- How deep into the Earth can we go and still find life? Marine microbiologist Karen Lloyd introduces us to deep-subsurface microbes: tiny organisms that live buried meters deep in ocean mud and have been on Earth since way before animals. Learn more about these mysterious microbes, which refuse to grow in the lab and seem to have a fundamentally different relationship with time and energy than we do.

Whoa... Easily one of the best TED talks I've ever come across. Amazing content and she absolutely nailed it. Bravo lady.
Agreed!
came here to say the same. Extremely enthralling!
@@TheCapsulateIon Me too.
This is probably one of my favorite TED talks ever there was so much about microbes I found fascinating and the way she hooked me to keep on listening was so cool! This is why I absolutely love biology
Great speaker . She does a fantastic at passing that enthusiasm on.
I couldn't agree more.
Jack Northrup i came to the comments just to point that out.
Hmm not enuf spontaneous but very well prepared and executed
job
She got me exited about deep ocean mud for 13 minutes.
I’m nowhere near the level of knowledge of this lady, but I’m blown away by her ability to break it down for the horribly uneducated, like myself. Fascinating, enthusiastic and a great communicator. More please!
I love seeing a TED speaker who isn't awkward or nervous, or at least handles it well. A lot of the speakers on TED Talks are scientists/specialists in their particular field, and often don't do well with public speaking. So when they get on the stage and really capture people's attention, it's really an enjoyable experience.
"Time to get up!!!"
"Just five more centuries, mom."
"That's what you said five centuries ago!"
😂😂😂👍
No cures , Only more defanition of term ....remember though people / or humans or those still in the dish ... lifes still living in it!
Movie! Jason mask making . The it madenella effecting memories and thoughts?
I got an out side hub watching u too! Cc
That other microbe hit me over the head, and took my wallet,, and ran off. Can you give us a description? He did it all within a 1000 years. I didnt get a good look at him because it happened so fast.
What an awesome talk by a great scientist and a great communicator!
I completely agree it’s the total opposite of watching Bill Nye
She is way better looking than Bill Nye
Guys, the fundamental ability of a good communicator is listening and understanding.
But she is a brilliant speaker.
Maybe these microbes are earth's backup drive where its keeps the data on how life works.
Earth's testicles?
You are trying giving evolution human like intentionality.
@@peterbartley9155 question, how did such a diverse range of species evolve to form a correspondingly complex ecosystem given that their processes work so slowly?
@DAVID FILER always the magic answer - time. Since we have a common ancestor life originated here or there and transitioned across totally dissimilar ecosystems to take totally different forms. They do nothing when brought up here and we would die instantly without life support to go down there. Any life form that wasn't totally suited to the two different environments could never make the transition no matter how much time.
@Mark Gramm, time and evolution.
It’s never been easier in this age of information to move out of the Middle Ages.
This woman's speech succinctly sums up everything I love about the scientific method.
I love when Karen Lloyd teach or explain something, because nobody can do better with the pasión and time that she puts in it.
I love how she loves what she does so much.
I also love her dress
I can watch damn near anything if the person delivering it clearly has a passion for it. This talk affects my life 0% but I still enjoyed it. Bonus fries that I'm now in love.
I’m sitting here literally tearing up because I think things like this are so beautiful.
Brava, Karen!
Only an echo of what many others are saying-Karen is a wonderful speaker, and her passion for her subject radiates an infectious zeal. I want to know more about microbes, time, and MUD! 😊
Very well done. She is an interesting and dynamic speaker. I was fascinated.
Excellent job. Just the kind of speaker one would want at a conference. She was humorous, articulate, enthusiastic, and knowledgeable. I'm sharing the video with others.
This blew my mind! Now I know why she can't stop thinking about it.
You're hott!
Especially when she mentioned things in her throat!!!
True. Infinite knowledge, sometimes beyond mind
The most clearly explained subject about something I never thought I'd hear.
I like her sm ! She's so intelligent and charming
Love the passion. Definitely made it more interesting to watch and learn. And it never ceases to amaze me what discoveries we still have yet to make on our own planet. Things move at different rates of time relative to our own perceptions. Very fascinating.
this is TED so many used to love
And still loves :)
We don't like pedophilia.
