Did Life Exist on Mars and Other Planets? We May Know Soon

Glowing Mysterious Planet

Scientists have developed a groundbreaking AI-based method to detect signs of life on other planets. This method, with 90% accuracy, distinguishes between biological and abiotic samples by analyzing molecular patterns. It promises to revolutionize space exploration and our understanding of life’s origins, with potential applications in various fields including biology and archaeology.

“The Holy Grail of astrobiology” – New machine learning technique can determine whether a sample is of biological or non-biological origin with 90% accuracy.

Scientists have discovered a simple and reliable test for signs of past or present life on other planets – “the holy grail of astrobiology.”

In a paper recently published in the journal Proceedings of the National Academy of Sciences, a seven-member team, funded by the John Templeton Foundation and led by Jim Cleaves and Robert Hazen of the Carnegie Institution for Science, reports that, with 90% accuracy, their artificial intelligence-based method distinguished modern and ancient biological samples from those of abiotic origin.

Revolutionizing Space Exploration and Earth Sciences

“This routine analytical method has the potential to revolutionize the search for extraterrestrial life and deepen our understanding of both the origin and chemistry of the earliest life on Earth,” says Dr. Hazen.  “It opens the way to using smart sensors on robotic spacecraft, landers and rovers to search for signs of life before the samples return to Earth.”

Most immediately, the new test could reveal the history of mysterious, ancient rocks on Earth, and possibly that of samples already collected by the Mars Curiosity rover’s Sample Analysis at Mars (SAM) instrument. The latter tests could be conducted using an onboard analytical instrument nicknamed “SAM” (for Sample Analysis at Mars).

“We’ll need to tweak our method to match SAM’s protocols, but it’s possible that we already have data in hand to determine if there are molecules on Mars from an organic Martian biosphere.”

Key Takeaways from the New Research

“The search for extraterrestrial life remains one of the most tantalizing endeavors in modern science,” says lead author Jim Cleaves of the Earth and Planets Laboratory, Carnegie Institution for Science, Washington, DC.  

“The implications of this new research are many, but there are three big takeaways: First, at some deep level, biochemistry differs from abiotic organic chemistry; second, we can look at Mars and ancient Earth samples to tell if they were once alive; and third, it is likely this new method could distinguish alternative biospheres from those of Earth, with significant implications for future astrobiology missions.”

The Role of AI in Differentiating Biotic and Abiotic Samples

The innovative analytical method does not rely simply on identifying a specific molecule or group of compounds in a sample.

Instead, the researchers demonstrated that AI can differentiate biotic from abiotic samples by detecting subtle differences within a sample’s molecular patterns as revealed by pyrolysis gas chromatography analysis (which separates and identifies a sample’s component parts), followed by mass spectrometry (which determines the molecular weights of those components).

Vast multidimensional data from the molecular analyses of 134 known abiotic or biotic carbon-rich samples were used to train AI to predict a new sample’s origin. With approximately 90% accuracy, AI successfully identified samples that had originated from:

  • Living things, such as modern shells, teeth, bones, insects, leaves, rice, human hair, and cells preserved in fine-grained rock
  • Remnants of ancient life altered by geological processing (e.g. coal, oil, amber, and carbon-rich fossils), or
  • Samples with abiotic origins, such as pure laboratory chemicals (e.g., amino acids) and carbon-rich meteorites.

The authors add that until now the origins of many ancient carbon-bearing samples have been difficult to determine because collections of organic molecules, whether biotic or abiotic, tend to degrade over time. 

Surprisingly, in spite of significant decay and alteration, the new analytical method detected signs of biology preserved in some instances over hundreds of millions of years. 

Deciphering the Chemistry of Life and the Potential for Future Discoveries

Says Dr. Hazen: “We began with the idea that the chemistry of life differs fundamentally from that of the inanimate world; that there are ‘chemical rules of life’ that influence the diversity and distribution of biomolecules. If we could deduce those rules, we can use them to guide our efforts to model life’s origins or to detect subtle signs of life on other worlds.”

“These results mean that we may be able to find a lifeform from another planet, another biosphere, even if it is very different from the life we know on Earth.  And, if we do find signs of life elsewhere, we can tell if life on Earth and other planets derived from a common or different origin.”

“Put another way, the method should be able to detect alien biochemistries, as well as Earth life. That is a big deal because it’s relatively easy to spot the molecular biomarkers of Earth life, but we cannot assume that alien life will use DNA, amino acids, etc. Our method looks for patterns in molecular distributions that arise from life’s demand for “functional” molecules.

