Spicy Food for a Happy Stress Free Life

By Anupum Pant

Today I’d like to start with something called Morphine. There is great chance that you already know about Morphine, may be through House MD, or other things. If you do, you could skip if you want to. But reading through a couple of lines never hurt anybody.

Morphine: is one of the most effective drugs used in medicine to relieve severe pain. It acts directly on the central nervous system, relieves anxiety and produces euphoria – intense happiness. That is the reason, it is also widely used illegally as a recreational drug. Wait! It is highly addictive too. But what makes me talk about morphine today?

Endorphins: And then there are Endorphins. Endorphins, short for Endogenous Morphine, is a morphine like substance made by the body – Where endogenous means that it originates inside the body. The amount of it released in the body is completely dependant on how you live your life and the kind of food you eat.

Like morphine, Endorphins have some function in the body too. In simple words, they relieve pain and stress. For instance, in a body builder’s body, these are the natural chemicals which keep them going in the gym, by mitigating pain sensation. And of course, since it is nothing but Morphine occurring naturally in the body, it creates Euphoria, or a state of intense happiness.

Runner’s High: People who are engaged in strenuous activities often have high amounts of Endorphins being released inside their body. As a result, they develop something called a runner’s high – An addiction to exercise and other strenuous activities. May be this is how workaholics are born. I’m guessing, endorphins is the chemical that gives the Tarahumara people the ability to run for 400 miles. And may be Marathon Monks of Japan also have unlocked a technique to produce high amounts of Endorphins in them (meditation!).

Whatever it is, healthy amounts of Endorphins released in the body make you happy, and a greater amount than that only takes you to a super human level. Of course, using morphine without prescription is not legal. But, there’s no law that can stop you from creating it in your own body. After all, it can completely change you as a person.

How to: Now, there are a couple of natural ways you could train your body to make more of it for you. Some of them are – strenuous exercise, a lot of sleep, eating chocolate and meditation (marathon monks!). But, among these techniques, in my view, adopting excessively spicy food is the most accessible and healthy way to go about it. Heck, just eat chillies and be happier. So simple. If you think that is hard, well, the human body can easily be trained…

Among scientists, it is a well-known fact that eating chilli peppers can lead to enhanced secretion of endorphins. It is also noteworthy that spicier the chilli, more endorphins are released. And to find the spiciest chillies, you can probably watch the video below…

So, go, rev it up to 16 Million Scoville Scale unit and lead a happier and stress free life. Use science and get addicted to happiness.

Note: Do whatever, but do not over do it. You don’t want to try the deadly cinnamon challenge to be happy.

Pando – An Organism That Weighs 6 Million KG

By Anupum Pant

Blue whales weigh about 150 tons each. That is a 150,000 kg animal we are talking about! Incredible! It is the largest animal to have ever lived on earth. Yes, bigger than any of the dinosaurs. Just for the perspective, the heart of a blue whale can weigh about 600 kg and is almost the size of a Volkswagen Beetle car. A human can fit in its arteries. But, if you thought no other organism can be heavier than a blue whale, you are in for a surprise.

The heaviest organism we’ve ever found, lives in the Fishlake national forest, Utah. In fact, the organism itself is the forest. This forest is a Vatican-city-sized forest which looks like it has several identical trees in a normal forest. Only what looks like identical trees in a normal forest, is actually a single huge tree.

The absolutely humongous tree is known to have come out of a single seed about 80,000 years back. With time, it went on to spread its roots and has cloned itself by popping out about 47,000 other extant clones.

Since it is a single huge tree, it indeed acts like a single huge tree. When one of the shoots (tree) is in need of nutrients, the interconnected root system makes sure that the tree gets what it needs. Also, these trees transition from winter to spring simultaneously, just like a single huge tree would.

Extreme Bionics – Artificial Limbs as Good as Real Ones

By Anupum Pant

Hugh Herr is an American rock climber, engineer, and biophysicist who lost both his limbs below the knee due to a bad climbing accident. He now heads the MIT Media Lab’s Biomechatronics group. In the following talk he talks and shows off an incredible new kind of prosthetic they’ve developed.

