Briefings

A Howard University-led review titled Quantum Biology 2.0 examines quantum effects in protein networks, suggesting they influence biological energy processing and sensing. Key findings include collective light emission (superradiance) observed in microtubules at room temperature and evidence linking protein vibrations to quantum tunneling in enzymes. The review analyzes nearly 600 references from the past decade, organizing research into eight topics. No new datasets were generated by the authors, and the study focuses on existing literature rather than new experimental data.

Key points

• Collective light emission (superradiance) was observed in microtubules suspended in solution at room temperature, demonstrating that ordered protein arrangements can emit light more rapidly than independent molecules.
• Quantum tunneling in enzymes is supported by evidence that protein structures around reaction sites facilitate hydrogen movement during chemical bond breaking and formation.

Context

This review, published in Protein Science, expands the scope of quantum biology beyond photosynthesis and magnetic navigation to include cellular structures like microtubules and enzyme mechanisms. It aims to bridge laboratory findings with biological functions, potentially advancing quantum sensing technologies.

Limitations

The review analyzes existing literature rather than generating new datasets. Specific experimental details for the 2024 microtubule study are limited to the reported room-temperature superradiance observation, and the review does not provide causal claims about biological performance beyond what the cited studies support.
