Machine learning meets chemistry.

Machine learning means. The system makes memos about things that it does. A learning machine is like a man, who writes in a notebook. And then that machine can escalate those notes over the entire system. The learning machine is like some laboratory assistant, who writes everything that is done in a test environment with chemical tests into notebooks. In machine learning, computers make those memos automatically.

In chemistry, that means that the system observes some reactions, and then it puts all the details in the memory. This thing helps the AI-based systems to multiply the chemical and physical environment for the chemical reactions in other laboratories. The AI-based system can transform the test environment conditions straight into full-scale systems and reactions. That thing makes chemical research and development faster than ever before.

Along with things like nano printers and attosecond lasers that thing can make the new type of chemical compounds. The nano printers allow creation the of catalytic layers with accurately adjusted surface area. The attosecond lasers can observe chemical reactions with ultimate accuracy. The attosecond lasers can adjust the energy levels in molecules and even turn the molecular bonds out from the environment. That allows to connect the ions and atoms into the molecule's certain point.

In those systems gravity is a problem. In complex 3D structures, all kinds of disturbances and artifacts are problematic. If the gas mixture or some other things in the reaction chamber is wrong, that is catastrophic. That thing makes automatized orbital laboratories important. Those laboratories are small-sized satellites there remote control system makes molecular structures in the zero-gravity environment. And that thing makes the revolution in chemistry.

The same methodology. That used in complex chemical structures can also used in complex material structures.

The ability to make complex 3D structures makes it possible to create new types of composite materials. The researchers can make a material with an extremely large surface area to clean toxic chemicals and carbon from the air. The box-like structure below the graphene surface can turn material very hard, and resistant to impacts.

The 3D structures that can make the soundwave jump across it can used to make rooms and materials without echoes. That kind of material allows researchers to create a pure acoustic test environment. The graphene layer that is connected with a box structure using nanotubes can used for the new acoustic materials. The nanotubes transport wave movement to a nano-acoustic layer that conducts energy from soundwaves into itself.

In some models, nano springs connect those nano-boxes. Nano springs are the DNA bites. The idea is taken from nuclear-protecting bunkers. They are like boxes that hover in the artificial caves. When energy impulse hits those points the bunker that is hanging on hydraulic pistons in the water layer would survive.

There are tubes around the water layer. They allow the water to expand in those tubes if the pressure or seismic strike hits the ground. The water layer covers the bunker against the seismic impulse. The hydraulic pistons also minimize energy transport to the box. In nanostructures, that thing makes it possible for the material can maximize energy absorption from the pressure impulses. And that minimizes echo from the structure.

Black holes cause a virtual redshift because gravitation stretches the wavelength near them.

At the beginning of this text is a film about the redshift of black holes. Gravitation stretches light, and that means gravitation fields are pulling waves longer. That thing is called the gravitational redshift. As you can see from the film, the black hole stretches radiation and distorts the redshift. Gravitational redshift, or virtual redshift, means that a black hole might seem to be at a longer distance than it is. The film shows the redshift of the star that orbits a supermassive black hole. But all other black holes interact the same way. The event horizon is always constant. At that point, the black hole's escaping velocity is the same as the speed of light. So every black hole interacts basically in the same way. And it's possible to apply that model to all black holes irrespective of their size. Is gravitation the thing that forms dark energy? That thing seems somehow strange. But when photons and other particles are traveling through the ball that forms the visible

The shape of the brain means more than neuro connectivity.

Well, we might say that the brain is in its entirety. Another thing is that all things in the brain have some kind of purpose. The shape of the brain and, especially, the folding of the brain shell are extremely important things. Those folds are expanding the brain's surface areas. And the brain shell has a primary role in the thinking process. The surface area of the brain determines how large the cerebral cortex is. And in a large cerebral cortex, there are a large number of neurons. But as I just wrote, the brain is in its entirety. "Researchers have discovered that the shape of a person’s brain significantly impacts thought, feeling, and behavior, overturning the prevailing emphasis on complex neuronal connectivity. Utilizing MRI scans and the principle of eigenmodes, they found that brain function is closely linked to its geometric properties, much like how the shape of a musical instrument determines its sound, offering new avenues for exploring brain function and diseas

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel.

New nanomaterial is 4 times harder than steel. And, at the same time 5 times lighter than steel. The new material is the hollow glass fiber with DNA molecules inside that structure. Or as you see from the image. The glass fibers are on both sides of the DNA. DNA molecule is the thing, that involves the genetic code of the cells. Genetically engineered cells can make DNA, and those molecules can used as the nanomaterial's structures. DNA manipulation makes it possible to create new types of extremely strong materials. And those materials are stronger than steel and lighter than it. DNA molecules can act as nano-size springs. And in some visions, genetically engineered cyborg cells like cyborg macrophages can make extremely long DNA molecules. And then they can just use those molecules as spears that can pierce wanted cells. Or those cyborg cells can also dumb targeted cells full of the DNA that terminates them immediately. The DNA and nanotube combinations can also act as DNA-b
