I just wish I had a longer lifetime (I just turned 80) because I am always discovering new things I would like to know something about, and the above subject is another! I had never heard of what she is talking about. So I was glad to find out there's a book that will try to enlighten what the lecturer was talking about.
I'm here after reading her book "The Epigenetics Revolution" to learn about possible updates in the field since it came out a few years ago. I would highly suggest the book to anyone as I had no background knowledge other than high school Biology and yet every chapter would blow me away.
The most boring presentation. Boring verbal diarrhea and the poor woman is totally confused as to the meaning of Epigenetic. What saves her is the cute accent. She is trully the product of Rockefeller education system. Sad.
@@gracegwozdz8185. Well that’s a rather pretentious comment, given that she is an expert in epigenetics. Perhaps you would care to enlighten us with your wisdom on where she went wrong?
I absolutely have to watch this again and again. She has few equals in terms of clarity and lucidity. I am going to forward this to my entire family. One of the most interesting topics explained by one of the best presenters.
I'm currently reading 'Junk DNA' and I can assure you that it is really informative and it doesn't bore you. As a first-year medical college student, it is really helpful to visualize the epigenetic differentiation. Examples she gives are hilarious.
Reading her book now after watching this a few months ago! Brilliant and exciting literature! Epigenetics is such a fascinating field! This is telling us how we can affect our future progeny!
How fortunate that I in india can access this extraordinary lecture delivered so well and generously sprinkled with humor. Great contribution to science education. Have her books which are so precious for me
Yes - but we need the right stimulus; and that can come only from the WORD of GOD, found in the Bible. We could easily deteriorate into barbarism, especially if we start copying animals, instead of reminding ourselves that we are made in the image of GOD.
The 8 proteins are histones and form a protein complex known as a histone octamer, which is spool shaped (marshmallows were used in the demonstration). The 8 proteins in the histone octamer are actually 2 copies of 4 proteins, H2A, H2B, H3 and H4. DNA wraps around the histone octamer known as a nucleosome and they form chains like beads on a string making up chromatin. A nucleosome can be defined as a small length of DNA wrapped around eight histone proteins. The key difference between chromatin and nucleosome is that chromatin is a whole structure of complex DNA and proteins while nucleosome is a basic unit of chromatin. The beads on a string make up something called euchromatin or open chromatin that is enriched in genes and active under transcription (transfer of genetic instructions) which is why it is so important in epigenetics and changes in the phenotype (physical traits- e.g. appearance).
Its all actually very simple to understand when you grasp what is actually occurring in terms of epigentics and how we are products of evolution - genetics and events - what we do and what is done to us
Finally! we have an exciting, summation of information about this field! Thank you for posting. Best explanations, clear analogies and diagrams I've ever found .I've been interested in this field for many years, though no longer a formal student. This great video brings me up to date.
Fascinating subject, i'd never heard of this subject before. Props to the lecturer for giving such an entertaining lecture on a complicated subject! I hope you have her back again.
First time i am watching her. Today I purchased her book " The Epigenetics Revolution. Not my subject. But i have interest. Happy to watch. Thank you Madam. Regards
Great video! Increasingly our behavior determines our longevity. Just as weight scales provide transparency and motivate dieting, epigenetic tests now make biological age (as distinct from chronological age) more transparent and motivate us to adopt right behaviors to help us live longer.
What a wonderful (and delicious!) lecture! I am enraptured by her humour and her passion. What a shame I am watching this 9 years after the release of the original video.
If for whatever reason molecular biology doesn't work out for Nessa Carey, she can surely do well as a stand-up comedian! Very entertaining and enlightening talk!
I scored rotten childhood, alcoholism, diabetes, 40yrs depression. My parents died 2012. I went outside and stood in the sun. Instant relief then happiness. Counselling and diagnosed as having aspergers (3yrs old emotionally top 2% computational brain). I took up Zentangling Art and I am still changing & growing. It took 20 yrs after MtDna test for me to find a living relative and I discovered that 5 gens back my ancestor came from Sweden who was a Sami. I then discovered I had inherited characteristics from that cultures but not in the same configuration. I bought a good copy of the I Ching and asked HOW I could bring information from the MtDna into my conciousness. The answer was hexagram 19. It told me not to think about it or ask another question and when I asked another question I was told to not do that again. This is simplified. The overall answer was that the answer was approaching. Sooooo... I bought a book on epigenetics, wrote to a scientist and I find your teaching style that puts the text books I am reading into context. I am 72 and am like a teenager. THANK you so much.
All I want to do right now is eat strawberry laces and jelly tots.....on a serious note, this lecture was FASCINATING - thank you Nessa for your fabulous energy teaching this
