EFFECTS ON BIRDS. “Although there are considerable reports of magnetic field effects (MFE) on organisms, very little is known so far about the MFE-related signal transduction pathways. Here we establish a manipulative near-zero magnetic field (NZMF) to investigate the potential signal transduction pathways involved in MFE. We show that exposure of migratory white-backed planthopper, Sogatella furcifera, to the NZMF results in delayed egg and nymphal development, increased frequency of brachypterous females, and reduced longevity of macropterous female adults.” https://lnkd.in/ggMJNzs View in LinkedIn

EFFECTS ON BEES. “The effects of a time-compressed simulated geomagnetic storm (TC-SGS) on the nest-exiting flight angles of another stingless bee, Tetragonisca angustula, are presented. Under an applied SGS, either on the horizontal or vertical component of the geomagnetic field, both nest-exiting flight angles, dip and azimuth, are statistically different from those under geomagnetic conditions.” https://lnkd.in/dv_w-gS View in LinkedIn

FISH ENZYME CHANGES. “It has been demonstrated that the glycosidase activity of cyprinoid fishes (carp and crucian carp) exposed to a geomagnetic storm for up to 20 h considerably decreases.” https://lnkd.in/dbdexkF View in LinkedIn

CARDIOVASCULAR EFFECTS. “One study observed that in years of peak GMS activity, patients admitted for myocardial infarction increased 25 per cent; other studies have reported a similar relationship, accounting for a 5 per cent increase in mortality in maximal solar years. Moreover, these epidemiological studies are supported by evidence from both human and animal physiological studies that reveal changes to blood pressure and HRV in relation to geomagnetic disturbances.” (GMS = geomagnetic storms). http://rspb.royalsocietypublishing.org/content/early/2012/03/12/rspb.2012.0324.short View in LinkedIn

VESTIGIAL SENSE. “There is evidence suggesting that such a magnetosense—or at least the vestiges of it—may exist in humans.” http://rspb.royalsocietypublishing.org/content/early/2012/03/12/rspb.2012.0324.short View in LinkedIn

EFFECTS ON MAN. “A controversial body of literature demonstrates associations of geomagnetic storms (GMS) with numerous cardiovascular, psychiatric and behavioural outcomes.” (GMS = geomagnetic storms). http://rspb.royalsocietypublishing.org/content/early/2012/03/12/rspb.2012.0324.short View in LinkedIn

GEOMAGNETIC STORMS. “Six physiological parameters of cardio-vascular system of rabbits and ultrastructure of cardiomyocytes were investigated during two planetary geomagnetic storms. At the initial and main phase of the storm the normal circadian structure in each cardiovascular parameter was lost. The asynchronicity was growing together with the storm and abrupt drop of cardia activity was observed during the main phase of storm.” (1995). http://www.ncbi.nlm.nih.gov/pubmed/8555294 View in LinkedIn

MAGNETIC EFFECTS ON HORMONES. “It is hypothesized that the cryptochrome compass system is mediating stress responses more broadly across the hypothalamic–pituitary–adrenal (HPA) axis (including alterations to circadian behaviour) in response to changes in the GMF. It is therefore proposed that GMS lead to disorientation of hormonal systems in animals and humans, thus explaining the effects of GMS on human health and behaviour.” (GMS = geomagnetic storms; GMF = geomagnetic field). http://rspb.royalsocietypublishing.org/content/early/2012/03/12/rspb.2012.0324.short View in LinkedIn

STROKE STUDY. “To the best of our knowledge, this study is the largest to date, a sufficiently statistically powered, individual-participant population-based stroke incidence study of the effects of geo-magnetic activity on the risk of first-ever stroke and major pathological stroke types across different populations and age groups. We showed that although geomagnetic storms can account for only 2.64% of all strokes on a population level, exposure to geomagnetic storms (with Ap Index >60) on an individual level increases the relative risk of stroke by 19% across all ages.” https://lnkd.in/djUc-ZC View in LinkedIn
