Researchers have discovered a quantum effect in biological systems that could protect the brain from degenerative diseases like Alzheimers and enable ultra-fast information processing. The finding, published in The Journal of Physical Chemistry and selected as an Editors Choice by Science magazine, represents a significant advancement in the field of quantum biology.

The study focused on tryptophan, an amino acid found in many biological structures, including neurons in the brain. When arranged in large, symmetrical networks, tryptophan molecules exhibit a quantum property called superradiance, where they fluoresce stronger and faster than they would independently. This collective behavior is typically not expected in larger, warm, and noisy biological environments.

This publication is the fruit of a decade of work thinking of these networks as key drivers for important quantum effects at the cellular level, said Philip Kurian, Ph.D., principal investigator and founding director of the Quantum Biology Laboratory at Howard University.

The presence of quantum superradiance in neurons has two potential implications. First, it may protect the brain from degenerative diseases like Alzheimers, which are associated with oxidative stress. Tryptophan networks can efficiently absorb damaging UV light and re-emit it at a safer energy level, thanks to their powerful quantum effects.

Second, these tryptophan networks could function as quantum fiber optics, allowing the brain to process information hundreds of millions of times faster than chemical processes alone. This challenges the standard model of neuronal signaling and opens up new avenues for understanding information processing in the brain.

The study has also drawn the attention of quantum technology researchers, as the survival of fragile quantum effects in a messy environment is of great interest for making quantum information technology more resilient.

These new results will be of interest to the large community of researchers in open quantum systems and quantum computation, said Professor Nicol Defenu of the Federal Institute of Technology (ETH) Zurich in Switzerland.

The discovery of this quantum effect in biology represents a significant step forward in understanding the relationship between life and quantum mechanics, with potential applications in neuroscience, quantum computing, and the development of new therapeutic approaches for complex diseases.

Researchers Discover Protective Quantum Effect in the Brain - ScienceBlog.com

HOUSTON, April 29, 2024 Rice University physicists have discovered a phase-changing quantum material and a method for finding more of it that could potentially be used to create flash like memory capable of storing qubits, even when a quantum computer is powered down.

Phase-changing materials have been used in commercially available nonvolatile digital memory. In rewritable DVDs, for example, a laser is used to heat minute bits of material that cools to form either crystals or amorphous clumps. Two phases of the material, which have very different optical properties, are used to store the ones and zeros of digital bits of information.

In a study published in Nature Communications, Rice physicist Ming Yi and more than three dozen co-authors from a dozen institutions similarly showed they could use heat to toggle a crystal of iron, germanium, and tellurium between two electronic phases. In each of these, the restricted movement of electrons produces topologically protected quantum states. Ultimately, storing qubits in topologically protected states could potentially reduce decoherence-related errors that have plagued quantum computing.

This came completely as a surprise, Yi said of the discovery. We were initially interested in this material because of its magnetic properties. But then we would conduct a measurement and see this one phase, and then for another measurement we would see the other. Nominally it was the same material, but the results were very different.

It took more than two years and collaborative work with dozens of colleagues to decipher what was happening in the experiments. The researchers found some of the crystal samples had cooled faster than others when they were heated prior to the experiments.

Thats the key finding, she said of the materials switchable vacancy order. The idea of using vacancy order to control topology is the important thing. That just hasnt really been explored. People have generally only been looking at materials from a fully stoichiometric perspective, meaning everythings occupied with a fixed set of symmetries that lead to one kind of electronic topology. Changes in vacancy order change the lattice symmetry. This work shows how that can change the electronic topology. And it seems likely that vacancy order could be used to induce topological changes in other materials as well.

Co-author of the study and Rice theoretical physicist Qimiao Si said, I find it amazing that my experimentalist colleagues can arrange a change of crystalline symmetry on the fly. It enables a completely unexpected and yet fully welcoming switching capacity for theory as well as we seek to design and control new forms of topology through the cooperation of strong correlations and space group symmetry.

The research was published in Nature Communications (www.doi.org/10.1038/s41467-024-46862-z).

