The recent discovery of warm-temperature quantum vibrations in microtubules inside brain neurons by the research group led by Anirban Bandyopadhyay, PhD, at the National Institute of Material Sciences in Tsukuba, Japan (and now at MIT), corroborates the pair’s theory and suggests that EEG rhythms also derive from deeper level microtubule vibrations.
In addition, work from the laboratory of Roderick G. Eckenhoff, MD, at the University of Pennsylvania, suggests that anesthesia, which selectively erases consciousness while sparing non-conscious brain activities, acts via microtubules in brain neurons.
It was once purported that biological systems were far too ‘warm and wet’ to support quantum phenomena mainly owing to thermal effects disrupting quantum coherence. However, recent experimental results and theoretical analyses have shown that thermal energy may assist, rather than disrupt, quantum coherent transport, especially in the ‘dry’ hydrophobic interiors of biomolecules. Specifically, evidence has been accumulating for the necessary involvement of quantum coherent energy transfer between uniquely arranged chromophores in light harvesting photosynthetic complexes. The ‘tubulin’ subunit proteins, which comprise microtubules, also possess a distinct architecture of chromophores, namely aromatic amino acids, including tryptophan. The geometry and dipolar properties of these aromatics are similar to those found in photosynthetic units indicating that tubulin may support coherent energy transfer. Tubulin aggregated into microtubule geometric lattices may support such energy transfer, which could be important for biological signalling and communication essential to living processes. Here, we perform a computational investigation of energy transfer between chromophoric amino acids in tubulin via dipole excitations coupled to the surrounding thermal environment. We present the spatial structure and energetic properties of the tryptophan residues in the microtubule constituent protein tubulin. Plausibility arguments for the conditions favouring a quantum mechanism of signal propagation along a microtubule are provided. Overall, we find that coherent energy transfer in tubulin and microtubules is biologically feasible.
Third, YOU HAVE THE AUDACITY TO COMPLAIN THAT HAMEROFF'S WEBSITE IS TALKING ABOUT THESE THINGS. ARE YOU SERIOUS????
Hameroff is presenting research on his website that pertains to the quantum mind. Just like if you go to Alan Guth's website you will find talk about inflation.
The Intelligent Plant. That is the title of a recent article in The New Yorker — and new research is showing that plants have astounding abilities to sense and react to the world.
But can a plant be intelligent? Some plant scientists insist they are — since they can sense, learn, remember and even react in ways that would be familiar to humans.
Michael Pollan, author of such books as "The Omnivore's Dilemma" and "The Botany of Desire," wrote the New Yorker piece about the developments in plant science. He says for the longest time, even mentioning the idea that plants could be intelligent was a quick way to being labeled "a whacko." But no more, which might be comforting to people who have long talked to their plants or played music for them.
The new research, he says, is in a field called plant neurobiology — which is something of a misnomer, because even scientists in the field don't argue that plants have neurons or brains.
"They have analagous structures," Pollan explains. "They have ways of taking all the sensory data they gather in their everyday lives ... integrate it and then behave in an appropriate way in response. And they do this without brains, which, in a way, is what's incredible about it, because we automatically assume you need a brain to process information."

You materialist are so hypocritical.
Quantum computing could revolutionize the way we interact with information. Such systems would process data faster and on larger scales than even the most super of supercomputers can handle today. But this technology would also dismantle the security systems that institutions like banks and governments use online, which means it matters who gets their hands on a working quantum system first.
Just last week I wrote about how a team of researchers in the Netherlands successfully teleported quantum data from one computer chip to another computer chip, a demonstration that hinted at a future in which quantum computing and quantum communications might become a mainstream reality.
That still seems a long way off—physicists agree that transmitting quantum information, though possible, is unstable. And yet! The U.S. Army Research Laboratory today announced its own quantum breakthrough.
A team at the lab's Adelphi, Maryland, facility says it has developed a prototype information teleportation network system based on quantum teleportation technology. The technology can be used, the Defense Department says, to transmit images securely, either over fiber optics or through space—that is, teleportation in which data is transmitted wirelessly.
The DoD says it can imagine using this kind of technology so military service members can securely transmit intelligence—photos from "behind enemy lines," for instance—back to U.S. officials without messages being intercepted.
But this kind of technological advance, especially in a government-run lab, is significant for the rest of us, too. Quantum computing would offer unprecedented upgrades to data processing—both in speed and scope—which could enhance surveillance technologies far beyond what exists today.
Quantum biology: On the face of it, quantum effects and living organisms seem to occupy utterly different realms. The former are usually observed only on the nanometre scale, surrounded by hard vacuum, ultra-low temperatures and a tightly controlled laboratory environment. The latter inhabit a macroscopic world that is warm, messy and anything but controlled. A quantum phenomenon such as 'coherence', in which the wave patterns of every part of a system stay in step, wouldn't last a microsecond in the tumultuous realm of the cell.
Or so everyone thought. But discoveries in recent years suggest that nature knows a few tricks that physicists don't: coherent quantum processes may well be ubiquitous in the natural world. Known or suspected examples range from the ability of birds to navigate using Earth's magnetic field to the inner workings of photosynthesis — the process by which plants and bacteria turn sunlight, carbon dioxide and water into organic matter, and arguably the most important biochemical reaction on Earth.
Me: Perhaps this is evidence of a "natural" simulation, completely controlled, with biological parameters set.
More from article:
Researchers have long suspected that something unusual is afoot in photosynthesis. Particles of light called photons, streaming down from the Sun, arrive randomly at the chlorophyll molecules and other light-absorbing 'antenna' pigments that cluster inside the cells of every leaf, and within every photosynthetic bacterium. But once the photons' energy is deposited, it doesn't stay random. Somehow, it gets channelled into a steady flow towards the cell's photosynthetic reaction centre, which can then use it at maximum efficiency to convert carbon dioxide into sugars.
Since the 1930s, scientists have recognized that this journey must be described by quantum mechanics, which holds that particles such as electrons will often act like waves. Photons hitting an antenna molecule will kick up ripples of energized electrons — excitons — like a rock splashing water from a puddle. These excitons then pass from one molecule to the next until they reach the reaction centre. But is their path made up of random, undirected hops, as researchers initially assumed? Or could their motion be more organized? Some modern researchers have pointed out that the excitons could be coherent, with their waves extending to more than one molecule while staying in step and reinforcing one another.
“Nature knows a few tricks that physicists don't.”
If so, there is a striking corollary. Coherent quantum waves can exist in two or more states at the same time, so coherent excitons would be able to move through the forest of antenna molecules by two or more routes at once. In fact, they could simultaneously explore a multitude of possible options, and automatically select the most efficient path to the reaction centre.
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thought it could help them harvest energy from the sun much more efficiently. Working out its role in a living organism could lead to technological advances, such as better organic solar cells and quantum-based electronic devices.
The research is published in the journal Proceedings of the National Academy of Sciences.
It is part of an emerging field called quantum biology, in which evidence is growing that quantum phenomena are operating in nature, not just the laboratory, and may even account for how birds can navigate using the earth's magnetic field.

