Empowering voices - Advancing social mobility in the chemical sciences
Просмотров 183Месяц назад
It is a widely held belief that university plays a key role in increasing social mobility. However, the stark reality is that students from high socioeconomic backgrounds are three times more likely than those from low socioeconomic backgrounds to attend university. As a result, the former tend to gravitate towards top selective institutions, while students from low socioeconomic backgrounds fa...
Driving the battery recycling revolution

Improving battery performance with cutting edge 3D chemistry modelling simulation webinar
If every living thing we know is made from / by these molecular machines, do these machines ‘evolve’ as well or have they remained the same since the first cell millions of years ago ? Did dinosaur cells have the same molecular machines ? Or did dinosaur molecular machines look different and evolve to the become the ones that exist today ? It seems that the machines or ‘code language’ Is the same , but the commands / coding produces different living things ?

This is incredible
🤣
I keep replaying this for the song

Are some parasitic reactions endothermic? 1:04:26
So good to hear. Sun is the ultimate energy source & so rain. People do want EV, Electric motors, but what will corrupt leaders do ? Now Science is so explored that each educated / genius can play important role despite blockage from America and China. China is eating all while America is destroying all.
I find it amazing that it all this highly-refined, seemingly purpose-built, nano-level structure all just happened by random accident.
Do you believe that or are you being sarcastic ?
Have you seen what computers are able to achieve by brute force and random chance?
But humans will say the human body has no intelligent designer. I don't care if you call it god or aliens the Human Body is a perfect biological machine.
What's remarkable to me is people cannot deny intelligent design in this, but reject the designer.
If you cannot accept miracles that are not designed, you must accept the miracle of the existence of a designer. Doesn't the existence of the designer of such miracles need to explain its origin? Isn't its existence ingenious? Isn't it the result of wisdom? Then there must be a designer above the designer. Unless wisdom comes out of thin air. This assumption is even more bizarre than the ingenuity of life coming from billions of years of evolution.
@@yikebendan Blah, blah, blah... and in summation, There Is No God. In other news, we'll be praying for you.
"Unless you people see signs and wonders, you will never believe" -Christ It's just the way we are, don't blame them.
@@yikebendan The creator isn't subject to the rules of his creation. God exists before time, before matter, in the same way a person might start a computer program, your existience isn't reliant on the program running and your program runs with the rules you've designed. When the program closes, you still are just as you were before it began. It's far simpler than the idea of complexity arranging itself from chaos, which we never observe.
Prove it@@kriegjaeger
Is the exact DNA/RNA sequence for producing this mechanism known already? If not, it should be a priority to discover it because it opens the doors to biological nano-machines.
It already is. I suggest looking at databases such as the Protein Data Bank.
This stuff blows my mind. Molecular machines are so amazing.
What's up with the off-brand circus music?
Because it's like a merry go round. Get it? (Yeah, it's stupid.)
You can see diagrams of this in the voynich manuscript at Yale . It's a medical school I heard . Shame they're clearly incompetent.
Saw all this shit while on an eighth of penis envy shrooms... thank God I didn't hear carousel music. God is Great
I am interested in understanding how they have negotiated with the rear earth metal holding countries for continuous supply for the sake of creating permanent magnets to ensure efficient locomotion, it is also important for us to know how they could have stayed profitable for so many years, and I presume they might have made a killing in earning carbon credits
Somebody is on that mota
imagine solving this unbelievably cool structure and the press puts this music over it
I was looking for this comment
carousel, I think this is the link between the two things
I think it's supposed to go with the merry-go-round resemblance of the mechanism.
Ah yes... *woosh*. It's even oriented to look like a carousel. I thought it was just randomly chosen stock music. @@It.s-just-me
The press lol
شكرا جزيلا لكم ❤
Where are the axles for these wheels?
there are none - it's an inner wheel, more like a ball bearing assembly than a wheel on an axel. The "axel" is pointing outwards and it's the flagellum that is being spun by this nano-motor.
It basically just "floats" in the membrane. The flagellum whip itself is the axle.
@@Gelatinocyte2 anchored in the membrane. It wouldn't surprise me if there were other trans-membrane proteins involved.
How in the fck does this get assembled ?
yep, it has to be assembled by even more interesting machinery than the nano-motor itself. The DNA/RNA sequence is the key. Mind that it's being produced en masse because it's part of many species of bacteria. By the numbers it has to be THE MOST common engine on the whole planet.
@vaakdemandante8772 what chemical is being monitored by the protein for timing ? Like it has to have a clock ?
Interesting visual. The music overlay was obnoxious and too loud. I did learn something, but this was unwatchable with the sound on.
AHHHHHAHAHAHAHAHAHHAHAHAAAAHH
Oh my god it’s literally just a fucking microscopic gear
Some scientist will be working on a transmission in no time. "Today on Tiny Gear!"
Ya, at the sub-cellular level, it's all nanotechnology, dude, seriously. It's crazy. Biochemistry is wild.
there is also the intercellular signaling via motor proteins literally walking on two legs along a microtubule, shits crazy