Juanchi Cruz Yes you do, you're amongst friends. No need to be coy.
Karen, I love the way you are passionate about your work. It's contagious. Wish you more of such great discoveries to fuel your enthusiasm!

One of the best TED talks.
Very cool! Changing understanding of life, yes. Also standing out here is 'changing perception of time'. A while back, i'd gotten interested in taking a pretty deep look into time and wound up writing a short paper on it, more philosophy than physics, with a key consideration being the nature of our perception of time making things very difficult when it comes to trying to reach any understanding of 'what is time'. There was one paper another person had written, more from a scientific perspective, a guy by the name of Rovelli, paper was titled "Forget Time" (i see he's been thinking about this ever since and has recently come out with a book on it). He advocated replacing time with thermodynamic equations (something tells me that would be a hard sell to the general public). Your consideration of the amount of energy consumption/metabolic rate/longevity, with your deep see microbes (oh, temperature/metabolic rate, what's the temperature at the bottom of the ocean? i've heard that methane freezes down there...), would seem to support his argument. Certainly our perception of time is profoundly impacted by thermodynamic factors. We don't actually measure time but state variations compared to other state variations in time and it is the rate of variation we call 'time'. As you have noticed, the slower the rate of state variations, the less meaningful any concept of 'time' becomes.
i've added your talk to my continuing collection of notes on the subject of 'time'. Thanks! :-)
As a geologist, I can see the "paradigm change" needed here. Not caring about the sun, or petri dishes, is a great clue. Thanks Prof. Lloyd
Maybe the petri dishes need to be under several hundred atmospheres of pressure to simulate the conditions that the microbes exist in.
Kevin Deemster ideas worth spreading
I'm sure they would have thought of that being micro biologists
Yep, that would be very hard to reproduce.
My very first thought. She and her colleagues are probably right about the time issue - but, still...
no I don' think this is hard to reproduce. there are pressure chambers existing that can mimic pretty high pressures already. these are used for industrial diving in off-shore environments. it's called saturation diving.
I could listen to her over and over and over and over again. She's dynamic.
Okay the oceans are super cool
Wow. What an amazing, twist and turn of insights, leading to a ponderous self reflection... Bravo!
I love how we search endlessly into space for life, justify budgets that could instead be used feed those starving and yet have only explored but a fraction of our oceans - which could lead us to understanding ourselves, as well as all forms of life. Thank you for your research! We need more Karens like you.
She did an excellent job , she is able do condense such a huge amount of information into a few minutes and make it interesting and
understandable , amazing to find life in such impossible conditions, kind of spooky.
I like how genuinely excited she is about it :D
Amazing information. Unbelievable. And, great natural speaker, simple presentation with maximum concentration on her words. Very likeable
If we could learn how to temporarily slow metabolism to this minimalistic state, it could also solve long distance space travel issues. Instead of trying to work out the issues of low temperatures, we could just take some deep sea tech to deep space.
The spellbound audience speaks to the passion of the presenter. Fascinating topic delivered by a master.
"So in my job on a daily basis, I get to produce scientific evidence against existential loneliness" Thank you.
Passion is so important and we are learning so much about us self as we apparently all are related
she is a true teacher ... transmitting her enthusiasm and her energy ... inspiring us to learn.
Intelligent, beautiful & charismatic thanks TED this one is a winner!
Its wonderful to see someone who can engage you for an entire talk on a subject not many would go, oh I will watch this. Big respect for person.
Well done
She deserved applause at discovering the ecosystem underneath the deep sea. The crowd was mum.
This info is amazing. Just so fascinating to think that organisms exist in ways we think are impossible
👋i hope you're safe over there? I hope this year brings happiness prosperity love and peace 💞❤️🕊️🕊️ all over the world! Happy New year 🎆 🙏🌍
I'm originally from Canada currently living in California ☀️☀️☀️and you where are you from if i may ask?
She's a great speaker! Kept me engaged the whole time.
This was and in fact is the most interesting talk about "tiny little microbes" i ever heared in my life. Thank you so much.
Good way to store data if you can program them.
And duplicate them. It's not convenient economically to get the "bits" only from the ocean floor
Fantastic speaker. Great energy. Draws the listener in. Wonderful .
