Satelite Shows Huge Pentagram In Kazakhstan

A satelite image seems to show an unusual symbol in the Denisovsky area of Kazakhstan which looks devilishly like a huge Pentagram. The area concerned is said to be an ‘Unfinished Summercamp’.
Perhaps someone could kindly post a screen shot of the image as I have no clue how to from the site.

An animal unable to breathe and living without oxygen was found for the first time

Inhalation of oxygen is a fundamental characteristic of multicellular organisms. But there is at least one animal that does not have this ability and does without oxygen.

This amazing discovery is reported by an international team of biologists and geneticists in an article published in PNAS.

The organism in question is called Henneguya salminicola. This is a distant relative of jellyfish, a representative of the class Myxozoa – parasitic invertebrates belonging to the striking. The hosts of H. salminicola can be fish or worms that live underwater.

Until now, it was believed that all plants and animals use oxygen to produce adenosine triphosphate (ATP). This is a universal source of energy for all biochemical processes taking place in living systems. ATP generation from oxygen occurs in structures called mitochondria.

Each mitochondria has its own tiny genome in addition to the main one – in the cell nucleus. But when the researchers performed a genomic analysis of H. salminicola, they did not find mitochondrial DNA.

At first, the scientists decided that they had made some kind of mistake. However, further tests using a fluorescent dye that selectively binds to DNA confirmed the data.

The authors explain: although representatives of H. salminicola have organelles similar to mitochondria, they lack the genes responsible for respiration. In the body of the parasite, enzymes necessary for the production of ATP from oxygen are not produced.

Thus, H. salminicola is the first known multicellular one that can do without oxygen throughout its entire life cycle.

It remains unknown why the parasites lost their ability to breathe oxygen, but their immediate family did not. Probably, having reduced their genome, H. salminicola gained an important advantage: they thrive, reproducing as quickly and as often as possible, the authors of the research wrote.

In addition, it is unclear how this multicellular receives the necessary energy. Most likely, H. salminicola steals it from the host, the researchers suggest. Other similar parasites have proteins that help import ATP directly from infected animals. In the future, scientists intend to find out whether H. salminicola uses the same strategy.

We add that H. salminicola is harmless to humans, but it is a serious problem for fish farming, since it also parasitizes on commercial fish, for example, salmonids. Perhaps the new data will help experts understand how to protect fish from these strange parasites.

Coronavirus was mentioned in a popular 2017 comic

The character in the popular comic was named after the coronavirus three years before the deadly outbreak in Wuhan. In the comic strip Asterix and the Chariot Race, published in 2017, the masked villain who took part in the event was mysteriously named after the virus.

The original comic was released in Italy two years before the first cases of the disease appeared in Wuhan (China) in December 2019. In it, Asterix and his assistant Obelix participate in a chariot race organized by Julius Caesar. The couple have to compete with the villain Coronavirus and his henchman Bacillus.

A meteorite that fell in Germany turned out to be a “mini-planet”

Scientists at the University of Münster in Germany identified a celestial body that fell near Flensburg in September 2019. It turned out that this is not just a meteorite, but the “germ” of the planet – planetesimal, the University of Muenster reports.

The space “guest” was discovered by a local resident in his garden. The weight of the fragment covered with a black melted crust was only 24.7 grams.

The find was studied by representatives of one and a half dozen universities and research centers. Analyzes showed that the rock contains minerals, including silicates and carbonates.

It is known that such substances arose at the very beginning of the history of the solar system on small protoplanets, where water was also present. Many scientists believe that it was the planetesimals that once brought moisture to our Earth.

The authors of the study said that this is the first case of the fall of such a cosmic body in Germany. Its age can be 4.56 billion years or more – that is, it is the same age as the Earth. In the past, it really contained liquid water – this confirms the theory of moisture saturated planetesimals.

Scientists intend to continue to study the object. In their opinion, it may reveal unknown details of the history of the formation of planets in the solar system.
