Interesting videos about science

Not an video, just a drawing:

In 2022, Wageningen University, in the Netherlands, digitized and put online 1,180 drawings from 40 years of research on the root system of plants and therefore that of trees, these large plants whose woody stem branches from a certain height above the ground

Magnetic fields "bending" light paths
Hmm... 🤔
Q: (A) Can space with fractal properties, non-differentiable structure, non-smooth structure, be used to derive Schroedinger equation and quantum theory like the Nottale is proposing in some of his papers?
A: Close.

Q: (A) What is incorrect? Why is it only close?
A: Light bends at intervals. Look to the quasar for the clue.
 
Some people here already know the name of this scientist - Anton Petrov -, but YouTube found this video for me about the latest brain research. Very interesting!
The timestamps:
0:00 Recent papers on the human brain 1:00 Human brain atlas and 3000 new types of cells 2:00 What was this collaboration for? 2:40 Unexpected complexity of cells in certain brain parts 4:00 Are there a lot of individual differences? Yes! 4:40 Physical structure appears same across species 5:10 Genetic activity is very different though 5:35 Human disorders are unique to humans 6:30 Unusual layers protecting the brain - SLYM 7:38 Axons turned out to be more unusual, especially in other species 9:35 Shape of the brain suggests apes and humans are similar only until adolescence 12:15 Hippocampus in humans is unique focusing on vision...explaining art? 13:48 New memory cell discovered15:45 Limitations
 
I'm not sure why, but NASA says:
It's Black Hole Week! Grab your telescopes and get ready for a week of black hole exploration.
Black Hole Week - NASA Science

Hang out at the event horizon with us this week​

Come and learn about these strange balls of gravity here and on social media. Check out the links below to find our latest content and follow the #BlackHoleWeek hashtag on social media for even more content. No matter where you go this week, we hope that you’ll find yourself teetering on the edge of the event horizon — just don’t fall in!
  • Monday, May 6​

    Welcome to the event horizon! Let’s get close to one and see what it would look like.
  • Tuesday, May 7​

    All black holes have an event horizon, and the object’s mass defines the size of the horizon. Learn about black holes of all sizes, big and small.
  • Wednesday, May 8​

    Even though light can’t escape once it’s inside the event horizon, we can still detect black holes by monitoring their effects on their surroundings. Follow along to find out more.

NASA Simulation’s Plunge Into a Black Hole: Explained​

This new, immersive visualization produced on a NASA supercomputer represents a scenario where a camera — a stand-in for a daring astronaut — enters the event horizon, sealing its fate.
Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation.
The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way galaxy. To simplify the complex calculations, the black hole is not rotating.
A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole and serves as a visual reference during the fall. So do glowing structures called photon rings, which form closer to the black hole from light that has orbited it one or more times. A backdrop of the starry sky as seen from Earth completes the scene.
The project generated about 10 terabytes of data — equivalent to roughly half of the estimated text content in the Library of Congress — and took about 5 days running on just 0.3% of Discover’s 129,000 processors. The same feat would take more than a decade on a typical laptop.



This video reminded me of a transcript in which Ark was working on a theory:
Q: (A) He has this obsession with using variable units... iso-units... and he has this view of gravity that is similar to the view of some other Russian physicists... and, according to him, space-time is flat. It is just a flat space with an iso-unit - a deformed unit. This is contrary to Einstein where space-time is curved, and you have worm-holes and all kinds of topological features. But, for Santilli, space-time is a flat space with time. Is he right in this?

A: And flat cannot curve?

Q: (A) If something is flat, it cannot have a hole, or a wormhole... if it is flat, it is flat. It cannot get a hole which is connected to the other hole.

A: What if the "hole" is parallel to the plane of the flat curve, rather than perpendicular?
 
Ever heard of Imputation, Contextualization, Ecological inference, or Synthetic control?

Well, those fancy terms describe how you can make up data to publish in articles or scientific papers.

Now, who would have thought that this would be a thing in science...? This video does a good job of explaining how this works, and how it is exploited.

 
Imo this is huge:

Also from his website:
The notion that "body pattern is stored in the DNA" is not that simple, depending on what you're asking. What is stored in the DNA is protein sequences, which is single cell-level hardware information. Bioelectric patterns emerge from the complex dynamical interactions of ion channels and gap junctions opening and closing, and it's that physiological software that stores and processes patterning information.

That's very interesting! Here's an excerpt of the video transcript covering the most important part, for people who don't have time to watch the video:

Q: "if I understand you right, what you're saying is that most of biology today has sort of taken place trying to do the equivalent of machine code programming, of understanding the biochemical signals between individual cells, there's this electrical language, which, if you could understand that, that would give us a completely different set of insights into how organisms are developing.
DNA is not controlling the actual final shape of these organisms."

A: "We turned on and off the little transistors -- they're actual ion channel proteins -- that every cell natively uses to set up this electrical state. So now we have ways to turn them on and off, and when you do this, one of the things you can do is, you can shift that circuit to a state that says "build two heads/ build no heads".
We generated two head worms and we did a crazy experiment. You take one of these two-headed worms and chop off both heads; you leave just the normal middle fragment. You ask what is it going to do in plain water, and the standard paradigm would say, the genome is not edited so it should make a perfectly normal worm.
These worms, when cut again and again, in the future, in plain water, they continue to regenerate as two-headed.
The pattern memory to which these animals will regenerate after damage has been permanently rewritten. And in fact, we can now write it back and send them back to being one-headed without any genomic editing.
So this right here is telling you that the information structure that tells these worms how many heads they're supposed to have is not directly in the genome. It is in this additional bioelectric layer."
 
@meadow_wind Thank you for that.
And yeah its amazing, it shows that reprogramming the biological code can be done by some sort of electromagnetic waves. Like information (software) is in steer behind the matter (hardware). [If I understand it right].
 
@PabloAngello You are welcome! I thought it was of interest to the forum members since many transcript speaks of proteins being antennas. Thus, this research seems important and might have been skipped by other members without any description of the video content.
