Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review
BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope
Integrative Zoology, EarlyView.The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.
