In most murine species, spermatozoa exhibit a falciform apical hook at the head end. The function of the sperm hook is not yet clearly understood. In this study, we investigate the role of the sperm hook in the migration of spermatozoa through the female reproductive tract in (C57BL/6), using a deep tissue imaging custom-built two-photon microscope.

- A new optical tactile sensor using upconversion nanocrystals can separate dynamic touch signals into vertical normal and lateral shear forces from a single image in real-time.
- This sensor mimics the way human skin works, providing a unique luminescence signal that differentiates between static and dynamic forces.
- It offers high accuracy in identifying small objects and can recognize fingerprints, leading to innovative applications like Braille-to-Speech translation and advanced handwriting recognition systems.
In nature, bacteria often swim in complex fluids, but our understanding of the interactions between bacteria and complex surroundings is still evolving. In this work, rod-like swims in a quasi-2D environment with aqueous liquid-liquid interfaces, , the isotropic-nematic coexistence phase of an aqueous chromonic liquid crystal. Focusing on the bacteria motion near and at the liquid-liquid interfaces, we collect and quantify bacterial trajectories ranging across the isotropic to the nematic phase.