this is how i get around btw
I love how RNA leads to the creation of 3D structures which can then do useful things and further combine into more useful things. It’s like a 3D Turing machine but where the output has physical functionality so is infinitely more useful. It’s like the ultimate programming language and computer combined into a single complex process. It’s stunning.
What controls the structures being put in the right place ans formed at the correct time. I know it's physics, but is there a protein for that ?
RNA themselves can also form into 3D structures, examples: ribosomes, tRNA and spliceosomes.
@@RoboArc there are many different proteins for that. The ones I can think of are Chaperonins and the Signal Recognition Particle (which is a protein-RNA macromolecule).
We didn't invented anything, we just remembered how we are made
Today the algorithm blessed me with this knowledge.
Does this mean there are more wheels than doors?
Let me introduce you to: bacteria porins
Unfortunately, you must also take into consideration the many "ports" that permit the diffusion of certain molecules through the cell membrane.
Gotta give credit to all those engineers trillions of years ago, in a galaxy far, far away...
But then what engineered the engineers?
@@crisleightning6158 I'm what you call an atheist, and I know we're all immortal spiritual beings, we're older than the physical universe, so we came first. ruclips.net/video/dEK89-nPyU4/видео.html
Midichlorians are the powerhouse of the force
Boy, if only we had proof or an explanation as to how life began... 😒 🤔 oh wait, we do 😮
Huh?
I *knew* I heard something squeaking while trying to get to sleep.
Interesting, the way that mechanical switch protein changes the direction of the output while keeping the direction of the input the same reminds me of how a car transmission can switch from a forward gear to a reverse gear.
This is obviously a created mechanism that never could happen by evolutionary happenstance. Evolution is saying given billions or millions of years if a tornado continually was rotating over a junkyard eventually you would have a fully functioning car. If Bill Gates used millions of chimpanzees banging away on keyboards for millions of PS of years then eventually you would get Microsoft Windows. Things in nature break down (law of entropy), they don’t come together in intelligent design. Darwin knew nothing of the complexities of living cells or DNA. You have to be “educated” to not believe in God and then you become a fool, since the creation screams the truth of a creator.
The difference between a tornado rotating for billions of years/monkey typing and evolution is that, a tornado starts every next step from complete randomness, that is, all steps are erased after every step. Life is different, once a self replicating chemical reaction occurs, next chemical reaction uses the by products of the first reaction, over time, you have building blocks of life and you don't start over every step like with the tornado. Its okay to believe in god, but it's certainly not okay to present false examples to support your claims. Let me ask you something, the scientific advancements have given us things that religions promised us, aka, miracles of light in darkness (bulb), instantly sending your voice to thousands of kilometres away (voice calls), a magic mirror (a video call), going to the moon (Apollo), just to name a few. But on the other hand, the pope and religious preachers are still preaching that the world will end in next 10 years for the past thousands of years. What makes you still believe in god instead of scientific advancements?
It's great to see glass melting in atomic level. Please let me know is it is a simulation or actual one.
This rotation looks exactly like the ATP manufacturing system (from ADP and another phosphate). I just recently saw this vid (lUrEewYLIQg) by Clockwork, showing a rotating mechanism essentially assembling ATP and the rotation being caused by H+ ion concentration and repulsion. Fascinating. Would love to see a longer version of this flagellum motor vid. Maybe Chemistry World might want to colab with someone, perhaps Clockwork, perhaps even Kurtgestat?
I saw the paper a week or so ago, so when youtube showed me that video you mentioned (today!), I was like "3 years ago??, didn't that just come out?" and now here I am on this video
Important difference is the static portion that makes up a lot of ATP synthase and ensures correct direction of rotation. Only a chunk of ATP synthase actually moves
Did you just say Kurtzgezagt?
I'm more of a WEHI/Drew Berry kind of guy.
Not sure about the exact structure, but the Mot A/B looks indeed a lot like the H plus Motor that powers ATP synthesis. And works of the same principle. If there is indeed structural similaritys or if the genes coding both are related it would give a path for the part that powers the molecular gear.
Hmm but what is turning motA/B? Very interesting. I believe nature knows mechanics better than us so if we study nature we can innovate our technology too.
The ATP reaction within the mitochondria.
@@misteral9045The powerhouse of the cell?
Hmm... Now do it 😂
@@misteral9045wdym, respiration?
I think the motA/motB complex is powered by a proton gradient similar to what powers the ATP synthase.
strange
but very interesting, id like to know more about how this works and how we found this out
Blessed is Allah, the best of creators!
are you normal? It's emergent evolution, not made up god who allows killing and promotes terrorism and self glorification after suicide... Religion is for people who constantly need to live in fear of unknown, and don't want to learn about world...
I'm not sure you realise, but your phrasing means that you acknowledge that there are other creators, which I think counts as blasphemy in most forms of monotheism
Yes but Allah is still the best of them.
