The sun affects the emergence of large-scale epidemics on Earth

A Serbian scientist saw a correlation between weak ultraviolet radiation and the emergence of large-scale epidemics of infectious diseases. Images from American satellites confirm that the ultraviolet radiation of the sun or the disinfection of the atmosphere at the time when COVID-19 appeared was even weaker than during the period of H1N1 propagation.

Let’s recall the 2009 H1N1 flu pandemic. It spread, despite all the efforts of the World Health Organization. Of course, nothing could be done with this epidemic, since it erupted during the period of the weakest solar radiation. After all, just as after surgery, the surgical room is sterilized with ultraviolet lamps, the atmosphere of the earth naturally sterilizes ultraviolet solar radiation.

Low radiation and epidemics

The founder of heliocentric electromagnetic meteorology Milan Stevanchevich saw a correlation between weak ultraviolet radiation and the emergence of large-scale epidemics of infectious diseases. Although NASA has not yet linked these phenomena, images from American satellites confirm that the ultraviolet radiation of the sun at the time the coronavirus appeared was even weaker than during the period of H1N1 propagation. In 2009, the level of ultraviolet radiation of the sun was eight units, and in 2019 – only five units. The lack of ultraviolet radiation, that is, disinfection of the atmosphere, in both cases led to the unhindered spread of the virus in the northern hemisphere.

Seasonal character

The Belgrade School of Meteorology believes that the level of ultraviolet radiation is also seasonal. In winter, the level is much lower than in summer. During maximum solar activity, ultraviolet radiation reaches 35 units. But in the period between two cycles of solar activity, ultraviolet radiation reaches the lowest levels or disappears.

Milan Stevanchevich explains:

​​“On March 11, the outbreak of AP 2758 on the Sun caused an increase in ultraviolet radiation. In the geoeffective position, one x-ray emission was recorded, which became the first after more than 300 days of inactivity of the Sun.”

When a flash on the Sun occurs on a side not visible from Earth, the level of ultraviolet radiation decreases. Its next growth is expected in early April 2020, and entry into a geoeffective position is expected on April 7, when the radiation will be sent directly to the Earth.

The level of ultraviolet radiation at the surface of the earth depends on the radiated power and density of the clouds over a particular place. Although ultraviolet radiation has a diffuse nature, the influence of clouds is great, since they reduce the level of ultraviolet radiation above the surface of the earth. Water in the atmosphere is an element that creates the effect of a greenhouse, so exposure to ultraviolet radiation also depends on cloud cover. Clouds weaken all types of energy emanating from the sun.

An increase in temperature does not play any role in the disinfection of the atmosphere, so flu can appear even when the daytime temperature is high.

Ultraviolet radiation is a natural phenomenon that makes possible the existence of man on planet Earth. But strong ultraviolet radiation is very dangerous for human health. Fortunately, nature has provided for everything. When activity on the Sun grows, cloudiness intensifies, as clouds are formed by the combination of hydrogen and oxygen, which are emitted by the Sun, and therefore the level of ultraviolet radiation decreases.

It is expected that weak X-ray radiation will reach a maximum on April 7, when the AP 2758 volcano appears on the visible side of the Sun, which disinfects the atmosphere more. No matter how weak the effect of x-rays, it plays a large role in the total radiation of the sun.

Studies show that pandemics can occur only between periods of two activity cycles, when the activity of the Sun is minimal, that is, when the level of ultraviolet radiation in winter is the lowest. Epidemics occur only at the beginning and at the end of the solar cycle. Seasonal influenza with variable variability depends on the current activity of the Sun. The weakest viruses in the period of maximum activity of the Sun.

For the disinfection of the atmosphere, the angle of incidence of ultraviolet and x-ray radiation plays a large role, since the level of radiation per unit area during the day depends on it.

It must be said that the transition period between the 24th and 25th cycles of solar activity is exceptionally long. The activity of the Sun reached an extraordinary minimum. The level of activity of the Sun in 2019 – 2020 is the lowest since 1810. Temperature has no effect on COVID-19.

If NASA’s forecast comes true, then in ten years we should expect another mutation of the virus.

Geologists have confirmed a strange unprecedented “boomerang” earthquake deep under the Atlantic Ocean

Earthquakes come and go, often leaving destruction behind. What they luckily don’t usually do is turn around immediately and come back for another push. Except … it looks like they can do it on very rare occasions.

In a new study, scientists have uncovered evidence of an unusual and almost unprecedented boomerang earthquake that shook the deep seafloor under the Atlantic Ocean in 2016.

This earthquake, dubbed “reverse super-shear rupture”, occurred along the Romansh fracture. It is an area that lies near the equator, about halfway between the east coast of Brazil and the west coast of Africa.

The rift, which stretches about 900 kilometers between the South American and African tectonic plates, adjacent to the Mid-Atlantic Ridge, caused a 7.1 magnitude earthquake in August 2016, which was detected by underwater seismometers in the region, as well as by remote monitoring stations.

Analysis of the signals reveals that this was not an ordinary earthquake, but a strange earthquake that went one way before turning around and returning and with a significant increase in speed.

“While scientists have found that this reverse rupture mechanism is possible on the basis of theoretical models, our new study provides some of the clearest evidence that this mysterious mechanism actually occurs,” Stephen Hicks said, lead researcher and seismologist of Imperial College London.

According to the analysis of seismic data, the 2016 earthquake had two separate phases.

First, the rip extended upward and eastward towards the weak point where the rip zone meets the Mid-Atlantic Ridge. Then, in a sudden U-turn, an “unusual westward propagation” occurred, with the tremors returning to the center of the fault and at significantly accelerated “super-shear” velocities of up to 6 kilometers per second.

