COVID 19 causes and treatment 2021

Covid 19

in December 2019 there was a cluster of pneumonia cases in the city of Wuhan in China some of the early cases had reported visiting or working in a seafood and live animal market in Wuhan . Investigations found that the disease was caused by a newly discovered corona virus the disease was subsequently named
Covid 19. Covid  19 spread within China and to the rest of the world
on 30 January 2020 the World Health Organization declared the outbreak a public health emergency of international concern .in this article  we'll take a quick look at what is currently known about Covid 19 keep in mind that this is a new disease and what's known is rapidly evolving and might change in the future.so what is a corona virus. corona viruses
are a large group of viruses they
consist of a core of genetic material
surrounded by a lipid envelope with protein spikes this gives it the appearance of a crown crown in Latin is called Corona and that's how these viruses get their name.  there are different types of corona viruses that cause illness in animals and humans in umans corona viruses can cause respiratory infections ranging from the common cold to more severe diseases these include the severe acute respiratory syndrome.  coronavirus first identified in china in 2003 . the Middle East respiratory syndrome coronavirus that was first identified in Saudi Arabia in 2012 and Tsarskoe v2 the name of the virus that causes covid 19 that was first reported in December 2019 . so where did this new virus come from it's known that corona viruses circulate in a range of animals sometimes these viruses can make the jump from animals to humans this is called a spillover and could be due to a range of factors such as mutations in the virus or increased contact between humans and animals .
animal reservoir of the new corona virus is not known yet how does the disease spread the disease can spread from person to person through droplets when an infected person releases those droplets through coughing talking or sneezing for example when close to another person it can also spread when infected droplets land on objects and when another person touches them and then touches their eyes nose or mouth .

SYMPTOMS OF COVID 

What are the symptoms of covid 19 ?the symptoms the incubation period which is the time taken from exposure to the virus and development of symptoms is on average five to six days but can range from 1 to 14 days

there can be a range of symptoms from very mild to severe.  some people may not develop symptoms common symptoms include fever fatigue and respiratory symptoms. such as cough sore throat and shortness of breath some people reported loss of their sense of taste or smell and some may develop a skin rash.  in more severe cases there could be pneumonia organ failure and sometimes death about 80% of cases recover from the disease without
needing special treatment but there are some people who are at risk of serious illness . they include older people or people with underlying medical problems such as chronic respiratory disease obesity diabetes high blood pressure heart disease or cancer .  how can we tell
whether someone is infected .
Theinfection is commonly diagnosed by a test called reverse transcriptase polymerase chain reaction generally
 known as PCR this test identifies the virus based on its genetic fingerprint. there is also a blood test that can check for antibodies against the virus which may show that someone was infected in the past. 

HOW CAN IT BE TREATED ?

 

treatment for covid 19 is mainly supportive care medicines against the virus are currently under investigation how do we prevent transmission of the virus . there are a number of effective ways to prevent the spread of the disease
these include covering your mouth and nose when coughing or sneezing with a flexed elbow or tissue and throwing the tissue in a closed bin immediately after use . wash hands regularly 5 soap and water n maintaining at least one meter distance from people and the appropriate use of masks and personal protective equipment especially in health settings. 

important to stay home if you're feeling unwell and to call a hotline or your medical professional but if you have a fever cough or difficulty breathing seek medical care early and share your travel history or contact with someone unwell with your healthcare provider . In some areas governments have implemented specific physical and social distancing measures to prevent the spread of the outbreak it's important to follow their advice vaccines to prevent  covid 19 are currently under development and scientists around the world are working hard to make this happen that's a quick.

WORLD IN 2050

   From things in the air, to new things for our bodies, join me as we explore 2050: What Would Be The Future Technology? (The World in 2050 Future Technology) We are in the year 2020, and if we're being honest with ourselves, technology is incredible advanced, and we're making strides that can push things even farther. We have cars that are much safer than they've been in the past decade, and we're even making

fully electric cars that can help save the planet. There are even plans for self-driving cars and even self-driving Ubers that make the future of transportation very exciting.
 And that's just ONE technology that we're growing at a fast rate. What about all the others that are out there?

What will technology be like as we get closer and closer to 2050? Let's start with one that well and truly could happen very soon, drones.
"Wait a minute, drones are already here!" and yes, they are. But more times than not the drones you are seeing are small, piloted by people who are just trying to have some fun, or, are the ones that are used by the military right now for strikes and surveillance. All very fun, but in the future, drones could be an integral part of our daily lives.
You've likely seen shows and people talk about how in a few years drones could be the new deliver services. Anything from pizza to Amazon packages, and more. And honestly...that's very probable. Drones right now can be incredibly sophisticated, and some TV shows actually use them for sweeping and aerial shots as they film, it's very cool. But to do deliveries, that'd have to be a little more programmed, as human error no doubt would be a very big buzzkill.Not that it's impossible right now, it's more of a question of numbers, logistics, costs,and making sure that the deliveries themselves are done in a methodical and careful manner. After all, it's bad enough when delivery people don't care enough about our packages that
they just throw them onto the porch and potentially break stuff, the last thing we need is that to happen with drones.

