Power-frequency magnetic field exposure at 100 μT does not appear to cause DNA damage in cardiomyocytes based on this study's findings.
Plain English Summary
Summary written for general audiences
This study investigated whether exposure to 50 Hz magnetic fields at 100 μT induces DNA damage in cardiomyocytes using both in vitro human cell cultures and in vivo rat models. The results showed that ELF-MF exposure did not induce DNA damage, alter cell cycle distribution, increase reactive oxygen species, or significantly change p53 and Hsp70 protein expression levels.

}Quick Questions About This Study
The study found rural BMI increased at the same rate or faster than urban areas in low- and middle-income regions, likely due to changing food systems, reduced physical activity, and modernization reaching rural communities over the 32-year study period.
Low- and middle-income regions showed the most dramatic rural BMI increases, with more than 80% of BMI rise in some areas attributed to rural populations rather than urban dwellers, particularly affecting women.
More than 55% of the global rise in mean BMI from 1985 to 2017 was due to increases in rural areas, not cities, based on data from over 112 million adults across 2,009 population studies.
Yes, the BMI gap between urban and rural areas closed significantly in low- and middle-income countries from 1985 to 2017, with some countries showing complete reversal where rural BMI now exceeds urban BMI, especially for women.
High-income and industrialized countries showed persistently higher rural BMI throughout the study period, especially for women, suggesting different patterns of obesity development compared to developing nations where rural areas caught up to cities.
