De Borre E, De Massia C, Boone MN, Müller P, Thielens A · 2025

Researchers exposed Aedes aegypti mosquito larvae to 5G signals at 3.6 GHz for five days and observed developmental effects. At field strength of 46.2 V/m, larvae developed more slowly, particularly those with poor nutrition. At higher exposure (182.6 V/m), thermal heating altered both development timing and adult mosquito size.

Sensation of electric fields in the Drosophila melanogaster larva

Unknown authors · 2025

Scientists discovered that fruit fly larvae can sense electric fields and actively move toward the negative electrode when exposed to controlled electrical environments. The study identified specific neurons in the larva's head that detect both the strength and direction of electric fields. This finding reveals a previously unknown sensory ability in invertebrates that could help explain how insects navigate and communicate.

This suggests 5G radiation may fundamentally alter how living organisms process energy and nutrients.

Importance of magnetic information for neuronal plasticity in desert ants

Unknown authors · 2024

Scientists studied how desert ants use Earth's magnetic field for navigation by manipulating magnetic conditions and examining brain changes. They found that magnetic information is processed in two key brain regions: the central complex (internal compass) and mushroom bodies (learning and memory centers). This reveals that ants use magnetic fields both for navigation and to calibrate their visual compass systems.

Mutagenic Effect during Combined Exposure to Ionizing and Non-Ionizing Electromagnetic Radiation

Unknown authors · 2024

Russian researchers exposed fruit flies to both gamma radiation and pulsed magnetic fields to study combined effects on genetic damage. They found that the magnetic field exposure actually reduced the genetic damage caused by gamma radiation, creating an unexpected protective effect. The timing of exposure mattered significantly - magnetic fields before radiation provided stronger protection than the reverse sequence.

Mutagenic Effect during Combined Exposure to Ionizing and Non-Ionizing Electromagnetic Radiation

Unknown authors · 2024

Russian researchers exposed fruit flies to both gamma radiation and pulsed magnetic fields to study combined effects on genetic damage. They found that the order of exposure matters - magnetic fields followed by gamma radiation showed protective effects, while the reverse sequence sometimes increased genetic damage. This reveals that different types of electromagnetic radiation can interact in complex ways within biological systems.

Changes in honey bee nutrition after exposure to radiofrequency electromagnetic field

Unknown authors · 2024

Researchers exposed honey bees to radiofrequency electromagnetic fields at three different intensities (12, 28, and 61 V/m) for varying durations and analyzed their blood chemistry. They found that EMF exposure significantly altered key nutritional markers including proteins, glucose, and triglycerides in the bees' hemolymph (blood). The study suggests that RF fields disrupt honey bee nutrition, which could have long-term health consequences for these critical pollinators.

Electromagnetic field exposure affects the calling song, phonotaxis, and level of biogenic amines in crickets

Unknown authors · 2023

Researchers exposed male crickets to power line frequency electromagnetic fields (50 Hz, 7 mT) and found it changed their mating songs and brain chemistry. The EMF exposure increased stress hormones in the crickets' brains by 25-65% and altered their calling patterns, making them more attractive to young females. This suggests EMF acts as a biological stressor that could disrupt natural mating behaviors in insects.

A role of cryptochrome for magnetic field-dependent improvement of sleep quality, lifespan, and motor function in Drosophila

Unknown authors · 2023

Researchers exposed fruit flies to weak magnetic fields (0.4-0.6 mT) and found improved lifespan, sleep quality, and motor function. These benefits only occurred in flies with functioning cryptochrome proteins, which detect magnetic fields through blue light pathways. The study suggests magnetic field exposure can have positive biological effects when the right cellular machinery is present.

No evidence for magnetic field effects on the behaviour of Drosophila

Unknown authors · 2023

Researchers tested whether fruit flies can detect magnetic fields by observing nearly 110,000 flies in carefully controlled experiments. Despite previous studies claiming flies have magnetic sensing abilities, this large-scale investigation found no evidence that Drosophila respond to magnetic fields. The findings suggest earlier positive results were likely statistical errors.

Unknown authors · 2020

Researchers tested how honey bees respond to small changes in magnetic field strength during foraging activities. While bees could detect and initially use magnetic field variations as navigation cues, they consistently preferred food sources with weaker magnetic fields when given a choice. The study shows that magnetic field sensitivity exists in bees but ranks lower than other environmental factors in their decision-making.

German researchers exposed honey bee queen larvae to 900 MHz mobile phone radiation (the same frequency used by GSM cell phones) for 14 days during their development. They found that cell phone radiation significantly reduced the hatching rate of queen bees, though those that did survive showed normal mating success and colony development. This study provides evidence that everyday mobile phone radiation can disrupt critical developmental stages in pollinators.
