A cold virus can infect a pregnant woman’s fetus

A cold virus can infect a pregnant woman's fetus 86

The study showed that the expectant mother is able to transmit a respiratory tract infection to her unborn child.

Scientists from Tulane University (Louisiana, USA) received the first evidence that the cold virus, which affects a pregnant woman, can penetrate the placenta and infect the fetus. An article about this has been published in PLOS One .

The placenta, an organ that develops in the uterine cavity of a woman during pregnancy, provides the necessary nutrition from the mother to the embryo and simultaneously performs another important task: it filters out potential pathogenic microorganisms. However, a group of pediatricians led by Professor Giovanni Piedimonte found that this natural “barrier” is not so impenetrable.

Scientists took the placenta from donors, isolated three main types of cells – cytotrophoblasts, fibroblasts and Kashchenko – Hofbauer cells – and in vitro exposed them to the human respiratory syncytial virus, which causes respiratory tract infections. Although cytotrophoblast cells supported a weak process of the spread of the virus, two other types were more susceptible to infection. So, Kashchenko-Hofbauer cells survived and allowed the virus to replicate inside the cell walls. According to scientists, then these cells, moving inside the placenta, are able to transmit the virus to the fetus.

“Such cells do not die after they become infected,” Piedimonte explains. – When they enter the fetus, they are comparable to bombs stuffed with a virus. They do not spread the virus in the area of ​​the “explosion”, but carry it through the intercellular channels. <…> Thus, our theory is confirmed that when a woman gets a cold during pregnancy, the virus that causes the infection can pass to the fetus and cause a pulmonary infection before the birth of a child. ”

Pediatricians also suggested that the respiratory syncytial virus is able to infect the lung tissue of the unborn baby and provoke the development of an infection that will subsequently affect the predisposition to asthma. To confirm or refute their theory, the authors of the study intend to conduct clinical tests.

Last year, scientists from the University of Cambridge created an artificial and functional mini-placenta using trophoblasts, and recently it turned out that particles of air pollution can penetrate the placenta of pregnant women

The goal of human civilization is to create AI and disappear?

The goal of human civilization is to create AI and disappear? 87

Various sources often talk about civilizations that lived long before us. They all developed, prospered for a while, and then disappeared in an incomprehensible way. 

What is the reason for their decline, we probably will not know. All we can do is admire the remains of stone buildings, over which time has almost no power.

While looking for an answer, we somehow accidentally stumbled upon an interesting saying about the life of Japanese samurai: “A samurai has no goal, but a path.” In the end, the “path of the samurai” ended in what is known – death. The path of any civilization ended in the same way.

If you look at the issue through the prism of a samurai saying, then there is no point in looking for why and how civilization ended its existence. Probably, the process itself and its result are important here. But to whom is it important and what result does it expect?

Mysterious director

Apparently, behind the curtains of this “ancient theater” there is a mysterious “director” who periodically makes necessary adjustments to the history of civilization.

To figure out what’s what, you need to look at current trends in science. Where does a person strive with such an irresistible desire to “play God.” This attracts him and at the same time frightens him, but in no way turns him away from the intended path. Most likely, artificial intelligence (AI) is the purpose of our civilization’s existence.

About 50 years ago it would have seemed nonsense, but to someone, perhaps even now. However, if you trace the last 100 years of the life of our civilization, you get the feeling that most of the discoveries were given to mankind at the same time. A powerful leap has taken place in a hundred years. Why did it happen?

At the beginning of the last century, scientists recognized the existence of fields that have memory and the ability to store and transmit information. It is very likely that such or a similar field can be around the Earth and, more interesting, possess intelligence. Isn’t this the same “Director” hiding behind the screen of the “ancient theater”?

If this is so, then at a certain moment the “Director” gives the selected scientist “access” to certain knowledge (perhaps even in a dream, like Mendeleev), and another scientific breakthrough occurs in the world. Step by step, discovery after discovery, humanity is steadily moving towards the creation of AI. The trend is already well visible.

