    "summary": "This animal study examined whether long-term 2.4 GHz Wi-Fi radiofrequency exposure affects brain miRNA expression and fatty acid composition. Sixteen rats were assigned to sham or exposure, with the exposure group receiving 24 h/day Wi-Fi radiation for one year. The study reports increases in rno-miR-181a-5p, phosphatidylserine, and triacylglycerol in the brain after exposure, and the authors suggest such changes could be relevant to disease risk.",
