I use the term ‘Spiritual’ to describe relationships between entities based upon shared values, feelings, thoughts, interests, and purpose. Living Cell is Building Block of Life. Its primary purpose in Life is Generation and Propagation of entities of its own kind to sustain its existence. To perform such living functions, Cell requires energy input from its external environment. The Spiritual Dimension of Living Cell involves its ability to acquire energy from an external source. In Physiology, the term ‘NUTRITION’ describes the Power of Living Cell to attract matter (or energy yielding molecules) from its external environment. The issue that concerns me is that of Origin or Beginning of this Power of Nutrition.

The Concept of Last Universal Common Ancestor (LUCA) proposes random, unguided, unpurposive, events causing goal-oriented generation of mechanisms to establish relationship, partnership, association, bonding, or cooperation between energy yielding molecules of Nonliving Matter and energy demanding molecules of Living Matter.

Last common ancestor of life on Earth came from ancient oceans.DJ / Fotolia A four billion-year-old mystery surrounding the one common ancestor of all life on Earth has been solved by scientists.
All life evolved from a single-celled organism known as life’s Last Universal Common Ancestor (LUCA). However, few details are known about what it looked like, how it lived and how it evolved.
Now scientists at University College London (UCL) have discovered that LUCA had a “leaky membrane” which allow it to absorb energy from light, while still holding the other components necessary for life inside it.
Researchers discovered this by modelling how the LUCA’s membrane changed to enable its descendants to move to more challenging environments, and eventually evolve into two distinct types of single-celled organisms: bacteria and archaea.
Data suggests LUCA lived in ancient seawater where liquid dense with protons (sub-atomic particles positively charged with electricity) mixed with warm alkaline fluid from vents which had fewer protons.
The difference in concentrations allowed protons to flow into the cell, which led to the production of a molecule called ATP. This transfers energy through a cell, powering its growth.
Ion pumping (which enables cells to store energy) and phospholipid membranes (cell walls made of fat cells) evolved independently in archaea and bacteria.However, experts say this could only have happened if the membrane was ‘leaky’ – in that it allowed protons to leave the cell spontaneously, so more could enter to boost growth.
The study’s leader Nick Lane said: “In these deep sea vents, there is a continuous flow of alkaline fluids which mix with the ocean waters. When they mix, the fluids neutralise each other, and that stops any build-up of charge which would otherwise prevent protons flowing into the cell.
“If the first cells had leaky membranes, then protons could enter and then be neutralised, or leave again, almost as if there was no barrier at all. What we’ve shown is that the rate at which protons enter and leave is high enough to power the growth of cells via proteins embedded in the membrane.
“So LUCA could have been powered by natural proton gradients in vents, but only if it had a really leaky membrane, completely unlike today’s cells.”
Victor Sojo, the first author of the study, said: “Exploiting gradients is universal across all life, but understanding how LUCA used one to drive growth gave us a bit of a chicken-and-egg problem: LUCA wouldn’t make a gradient if it didn’t know how to exploit it, but how could it learn how to exploit a gradient if it didn’t make one in the first place? We propose that natural proton gradients provide a solution because LUCA didn’t have to make the gradient; it was already there for free.”
The study was published in the journal PLoS Biology

I seek harmony between doctrines of Idealism and Realism to account for human existence. I welcome thoughts from all directions to understand the nature of Human Identity and Individuality. The multicellular human organism exists as Physical, Mental, Social, Moral, Spiritual being with a Creative Form that cannot be duplicated. For purposes of brevity and simplicity, I divide the human being into two categories; 1. The first is 'SELF' and it represents man as Physical, Mental, and Social Being and 2. The second is, the 'KNOWING-SELF' which represents man as Moral, Rational and Spiritual Being."I am Consciousness, therefore I am", is the proposition that I use to understand the nature of man's Identity and Individuality. Man is a Mortal Being whose Life and Death are operated by Oxidation-Reduction Chemical Reactions. The Physical Being is dissolved by the powerful influence of Time which seem to operate Natural Law of Aging. Things in Nature change with Time but the Identity and Individuality of Man remains the same during his Life Journey. The genotype remains unchanged while the phenotype appears to be changing all the time. In the multicellular human organism, the Consciousness functions to establish Identity of the organism and to defend its Individuality. Consciousness also establishes the Connection, Partnership, Relationship, Yoking, Joining, and Association between the energy dependent man and his energy provider. Man exists in Nature because of his ability to acquire energy from external environmental source. Consciousness in its essence refers to this awareness of energy dependence. I describe the Connection between energy seeker and energy provider as 'God Connection'. Man during all the stages of his existence, and under any given circumstance, either in good health, or ill-health exists on the basis of this 'God Connection' which is an attribute of biological or living function called Consciousness. This conditioned nature of human existence is supported by Power/Energy/Force which can be experienced as Compassion/Mercy/Grace of the Creator who created man as an Individual with unique genome that has never existed in the past and also will never exist in the future. I seek the Unity of Man in Body, Mind, and Soul unlike other common Indian traditions that seek to verify Identity between Human Soul and Divine Soul. My doctrine can be described as Unity Theory of Non-Dualism.
