The Ghost Viruses Hiding In Your DNA 

The attention to detail in some of the side jokes are stunning

You are my new vsauce.

Anyone else notice the increasing number of stethoscopes? Hahaha! 😂

"Where single cells meet" How can such an informative Video simultaneously be so goddamn hilarious?

This guy's ability to remain informative while making unexpected jokes should be transferred to other people's DNA.

I really like the humor you sneak in. This channel will definitely blow up soon. Millions of subs incoming. Keep it up! Cheers!

I love that fake thumbnail at the end, it’s brilliant.

The stethoscopes made me giggle. =D So dang funny.

I don't know how I originally found this channel... but this is one of the few I thoroughly look forward to and enjoy every single post, you're awesome man!

“We will be landing in Heathrow plane station shortly”

The joke is that Alu means Potato in Hindi.

"Power Stations of the cell" I knew this day would come. *We're Breaking the conditioning! Raaaaaaa!!!*

I'm starting to see how important people like Tom Scott are. Who knows if I would have ever found this channel without Tom's "guest video system". What I'm trying to say is: I love your videos.

I'm _74%_ sure my pseudogenes are made up of mangled Toyota Corollas. My body couldn't afford a Lamborghini.

Many thanks to Tom Scott for introducing me to this wonderfully brilliant gentleman

One of the most important lessons I've learned from watching MedLife Crisis videos: Never see them drinking liquids due to the risk of expulsion through the nose because of laughter. Keep the good work Doctor!

Fun fact : the original airports were actual ports, on the water, because the original commercial airplanes were seaplanes that take off and land on water, not a runway. Thats why we have airports and not plane stations.

always fascinating, educational and hysterical. Thank you again!

Whew. *"Playstation"* would've killed me. Glad it stopped at Planehouse.

I'm personally interested in the CYP 2D6 gene and all it's little foibles. In about 7% of white people it's somehow got nerfed and no longer produces Cytochrome P450 2D6 which is one cause for oral forms of drugs not being metabolised into the active form. In indigenous Chinese people that percentage is vastly reduced (to almost zero according to one study) and in people of African descent it's (depending on sources) about 1%. It's also for some reason way more common to be not expressed in white people with Asperger's (25% to 35% dependant on study). Why this issue is far more common in people with Asperger's is not currently understood as far as I know. IE there is definite correlation but there is no proven causality.

Wow...... need a rest now! Brilliant!

How could you dislike virology? Viruses are awesome man! Other than the whole killing part. And frankly, it's kind of weird to think that we're basically the result of millions of organisms that decided to cooperate together. Also, South Park already predicted how we will react to pig organs: ManBearPig. Another great episode!

Great video! Maybe you should've mentioned how ERVs are silenced in ES cells. It's one of the key unique features of ESC and the core reason why a child born to a retrovirus infected mother will often silence the viral expression through methylation of recognised viral elements.

2:25 Reactivating ERV - the researchers name was John coffin

Just watched all your videos. Absolutely brilliant!

this was super duper interesting. thoroughly enjoyed it. well worth my 8 minutes 😊 Thank you Tom Scott for turning me on to this channel!

Excellently informative video. A bit surprising that you didn't touch on the fact that viruses can be used to treat disease (the enemy of our enemy can be our friend). Virus therapy (phage therapy) to treat bacterial infections. You did touch on the fact that viruses are a mixed bag. Viruses undoubtedly naturally help keep other human pathogens at bay through happenstance.

YEAH LEARNING! WOO! Need to send this to my little brother actually; he'd be fascinated.

First of all the facts in this video blew me away. This last bit is also somewhat good news. If radiation hits our genome it means there is a 50% chance it hits a broken lamborgini fragment. That makes me wonder though: When junk DNA gets damaged by outside factors, will the cell try to "repair" it the same way it repairs useful DNA?

0:48 yes, bioinframatica major. Viruses are completly fascinating.

A year after and this video is even more relevant

"your genome is a wasteland of crashed Lamborghini's, selfish parasites and dead virusses" ah the beauty of life!

Anybody rewatching this after coronavirus outbreak? Quality content for Argentina's quarantine

that moment when you cant see the number because you are red-green colourblind 🤔

So glad I came across this channel

an exceedingly motivating medicine lesson

As always - amazing content! Thanks!

Power plant?

Viruses are fascinating. Phages for example can be used to kill specific types of bacteria without harming anything else.

Put this on your dating profile: My genome is a wasteland full of crashed Lamborghinis, selfish parasites & dead viruses :D

This video makes me understand how special being a human is... we literally won the evolutionary lottery.

Talking about viruses, in my opinion the question whether viruses are alive or not is not something we need to discover, but instead we have to decide the answer, by giving a universal definition to 'life`. I personally like the one used by nasa in search of extraterrestrial life: "a self-sustaining chemical system capable of Darwinian evolution".. Its broad but I think it's only fair, with it viruses would definitely be considered life forms

I knew from the title this is gonna be about retroviruses. I've just read up on this, let's hecking go.

What a great video. The only problem now is that I have to go do some research on the parts I didn't understand. Sigh. But I did get most of it except a bit of the chemistry so I am sure I'll be able whiz through it the next time going "Yup, yup, I got that".

