Scientists have found love genes

A large-scale genetic study, involving more than 190 researchers from 140 centers, found gene variants related to human happiness and other mental states.

According to Medical News Today, this is one of the largest studies ever published about the genes involved in human behavior.

According to research published in Nature, researchers analyzed genetic data of hundreds of thousands of different people. Since then they have discovered the gene variant e related to three basic human mental states: happiness, depression and neurological disorders.

"Heaven endowed" love life

One of the researchers, Alexis Frazier-Wood, an assistant professor of pediatrics and nutrition at Baylor School of Medicine in Houston, USA, explains more clearly: " We have found three related gene variants. to the feeling of happiness in each person, it indicates how happy they feel about life. "

The team also found that gene variants are primarily expressed in the central nervous system, adrenal tissues and pancreas.

However, although the latest research results will help people somewhat understand the emotional trends of each individual, experts still warn that genes are not the dominant factor in the way people think. or the feeling of their life. In other words, the gene does not determine the whole story of one's happiness.

According to the research team, the environmental factors and how they affect human genes are also important aspects.

However, genetic research can help us start to understand why some people seem to have been " blessed " (with the gene available to regulate this trait) for emotional propensity to shape. these characteristics in life. Perhaps so, sometimes we see that in life there are people who are always very positive and optimistic, no matter how difficult the circumstances are.

Researchers also hope these new findings will help clarify the picture of the cause of differences in the experience of happiness. They argue that these landmark discoveries are only really beginning and that gene variants have found only a small fraction of the mysteries of the human genome that are still awaiting discovery.

Born "old" face available

Meanwhile, a new study published in Current Biology reports that scientists have found a particular gene that makes its owner appear to be about 2 years older than their actual age.

According to the Washington Post, one of the co-authors of the study, Manfred Kayser said this is the first time "finding a gene helps explain partly why some people look older or younger than their real age ".

The conclusion was made by researchers after taking into account the impact of all the familiar factors that often affect the appearance of a person like smoking, sun exposure, age, gender, wrinkles .

Gene is not the dominant factor in how people think or feel about their lives.

Specifically, the team looked at nearly 2,700 Dutch adults who looked older than their actual age. They show photos of these people to others and ask to guess the age of the people in the picture.

Along with that, the team analyzed the genome of the participants, considering a total of about 8 million gene variants.

They found that a gene variant is clearly linked to a slightly older appearance than the actual age of those with the gene. The research team reaffirmed this result when considering the genome and appearance of participants in two other studies.

A special gene called MC1R , which is involved in the synthesis of melanin in the skin, people with more melanin often have darker skin.

The variants in the gene are also related to pale skin and red hair. However, because new research does not find a link between human skin color and their appearance, it is possible that the gene variant will also affect the appearance of people in other ways.

The researchers also note that this is just a gene variant related to the appearance of older people. It is possible that many other genes are also involved in this fact.
