My friend hawtouse bunserbuner but bunser burner is very important because they have cooked and drinking boiled water thankyou❤❤❤❤❤❤

Like your videos❤❤🎉🎉😮

Good knowledge need to change the food practice

This is a good demo, let down only by its perpetuation of the widespread myth that a flint striker is a safer way of lighting a gas appliance than a match. The welding industry does the most to perpetuate this myth. The number of failed attempts to light the burner with the striker in this video illustrates the chief problem with strikers: their failure rate means they allow the discharge of excessive amounts of gas into the air around the operator before the burner actually catches light. I’ve also seen no evidence that strikers reduce the incidence of flashbacks - the main supposed advantage disseminated by certain sectors of the welding industry.

If the docking stations in the mitochondria are plugged up then energy can’t get into the cell to be burned

This is the best lecture I have reviewed after hundreds of hours on studying our metabolic pathways. First time I heard or read of leptin in regard to satiety. If I have only 2 hours to teach people what is happening to them in regards to hunger, satiety and nutrition, I will this one.

It is August 05, 2024 My food expenses have doubled with my need to eat a keto diet. I also must travel far and wide to find safe and nutritious foods.

Brilliant absolutely brilliant!

Audio is not clear sub title should have been given

Great video explaining this

Mineral evolution begins 12:00

That is the most expensive lab shower i have ever seen

25:00- Bad things lead to good results: oxygen is bad for everything except as the central component of the heme in warm blooded species, but it's its 'bad' high reactivity that triggered the formation of the 2/3 of minerals seen today that led to the creation of life on earth which would've been impossible otherwise. Extremely underrated vid series. Hazen's mineral lectures amazed me , and actually should've on many more other earthens who are interested in how it came into a being as it is rather than just live on it.

So I take it that this isn't the audio engineering course?

Many antibiotics target bacterial protein production, making it crucial to comprehend the process.* 13:18 🎨 *Various representations of molecules, from realistic to schematic, help convey their structures. The analogy of representing people through photographs, caricatures, or symbols is applied to molecular representations.* 15:07 🧬 *Genes contain information on making proteins. Proteins, diverse in structure and function, are built from 20 types of amino acids. Understanding protein synthesis involves decoding genetic instructions from DNA.* 19:41 🧬 *Messenger RNA (mRNA) carries genetic instructions from DNA to the ribosome, where transfer RNA (tRNA) brings specific amino acids, facilitating protein synthesis.* 22:00 🌐 *The ribosome, composed of RNA and proteins, decodes mRNA and facilitates the assembly of amino acids into proteins. The intricate process involves recognition of codons and the joining of amino acids.* 25:53 🧑‍🔬 *Electron microscopy provides a realistic image of the ribosome's structure, revealing tRNA as bent L-shaped molecules, mRNA snaking through the small subunit, and the growing protein chain emerging.* 26:21 🎓 *Venki Ramakrishnan transitioned from physics to biology due to the rapid breakthroughs in biology during the 70s, contrasting with what he perceived as slower progress in physics.* 30:00 🚚 *Venki moved to UC San Diego for two years to learn biology, taking undergraduate courses to broaden his knowledge.* 31:23 📚 *Reading a Scientific American article led Venki to biology, and he chose to pursue a PhD in the field to gain a broad understanding, even with a family to support.* 36:56 📡 *Venki discusses crystallography, the method for visualizing small structures like molecules, using X-rays and three-dimensional images generated through computer analysis.* 39:12 🏗️ *Venki, joined by Bill Clemens and John McCutchen, started working on the ribosome at Utah in the mid-'90s, aiming for the small subunit due to concerns about the large subunit's complexity.* 43:20 🌍 *Despite uncertainties and competition, Venki decided to focus on the ribosome, emphasizing the significance of stable funding and institutional support for long-term, impactful research.* 50:19 🧬 *Venki Ramakrishnan highlights the initial breakthrough in ribosome research, positioning proteins and interpreting about a third of the molecule.* 51:39 🌐 *The use of synchrotrons, high-energy accelerators, was crucial in the ribosome research race, requiring work around the clock in isolated huts to capture X-ray images.* 52:19 🧩 *Interpreting ribosome structures is like solving a complex three-dimensional jigsaw puzzle, recognizing molecular features from the X-ray images.* 53:41 🧬 *The discovery that the active sites in the ribosome are primarily composed of RNA, not proteins, provided direct proof supporting Francis Crick's idea of early ribosomes being RNA-based.* 54:48 🦠 *Antibiotics' impact on ribosomes helped understand both antibiotic mechanisms and ribosomal functions, demonstrating the dual role of antibiotics in research.* 55:30 📸 *Over 10-15 years, snapshots of the ribosome's different states were taken to comprehend its dynamic movements during protein synthesis.* 56:26 🏆 *Venki Ramakrishnan recalls receiving the Nobel Prize, initially skeptical due to a past disagreement with a Swedish colleague, highlighting unexpected career paths.* 58:53 🔄 *Electron microscopy has revolutionized ribosome research, allowing the study of diverse ribosomal complexes that crystallography couldn't achieve.* 01:05:22 🔬 *Future directions in ribosome research include understanding regulation mechanisms and unraveling the intricate process of ribosome assembly.* 01:06:55 🦠 *Antibiotic resistance involves mutations in the ribosome, alterations in ribosomal RNA, and the activation of pumps that expel antibiotics from bacterial cells.* 01:09:46 🌌 *The ribosome's endurance over billions of years suggests a co-evolution with genetic codes, making it challenging to replace this multifaceted RNA-protein machine.* 01:11:58 🧠 *Venki Ramakrishnan reflects on how his physics background indirectly aided his career, fostering a fearlessness to learn new techniques and contributing to problem-solving in ribosome research.* Made

