A model using the rigid body multi-cellular framework (RBMCF) is implemented to investigate the mechanisms of buckling of an epithelial monolayer. Specifically, the deformation of a monolayer of epithelial cells which are attached to a basement membrane and the surrounding stromal tissue. The epithelial monolayer , supporting basement membrane and stromal tissue are modelled using two separate vertex dynamics models (one for the epithelial monolayer layer and one for the basement membrane and stromal tissue combined) and interactions between the two are considered using the RBMCF to ensure biologically realistic interactions.

Design: Eighteen handball players (naturally menstruating: n = 8) completed performance test batteries on three separate occasions.
Methods: The performance test battery included: a 1-repetition Smith machine back squat, maximal handgrip strength tests, counter-movement jumps, squat jumps, a modified agility T-test, and 15-m linear sprints.
Article Synopsis
- This study explored how menstrual cycle phases affect symptom severity and recovery in female athletes, comparing those on different hormonal contraceptives to non-users.
- It found that symptom severity was higher during bleeding days, with hormonal contraceptive users generally reporting milder symptoms, particularly implant users.
- Additionally, pre-bleeding phases correlated with lower sleep quality and readiness to train, emphasizing the need for personalized recovery strategies based on individual symptoms throughout the menstrual cycle.
A novel, robust, and portable platform for magnetoencephalography using optically-pumped magnetometers.

Magnetoencephalography (MEG) measures brain function via assessment of magnetic fields generated by neural currents. Conventional MEG uses superconducting sensors, which place significant limitations on performance, practicality, and deployment; however, the field has been revolutionised in recent years by the introduction of optically-pumped magnetometers (OPMs). OPMs enable measurement of the MEG signal without cryogenics, and consequently the conception of "OPM-MEG" systems which ostensibly allow increased sensitivity and resolution, lifespan compliance, free subject movement, and lower cost.