Interesting. And coincidental. I was just reading about coherence a day or so ago. Who knows anymore when? LOL
Where is it you are repeating yourself, as I was doing most of the posting? There's a lot of jumping up and down and yelling, and there is more than one unfair advantage in play, at the same time, which makes it hard to understand why the jumping up and down and yelling. That unfair advantage is providing nothing but proof of this theory, whatever subject is brought up and it is applied to. That speaks volumes about the unfair advantage. But it's more obfuscation, really, of the very thing supplying the unfair advantage so that the theory can be denied. What an irony. I suppose that irony is completely lost on those jumping up and down and yelling. Denying the truth just because you don't like where it's coming from doesn't make it any less true, no matter where it comes from. And that truth is giving you the chance to deny it. That's an explanation of the irony, btw, in case its lost in translation.
So in the spring of 2007 when the New York Times reported that green sulphur-breathing bacteria were performing quantum computations during photosynthesis, my colleagues and I laughed. We thought it was the most crackpot idea we had heard in a long time. Closer examination of the paper, published in Nature, however, showed that something decidedly non-crackpot was going on.
By zapping complexes of photosynthetic molecules with lasers, the authors of the paper were able to show that the excitons use quantum mechanics to make their journey through the photocomplex more efficient. The experimental evidence was strong and compelling. The authors also speculated that the excitons were performing a particular quantum computation algorithm called a quantum search, in which the wave-like nature of propagation allows the excitons to zero in on their target. As it turns out, the excitons were performing a different kind of quantum algorithm called a quantum walk, but the “crackpot” fact remained: Quantum computation was helping the bacteria move energy from point A to point B.
How could tiny bacteria be performing the kind of sophisticated quantum manipulations that it takes human beings a room full of equipment to perform? Natural selection is a powerful force. Photosynthetic bacteria have been around for more than a billion years, and during that time, if a little quantum hanky panky allowed some bacteria to process energy and reproduce more efficiently than other bacteria, then quantum hanky panky stuck around for the next generation. Nature is also the great nanotechnologist. Living systems operate on the basis of molecular mechanisms, where atoms and energy are channeled systematically through molecular complexes within the cell. The molecules in turn are assembled using the laws of quantum mechanics—quantum weirdness is always lurking just around the chemical corner. These quantum changes can either help or hinder energy transport. Natural selection ensures that the role of quantum weirdness in cellular energy transport is a beneficial one.
Together with Alan Aspuru-Guzik and Patrick Rebentrost at Harvard, my MIT colleague Masoud Mohseni and I constructed a general theory of how quantum walks in photosynthesis can use the wavelike nature of quantum mechanics to attain maximum efficiency. It turns out that wavelike transport is not always the best strategy. To understand why, suppose that the lilypond is full of rocks sticking up out of the water. As the wave moves through the pond, it scatters off the rocks. As a result, the wave never reaches the middle of the pond, which remains calm and protected. This is a phenomenon called destructive interference. Although the wave can propagate a short distance, eventually the random waves scattered off the rocks interfere with the overall wave’s propagation, effectively stopping it in its tracks. The quantum frog becomes completely stuck: A classical hopping strategy would have been more efficient. In the antenna photocomplex, the “rocks” are microscopic irregularities and molecular disorder that scatter the quantum wave as it tries to pass through.
By constructing detailed quantum mechanical models, my collaborators and I were able to identify the optimal strategy for the interplay between wavelike propagation and classical hopping in photosynthesis. Over short distances, the wavelike propagation is more effective than random hopping. The exciton travels like a wave right up to the distance at which destructive interference causes it to get stuck. At this point, the fact that living systems are hot, wet environments comes into play: The environment effectively gives the exciton a whack that gets it unstuck and makes it perform a classical hop, which frees up the exciton to propagate again. (The technical term for this whack is “decoherence.”) Then the process repeats. The wave propagates until it gets stuck; the environment gives it a whack; the exciton hops. Eventually, the exciton reaches the reaction center in the minimum possible time. Expressed in terms of our quantum frog, the rule is simple: Wave until you get stuck, then hop.

Your whole post is just nonsense.
