Sources & scientific standards
Clear explanations need clear boundaries around what the evidence supports.
Evidence before excitement
A useful scientific claim identifies the sample, method, measurement, and limitation. A successful experiment in cells or an animal model does not by itself establish a clinical application.
Sources in context
We prioritize original research and authoritative technical or educational sources. References are attached to the pages they inform. Each lesson links to related primary research, with a note about the sample studied. Some frontier topics still have explicit “peer-reviewed source needed” labels; they make no specific claims about unverified formulations or results.
Independent educational content
CryoAtlas is a student-led education project. It has not been presented as a peer-reviewed publication, a clinical service, or a university-endorsed resource. Listed authors and institutions are credited as sources, not as project advisors.
Models and illustrations
The interactive models explain relationships. Their settings are illustrative, not calibrated to a biological sample. They do not provide laboratory protocols or survival predictions. Diagrams simplify structure. Conceptual images are original illustrations created for CryoAtlas using OpenAI ImageGen and credited where they appear; they are not photographs of experiments.
Corrections and ongoing work
Scientific explanations should improve as evidence and review develop. Topics marked as pending need additional primary sources and review.
