"Space salad" is also as tasty and useful as ground salad, research

Florida: Research on salad leaves grown in space has shown that in terms of their taste and nutrition, they are similar to ground salad leaves, but in some cases even better than ground salad leaves.The addresses of the salads mentioned here were developed between 2014 and 2016, in a special system "Vegetable Production System" at the World Space Station.The system uses LED lights and automatic irrigation systems to grow vegetables, which do not require human intervention or maintenance.The staff at the space station ate some of these salad leaves and described them as just as delicious as ground salad.The remaining salad leaves were frozen and shipped back to the ground. Here is a careful and detailed biological and chemical comparison of the "ground salad leaves" grown during the same period at the Kennedy Space Center, Florida.A report published in the research journal "Frontiers in Plant Science" states that space salads are similar to those grown on Earth in terms of their biochemical and chemical composition (chemical and biological composition).However, it is more potent than ground salad in terms of useful minerals, especially potassium, sodium, phosphorus, sulfur and zinc. In addition, it also contains high amounts of useful compounds called "phenolics", which are known for their beneficial properties against viruses, inflammation and cancer.Another important thing is that space salads do not contain harmful germs such as E. coli or salmonella, which usually cause poisoning (food poisoning) and take the eater to the hospital.This is the first time that food grown in space has been described as useful and healthy for human consumption. In the next phase, similar trials will be performed on other fruits, tomatoes and peppers.

The singer, musician and poet robot released their debut album

Georgia: Shimon, a robot recently made worldwide, has now released a new album of his own songs, which he will visit in several countries.The robot is named Shimon, which first debuted in 2017 and does all its work in artificial intelligence and deep learning. It can write songs based on its ability, set music lyrics, and even sing. Now the most important thing is that the robot will release his debut album soon.It was developed three years ago by the Georgia Institute of Technology specialists and at that time it could only play Morumba, a musical instrument like the Xylophone. He trained for artificial intelligence and deep learning for music.But this robot continued to learn as a human being and in the meantime read a total of five million songs and increased its knowledge. Now this robot can write its own songs, make melodies, and adjust their music automatically. The robot will release a new album soon.You can listen to his first song "Into Your Mind" here, but sorry, this song seems to be swinging somewhere.When Simon is in robot mode, he also dances. The robot will travel all over the world to advertise his edited lyrics and songs, and his first album includes 8 to 10 songs. The interesting thing is that humans give him a topic and thus he starts to sing on it, for example, when someone says space or says a cloud, Simon starts looking for a song.Experts have listened to over five million songs and their lyrics to Simon and he finds them in his memory and links them with artificial intelligence. The robot then writes his song with his words and composes his lyrics. This robot can compose melodies of all kinds and harmonies such as jazz, rock and blue. Thanks to Deep Learning, it explains the interrelationship of lyrics, rhythms and lyrics.

Imagery based on billions of pixels in Mars

PASADINA, California - NASA's Jet Propulsion Laboratory has released an amazingly detailed picture of the surface of the red planet Mars. After taking 1000 images around Mars for four consecutive days, they have been meticulously added and a 1.8 billion pixel panorama is created that provides a very detailed view.The spacecraft sent to Mars is slowly moving on Mars and is increasing our knowledge through our scientific experiments. Curiosity has to take regular pictures of each aspect of the image in order to keep it consistent throughout the day and in this way, 1000 images were taken in four days which were combined to create a full circle in the form of a circle.For the first time the spacecraft has released this detailed image, it can be seen in the area named Glenn Torriden, which is named after one of Scotland and NASA's Jet Propulsion Laboratory, Ashwin Wassoda, head of the curiosity project, said. This area is full of hematite mites.Curiosity has also excavated at this location and sampled clays to confirm or deny the organic compounds contained in them. Other important research is also collecting information about the main surface of the galley crater. Experts believe that the water may have been in the pit sometimes and some of its artifacts may still be found.After such important photos Kerosti is on its second mission. A hill is heading toward Mount Sharp and will conduct further research there.

Successful eco-friendly and flexible cement experience.

