Future Biotechnology on Instagram: "When a sperm successfully fertilizes an egg, a rapid release of zinc ions occurs from the surface of the oocyte. This event is known as the zinc spark. It was first observed in mammalian eggs using advanced imaging techniques, where the zinc ions produce a burst of fluorescence that looks like a spark of light. These sparks are not just visually striking—they are biologically significant. The release of zinc plays a critical role in oocyte activation, a proces

BIOLOGY | MEDICAL | HEALTH on Instagram: "This video offers a captivating look at the major stages of human embryonic development—from fertilization to initial organ formation. It begins with a single-celled zygote and follows its journey through rapid cell divisions, implantation in the uterine wall, and the formation of the blastocyst. As development progresses, the animation highlights biological milestones such as gastrulation, germ layer formation, cell differentiation, and the emergence of
