Our scientists have installed different weather stations all over the world so that we can get information about every change in the weather. Like many other things in the world, there are also many things about weather stations that we do not know, and one of them is, “Higher Operating Weather Station.” So do you know about the world’s highest weather station, don’t know, so let’s find out…
Height Of World’s Highest Weather Station
The record of the highest altitude weather station has changed a few days ago, when a team of international researchers installed five automated weather stations on the world’s highest peak, Mount Everest. All these five weather stations are located at a different altitude, including the world’s highest weather station. Out of these five weather stations, the two highest weather stations are installed in Balcony area (8,430 m) and South Col (7,945 m) and remain three stations were installed at Phortse (3,810 m), Everest Base Camp (5,315 m) and Camp II (6,464 m).
The new weather stations are part of the National Geographic Society’s Perpetual Planet Extreme Expedition, which was attended by various explorers from 8 countries, including 17 Nepali researchers. To work on this project, the National Geographic Society has worked in partnership with Tribhuvan University, and the Government of Nepal, to run this two-month program they raised funds from Rolex.
Journey Of Installing The World’s Highest Weather Station
Installing the weather station above the death zone at the height of 27,658 feet (8,430 meters) where it becomes difficult for a person to breathe, is like a nightmare. But the researchers had already realized this situation, they had already been prepared for it. Each component was already built so that it could be installed quickly. Although all people in this team were experts in their fields, but installing a weather station at such a height was probably the first experience and that’s why they did separate practice for erecting the structure of weather station as quickly and efficiently with the team of six Sherpa.
After crossing all the problems, when the team reached the top, they felt that maybe we would soon execute the installation process, but it was probably not so easy because it was so cold there that the batteries for drilling the station in place were dead. The team filled the batteries in their armpits, crosses and other parts of the body to back them up in life. About this, the Baker Perry (Climate scientist and the part of this team) said that “It was an anti-climatic moment just standing there for 45 minutes,” Baker said.
During the installation process, they suddenly realized that the wind sensors they brought were left in the camp. But maybe that was their day and that’s why a solution came out for this problem also, which was a bit weird, about which Baker Perry said, “We had a shovel with us that had an adjustable handle and we looked at the handle and said ‘gosh, we could use this,’” maybe this the high altitude solution. After installing, the world’s highest weather station, the team also install another weather station at South Col at 26,066 (7,945 meters).
According to a report by National Geographic (NG), during this project “the members of this project also collected the highest-ever ice core, completed the highest-elevation helicopter-based lidar scan, expanded the elevation records for high-dwelling species, and documented the history of the mountain’s glaciers.”
Benefits From World’s Highest Weather Station
This world’s highest weather station can prove to be beneficial for us in many ways. It will be helpful for scientists to get some of the first regular, direct observations of the jet stream. It will also provide regular updates on the mysterious Death Zone, which will help scientists to understand the death zone. Due to installed on such a high altitude, this weather station will give information about the situation of the upper sides of Everest, so the researchers and the climbers can be warned before any disaster.
The biggest advantage of putting this weather station at such a height is that it can help in very significant research on climate change. Also, data received from this will become helpful to explore, how Climate Change is affecting our mountains, how fast our glaciers are melting, etc. “Climate change is one of the biggest challenges facing humanity and there is still much to learn about how it’s already altered the world, from the deepest parts of the ocean to its tallest mountains,” Jonathan Baillie, executive vice president and chief scientist at the National Geographic Society, said in NG’s report.
But all of this happens only when this world’s highest weather station will continue to work for a long time. Here I mention the word “long time”, because a temperature of about -50 ° C, and winds with a speed of 225 mph, can damage any technology.
So this is everything about the journey of the world’s highest weather station. Hopefully, today’s article will prove useful to you. Still, if you any questions regarding the world’s highest weather station so you can ask us in the comments section.
