This randomized controlled crossover trial in 16 male elite soccer players compared two hours of smartphone use before bedtime with magazine reading. Five consecutive nights of pre-bedtime smartphone use significantly worsened multiple sleep metrics and increased sleepiness. The study also reports deteriorations in…

This 30-day daily diary study of 104 first-year undergraduates in China examined links between problematic smartphone use (PSU) and disengagement at within- and between-person levels. The analyses reported bidirectional next-day associations, where higher-than-usual PSU predicted higher-than-usual disengagement and…

This animal study examined whether 50 Hz ELF-EMF exposure at two intensities (1 mT vs 7 mT) alters hippocampal gene transcripts related to neuroplasticity and cell survival in adult rats across repeated exposure cycles. The authors report intensity- and exposure-number-dependent modulation of mRNA expression, with 1…

A laboratory experiment exposed embryos of three benthic egg-laying marine species to realistic electromagnetic fields generated by an alternating-current subsea power cable set-up (magnetic field 4–6 μT). Subtle effects were reported for Scyliorhinus canicula and Loligo vulgaris, including faster growth and…

This engineering/simulation study evaluates tissue SAR from a smartphone operating under single-frequency versus combined (simultaneous 4G and 5G) RF exposure scenarios using multi-pose human models. It reports that peak SAR in various tissues under multi-frequency exposure was 1.02 to 15.85 times higher than under…

This in vitro study reports that 0.1 THz continuous-wave irradiation accelerates DNA base pairing in aqueous environments via a proposed non-thermal mechanism. UV absorption spectroscopy and fluorescence correlation spectroscopy indicated increased G:C base pairing-associated signals and a higher population of…

RF Safe argues that the established term “electromagnetic hypersensitivity” (EHS) should not be replaced by the newer label “EMR Syndrome,” claiming the rebranding fragments research and weakens advocacy. The piece frames EHS as a continuity-based concept tied to reported symptoms in EMF-rich environments and…

RF Safe argues that non-native electromagnetic fields (EMFs) can affect biology through timing and redox mechanisms even without tissue heating, framing this as a challenge to common safety narratives focused on thermal effects. The post links circadian disruption (citing a 2025 Frontiers in Psychiatry paper on ADHD…

RF Safe argues that companies marketing wireless connectivity to children should adopt a precautionary, “ethical connectivity” approach rather than relying on existing U.S. RF exposure rules. The piece claims current FCC guidelines are outdated and cites a 2021 D.C. Circuit decision criticizing the FCC’s retention of…

RF Safe argues that a potential MrBeast-branded mobile service (“Beast Mobile”) could drive high adoption among children and therefore raises ethical concerns about children’s exposure to radiofrequency (RF) emissions from always-on, body-worn devices. The post claims the scientific and legal context has shifted and…

RF Safe argues that modern radiofrequency (RF) exposures are complex (adaptive, nonlinear, geometry- and near-field–dependent) and that biological effects, if any, may be better understood as “timing/coherence” disruptions rather than direct single-cause disease claims. The piece cautions against simplistic “percent…
