UMR-MARBEC, Université de Montpellier, CNRS, Ifremer, IRD, Place Eugène Bataillon, Montpellier 34095, France; Australian Rivers Institute, Griffith University, Gold Coast, 4215 Queensland, Australia. Electronic address:

The effects that anthropogenic stressors may have on modulating species' plasticity has been relatively unexplored; however, it represents a scientific frontier that may offer insights into their ability to colonize new habitats. To explore the advantage that inhabiting polluted environments may offer to invasive species, we selected the crayfish Procambarus clarkii, a species that can colonize and thrive in a wide range of aquatic environments, including heavily polluted ones. Here, we studied the molecular and physiological responses of crayfish when experimentally exposed to a pesticide mix of azoxystrobin and oxadiazon at sublethal concentrations.

January 2025

Centre d'Etudes Biologiques de Chizé, UMR7372 CNRS-La Rochelle Université, Villiers en Bois, France.

Early life telomere length is thought to influence and predict an individual's fitness. It has been shown to vary significantly in early life compared to adulthood. Investigating the factors influencing telomere length in young individuals is therefore of particular interest, especially as the relative importance of heredity compared to post-natal conditions remains largely uncertain.

P2 purinergic receptors at the heart of pathological left ventricular remodeling following acute myocardial infarction.

Am J Physiol Heart Circ Physiol

January 2025

Université de Tours, Inserm UMR1327 ISCHEMIA Membrane Signalling and Inflammation in reperfusion injuries, Tours, France.

Pathological left ventricular remodeling is a complex process following an acute myocardial infarction, leading to architectural disorganization of the cardiac tissue. This phenomenon is characterized by sterile inflammation and the exaggerated development of fibrotic tissue, which is non-contractile and poorly conductive, responsible for organ dysfunction and heart failure. At present, specific therapies are lacking for both prevention and treatment of this condition, and no biomarkers are currently validated to identify at-risk patients.

Université de Lyon, CREATIS ; CNRS UMR5220 ; Inserm U1206 ; INSA-Lyon ; Université Lyon 1, CREATIS, Centre Léon Bérard, Lyon, 69373, FRANCE.

Rigid patient motion can cause artifacts in single photon emission computed tomography (SPECT) images, compromising the diagnosis and treatment planning. Exponential data consistency conditions (eDCCs) are mathematical equations describing the redundancy of exponential SPECT measurements. It has been recently shown that eDCCs can be used to detect patient motion in SPECT projections.

Background: The increasing availability of electronic health system data and remotely-sensed environmental variables has led to the emergence of statistical models capable of producing malaria forecasts. Many of these models have been operationalized into malaria early warning systems (MEWSs), which provide predictions of malaria dynamics several months in advance at national and regional levels. However, MEWSs rarely produce predictions at the village-level, the operational scale of community health systems and the first point of contact for the majority of rural populations in malaria-endemic countries.

Background: Upland cotton (Gossypium hirsutum) plants constitutively store volatile terpenes in their leaves, which are steadily emitted at low levels. Herbivory leads to a greater release of these stored volatiles. Additionally, damaged plants increase the accumulation of volatile terpenes in their leaves and begin to synthesize and emit other terpenes and additional compounds.

Mass controls two major processes in volcanic islands: large-scale collapse and vertical movements. Therefore, large islands like Hawaii are gradually subsiding and have undergone massive landsliding. What if the mass is much smaller, and there is good evidence that the vertical movement is more complex than simple loading-related subsidence? Here, we show that small volcanic islands, seemingly stable because of the small mass, can undergo sector collapses that can affect the vertical movement of the island.

This study reports the preparation of cellulose nanocrystals (CNCs) from commercial bleached eucalyptus Kraft pulp (BEKP) using a hydrothermal treatment in the presence of maleic acid (MA), followed by high-pressure homogenization. Compared with conventional hydrolysis methods, this approach offers significant advantages, including lower acid concentration, higher yield, and milder processing conditions. CNCs were produced with a high yield (70-85 wt %) by high-pressure homogenization of hydrothermally treated BEKP fibers with 10-20 wt % maleic acid at 150 °C, giving rise to a stable translucent gel of CNCs with a rod-like morphology (200-400 nm length and 10-40 nm width).

Probing spin-electric transitions in a molecular exchange qubit.

Nat Commun

January 2025

Institut de Chimie de Strasbourg (UMR 7177, CNRS-Unistra), Université de Strasbourg, 4 rue Blaise Pascal, CS 90032, F-, Strasbourg, France.

Electric fields represent an ideal means for controlling spins at the nanoscale and, more specifically, for manipulating protected degrees of freedom in multispin systems. Here we perform low-temperature magnetic far-IR spectroscopy on a molecular spin triangle (Fe) and provide initial experimental evidence suggesting spin-electric transitions in polynuclear complexes. The co-presence of electric- and magnetic-dipole transitions, allows us to estimate the spin-electric coupling.

Cell adhesion and spreading on fluid membranes through microtubules-dependent mechanotransduction.

Nat Commun

January 2025

Institut Curie, Université PSL, Sorbonne Université, CNRS UMR168, Laboratoire Physico-Chimie Curie, 75005, Paris, France.

Integrin clusters facilitate mechanical force transmission (mechanotransduction) and regulate biochemical signaling during cell adhesion. However, most studies have focused on rigid substrates. On fluid substrates like supported lipid bilayers (SLBs), integrin ligands are mobile, and adhesive complexes are traditionally thought unable to anchor for cell spreading.