About The World’s First Immortal Human Cell Line
Did you know, which were the world’s first immortal human cell line? I know most of us do not know about it, so HeLa cells are the first immortal human cell line. This cell line developed from a sample of cervical cancer cells which was taken from an African-American woman, Henrietta Lacks, on February 8, 1951. The name of this cell line, HeLa, also came from the name of the same African-American woman Henrietta Lacks, the name was composed by the mixing first two letters of Henrietta Lack’s first and last name. Henrietta Lacks herself did not even know about the removal of this cell line from her cells. After researching these cell lines, In 1953, Theodor Puck and Philip Marcus made a clone of hela, which became the first human cell to be cloned and then freely distributed samples of HeLa to other researchers.
Since the cells’ first mass replications, they have been used by researchers in several types of experiments, including disease research, gene mapping, the effects of toxic substances on organisms and radiation effects on humans. Although the primary use of the Hela cell line was for cancer research but HeLa cells gave many other medical breakthroughs and gave approximately 11,000 patents.
Why HeLa Cell Line Known As Immortal Cell Line?
These were the first human cells that grew up in a laboratory that was naturally “immortal”, which means that they do not die after a certain number of cell division. Usually, human cell culture dies within a few days after a set number of cell divisions, which process is called senescence. This causes a problem for the researchers because experiments with using normal cells can not be repeated on identical cells (clones), nor can the same cells be used for extended study. Cell biologist George Otto Gay took one of the HeLa cells and divide that cell, and found that if the cell was given proper nutrients and appropriate environment then the culture survived indefinitely. The original cells continued to mutate.
Hela cells are able to split frequently, they have an enzyme called telomerase, overactive telomerase rebuilds telomeres after each division, prevents cellular aging and cellular senescence, and allows permanent division of cells. Now, Hela has many strains, all get from the same cell. Along with this, HeLa cells grow easily and abnormally fast; they double cellular count in only 24 hours, making them ideal for large-scale testing. They grow so fast that they can contaminate other cell cultures and overtake them. Although there are other immortal human cells also exist but HeLa cell line is the first among them.
HeLa Cells Use in Research
As I mentioned above, HeLa cells used by researchers in several kinds of experiments such as disease research, gene mapping, the effects of toxic substances on organisms and radiation effects on humans, etc. In all these uses, in my opinion, the most important application of HeLa cells is in the development of the polio vaccine, and that was when polio was becoming one of the biggest deadly diseases. In 1953, a cell culture factory was established to supply salk and other labs along with HeLa cells, And in less than a year, the salak vaccine was prepared for human trials. Hela cells were also used in testing how the Parvovirus infects the cells of humans, dogs, and cats. These cells have also been used to research on viruses such as orophu virus (OROV).
In the year 2011, Hela cells were used in the researches of the novel Hepatamethin Dye IR-808 and other analogs, which are currently available for their unique uses in medical diagnostics, the development of theranostics, the individualized treatment of cancer patients with the aid of PDT, co-administration with other medicine, and irradiation. Also in the year 2014, HeLa cells were shown to be viable cell lines for tumor xenografts in C57BL / 6 naked mice, and later on to investigate the vivo effects of fluoxetine and cisplatin on cervical cancer.
So this everything about the world’s first immortal human cells, HeLa cells. Hopefully, now you may have understood what is HeLa cells and it’s immortality and advantages in researches. Still, if you any questions about the hela cell line or immortal human cell line so you can ask us in the comments section.
How Glass is Made in Factory |Process of Making Glass
Glass, a special kind of metal from which many useful things can be made. We are surrounded by things made of glass, whether it be the glass windows of our house, the windshield of our car, the showcase of our house or our mirror in which we see the reflection of ourselves. Despite having so much available around us, many of us are unaware of how glass is made, and where from it came the very first time. So let’s know everything important about glass and start it by knowing process of making glass…
How Glass is Made
Glass is an amorphous solid. The glass is usually brittle and often optically transparent. Glass is a transparent or opaque material made of inorganic materials, from which many other things are produced. The invention of glass was a huge event for the world and glass has great importance in today’s scientific progress.
Only a very few people know this and you may be also surprised to know that glass is made of sand because the most important material for making glass is silica, which is an integral part of sand.
Silica is found in a free state in nature and is also found as silicate compounds. Silica is most commonly found in quartz form. Now this question will definitely be in your mind that, which type of sand is suitable for making glass, is it the exact sand that we see around us, or any special sand? So the most suitable sand for making glass is one in which the silica content is at least 99 percent and iron as ferric oxide (Fe2O3) is less than 0.1 percent. The sand particles should also be 0.5–0.25 millimeters in diameter. Sand is also washed by water to produce good glass.
