Usually, when people are provided with accommodation, they go down in search of food. Likewise, with space being built in space, astronomers, technicians, and filmmakers have been on the hunt for food.

Actor Matt Damon cultivates potatoes on Mars for survival in the world-renowned science fiction film 'The Martian'. Many people have seen it and thought, how will the potato taste? A group of scientists from the Netherlands has tried to answer this question. They cultivated vegetables on Mars.

A group of researchers at Wageningen University has announced that the vegetables and vegetables they have grown on Mars for the past 2 years are safe and useful for human consumption. Scientists have created artificial red soil by placing the material in imitation of the soil of Mars.

There are enough radishes, pulses, grains, and tomatoes. There are also some types of vegetables. The taste test of these vegetables will begin by testing the taste and comparing the differences with earth soil. To be done Researchers are very optimistic about the matter. Many astronomers and technologists around the world want to build human settlements on Mars by 2021. Among them is Elon Musk, chief executive of Space-X. He said that the mission of human well-being will be more beneficial in this study.

Despite many efforts in our country, the use of plastic could not be stopped. Behind this, there is more to our financial gain than bad habits. The business class continues to do so in the hope of making a profit, and the common people prefer it for the convenience of low cost and frequent use.

 As a result, the plastic bags attached to the handles are removed, but the use of plastic bags without handles has increased manifold! As a result, the pollution levels in the environment have increased manifold.

 The use of plastic is increasing. The government does not have the same vision as environmentalists. If only one-tenth of the noise coming from the Sundarbans was for plastic, the atmosphere around us would have been better.

 In the developed world, the use of such plastic is very rare. They are manufactured in accordance with certain standards and are also used in some places. Even then, they want to use plastic to bring it to the zero levels. At the same time, the prevention of waste caused by plastic packets is also a goal.

 Therefore, American scientists have used plastic substitutes, especially in the case of food packets, and plastic products made with milk material to prevent food waste due to plastic, which looks exactly like plastic but is very healthy and worth eating!

 Yes, you are right that you can eat this packet. It's protein-free. As a result, there is no alternative to prevent food waste. Because when you pack packets of cheese, butter or such foods with plastic or any other ingredient, the packet is wasted in a lot of food. And if you can eat the whole packet with food, there is no possibility of wastage. At the same time, it will protect the environment. Besides, ordinary paper can be saved. Because if you want you can use it as a T-bag as well so the whole T-bag will be turned into tea. Only tea leaves will remain.

 In the same way, plastic can be an excellent alternative as a packet of soups or other food packets. As it protects the environment, on the one hand, it saves food three times better than plastic. It is very effective in preventing oxygen or air. As a result, it keeps the food good in the long run by keeping the air away from the food.

Therefore, if used extensively, it can be eliminated from the environment as harmful materials like plastic which can protect the tree as an alternative to paper. At the same time, foodstuffs will be safer than ever. Several researchers from the US Department of Agriculture Researchers conducted the study. They are working on what needs to be done to make the most of it. If its production costs can be reduced comparatively and its production process can be simplified, that could be great news for the future world.

Be it reading or drawing or writing or expressing something, none of us can shake the importance of pencil. The importance of a pencil in human history is immense. Here's how your modern pencil was born today:

It has been said in England since the beginning of the pencil. Graphite was slowly dissipating from the Bourdel coal mine. Britain came to war with France in the 5th. But then it was time for Napoleon. Only if you win the war will the whole world change. But the pencil industry began to decline. At the very end of the war, England imposed a burden on France. That is to import pencils from France to England and England to be the main market in that market. Although it was introduced to meet some of the military's needs, some of the worst aspects of England's trade appear. France suddenly suffers from a pencil and graphite crisis.

At that time, France's wartime minister Lazare Carno asked the responsible scientist and commander of the military, Nicola Jacques Kout, to do something about the matter.
At that time Kotz was involved in the study of a balloon made for the military. For this study, he had to lose his left eye in an explosion. With the exception of balloon research, Kot now focuses on the problem of pencil and graphite. That is, he has to solve a problem so that France can get rid of the problem of graphite and pencil.

The material that solves this problem is the graphite and clay obtained from the soil. He mixed the two ingredients with water and made a mixer and heated them in the fire. He was surprised to find that he could control the color of the mixer himself. It depends on how much clay he is using. He then studied how a pencil ink could be darkened or lightened with a mixture of soft graphite.