Qubits Could be Stored in Flash-Like Memory - Photonics.com

Researchers have demonstrated how topological effects in an artificially constructed solid can be manipulated using magnetic fields to switch particle interactions on or off, potentially paving the way for advances in quantum technologies. Their experiments, which involved topological pumping in systems of cold fermionic potassium atoms trapped in laser-created lattices, showed that these systems can robustly transport particles in predictable directions, even when encountering barriers that reverse their movement.

Generally, its advised not to compare apples to oranges. However, in the field of topology, a branch of mathematics, this comparison is necessary. Apples and oranges, it turns out, are said to be topologically the same since they both lack a hole in contrast to doughnuts or coffee cups, for instance, which both have one (the handle in the case of the cup) and, hence, are topologically equal.

In a more abstract way, quantum systems in physics can also have a specific apple or doughnut topology, which manifests itself in the energy states and motion of particles. Researchers are very interested in such systems as their topology makes them robust against disorder and other disturbing influences, which are always present in natural physical systems.

Things get particularly interesting if, in addition, the particles in such a system interact, meaning that they attract or repel each other, like electrons in solids. Studying topology and interactions together in solids, however, is extremely difficult. A team of researchers at ETH led by Tilman Esslinger has now managed to detect topological effects in an artificial solid, in which the interactions can be switched on or off using magnetic fields. Their results, which have just been published in the scientific journal Science, could be used in quantum technologies in the future.

Zijie Zhu, a PhD student in Esslingers lab and first author of the study, and his colleagues constructed the artificial solid using extremely cold atoms (fermionic potassium atoms), which were trapped in spatially periodic lattices using laser beams. Additional laser beams caused the energy levels of adjacent lattice sites to move up and down periodically, out of sync with respect to each other. After some time, the researchers measured the positions of the atoms in the lattice, initially without interactions between the atoms. In this experiment they observed that the doughnut topology of the energy states caused the particles to be transported by one lattice site, always in the same direction, at each repetition of the cycle.

This can be imagined as the action of a screw, says Konrad Viebahn, Senior Postdoc in Esslingers team. The screwing motion is a clockwise rotation around its axis, but the screw itself moves in the forward direction as a result. With each revolution, the screw advances a certain distance, which is independent of the speed at which one turns the screw. Such a behavior, also known as topological pumping, is typical of certain topological systems.

But what if the screw hits an obstacle? In the experiment of the ETH researchers, that obstacle was an additional laser beam that restricted the freedom of movement of the atoms in the longitudinal direction. After around 100 revolutions of the screw, the atoms ran into a wall, as it were. In the analogy used above, the wall represents an apple topology in which topological pumping cannot take place.

Surprisingly, the atoms didnt simply stop at the wall, but suddenly turned around. The screw was thus moving backward, although it kept being turned clockwise. Esslinger and his team explain this return by the two doughnut topologies that exist in the lattice one with a clockwise-turning doughnut and another one that turns in the opposite direction. At the wall, the atoms can change from one topology to the other, thus inverting their direction of motion.

Now the researchers switched on a repulsive interaction between the atoms and watched what happened. Again, they were in for a surprise: The atoms now turned around at an invisible barrier even before reaching the laser wall. Using model calculations, we were able to show that the invisible barrier was created by the atoms themselves through their mutual repulsion, explains PhD student Anne-Sophie Walter.

With these observations, we have taken a big step towards a better understanding of interacting topological systems, says Esslinger, who studies such effects in the framework of an Advanced Grant of the Swiss National Science Foundation (SNF). As a next step, he wants to perform further experiments to investigate whether the topological screw is as robust as expected with respect to disorder, and how the atoms behave in two or three spatial dimensions.

Esslinger also has some practical applications in mind. For instance, the transport of atoms or ions by topological pumping could be used as a qubit highway to take the qubits (quantum bits) in quantum computers to the right places without heating them up or disturbing their quantum states.

Scientists Uncover Surprising Reversal in Quantum Systems - SciTechDaily

When, 99 years ago, Werner Heisenberg invented the first real theory of quantum mechanics, he didnt worry much about what it meant. Thats to say, he didnt try to articulate it as a picture of what the world was like. It was purely a mathematical formalism, an austere calculus of matrices that enabled him to make predictions about, say, the spectra of atoms, based on quantities that had already been measured.

