Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve ...
Who hasn't seen it before: the view through the microscope in which a sperm penetrates an egg cell and fertilizes it. This fundamental step in procreation happens dynamically and seemingly without ...
New research challenges the idea that self-fertilization is an evolutionary dead end and points to a more complex story.
