Don’t be baffled by how scientists show the transformation of wolf – from wild beast to an adorable, friendly canine companion. Because, a new study, headed by Takefumi Kikusui of the Department of Animal Science and Biotechnology at Azabu University in Japan, puts forward a new theory that dogs and homo sapiens progressed together and became ‘buddies’ over the centuries through the mutual eye contact and the higher level of oxytocin (sometimes known as “love hormone”). This, in turn, cultivated the faith and emotion between the two.

It is noteworthy that previous researches suggested that a similar behavior in mother and her child leads to long lasting love and protection. When a mother locks gaze with her baby, it stimulates production of oxytocin, resulting in an outflow of love, strong bond and a sense of protection.

The study, published in the US journal Science, unveiled  that, “Dogs are more skillful than wolves and chimpanzees, the closest respective relatives of dogs and humans, at using human social communicative behaviors.”

The group of researchers observed 30 dog owners communicate with their canine pals for half an hour, and then measured the oxytoxin levels in dogs and their owners, revealed the first part of the study.

The second part focused more on finding out whether the oxytocin actually led to the prolonged stare. The researchers administered oxytocin to a new pack of dogs, and then observed how they communicated with their owners. On a strange note, oxytocin administered to female dogs drew higher levels in both the dogs and their owners when compared with male dogs. However, researchers failed to prove why this happened.

In a nutshell, this interesting research implies that over time as we tamed dogs, they might have evolved with a mutually benign ability to connect with humans exactly the same way that we bond with each other.

Hormone Oxytocin In Dogs, Is Responsible for Sensitivity which Makes them Man’s Best Friend

London, September 20, 2017: Ever wondered why some dogs are so friendly with their owners? It’s because of an association with genetic variations in sensitivity for the hormone Oxytocin, reveals a new study.

Since their domestication from their wild ancestor the wolf to the pets we have today, dogs have developed a unique ability to work together with humans.

One aspect of this is their willingness to “ask for help” when faced with a problem that seems to be too difficult.

However, there are large differences in the willingness to ask for help and to collaborate with humans, between breeds and between dogs of the same breed, according to the researchers.

This ability is associated with variations in sensitivity for the hormone oxytocin — known to play a role in social relationships between individuals.

The effect of oxytocin depends on the function of the structure that it binds to, the receptor, in the cell, the researchers said.

“Oxytocin is extremely important in the social interactions between people. And we also have similar variations in genes in this hormone system,” said Per Jensen, Professor at the Linkoping University, Sweden.

“Studying dog behaviour can help us understand ourselves, and may in the long term contribute to knowledge about various disturbances in social functioning,” Jensen added.

For the study, published in the journal Hormones and Behavior, the team examined 60 golden retrievers whose levels of oxytocin in the blood was increased by spraying the hormone into their nose.

The results showed that some dogs with a particular genetic variant are more sensitive to the hormone oxytocin, making them more likely to seek help from their owners.

These results help us understand how dogs have changed during the process of domestication.

Analysing DNA from 21 wolves, the researchers found the same genetic variation among them.

This suggests that the genetic variation was already present when domestication of the dogs started 15,000 years ago.

  • The symbol is a representation of the relationship that exists between the God, its various manifestations as well as humans 
  • A prayer ceremony took place recently where the Baha’i community of Cambodia gathered to witness their first House of Worship/ Baha’i Temple in the local area

Battambang, August 23, 2017: A small community of Baha’i people gathered in a local temple in Battambang city of Cambodia. The community had gathered to celebrate their first local temple with a holy Baha’i symbol.

On August 20, the Baha’i temple in Battambang had installed a sacred Baha’i symbol on the apex of its dome. The symbol, known as the Greatest Name, was raised as high as 11.8 meters from the ground.

The Greatest Name was drawn by Mishkin Qalam. It symbolizes the relationship between the God and fellow humans. An important milestone was marked as the symbol was installed in the temple.

From the Arabian Caligraphy comes the Greatest Name which comes from “Baha” or glory. The two identical stars in the symbol represent Baha’u’llah and Bab while the vertical line is a symbol of God diverging into various manifestations including human.

The Baha’i community witnessed this installation of the sacred symbol and offered prayers and devotions during the ceremony.

From the Shrine of Baha’u’llah’s sanctuary, the holy dust has been collected and stored in an ornamental box which Shoghi Effendi originally purchased. This box will reside within the campus of the House of Worship and will denote the pure bond between the Centre of Baha’i faith and the local temple.

The Baha’i Temple is also called the House of Worship. The Battambang House of Worship is planned to be inaugurated on the 1st September of this year. This House of Worship, which is the first in the local area, implies a new era of recognition and development for the Baha’i community.

Science is now closer than ever to Pig-Human Organ Transplants

The experiments stem from the fact that humans share a lot of DNA with mammals

Pig-Human Organ Transplant will soon become an essential reality. VOA

August 12, 2017: There’s a word that everybody should learn because in a few years it may be in almost every day use, as scientists come closer to the Pig-Humans Organ Transplants.

According to scientists at Harvard University, advances in research of xenotransplantation, or transplantation of animal organs to humans, promises to bridge the huge gap between the number of human organs available for transplants and the number of patients on waiting lists.

The experiments stem from the fact that humans share a lot of DNA with mammals, specifically pigs. Pig heart valves are already being routinely transplanted into humans, some diabetes patients have transplanted pig pancreas cells and pig skin is often used for treating patients with severe burns.

Combining gene editing technique called CRISPR with cloning, Harvard scientists created piglets that do not harbor viruses harmful to humans. This, they say, may lead to the first direct xenotransplantation within as little as two years.

Such patients would still be required to take anti-rejection drugs so the ultimate goal is to grow pigs with human ready organs that don’t require any medication.

Other scientists express skepticism saying a lot more research is needed before xenotransplantation becomes widely available.