The guest appearance of Adrianne Haslet-Davis, a dancer who lost a limb in the 2013 Boston bombing, makes it so touching. Don’t miss that.

So, here Herr giving one of those greatest talks you’ve ever seen. It’ll makes you realize how science is bringing closer a glorious future. If we keep moving at this pace, soon there will be a day when there will really be no disabilities. That is all I want to say.

The Sweet Tale of the Mysterious Tree Lobster

By Anupum Pant

I do realize how big our world is and the sheer number of species that live in it. Also the fact that about 86% of the species are still unknown has me in awe all the time.

Yet, after having read about so many kinds of animals that live on our planet, after having documented them on this blog, I always feel that I’ve known and written it all. The very moment I start losing hope that I would never find an interesting animal ever again, something incredible comes across. Always!

Today, that happened again when I was reading an NPR blog. This time, there’s more than the species itself. The place where it lives is pretty awesome too. The most amazing part – This six-legged giant lives only there. That means, nowhere else on Earth will you find it! First, let’s see where it lives…

This is where it lives:

balls pyramid

I know, it looks like a CG mountain done for a fantasy movie. Trust me, it’s real. It’s called the Ball’s Pyramid (named after a European named Ball who first saw it in 1788) and was formed 7 million years ago due to a volcanic eruption. It is an awkwardly tall (1,844 feet) and an extremely narrow rock sitting in the centre of the sea. To the East of Australia, the red place marker in the following picture shows where the rock is located.

balls pyramid location

 What lives there? And how was it found?

There is an island – Lord Howe island – close to the rock. In the island lived huge “tree lobsters” (actually they were huge stick insects with a hard exoskeleton – Dryococelus australis). In the year 1918, a ship crashed on the island and brought with it some rats. The rats loved these tree lobsters and finished them off within 2 years. After 1920, these tree lobsters were thought to be extinct.

tree lobster

Of course there were stories of these insects living on a rock near the island. But no human wanted to climb the narrow rock to hunt insects at night.

Only in the year 2001 when 2 researchers David Priddel and Nicholas Carlile decided to climb up the rock to find out if these stories were real, they found something incredible. Poop of a large insect. When the came back at night to investigate, the shiny black huge tree lobsters were found! These insects had probably never been extinct.

For more than 80 years, 24 of them had been living on this rock, in a bush and no one knew how they got there. Probably they clinged on to birds or something. Also, according to the researchers, these creatures have never been seen anywhere else.

Where are they now

I’m not sure about where they are now. According to the 2012 NPR article which I read, a pair of these creatures – Adam and Eve – were brought into Australia. Eggs got laid and little Tree lobsters came into the world. Thankfully, the species was saved from going extinct. But it isn’t known if they’ll be sent back to their home island because the great-great-great grandsons of those rats must still be there waiting to finish these insects off again.

This is how the first ones hatched in the zoo…

Planarian Worm – Cloning a Creature was Never This Easy

By Anupum Pant

Lizards grow a new tail if the old one is lost. In fact, they even shed it of voluntarily to save themselves from predators. Then start fish can grow their cut arms back, earthworms can grow back cut parts too. Even Axolotls are pretty good at regeneration. But there is probably nothing as strange as the Planarian flatworm.

If you happen to slice a Planarian worm into half, vertically (or any other way), both the parts will regenerate! So, in 2 weeks you’ll have 2 Planarian worms cut out of a single one. The ability to regenerate is so good that even if a 1/300th part of this worm is cut, the small bit of it can regenerate the rest of the worm! But that isn’t even the strange part.

Now, naturally, since it can grow back its body, it can grow back its head too. But the most amazing part is that with the new head, the old memories of the flat worm also come back! That is strange, isn’t it?

With just a knife in your hand, cloning was never so easy.

Fun Fact: Planarian Flatworms also do not have a separate anus. But they do have an cavity at the rear end which they use to take in food. The same cavity is also used to send out the waste stuff.