AI is probably the next “Babylon”, which will combine all the knowledge, culture and accumulated experience of civilization. In the future, the neural network will enter into a connection with the general information field and leave humanity without knowledge, technology, and even a spoken language. This will be the next decline of civilization. And the “Director” will receive another array of new data (experience) in order to start creating a new civilization.

If someone believes that past civilizations ended in large-scale conflicts, then most likely this is already the consequences of “turning off” AI.

llinn, said that the development of artificial intelligence (AI) threatens humanity. According to him, humans face three key threats, but it is AI that should be feared most of all, the expert said. 

Tallinn explained that at the moment, no one can predict what development AI will achieve in the next decades. In addition, the fact that scientists are creating artificial intelligence that can form a new AI without human intervention is also a cause for concern.

In addition, as the co-founder of the popular video calling service noted, the development of synthetic biology also causes concern. According to him, this direction in science allows the creation of artificial DNA sequences and biological systems that may not exist in nature.

Tallinn also drew attention to the fact that he fears we are entering an era of “unknown unknowns”, things that people are not even able to imagine right now.

Volkswagen robot will autonomously charge cars: a working prototype presented

Volkswagen robot will autonomously charge cars: a working prototype presented 90

The renowned German car manufacturer announced a new development. This time, engineers have created a unique robot capable of autonomously charging electric vehicles. 

For more than a year, specialists have been developing this project, but only now the concern was ready to demonstrate the first working prototype. The robot is ready to charge electric vehicles and has shown the high efficiency of this process.

It is called the Mobile Charging Robot, and experts have already compared it to the R2-D2 droid from Star Wars, including squeaks and clangs. Indeed, there is a similarity. Before implementing this idea, the engineers decided that robots should be allowed to charge cars parked in large residential complexes.

This will save their owners from leaving in order to find a gas station. Another advantage is that large parking lots and garages do not have to contain several expensive charging points for electric cars. The car company said in a press release that the robot works exclusively autonomously.

It independently controls and interacts with the vehicle being charged. It opens the cover of the charging socket and independently connects the power plug, then disconnects it. The robot looks like a trailer, which is a mobile energy storage.

It is capable of charging multiple electric vehicles at the same time. Despite the fact that the manufacturer confidently praises its concept, experts saw inefficiency in the fact that first it is necessary to charge the robot’s battery, which is then used to recharge electric cars.

Volkswagen Group Components CEO Thomas Schmall noted that creating an efficient charging infrastructure for the cars of the future is an important step in the company’s development.

Its engineers focus on finding solutions to avoid costly do-it-yourself measures. The mobile robot is only part of the concept that will continue to be developed.

This video will forever change the way you think about time

This video will forever change the way you think about time 91

Business Insider, one of the world’s leading news portals, made a three-minute video that depicted the Earth’s timeline as a journey from Los Angeles to New York.

So, the beginning of the journey is 4.54 billion years ago, when the Earth was formed from the accumulation of gases and stardust. After some time, a significant event occurs – a giant space body crashes into the still not cooled Earth, as a result of which the breakaway part becomes its satellite – the Moon.

Further, the route runs through the mountains of Arizona, formed about 3.95 billion years ago. A few more kilometers to the east and we are at the 3.8 billion year mark. This is where the first evidence of life in the form of replicating molecules appears.

The next “stop” Kansas – 2.7 billion years ago. Cyanobacteria that produce oxygen appeared on Earth. It took the next 200 million years for the atmosphere of our planet to accumulate sufficient reserves of this most important gas.

Halfway through, we reach Pennsylvania. We are separated from it “only” by 660 million years. Life is developing rapidly: the Earth is covered with vegetation, amphibians are evolving. Unusual time travel is coming to an end – to the point “Now”. By the time the dinosaurs become extinct, we finally reach the outskirts of New York.

And where is the most important thing – people? To find out, you need to carve out three minutes and watch the entire video.
