SIMPLICA makes big ideas simple. Short, fully animated explainers about science, technology and health: how your body really works, the tech that's changing your life, and what new research actually says.

Every SIMPLICA video is:
• Animated frame by frame, from scratch
• Built on real research, with sources in the description
• Honest about what we know, and what we don't yet

New explainers every week. Tell us in the comments what we should explain next.

Health videos are for education, not medical advice. For anything about your own health, talk to a qualified professional.
