Biotechnology is an ultimate tool for medicine.

When we are thinking about the case. Where the human blood cannot transport oxygen we can use genetically engineered bacteria to replace missing blood cells. Those bacteria can form oxygen inside them and then help the person whose blood cells are destroyed or unable to work as they should.

The principle of those bacteria is similar to bacteria that turn carbon dioxide to fuel. But in that case, the bacteria can turn nutrients into useful things in the human body. Those genetically engineered bacteria can use in cases, where a person is injured in an accident.

Or they can be used in other cases when the blood cannot transport enough oxygen. In cases like leukemia, the medical staff must destroy the entire bone marrow to remove cancer cells. So during that process, those genetically engineered bacteria can deliver oxygen to the person's body.

There is also possible to change the DNA of the bacteria to the DNA. If that DNA is taken from the wealthy bone marrow cells. That allows the cloning of those cells by using the patient's cells. This thing means that there is no rejection.

When we are developing technology, we should ask where this technology can also use.

I have written the toothbrush nanomachines somewhere before. The nanomachines that can dish your teeth are marvelous systems. They can remove bacteria that are causing carries. But the same systems can also use for removing plaque from the blood vessels. And maybe someday in the future, those nanomachines can make it possible to remove plaque from the nervous system.

And that thing could revolutionize the treatment of Altzheimers and cancer. The nanomachines that can remove organic and inorganic material from the layers are suitable almost for every purpose where is needed the cleaning. Those things can use for cleaning tubes under the cities. And this thing makes those systems interesting.

Similar systems that are created for removing bacteria from teeth can be used for many other purposes. The nanomachines are awesome tools. They can remove things like non-wanted cells and bacteria from the places where regular workers, antibiotics, and surgeons cannot operate.

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
