<div><div>Surfactants are molecules capable of positioning themselves at the interface between two immiscible media, such as the water/air interface or the water/oil interface, and of acting on the molecular interactions between these two media. Chemically, these active molecules have two parts: a hydrophilic part, soluble in water, and a hydrophobic part, often made up of hydrocarbon or fluorocarbon chains, which interact with nonpolar substances such as fats or oils. This amphiphilic character allows them to accumulate at the interface between two immiscible media. This positioning, combined with their physicochemical properties, is the origin of their action on surface or interfacial tension. The effect of the surfactant results in a reduction of this tension, i.e., the energy required to maintain the interface, thus altering the molecular interactions between the two phases. In the absence of surfactants, the interfacial tension between two immiscible phases is high due to cohesive forces within each medium and weak interactions between molecules of one phase and those of the other phase. The high interfacial tension results in the formation of distinct layers, each corresponding to one of the phases. For example, to minimize the contact surface between oil and water, a drop of oil remains spherical when added to an aqueous solution. When the volume of the oil phase is increased, droplets tend to coalesce in order to quickly minimize the interfacial energy. In the presence of surfactants accumulating between the two phases, the interaction forces within each phase are disturbed, and the interfacial tension is reduced. The oil droplets dispersed in an aqueous phase are less likely to regroup, thus reducing phase separation. The addition of surfactants to a solution can thus enable the dispersion of one phase into another liquid phase (emulsion), or even the stabilization of solid particles in suspension. Surfactants are classified into four main families, depending on whether or not they carry a charge on their hydrophilic part, and based on the nature of this charge: anionic, cationic, nonionic, or zwitterionic surfactants. Each of these families finds numerous applications in our daily lives. It is worth noting that, alongside the classic surfactants described above, some complex molecules, such as proteins, are also used in industry for their surfactant properties. Surfactants are mainly used for their solubilizing, phase-stabilizing, emulsifying, or foaming properties. Below a certain concentration, called the critical micelle concentration (CMC), surfactants are mainly in monomolecular form. Beyond the CMC, they form micelles. In aqueous solution, these self-assembled structures correspond to molecular organizations in which the hydrophobic parts gather at the center to limit their contact with the polar solvent, while the hydrophilic parts are exposed to the outside of the structure and interact with water. Thus, surfactant micelles find

The unintentional introuction of the ragweed leaf beetle (Ophraella communa) in France marks a significant step in the biological management of common ragweed (Ambrosia artemisiifolia), an invasive plant with major health impacts. Originally from North America, like ragweed itself, this beetle has recently naturalized in several regions of Europe, before being observed for the first time in France in 2023. Scientists are tracking the population dynamics of O. communa, examining its dispersal mechanisms, and assessing its potential as a natural biocontrol agent against ragweed. While promising, this introduction raises questions about the ecological impact of the exotic beetle in this new ecosystem.

In response to climate change and new dietary trends, the sustainable production of novel protein sources, as alternative to those of animal origin, and the use of novel food ingredients and complements are increasing. In this context, the allergenic risk of these novel foods needs to be assessed. Current guidance for allergenicity risk assessment relies on a weight-of-evidence approach to determine the risk of de novo sensitization and the risk of cross-reactivity to novel food antigens in patients already sensitized to known allergens. Nevertheless, the evolution of our dietary habits will inevitably increase the frequency of certain food allergies, as already observed for insect or legume proteins. Therefore, alongside the development of in silico and in vitro experimental models to better apprehend the allergenic potential of foods, anaphylaxis registries remain a critical tool for monitoring and warning of emerging allergens.
