This PubMed-listed study models and experimentally validates how subcutaneous fat thickness affects temperature distribution during monopolar radiofrequency (RF) treatment used for skin tightening and tissue repair. Using finite element analysis (COMSOL) and in vitro pork tissue experiments, the authors report that thicker fat layers reduce achieved intratissue temperatures under the same RF settings. The paper concludes that RF energy parameters may need adjustment based on adipose thickness to reach desired effects while staying within stated epidermal safety limits.
Human cells response to electromagnetic waves of radio and microwave frequencies
This review discusses how human cells may sense and respond to electromagnetic waves, focusing on radiofrequency and microwave ranges. It reports that the literature shows variable health impacts, with studies citing both potential harms and potential benefits in diagnostics and treatment (including cancer-related applications). The review highlights emerging molecular mechanisms and calls for safe, practical applications and balanced consideration in regulation.
Skin Fibroblasts from Individuals Self-Diagnosed as Electrosensitive Reveal Two Distinct Subsets with Delayed Nucleoshuttling of the ATM Protein in Common
This study reports on 26 adults self-diagnosed with electromagnetic hypersensitivity (EHS) who provided skin biopsies to generate primary fibroblast lines. The authors describe two EHS subsets based on questionnaire and DNA damage-related measures, and report delayed ATM nucleoshuttling after X-ray exposure in all samples, interpreted as impaired DNA repair signaling. They propose a molecular model linking EHS to ATM pathway dysfunction and suggest this could relate to increased cancer risk or accelerated aging.
Earth's magnetic field and its relationship to the origin of life, evolution and planetary habitability
This review synthesizes evidence on Earth's geomagnetic field history and discusses how early establishment of the field (at least 4.2 billion years ago, inferred from zircon magnetism) may have supported planetary habitability via radiation shielding and water preservation. It highlights a proposed near-collapse of the dynamo near the end of the Precambrian and subsequent renewal in the earliest Cambrian, with potential implications for atmospheric escape and oxygenation. The paper frames several links to biological evolution (including Ediacara fauna) as possible and in some cases debated.
