Researchers at the Weizmann Institute of Science have created an artificial "embryo model" that mimics a 14-day-old human embryo without using sperm, eggs, or a womb. They achieved this by starting with pluripotent stem cells, which can develop into various tissue types, and coaxing them into becoming four cell types found in early human embryos. Think of it like making a cake with cells instead of flour and sugar. By mixing these cells in specific ratios, they created an artificial embryo without harming any eggs.