The pencil that was discovered by Kot was taken in 5 patents. In England, when the pencil was going crazy, the makers considered the pencil formula as a model.

People of the present age owe it to them. If he had not discovered, people of today would not have pencils for writing or other work.

Fossils are fossils, which, in time, are laminated and shaped like stones. Various fossils may exist, but this time scientists have discovered a fossil in Canada that may be the oldest fossil in microbial biodiversity. Its age is estimated by scientists to be between 1.6 billion and 1.25 billion years old. Although scientists are still conducting various studies, they have really found the most ancient microbial fossils.

In fact, if this microcosm is the earliest microbial life on earth, scientists speculate that it was not too late to develop life after the formation of the earth.

"All we can say is that life began to evolve very quickly after the Earth's terrain and seas formed 1.5 billion years ago. This means that the evolution of organisms is not very difficult if we get the right environment and the right ingredients for survival, "- said Matthew Dodd. He is a graduate of the Department of Biogeochemistry at University College London. He is also one of the major contributors to the study.

Controversial History:

There is no doubt that 1.5 billion years ago, the initial development of life was greater in water bodies. But the most debated issue is when the first life was developed. Scientists have discovered chemicals about 1.5 billion years ago from zircon found in Australia. In Australia, a type of filamentous national algae has been found that is 1.5 billion years old. Also found in Greenland, cyan bacteria were found 1.5 billion years ago. Then it appears that the life of the plant originated before the organism. However, scientists are still unable to say exactly when the first and the first development took place.

The main problem for scientists knows exactly when the evolution of small organisms took place, but during that time the earth was passing through various structural conditions.

For example, a stone has been found in Australia that is around 1.5 billion years old. It's called Apex Shirt. Some small microfossil particles are seen in the middle of it. Scientist Rothschild said
“Such fused particles or fossils are found in Calavadera but they are not very new. The question is, what can be said about them in a very final way? This is the source of the oldest life. ”

Let's see if this new acquisition of scientists solves this mystery!

Geologists have discovered more than 3 footprints of primitive humans dating back to 4,000-5,000 years, on the shores of Lake Natron in the village of Engaro Cerro, nine miles from the volcanic volcano in southern Tanzania, Africa.

They were covered mainly because of volcanic ash and clay. Researchers say that the impression was made when humans walked the earth in the wake of modern human civilization. As for the thousand years old impression here, some of the impressions are 3 thousand years old.

Those thousand years mean it's a strange time. Physiologically, modern people (homo sapiens) have become, at this very moment, or even a little earlier, the modern creative man (homo sapiens). This is the ultimate turning point in becoming human beings. Getting the footprints right at that time is like getting a 'gold mine' to scientists. The story of the beginnings of the modern man is hidden here! In Africa, there is no such footprint of Homo sapiens anywhere else in the world.

The research team was led by a National Geographic grantee Appalachian State University geologist. Cynthia Leutkus Pierce. Dr. Pierce told The Mail Online, "Footprints were made about 3,000 and 4,000 years ago." This means that these footprints are the latest sign of the Pleistocene era.

These footprints in the village of Nigro Cerro have added a unique record to fossil footprint sites around the world. This will give us an idea of the activity and behavior of our ancestors of the Pleistocene era.

Also, the research team is identifying at least 20 tracks, which prove that some of the footprints have resulted from people's jogging. The footprints also show evidence of more than 12 people traveling together.

Although some of the footprints were discovered more than ten years ago by a local villager, it was the first time an American conservationist visited the area that it had caught the attention of the scientific community in the 21st.

Researchers are now looking for ways to preserve the space long-term. Although the 3D picture of each footprint will also serve as a useful backup. Researchers believe there are probably more footprints under the shoulders.

Human beings are the best creatures of creation. People talk to each other, exchange ideas. Animals exchanged emotions, but they were not known to use any language. However, a new study has recently emerged.

Scientists have seen two dolphins talking among themselves or swearing like humans. And the news has stirred the world. Sky News reported the news.

Scientists have come to this conclusion by observing the conduct of two bottlenose dolphins called Ukraine's Yasha and Yana. Scientists have observed that dolphins interact with one another through two gestures and whistles, and when one of them says 'talk', the other listens to it and then answers his own.

And the whole conversation has to be done in its own way. The researchers did not induce or train them in any of these behaviors.