Australia: We know that cement making is not an environmentally friendly process and yet it is flexible despite its robustness. But now Australian experts have developed a highly eco-friendly and resilient cement that can be very effective in disasters and earthquakes.Experts at Swinburne University in Australia have developed an eco-friendly concrete that does not require traditional cement to make and retains its elasticity even after drying.Although concrete can be weighed down, it is immediately prone to breakage when its load is placed at its center. The reason is that despite all its hardness, it is flexible.On the other hand, construction of seismic terrain is made more flexible by a special building code which costs a lot. The new cement that Swinburne University has created requires less energy and less carbon dioxide in its preparation.Cement is used to produce very high temperatures which cause carbon dioxide emissions. But experts say the new cement is manufactured from industrial waste such as flying carbon in coal plants and other materials. It is a type of geopolymer compost that can also be prepared at normal temperatures.Although flexible cement is being researched worldwide, cement manufactured in Australia requires 36% less energy and 76% less carbon dioxide. Behzad Niamatullah, a research scientist, says that the concrete made from this cement has been viewed 400 times more flexible than others.As concrete begins to break down, the fibers of the polymer do not allow it to scatter. For this reason, the concrete can be used to build buildings in countries including Japan and Pakistan, where the risk of earthquakes remains high. The whole of this cement has been published in the Rawdad Journal of Construction and Building Material.

A Chinese spacecraft discovered a 40-foot-deep layer of sand on the moon

The spacecraft is part of "Uto2" "Chinese Mission to the Moon" Chang E4.Beijing: With the help of an automated mission sent to the dark side of the moon, Chinese scientists have discovered a thick layer of sand, up to 40 feet deep, in a large pit there. Until now, we believed that the moon is a rocky surface, with a little sand scattered on the surface, but last year, the latest discovery of the "Rover" UVO 2 revealed that the moon. There may be more sand on the moon than we had previously expected.Keep in mind that the spacecraft is part of the "Uto2" Chinese mission to the moon "Chang E4" while it is also the first dynamic human-powered machine to land on the Moon's dark side. The "dark side of the moon" refers to the part of the moon that is always on the opposite side of the earth and is not visible to us.The vehicle is equipped with special devices for close observation of the moon, including a high frequency radar that can peek hundreds of feet deep, within the rocky surface of the moon.Through this radar, Chinese experts have been exploring the inner part of the moon for the past one year, which is closer to the surface, at lower depths. The same research showed that the sand at the moon's surface is much higher than we expected.It will be interesting to read that the sand on the moon is more finer than the sand found on the ground beaches and in the deserts.Experts agree that the sand is one of the remnants of shabby collisions that took place billions of years ago, which saw large rocks of the moon crumble into fine form.Scientists say that when the earth and the moon were new, it was raining on both of them at that time. Over time, virtually all remnants of Shahab Saqib disappeared as a result of water, wind and other natural factors on the earth, but there was nothing like it on the moon. Because of this, the moon's surface has been around for the last three or three and a half billion years.Humans plan that in the near or distant future, they will settle on the moon ... And in order to plan these settlements we must know where the strong and smooth rocks are located on the surface of the moon; how is the sand, How much area is spread over and how deep it is, etc.In addition to all this, by further research on sand at the surface of the moon, we will be able to better understand our early periods and evolution of the earth and solar system, in addition to the moon.Details of this discovery have been published online in the latest issue of the research journal "Science Advances."

Discover another moon of the earth but size as small as car

Discover another moon of the earth but size as small as car.A small honeycomb has become a partial moon of the earth by being tied to the earth's artificial bondage, the actual picture of the moon is prominent in the picture.A small honeycomb has become a partial moon of the earth by being tied to the earth's artificial bondage, the actual picture of the moon is prominent in the picture.Arizona: Probably another small moon on Earth, but it's brand new and has been spinning around the Earth regularly.During the Catalina Sky Survey in Arizona, the first experts saw a celestial stone that was very dim and moving faster than other objects in the sky. Over the next few days, observatories located on different parts of the earth watched it carefully.It was named the 2020 CD Three and its orbit and rotation were detected and it was found that through the rooftop, it was tied to the ground and has been rotating around the earth for the last three years but its orbit is very elliptical. Is.The Minor Planet Center, which monitors small objects in space, has researched it and announced its discovery. According to the company, it is not an artificial commodity, but a small honeymoon (asteroid), which has become an attraction for the rotating earth and is rotating around the earth.Small partial moonThis is the second Shahabiya that revolves in orbit around the earth. Earlier, another crime, the 2006 RH120, was floating around the earth. But after being a prisoner of land from September 2006 to June 2007, he went away free from gravity.By careful estimation the size of the new moon is very small, maybe two to three and a half meters long, the size of a car. In this sense it is not equal to the beautiful moon of the earth and completes a cycle around our Earth in 47 days. The orbit is beyond our own moon.Astronomers insist that its orbit is not stable, and it will soon move away from Earth. In April, it is not expected to be part of the Earth Gravity.