Brilliant speaker, both funny and informative. She has certainly sparked my interest in the subject
It's so fastinating!!
There are myriads of microbes in deep-subsurface, surviving without food and sunlight.
They even refuse to grow in the laboratory because their time concept and energy system are totally different with humans. They have different time zones with humans, which is the only thing human cannot control. I could realize that time is uncontrollable and precious even watching the ted related with microbiomes.
love her energy!
“Scientific evidence against existential loneliness”.. NICE!
You just fell for that. She basically said you were not as important as a one-celled organism.. please don't believe anything this lady says
We're born knowing this.
I've always possesed this understanding.
I didn't listen at school to me it was and still is rubbish and lies
@@nemonemo3898 pfft pathetic.

Absolutely one of the best TT I've seen lately. Well done
Extremely interesting talk. I'm curious how the microbes in Lake Baikal's sediment compares.
CJ Calhoun Ha, a shout out to Lake Baikal, wasn’t expecting that. Interesting to me because I was reading about Baikal last week, apparently I had family that lived very close to the ancient lake
Now I go looking for this lake's information... This is how I get stuck in RUclips algorithms and keep putting off doing my school work. I'm not complaining at all. 😄
CJ Calhoun - Interesting thought, Baikal's fresh water though and only a mile deep- would that have an effect? Or would deep sediment nullify that? Ask her before Baikal gets more polluted. Imagine telling your microbes "you have relatives in Russia".
@@haroldwilkes6608 it's still a relatively isolated environment, I don't know how well studied microbial life is there but I'd imagine given the massive diversity in the microbial world that there is plenty unlike anything we've seen, it makes these kinds of environments extremely interesting to microbiologists looking for both novel antimicrobial metabolites and novel strategies.
@@rtendotapiwa306 Glad to know there's somebody else like me - I read something, have a minor question, end up with two lost days on the internet and another in a university library, have to look at my phone to find out what day it is. And have completely forgotten what my original question was. Have fun but don't put off the homework too long. I'm retired so no school work to do.
As Jack Northrup said below, Karen passes on her enthusiasm to us all. It's great to know people who are so jazzed about science - it gives me hope!
Amazing! What a wonderful, paradigm-shifting talk! This give me a lot to think about...
I find this fascinating on multiple levels. Not only does it speak to the potential diversity of ways that life has adapted to survive on our own planet, but it absolutely informs, if not redefines, our thinking about the search for life on other worlds. If one was to extrapolate Karen's explanation/description of the sun as the source of energy and also the means by which more-familiar-to-us life was sped up in a sense, then we can view both ourselves and the deep under-surface microbial life on a continuum of sorts. If then we are on that continuum, what about other forms of life which may have adapted and grown to function in a difference range of that continuum, in the vast, vast plenitude between us and them? But here's the fascinating part: What about what WE might term as 'intelligent' life that has evolved somewhere else on that continuum? Maybe in between, or possibly even beyond us? What about a life form that's intelligent but has evolved in their world so that their biorhythms are quite faster than the sedimentary microbes, but still far less frequent than our own? Like looking at the hour-hand of a clock, their movements, signals, and processes might be imperceptible to our detection. (Anyone seen Drax around here?) What about an intelligent form of life that has evolved in an environment and world where their biorhythms are far, far beyond us on the continuum? Would this life *seem* to us not only frenetic, but so frenetic and chaotic that we would interpret it as random? There are multi-faceted discussions all the time, by folks far more intelligent than I, as to what constitutes life , as well as what constitutes sentient life. In our lifetimes we have seen this conversation expand to include artificial life and intelligence. This talk by Karen, to me, adds a whole new aspect if not dimension to that discussion. Maybe this is not a new thought at all, just new to me. ;-)
Speculation is underrated, it is the heart of science

There are different kinds of speakers, and she belongs to that special club we identify as amazing, grabs our attention, presents clearly, times well, exudes confidence and enthusiasm.
I hate the beach with a lot of heart, because of the heat, sand on my body and etc. BUT THE OCEAN IS AMAZING
ChisCrisKris hello Anakin
i wish that was it, but there is alot of fecal matter in the beaches around here (galveston).
Sand. It's coarse and rough and irritating and it gets everywhere.
