Dec 17, 2025
RF Safe founder John Coates publishes an open letter urging YouTuber MrBeast (Jimmy Donaldson) to make any potential “Beast Mobile” offering explicitly child-protective and “Li‑Fi compatible,” arguing that phones carried close to the body could scale long-term RF exposure among children. The letter frames current…
The Systematic Review on RF-EMF Exposure and Cancer by Karipidis et al. (2024) has Serious Flaws that Undermine the Validity of the Study's Conclusions

This letter critiques the WHO-sponsored systematic review by Karipidis et al. (2024) on RF-EMF exposure and cancer risk. The authors argue the review has serious methodological and interpretative flaws, including issues with study selection and data analysis. They contend that the review’s conclusion of "no clear…
Construction of solar-wind-like magnetic fields.

Jan 1, 2012
This Letter presents a method for constructing solar-wind-like magnetic fields that are nearly constant in magnitude, divergence-free, and match any specified fluctuation power spectrum. The approach selects relative phases between two polarizations per wave vector to minimize variance in field magnitude while…
Dominant mobility modulation by the electric field effect at the LaAlO3/SrTiO3 interface.

Jan 1, 2009
This Physical Review Letters paper reports magnetotransport measurements on a gated LaAlO3/SrTiO3 interface to assess the main effect of an applied gate electric field. The authors find that mobility changes dominate over sheet carrier density changes (mobility variation reported as nearly fivefold larger). They also…

Jan 1, 2007
This Physical Review Letters paper reports a method to reverse electric polarization in multiferroic TbMnO3 using a rotating magnetic-field direction, without applying an electric field or heat. The authors state that the direction of magnetic-field-induced polarization along the a axis is retained as a memory even…
Magnetic field switching between the two orbital-ordered states in DyVO3.

Jan 1, 2007
This Physical Review Letters study investigates phase competition between spin- and orbital-ordered states in a DyVO3 single crystal. The abstract reports reentrant temperature-driven transitions in spin ordering and orbital ordering. It also reports that an applied magnetic field can switch between orbital-ordered…