Scientific Ways to Make Cut Flowers Last Longer

By Anupum Pant

Suppose, someone gives you a beautiful bouquet, celebrating a very important day of your’s, say your 50th wedding anniversary – A rare event these days. Wouldn’t it make you happier if these precious flowers last longer, even if it is just “slightly longer”? If you are a person like me who is easily moved, seeing flowers last longer would certainly make you happier!

Here are a few simple scientifically proven ways you could try that would make your cut flowers last slightly longer.

Sprite or 7-Up

Well, to make a flower last for about 3 days,  of course you could cut off an inch of the stem, clean it and put it in plain water. But there is also a little addition you can do to the water to keep them blooming for a few more days.

Add some amount of sprite or 7-Up to the water. Yes, that’s it. I know, some would consider it an urban legend or a forwarded email story, trust me, it actually works. Continue reading Scientific Ways to Make Cut Flowers Last Longer

Wood Frog Dies and Comes Back to Life

By Anupum Pant

Ice Kills

Everybody knows what extremely low temperatures can do to our body. If you aren’t well protected from the cold, unable to retain the heat, the core temperature of your body may drop below 35 degree C and can cause some serious problems, even death.

At even lower temperatures, ice crystals can form in the tissues and puncture blood vessels. Ice crystals may even squeeze, deform and break cells. Otherwise it can leave behind shrunken and destroyed cells by sucking out water from them to form ice. Probably leaving you with a permanently damaged body part.

Due to ice formation inside the cells, this disastrous structural damage that is caused in human bodies, or most other organisms is unavoidable. We were not built to endure horrendous cold. But there are a few organisms who are built to live, or if I may say, die and then live again in extremely cold temperatures.

Meet the Wood Frog

Wood frog, a small variety of frog found in north america is one such creature. You ask what’s so interesting about them?

It is probably one of the most freeze tolerant beings. In other words, extracellular freeze tolerance and intracellular freeze avoidance enables the frog to do what it does.

Well, when it is really cold out there in the Arctic circle or the upper parts of America, they can freeze themselves for weeks, even for months. It does this by first finding out if it is really cold out there. When it touches the first bits of winter snow, a signal sets off in its body and the signal starts the blood freeing process.

All the water is pulled away from the core of its organs and the water gets frozen. Putting all the organs in a shell of solid ice. The whole frog becomes hard as a rock and sits there like that for weeks. Till it sees the spring time.

The most amazing part is that, during this time, the frog doesn’t breathe, its heart stops beating and even kidneys stop functioning. In medical terms it could be called dead. In reality, it is only temporarily dead.

Just like a dead man – without a hear beat – walking.

And then spring comes. It thaws itself out without any cellular injury and starts jumping again. It dies in winter and comes back to life in the next season.

This is probably how carbonite from Star Wars works.

Sad Story of The Lonely Whale – 52 Hertz

By Anupum Pant

Background Story

In the year 1989, a navy technician Joseph George, discovered something mysterious. While looking for enemy submarines in the sea by detecting sound signals, Joseph noticed that there was a mysterious lone sound which stood out in the acoustic signal. From his years of experience as an acoustic analyst, Joseph knew that this sound wasn’t coming from a submarine. As predicted, no enemy ships or submarines were found on further examination.

The sound was a deep pulsing wave and was incredibly loud. It seemed as if it were coming from a machine. But he was certain that this wasn’t a mechanical machine which was making the sound. There was something biological about it. So Joseph decided to call an experienced marine biologist to find out what was making that sound. The researcher confirmed that it was a whale! But not a normal whale…

Did you know?
Whale vomit can make you rich.
and Whale fat is a very healthy thing to eat.

The Twist

If this was really a whale, it still confused the marine biologist because first, the sound was coming from an awkward path. Since whales travel together in a regular migratory path, this wasn’t coming from any of those paths. Also, it was a lone sound.

Secondly, the frequency of sound that was detected was measured to be 52 hertz, and no species of whales were known to make that kind of sound. Usually whales create a sound with a frequency that lies between 15 to 20 hertz. This was definitely not any known species of whale. Or even if it was among any of the known species, it was calling out the wrong note. A note, probably no other whale could hear.

So, for obvious reasons, even when the loud bass was heard for several times, no response by other whales was detected. This was awkward because whales usually respond to the members of their groups. They talk. It was concluded that this whale was travelling alone. No one knew why.