Chris Chris Kris....go to Wellfleet Massachusetts..Marconi Beach is fascinating
bin
Life defies entropy by maintaining an energy gradient. These critters are living on the razor edge of life.
I heard in another talk that the higher up you are the more time you have to do stuff. It’s like your head is older than your feet. So the deeper we go, the shorter our life or the quicker we die!
I like how you can see the love and passion in her face and body language for her profession and field of study. Really good speaker.
Best TED talk ever, a great example of science communication, her passion is infectious!
9:44 "Hi my name is Justin!
My mom helped me attach my ipad to my shirt" :D
Ivana Tinkle lol.. I had to go back and look..haha how did I miss that and why is he wearing an iPad necklace? Bringing back flava flaves clock necklaces just iPad instead of clock?? Lmao! 😂
You guys are geniuses...
Those are laminated cards attached to lanyards. Look at the people to the right of him, they are also wearing them.
we need to understand Time.. ( Kala in sanskrit). It controls the energy conversions, spirituality and all existence of numerous life mechanisms around us. Rugveda has given some details regarding tile and space relationship. More detail study is very important.
I'd like to add one more speculation. How about suspended animation. Since it appears we will not be traveling at FTL speeds anytime soon, maybe we could use this knowledge to shut ourselves down for 1000 year space journey's.
nice one
I immediately thought of this as well!
If you look at it another way though, it shows how far we are from FTL lol
Wow... That would be so GREAT
What a genius idea! I’ve heard scientists talk about how suspended animation is silly and not likely but this is a pretty cool idea
It wouldn't be "shutting down" we would be "speeding up" travel to the stars. 1000 years of travel would seem to be a day.
I like her enthusiasm. She would encourage many people to get their PhDs in microbiology
Fantastic talk. I really do wish YT would make it that you have to leave a comment if you down vote a video.....always interested in knowing the reasons why people down vote.
ronaldov09 We dont need anymore dumbfounded comments on YT from such ppl. Just appreciate their non-existence in the threads lol
@Austin Downing Well, not liking a given topic and not liking a video are two different things. I've watched videos that held no interest for me, but the presenter did a great job of putting the video together for anyone interested in the topic, and so I never hit the dislike button on those videos.
The way I see it, "dislike" is for when you thought the video was utter crap *and* that the title of the video wasn't enough to convey to you that such a video simply isn't up your alley.
For example, I couldn't care less what any given celebrity is up to. If there's a video called "What [pick a celebrity] Has Been Up To Since [pick some movie or something like that)]," and the video does a good job of summarizing what's been happening for that celebrity or whatever, then I have no reason to hit dislike on it, despite me being someone who at their very core hates watching that kind of thing.
Now, if it was the same exact situation, except the delivery / content (not topic, but *content* on that topic) was not very good/terrible - or insensitive / close-minded / ignorant - then I would hit the dislike button.
A very lovely talk, Karen
@5:31 "Scientific evidence against existential loneliness!" :D
Wonderful, passionate speaker, fascinating topic, new material. This is what science is all about. Bravo!
7:00 Maybe they won't grow because they are not under the correct pressure?
They may be able to apply pressure in the lab.
you solved it mate! and from your armchair at home with no prior experience whatsoever!
I'm absolutely positive they thought of that. As well as gas environment, etc.
Good thought, but experimental scientists know what they're doing. Most, anyway.
@@rhizome550 Very impressive, mate.
Are you telepathic?
I do not understand the topic but I have watched the whole video. I like her so much.
Nice talk. In 10 minutes, she managed to changed my previously held assumptions that I knew about life on earth.
Great talk, she's very articulate and her enthusiasm is clearly genuine. I hope she does talks at elementary school levels; inspire those kids!
We need to find a way to exploit these things, so I can live forever.

- trust me, eternal life is deja vu all over again.
Very fascinating. The whole of life on earth (or rather the web of life) is an energy and nutrient cycling - energy from the sun and nutrients from the earth. When the environment is so limited in its energy source, then life proceeds at this infinitesimally slow pace. A path breaking insight.
Life finds a way.
4 words in one of the most beautiful sentences ever made.
Other people here said this better but I love her. Smart, beautiful, fun. There's a lucky man or woman out there that gets to here this everyday. Goals.
