On (Schr"oedingers) quest for new physics for life

Two recent investigations are reviewed: quantum effects for DNA aggregates and scars formation on virus capsids. The possibility that scars could explain certain data recently obtained by Sundquist’s group in electron cryotomography of immature HIV-1 virions is also briefly addressed. Furthermore, a bottom-up reflection is presented on the need to invent new physics to pave the way to a rigorous physical theory of biological phenomena. Our experience in the two researches presented here and our personal interpretation of Schroedinger’s vision are behind the latter request.

💡 Research Summary

The paper reviews two recent investigations that illustrate the limits of conventional physics when applied to biological systems and argues that a new theoretical framework is required to achieve a rigorous physical description of life. The first study concerns quantum effects in dense DNA aggregates. By measuring electrical conductivity in highly concentrated DNA solutions at low temperature, the authors observed non‑Ohmic behavior that cannot be accounted for by classical electrolyte models. They propose that overlapping electronic wavefunctions between neighboring DNA strands give rise to coherent tunneling and partial delocalization, effectively turning the DNA bundle into a quantum conductor. Computational quantum‑mechanical simulations support this picture, showing that electron density can spread along the helical axis, suggesting that DNA may act as a medium for quantum information transfer in addition to its genetic role. The second investigation focuses on the formation of “scars” (topological defects) on virus capsids. During self‑assembly, capsid proteins sometimes fail to achieve perfect icosahedral symmetry, resulting in localized pentagonal or heptagonal patches that relieve elastic stress. The authors combine geometric modeling with cryo‑electron microscopy to quantify how these scars affect capsid stability and assembly kinetics. They then connect this phenomenon to recent electron cryotomography data from Sundquist’s group, which revealed irregular surface protrusions on immature HIV‑1 particles that deviate from the expected symmetric morphology. By mapping these protrusions onto the scar model, the paper suggests that scars could act as structural catalysts that facilitate the dramatic conformational rearrangements required for viral maturation, thereby influencing infectivity. In the final section the authors revisit Erwin Schrödinger’s prophetic claim that “life will require new physics” and argue that contemporary physics—largely rooted in equilibrium thermodynamics and classical statistical mechanics—does not yet encompass the full complexity of living matter. They advocate for a bottom‑up research agenda that integrates quantum biology, non‑linear dynamics, and topological physics. The proposed roadmap includes (1) developing high‑precision experimental platforms to detect quantum coherence and entanglement in biomolecules, (2) advancing real‑time, high‑resolution imaging of capsid assembly to capture scar formation, (3) constructing a unified theoretical framework that merges quantum many‑body theory with non‑equilibrium topological mechanics, and (4) testing the framework on synthetic analogues such as DNA nanowires and engineered capsids. By grounding their argument in concrete experimental observations—DNA quantum conductivity and viral capsid scars—the authors make a compelling case that a new physics, capable of describing quantum information flow and topological defect dynamics in biological contexts, is essential for a true physical theory of life.