“What really astonished us was that we trained our machine-learning model to predict only two sample types – biotic or abiotic – but the method discovered three distinct populations: abiotic, living biotic, and fossil biotic.  In other words, it could tell more recent biological samples from fossil samples – a newly plucked leaf or vegetable, say, versus something that died long ago. This surprising finding gives us optimism that other attributes such as photosynthetic life or eukaryotes (cells with a nucleus) might also be distinguished.”

AI’s Analytical Capabilities in Unraveling Complex Patterns

To explain the role of AI, co-author Anirudh Prabhu of the Carnegie Institution for Science uses the idea of separating coins using different attributes – monetary value, metal, year, weight, or radius, for example – then going further to find combinations of attributes that create more nuanced separations and groupings. “And when hundreds of such attributes are involved, AI algorithms are invaluable to collate the information and create highly nuanced insights.”

Adds Dr. Cleaves: “From a chemical standpoint, the differences between biotic and abiotic samples relate to things like water solubility, molecular weights, volatility, and so on.”

“The simple way I would think about this is that a cell has a membrane and an interior, called the cytosol; the membrane is pretty water-insoluble, while the cell’s content is pretty water-soluble. That arrangement keeps the membrane assembled as it tries to minimize its components’ contacts with water and also keeps the ‘inside components’ from leaking across the membrane.”

“The inside components can also stay dissolved in water despite being extremely large molecules like chromosomes and proteins,” he says. 

“So, if one breaks a living cell or tissue into its components, one gets a mix of very water-soluble molecules and very water-insoluble molecules spread across a spectrum. Things like petroleum and coal have lost most of the water-soluble material over their long histories.”

“Abiological samples can have unique distributions across this spectrum relative to each other, but they are also distinct from the biological distributions.”

3.5 Billion Year Old Black Sediments

The technique may soon resolve a number of scientific mysteries on Earth, including the origin of 3.5 billion-year-old black sediments from Western Australia — hotly debated rocks that some researchers contend hold Earth’s oldest fossil microbes, while others claim they are devoid of life signs.

Other samples from ancient rocks in Northern Canada, South Africa, and China evoke similar debates. 

“We’re applying our methods right now to address these long-standing questions about the biogenicity of the organic material in these rocks,” Hazen says.

And new ideas have poured forth about the potential contributions of this new approach in other fields such as biology, paleontology, and archaeology. 

“If AI can easily distinguish biotic from abiotic, as well as modern from ancient life, then what other insights might we gain? For example, could we tease out whether an ancient fossil cell had a nucleus, or was photosynthetic?” says Dr. Hazen.

“Could it analyze charred remains and discriminate different kinds of wood from an archeological site? It’s as if we are just dipping our toes in the water of a vast ocean of possibilities.”

  1. Only a fool would believe that there’s nothing there at all

  2. RE: “artificial intelligence-based method distinguished modern and ancient biological samples from those of abiotic origin”

    It’s establishment propaganda to promote AI… ‘see how great AI is for all of us!’

    Like with every criminal inhumane self-concerned agenda of theirs the psychopaths-in-control sell and propagandize AI to the timelessly foolish (=”awake”) public with total lies such as AI being the benign means to connect, unit, transform, benefit, and save humanity.

    The official narrative is… “trust official science” and “trust the authorities” but as with these and all other “official narratives” they want you to trust and believe …

    “We’ll know our Disinformation Program is complete when everything the American public believes is false.” —William Casey, a former CIA director=a leading psychopathic criminal of the genocidal US regime

    The proof is in the pudding… ask yourself, “how is the hacking of the planet going so far? Has it increased or crushed personal freedom?”

    The TRUE narrative (ie empirical reality) virtually no one talks about or spreads is that the TRULY big threat with AI is that AI allows the governing psychopaths-in-power to materialize their ultimate wet dream to control and enslave everyone and everything on the whole planet, a process that’s long been ongoing in front of everyone’s “awake” (=sleeping, dumb) nose:
    https://www.rolf-hefti.com/covid-19-coronavirus.html

    Since many of the same criminal establishment “expert” psychopaths, such as Musk (https://archive.ph/9ZNsL) and Harari (Harari is the psychopath affiliated with Schwab’s WEF [https://www.bitchute.com/video/Alhj4UwNWp2m]) or Geoffrey Hinton, the “godfather of AI” who have for many years helped develop, promote, and invest in AI are now suddenly supposedly have a change of heart (they grew a conscience overnight) and warn the public about AI it’s clear their current call for a temporary AI ban and/or its regulation is just a manipulative tactic to misdirect and deceive the public, once again.