Oh no! Your exposure to the video (environmental factor) has changed your mental content, which could change your behaviour which could change your epigenetics, which could change the future of your offspring? Good grief this rabbit hole goes deep...
Her explanation about stress and childhood experiences is interesting. I was very fortunate because I had a pretty stable, happy childhood with a protective father who thought I was a piece of gold and a loving mother who was a great nurturer. Even though I was overweight and constantly bullied, I retained my happiness and confidence that has allowed me to be successful in my career and personal life. I am married to a great person, but have noticed that he is usually depressed and insecure. His sister has finally admitted that out of 6 siblings, he was given the least amount of attention and praise and was often criticized. This was needed information for me as his spouse because I can now understand why he rather that I remain overweight. When I lost most of my weight, my husband would exhibit jealousy and insecurity. He would retreat into his den, and not talk to me. Now that I have lost my mobility, my husband seems happy which I find hurtful, but with theory, I have learned that he feels empowered because he feels no one will find me attractive and he can now be the only person I can depend
Nice. But molecular genetics was already about gene expression regulation, in bacteria, at the start. Sex is a molecular dialog and it has probably many and variate levels of (self) interpretation. I have discovered computer science in the working of the DNA of Escherichia Coli, a long time ago (Jacob & Monod mainly).
The DNA code starts from the same then the coding changes but the DNA coding is all the same in the start of the code. Example is like computer coding. Code DNAMOMDAD then add on EYESLASHES or DNADADMOM Liver etc etc. It's so damn AMAZING
Wow, really enjoyed this lecture. Any sociological/psychological applications or assumptions linked to these findings? ie, poverty, oppression, consistent trauma etc...
🪄✨ Made with SummarizeYT 0:49 - The human genome sequence was first released in 2001, causing a huge hoopla. 2:03 - Epigenetic phenomena have been known for a long time but were not given much attention. 3:00 - Laboratory mice with the same genetic background can have different weights due to epigenetic factors. 5:01 - Gender in crocodiles is determined by the temperature at which the eggs develop, not genetics. 6:01 - Different cell types in our body have the same DNA code but exhibit different characteristics. 8:08 - Epigenetics plays a crucial role in gene expression and can be influenced by external factors. 12:00 - Epigenetic modifications can switch genes on and off, leading to different gene expressions. 14:00 - Epigenetic modifications can be compared to different flavors of jelly tots, introducing flexibility in gene expression. 16:15 - Epigenetic modifications can also compact DNA, permanently switching off gene expression. 17:27 - Epigenetic modifications can go wrong and contribute to diseases like cancer and diabetes. 19:01 - Children who have experienced abuse or trauma in their childhood are more likely to develop chronic diseases later in life. 20:07 - Epigenetics can influence what happens in organisms without altering the DNA sequence. 20:42 - Baby rats that are loved and cared for by their mothers have low levels of stress hormones. 22:03 - Epigenetic modifications in rats can be passed down from generation to generation. 24:01 - Epigenetic information is necessary for mammalian reproduction. 26:41 - Epigenetic changes can result in significant differences in physical characteristics, as seen in agouti mice. 30:03 - Mice can learn to associate a smell with something negative, and this fear response can be passed on to their offspring. 31:43 - Lamarck's theory of acquired characteristics is not entirely accurate, but epigenetic changes can be influenced by the environment. 34:01 - Trauma experienced by male mice can be passed on to their offspring. 35:05 - Epigenetic changes can affect the offspring's physical characteristics, as seen in the experiment with female mice. 36:03 - Identical twins can have different outcomes due to epigenetic changes.
This is EPIC!! Lamarck is partly vindicated, but that's the least of it. We are more "adjustable" than we realized before, and some of these adjustments can be passed on to the next generation. LOTS to think about, even for the ordinary person in the street who wants their offspring to be healthy and talented.
We've actually fixed this! We hope. For the last month or so, we've been making sure that the volume of the ident is less than half of what it was before. This video is slightly older so will still try to blow your eardrums out, but hopefully you won't run into this with any of our newer stuff. Do let us know if it's still too loud though.
Fantastic, Love the energy your brought to your book The Epigenetics Revolution" I wonder if you can see the link between Epigenetics and Buddhist Karma. (They are both very deep matters) Any Buddhist's out there pls read this and think....
I wonder how many people who watched this wished their jobs required them to play with candy in order to do it effectively? I think a lot of companies wouldn't be so stuffy if they allowed their workers to play with candy sometimes...
Great video! I can imagine that practical living advice can come from epigenetics, like how i can change my own in a positive way. Any chance to get that?
Hmm, for example if you don't smoke, your epigenetics for requesting more nicotin don't get switched on and your kids probably won't smoke either. Does this answer your question?
She is an amazing educator. I am grateful to be able to access high quality lecture like this for free.

