The first steps have been taken to induce artificial hibernation

You’ve all seen science fiction movies where the crew of a space shuttle, in order to make journeys lasting decades or even longer, are put into special capsules in which a state of hibernation is induced. Obviously, here also comes the question of stopping the effects of aging, because hibernation clearly will not preserve youth and beauty forever.

As for hibernation, even if some more enthusiastic researchers, in other words, talked about its existence in our evolutionary relatives, the Neanderthals, it is clearly not an attribute of Homo sapiens. Rest assured, Neanderthals didn’t either, a fact that can easily be proven by the simple existence of seasonal hunting camps. This is only if there is no sane researcher who can explain to us that Neanderthals hunted in winter in a state of somnambulism. Finally.

The idea is that a group of researchers from Washington University in St. Louis. Louis, USA, managed to induce controlled hibernation in laboratory mice using ultrasound. According to a study published in the journal Nature Metabolism, they stimulated the preoptic area of ​​the hypothalamus of guinea pigs with ultrasound pulses.

The effect was almost instantaneous. After about 10 seconds, the mice recorded a decrease in heart activity, their body temperature dropped, and they entered the sleep phase. The researchers also created a device that activated ultrasound whenever the guinea pigs’ temperature rose above 34 degrees Celsius. Thus, sleep was induced even for 24 hours without interruption, which significantly exceeds the normal sleep schedule of such an animal.

Since the method is non-invasive and has been proven to have no side effects, it has also been tested on humans. And the results, according to the authors of the study, are promising. It is also true that the learning is just beginning. But, obviously, we are talking about the destruction of the barrier, which until now kept everything on the SF border.

What was the greatest danger to prehistoric people

Sometimes you are amazed at what some people can write in what they call reports or scientific studies. This also applies here, where a group of researchers from Ohio State University presents us with a great discovery. Paleolithic and even Neolithic people were beset by great dangers that you would never have imagined. I will explain what the authors wanted to say with their work.

Perhaps discovering for the first time what it means to do prehistoric archaeology, or even experimental archaeology, they realized that you will inevitably cut your fingers when digging stone artifacts out of sediment. I don’t even mention when I talk about experimental archaeology, how do you take care of yourself after trying to create stone tools modeled after Paleolithic tools. Something like a fight with a hysterical cat.

Thus, they concluded that injuries sustained during the creation of weapons and tools were common in ancient times. Moreover, they could then become infected and endanger people’s lives, you don’t even know how they, poor people, survived in such a miserable condition. This strange information was published in American Antiquity, and we have to admit that it can confuse you with the amount of it. That is, prehistoric people who fought mano-a-mano with a cave bear or knocked down a steppe bison with two well-hitting hooks, could die on the head when they were making stone tools at the mouth of the cave.

The fact that medicinal plants have been used for at least 200,000 years and that these people knew their effects very well is already a proven fact, and why not, it may be a sign that the authors of the study are seriously hitting the plains. They did not get infected on their heads either, because otherwise humanity would not have lived to this day forever and ever. Or, who knows, maybe Ohio researchers have actually discovered the mysterious cause of the Neanderthal extinction that no one has been able to answer for over 150 years. They hit stones through their fingers. Look, you wouldn’t expect it.

Where is it healthier to live, in the city center or on the outskirts?

If you were planning to move and you don’t know where exactly, namely in the center or in the suburbs, or even in the countryside, you have come to the right address, because we will explain it to you. Actually, not us, but an international team of specialists from the USA, Sweden and Denmark, the team that wrote a study about this, which they published in Science Advances.

People analyzed not only the architecture, urban plans of different areas, but also the mental state of the people who lived there, depending on the area where they lived. It turned out that the central areas of cities, when they are also green, are an ideal place for people to move. It not only creates a welcoming crowd to socialize with, but also provides you with places to do so (theatres, cinemas, shops, bars, discos, restaurants, etc.).

It’s true that these things can be a little depressing if there’s too much crowding, and here we mean primarily buildings and a lack of green space. But overall, the fact that it gives you lots of opportunities to socialize is good for your mental health. The same cannot be said about the suburbs, where the density of buildings and the population are also lower, as well as opportunities for communication.

However, if you like to be more secluded, have your own garden, then this is the perfect place. In conclusion, we cannot fool this study. A new fact that the researchers found is that the risk of depression, contrary to expectations, is higher in the suburbs and rural areas than in crowded city centers. The rest is up to you to decide what will be better for you.
