Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Staphylococcaceae are a diverse bacterial family with important implications for human and animal health. This study highlights the One Health relevance of their environmental dispersal, particularly, by identifying closely related or genetically identical strains circulating between farm and community environments. Environmental Staphylococcaceae strains were isolated from animal farms and interconnected areas within a university setting, both influenced by anthropogenic activities.

The bone tissue is a specialised connective tissue composed of several components that undergo constant remodelling. The balance between bone deposition and resorption is essential for maintaining a healthy bone structure. In case of a disruption in this remodelling process, which can lead to an imbalance between bone deposition and resorption, an increase in the opacity of a vertebral body may be observed in imaging studies, resulting in what is known as the "ivory vertebra sign".

The great diversity of specialist plant-feeding insects suggests that host plant shifts may initiate speciation, even without geographic barriers. Pheromones and kairomones mediate sexual communication and host choice, and the response to these behaviour-modifying chemicals is under sexual and natural selection, respectively. The concept that the interaction of mate signals and habitat cues facilitates reproductive isolation and ecological speciation is well established, while the traits and the underlying sensory mechanisms remain unknown.

Manatees are semi-social animals, with the mother-calf relationship being considered long-lasting for the species. However, some events lead to the separation of this pair. Orphaned manatee calves can be adopted by other females of the same species.
