Abstract

Overview

The study focuses on analyzing how varying magnetic environments can impact cardiovascular functioning, specifically through the lens of hypomagnetic fields on zebrafish embryos.

Findings

• Studied the effects of geomagnetic and hypomagnetic fields on zebrafish embryos using a non-invasive optical method.
• Exposure to hypomagnetic fields increased mortality rates, the frequency of abnormal phenotypes, and the heartbeat rate of the embryos.
• Detailed observations were made on the changes in heart rate variability and the rhythm patterns, especially under constant illumination.

Conclusion

The research indicates that natural magnetic backgrounds play a crucial role in the developmental stages of zebrafish embryos. The alterations caused by hypomagnetic fields could imply significant developmental risks, suggesting a deeper underlying biological interaction with Earth's natural magnetic fields.
