“…Although the deregulation of clock genes under RF-EMF conditions could be explained by the sensory role of cry genes, the mechanism by which survivin expression can respond to RF-EMF is completely unknown. A functional E-box was not revealed in the survivin sequence, and survivin mRNA did not show rhythmic expression [ 101 ]. However, previously, survivin expression was shown to have a negative correlation with the clock gene per2 in patients with colorectal cancer [ 102 ]; thus, it is possible that survivin expression is functionally related to the circadian oscillator indirectly, at least in some specific biological context.…”

Radiofrequency electromagnetic fields (RF-EMF) exert pleiotropic effects on biological processes including circadian rhythms. miR-34a is a small non-coding RNA whose expression is modulated by RF-EMF and has the capacity to regulate clock gene expression. However, interference between RF-EMF and miR-34a-mediated regulation of the circadian oscillator has not yet been elucidated. Therefore, the present study was designed to reveal if 24 h exposure to 2.4 GHz RF-EMF influences miR-34a-induced changes in clock gene expression, migration and proliferation in colorectal cancer cell line DLD1. The effect of up- or downregulation of miR-34a on DLD1 cells was evaluated using real-time PCR, the scratch assay test and the MTS test. Administration of miR-34a decreased the expression of per2, bmal1, sirtuin1 and survivin and inhibited proliferation and migration of DLD1 cells. When miR-34a-transfected DLD1 cells were exposed to 2.4 GHz RF-EMF, an increase in cry1 mRNA expression was observed. The inhibitory effect of miR-34a on per2 and survivin was weakened and abolished, respectively. The effect of miR-34a on proliferation and migration was eliminated by RF-EMF exposure. In conclusion, RF-EMF strongly influenced regulation mediated by the tumour suppressor miR-34a on the peripheral circadian oscillator in DLD1 cells.

With the rapid development of the Internet of Things (IoTs), numerous distributed wide‐area low‐power electronic devices have been utilized in various fields, such as wireless monitoring sensors and wearable electronics. Due to the dispersion and mobility of microelectronic devices, their energy supply faces serious challenges. The inconvenience and non‐environmental friendliness of using traditional centralized low entropy energy and chemical batteries to power distributed microelectronic devices are becoming increasingly prominent. Environmental energy harvesting technology with high entropy characteristics is considered an effective solution for low‐power electronic devices. This paper comprehensively reviews the recent progress in microelectronic technologies based on energy harvesting and signal sensing. First, state‐of‐the‐art micro‐power electronic devices in humans, animals, and the environment are introduced. Secondly, the available micro‐energy sources in the environmentare elaborated and summarized. Then, the principles and characteristics of ambient microenergy harvesting technologies based on different mechanisms are classified, summarized, and analyzed. In addition, this work comprehensively summarizes the applications of self‐powered micro‐electronics technology in 11 different fields, including human, animal, and environment. Finally, research challenges, technical difficulties, and research gaps in self‐powered microelectronics based on micro‐energy harvesting technology are discussed and summarized.

“…The fifth paper is led by Jesse Granger, a Ph.D. student in Sönke Johnsen's lab at Duke University, who showed whale strandings are associated with atmospheric RF, presumably due to its impact on whales' ability to navigate (Granger et al 2020). In the special issue, she discusses how to quantify RF, the natural sources of RF and its potential to affect magnetosensitive animals by comparing environmental values to a metaanalysis of behavioral experiments in which RF has been shown to disrupt orientation (Granger et al 2022). The sixth paper comes from another Ph.D. student in the lab of Henrik Mouritsen, Bo Leberecht, who, with a distinguished team including Michael Winklhofer and Peter Hore, examines the disruptive effect of RF with a range of 75-85 MHz on Eurasian blackcaps (Sylvia atricapilla) and provides new information on the possible radical pair associated with magnetic field detection (Leberecht et al 2022).…”