Studies and Theories

In the 13 years of study that ensued, the whale (or whatever it was) was never seen, nor was a response to its song was noted. Scientists started calling it the 52 hertz whale. They could never figure out why the whale sang in a different voice or even an answer to why it was alone, travelling on a completely different path.

Scientists have tried to explain this, but there has never been a solid answer that explains the lonely nature of the creature. To explain the loneliness, some say that the 52 hertz’s voice can’t be heard by other whales, others say that it can’t hear the other whales. Some say that the other whales are scared to respond or go near an unusual voice. Other theories say that the whale must be a hybrid of two different species of whales and that is the reason it sounds so different. What is the real deal, no one knows.

Stories Documentaries and Poems

The 52-hertz whale started having a huge fan following in the late 2000s. A 90 minute documentary was made. However, I couldn’t find it anywhere. Poems were written. Blogs and statuses were written and people sounded touched & concerned. They wanted to extend help to the lonely whale in some way.

The Rainbow Coloured Lake – Grand Prismatic Spring

By Anupum Pant

Of all the “cool” places we have here on earth, lakes and other water bodies fascinate me the most. This is probably the reason I keep stumbling upon some of the most amazing lakes over and over. In the past I’ve written about the Taal lake and the bleeding lake of Antarctica. I have several others in mind, but this is the one I’ve picked for today, and it isn’t “cool” – The rainbow coloured lake.

Lying amidst the colourful geysers and hot springs of Yellowstone National park, located in the state of Wyoming, is a lake where you’ll see colours ranging from brilliant yellow, orange, red, green and of course blue. Here is what it looks like…

The lake is called the grand prismatic spring and it is the largest hot spring in the US. The water there is hot enough to burn you. And yet…

The hot spring, is home to different kinds of tiny living creatures. Organisms called thermophiles have learnt to thrive in the abnormally hot place. In fact, these creatures depend so much on the heat that they can’t live away from the hot water.

What makes it coloured?

The lake is coloured, yes. But what causes these bright vivid colours? Is it because there is something in the air around it, or is it due to a industrial chemicals leaking into the lake, or is it due to these organisms? Whatever causes the lake to appear coloured, that too colours appearing in the same order like they would be seen on a rainbow, I wanted to know.

Turns out, it isn’t just the lake that is coloured. The steam that arises from the hot water comes in different colours too!

The orange and other non-green/blue colours which appear there the most after blue are due to a multi-layered sheet of microorganisms that thrive in the lake. These are pigmented. The main pigment is chlorophyll (the same thing which helps the plants make food). But chlorophyll is green. So there are some other yellow, red and orange coloured pigments called Carotenoids, that protect the chlorophyll when the sunlight is bright enough to damage it.

The colour of the part of lake is a function of, amount of Carotenoids  present with chlorophyll. More the Carotenoid, more colours you’ll see. A greater ratio of cartenoids to protect the chlorophyll during summers is the reason why the lake appears not-so-coloured during winters and vividly coloured during the summers. So, it isn’t the variety of microorganisms or chemicals or atmospheric conditions that colour the lake, the colour is due to the different mix of chlorophyll and carotenoids at different patches of the lake at different times of the year.

The best time to visit this place would thus be the summer season!

Bizarre Creature – The Tongue Eating Parasite

By Anupum Pant

Background

Firstly, if you are eating something, or you are weak at heart, then go away. It isn’t going to be a pleasant one today because we are going to look at a really bizarre, and probably one of the most grossest creature ever – The tongue eating parasite.

Not that it is really needed here, but in case someone comes searching for it, the scientific name of this isopod is Cymothoa Exigua. It is one of those very large group of animals that includes crabs and lobster – called Crustacean. This one lives in the ocean and is parasitic. That means this creature lives and benefits at the expense of the other, called the host (fish in this case).

