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.

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.

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.
