The new Russian coronavirus can be transmitted to humans and is resistant to vaccines

A team of researchers from Washington State University has discovered a new type of coronavirus found in bats in western Russia that can not only infect human cells but is also resistant to SARS-CoV-2 vaccines. The study, published in the specialist journal PloS Pathogens, claims that the new virus, called Hosta-2, is part of the coronaviridae family, just like SARS-CoV-2.

The Hosta-1 and Hosta-2 variants have been discovered since late 2020, but initially appeared to be harmless to humans. In fact, hundreds of variants of the coronavirus have been identified in recent years, mostly in bats from various regions of Asia, but they are harmless and cannot infect human cells.

Like spinach, the Americans discovered that this Russian virus could infect people exactly two days after Russia announced a partial mobilization, no word, it could just be a coincidence. Certainly, the Hosta-2 variant appears to be resistant to anti-covid vaccines, as well as to antibodies produced by people infected with known variants of the coronavirus.

It is also impossible to say what mutations it can generate if it recombines with SARS-CoV-2. The Americans also say that in view of this discovery, there is an urgent need to create universal vaccines that protect against all coronaviruses. Yes, thanks, we knew that too!

We are slowly but surely becoming a green planet. And that’s not good

As temperatures continue to rise, the planet’s lakes are changing color. This is stated in a study published yesterday in the journal. Letters of geophysical research. More precisely, from blue lakes become green, in some cases even brown.

Researchers involved in a research project that analyzed nearly 5.4 million satellite images to monitor the situation of 85,360 lakes show us that the situation is indeed grim. In fact, such a global observation was made for the first time. And it turned out that against the background of global warming, algae have a tendency to develop alarmingly, and it is they who give the mentioned colors.

It would not be a big problem to change the color of the varnish. The problem is that aquatic ecosystems are under threat, the quality of water is decreasing… fish and other animals will also have nowhere to live, but we will also have no water to drink. Please you will, but it will cost you, it will sting you, because the treatment will be extremely expensive. Then, researchers say, would you rather swim in a green lake or a mostly brown one?

Nanorobots are being formed. They just cured pneumonia in mice

Nanobots, or microscopic robots or microrobots, capable of injecting antibiotics, isolating and killing the pneumonia-causing bacterium Streptococcus pneumoniae have just been successfully tested on laboratory mice, a team of researchers from the University of San Diego reports in the journal Nature Materials.

Lest you think that they want to introduce you to who-knows-what miniature robots armed with mini-missiles and mini-machine guns, it should be noted that the nanobots created by the aforementioned Americans are made of cells collected from algae, and their surface is equipped with nano-particles of antibiotics that are biologically decompose in a few days. Therefore, the nanobots swim to where they are needed, in this case the lungs, releasing those antibiotics that are made from biodegradable polymers similar to white blood cells. They specialize in isolating and destroying harmful bacteria, and then, having done their job, they also disappear without a trace. What more could you wish for?

Experts also say that the dose of antibiotics used in the case of nanorobots is several times lower than in the case of classical treatment. By the way, the success rate was 100% on mice. Mortality of untreated mice was also 100%. More interestingly, treatment with nanorobots is not new. Similar methods of treating stomach and blood infections already exist. At the moment they are still in the testing phase, there are still some details related to how they interact with the natural immune system, but it will be worked out, don’t lose patience.

This is the medicine of the future! You treat yourself to a glass of these nanobots and while you’re sweeping the house while you’re watching the game on TV, the pathogen has just been destroyed. You will be proud when you tell your grandchildren what an epoch-making moment you experienced.

Mayan cities were contaminated with mercury

Several Australian researchers from the Catholic University of Australia say in a study published in Frontiers in Environmental Science that many Mayan cities still have traces of mercury contamination at dangerous levels.

In this way we learn a new fact, namely that the Mayans used mercury for hundreds of years, from about 250 AD to be exact. and until about 1100 AD when they disappeared. There is a small possibility that he left because of mercury, but they did not manage him either. The Maya used a red mineral called cinnabar combined with mercury to make dyes that they used in everything from pottery to home decorations. Once in the soil and water sources, the mercury, as expected, led to pollution and serious health problems for local residents.

That’s how bad the contamination was even today at the Tikal site, the contamination level is 17.16 parts per million (ppm), where 1 ppm is already considered a toxic level. Exposure to this level of toxicity would cause disorders of the central nervous system, kidneys, liver, eyes, leading to paralysis or mental problems. It may not be a coincidence, experts say, that some of the last Mayan leaders appear in images as obese, another consequence of mercury contamination.

Now, after this discovery, researchers also want to know if mercury contamination played any role in the socio-cultural processes at the end of the Maya civilization. Not likely, but here’s also a new track worth exploring.
