Activity, sleep and circadian changes in flies exposed at 3.5 GHz
The reported finding
Short exposure increased activity and reduced sleep; longer exposure reduced F1 activity and increased sleep, with circadian/heat-stress gene and GABA/glutamate changes.
Reading it carefully
Original abstract only. Authors invoke heat stress; physiological significance and thermal contribution require full methods. A carrier experiment, not established NR exposure.
Inside the study
Technology connection
Relevant mobile-frequency experiment; waveform and dose described in this record.
Publication type
Original journal research
Exposure conditions
3.5 GHz; incident densities 0.1, 1 and 10 W/m²; short- and long-term protocols. Exact durations and thermal controls not audited from full text.
Design & controls
Parent and F1 male Drosophila; activity monitoring, gene-expression assays and neurotransmitter measurements.
Statistics
See reported finding and original tables; effect sizes not independently recalculated.
The protection question raised
Which exposure conditions and biological models reproduce this response, and what would establish its relevance to health?
Source verification
Original abstract and bibliographic metadata checked; full methods and dosimetry not audited.
