I'm 73, so I have some perspective on the advances in biology (and the other sciences) in the last few decades. What we know today is mind blowingly different from what we knew when I was young - and what we will know in another 30 or 40 years will make what we know today look extremely primitive. We think we know a lot now - and yes, we do - but it is still just a very small part of all there is to know. Yes, this is fascinating. And there's more to learn about cells and their interactions than we can currently imagine. Whenever you hear someone say "this is how cells work" or "this is how the brain works" - laugh at their hubris, value your own not knowing about these things, and cultivate patience for the results of future research. "We don't know much about that yet" is the most productive attitude you can have about most scientific topics you encounter. People who can't handle not knowing are not suited to any kind of work in teaching or scientific fields.

78 y.o,. here. Not only that, but biochemical experimentation has always been done using purified components such as proteins and RNA in water solutions. Whereas the interior of a living cell is anything but watery and pure. We need to know how proteins and enzymes interact with each other and with small molecules in the crowded gel that is the cell interior. Clusters of functional proteins may be how proteins find each other when simple diffusion is inhibited in the high-viscosity environments of cytoplasm, nucleoplasm, etc. Yes, the subject is extremely important and it looks like it could completely revolutionize the subjects of biochemistry and cell biology.

Hello Anton, I mentioned in a comment to another video that I helped organize a conference at the Strathcona back in 1999, together with Dr. Vali, Eddie Chan and Gitta Jensen. One of the people Gitta and I wanted to speak at the conference was a very old biologist named Bernard Grad, who had written his doctoral thesis on the roof of the Strathcona in around 1950. His thesis is that organized life requires a protected environmnent and that such an environment, a membrane, could form under certain chemical conditions. Dr. Grad was too old to attend the event, but one person who was not quite too old was Lida Mattman of Wayne State university. SHe wrote the book on Cell Wall Deficient Forms, taking a somewhat different approach. The conference was titled Pleomorphic Organisms in Health and Disease.

At 3:12 when you first mention Intrinsically Disordered Proteins, the visual shown features a molecular truncated icosahedron (like a wireframe model of a soccer ball/football). I find these and related geometrical forms very fascinating and fun to model. What is that shape or form or figure referred to as in a biomolecular setting? Or does it represent a number of possible things, perhaps depending on individual chemistry? Does it/do they have a particular function or set of functions? The same shape appears in another visual at 10:45 Also at ~10:15, the revelation that functional solids can be formed without membranes or other protective elements is a bit mind blowing. Very cool!

I think that at some point, the loss of rigid cell walls in eukaryotes allowed them to develop strategies where they could fuse to combine genomes. As for the magic that causes the development of the body, there's an emerging field of bioelectricity that studies some of the behavior that structures organs. A lot of the machinery involved is repurposed from cellular sensory apparatuses, mostly the ones that detect ions and electrical activity, that cells would use to figure out where to go when they were single cellular, (to avoid predators, to find food, etc..) I'd also look at the evolution of sea sponges and tunicates.

Concentration gradients of signal molecules. It's easier to understand if you take a look at the first couple of generations of cells during embryo development. But essentially the idea is.. the embryo divides into a ball of cells, then chemical signals emitted from one pole of embryo form a concentration gradient, and genes are activated/suppressed conditional on the concentration amount. This triggers cell differentiation + the emission of new chemical signals and sets up new concentration gradients, which leads to more gene activation/suppression.. and so on. It's basically a computer algorithm, but running on biological/chemical substrate.

The original central dogma of biology apparently needs to change from DNA -> RNA-> Protein-> Phenotype to DNA RNA-> Control-> Protein-> Phenotype for including control function and to show the two-way interaction between DNA and RNA, according to a biologist. In the light of new findings such as this, it might change yet again to reflect the fast changing landscape of biology.

When you said, structure becomes function it made me think quite hard, because we can see this principle in many other places too. Its very fascinating how RNA can protect itself via forming these clusters - I eventually read the paper although I am not a molecular biology major - but this is astonishing - I wonder what the chemo-physical parameters are that make RNA transform itself.

11:09 I wonder if the model of 'how life started in the beginning' is hiding in plain sight. Perhaps this process is exactly how it got going and happens every moment in our cells. When embryos develop they go through various morphologies, such as those of fish, before becoming human-looking, as if the whole process of evolution has to be replicated in order to 'climb the ladder of complexity' before reaching the latest form. By analogy, I wonder if a similar process takes place inside our cells all the time - as if the RNA has to repeat the processes that started life in order to reach the most recent stage of evolution. 12:02 On the contrary, coming at almost the same time as the advent of AGI (OpenAI o3 model), this portends the dawning of a new age of understanding and incredible scientific advances. I think there will be practical benefits sooner than you may think.

A good theory and increasing size of life. It creates clumps and by chance it functions and to have a certain function it requires a certain size like an electric circuit. For instance, a virus is much smaller than a bacterium and you might think the smaller RNA object came first, but given the efficiency of RNA the bacteria are about the size package you need for their function. And it is possible the function occurs in the clumps then the membrane, feeding, and reproductive function occurs by chance.

I think it may be a new type of catalyzing : maybe they use crystal structure to force or facilitate certain reactions or molecules configurations... like using the forces involved in a state transition of some molecules to manipulate other molecules trapped inside the crystal... in that case, these formations would only be transitory... like 3D molds forming around molecules to get a configuration or reaction and then the mold dissipate to liberate the results. This is so fascinating ! I also think we should give up this idea of "evolution innovation" when we look at how things are done inside the cell, or at least not confuse our understanding of what "can happen" with the tree of life... everything that RNA can do, as molecules, would probably appear randomly very early in life.. in other words, if this type of reaction or organization mechanism is possible, it always was. Life can invent "new molecules" but laws of chemistry don't evolve.

There could be a type of RNA-based cell out there we haven’t discovered yet. But the fact of the matter is DNA is a much more stable compound than rna and it’s thought that in the primordial environment of early earth dna life forms that used rna and proteins for complex reactions outcompeted earlier ‘models’ so to speak. Therefore, it’s reasonable to suspect that rna life forms no longer exist since dna life is so much better at thriving. Viruses , yes, are a bit more complicated. We don’t know how they quite fit into the narrative, but there are theories out there. But as far as _cells_ go you can almost think of things from a Darwinian standpoint. But rna world at the end of the day is just a theory. It might be dead wrong lol

I no longer accept the life-from-primordial-soup theory, but nonetheless this is a wondrous discovery about the formation of eukaryotic (and prokaryotic?) life forms.

I wonder if these can explain a lot of the autoimmune conditions that today we just dump in the Idiopathic bucket.

I wonder if stressful circumstances induce protein signaling within cells which would allow for an environment that would form these condensates more easily. Like I wonder how the cell regulates these condensate organelles .

I also wonder if miRNAs are involved in these condensates .

Wondering if Prions “mad cow disease” are also in the same category of those

In the same category as these organelle condensates? Not quite. Prions are misfolded proteins that build up in cell structures . They’re countless and aren’t broken down via ubiquitin easily either. They end up building up in neurons and causing diseases like cruetzfeld-Jakob

Scary thought is the known universe reflects this. We may be in the process of becoming. Chicken and egg analogy. Microcosm / Macrocosm ?

So that discovery means that cells are more complex than people thought before.
