Imagine using your cell phone to control the activity of your own cells to treat injuries
& diseases. It sounds like something from the imagination of an overly optimistic science fiction writer. But this may one day be a possibility through the emerging field of quantum biology.
Over the past few decades, scientists have made incredible progress in understanding
and manipulating biological systems at increasingly small scales, from protein folding
to genetic engineering. And yet, the extent to which quantum effects influence living systems remains barely understood.
Quantum effects are phenomena that occur between atoms and molecules that can’t be explained by classical physics. It has been known for more than a century that the rules of classical mechanics, like Newton’s laws of motion, break down at atomic scales. Instead, tiny objects behave according to a different set of laws known as quantum mechanics.
For humans, who can only perceive the macroscopic world, or what’s visible to the naked eye, quantum mechanics can seem counterintuitive and somewhat magical. Things you might not expect happen in the quantum world, like electrons “tunneling” through tiny energy barriers and appearing on the other side unscathed or being in two different places at the same time in a phenomenon called superposition.
I am trained as a quantum engineer. Research in quantum mechanics is usually geared toward technology. However, and somewhat surprisingly, there is increasing evidence that nature – an engineer with billions of years of practice — has learned how to use quantum mechanics to function optimally. If this is indeed true, it means that our understanding of biology is radically incomplete. It also means that we could possibly control physiological processes by using the quantum properties of biological matter.

Researchers can manipulate quantum phenomena to build better technology. In fact, you already live in a quantum-powered world: from laser pointers to GPS, magnetic resonance imaging, and the transistors in your computer – all these technologies rely on quantum effects.
In general, quantum effects only manifest at very small length and mass scales or when temperatures approach absolute zero. This is because quantum objects like atoms and molecules lose their “quantumness” when they uncontrollably interact with each other and their environment. In other words, a macroscopic collection of quantum objects is better described by the laws of classical mechanics. Everything that starts quantum dies classical. For example, an electron can be manipulated to be in two places at the same time, but it will end up in only one place after a short while – exactly what would be expected classically.
In a complicated, noisy biological system, it is thus expected that most quantum effects will rapidly disappear, washed out in what the physicist Erwin Schrödinger called the “warm, wet environment of the cell.” To most physicists, the fact that the living world operates at elevated temperatures and in complex environments implies that biology can be adequately and fully described by classical physics: no funky barrier crossing, no being in multiple locations simultaneously.

Chemists, however, have for a long time begged to differ. Research on basic chemical reactions at room temperature unambiguously shows that processes occurring within biomolecules like proteins and genetic material are the result of quantum effects. Importantly, such nanoscopic, short-lived quantum effects are consistent with driving some macroscopic physiological processes that biologists have measured in living cells
and organisms. Research suggests that quantum effects influence biological functions, including regulating enzyme activity, sensing magnetic fields, cell metabolism, and electron transport in biomolecules.

