You probably don’t know that we inherit these things from our parents too

You probably don't know that we inherit these things from our parents too 92

Do we inherit traits from our parents? Are we picking genes from only one parent, or is there a combination of both parents’ genes?

According to geneticist Don Alain of the Wexner Medical Center at Ohio State University, it’s almost impossible to know who inherited one or the other part of the body or a particular characteristic because, most traits are determined by many different genes rather than only one.

Nevertheless, genetics can tell us something curious about what has already been clarified, just about the issue of DNA inheritance.

Rapid or slow metabolism

There are two types of fat in our body: ‘good’ brown fat, which boosts our metabolism and helps maintain a healthy weight, and ‘bad’ fat, which causes obesity and related diseases.

What do we inherit from our parents?

Everyone has their own characteristics, but the level of brown fat in our body (which means a certain metabolic rate) is most likely derived from the mother.

Weight gain

While the mother’s DNA can help lose weight quickly and maintain good shape, the father gives the genes associated with white fat, which means that there will be a tendency for being overweight.

In this case, not only the subcutaneous white adipose tissue, but also the internal fat, which accumulates in different organs, depends on the paternal genes.

Concentration ability

If the mother had lower levels of serotonin, the “good mood hormone”, her children are likely to develop attention deficit hyperactivity disorder.

It is a fact that the genes responsible for serotonin production are also responsible for the ability to concentrate. This link was discovered by doctors in the 2000s, and an article about it was published in 2010 in the medical journal JAMA Psychiatry.

Early puberty

Almost all children, with rare exceptions when there are clinical abnormalities, go through puberty and many of its not particularly pleasant aspects, such as acne and voice disorders. The genes of the father were found to be responsible for the onset of early puberty.

Doctors learn this when examining several children with early puberty. They entered it at the age of 8-9 years, instead of the usual 11-13 years. It turns out that the special genetic mutation responsible for earlier puberty was inherited by their fathers. The study was published in New England Journal of Medicine.

Wrinkles and gray hair

How good a person’s skin will look with age depends on changes in cellular level that build up over the years and depend on the mitochondrial DNA that is always obtained from the mother.

This can also be influenced by environmental factors such as sun, smoking or unhealthy eating. All this can damage the mitochondrial DNA and therefore affect the appearance.

However, some changes, such as wrinkles on the face, around the lips and eyes, as well as hair graying, depend on the part inherited from the mother, and nothing can be done to prevent it.

The mood

Mothers can influence the mood of their children in many ways, including by setting a strict framework for childhood behavior. But they may inherit the limbic system that controls emotions.

If the mother had a frequent mood change or depression, her daughter would most likely have the same experiences. Researchers have found that this is most often transmitted from mothers to daughters and much less frequently from mothers to sons.

That is, daughters, in most cases, inherit at least the mood of their mothers. This study was published in the journal Neuroscience.

The likelihood of having a boy or a girl

It is believed that the gender of their child depends on the parents themselves. But, there is another factor that determines the gender of the child – siblings have the father in their family.

If the father has more brothers, the probability of having a boy is very high. It’s respectable for the sisters.

Memory

It has long been known that Alzheimer’s disease is often hereditary. A recent study published in the journal Biological Psychiatry, claims that it depends primarily on the mother.

Alzheimer’s disease is the most common cause of dementia in the elderly, so it is very important to know what factors can lead to it.

If the mother has symptoms of Alzheimer’s disease then her children are likely to be ill with it as well.

All they can do to delay the inevitable is to do so-called “brain workouts”.

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

The goal of human civilization is to create AI and disappear? 96

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 99

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 100

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.
