NASA:s new mission to return samples from Mars astonish the world.

The new mission where probes are bringing samples from planet Mars to Earth can be even more interesting than the JWST telescope. For the first time in history. The mineral samples will be taken from another planet. And take it to a special laboratory.

And one of the reasons why NASA wants to make that mission is fossils that are found from meteorites. Those samples can answer was there some kind of bacteria living on Mars. There was water on Mars before it lost its lithosphere and there could live some kind of primitive procaryotes on Mars. If that thing is true the next question is where life was formed.

The fact is that water is more common in the universe than nobody expected. And even if there is no free oxygen in the atmosphere of some planets the hypothetical lifeforms can create oxygen straight from water by cutting water molecules by using electricity. Those cells can form electricity by using similar cells that electric eels use to create electric shocks. And the electric cells can get their power from photosynthesis. The fact is this.

The first bacteria on Earth were not vegetables or animals. They were photosynthetic creatures that could move. Free oxygen was poison for those bacteria same way it poison also to some anaerobic bacteria. So maybe that kind of creature formed also on other planets. And then impact with asteroid ended the story of the life on Mars.

Maybe those samples that NASA brings to Earth can confirm that theorem. But there is the possibility that those fossils are not covering the entire red planet. They might exist only in places where was no ultraviolet radiation. And there is a possibility that samples are taken from sterile areas.

And there is, of course, the possibility that those bacteria will not be found on those samples. That can tell that there was no life on Mars. But it's always possible that the rover that takes those samples accidentally collects stones where are no fossils by selecting them from next to stones where are fossils.

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