The tantalizing possibility that subtle quantum effects can tweak biological
processes presents both an exciting frontier and a challenge to scientists.
Studying quantum mechanical effects in biology requires tools that can measure the short time scales, small length scales, and subtle differences in quantum states that give rise to physiological changes – all integrated within a traditional wet lab environment.
In my work, I build instruments to study and control the quantum properties of small things like electrons. In the same way that electrons have mass and charge, they also have a quantum property called spin. Spin defines how the electrons interact with a magnetic field in the same way that charge defines how electrons interact with an electric field.
The quantum experiments I have been building since graduate school and now in my own lab aim to apply tailored magnetic fields to change the spins of particular electrons.
Research has demonstrated that many physiological processes are influenced by weak magnetic fields. These processes include stem cell development and maturation, cell proliferation rates, genetic material repair, and countless others. These physiological responses to magnetic fields are consistent with chemical reactions that depend on the spin of particular electrons within molecules. Applying a weak magnetic field to change electron spins can thus effectively control a chemical reaction’s final products, with important physiological consequences.
Currently, a lack of understanding of how such processes work at the nanoscale level prevents researchers from determining exactly what strength and frequency of magnetic fields cause specific chemical reactions in cells. Current cellphone, wearable, and miniaturization technologies are already sufficient to produce tailored, weak magnetic fields that change physiology, both for good and for bad. The missing piece of the puzzle is; hence, a “deterministic codebook” of how to map quantum causes to physiological outcomes.
In the future, fine-tuning nature’s quantum properties could enable researchers to develop therapeutic devices that are noninvasive, remotely controlled, and accessible with a mobile phone. Electromagnetic treatments could potentially be used to prevent and treat diseases, such as brain tumors, as well as in biomanufacturing, such as increasing lab-grown meat production.
A whole new way of doing science
Quantum biology is one of the most interdisciplinary fields to ever emerge.
How do you build community and train scientists to work in this area?
Since the pandemic, my lab at the University of California, Los Angeles, and the University of Surrey’s Quantum Biology Doctoral Training Centre have also organized Big Quantum Biology meetings to provide an informal weekly forum for researchers to meet and share their expertise in fields like mainstream quantum physics, biophysics, medicine, chemistry and biology.
Research with potentially transformative implications for biology, medicine, and the physical sciences will require working within an equally transformative model of collaboration. Working in one unified lab would allow scientists from disciplines that take very different approaches to research to conduct experiments that meet the breadth of quantum biology from the quantum to the molecular, the cellular, and the organismal.
The existence of quantum biology as a discipline implies that the traditional understanding of life processes is incomplete. Further research will lead to new insights into the age-old question of what life is, how it can be controlled, and how to learn with nature to build better quantum technologies.
Your brain is responsible for controlling most of your body’s activities.
But how is memory formed, and where is it located in the brain?
Its information processing capabilities allow you to learn,
and it is the central repository of your memories.
Although neuroscientists have identified different regions of the brain were memories
are stored, such as the hippocampus in the middle of the brain, the neocortex in the top layer of the brain, and the cerebellum at the base of the skull, they have yet to identify the specific molecular structures within those areas involved in memory and learning. Research from our team of biophysicists, physical chemists, and materials scientists suggests that memory might be located in the membranes of neurons. Neuroscientists Finally Understand An Elusive Mechanism Involved in Memory Creation
How memory works
Neurons are the fundamental working units of the brain.
They are designed to transmit information to other cells, enabling the body to function. The junction between two neurons, called a synapse, and the chemistry that takes place between synapses, in the space called the synaptic cleft, are responsible for learning and memory.
At a more fundamental level, the synapse is made of two membranes: one associated
with the presynaptic neuron that transmits information, and one associated with the postsynaptic neuron that receives information. Each membrane is made up of a lipid bilayer containing proteins and other biomolecules.
The changes taking place between these two membranes, commonly
known as synaptic plasticity, are the primary mechanism for learning and memory.
These include changes to the amounts of different proteins in the membranes,
as well as the structure of the membranes themselves.
Synaptic plasticity can be classified as short-term, lasting from milliseconds to a few minutes, or long-term, lasting from minutes to hours or longer. The chemical processes occurring between the presynaptic and postsynaptic membranes in short-term plasticity eventually lead to long-term synaptic plasticity.

Alzheimer’s Study ‘Made the Hair on My Arms Stand Up’
In one sense, the study subject’s case is grim: He began showing signs of cognitive impairment at 67, developed full-blown dementia at 72, and died two years later,
per STAT News. In another sense, his case is remarkable:
He should have developed Alzheimer’s in his early 40s because of a gene mutation
that all but guaranteed it, reports the New York Times.
However, the onset was delayed for two decades because of a second gene mutation,
one that points the way toward potential treatment, say researchers in a study at Nature Medicine. If scientists could somehow replicate what happened in the man’s brain,
they might be able to develop a drug to do the same for others.
“Reading that paper made the hair on my arms stand up,” neuroscientist Catherine Kaczorowski of the University of Michigan in Ann Arbor tells Nature.
“It’s just such an important new avenue to pursue new therapies for Alzheimer’s disease.” The Colombian man in the study belongs to a family with a genetic mutation that causes Alzheimer’s in middle age. However, his second mutation appeared to stop the disease from taking root in an area of the brain known as the entorhinal cortex, which is believed to play a crucial role in the development of Alzheimer’s, explains the Times.
The man is actually the second member of his extended family who seems to have been protected by a genetic mutation. In 2019, researchers identified a woman who similarly didn’t develop Alzheimer’s until decades later than expected.
However, she had a different genetic mutation, suggesting “there are multiple pathways that appear to stave off cognitive decline,” per STAT News. The bottom line here: “It seems that it is possible to have decades-long protection against Alzheimer’s disease,” says cell biologist Joseph Arboleda-Velasquez, one of the study authors.
