This desk is for science questions across the natural sciences and engineering. It covers biology, chemistry, physics, earth sciences, and the applied sciences.

A note on medical questions: editors at the reference desk cannot give medical advice. Questions about symptoms, diagnoses, or treatments should be directed to a qualified healthcare professional. General questions about how the body works, or about the science behind a medical topic, are welcome — but any answer given here is general information, not advice, and must not be treated as a substitute for professional care.