Changing Sex

Protandry hermaphroditism: Another interesting thing about these isopods is that the adult males can turn themselves into females. When a creature changes sex from male to female, it is called Protandry. This changing of sex at some point in life is called Sequential hermaphroditism. So, the tongue eating parasite is a Protandric Hermaphrodite. But that isn’t even what we came here for…The main tongue eating part is coming…

The Life of Cymothoa Exigua

The life cycle of this parasite starts with these little ones attaching themselves to gills of, say a Snapper(or others). They enter the body of a fish through gills. When they mature inside, all of them are males. Later, since they are Protandric Hermaphrodites, one of these matured males turns into a female. During this time the males are still attached to the gill arches.

The male that turns into a female, goes to the base of the tongue of this fish and attaches itself to it. It feeds on the tongue and destroys it. Then the parasite attaches itself to the stub and starts acting as a prosthetic tongue!

If you are not in a mood to read, the woman in the video below explains it nicely.

Titin Protein – The Longest Word in English

By Anupum Pant

Background

No, I’m not talking about the fictional character Tintin. It’s Titin I’m talking about. The initial part of it is pronounced almost like Titan, but please do not confuse it with Titan.  Titin is the largest protein molecule ever discovered. Soon you’ll see why it is the largest…

Titin is the short name for an extremely massive protein molecule. The full-length scientific name of this protein molecule contains 189,819 characters and is considered (by some) as the longest word in not just English, but any language.

Others choose to not consider it a word at all. You won’t even find the full scientific name of Titin in any dictionary. According to lexicographers it is only a chemical formula, not a word. Technically, they are right. So, it is not really the longest word in English.

In that case, probably a lung disease called pneumonoultramicroscopicsilicovolcanoconiosis can be considered the largest word. There are 45 letters in it. But my history teacher once told me that floccinaucinihilipilification (meaning, the estimation of something as worthless) was the longest word in English. Well, someone needs to tell me which one it really is. Till then, I’ll consider Titin as the undefeated champion…

What is it?

Titin is a protein found in certain kind of muscle tissues. It is the thing that makes those muscles elastic. For instance, in heart muscles – that expand and contract continuously for decades, without a break. The folded nature of this huge molecule makes it act like a spring – just like a long wire can be coiled into a small spring. The full chemical formula goes like this:

C132983H211861N36149O40883S693

I won’t spam my blog with the full name, but I’ll definitely point you to it. [Full name spelled out]. If you are too lazy to go there, it starts like this:

Methionylthreonylthreonylglutaminylalrylglycylphenylalanylprolylvalylprolyylglycylarginylalanyllysylleucylthreonylglutamylleucylleu…

and ends like this:

partylaspartylleucylthreonylthrnylaspartylvalylglutaminyllysylglutamilthreonylleucylserylleucylglycylasparalaspartylserylalanylthr…

The video: It takes about 233 minutes to pronounce the full chemical name – Yes, a guy tried it out (with video cuts of course). The gentleman pronounces it on camera for you. If you care enough to watch the whole 3 and half hour-long video, you’ll see how the man grows a stubble while pronouncing it. Also, you’ll see the plant dying out. But those are only gimmicks that makes the video funny. I’d like to add that his expression in the end is priceless. You shouldn’t miss that. Here, I’ve attached it for you below:

To use up the same amount of time in a better manner, I suggest that you watch the Bill Nye vs. Ken Ham debate.

His Blood was a Powerful Snakebite Serum

By Anupum Pant

Background

Trust me, this isn’t an April Fool’s joke. Bill Haast, born in the year 1910 was one very interesting person. He was a man who was immune to the bites of some of the world’s most dangerous snakes like cobras, vipers (and others). He was the only person to have survived 3 king cobra bites. He even survived the bite from a blue krait (the snake died). Not just that. His blood was treated as a powerful snakebite serum. He also saved countless lives simply donating his blood. Was it a superpower of some sort?

Did you know? Venom and Poison are not the same things.

How?

Maybe you could call it that. But, the superpower did not happen spontaneously. He did it to himself. He turned himself into a human experiment (at the cost of his life) to attain this level of resistance to snake venom.

His secret: Bill Hast, bitten by snakes more than 170 times, in his time, was a man who was bitten by poisonous snakes more times than any other living man. But those were mostly accidents that happened when he handled snakes during his career with snakes, a career that lasted more than 60 years. He built antibodies in his blood by voluntarily injecting snake venom every week since 1948! When he started doing this to himself, he did not know if he’d survive.