Great introduction to burners!

Cruelty to the poor mice is just awful beyond belief and all the psychopaths laughing in the audience. God help the animals.

I absolutely loved this wide-ranging discussion of some of the most important issues of our time - thank you to all of the panelists for their honesty and thoughtful responses. Technical question - is there a way to increase the volume on the video?

i’m curious as to what the environmental effects of releasing gases produced in experiments such as nitrogen dioxide or chlorine and bromine gas untreated into the air. Especially if there are people working near the areas where the fume vents are.

A real hero I look up to him so much, he inspires me to continue studying nutrition. I hope to be even half as knowledgeable as him someday. THANK YOU DR LUSTIG

The way she went inside and danced

Haven is awesome. I’ve read a couple of his books and watched his course from The Teaching Company. Changed my view on the mineral evolution. Thank you Mr Hazen

So we as a civilization are gonna map out the whole universe but won't see the tiny 1 mile Rock coming for us

Congratulations Toto, Lourdes, et al...so proud of you all!!! Yay UP Chem...! Lucille Ople Guevarra

I praise First Lady Michelle Obama, her effort to bring fresh food knowledge and access to young people, as well as the importance of exercise, is extraordinary !! President Barack Obama, First Lady Michelle, accomplished much for American people's health & fitness! 🇺🇸

Maybe it's time to start accepting GMO, e.g. oxalate oxidase genetic modified American Chestnut.

What about dipping it into the sun to smelt it?

The comment about how the government keeps us focused on chronic illnesses (today it’s the flu in all its variants!!!) so the lies about food won’t be addressed. This talk is SO … 2021-2022!!!!! It’s NOT covid that’s sickening our children and prolonging our illnesses and deaths GLOBALLY. There’s not enough GDP on the planet to afford the mess we’re in.

My wife and I are watching after the fact from Arizona. Thanks for doing this every year!

This great lecture answered a question for me regarding fructose . I couldn't understand how one type of sugar - sucrose - was being metabolised in a completely different way from another - fructose !? It is obviously an evolutionary development that allows the bounty of fruit in late summer to be utilizised rapidly for fat storage prior to winter with its calorie shortages , or for hibernation . In nature this is a beautiful adaptation , but when fructose is available in the diet all year around and more dangerously found as fructose syrup in commonly eaten processed foods , then this adaptation becomes very dangerous . Thank you Dr Lustig .

This was wrong then and it is wrong now!

Commenting for algorithm

Excellent! Do you have sources for the Early Carbon Cycle research? May I reference this for educational purposes? Thank you!

This just randomly showed up in my recommended. I'm not even in the same continent as your university, but just watching this video prompted me to comment (which I rarely do) and watch some other videos, even though most of them have no relation at all to anything even vaguely related to my life. But this video and a few others are weirdly interesting. You provided good, brief advice on covid protocol, better than many professional youtubers, and that was impressive. This is more just my thoughts than a conventional youtube comment, I just got the feeling that utah university seems quite nice, just from a few videos, and I find myself wishing I could attend this semester........ and maybe even have doughnuts with the Dean. :p

Working with my company to fund my degree and already got the ball rolling. Gonna be going here at the U's Department of Physics and Astronomy to get my degree in Astrophysics. Super excited

Cross reference these lectures with Dr. Chris Knobbe's presentation on SEED OILS!!! Then hear Dr. Eric Berg, Jason Fung, and Dr. Boz.

Thanks for sharing. I had the chance to view a rocket launch in 2018. Memorable experience. I uploaded a pretty cool video of the trip to my channel.

Thank you so much for posting this here. Tried to watch my best friend on the school website and it wouldn't load past 24 seconds of video. I really appreciate you making this more available.

This man is great.

Thank you for uploading. I had the chance to see a rocket launch in 2018. Incredible experience. I uploaded a pretty cool video of the journey to my channel.

Great presentation, thank you!!

I love both organic and electrochemistry. This is perfect for my undergraduate thesis!.
