Highlights

• • Microwaves at 2.4 GHz are fundamental to today’s wireless communication (e.g., 4G, WiFi).

• • The non-thermal effects of 2.4 GHz microwaves on biological systems are controversial.

• • 2.4 GHz microwaves eliminated the response of human heart cells to β-AR stimulation.

• • Microwave-disrupted calcium signalling promoted spatially-clustered apoptosis.

• • The destructive effects of 2.4 GHz microwaves were mediated by non-thermal mechanisms.
