This deep-sea mystery is changing our understanding of life | Karen Lloyd 

Seeing her being so passionate about the topic made me smile, i love watching people talk about what they love!

Enthusiastic, passionate, articulate and candid! She made a fascinating TED talk!! Great one!

Whoa... Easily one of the best TED talks I've ever come across. Amazing content and she absolutely nailed it. Bravo lady.

Her passion for her work is truly admirable. Awesome talk.

Everyone would like to have a sympathetic biology teacher like her. How many things we still need to discover about this extraordinary planet that hosts us is that it allows us to live. Many thanks to TED thanks to those who translate these meetings.🙏👏👏👏❤️

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

"Time to get up!!!" "Just five more centuries, mom." "That's what you said five centuries ago!"

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.

Great speaker . She does a fantastic at passing that enthusiasm on.

What an awesome talk by a great scientist and a great communicator!

Maybe these microbes are earth's backup drive where its keeps the data on how life works.

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!

Loved this. She genuinely ignited interest in me to study more of ocean biology. She's so graceful and articulate

I love how she loves what she does so much. I also love her dress

I love how enthusiastic she is! What a great presentation!

I love when Karen Lloyd teach or explain something, because nobody can do better with the pasión and time that she puts in it.

This woman's speech succinctly sums up everything I love about the scientific method.

Very well done. She is an interesting and dynamic speaker. I was fascinated.

Wow this lady is perfect! Passionate, intelligent, dedicated, positive, great at speaking and just straight up beautiful. Great talk! More of these kinds of talks please!!

she speaks so well. it was a pleasure to hear her talk about her very interesting work

This blew my mind! Now I know why she can't stop thinking about it.

One of the best TED talks.

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! 😊

she is a true teacher ... transmitting her enthusiasm and her energy ... inspiring us to learn.

One of the best presentations I’ve seen this year.

I like her sm ! She's so intelligent and charming

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

Her enthusiasm is so contagious! Great talk!

another brilliant addition to TED

Wow. What an amazing, twist and turn of insights, leading to a ponderous self reflection... Bravo!

I’m sitting here literally tearing up because I think things like this are so beautiful.

Absolutely one of the best TT I've seen lately. Well done

The most clearly explained subject about something I never thought I'd hear.

I like how genuinely excited she is about it :D

She was remarkable! What joy and talent! I so enjoyed this!!

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.

Intelligent, beautiful & charismatic thanks TED this one is a winner!

Outstanding, prominent, conspicuous!! Thank you so much for your notable speech:)

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.

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.

this is TED so many used to love

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!

This woman is so amazing I LOVE her passion!! So articulate and inspiring ✨✊

This was and in fact is the most interesting talk about "tiny little microbes" i ever heared in my life. Thank you so much.

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! :-)

Very interesting

Best TED talk ever, a great example of science communication, her passion is infectious!

Fantastic speaker. Great energy. Draws the listener in. Wonderful .

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.

Thank you Ted Talks and Karen Lloyd for a truly fascinating presentation.

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

Great talk, she's very articulate and her enthusiasm is clearly genuine. I hope she does talks at elementary school levels; inspire those kids!

Amazing! What a wonderful, paradigm-shifting talk! This give me a lot to think about...

Okay the oceans are super cool

I LOVE TEACHERS LIKE HER SHE IS AMAAAAZZZINGG!!!

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. ;-)

thanks RU-vid from the bottom of my heart to recommended me this videos...I am a freak of misteries/space an so!!!

Wow this is actually incredible, I just wanna hear more.

5 seconds in...Her enthusiasm is inspiring and super endearing!

What a great speaker! And so passionate about the topic. Well done young lady.

She's a great speaker! Kept me engaged the whole time.

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.

Passion is so important and we are learning so much about us self as we apparently all are related

love her energy!

Amazing information. Unbelievable. And, great natural speaker, simple presentation with maximum concentration on her words. Very likeable

Good way to store data if you can program them.

I could listen to her over and over and over and over again. She's dynamic.

Karen does such a wonderful job, conveying the fascination of this oddball life-form.

great video again

Brilliant speaker, both funny and informative. She has certainly sparked my interest in the subject

So excited, so passionate with an enthusiasm we all should want. Thanks.Great talk.

She did a good job of making a complex subject easily understood for us common folk….❤️❤️❤️

Greatest talk and topic in years. Absolute mind shifting perspective. We appear to be a species, developed from slowly adapted micro-organisms that got used to the pulse/beat of sunlight. From one single cell to a specialized breed, ready to extinct again. And waiting after that - for millions of years - for another deep-see-organism to give it a new try :)

Fantastic talk. But if these bacteria grow that much slower than the ones we knew before, doesn't that mean they have had less generations to change their genomes? So basically they should be very behind in evolution, so can't we get information about early cells?

What an incredible person... so intelligent, passionate, charming, and funny!

Wonderful, passionate speaker, fascinating topic, new material. This is what science is all about. Bravo!

Thank you for a interesting presentation Karen Lloyd, showing us that life allways find a way. :-) You mentioned that noone to date has been able to grow the microorganisms you found in a lab and I was waiting for you to mention one component we humans often take for granted. But you didn´t. So I´m curious.. You mention that the Joides Resolution can drill thousands of meters underneath the ocean, and you use the terms deep sub surface microbes. I don´t know what depths that indicate, I just guess it´s really deep, so; won´t the pressure at that depth be massive? Maybe the microbes need that pressure in the lab too, if it´s possible to make there? Kind regards and thanks again :-) -a-

Does this mean that the more time I spend in doors the longer I will live? Or is the adapatation to this cycle long ingrained into our genetics and one lifespan is irrelevant to a change. Honest question since I've heard sun exposure helps prolong life.

Great to hear someone who really knows what she's talking about! Fascinating video.

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!

I hate the beach with a lot of heart, because of the heat, sand on my body and etc. BUT THE OCEAN IS AMAZING

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.

i love how excited she is

Absolutely brilliant presentation of a fascinating subject - wow!!!

Thanks very good

I absolutely love these lectures

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@

Excellent!! Really fascinating! One of the best TED Talks to date.

Maybe the petri dishes need to be under several hundred atmospheres of pressure to simulate the conditions that the microbes exist in.

Extremely interesting talk. I'm curious how the microbes in Lake Baikal's sediment compares.

Thank You, Karen Lloyd, for helping us to understand the significance of these microbes. Very interesting. Love & Peace to All

A beautiful and informative lecture Karen, thank you.

She deserved applause at discovering the ecosystem underneath the deep sea. The crowd was mum.

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.

So exciting!! And I love her enthusiasm!

Karen, your personality just made marine biology interesting and fun to learn about! thank you!

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.

"So in my job on a daily basis, I get to produce scientific evidence against existential loneliness" Thank you.

Karen Lloyd ... you inspire us more and more

Fascinating, brilliant delivery