Imagine the world we'd craft for ourselves if all science was communicated so brilliantly and unpretentiously. Bravo.
Daniel Holley agreed
Daniel Holley 🍷. Drink to that.
Imagine the world ww'd craft for ourselves, if we just understood that our physical reality is a collective subjection/egregore structure
The problem is that not enough people are hearing it. The communicator is not the problem
This has to be one of the most interesting presentations I've seen in a while. Absolutely fascinating.
The most boring presentation. Boring verbal diarrhea and the poor woman is totally confused as to the meaning of Epigenetic. What saves her is the cute accent. She is trully the product of Rockefeller education system. Sad.

@@Pseudify david it seems worthless showing any sort of interest in these comments since it only demonstrates her mindset..or rather choice of one.
I absolutely have to watch this again and again. She has few equals in terms of clarity and lucidity. I am going to forward this to my entire family. One of the most interesting topics explained by one of the best presenters.
Amazing lecture! She takes complicated information and breaks it down into interesting info using jokes, history, stories, movies and more! Brilliant!
I'm currently reading 'Junk DNA' and I can assure you that it is really informative and it doesn't bore you. As a first-year medical college student, it is really helpful to visualize the epigenetic differentiation. Examples she gives are hilarious.
God does not make junk. Scientists don't know it's purpose so it is automatically relegated to the junk heap.
Reading her book now after watching this a few months ago! Brilliant and exciting literature! Epigenetics is such a fascinating field! This is telling us how we can affect our future progeny!
Name of the book?
The Epigenetic Revolution by Nessa Carey@@Anonymous-zy3lh
This was the the biggest eye opener for me in the past years. This knowledge opens so many doors.
Superb presentation skills! Just the right amount of humor, story telling and information transfer to resonate with almost everyone.
Wow😂
Dude, she is a fun and exciting person to give lectures! I can listen to her talk about science all day!!!
How fortunate that I in india can access this extraordinary lecture delivered so well and generously sprinkled with humor. Great contribution to science education. Have her books which are so precious for me
Wonderful talk! I can't get enough of these Royal Institution lectures.
So much to love about this. Even all these years later rewatching it still give me all those uh-huh feelings.
SO intriguing! How the things, habits, nutrients we do now can genetically modify our future progeny!
fantastic delivery of a fantastically fascinating subject -- thoroughly enjoyable, especially being a twin myself.
You make it so easy to absorb! You're an amazing professor! Thank you!
Absolutely brilliant presentation. I just wanted to learn a little for my pathophysiology class and left amazed!
What an incredible communicator. Science needs many more with her skill.
We really need epigenetics to advance as a civilization, some might even say it's... nessacarey
Yes - but we need the right stimulus; and that can come only from the WORD of GOD, found in the Bible. We could easily deteriorate into barbarism, especially if we start copying animals, instead of reminding ourselves that we are made in the image of GOD.
Eyes Open!
Caleb Smit I see what you did there 😂😂😂👍
Amazing
Well done
This is absolutely incredible! I'm completely floored.

