“…Nevertheless, Kumar's point remains valid and is therefore valuable, if we were to assess the various university level studies conducted by scientists that have shown proof of harm – if not conclusively – but through fairly robust studies published in peer reviewed journals (A. G. Gandhi & Singh, 2011; G. Gandhi & Anita, 2005; Kesari et al, 2018; Kesari & Behari, 2010, 2012; Sarkar et al, 2006).…”

Public resistance to environmental and health safety risks from radiations emanating from cell phone towers has been sporadic but spatially and temporally widespread in India. Civic actions have been led by civic activists, resident welfare associations, gram panchayats, lawyers, scientists and even an actor from the Bombay film industry. Large scale technical systems like cell-phone towers are remarkably resilient to public criticism. Industry response to such resistance is usually in the form of aesthetic tinkering to hide structures from public gaze, incremental regulation and science communication to assuage public doubt. The legislature rather than Courts has been more responsive to such civic actions. Courts due to their overreliance on risk discourses have continued to defer to State experts. Faced with incrementalism from formal institutional actors, resistance movements have become localized and used site requirements to stymie such developments. Drawing on Beck's idea of subpolitics, this study explores the disaggregated nature of the resistance movement against cell tower radiation in India. It is based on a multi-sited ethnography based on field research and 35 interviews with activists, journalists, regulators, lawyers, industry representatives, doctors and scientists, conducted between November 2017 to December 2019. Jurisprudential developments, parliamentary committee and scientific reports were also reviewed. Subpolitics as a category has purchase in STS studies because it allows us to focus on the disaggregated nature of affected publics and interrogate public engagement with State institutions and new social expectations and solidarities with reference to technology.

Abstract：Acutely isolated mouse hippocampal CA3 pyramidal neurons were exposed to 3 mT static magnetic field, and the characteristics of transient outward K + channel were studied using the whole-cell patch-clamp technique. The experiment revealed that the amplitude of transient outward potassium channel current was reduced. The maximum activated current densities of control group and exposure group were 163.62±20.68 pA/pF and 98.74±16.57 pA/pF(n=12, P<0.01)respectively. The static magnetic field exposure affected the activation and inactivation process of transient outward potassium channel current. Due to the magnetic field exposure, the halfactivation voltage of the activation curves changed from 5.59±1.96 mV to 27.87±7.24 mV(n=12, P<0.05), and the slope factor changed from 19.43±2.11 mV to 25.87±4.22 mV(n=12, P<0.05). The half-inactivation voltage of the inactivation curves also changed from -56.09±0.89 mV to -57.16±1.10 mV(n=12, P>0.05)and the slope factor of the inactivation curves from 8.69±0.80 mV to 10.87±1.02 mV(n=12, P<0.05). The results show that the static magnetic field can change the characteristics of transient outward K + channel, and affect the physiological functions of neurons.In modern life, the increase of electrical instruments induces exposure to electromagnetic fields, and their possible impacts on biological systems are of great interest [1][2][3][4][5][6][7][8][9] .Most of the current research on the effects of nervous system inflicted by magnetic field is based on the levels of entire body or organs of creatures. The patchclamp technique studies from the perspective of cell ion channels [10][11][12] . The voltage-gated ion channel is the molecular basis of the electronic activity of neurons. For instance, transient outward potassium channel current I A is the main component of the outward current in the early stage of action potential repolarization. In addition, the research on the influence of the static magnetic field with several mT magnitude on biological tissue [13,14] , seldom uses the patch-clamp technique skills.In this paper, the effects of 3 mT static magnetic field (SMF) on transient outward potassium channel currents in hippocampal neurons of a mouse were studied using the whole-cell patch-clamp technique. The work was undertaken to probe the possible molecular mechanisms for SMF-induced bio-stimulation effects. Materials and methods Cell preparation and solutionsHippocampal CA3 pyramidal neurons were freshly isolated by enzymatic digestion and mechanical dispersion from 8 -12-day-old Kunming mice (supplied by Tianjin Medical University). The method used here was similar to that of Ref. [15]. Briefly, 400-500 μm thick brain slices were cut from hippocampal CA3 region and incubated for 50 min at room temperature in artificial cerebrospinal solution (ACS, mmol/L) containing NaCl 134, KCl 5, NaH 2 PO 4 1.5, MgSO 4 2, CaCl 2 2, NaHCO 3 25, glucose 10, HEPES 10, pH adjusted to 7.3, continuously bubbled with 95%O 2 +5%CO 2 and successively transferred into ACS containing 0.3 mg...

Acutely isolated rats cortical neurons were exposed to 2450MHz radio frequency (RF) magnetic field, and the characteristics of delayed rectifier potassium channel were studied using the whole-cell patch-clamp technique. The 2450MHz RF magnetic field was obtained by Agilent E5070B net analyzer and a 6dB gain omni directional antenna, and the transmitting power was 39.81mW.The experiment revealed that the amplitude of delayed rectifier potassium channel current was reduced. The maximum activated current densities of control and 5min, 10min, and 25min exposure group were (191.71±29.82) pA/pF, (148.48±22.43)pA/pF, (120.95±17.29)pA/pF and (74.89±11.58)pA/pF respectively(n=10, P<0.05). The half-activation voltage of the activation curves changed from (-1.13±2.32) mV to (19.52±1.03) mV (n=10, P<0.05) and the slope factor changed from (23.21±3.29) mV to (13.95±1.27) mV (n=10, P<0.05). The results show that the low power 2450MHz RF magnetic field can change the characteristics of delayed rectifier potassium channel, and affect the physiological functions of neurons.
