Electromagnetic fields modulate neuronal membrane ionic currents through altered cellular calcium homeostasis

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
Electromagnetic fields (50 Hz, 1 mT) affect hippocampal CA1 neuron excitability by reducing membrane currents. These effects, blocked by agents targeting calcium signaling pathways, suggest EMFs influence neuronal function via disruption of Ca2⁺ homeostasis and voltage‐gated channel regulation. Abstract The biological effects of electromagnetic fields (

Constrained flash sintering of gadolinium‐doped ceria thin layers

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract Flash sintering is a novel technology, which enables densification of ceramics in seconds to minutes at moderate furnace temperatures. To date, it has mostly been demonstrated on samples with simple geometries like dog bones, bars, or cylinders, which are quite far from real applications.

Impact of magnetic fields from tablets, laptops, smartphones, and household/leisure magnets on cardiac implantable electronic devices

open access: yesJournal of Arrhythmia, Volume 41, Issue 4, August 2025.
This study on 13 Cardiac implantable electronic device (CIED) models revealed that surface magnetic fields of tablets, laptops, smartphones, and household magnets exceeded 10 G, potentially triggering magnet response mode. Activation occurred at ≤15 mm for electronic devices and ≤7 mm for household magnets.

Comparative study of radiofrequency heating in deep brain stimulation devices during MRI at 1.5 T and 0.55 T: Challenging the assumption of safety at low field strengths

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 2, Page 785-796, August 2025.
Abstract Purpose Low‐field MRI has been assumed to be implant‐friendly based on limited studies. However, radiofrequency (RF)–induced heating due to an implant is a complex resonance phenomenon, highly dependent on the implant's configurations and applied RF frequencies.
