Geomagnetic Field And The Sex Of A Child

29.03.2005


Researchers from St. Petersburg have ascertained that formation of a child’s sex depends, among other things, on the geomagnetic field status at the time of conception.



Who will be born – a boy or a girl? The answer to this question that worries all parents is determined by a lot of conditions, including external ones. The scientists of the Central Scientific-Research Institute of Radiology and Nuclear Medicine, Ministry of Health Care of the Russian Federation (St. Petersburg) and the St. Petersburg branch of Institute of Terrestrial Magnetism, Ionosphere and Radiopropagation, Russian Academy of Sciences (IZMIRAN), have ascertained that the sex of a child depends, among other things, on the level of disturbances of geomagnetic field status at the time of conception.

The researchers have retrospectively analyzed the connection between more than 600 randomly chosen supposed conception instants and the geomagnetic field status within the 1914-1979 timeframe. These instants were mainly inhabitants of St. Petersburg and the St. Petersburg Region. As the exact date of conception is normally unknown, therefore the researchers subtracted 280 days from the date of the child’s birth and determined the geomagnetic field status on that day and on the dates of nearest extremums before and after the supposed conception.


Regardless of the fact that the frequency of the boys’ and girls’ births was on the whole approximately equal within the period under review, some interesting regularities were still discovered. It has turned out that in case of lowering intensity of magnetic field oscillation at the point of conception, boys were borns more frequently (approximately 16 boys per 10 girls), but in case of increasing its intensity – girls were born more frequently (approximately 15 girls per 10 boys).

Can science explain this regularity? The researchers suppose that the discovered dependence is connected with the roles which are assigned by evolution to the male and female sex: the female role is stabilization, the male one - lability, search. That means that in unfavorable environment (in this case – increased level of magnetic field distortion) preconditions for girls’ birth occur in gametal cells, and vice versa, in favorable environment (decreased level of distortion), boys are born.

Such preconditions appearance mechanism is yet unclear. However, the researchers assume that it is connected with the presence of free-radical particles in the cells, fluctuations in ultra-low magnetic fields intensity being able to influence these particles’ recombination processes, and also to affect decay of some types of blood leucocytes, for example, neutrophils, which significantly decrease in number during disturbed geomagnetic activity periods.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
