Scientists sound the alarm: Bloody snow in the Alps is a harbinger of a global catastrophe
People who often visit the mountains are shocked by the rapid change in the shade of the surrounding landscapes. Climatologists came to investigate the situation.
Who covered the snow with blood?
Out of habit, inexperienced travelers sometimes get scared. And although such a picture has been observed in the mountains since ancient times, in recent years it has begun to disturb even seasoned tourists. And even more bloody landscapes interested climate experts. They noticed that in the French Alps, more and more wide open spaces are acquiring a peculiar shade.
It is widely known that microscopic algae living in the snow create the impression of the consequences of the massacre. For example, these are.
Creatures in thousandths of millimeters in size have adapted to live between snowflakes at temperatures that fluctuate around zero. As scientists suggest, they are distributed by animals and, possibly, air transport. But there is a version that in fact their ancestors settled in the mountains back in the late Proterozoic, that is, more than 600 million years ago, when the planet was almost entirely covered with ice.
Why are is it red?
They contain a special pigment similar to the one that gives the red color of carrots - astaxanthin. It is he, by the way, that makes crabs, shrimps red, gives the famous color to salmon and trout meat. Finally, it also decorates amazing pink flamingos. Astaxanthin is good because it protects against solar ultraviolet radiation, which, of course, is very important in hot countries. But lately it has become more and more important in the snowy regions.
What's wrong with them?
In 2016, French microbiologists climbed the mountains to a height of almost three kilometers and collected samples of two species of red microalgae there: Sanguina nivaloides and Sanguina aurantia. It is curious that the first of them actually live all over the planet, but the second - only in the Northern Hemisphere and, moreover, clearly prefer the Alps.
But both of them settled at an altitude of two kilometers. This is quite logical: there is more ultraviolet radiation at the top, so algae without a protective substance would be uncomfortable there. But still the question remains why there are so many of them. And the answer is simple: photosynthesis takes place in these algae, that is, the absorption of carbon dioxide and the production of oxygen. And as you know, the notorious global warming is primarily to blame for the excess of CO2. The abundance of this greenhouse gas could not help but please photosynthetic creatures.
It would seem, well, good health. But there is a nuance. If the snow turns red, it darkens, which means it absorbs more sunlight and heat. As a result, it heats up and melts more. It turns out that climate change is proceeding like a bloody snowball: carbon dioxide - warming - algae bloom - accelerated melting of ice - even stronger warming.
The newest symptom of coronavirus infection is the appearance of red spots or a transient form of hives. This is the conclusion reached by several experts, dermatologists in the National Union of Dermatologists-Venerologists in France.
We all know that among the most common symptoms of coronavirus infection are dry cough, fever and respiratory difficulties. There are, however, other signs that tell you something is wrong, but these occur sporadically and not all patients experience them. These include loss of taste and smell, irritated and teary eyes, sore throat, and, more recently, the appearance of reddish spots, sometimes painful but also hives. This is the conclusion reached by several French doctors who thus sound an alarm.
The National Union of Dermatologists-Venerologists in France warns in a press release about the symptoms that may appear on the skin in case of infection with Covid-19. "A WhatsApp group of over 400 dermatologists, organized by the National Union of Dermatologists-Venerologists in France, indicates skin lesions, whether or not associated with other Covid symptoms," the press release states. Dermatologists detail the symptoms in question: acrosindromas (pseudo-degeneration in the extremities), the sudden appearance of sometimes painful red spots and transient episodes of hives.
The dermatologists' union suggests that if these skin symptoms occur, consult a specialist doctor as soon as possible. The analysis of the numerous cases reported shows that these symptoms can be associated with Covid-19. "We alert the public and physicians to detect these potentially contagious patients as soon as possible (they do not necessarily show signs of breathing difficulties)," the statement concludes.
The Spaniards were frightened and returned to harsh measures. Spain decided on Wednesday (May 6th) to extend the state of emergency for another two weeks. That was after it was given free to walks and physical activities.
Prime Minister Pedro Sanchez called on the parliament, which approved the measure, after easing the restrictions, bringing the number of cases of illness to 3,121 on May 6. This is after, after the end of April and the beginning of May, they had stabilized at 850 -1,200 new cases per day.