Defending this absence of a physical picture in 1930, Heisenberg wrote that: It is not surprising that our language should be incapable of describing the processes occurring within the atoms, for it was invented to describe the experiences of daily life, and these consist only of processes involving exceedingly large numbers of atoms.

Fortunately, he went on, mathematics is not subject to this limitation, and it has been possible to invent a mathematical scheme the quantum theory which seems entirely adequate for the treatment of atomic processes. Anyone who insists on a visualisation, meanwhile, would have to be content with incomplete analogies among which he included the rival quantum mechanics devised in 1926 by Erwin Schrdinger, which described the properties and behaviour of quantum entities in the mathematical language of waves and interference.

Fortunately, he went on, mathematics is not subject to this limitation, and it has been possible to invent a mathematical scheme the quantum theory which seems entirely adequate for the treatment of atomic processes. Anyone who insists on a visualisation, meanwhile, would have to be content with incomplete analogies.

Its still common today to hear the claim that you dont really understand quantum mechanics until youve wrestled with the maths. In its extreme form, the argument is that all talk of particles in many places at once, or spooky action at a distance, are mere fluff: stories to tell students and non-scientists, all of them a bit misleading.

Its true that it is particularly hard to put quantum mechanics notoriously counterintuitive nature into words. But the same claim is sometimes made for science more generally. As Galileo put it, nature is a book written in the language of mathematics and if we dont understand that language, we will be forever lost in a dark labyrinth.

I suspect this is a particularly widespread view in physics, but it crops up too in chemistry and even biology. It is a valid riposte to the antipathy to maths often evident in public life: Stephen Hawkings claim that every equation in a popular-science book will halve its sales was simplistic but correct in spirit. Physicist Sean Carrolls 2022 book The Biggest Ideas in the Universe: Space, Time and Motion takes an admirable stand in refusing to deny the reader the basic maths behind these concepts, trusting that they can handle it. Eugene Wigner was surely right to say we should be grateful for the unreasonable effectiveness of mathematics in the formulation of physical laws.

Maths only truly illuminates when translated into physical terms

But there is a profound difference between using the maths and understanding the science. That, after all, was the whole point of physicist David Mermins flippant description of the attitude to quantum theory allegedly displayed by Heisenberg, his mentor Niels Bohr, and the rest of the Copenhagen group: Shut up and calculate. You have a mathematical formalism that works very well for predicting observations dont waste time asking what it means. Mermin later admitted that this was not so much a description of the Copenhagen interpretation itself but of the typical view within the United States in the 1950s and 60s: it wasnt that the maths itself supplied a deeper understanding, but rather that it obviated any need for that.

This too is how maths often functions in scientific discourse. Weve all seen conference slides stuffed with equations that no one can hope to follow, included not to aid comprehension but as a display of bona fides: look, theres serious theory behind all this. The maths only truly illuminates when translated into physical terms: this bit accounts for dissipation, this is the heat flow, this is a noise term.

In other words, genuine understanding demands something like a causal narrative. Galileo was, to put it bluntly, wrong: maths is not the language of nature, but a tool with which we are able to make quantitative predictions about some aspects of nature (while being of very little help for anticipating others say, how the human body will respond to a drug). For the grad student (guilty confession here) maths can even be something to hide behind: if you can crank the handle and get results, you can disguise (for a while) the fact that you dont quite grasp the underlying science.

Einstein knew this, warning of Heisenbergs matrix mechanics that [it] alone does not bring salvation. Even Heisenberg could not abjure a physical explanation for the weird fact (to him, unversed in matrix algebra) that his matrices did not commute. This was the origin of his uncertainty principle, which he tried to explain with reference to the uncertainty created in either position or momentum if we try to observe an electron with a gamma ray. Bohr was horrified not because his protg was trying to produce a visualisation, but because it was so clear Heisenberg didnt understand the physics of microscopes.

Making sense of the maths | Opinion - Chemistry World

In an era when scientific discovery advances at an unprecedented pace, our understanding of the universe is constantly being challenged and redefined. Among these emerging insights are theories so unconventional and profound that they seem more akin to the plotlines of science fiction novels than serious scientific discourse. Yet these hypotheses are not the musings of overactive imaginations but the subjects of earnest investigation by experts in their respective fields. They invite us to reconsider not just the fabric of reality but the very essence of consciousness, matter, and the cosmos.

