There is no trace of phosphine in Venus's atmosphere.



Sofia-telescope found no evidence of life on Venus. And there is no phosphine in that planet's atmosphere. So that thing means that Venus is dead. 

But the question is why the first telescope saw phosphine in the Venu's clouds and then that phosphine is gone. The wrong calibration might be the problem. But how telescope couldn't detect that the source of phosphine is in Earth's atmosphere? There was not very much phosphine in Venus.

So maybe the reason for that trace was some chemical reaction where some volcano released phosphorous into Venus's atmosphere. And then things like lightning caused a reaction where carbon monoxide reacted with phosphorous. 

There is a possibility that the lightning destroyed CO or CO^2 molecules. And then phosphorous could interact with hydrogen forming PH3. So there are no lifeforms in Venus's clouds.

Antarctica is the perfect place for researching isolated ecosystems. 


There is the possibility that hidden ecosystems are lurking inside Antarctica's ice. 


But a search for extraterrestrial lifeforms continues. And Antarctica offers a good place to research the closed ecosystems. When researchers are collecting data from the lakes deep inside the Antarctic ice. 

Also from the ice itself, they can make models of what kind of lifeforms could live in some distant water moon's ocean. Antarctica is also a large freezer. And there can be found the remnants of the first organisms on Earth. 

The thing is that Antarctica is one of the most isolated and sterile areas in the world. There are unique species in those lakes that are not anywhere else. And those organisms can give information about the closed and cold ecosystems. 

Antarctica is hostile to almost all lifeforms that we know. But deep inside ice is lifeforms that don't need sunlight or straight contact with sunlight. Those organisms hunt for organisms that have contact with sunlight. And in that model, the tiniest and most producing organisms are living near the ice's surface. After that the other organisms. That is higher in the food chain are deeper under the ice.

The big question about those closed ecosystems is this. Does the nutrient fall to those lakes through the ice? Or are those lake ecosystems closed? In the last case, all nutrients surround the icy lake. That kind of ecosystem gets its energy from the black smokers or volcanic heat. That kind of ecosystem is always interesting.

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...
