Our brains are almost 4 times larger than they were 6 million years ago. However, about 100,000 years ago, our brains began to shrink in size. The reason for this was thought to be a change in diet or the shrinking of our entire body. A new idea was that sociability reduces the workload of the brain.
You might say, “What’s wrong with ants, we’re not genetically close” because we’re not. However, these creatures also lead a very social life. Ants that establish large, complex and homogeneous communities; They lead a communal life by acquiring different assignments.
When the researchers examined the ant brain in terms of structure, size, and energy use, they realized that their social lives saved them a great deal of energy. Mentioning that people’s collective intelligence has gradually improved after they have adapted to living together, like ants, which work much more efficiently in groups, scientists think that the size of the brain may have shrunk due to this lowering the energy need in the brain.
Living in large groups in constant interaction eliminates the need to collect all the information necessary for survival in a single member. A community with knowledge distribution reduces the mental burden by communicating this information to each other like a network. The authors of the study explain the situation as follows: “If group decision-making ability creates coherent group responses that will increase cognitive accuracy and speed in making individual decisions, considering that the decisions taken and the energy expended in this way are also related to survival success; The human brain may also have shrunk over time to conserve metabolic energy.”
Remains of ancient microorganisms were found in a ruby formed in the earth’s crust 2.5 billion years ago. These ruins contain evidence of ancient life.
Issues such as how the universe, planets, the Earth were formed, and what is going on in the rest of the universe other than the environment we live in are among the topics that people always wonder about. One of these curious and interesting subjects is who lived in the billions of years of the Earth’s history, and what kind of life existed, especially in the early days of Earth’s history.
Every research and discovery made by scientists excites anyone who has a curiosity about human history. Pure carbon, the remains of ancient microorganisms called graphite, from times before the emergence of multicellular life, was found in a ruby formed in the earth’s crust exactly 2.5 billion years ago by geologists.
Geologist Chris Yakymchuk at the University of Waterloo in Canada and his team found this graphite while investigating Greenland, where one of the world’s oldest known mineral deposits is located. Rubies formed under intense heat and pressure at the Earth’s tectonic borders are full of deep colors made up of the rare element chromium.
“Based on the increased amount of carbon-12 in this graphite, we concluded that carbon atoms were once present in ancient life, most likely dead microorganisms such as cyanobacteria,” Yakymchuk said. gave place.
The COVID-19 vaccine named NARUVAX-C19 (pets) for cats was developed by the International Vaccination Center in Kazakhstan. It has been reported that the vaccine has been tested on cats.
Our animal friends, who are sometimes a source of joy, sometimes close friends, sometimes confidants, and sometimes sweet troubles, have also been affected by the COVID-19 pandemic. Especially the pets, cats and dogs next to us sometimes created anxiety in a different way because their interactions with the virus could not be determined exactly.
In the past years and at the beginning of the pandemic, some studies have stated that animals can also be infected with the COVID-19 virus and may even be carriers, while some studies have suggested that no cases have been found in animals.
According to a study, Feline Infectious Peritonitis (FIP), which occurs as a result of the COVID-19 mutation, was reported to be deadly and contagious for cats, but experts said that animals did not experience virus symptoms like humans and did not experience severe symptoms. Similar concerns can be experienced in every epidemic disease. Therefore, studies are also carried out against the risk of viruses in animals.
One of the studies for animals was carried out in Kazakhstan. A subunit vaccine for cats called NARUVAX-C19 (pets) has been developed by the International Vaccination Center of the National Agricultural Research University. The vaccine was introduced to the public at the International Agriculture Fair held in Nur Sultan.
