Some new scientific records for 2020

By 2020, the whole world is in turmoil in Corona. The people of the world have been under house arrest for a long time. But nature is following the rules of nature. During this time many scientific events have taken place. Scientists have done research on various subjects. Searching for unknown information. They have noticed some incidents which have overshadowed the previous ones. Got something that is longer or older than before. Throughout the year, records have been set in various fields of science. This event is organized with 10 scientific facts that will create a record in 2020 .

The biggest turtle

The largest tortoise ever found orbited the earth about 6 million years ago . The shell of the tortoise is about 6 feet in diameter. The shell was recently found in Venezuela. The tortoise belongs to the extinct Stupendemys geographicus species. It lived in North-South America during the Miocene period. It weighed about 2,500 pounds (1,145 kg) , a hundred times more than the Peltocephalus dumerilianus tortoise, which lives in the Amazon rainforest . It is twice the length of the largest living tortoise ( Dermochelys coriacea ).

Researchers have studied these shells and found that the male tortoise had horn-like weapons to defend itself and win the battle to find a mate. But this horn was not enough to deal with the predators which can only be understood by looking at the crocodile tooth marks on its shell.

The longest animal

The longest animal ever found in Australia’s deep sea in 2020 . Its length is 150 feet (48 meters). Such a large animal has never been seen before. The animal’s name is Siphonophore. Siphonophores are transparent animals like threads that are formed by a combination of more tiny creatures. These tiny creatures are called Jewids. Although the Jews live different lives, they all act as the body of the siphonophore when they are connected to each other. Until now, researchers have found a 130-foot siphonophore. This time, the researchers found this longest animal using a remotely operated vehicle (ROV).

The longest tour of birds

A godwit ( Limosa lapponica ) has broken the record for the longest flight in 2020. The bird flew from Alaska to New Zealand for 11 consecutive days. During the long voyage, the bird traveled more than 7,500 miles (12,000 kilometers). This is by far the longest tour for birds.

These birds usually migrate from Alaska to New Zealand. However, a certain bird has traveled far more than this distance. Because it had gone too far because of the wind. As a result, this bird has to travel extra distances more than its own species.

Scientists identified the bird with the help of a satellite and named it 4BBRW. It is named because of its blue, stacked blue, red and white tails. Scientists then began to observe the bird. The bird landed in New Zealand 11 days after leaving Alaska. During this time the bird traveled a distance of 6,561 miles (12,200 km). The speed of the bird on the journey was 69 kilometers per hour. Earlier in 2006, another Godwit bird covered a distance of 6,145 miles (11,500 kilometers).

Ancient twin children

The oldest known twins have been found in Austria. Their remains were recovered from an archaeological site in Krems-Watchberg. The oval curve was discovered in 2005.

Since then, research on the corpse has continued. In 2020, researchers said, the two remains are 31,000 years old . Of that ancient Stone Age. According to DNA research, these two children are the oldest twins ever discovered. One of them died in childbirth. Another died 50 days after birth. The necklace of mammoth teeth was found in the tomb. Elephant shoulder blades were placed over their bodies to keep the two bodies intact. The researchers analyzed isotopes of carbon, nitrogen and barium in the tooth enamel of the two bodies, adding that the baby was breastfed after birth.

Maximum speed of sound

How fast can sound cross the path? There is a lot of research going on. We know that words move at different speeds. How fast the sound goes depends on what medium the sound is going through. For example, sound travels faster in hot water than in cold water. It moves at different speeds through solid, liquid and gaseous. But what is the maximum speed of sound? Kostia Trachenko and her team at Queen Mary University in London have done research on this.

The theoretical results of the study suggest that the maximum speed of sound may be 22 miles per second (36 km / sec). They reported that sound travels the fastest in atoms of the lowest mass. They took the initiative to test their theoretical results. For this he took the hydrogen atom. But even though hydrogen is the lowest mass atom, it is not difficult. Run the test on that kind of quantum machine to test it in difficult conditions. They measure the speed of sound by moving the sound in it to turn the hydrogen atom into a solid state under very high pressure. It can be seen that the sound can travel at a speed of 1 lakh 26 thousand 480 kilometers per hour. In other words, the maximum speed of sound can be 36 kilometers per second.

The longest light of lightning

What is the length of the light that is seen during lightning? Our guess is that its length will not be too much. But if said, the longest lightning record ever recorded is more than 400 miles (600 km) long . Then you must be surprised. But that is the truth.

In 2016, the longest flash of light was seen in Brazil. For example, its length was from eastern Argentina to the Atlantic . Although the event took place in 2016, researchers announced in 2020 that it was the largest lightning strike ever recorded. The data has been confirmed by the World Meteorological Organization (WMO). Earlier, the length of the largest lightning strike was 200 miles. It was first seen in Oklahoma in 2006.

The oldest sperm

The oldest (so far discovered) sperm has been found in a mine in Myanmar. The sperm was in the amber in the mine. Amber is a special plant-derived adhesive. No matter what small insects or animals or anything else gets stuck in this sticky substance, it does not get damaged but over time it becomes a mummy. It is the oldest sperm ever found by humans. The earliest known human sperm was 50 million years old. But the sperm found in mines in Myanmar is about 100 million years old.

The oldest material found on earth

Scientists have identified stardust (star dust) found inside a meteorite that struck Earth half a century ago as the oldest element found on Earth.

Stardust is about 6 billion years old. In ancient times this dust fell from a dead star towards the earth. It landed in Australia in 1989. Since then, various researches have been going on about it. In 2020, researchers said that stardust is the oldest element found on Earth. But the most surprising thing is that some particles have been found in this stardust that were formed even before the sun. Our sun is 4.70 billion years old. But some of these stardust particles are more than 6 billion years old . Some particles are more than 4.6 billion years old.

Maximum ‘Long Exposure Photo’

Exposure has to be adjusted while taking pictures with the camera. Long exposure is a picture that takes a lot of time. During this time only the slowest and slowest characters appear in the film. High speed characters do not appear in the picture or become blurred. But the longest exposure time ever taken may be beyond your comprehension

The highest exposure time taken so far is eight years and one month . A master’s student in the Department of Fine Arts at the University of Hertfordshire made a pinhole camera with a beer can to take pictures of the sun. He then placed the pinhole camera in a telescope. But he forgot about that project. However, in 2020, it was possible to recover the image taken at that long exposure and it has been recognized as the image taken at the longest exposure in the world. The longest exposure taken before this film was four years and eight months. That picture was taken by German artist Michael Wesley.

The most ancient intestine

Researchers have discovered an intestine 550 million years ago in the Nevada desert . This is the oldest intestine found so far.

Amy Smith, a member of the research team, said it could be an extinct Claudina species that looked a lot like a worm. 570 to 540 million years ago, towards the end of the Idikaran period, strange, soft-bodied creatures appeared on Earth. Dr. Schiffbauer and Dr. According to Sally, Claudina was a member of the Idiacara fauna. As a result, the intestine is 550 million years old. The researchers identified this intestine from fossils using a CT-imaging technology .