I'm currently studying the human herpesvirus 6 (HHV-6) for my master's thesis. It's a virus that integrates its DNA into host telomeres. Occasionally it's possible for the virus to infect germ cells which can lead to children who carry the viral genome in every nucleated cell of their body. Pretty fascinating stuff. Thanks for the great video!

People are worried about GMOs, but our genome's already a mess.

Facinating. i wonder if one day humanity will simply become unviabale due to signal to noise ratio in the DNA becoming so low we just can't rerplicate a working body

You are very good and funny. Very interesting videos, keep em coming

I' going to joing your rant about terminology. I liked the usage of aloo for alu. Unfortunately aloo has a long A as in "ahloo" which I remember from an ambulant veg seller who cried his wares round the streets of Delhi where I lived as a child, ending his call always with an extended "alooooooo" or a rising note, which doesn't work quite so well with a short initial A.

Litmann review incoming!!!

The DNA sections that replicate themselves along DNA sound like SCP infohazards.

Ooo this one's got scary music at the end

Great reference to GitS!

Your videos rocks. I watch you on my lunch breaks.

That alu joke took me a second, but I do love a good aloo mutter.

This shit is cash my man, fun and informative.

When we call it the Powerhouse of the cell, we're actually referring to the famous song Powerhouse, by the Raymond Scott Quintet. Because everyone loves Looney Tunes!

I can’t believe someone’s actually talking about ERVs

"The powerstation", hey fellas, "The powerstation". Well, ooh la de da, Mr. French man. Well, what do you call it? "The powerhouse"

so no mention of the viral origin of the placenta... always thought that was the most rad one.

Who knew that Stallone had a deep understanding of the human genome, as far back as the 80's?!

Loving this

Great video, as always! Discovered this channel a few days ago and it has quickly become one of my favorite. PS: Mind linking the intro / outro music?

Amazing job, really amazing!

Power station must be a British term, Americans tend to use power plant.

Great video. I need to buy a pair of Alu's jeans.

The mitochondria living inside us is like force in the star wars.

1. your videos are interesting and entertaining at the same time. Were you ever told you look frighteningly similar to "the wood whisperer" youtuber?

As a programmer, I'm not surprised that half of my genetic code is //deprecated

This'll be viral.

Well biology is definitely now my favourite subject

Our DNA is like the hard drive of a child’s computer.

That's one way to make sure you don't lose your stethoscope.

"dozens of horrible ways to die in exchange for being able to see this number" ...Im colorblind goddamn it I got nothing

I'm still with Darkk Mane on this one...."THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL!!!"

Please do a video about heart palpitations!

My mad-scientist side cackled throughout this whole video :)

Very enjoyable video

that intro was vsauce-esque

Dang Rohis, I can't believe you're not using "Ghost in the Cells" in the thumbnail.

That's one sick intro!

It's so fascinating, I'm thinking that transposable elements and pseudogenes must have had a role to play in the rare creation of new functionalities in evolution...

Ghost in the shell

Woooow I love this channel!

I know very little about genetics, but it's wild to me that a gene could be incredibly similar to another gene that definitely has a function, but be completely dormant... As I understand it, genes are comprised of DNA, and there are very few building blocks for DNA, so I'd assume each combination of those blocks would have to be useful to encode the (presumably widely varying) instructions... But I guess we're talking about a lot of DNA in a single gene, and again, I know nothing about how genes translate into qualities of their organism.

3:18 What doesn't kill you makes you stronger.

I love the increase in quality and the effort put in. It's a nice change. That said.. Kinda disappointed you didn't point out the suggested benefit of having mostly "junk" dna. If only 20% of the total is important, there is an overall lower average chance of a random mutation producing lethal results. This is useful enough on earth. But in space it's been debated it might give us one hell of a radiation exposure tolerance. There's plenty of benefits to this wasteland, it's not just junk without it or race could face serious issues!

Well this aged interestingly

Did RU-vid remove the "ventilator disconnection prank" video? I saw it on the end screen but I can't click it and I can't find it on RU-vid anywhere!!

Ahhhh. I have leg day tomorrow. You had to remind me! Grr.

We call it a power plant here in the states.

You CAN call a fire station a fire house though

PERVs 😂🤣I fully just laughed into a coughing fit that was hilarious 3:58

Anyone else thinking power plant? Is this another British/American thing? Taking the analogy of a train station then many of those other things don't make sense either. Like when people refer to "Grand central station" and it's really "Grand central terminal". A train line terminates at the two ends and has "stations" along it at which the train stops. Air, like the ocean, is a wide open fluid which you can go any direction in. Hence a plane, like a boat, pulls into a "port". "Bus station" is at least reasonably analogous in this sense. Electricity doesn't stop, but starts there, and really it is generated or produced there. A "plant" in the industrial sense makes things, none of those other stations produce anything, so power plant, take that. Wow, this comment really got off the rails.

Soo, what if we started cutting useless crap from our dna? Would that mean less copying errors due to less material in need of processing? Faster and less resource intensive cell reproduction? Are there any possible advantages? What about disadvantages (aside from cutting stuff that later on turns out to be useful after all)?

I noticed the stethoscopes from 3. Then I had to go back to check when they changed.

1:16 that's a shwarma

Planestation! That made me LOL!

Great video! I think there are also some bacteria, with virus DNA inside. So when you take antibiotics, the stresses on the bacteria cause the virus DNA to be activated, making you more ill!

That was Great !
