Firstly I was writing about quantum mechanical discoveries in photosynthesis many months ago so I dont know why its suddenly news.\n\nAgain, this is not a new discovery, physicists have talked about things which are implicitly quantum mechanical in photosystems. Capturing energy from heat or visible photons is quantum mechanical by nature.\n\nTherefore the comment on mitochondria is spot on. In fact, mitochondria appear to gain energy from heat, and it is not implausible that they were crude photosynthesisers/thermosynthesisers and chemosynthesisers when their ancestors were anaerobic photosynthetic alpha-proteobacteria.\n\nBut the dogma that you cant have room temperature entanglement is long realised (by any good thinker) to be pure hokum and it just does not check out. For example, photons in photosynthetic systems would tend to naturally involve all mannor of entanglement phenomena, as optical physicists and engineers have been discovering (look at optical sensors and computing technology). Because the ammount of energy is not great, boosting efficiency requires ensuring there are systems at the right 'energy state' to receive the quanta of energy available. A 'quantum system' computes within a large network where to put that energy, so that entropy can be directed in a fashion consistent with the fundamental property of life - the entropy generates order. This requires a system of 'entropy direction', which brings us to the following comment in this thread:\n\ncomment:\ncan quantum-based energy transfer be a mechanism of cell protection\nby mabrouk el-sharkawy\n\n[Comment posted 2010-02-03 16:21:33]\n\n"In the course of the complex process of plant photosynthesis , excess of sunlight may cause cellular damages. Perhaps directed energy transfer via waves might enhance cell protection."\n\nOf course, and thats something that must happen in ALL living systems. The genetic system and the metabolic system preserve themselves via quantum interactions. It is not only proposed on line by myself before this, it also is proposed that life has to evolve via a system of controlled entropy and that this selects for quantum mechanical properties that assist this, in the adoption of each cell molecule, especially those that are 'metabolic' because this is where the entropy is. To help define this I coin the term 'quantum selection' which means that the highest ordered structures in the cells survive against entropy only by quantum interactions that 'throw off' damaging molecular-energy interactions that would otherwise destroy these complex networks (destroy the order, which represents the cell). The complexity in life is actually fundamentally dependent on having 'quantum' properties that allows energy that is destructive to cascade through metabolic systems, which predate photosynthetic systems and are based on accelerations of natural entropy in hydrochemistry in the crust. The entropy is thereby directed by making the entropic system sacrificial but by making the ordered system selectively invisible. This again is a system requirement for life, and reflects the properties of 'quantum' materials.\n\nSo, the molecules selected by life are partly selected because they can 'cooperate' and 'hide' from entropic forces, and utilise the entropy within the cell to boost back cell repair of the complex system. This spells the ability of these components to selectively tune to each other and this process is essentially what happens on quantum mechanics. Life is based on preservation of complexity that itself cooperates to this end, so it leads to a selection of interactional, theregore ' quantum mechanical' properties in these cell components. These cell components are the order and the information and the machinery of the cell, they are entropy converters, but they must AVOID entropy themselves: the best way to do that is to have properties where interactions divert forces of entropy ie photons away from the desired ordered structures, and to use the more interactional structures as 'entropy acceptors' which in turn become the recognised bits of the metabolic system ie the electron transport chain. Quantum phenomena are essentially merely the result of given components selectively interacting (exchanging energy) to particular others. This is not caused by adding entanglement but actually by taking it away - hence, entanglement is a process of isolation and transfer, in which those 'resonant' components are able to transfer energy rapidly to each other, thereby avoiding the physical consequences of accepting the energy themselves. Quantum entanglement is essentially a preferential instantaneous 'entropy network' that reduces internal topographical changes by switching out energy, but also allows the network to ignore energy it isn't in the condition to interact with as a group, otherwise would ammount to molecular events and manifestation of fields that spread out interaction with other things. This process results in the weirdness of things like superconductors, which reject interaction with magnetic fields. Once a certain ammount of interaction is forced, quantum properties ie superconductivity, fail and fail very rapidly through heating and conformational changes in the material. Below that threshold the behavior looks weird and magical, because the entanglement is actually selective and more limited (but more effective at transfering energy) than in the surrounding non-weird materials which we model as classical, and which are not 'living'. \n\nAnd, this ability to select out things that dont interact with the 'group', unless the interaction is suitably violent, is based on the properties of the group 'members' to interact in such away to move entropy away. This means that in evolving materials, where order is to increase in spite of the energy, there is a need for each component to be selected in terms of its ability to assist this cooperation and this means its quantum mechanical abilities and its cooperation are intrinsically related and are increasing properties in any evolving system of this type.
