Can we find lifeforms in the icy moon's oceans, or in Venus's clouds?


"An artist’s rendition of Saturn’s moon Enceladus depicts hydrothermal activity on the seafloor and cracks in the moon’s icy crust that allow material from the watery interior to be ejected into space. New research shows that instruments destined for the next missions could find traces of a single cell in a single ice grain contained in a plume.

The next step in the search for extraterrestrial lifeforms is to search them in the ice grains of the icy moons. The icy geysers can send ice grains into the gas giant's orbiter. And those ice grains can involve the alien bacteria's DNA. It's possible. Those icy moons are not habitable. 

But when we think about the possibility of finding some kind of lifeforms on those moons, Or, the lifeforms can rather be found in those moons' icy oceans. The DNA-based lifeforms might not be similar to bacteria on Earth. 


"The drawing on the left depicts Enceladus and its ice-covered ocean, with cracks near the south pole that are believed to penetrate through the icy crust. The middle panel shows where authors believe life could thrive: at the top of the water, in a proposed thin layer (shown yellow) like on Earth’s oceans. The right panel shows that as gas bubbles rise and pop, bacterial cells could get lofted into space with droplets that then become the ice grains that were detected by Cassini.

Things like RNA and DNA-type self-replicating molecules can act like lifeforms. Or they can just make copies of themselves. Those molecular von Neumann machines can create copies of themselves. But they might not make anything else. If there are self-replicating molecules, That means those things don't leave a mark on the metabolism.  

The plasma spectrometers are tools. That can find the DNA or RNA in the areas around those moons. And if there are some lifeforms, They are very primitive. That means those primitive organisms can be far from things that we know from Earth.

Can there hover some kind of lifeforms in Venus' clouds? 


When somebody makes a model of Venus and its conditions, they sometimes forget that Venus' atmosphere is mainly carbon dioxide or carbon monoxide. Conditions on that planet are different from those on Earth, and hovering in the carbon dioxide atmosphere is much easier than in Earth's atmosphere. 

The oxygen balloon will rise in that atmosphere as a helium balloon rises on Earth. Hypothetical lifeforms can hover in Venus' atmosphere by separating carbon from carbon dioxide. The surface is too hot for lifeforms, but the clouds can be suitable for some archaebacteria. 

Life on Venus is impossible, if we mean lifeforms on that planet's surface. But in the mountainous areas. And in Venus' clouds can hover over some lifeforms. Those lifeforms can be procaryotes that can hover in those clouds. Astronomer Carl Sagan introduced medusa-looking lifeforms that could hover in gas giants like Jupiter's atmosphere. 

But in some models, hypothetical hovering lifeforms are smaller than human cells. Those hovering lifeforms can use oxygen gas tanks to hover in Venus' carbon dioxide atmosphere. The creature must just separate carbon from carbon dioxide. And then it can hover in Venus' clouds using the oxygen.

Researchers created fully functioning mini brains using bioprinters.

  "Currently, the global annual cost of treating brain diseases amounts to €3 trillion. (Image: Mostphotos)" (University of Helsinki, Development of human-derived mini-brain close to completion - A new technical solution promotes the treatment of brain diseases) When we think that AI cannot reach the same intelligence level as humans, we talk about binary-computer system-based AI. That AI is a very passive thing. But biological microchips where living neurons communicate with microprocessors are different things. Those systems are in mini-brains. Or cloned neurons that developed for medical testing. Those mini brains involve living neurons that interact similarly, to neurons in the human body.  "Scientists at the University of Wisconsin–Madison (UWM) say they have created the first 3D-printed brain organoids that function like natural brain tissue." (FreeThink, Scientists create the first “functional” 3D-printed mini brains) “The neurons communicate, send signals, i

Researchers found a "pause" button that can stop the human embryo advance.

Researchers found a "pause" button that can stop the human embryo advance. And that thing can have many solutions. In the case of a mother's illness or injury, the medical team can save the embryo's life by stopping its advance. But that ability can make things like interstellar travel possible.  It's one theoretically, a very easy, way to transfer people to the other solar system if we don't want to get them back. The mission controllers can use the human embryos for the other solar system. Those colonists can have the robot controllers, and they can have the training material for the mission. That thing might not yet be possible. Because of our culture and moralistic-ethical thinking. Of course, technology sets limits to that kind of project.  "Research indicates that humans might harness a dormant diapause-like capability to optimize reproductive health and IVF success.

The Pentagon published its new UFO report and found no evidence of the alien connection.

Image
SR-71 The Pentagon says that they have no evidence of the UFO's extraterrestrial origins. But even if there is no evidence that aliens are behind the UFOs, we must keep our minds open. The alien message to radio telescopes is not a spacecraft from another solar system. And spacecraft from another solar system can be probed. Nobody confesses to holding alien spacecraft, but the world is full of extremely rare aviation vehicles. And that means UFOs are true, but aliens are not. Says Pentagon. So if most of those UFOs are the Pentagon's secretive military projects. There are still many interesting things.  That means the famous Roswell Alien, which has the main role in the footage Alien Autopsy can be the human-looking robot. That explains rubber and other things in that character. So the film is real, but the object of the autopsy is a robot, not an alien. You can search this film from the net using keywords: "alien autopsy".  Maybe most of the UFOs are Pentagon's h
