Peto's paradox: why whales don't get cancer?

 Peto's paradox: why whales don't get cancer?



There is introduced an idea in the Cosmos Magazine. That the rapidly evolving genes cause that whales can't get cancer. But also water is protecting them against UV and other electromagnetic radiation as well as alpha and beta radiation. So maybe lack of natural EM- radiation causes that whales don't get cancer.

Whales are enormous animals. They live a long life. Also, whales carry lots of fat. And the new thing that makes those great animals interesting is that whales have no genetic mutations. 

And they don't have cancer. The genomes of the whales have less mutated than other animals. So what is the thing that makes whales so wealthy if we are thinking about cancer? 

One of the things that can save whales from cancer is that water protects them the natural radiation. Water absorbs radioactive radiation better than air. And good senses may be protected whales also against poisons like carcinogens. There is a possibility that the poisons like PCB and some carcinogens are making fish so bad smelling that whales can avoid them. 

And water is protecting them against UV radiation. But the genomes that are protecting whales against cancer are also mapped. If we are thinking about the cure for cancer theoretically is possible to create vaccines. Those are protecting us against the changes of the cells. But without knowledge of the forming of cancer is impossible to search for the changes in the protein layer. 

Those membrane proteins of the cells are the thing that the immune system uses for finding those cells. But making that kind of vision is a very challenging thing. The thing is that when the cell is turning into a cancer cell. There must be some changes also in its surface proteins. The reason is that. When the DNA of the cell is damaged. It cannot control the production of the surface molecules of the cells. 

That damage in genomes has an effect on other things than just the ability to die or split. The DNA controls every single action in the cells. The core proteins of the cells are extremely complicated. And if there are damages in the DNA. That causes changes also in the structures of the proteins of the cells. Those anomalies can use to track and destroy cancer cells by benefiting own immune cells of the people.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