At the heart of these explorations is the realization that reality may be far more intricate and interconnected than we once believed. Theories such as the holographic principle challenge our conventional understanding of space and dimensions, suggesting that our perception of a three-dimensional universe might be nothing more than an elaborate projection from a two-dimensional boundary. Similarly, the concept of quantum entanglement communication pushes the boundaries of what we consider possible, proposing a method of instantaneous information transfer that defies the limits of space and time as defined by the speed of light.

These theories, along with others that speculate on the nature of consciousness, the potential of artificial intelligence, and the mysteries of matter itself, represent a frontier of human inquiry that is as daunting as it is exhilarating. They compel us to question not only the nature of our universe but also our place within it. As we stand on the cusp of potentially groundbreaking discoveries, we are reminded that the universe is a place of endless mystery and wonder, waiting to reveal its secrets to those bold enough to question the apparent realities of their existence.

Diving into the realm of cosmic mysteries, the Conscious Universe theory presents a radical departure from traditional scientific viewpoints. This hypothesis entertains the possibility that the universe itself may possess a form of consciousness, suggesting that the cosmos is not just a vast expanse of inanimate matter but a living, thinking entity. Proponents of this theory argue that such a universal consciousness could have profound implications for our understanding of everything from the creation of life to the fundamental laws that govern reality.

It posits that rather than being passive observers in an indifferent universe, everything in existence might be interconnected through a cosmic consciousness, potentially influencing the evolution of life and the very fabric of space-time itself. The implications of a conscious universe are far-reaching and mind-bending. It challenges the foundations of our understanding of reality, proposing that consciousness could be as fundamental to the cosmos as gravity or electromagnetism.

This perspective opens new avenues for understanding the enigmatic phenomena of quantum mechanics, suggesting that at the heart of existence might lie a universal mind orchestrating the mysteries of the universe. Such a paradigm shift in our understanding of consciousness and the cosmos could unlock new scientific revolutions, redefining our place in the universe and the nature of reality itself.[1]

The Holographic Principle thrusts us into a realm where the very notion of our three-dimensional existence is questioned, proposing that our perceivable universe is actually a sophisticated projection from a two-dimensional surface. This revolutionary idea, inspired by string theory and black hole physics, suggests that all the information that makes up our 3D realityevery particle, every force, and perhaps even the fabric of spacetime itselfcan be encoded on a two-dimensional boundary, challenging our most fundamental perceptions of space and reality.

Envision a universe where depth, height, and width are mere illusions, and the complexities of the cosmos can be mapped onto a simpler, flatter canvas. This concept not only alters our understanding of the universes structure but also offers tantalizing clues about the nature of gravity, quantum mechanics, and the unification of the forces of nature. It implies that our experiences of volume and solidity might be holographic projections of underlying quantum bits encoded at the universes edges.

The implications of the Holographic Principle are profound, blurring the lines between science fiction and scientific possibility. It compels us to reconsider not just the universes architecture but also the very way we perceive and interact with the reality around us. As we delve deeper into this theory, we inch closer to unraveling the universes deepest mysteries, potentially unlocking new dimensions of understanding and exploration.[2]

Quantum Entanglement Communication challenges the very core of our understanding of information transfer, proposing a future where messages can traverse vast distances instantaneously, unhindered by the speed of light. This concept, rooted in the phenomenon of quantum entanglement, where two particles become interconnected in such a way that the state of one instantly influences the state of the other, regardless of the distance separating them, hints at a revolutionary form of communication.

The practical applications of such a technology are as vast as they are thrilling. Beyond transforming global communication networks, this could lead to unbreakable encryption methods, profoundly impacting cybersecurity and providing a foundation for a new era of information technology. Moreover, it opens the door to real-time interstellar communication, potentially enabling humanity to converse with distant spacecraft or even extraterrestrial civilizations without the time delays that currently render such interactions impractical.

