Science does not stand still but is developing rapidly. This is good news: in just the last 5 years, scientists have made so many breakthroughs in different areas of life that we can only open our mouths in surprise! We’ll talk about these things.
Heart on a 3D printer
3D printers have surprised people more than once. And now they're doing it again. In 2019, scientists managed to create a real living heart with its help!
For this, human fat cells are taken, which are converted into stem cells. Then the extracted material is mixed with connective tissue. It makes something like ink for a printer. On it, scientists in advance build the organ that they should get.
Printing the sample took 3.5 hours. And in order to get a full-fledged human heart with all the vessels, you need more cells and" ink", and the printing itself should take about a day.
Perhaps in the next 10 years, this technology will be available in many medical institutions - because it is cheap and easy!
Photo of a black hole
A historic discovery that was also made in 2019: the first time people got a picture of a black hole!
It itself is located at a distance of 53 million light-years from Earth. This was achieved by combining 8 telescopes, which observed not only this object but also for another black hole, which is closer to us.
The first results were obtained by scientists already in 2017, but it took them two years to process them further. As a result, we got the first detailed image of a black hole, which should help scientists in their further study of these objects.
The problem of human organ transplantation still remains urgent. Some people die only because they did not have time to wait for their turn for this procedure.
But a group of scientists from Harvard seems to have solved this problem by learning how to artificially grow organs. True, with the help of animals (for example, pigs), from which they get the necessary cells.
They also learned to remove the necessary organ from the animal, followed by washing to such an extent that only tissue remains of it.
Then, human stem cells are planted on it, which come into contact with each other, generating a new organ. And after its final formation, it can be transplanted to a person. Despite the different DNAs, it survives well in the human body.
The oldest discovery from today. We all remember how one day the Ebola virus began to take the lives of hundreds of people. And scientists had no right to leave it just like that.
The drug itself was developed following the example of a similar smallpox vaccine. Its main action is to build protection around the body of an uninfected person.
The first vaccines were started in 2015 in Guinea. More than 4 thousand people turned to doctors voluntarily, who somehow came into contact with people who were exposed to the terrible virus.
The indicators after vaccination delighted scientists: 10 days after vaccination, no one was ill. 3 months after the start of vaccination, scientists have proven the absolute effectiveness of the drug they developed.
Embryo DNA Revision
Scientists managed to do the unimaginable last year, 2018. A team of biologists from Pennsylvania was able to reconstruct a piece of DNA from an embryo.
However, so far this experiment was conducted only on laboratory mice, but the successful result already gives hope that the technology will be able to be applied to people. According to the scientists themselves, they are now thinking about how best to transfer its use to a pregnant woman.
If everything goes well, then the various forms of hereditary diseases detected in the fetus can be corrected directly in the womb. Plus, this technology will reduce the number of miscarriages in women!