“Even though the structure of the fault appears to be simple, the quake grew differently, and it was completely the opposite of how we expected the quake to look before we started analyzing the data.”

While the team’s explanation for how this boomerang unfolded remains speculative so far, the researchers speculate that the first, deep phase of the quake released enough fracture energy to initiate a reversal of the rift in the shallower, western underwater terrain.

“Either both sections of the fault were preseismically loaded enough to promote seismogenic failure, or the deeper SE1 fracture instantly increased static stress, immediately causing the shallower portion of SE2 to collapse,” the authors explain in their paper.

Although earthquakes propagating in the opposite direction have been studied by seismologists before, so far there has been little evidence of their existence, and this phenomenon is mainly observed in theoretical modeling.

Finding this type in the real world – in the middle of the ocean – is the first of its kind, not to mention the boomerang that returned at super shear speed.

“To my knowledge, this is the first time this has been reported,” geophysicist Yoshihiro Kaneko of GNS Science in New Zealand, who was not part of the research team, told National Geographic.

The results are reported to Nature Geoscience.

What is the real cause of explosions and fires around the world in the past few days?

What has caused all these giant explosions and apocalyptic fires in China, North Korea, Lebanon, India, USA, Iraq, Iran over the past few days?

China

It all began on August 3, 2020 in the Chinese province of Hubei, where an instant explosion at a chemical plant killed at least six people and injured four. The reason is under investigation.

North Korea

This first explosion was followed a few hours later by a giant explosion following a possible “gas leak” in Hyesan, Yangan Province, North Korea, killing 9 people and injuring at least 30 residents. The reason is being investigated.

Lebanon

The next day, the port area of ​​Beirut, Lebanon, was destroyed by a giant explosion, killing more than 140 people and injuring thousands.

India

Also on the afternoon of August 4, 2020, an explosion caused panic among residents living around the Vijayshree Pharma Company plant in the Rambilli Zone FEZ in Vishakhapatnam in Andhra Pradesh, India. The reason is being investigated.

Great Britain

On 4 August, an explosion occurred again in the middle of a residential street in Birmingham, UK, causing smoke and fireballs to rise into the air and residents fleeing to seek refuge. The explosion was so strong that fire alarms went off in the houses.

United States of America

Finally, on Tuesday, firefighters put out a massive fire in downtown St. Paul, Minnesota, that engulfed a building under construction. When the firefighters arrived at about 4:20 am, the flames were flying high into the air, and the glow was visible for miles.

Iran

A fire broke out on Tuesday inside three industrial warehouses east of Tehran. The fire destroyed production materials, including lumber and leather.

Then, on August 5, at least seven ships burst into flames at a shipyard in the southern Iranian port of Bushehr. According to reports, the reason remains unclear, no casualties.

United Arab Emirates

On 5 August 2020, on Wednesday evening at 18:30, a fire broke out in a market in the emirate of Ajman, 50 km from Dubai, in the United Arab Emirates. The reason is being investigated.

China

A gas pipeline exploded and several roads collapsed after torrential rains flooded parts of Yulin, a city in China’s northwestern Shaanxi province. Local authorities evacuated about 600 people from the area. The reason is being investigated.

United States of America

On the same day in Midland, Texas, an investigation is under way of an explosion and subsequent fire in an oil storage facility. The reason is also unknown.

Iraq

Again, on August 6, 2020, a major fire broke out in over 20 wholesale market warehouses in Najaf, Iraq. The reasons are being investigated.

Geneticists have clarified the origin of American slaves

Frame from the movie "Django Unchained" - imdb.com

It is the largest study of DNA from people living in the Americas. It shows where the slaves came from in the United States and reveals the details of their abuse.

The work includes information on 50 thousand people, of which 30 thousand are of African origin. The article, published in the American Journal of Human Genetics , serves as “evidence that genetics can shed light on history,” said Alondra Nelson, professor of social sciences at the Institute for Advanced Study in Princeton.

The study began with the work of Joanna Mountain, senior director of research at the company 23andMe. Together with the team, she created a genetic database, which included mainly information about the company’s clients, whose grandparents were born in regions where slavery flourished. Dr. Stephen Micheletti, the geneticist at 23andMe who led the study, compared it to data from the Slave Travels digital project, which contains information about the people brought in: information on ports of embarkation and disembarkation, the number of enslaved men, women and children. He also collaborated with historians to learn more about the plight of African regions, such as contemporary Angola and the Democratic Republic of the Congo, in the 17th and 19th centuries.

Scientists have found out: the DNA of the study participants from the United States showed their Nigerian origin. This means that there are far more ships that transported enslaved people directly to America from Nigeria than would be expected based on historical records. 

At first, historians “could not believe how many Nigerian ancestors were there in the United States,” Micheletti said. 

Later, after consulting with experts, the study authors learned that slaves were first sent to the British Caribbean Islands, and only then sold to the Americans.

Experts estimate that more than half of the people were brought into the United States and Latin America from West Africa. The study found that the modern black population is genetically related to six regions, among them Senegal, Gambia, Nigeria and Benin. Moreover, according to historical sources, there were more regions from which slaves were exported.

The work also showed that the brought women made a much greater contribution to the modern gene pool than men, although there were much fewer of them. Scientists have calculated that in the United States there are 1.5 times more descendants of slaves, and in Latin America and the Caribbean – 13-17 times. Moreover, in the United States, European men have influenced the modern gene pool of people of African descent three times more than European women, and 25 times more in the Caribbean.