She destroys it. Good talk. Her book gets a bit complicated at times but this is spot on.
Her book, The Epigenetics Revolution, is fantastic by the way.
What a BRILLIANT educated and informative video, love it!

Extremely clarifying presentation, her book is also a gem of science communication...
I would very much like to hear professor Carey's view on the mRNA vaccines and their potential influence on the human epigenetics!
Fascinating, fascinating, fascinating. Absolutely fascinating.
One of the best speakers I've seen on this channel. We need more sweets-based analogies in scientific discourse.
Andri Eiríksson something with chocolate in it would be nice.
She is long-winded and boring.
Fascinating subject, i'd never heard of this subject before. Props to the lecturer for giving such an entertaining lecture on a complicated subject! I hope you have her back again.

If for whatever reason molecular biology doesn't work out for Nessa Carey, she can surely do well as a stand-up comedian! Very entertaining and enlightening talk!
Extraordinary lecture, thank you. blessings, Kimmy
Great presentation. And she's just a natural. Very entertaining. 🙂
Amazing teaching learning knowledge about the modification and genetic codes sequence of genome 🙏🙏👏👏❤️❤️💐💐
I'd love her as a professor for all my bio classes
What a great presentation. Loved it!
Such an amazing talk ma'am..really really loved it to the core...

thank you so very much. This is wonderful. I am glad to say I was wrong.
Thanks for making it easy to understand
Outstanding presentation. Very clear. Congratulations!!!!

Thank you for the very fascinating and lively lecture! I love it!
Crocodiles and Dinosaurs share a common ancestor, crocs are not descended directly from dinosaurs.
Brilliant talk, especially your dna analogies
First-rate presentation on this topic. Thanks very much.
Really good - packed with interesting insights and good for the RI to tackle what is admittedly a controversial topic.
all i can give to this lady is 🙇 Respect! amaizing
What a brilliant lady!
Great presentation 👏

Emotional abuse and neglect to keep you overweight to maintain his own well-being. Understanding his behaviour should not excuse it.
Its really a great lecture never had idea management student can enjoy science.
What a spectacular lecture!
Nice. But molecular genetics was already about gene expression regulation, in bacteria, at the start. Sex is a molecular dialog and it has probably many and variate levels of (self) interpretation.

Code DNAMOMDAD then add on EYESLASHES or DNADADMOM Liver etc etc. It's so damn AMAZING
Excellent if you do it everyday in your practice with quantum
I really enjoyed this talk thank you
excellent video to describe epigentics, its a subject i wanted to write on next for my blog.
What a great woman !
well done and entertaining presentation on the topic of epigenetics
Just wonderful! 🧬
Wow, really enjoyed this lecture. Any sociological/psychological applications or assumptions linked to these findings? ie, poverty, oppression, consistent trauma etc...

Showed this video to a friend. She responded, "it's true with exception to Mary, the mother of Jesus".
How does mitochondrial DNA affect heredity, and how can you tell?
Will be buying her book
Actually I wouldn't say it's a new field of biology but rather one we just found out about lol ... super interesting
I hope everyone enjoyed this.

I wonder if you can see the link between Epigenetics and Buddhist Karma.
(They are both very deep matters)
Any Buddhist's out there pls read this and think....
Great talk
It would be interesting to know what foods could turn on or turn off gene expression in humans and the outcome of the change.
She's great ! ❤️
