Viruses and human skin named as new test beds for quantum biology in $53,000 essay competition

Quantum biology - the study of quantum mechanical processes in living systems - has grown from a fringe hypothesis into a legitimate research area over the past two decades. Evidence for quantum effects in photosynthesis, enzyme catalysis, bird navigation, and possibly DNA mutation has accumulated to the point where the question is no longer whether quantum mechanics matters in biology, but where, and how much.

The Foundational Questions Institute (FQxI) posed a sharper version of that question in its 13th essay competition: "How Quantum is Life?" The $53,000 competition, presented in partnership with the Paradox Science Institute, drew 97 eligible entries from academics, medical professionals, students, and non-scientists across six continents. Eight winners were announced on February 14, 2026.

Two essays split the $15,000 first prize, sharing a total of $30,000. Each independently identified a biological system that the field has largely neglected as a test bed for quantum effects - and made the case for why that neglect should end.

Viruses as quantum probes

Connor Thompson, a PhD student in microbiology and immunology at the University of British Columbia, argued that viruses occupy a unique position for quantum biology: they exist at the conceptual boundary between living and non-living matter. Viruses lack metabolism and do not reproduce independently, yet they encode genetic information, evolve, and direct complex molecular processes inside host cells.

That boundary position makes them, Thompson argued, ideal probes for testing where quantum effects matter in biological processes. Viral capsid assembly, nucleic acid packaging, and the precise molecular recognition events required for host cell entry are all processes that might involve quantum mechanical contributions - and viruses offer experimental accessibility that complex cellular systems do not. The essay title: "Viruses: Quantum Probes of Life."

Skin as a quantum interface

Samuel Morriss, a physician based in Melbourne, Australia, approached the problem from medicine rather than molecular biology. His essay, "How Quantum is the Skin? A Clinician's Perspective on Life at the Nanoscale," argued that the skin is a living interface between physics and biology that has been overlooked in quantum biology discussions despite its direct relevance to medicine.

Skin mediates light absorption (with direct quantum photochemical consequences for vitamin D synthesis, DNA damage, and sensory signaling), temperature regulation, mechanical sensing, and chemical barrier function. All of these involve nanoscale molecular processes where quantum effects could plausibly operate. As a tissue that researchers can access, measure, and perturb non-invasively, it offers experimental advantages over internal organs.

"'How quantum is life?' is no longer merely a philosophical question as it has practical and profound implications for medicine," Morriss wrote. "When biology and medicine lost contact with physics, understanding stalled. It is time to re-establish that connection."

The other prize winners

The second prize of $7,500 went to Gerard McCaul for "Spanspermia: Does Life Come from Outer Hilbert Space?" - an essay connecting quantum mechanics to questions about the origins of life. Michael Montague won the $5,000 third prize for "Scale Shifting: Quantum Biology, Quantum Omics, and a Quantum Biotech Future."

A Special Undergraduate Prize of $3,000 went to Gabriela Frajtag, an undergraduate student at Ilum School of Science (CNPEM) in Brazil, for an essay on the history and future of quantum biology. The judges noted being particularly impressed by the quality of an undergraduate submission. Three Special Mention prizes of $2,500 each went to Rishab Ghosh, Aswathy Prakash, and Ian Reppel.

The competition was judged blindly, with entrant identities concealed throughout the evaluation process - the second FQxI competition to use this approach.

What these essays do not resolve

Essay competitions of this kind function differently from experimental research. The winning arguments are intellectually compelling proposals - they identify systems worth studying and make cases for why quantum effects might matter there. They do not provide empirical data demonstrating that quantum effects actually operate in viruses or skin at biologically meaningful scales. That work, if it is to happen, requires laboratory investigation that the essays propose but cannot substitute for.

Quantum biology remains a field where the distance between theoretical plausibility and experimental confirmation is often substantial. The same quantum effects that are clearly documented in photosynthetic complexes or enzyme active sites under controlled conditions may or may not persist at physiological temperatures and in the noisy molecular environments of intact tissues. The competition's value lies in directing attention toward underexplored systems - not in establishing that those systems are definitively quantum.