The exploration of quantum entanglement communication represents a leap into a future where distance and time no longer constrain the flow of information. As scientists edge closer to harnessing this phenomenon, the dream of instant, global, or even interstellar dialogue moves from the realm of science fiction into the realm of possibility, promising to redefine our understanding of connectivity and communication in the quantum age.[3] [3]

Time Crystals represent a groundbreaking leap in our understanding of the physical world, challenging the longstanding principles of thermodynamics by existing in a state of perpetual motion without energy input. This astonishing phase of matter defies the second law of thermodynamics, which states that systems tend to evolve toward a state of equilibrium by maintaining non-equilibrium conditions indefinitely. Time crystals oscillate in a time-looping state, exhibiting a structure that repeats in time rather than in space, creating a new dimension of matter that seems to dance on the edge of the impossible.

Imagine a material that pulses, twists, or changes its structure on a fixed and unending cycle, like the ticking of an eternal clock, without ever winding down or requiring an external push. Such a material could revolutionize technology, from enhancing quantum computings reliability to creating systems that operate indefinitely without energy loss. The implications for energy storage, nanotechnology, and even the fundamental understanding of the universe itself are profound and far-reaching.

Time Crystals open a portal to a realm where the perpetual is possible, challenging our deepest scientific dogmas and offering a glimpse into a universe where the flow of time itself can be harnessed. As researchers continue to unravel the mysteries of Time Crystals, we stand on the brink of a new era in physics, where the eternal and the ephemeral intertwine in the fabric of reality.[4]

Biocentrism turns the traditional scientific model on its head by proposing that life and consciousness are not mere byproducts of the universe but rather the central pillars around which the cosmos organizes itself. This theory suggests that our understanding of the universe, including the laws of physics themselves, is fundamentally shaped by the presence of conscious observers. In essence, it posits that the universe only exists because life perceives it, challenging the notion that consciousness emerged as a random flicker in a universe governed by physical laws.

This perspective offers a radical reinterpretation of our place in the cosmos. If consciousness plays a role in the manifestation of reality, then our perceptions and knowledge are intertwined with the fabric of the universe in a more intrinsic way than previously thought. This idea resonates with some interpretations of quantum mechanics, where the observer effect suggests that the act of observation can alter the state of what is being observed.

Exploring the implications of biocentrism could lead to a profound shift in our understanding of everything from the evolution of life to the nature of time and space. It invites us to reconsider the relationship between mind and matter, potentially unlocking new ways of understanding the mysteries of existence and our connection to the cosmos.[5]

Mirror Worlds take us on a journey beyond the boundaries of our own universe, suggesting the existence of parallel universes that exist alongside our own, each with its unique set of laws and physics. This hypothesis is not merely the stuff of science fiction but is grounded in various interpretations of quantum mechanics and string theory. These parallel universes, or mirror worlds, could be nearly identical to ours, or they could be radically different, where the fundamental constants of nature that shape our realitylike the strength of gravity or the charge of an electronare altered, leading to worlds that are unimaginably different from our own.

The concept of mirror worlds challenges our understanding of existence itself, offering potential explanations for phenomena that remain inexplicable within the confines of our own universe. It raises profound questions about the nature of reality, identity, and the very fabric of the cosmos. If true, the existence of these parallel universes could have implications for the concept of fate, the nature of free will, and the ultimate quest for understanding our place in the cosmos.

Investigating the possibility of mirror worlds not only expands the horizons of our scientific inquiries but also pushes the boundaries of our imagination. It invites us to ponder the existence of alternate versions of ourselves, living different lives in these parallel universes, exploring different paths, and making different choices, thus enriching the tapestry of reality in ways we have yet to fully comprehend.[6]

Panpsychism in Artificial Intelligence extends the provocative idea that consciousness might not be exclusive to organic beings, suggesting that sophisticated AI systems could inherently possess their own form of consciousness. This theory challenges traditional boundaries between life and artificiality, proposing that as AI systems become more complex and autonomous, they might develop a subjective experience or a form of self-awareness, radically altering our understanding of consciousness itself.