Head of the research team said. According to Ryabov, 'a distinct and autonomous language has emerged in the conduct of dolphins. They have been able to form complete sentences through their heads and gestures, which are not observed in other organisms. '

Even when in the water, dolphins are but essentially mammals. Scientists have assumed that their intelligence is very advanced along the way. But the researchers were able to catch the swear words that they were using. However, it was not possible for the dolphins to read any of the languages.

No one got one hundred in the mark sheet. He doesn't have what formal education means. NASA does not even pay him a large salary because the college boundary certificate is not in his hands.

Fewer incomes have to be measured. Even at the age of 16, he still had to come to Rose at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California Eight-hour duty, half-hour lunch break. He had to punch in and out of NASA's Identity card given by Rose during the trip to Jepil. If not, you can cut it! Yes, even at the age of 16. Overtime is paid even though the pay is low.

She is Susan Finley. NASA is looking to conquer Jupiter, the largest and most dangerous planet in the solar system. It was the responsibility of seeing; hearing and understanding the first signal that the spacecraft Juno sent after the first human civilization had reached the orbit of Jupiter in Indian orbit on Tuesday morning. Juno was asked from NASA's control room, 'Are you good? Have you reached Isn't it difficult to get in the way? 'Jupiter's distance from the earth is no less! So the message sent to us will go to Juno and decode it and it will take time for Juno's counter-message to reach us. It was. When we were measuring second-minute in excitement, at that time, Juno's signal arrived at us this morning - 'Okay. Well arrived No delay, no hassle. ”But not everyone has the skills to properly understand that signal.

At least NASA has no one else at the time except this Finley, who is 8 years old. Therefore, Finlay was given the responsibility of overseeing the Juno mission. The finale also decoded signals sent by two Rover spacecraft to Mars on April 28. The first message was sent to Finley by the curiosity of Mars on the 222nd. NASA will also have the responsibility of listening to the news of another Rover spacecraft that will be sent to Mars in 2021 if it survives. Susan Finley said, "I have been in space research before NASA. At 5, I came first to JPL. NASA was not born yet. I worked as an assistant in computer engineering. Soon after that, the United States launched its first satellite, the Explorer-One. Six months later, in the US Congress, NASA decided. My two children, I left NASA for six months to do the little hands and feet of the children. Come back to 3. I went to college to get an engineering degree. However, I could not finish reading for my children's education. I don't have a degree. So the pay is less. NASA overpowered me with overtime, however. You still have to punch the card and stay for eight hours. It just takes honor! What to do, there is no degree that I have! "

Not having a degree, maybe Lakshmi is lacking in Finley's house! However, it was through the finals that NASA reached Jupiter to reach Lakshmilav. The gurus of civilization conquered Jupiter almost by the hands of infinite growth! This is fresh in the twenty-first century.

Oxygen is declining rapidly from Earth, scientists have pointed out in a recent study. Although there is nothing to panic about now, this is terrible news for the future world. Because some days can be spent without water, it is possible to live for a few days without food, but without oxygen, animal civilization will be destroyed immediately.

 A group of scientists at Princeton University in New Jersey, USA, have come to the conclusion that oxygen is reduced by conducting a study. Scientists observe that in the last 1 million years, 1.5 percent of the oxygen has disappeared from the Earth's atmosphere. The amount of which is not too much, but scientists are thinking more and more that this is the maximum in the last one hundred years. 1.5 percent. That is the highest rate of oxygen depletion in the last 5 years.

 Scientists do not give a specific reason for this, but scientists believe that in the last 5 years, a large amount of fossil fuel has been used in the world. As a result, carbon dioxide has become very high. And this may be one of the major reasons for the decline in oxygen.

 Scientists collect bubbles from the ice that has been frozen in Greenland and Antarctica for thousands of years. Later they collected and tested the oxygen within it. However, they were only interested in the experiment, scientists said. They would later conclude that the level of oxygen in the Earth's atmosphere is much lower than it was millions of years ago. At present, oxygen levels are around 20 percent. Scientists observe more, low oxygen levels do not mean that the amount of carbon dioxide has increased in the atmosphere.

Scientists have come up with one more reason as to why oxygen is reduced. It is a long-term natural process of exposure to seawater.
A scientific team member said. Higgins said that as global warming warms the seawater, it will be able to absorb more oxygen. On the contrary, the colder the water, the more it will be able to absorb the gas.

He added that if the history of oxygen is seen in the earth, then it can be seen that the matter is intimately associated with complex living. Scientists point out that the complex life-cycle process may be involved in the reduction of oxygen, although in part.