Spain has registered 256,855 cases of COVID-19 disease and over 26,000 deaths. The Sanchez government wants to gradually lift the measures of isolation at home and at the same time control the implementation of measures of social distancing and hygiene among the population.
Home isolation was imposed on March 14 and the state of emergency was due to end on Saturday, May 9, but will be extended until May 24. Although the opposition claimed that 60 days of state of emergency were illegal, it had to vote on the law for national security.
Belgian Llama’s immune system could be the key to treatment for the new coronavirus. Belgian researchers have found that her body can produce antibodies that could stop COVID-19. Scientists have already continued research into the fight against SARS and MERS, when US scientists discovered that the animal has developed immunity to both types of coronavirus.
He is four years old, lives on a farm in Belgium, has brown chocolate fur and could be the key to an effective drug for Sars-CoV-2 coronavirus. Researchers have recently discovered that antibodies in her blood can stop the virus. Other tests are now being done to see if they can be used in the future to help people with coronavirus.
Belgian Llama already contributed to research in the fight against coronavirus in 2016. At that time, scientists at the University of Ghent, the University of Texas at Austin (UT Austin, USA) and the National Institutes of Health in America examined two previous forms of the agent. pathogen - SARS-CoV-1 and MERS-CoV. They found that llama’s blood developed antibodies in a type of immunization therapy that successfully fought both forms.
The human body can produce only one type of antibody, while the blades produce two types. These antibodies are similar, but one of the types of antibodies produced by the slides are several times smaller.
"Llama’s antibodies are easy to handle," said Dr. Xavier Saelens, a molecular virology specialist at the University of Ghent.
This is what the school looks like during the coronavirus pandemic . What rules should students in Germany follow?
The pandemic that took over 250,000 lives in just four months and contaminated over 3.7 million earthlings turned everything upside down! On Monday, May 4, schools in Germany opened their doors. But the traditional noise during breaks did not resound in the hallways. The children obeyed the rules imposed by the COVID-19 terror.
Before the pandemic, school and high school courtyards resounded with the merry laughter of children. German Chancellor Angela Merkel has ordered schools and high schools to open on May 4, after closing their doors in early March.
But the children discovered a rigid environment, in which the rules imposed by the measures to prevent the spread of the new coronavirus put play, jokes and childhood in the background. The 10th grade students at the Schillerschule in Ettlingen have been preparing for exams since last week. On Monday, May 4, the little ones from the gymnasium and primary school also showed up at the same school.
The hallways of the school were marked with yellow stripes and posters with strict instructions were mounted on the walls: keeping a distance of 1.5 meters, using face masks, gloves and regular hand washing.
According to Deutsche Welle, only children in the final grades were able to go to school on May 4, to avoid the congestion of educational institutions. The benches for two students were used for one child and the whole school is subjected to a strict disinfection ritual performed at three key times of the day: in the morning, at noon, between shifts and in the evening. At the entrance to the classrooms, pumps with alcohol-based disinfectants were installed.
The fear in the souls of parents who send their children to school is indescribable. And in China, primary and secondary schools opened their doors on April 27. Even high school students were able to return to campuses on April 27, and students will resume classes on May 11. The rules for distancing and preventing the spread of the new coronavirus are strictly observed. In primary school, parents made children's one meter long sticks to be worn as "wings" on the back that would force other classmates not to get closer than a meter.
Dogs performed many important operations, which contributed to the salvation of soldiers in the war. About what operations were assigned to animals Bemorepanda is ready to surprise you.
Intelligence activities could not do without dogs: dogs escorted scouts behind enemy lines, avoiding ambushes, traps and other secrets of the battlefield.
Animals worthily performed the work of watchmen, soundlessly indicating the appearance on the horizon of the enemy by pulling a leash and turning the body in the right direction.
Known merits of dogs in the field of sabotage. So they caused the enemy some logistic problems, undermining bridges and trains. In addition, the four-legged gave their lives to inflict heavy damage on enemy war machines.
Specially trained dogs, during the war, sought out seriously wounded soldiers in hard-to-reach places and brought orderlies to them.
The difficult situation greatly complicated the usual communication, so dogs were used to convey reports. For all the time they delivered more than 120,000 reports and paved 8,000 km of telephone wire.
The task of no less importance is to find an explosive device planted by the enemy, which the four-legged animals did very well.
