3 postsPersonal radio use and risk of cancers among police officers in Great Britain: Results from the airwave health monitoring study
This prospective cohort analysis from the Airwave Health Monitoring Study evaluated whether occupational personal radio (TETRA) use is associated with cancer risk among 48,457 police officers and staff. Over a median 11 years of follow-up, the study reports no association with all cancers or with head/neck/CNS cancers, and no evidence of a non-linear dose-response with call duration. The authors emphasize that confidence intervals were wide and that a modestly increased risk at high usage cannot be ruled out, supporting continued monitoring.
Role of visual and non-visual opsins in blue light-induced neurodegeneration in Drosophila melanogaster
This animal study used Drosophila knockout lines to examine whether visual (Rh1) versus non-visual (Rh7) opsins contribute to blue-light-associated neural damage. Flies were continuously exposed to 488 nm blue light from egg deposition to 20 days, and brain DNA damage and vacuolisation were assessed. The study reports greater DNA damage and neurodegeneration markers in Rh1 knockout flies than in wild-type or Rh7 knockout flies, and concludes Rh1 is a predominant mediator of blue-light-induced neurotoxicity in the fly CNS.
Extremely Low-Frequency Magnetic Fields (ELF-MF) and Radiofrequency: Risk of Childhood CNS Tumors in a City with Elevated ELF-MF Exposure
This case-control study in Mexico City (2017–2022) evaluated residential ELF-MF and device-use proxies for RF exposure in relation to childhood CNS tumor risk. Elevated residential ELF-MF (≥0.4 μT) was associated with approximately doubled odds of CNST, while cell phone use showed no association. Prolonged tablet use, with or without internet connectivity, was reported to be associated with higher CNST risk.