However, the man went on to hit 100 years of healthy life. Look at how he moves around at the age of 88. (Certainly not as agile as the 86-year-old gymnast – the super grandma. No one beats that!). He died on June 15, 2010.

His job: His real occupation was to collect venom to make anti-venom serums. He owned about 10,000 snakes. He collected the venom by repeating the process thousands of time (at the same time he was kind to the snakes). For drug companies in the year 1990, he was the source for 36,000 samples of venom.

Did you know? There is a Wasp that turns a cockroach into a zombie with its venom!

The other side of it

Of course the superpower came with a cost. In the video, you can see how had gnarled, he had lost the use of couple of muscles in his hand and had scars all over. He did it all with good intentions in mind, not for the money. Bill Haast, certainly was a legend.

Disposable Paper Microscope Costs Just 50 Cents

By Anupum Pant

Background

While doing my daily rounds on the internet today, I came across this awesome piece of modern engineering – An extremely durable and disposable microscope made out of paper and very tiny ball lenses. I saw it first on a Ted talk that I’ve attached below. Ingenious I say!

What’s new?

Microscopes are no longer those sensitive, bulky and costly instruments which were used to observe tiny life forms. These engineers have changed the age-old definition of the microscope. The fold-able paper microscope or foldscope is an origami microscope that weighs just 9 grams and is designed by a Manu Prakash, a Bioengineer professor and his team from Stanford. Instead of costing thousands of dollars, this ingenious origami microscope costs less than a dollar and is set to transform the way people use microscopes.

Besides being light, cheap and foldable, the microscope is water proof, durable to the extent that it can be dropped from the top of a building without getting damaged, does not require any external power, provides a 2000x magnification, can be assembled by a first grader in ten minutes, is easy to carry and is absolutely flat! What more can we ask for!

It can even project the image of bacteria on your wall. How cool is that! I bet your lab microscopes can’t do that.

It is set to transform the lives of those billions of people living in the developing countries. The piece of engineered paper will change the speed and accessibility of medical diagnosis in the poor nations.

Material and actual cost

Well, as the heading tells you it is a 50 cent microscope, not really. It costs only a little more than that. Still, it costs lesser than a dollar – about $0.97. Here is the material cost break-up:

  • Tiny Spherical lens: $0.56
  • 3V button battery: $0.06
  • LED light: $0.21
  • and a couple of other things like tape, paper and switch: $0.14
  • Total: $0.97

Beta testing: The team is currently looking for beta-testers for Foldscope. They’ll choose 10,000 people who would test it in a variety of settings and would help them generate an open source biology/microscopy field manual. See “Ten Thousand Microscopes signup” for details.

It reminds me of

The incredible cheap microscope discussed above is new and very precise. Until recently we didn’t have that. DIYs on the internet taught us to construct (not really) not-so-accurate microscope setups at home using a laser pointer.

All you were supposed to do is point the laser pointer through a suspended drop of bacteria infested water (or other clear liquids).This is how I toyed around (I still do) with a laser pointer to see hazy pictures of possible micro-organisms:

Chocoholics Have no Fear, Chocolate Pudding Fruit is Here

By Anupum Pant

I’ve heard of all sorts of fruits. But this is something I came across just yesterday and I think it is worth mentioning. I bet you haven’t heard of it too. This fruit is called the Black Sapote (the scientific name is Diospyros digyna, in case you need it) also known as the Chocolate pudding fruit or Black persimmon.

Description: The chocolate pudding fruit or Black sapote (not related to the more common mamey sapote) is an apple sized, olive-green colored fruit found in eastern Mexico and Central America. When ripe, it turns from bright green to a lighter shade of green. At this stage it is plucked and allowed to soften for 3-6 days. After it is allowed to soften, the skin turns brownish and the fruit becomes very soft. Now, when it is cut, a smooth and silky textured brown colored chocolate like pulp is obtained from the inside.

Although Black Sapote is slightly larger, It looks a lot similar to the apple like fruit that grows in the world’s most dangerous tree.