                        But by 2050?We might not only have drones delivering out packages, we might be looking up at the sky and seeing drones flying all over with incredible speeds and accuracy, and they potentially could all be run by AI!  The potential is there, and by that point various upgrades to drones and their programming will no doubt make them all the more efficient, durable, and quick. And potentially, they could go beyond basic deliveries for people and do emergency work. Imagine a drone taking a vital piece of medical material to a hospital to ensure it doesn't get stuck in traffic? Or helping watch over an important convoy to let people know on the ground if there is trouble? There's many ways that drones could affect our world, the only question is, will we let them by 2050?

Let's keep going with transportation, shall we? Right now, one of the biggest ways to get around the countries we live in are trains. Trains ferry people and all sorts of cargo around in an efficient and reliable manner, which is why they've been in use for hundreds of years.But...if we're being honest here, while trains are efficient and reliable in certain ways...they aren't exactly fast. Especially when it comes to passenger and freight trains.They can take a LONG time to get to their destinations and at times it's more logical to take other modes of transportation. Which is why companies are making special kinds of trains that can go MUCH faster.
Now let's go to something a bit more...unique.
Look at yourself right now, specifically, look at the clothes you are wearing right now. What are they made of? What do they feel like?
What do they look like? Of all of these answers, I bet none of them are, "they look like they can give me superpowers". Because they can't.
Not yet anyway... Think about it like this, what if the clothes you were wearing right now felt the same,
looked the same, but could do more?
With the growth of nanotechnology, your clothes could potentially be imbued with various materials
or technologies that help you improve your strength, durability, and more.
For example, what if you had a shirt on that was light as a feather, but could absorb impacts and leave you with no injuries? That would be pretty impressive, and important, especially in this age of gun violence we live in. Or, what if the uniforms of firefighters made them completely heat-resistant and burn proof?Further ensuring that they are able to do their jobs without much risk to their lives. The technologies that we can put into clothes is out there, and some people are working on it right now both in terms of multiple functions, but also, cosmetic appeal.
Imagine if by 2050 we have the ability to craft whatever kinds of clothes we want, and even select what kind of "abilities' they have?
Imagine you wear a special kind of top that has a special pattern on it, and then when you press a button or say a keyword that pattern unfolds and suddenly you have wings on your outfit. Wouldn't that be cool? If done right, this could be the newest wave of fashion and style in the future.
 Finally, let's talk about something that I'm sure you'll be horrified to hear . In the future...you likely won't need a phone. I know, you're stunned, but think about it, right now, smartphones are becoming more and more advanced every single year. New features, new programs, etc.

But by 2050, your phone won't likely need to exist because you'll have access to it and more via something else. What exactly? That depends on the technology . 

What is AREA 51 ?

 Mistory of AREA 51

 IN the early 1950s us planes were conducting low-flying recon missions over the USSR but there were constant worries of them being spotted and shot down so in 1954 President Eisenhower authorized the development of a top-secret high-altitude recon aircraft dubbed Project Aqua tone the program required a remote location that wasn't easily accessible to civilians or spice area 51 fit the bill perfectly it was in the Nevada desert near a salt flat called groom Lake .no one knows exactly why it's called area 51 but one theory suggests it came from its proximity to the Nevada nuclear test sites 

 The Nevada Test Site was divided into number designated areas by the Atomic Energy Commission the location was already familiar territory for the military as that it served as a world world two aerial gunnery range.

 In the summer of 1955 sightings of unidentified flying objects were reported around area 51 that's because the Air Force had begun its testing of the  aircraft the  can fly higher than 60,000 feet at the time normal airliners were flying in the 10,000 to 20,000 feet range while military aircraft topped out at around 40,000 feet so if a pilot spotted the tiny speck that was the u2 high above it they would have no idea what it was and they would usually let air-traffic-control know someone was out there which is what led to the increase of UFO sightings in the area while Air Force officials knew the UFO sightings word u2 tests they couldn't really tell the public so they explained the aircraft sightings by saying they were natural phenomena and high-altitude weather research the testing of the u2 ended in the late 1950s but area 51 has continued to serve as the testing ground for many aircraft including the f-117 a the a12 and the tacit blue no one knows for sure what area 51 is up to these days the government never even publicly acknowledged the existence of the base until 2013 with the release of

declassified CIA reports but if you're ever at the Las Vegas Airport keep an eye out for some small unmarked passenger planes in a fenced off area they're how area 51 employees get to work from their homes in Vegas.

