No observable non-thermal effect of microwave radiation on the growth of microtubules

Abstract

Overview

Despite widespread public interest in the health impact of exposure to microwave radiation, studies often present inconclusive or contradictory results.

Findings

This research specifically investigated the influence of microwave radiation, at frequencies of 3.5 GHz, 20 GHz, and 29 GHz, on the growth of microtubules—biological nanotubes crucial for various cellular functions. It was hypothesized that microtubules, being polar and elongated, might be particularly sensitive to non-ionizing radiation.

• Study suggested tubulin dimers might react to radiation, indicating possible non-thermal interactions.
• Experiments conducted included control groups using infrared lasers and hot air to simulate thermal effects. These controls reproduced the distorted growth curves seen in radiated samples.

Conclusion

No specific non-thermal effects of microwave radiation were observed on microtubule growth, indicating that previous distortions in growth may be attributable to standard thermal effects rather than radiation specifically. Highlights the necessity of adequate controls in biophysical experiments impacting public interest areas.