    This scheme is part of The Hegellian Dialectic in action: problem-reaction-solution.

    This “warning about AI” campaign is meant to raise public fear/hype panic about an alleged big “PROBLEM” (these psychopaths helped to create in the first place!) so the public demands (REACTION) the governments regulate and control this technology =they provide the “SOLUTION’ FOR THEIR OWN INTERESTS AND AGENDAS… because… all governments are owned and controlled by the leading psychopaths-in-power (see CovidTruthBeKnown.com).

    What a convenient self-serving trickery … of the ever foolish public.

    “AI responds according to the “rules” created by the programmers who are in turn owned by the people who pay their salaries. This is precisely why Globalists want an AI controlled society- rules for serfs, exceptions for the aristocracy.” —Unknown

    “Almost all AI systems today learn when and what their human designers or users want.” —Ali Minai, Ph.D., American Professor of Computer Science, 2023

    express Mohammad Mehrdad Kasiri. I am the lord of the earth and I have seen dozens of miracles from nobles and angels, and I am aware of God’s nature to some extent, and you too, like us, your self cannot easily inform you about why your self cannot inform you, this is because of important issues that I I only know maybe, I am not saying that it is definitely so, supernatural issues are very complicated, whoever asked you to understand the nature of the language of your self-authors and your lords, send a short message to my humble servant’s number, because the self-author, the lord, and the jinn partially activated my email so that I will not be identified. Whoever sends me a message, I will not give my address. This was the expediency of the elders of the world. I mean, it was their wish, but you can read the text below and submit it to NASA scientists. I will send the following message to the address below, all explanations which is related to the destruction of life on earth, the reason for the oil under the coast of the oceans is that in the Persian Gulf, tens of millions of years ago, humans came to the conclusion that they buried the bodies of the dead or the carcasses of aquatic animals in the sea of the Persian Gulf under the ground. Of course, this issue is different from what you Americans believe.
    But I don’t believe that the self-authors and genies, the lords of the earth, have all the secrets of the earthlings who drew the continents and seas in the form of humans and animals tens of millions of years ago.
    I was told this through revelation, as an inspiration, I am unfortunately the only representative of the jinn who receives the frequencies of inspiration and revelation of the jinn and the Lords of the world, and this issue has caused so much difficulty and psychological problems for me that there is no limit. I used to live in an area called Vahidiya, the word Wahi is three alphabets, Wahidiya, but the other three letters of Wahidiya mean money. Of course, for you Latin speakers, the last three letters of Wahidiya mean money for you, but for us Persian speakers, the word Vahidiya means precious blood. The first three letters of the word Wahidiyya are originally composed of two words, which have six letters in Persian, the three letters of which are Wahi, which was revealed to me by the jinn, and the second word, which is the last three letters of the alphabet, Wahidiyya, means precious, which In the translation of the word Wahidiya, the last three letters are the same as money. Now, who should pay the blood price of those who were killed? The people killed by Imam Khomeini from the people and the army should be paid the blood price of everyone who was killed by the mullahs with the sedition and tragedy of the revolution and the assassination of the Shah. All these seditions were caused by the genies, who are the great souls of humans, they told me. The prime ministers of Iran were the same country as England and the countries that planned Iran’s revolution and war with England with radio waves and…..?
    Lords of the earth, why did they name the British country before England, the word England in Persian language means that this country is a parasite and hangs on the countries, why did England dominate the lives and property of the people of Iran and the Muslim countries of the region by combining the religions of the parasites of Mullahs, Sheikhs and Mullahs This is not a joke, why did the queen of England not allow the king to execute the leader of the group of devotees of Islam, whose main members were Khomeini, Seyyed Ali Khamenei, Ali Akbar Rafsanjani, Beheshti and Mohammad Talqani, who were arrested in 1342 and 1343 AH Let Mohammad Reza Shah continue this story in the next days. I, Mohammad Mehr Sahib Zaman, will explain this. God, the jinn, and the lords of the earth told me that now British politics has become a little better and has stopped being evil. Therefore, with the change of the country, England itself. Agreed. Everything is changing on earth. I will say a verse about this from Surah Shukar Shukar.
    (They are changing the land of these owners, the existence of the souls of humans and all the ancestors) Of course, the meaning of this verse may be changed in English, the meaning of God and the jinn are all above you, God bless you in the hope of meeting Dr. Qaim Saheb Zaman. time IN iran 9:37 pm
