Crystallization-induced stress within confined spaces of porous materials presents significant challenges across various disciplines, including conservation science, geomorphology, geotechnical engineering, and concrete durability. Despite its significance, understanding how localized, transient, and anisotropic stress is generated in pores due to...

Sperm rheotaxis, the phenomenon where sperm cells swim against the direction of fluid flow, is one of the major guiding mechanisms for long-distance sperm migration within the female reproductive tract. However, current approaches to study this pose challenges in dealing with rare samples by continuously introducing extra buffer. Here, we developed...

Sperm motility is a significant predictor of male fertility potential and is directly linked to fertilization success in both natural and some forms of assisted reproduction. Sperm motility can be impaired by both genetic and environmental factors, with asthenozoospermia being a common clinical presentation. Moreover, in the setting of assisted rep...

Male infertility is a global reproductive issue, several clinical approaches have been developed to tackle it, but their effectiveness is limited by the labour-intensive and time-consuming sperm selection procedures used. Here, we present an automated, acoustic based continuous-flow method capable of selecting high quality sperm with considerably i...