What a great speaker! And so passionate about the topic. Well done young lady.
Very interesting not only the possible applications to our technology but also to the possibility of life in other areas of our solar system great vid
Excellent! Well presented. Interesting. Is what science is about. Best wishes to all.
So basically, these microbes are parts of the living soul of our planet :D
That's how I felt as well: The microbes are the skin of gaia earth. If the entire earth is an organism and different species are like organs, then what organ are humans?
NICE PRESENTATION.....GREAT SCIENCE...RIVETING AND AMAZING.......WOW
Can those bacteria survive in space? Could they travel between planets or different solar systems?
S if space is as calm and “boring” as the deep sea ocean floor ¯\_(ツ)_/¯ i can see that happening. i dunno though, ask the lady talking- she actually knows what she’s talking about x)
They must need some kind of energy source, like earth temperature or preassure or gravity. In deep space you have 0 K most places so nothing can live there.
Edit: I was wrong about the 0K:
« if you travel out far away from everything in the Universe, you can never get lower than a minimum of just 2.7 Kelvin or -270.45 Celsius.
This is the temperature of the cosmic microwave background radiation, which permeates the entire Universe»
So, as these microbes requires only a zeptowatt of power they could survive!
No idea, and Im not sure if we can actually tell whether these bacteria are alive or dead, if we cant make them eat nutrients or grow on human timescales? That said, they would need to be able to survive radiation and charged particle bombardments of space. Being protected by oceans of water, they wont be used to that.
I suspect that they can survive but not live. Anf that they're not the only ones. Especially but not only if they're frozen. Or if they can generate endospores.
But if that's what you're asking, I don't know if they have a better chance of being the "starter kit for life export" if such a thing exists. From what I understand they "don't die" under high pressure anaerobic conditions, so that's an asset for a starter kit. But hey, who knows where first life all came from? It may as well be here. You're implying an orthogenesis context but yet your are not seeking an answer to the interesting questions. You're trying to delay them. You ask why and you wonder how. In other word, the hypothesis that life can propagate through space doesn't tell us why life has started. Life stays a statistical miracle even if it has started elsewhere.
S
There are bacteria that can survive in vacuum and other that can live in nuclear reactors, so to answer your question, yes. The relevant theory is called panspermia
People who are excited about their fields are infectious :-) They get so fired up about their... thing, they just drag you along. Those are the people who make great elementary school visiting speakers. The kids might not follow in the speaker's footsteps, but they'll remember how they felt and maybe lean in the direction of curiosity. Maybe later in life it'll spur them to take up a challenging major in a field that fascinates them. Something other than Marketing, Advertising or Communications.
I care about your petri dishes!
But you're not a microbe so she doesn't care about you, sadly.
Fried eggs.
Excellent!! Really fascinating! One of the best TED Talks to date.
I did enjoy her presentation and energetic communication.
I love the interesting challenge that is always thrown in our faces by the TED bits. great work at keeping us all stimulated mentally
cheers@
I'm just a dead president, but, If these microbes came off the ocean floor where pressure is incredibly high, wouldn't they need that pressure to propagate??? Would they not be genetically pre-disposed to that environment??
@Abe Lincoln if that were the case they would've been killed before they were ever studied. I'm pretty sure the microbiologists have thought up everything that casual viewers are positing in the comments :D
@@SpydersByte Technically this is one of the beauties of the internet. So many brains on one subject is hard to beat.
@@toukyoumasters3494 And therefore, I consider the so called overpopulation of planet earth a good chance, too. In a few years, we will have 8 billion unique brains, in a much higher state of connection than ever before. How cool!
Food, basic insurance for catastrophic events, free education and freedom from wars for every earth citizen. I guess and believe this would be possible today.
@@SpydersByte Not really. There have been many discoveries founded on the internet, which scientists did not imagine.
@@etheriondesigns that's not really what I said is it? Just saying if the casual viewer can imagine something in the comments it's pretty damn likely the professionals *also* had that thought.
Wow amazing. I thought I knew everything. And what a great lecturer.
i fall in love ...
And we think we know so much already... Dunning-Kruger effect... when you are at the forefront of such discoveries, it's like impossible not to be as enthusiastic as she is...
maybe these things only start existing when we start looking fo them