Taste and Recipes: Not that I’ve eaten it. Still it is interesting to know that the fruit might or might not have seeds, is delicious and tastes very close to chocolate pudding. The texture is free from any gains and feels smooth in the mouth like papaya. It is often used as a substitute for chocolate in milkshakes, ice-creams, smoothies and juices to impart a creamy rich chocolate color and flavour. It is also mixed with orange juice and served with cream. Other times it is mixed with wine, brandy, cinnamon and sugar.

Health and Fitness: For chocolate addicts, this fruit is actually very healthy. Mostly because it does not fatten you – it is low in fat. At the same time the fruit is pretty rich in Vitamin C. One fruit is said to normally contain four times as much as Vitamin C as an Orange! I don’t have to tell you that Oranges are known for their Vitamin C content.

I wonder why it doesn’t grow in India. The climate pretty much suits it! Or do you have it in India too?

Article In a sentence: There exists a fruit that goes by the name of Black Sapote or “chocolate pudding fruit”. It  tastes, looks and feels a lot like chocolate pudding, is actually low in fat and has about four times as much Vitamin C as an Orange. [Video]

Conan The Bacterium – The World’s Most Toughest Bacterium

I have been a big fan of Tardigrades and the Radiotrophic fungi since the day I found out about them. I’m a fan mostly because these are the kind of creatures that can survive in very different (extreme) kind of settings. For instance, Tardigrades can waddle through the vacuüm of space without getting harmed! (more in the links above).

These are Extremophiles – creatures that can survive extreme heat, cold, dehydration, acidity, or radiation. But Extremophiles have their own abilities and specialties. That means, if they are able to survive one kind of harsh condition, say extreme heat, there is a fat chance that the same organism will have the ability to survive other harsh conditions too. That is not the case with the bacteria we see today…

The badass bacteria beats Tardigrades.

A bacteria that goes by the name Deinococcus Radiodurans enters. It is the king of Extremophiles. Or, you can call it a Polyextremophile (reason below). So, to my list of the most badass creatures, I’m happy to announce that I’m adding a new creature – Conan the Bacterium or Deinococcus Radiodurans (DR).
(If you don’t get it, it is a bacteria nicknamed after the badass barbarian warrior movie – Conan the Barbarian – not after the funny guy on TV – Conan.)

This bacterium is so tough that it is listed in the Guinness Book of World Records as “the world’s toughest bacterium”.

What can it survive? Now what makes it better than Tardigrades or any other known creatures out there, is its ability to withstand all of the extreme conditions at the same time – Polyextremophile. So, if you decide to put it through all of these conditions at the same time –

Vacuum + Zero humidity + 85 degrees C temperature + 500,000 rads of radiation

– it will survive. The most amazing part – it will survive all of it easily. To give you an idea how much 500,000 rads of radiation is, human beings would get cooked (or charred) to death within seconds if they get exposed to that amount of radiation! Yet Conan the bacterium takes it all as if it was nothing, and can still go up to 1,500,000 rads. At those levels, even the molecular structure of glass begins to break down!

Habitat: No one knows where this bacterium belongs naturally. It is found anywhere and everywhere. You might find it in elephant’s dung or in the polar areas of the earth where the environment of earth closely resemble that of Mars.

DNA repair with a twist: Like most other bacteria, DR can repair its own DNA after damage due to extreme amounts of radiation. But, even here, it manages to stand out from the masses (other bacteria). Other bacteria like E.Coli can’t survive, more than two or three major DNA breaks. However, DR can keep on bringing its broken DNA to the original state over and over. And every time, it can stitch back its completely blown DNA bits, in a matter of few hours. There is still a lot to learn about how it manages to do this.

However, the mechanism it uses is certainly different and better from the way other bacteria do it. It doesn’t seem to have any DNA repair genes like other bacteria. And yet it is able to make complete repairs in the DNA with the help of a certain protein.

Data storage: In the future, if we ever wish to make extremely robust storage devices, we could probably learn to store data in this bacteria’s DNA. And then we might never lose data even in the case of a nuclear apocalypse.
