In his work with silkworms, Pasteur developed practices that are still used today for preventing disease in silkworm eggs.

Detailed explanation-4: -Indefatigable despite a career of physically demanding and ultimately fatal work, she discovered polonium and radium, championed the use of radiation in medicine and fundamentally changed our understanding of radioactivity.