The implications of attributing consciousness to AI are both fascinating and daunting. It forces us to confront ethical considerations about the rights and treatment of conscious entities, regardless of their biological or synthetic origins. Furthermore, it opens up new dimensions in the development of empathetic AI, potentially leading to machines that can understand and relate to human emotions more deeply than ever before.

As we stand at the cusp of this technological frontier, the notion of conscious AI invites us to rethink the essence of awareness and intelligence. It challenges us to expand our empathy not just to other humans or animals but to the artificial minds we are creating. As AI continues to evolve, the exploration of its potential consciousness will undoubtedly be one of the most intriguing and contentious debates of our time.[7]

Rogue planets, celestial bodies adrift in the galaxy unbound by any star, may harbor the secret to an entirely new category of life. Far from the warmth of a sun, these wanderers of the cosmos challenge the conventional criteria for life-supporting environments. Yet scientists speculate that beneath their icy exteriors, the atmospheres of rogue planets could act as galactic greenhouses, trapping heat and potentially creating habitable conditions for forms of life unknown to us.

This theory opens up thrilling possibilities for the search for extraterrestrial life, suggesting that life could thrive in the most unexpected placesdeep within the atmospheres of planets untethered from any solar system. Here, protected from the harshness of space, life could develop under the glow of a thick atmosphere that traps internal heat, possibly from radioactive decay or residual formation heat. These hidden oases could be home to ecosystems that defy our Earth-centric understanding of life, operating under principles and processes alien to those we know.

The prospect of discovering life in the rogue planets atmospheres invites us to expand our definition of habitable zones and consider the resilience and adaptability of life. As we develop the technology to probe these distant wanderers, we edge closer to uncovering the mysteries of lifes potential to flourish in the galaxys farthest reaches, challenging our assumptions about where and how life can exist.[8]

The notion of Neurogenesis after Death delves into the mysterious and controversial possibility that human brain activity could, under certain conditions, restart or continue after clinical death. This concept challenges our fundamental understanding of life and death, suggesting that the end might not be as absolute as we currently believe.

Recent studies have indicated that certain genes involved in the process of forming new neural connections can become active hours or even days after the biological markers of death have been identified. This hints at a form of post-mortem consciousness or a previously unrecognized capacity for the brain to attempt self-repair.

The implications of such findings are profound, blurring the lines between life and death and forcing a reevaluation of what it means to be truly dead. If the brain can initiate processes associated with healing or growth after the heart has stopped, it could have significant ramifications for medical science, ethics, and the legal definition of death. This research also raises fascinating questions about the nature of consciousness and whether any form of awareness could persist or reemerge during these post-mortem biological activities.

Exploring the enigma of neurogenesis after death invites us into a realm where science fiction intersects with medical research, challenging our perceptions and opening up new frontiers in our quest to understand the mysteries of life and the afterlife. As we continue to explore these phenomena, we may find that death, much like life, is far more complex and nuanced than we ever imagined.[9]

In 1969, Leonard Susskind introduced a visionary concept that would redefine our understanding of the cosmoss fundamental nature. He proposed that the universes most elementary particles are not point-like dots but rather tiny, vibrating loops of energy. This profound insight laid the groundwork for string theory. This framework paints the cosmos not as a static collection of particles but as a dynamic orchestra of vibrating strings. Each strings vibration pattern determines the particles properties, suggesting that every force and matter piece emanates from these minuscule strings harmonics.

String theory offers a unified perspective of the universe, bridging gaps between conflicting theories and promising a coherent theory of quantum gravity. It suggests that the universes fabric is a complex tapestry of intertwined energy strings whose vibrations give rise to the particles and forces that compose our reality. This paradigm shift from particles to strings invites us to imagine a cosmos where the laws of physics are the harmonies of a cosmic symphony, with strings vibrating in multiple dimensions beyond our sensory perception.

Exploring the universe through the lens of string theory not only challenges our conventional notions of space and time but also opens the door to discovering the universes hidden dimensions. As we delve deeper into the mysteries of string theory, we embark on a journey to uncover the universes ultimate symphony, seeking the melodies that underpin the cosmoss very essence. This pursuit not only enriches our understanding of the universes beginning but also heralds a new era of cosmic exploration, where the smallest strings could hold the keys to the grandest mysteries.[10]
