient Theragnosis Applications

Advanced Engineering Materials, Volume 26, Issue 24, December 2024.
Biological barriers prevent nanotherapeutics successful accumulation at target cells, limiting diagnosis and treatment responses. The surface of magnetic nanodiscs in a spin‐vortex ground state is modified with polyethylene glycol (PEG) molecules, which allow a reduction of the macrophage's uptake, while maintaining the nanodiscs’ biocompatibility.

Descartes on Place and Motion: A Reading through Cartesian Commentaries**

Berichte zur Wissenschaftsgeschichte, Volume 47, Issue 3, Page 179-214, September 2024.
Abstract This paper offers a reconstruction of the interpretations of Descartes's ideas of place and motion by Dutch Cartesians (Henricus Regius, Johannes de Raey, Johannes Clauberg, and Christoph Wittich). It does so by focusing on the reading of Descartes's Principia philosophiae (1644) offered, in particular, by the dictated commentaries on it.

Developing, Testing, and Communicating Earthquake Forecasts: Current Practices and Future Directions

Reviews of Geophysics, Volume 62, Issue 3, September 2024.
Abstract While deterministically predicting the time and location of earthquakes remains impossible, earthquake forecasting models can provide estimates of the probabilities of earthquakes occurring within some region over time. To enable informed decision‐making of civil protection, governmental agencies, or the public, Operational Earthquake ...

Labile assembly of a tardigrade protein induces biostasis

Protein Science, Volume 33, Issue 4, April 2024.
Abstract Tardigrades are microscopic animals that survive desiccation by inducing biostasis. To survive drying tardigrades rely on intrinsically disordered CAHS proteins, which also function to prevent perturbations induced by drying in vitro and in heterologous systems.
