Low Sperm Motility Is Determined by Abnormal Protein Modification during Epididymal Maturation

The World Journal of Men's Health, 2022
Purpose:Purpose: During epididymal sperm maturation, spermatozoa acquire progressive motility through dynamic protein modifica-tions. However, the relationship between sequential protein modifications during epididymal sperm maturation and sperm motility

Amphibious Movement of Microrobots Inspired by Water Spiders

Advanced Science, EarlyView.
Inspired by the water strider, a novel microrobot is designed to maintain amphibious mobility in complex environments. It retains the ability to traverse the air‐liquid interface and perform directional movement within sophisticated, multifaceted environments, including complex gastric wall structures, with precise controllability.
