The Real Monster Of The World

Hey guys ,
      How much low/high temperature you can tolerate????

Can you live in space without oxygen???

Can you tolerate the water pressure of deepest ocean?

Can you live without any kind of food or water for 30 years?

Your answer is "NO"

But trust me, this animal can do all of the above!!!
Tardigrade (Toughest animal in the world)
Tardigrade: toughest animal in the world,

Everything We Know About Tardigrades, the Only Animal That Can Survive in Space.The tardigrades were in "tun" form, a dormant state where they shrivel up into a ball, expel most of the water in their bodies, and lower their metabolism via cryptobiosis until they enter an environment better suited to sustain life.

How much low/high temperature they can tolerate????

Basically, 
tardigrades can survive: A few minutes at 151 °C (304 °F) 30 years at −20 °C (−4 °F) A few days at −200 °C (−328 °F; 73 K).
Someyears ego , scientists boiled it at 151°C for long 15  minutes, they noticed that nothing is happened to this animal.

Survive in space:

In 2007, A European team of researchers sent a group of living tardigrades to orbit the earth on the outside of a FOTON-M3 rocket for 10 days. When the water bears returned to Earth, the scientists discovered that 68 percent lived through the ordeal.

Although (as far as we know) tardigrades are unique in their ability to survive in space.

How they can do that kind of things is still unknown. Scientists are still observing it.

If you think, they live in a particular place, then you are absolutely wrong.They are everywhere in the world,,they may be a few meters away from you or may be not.

One thing you need to know that it is impossible to kill an tardigrade , you can boil them but can't kill them.

Golden Blood

What is Golden Blood? Does it really exist?

Hey my viewers, 

You may be wondering, what the golden blood is again ! So , before we discuss about the Golden Blood , you must need to know about Rh Blood Group System & Rh-null Blood. So let's start ❤️


Rh Blood Group System:- 

The Rh blood group system is one of 36 known human blood group systems. It is the second most important blood group system, after the ABO blood group system. The Rh blood group system consists of 49 defined blood group antigens, among which the five antigens D, C, c, E, and e are the most important.

Rh-null Blood:-

If blood  lacks all of the 61 possible antigens in the Rh system then it's called Rh-null Blood.This not only makes it rare, but this also means it can be accepted by anyone with a rare blood type within the Rh system. This is why it is considered "golden blood.

What is Golden Blood?

One of the rarest blood types in the world is Rh-null , sometimes referred to as Golden Blood.

You may already know your blood type: whether it’s A, B, AB or O, and whether it’s positive or negative. But those are just the most common categories—what about the rest? What about people with ‘rare’ blood?

There are hundreds of different antigens across more than 36 blood group systems that may be present on our red blood cells. For example, you may have AB blood in the ABO blood group system, be Rh positive in the Rh system, as well as being K positive in the Kell system, and so on.

You have a ‘rare’ blood type if your blood is missing an antigen which is common to most people, or if it has an antigen which most people don’t have. Say your blood lacks an antigen which is present on the red cells of the majority of the population. If you receive a transfusion of ‘ordinary’ blood which has that common antigen, it will be recognised as foreign, triggering an immune response with potentially catastrophic results (harmful or disastrous)

Why does chopping an onion make you cry?

When we cut onions, we often say that "Hey Mom , my eyes are burning 😭😭huaaaa"

So , have you ever thought about the reason? 

Why does chopping an onion make you cry?


Onions produce the chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes’ lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion.
          Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit.



The process goes as follows:

  1. Lachrymatory-factor synthase is released into the air when we cut an onion.
  2. The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid.

  3. The unstable sulfenic acid rearranges itself into syn-propanethial-S-oxide.

  4. Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands become irritated and produces the tears!
