An international team of INRAE and CIRAD researchers uncovered over 40,000 remnants of ancient viruses in plant genomes, allowing a unique glimpse into the evolution of plant viruses. Their findings were published in the journal PLoS Pathogens.

Researchers from Japan investigated how microtubules contribute to communication between granulosa cells and oocytes during ovarian follicle development. Focusing on the microtubule-stabilizing protein Camsap3, the team used knockout mouse models and advanced imaging techniques to examine the organization of transzonal projections. Their findings reveal an overlooked role for microtubules in female fertility and provide new insights into the cellular mechanisms that support follicle maturation and successful ovulation.

Researchers at the University of Osaka developed the CLiB assay, a high-throughput platform to engineer protein-based lipid-binding probes. By screening a library of protein variants, they created a highly sensitive probe for the signaling lipid PI(3,5)P₂. This tool allowed the team to visualize how cells remodel their membranes to engulf damaged materials, providing a framework for developing next-generation biosensors and unlocking new insights into the dynamic landscape of biological membranes.

Carpenter ants amputate the injured legs of fellow ants to minimise the risk of infection. A new study involving a Würzburg researcher shows that this task is primarily carried out by ants switching from indoor to outdoor duties.
