Corona Virus at a glance

Corona Virus at a glance

Corona Virus at a glance 

Researchers claim that coronavirus has spread from bats to China. Recently, two studies were published in the journal Nature. These studies have shown that coronas, such as SARS (Save Acute Respiratory Syndrome) virus, also spread from the bats.

The first study was done by Feng University teacher Yang Zhen Jung and one of his colleagues. They collected samples from a patient's lungs for research. The patient was admitted to the hospital with symptoms of fever. The patient was working at the South China Seafood Wholesale Market.
A sample analysis from that person showed that the coronavirus was similar to the SARS virus. This coroner genome sequence corresponds to the CARS's genome sequencing of 5.7%. Earlier in China, circus was spread in 20, which spread from bats.

 Another study, published in Nature, says that the researchers analyzed the data and found that the virus had spread to the bats. It is a virus similar to the SARS virus.

SomeQuestionares about CoronaVirus:
##.What is the duration of symptoms of the coronavirus in the body of the person?
Answer: According to the World Health Organization(WHO), it can take a minimum of 7 days to determine if a person has been infected with the coronavirus. This is because the virus can remain dormant in the person for 2 to 3 days before the symptoms are revealed. However, this time may be shorter.

##. How to spread the SARS (Save Acute Respiratory Syndrome)? How did it get started?

Answer: Another type of coronavirus is the SARS (spread in 2013). The virus was infected with bats. Later it spread to the bodies of those who had contact with the Fox. Then the cough and coughing of these persons spread to the bodies of others, with the objects they had taken.

Runs on the top of the moon's water

Runs on the top of the moon's water
If you've ever gone canoeing, you may have noticed water striders,  those small, long-legged bugs that easily stroll across the surface of the water without breaking the surface tension. In Central and South America, the slightly larger basilisk lizard can pull a similar trick, but it has to move pretty fast to do it. And we seem to remember a story about another guy way back when who was kind of famous for walking on water (not sure if that had anything to do with surface tension, though). But actually, a lot of people can perform that "miracle" — as long as they go to the moon first.

A Whole New Way to Moonwalk

What kind of people do this important research into the human capacity to traverse theoretical lunar swimming pools? The same kind of people who win Ig Nobel Prizes. The 2013 science gag prize in physics went to a team of Italian scientists who wanted to find an answer to that question. Their findings? It's possible — but difficult.
To get their results, the scientists devised a brilliant simulation of lunar gravity consisting of a springy harness hanging from the ceiling. They then equipped their study participants with swim fins to mimic the broad feet of basilisk lizards, because while low gravity, high speed, and broad feet can each on their own help with the endeavor, the best way to get results is to combine all three. The researchers rigged the harness to simulate various amounts of gravity and found that the most physically fit of their participants was able to stay afloat at about 22 percent of Earth's gravity. Reduce that amount down to 10 percent, and almost everybody was able to do it. Since the gravity on the moon is about 17 percent of Earth's gravity, that means that running across a lake is certainly possible — it's just closer to the "elite athletes only" side of the spectrum.
By the way, if you think that the sight of somebody strapped into a complicated harness, wearing floppy swim fins, and splashing frantically at the top of a pool of water would be a pretty funny sight, shame on you. This is serious science. And also, you're totally right.
