Understanding complex volcanic hydrosystems using a multi-tracer approach.

Sci Total Environ

January 2025

CNRS, SIGMA Clermont, Institut de Chimie de Clermont-Ferrand, Université Clermont Auvergne, F-63000 Clermont-Ferrand, France.

Climate change affects groundwater availability and residence times, necessitating a thorough understanding of aquifer characteristics to define sustainable yields, particularly in regions where water is heavily exploited. This study focuses on the Volvic volcanic aquifer (Chaîne des Puys, France), where groundwater recharge has decreased due to climate change, raising concerns about water use sustainability. To address these challenges, this work proposes a multi-tracer approach, based on hydrogeological monitoring, including the estimation of groundwater ages, major elements chemistry and water stable isotopes to better characterise this resource decrease and more peculiarly its origin and its impact on the environment that has never been addressed.

Service de Thérapie Cellulaire et d'Hématologie Clinique, CHU Estaing, Clermont-Ferrand, France.

The advent of BTK inhibitors has been transformative in the management of patients with chronic lymphocytic leukemia or other B-cell lymphoproliferative disorders. However, emergence of BTK or PLCG2 mutations lead to resistance to these compounds and are now a growing concern in clinical practice. Assessing BTK mutations is now becoming a priority to guide the therapeutic decision at further relapse.

This paper investigates how climate policy uncertainty (CPU) drives the sensitivity of Gulf Cooperation Council (GCC) countries' stock markets to oil price changes. Based on a sample of monthly observations from 2008 to 2022, it appears that CPU negatively moderates the link between lagged oil price changes and subsequent GCC stock market returns. Interestingly, the impact of CPU on the oil-stock relationship is non-linear.

Genomic imprinting is the parent-of-origin dependent monoallelic expression of genes often associated with regions of germline-derived DNA methylation that are maintained as differentially methylated regions (gDMRs) in somatic tissues. This form of epigenetic regulation is highly conserved in mammals and is thought to have co-evolved with placentation. Tissue-specific gDMRs have been identified in human placenta, suggesting that species-specific imprinting dependent on unorthodox epigenetic establishment or maintenance may be more widespread than previously anticipated.

People worldwide tend to believe that their societies are more meritocratic than they actually are. We propose the belief in meritocracy is widespread because it is rooted in simple, seemingly obvious causal-explanatory intuitions. Our proposal suggests solutions for debunking the myth of meritocracy and increasing support for equity-oriented policies.

Impact of structural variations and genome partitioning on bread wheat hybrid performance.

Funct Integr Genomics

January 2025

INRAE, Genetics, Diversity and Ecophysiology of Cereals, Université Clermont Auvergne, 63000, Clermont-Ferrand, France.

The agronomical interest of hybrid wheat has long been a matter of debate. Compared to maize where hybrids have been successfully grown for decades, the mixed results obtained in wheat have been attributed at least partially to the lack of heterotic groups. The wheat genome is known to be strongly partitioned and characterized by numerous presence/absence variations and alien introgressions which have not been thoroughly considered in hybrid breeding.