 

AMAZON SELLING IN PAKISTAN

 if you are from Pakistan and you are looking how you can make money by selling on Amazon then first you have to know these things. In this article will try to  explain what do you need to do to start selling on Amazon if you are from Pakistan if you don't know how you can make money by selling on Amazon.

right now I'm assuming that you already know how you can make money by selling on Amazon and you want to start doing it  but you just don't know how you can start because you are not from United
States and because of that you have
 different requirements you need to
follow if you want to sell on Amazon.

So I'm going to explain all
these requirements and give you solutions or the things you need to do in order to sell on Amazon . So  let's get started from the very beginning so you need to know that Amazon divides sellers into groups based on the country that you are living in so Group one are the people living and based in the United States, group two are the people based in the country supported by Amazon,3 Payments group three are the people based in the countries not supported by Amazon Payments but  allowed to sell an Amazon and the group four are the countries not allowed to sell on Amazon .  I have a good news
unfortunately not the best that Pakistan is in the group three countries not  supported by Amazon Payments  but allowed to sell on Amazon that means  that you can sell and make my Amazon that they did not accept your  country's payment methods such as your  bank accounts credit or debit cards and  that's where I'm stepping in and helping you out.

SO like I said you cannot get
money from Amazon in your country's bank  account or credit or debit card that  means you need to open a bank account in  United States don't worry it's much  easier than you think and the solution  is Payoneer bank account it is commonly  used by Amazon sellers who are on the  group three or four you need to sign up
 for a penny account to receive payments and then you can transfer payments from Payoneer bank account to your home bank account or your home credit debit card to open appear near bank account you can find the link down below only using my link you will get $50 back after your first deposit. 

                                    AS I forgot to mention  what is Payoneer? so Payoneer is bank based in United States when you open account with them you will get virtual debit card you can use that also you will get the most important thing what you need you will get all the bank information like routing number account number so you use that to open and attach that bank account to your Amazon sellers account now you may ask what information you need to have to open at Payoneer bank account so you need to provide your full name address where you live phone number and for verification purpose you need to provide one of the other passport national ID or your driving license. Once you have Payoneer bank account you are ready to open Amazon sellers account. You don't need anything else that's how you can start earning money by selling on Amazon.

Brain changing benefits of exercise

 

   What if I told you there was something that you can do rightnow that would have an immediate,positive benefit for your brain

including your mood and your focus.

And what if I told you that same thing could actually last a long time and protect your brain from different conditions like depression, Alzheimer's disease or dementia. Would you do it?

Yes ; I am talking about the powerful effects of physical activity.Simply moving your body has immediate, long-lasting and protective benefits for your brain And that can last for the rest of your life. So what I want to do is tell you a story about how I used my deep understanding of neuroscience to essentially do an experiment on myself in which I discovered the science underlyinh that is the thing in our head right now, lets consider a real  human brain. And it's going to illustrate two key areas that we are going to talk about today.The first is the prefrontal cortex, right behind your forehead critical for things like decision-making, focus, attention and your personality.The second key area is located in the temporal lobe, shown right here. You have two temporal lobes in your brain, the right and the left and deep in the temporal lobe is a key structure critical for your ability to form and retain new long-term memories for facts and events. And that structure is called the hippocampus. So I've always been fascinated with the hippocampus. How could it be that an event that lasts just a moment say your first kiss, or the moment your first child was born, can form a memory that has changed your brain,that lasts an entire lifetime?
That's what I want to understand. I wanted to start and record the activity of individual brain cells in the hippocampus as subjects were forming new memories. And essentially try and decode how those brief bursts of electrical activity, which is how neurons communicate with each other how those brief bursts either allowed us to form a new memory, or did not But a few years ago, I did something very unusual in science. As a full professor of neural science,I decided to completely switch my research program Because I encountered something that was so amazing with the potential to change so many lives
that I had to study it. I discovered and I experienced the brain-changing effects of exercise.
And I did it in a completely inadvertent way. I was actually at the height of all the memory work that I was doing , data was pouring in , I was becoming known in my field for all of this memory work.And it should have been going great. It was, scientifically. But when I stuck my head out of my lab door,I noticed something. I had no social life.I spent too much time listening to those brain cells in a dark room, by myself.I didn't move my body at all.
I had gained 25 pounds.And actually, it took me many years to realize it,

I was actually miserable. And I shouldn't be miserable ,And I went on a river-rafting trip -- by myself, because I had no social life.And I came back thinking, "Oh, my God, I was the weakest person on that trip And I came back with a mission.

I said, "I'm never going to feel like this .