To make a glass, the sand and some other material are melted in a furnace at about 1500 degrees Celsius and then after melting perfectly, the molten glass is poured into the grooves, so we can make our desired things. This process looks quite simple, but to make glass you must be proficient in this process.
The most common glass is soda-lime glass which has been used for centuries to make windows and glass glasses etc. The soda-lime glass contains approximately 75% silica (SiO2), sodium oxide (Na2O) and lime (CaO), and many other substances in small quantities.
It is also very important to have some alkaline substances like sodium carbonate for making normal glass. With this mixture, the liquid content is reduced and the fluidization process becomes simple. The glass that is formed by the dissolution of these two substances is known as water glass because it is water-soluble. To make the glass permanent, some type of dibasic oxides such as calcium oxide (lime) or sis oxide also has to be added. Each substance produces certain properties in glass and keeping these properties in mind, mixtures of glass are made.
History Of Glass
Although there is no complete evidence that shows how and when the glass was first discovered but according to some old saying, Humans came to know about glass when some traders placed food vessels on clay slopes on the coastline of Phineasia in Syria. When the fire ignited, they saw a stream of liquefied glass flowing. This glass was formed by the combination of sand and Shore.
Historically, the first method of producing a glass-like glow on utensils was invented in Mesopotamia (Iraq) about 12,000 years before Christ. The earliest glass found in Egypt in the form of molded amulets believed to be 7,000 years before Christ.
With the passage of time, the manufacture of different types of glass in each country progressed with its requirements and scientific advancement. England, France, Germany, and the United States owe a lot of credit for the modern growth of the glass industry.
So hopefully, now you know everything about glass such as how glass is made or the history of glass and the process of making glass in factories but still, if you have any questions in your mind you can ask us in the comments section.
Why does the Moon Actually Change its Shape Everyday?
Every night we see the moon in a new shape, the phases of the moon changes every day, and that we all have watcher and witnessed, so does the moon really change its shape? Can it happen? So what is the reasons, let’s know about it….
Who does not cherish the fine arts of the moon? Where in the sky Sun is always seen in a perfectly spherical shape, but the same moon changes its shape from day to day. This rise and fall of the moon always continues in a sequence. There comes a time when the moon becomes completely lost, which we call the new moon, and when the moon comes in its full form, it is called a full moon. The journey from full moon to new moon takes 15 days. It takes 15 days to reach new moon from a full moon, and again 15 days for the full moon from newmoon. However, if seen completely, there is a difference of about twenty-nine days between one full moon to another full moon. This whole process of changing its shapes known as “phases of moon.”
Before understanding this, it is necessary to know that, like many planets and natural satellite, the moon does not have any light of its own, rather it is the light of the sun falling on it which is reflected to us. When any round object is illuminated, then half of its front is illuminated, but the light does not reach the back part and remains dark there. We can see the same part of the moon which is illuminated. But due to the orbit of the moon, we are not always able to see even that half.
In short, The phase of the moon is how much of the moon appears to us on Earth to be illuminated by the sun.
As I already mentioned, in every 29.53 days the phases of the moon make a complete cycle. As the moon circles the earth, we can only see a portion of the illuminated side of the moon. As the moon orbits or circles the Earth, the phase changes. We’ll start with what is called the New Moon phase. This is where we can’t see any of the lighted side of the moon.
At the beginning of this phase, the moon lies between our Earth and the Sun, and as the Moon revolves around the Earth, we begin to see more and more illuminated sides of the Moon, and this process continues until finally, the Moon does not reach the opposite direction of the earth from sun and we get a full moon. And then as the moon revolves around the Earth, we see less and and less of the lighted side.
So it would not be wrong to say that we have a full moon every night, but we are able to see only the part which has illuminated by sunlight. So it is clear now that the moon does not change its shape, it always remains the same, but it visible in different shapes because of sunlight reflections.
Hopefully, now you may have understood what is the phases of the moon and why moon changes its shape every night. But still, if you have any questions About phases of moon so you can ask us in the comments section.
