What if quantum physics could eradicate illness? | Jim Al-Khalili for Big Think

TL;DR

Quantum biology explores quantum phenomena within living cells, which may have significant implications for evolution and health.

Transcript

• Quantum biology is looking for and studying quantum phenomena, quantum effects inside living cells. On the one hand, physicists don't like applying their laws of physics and quantum mechanics inside living systems because biology's hard, it's complicated, it's messy. It's hard enough trying to find quantum effects in a sterile physics lab. How d... Read More

Key Insights

• 👮 Physicists find it challenging to apply their laws and theories to the complex and messy environment of living systems.
• 🖤 Biologists, for the most part, lack the mathematical understanding of quantum mechanics and have made considerable progress in molecular biology without it.
• 🖐️ Chemists argue that quantum effects are expected at the molecular level and may occur in biological processes, but they may not play a functional role.
• 😵 Certain biochemical processes, such as DNA mutations, may be influenced by quantum tunneling, where particles can cross energy barriers.
• 🦾 Understanding the role of quantum mechanics in biology could help inhibit certain mutations and have significant implications for our health.
• 🛟 Quantum biology may have a fundamental role in the entire evolution of life on Earth.
• 🤗 Progress in genetics and gene editing opens up possibilities for manipulating life at a molecular scale, potentially leveraging quantum tunneling for beneficial outcomes.

Questions & Answers

Q: Why do physicists and biologists have different perspectives on the study of quantum biology?

Physicists find biology complex and messy, making it challenging to apply their laws and theories in living systems. On the other hand, biologists lack the mathematical understanding of quantum mechanics to fully embrace its potential in their field.

Q: What is the role of chemists in the debate regarding quantum biology?

Chemists argue that at the molecular level, quantum effects are expected, and it's not surprising that they may occur in biological processes. They caution against creating new scientific fields unnecessarily.

Q: How might quantum tunneling play a role in DNA mutations?

Quantum tunneling allows particles to cross energy barriers, potentially enabling a hydrogen atom to jump from one DNA strand to another, leading to mutations. While energy from surrounding molecules can facilitate this jump, quantum tunneling provides an alternative mechanism.

Q: What implications could quantum mechanics in biology have for our health?

If quantum tunneling plays an important role in mutations, it might be possible to inhibit certain mutations by blocking the ability of particles to quantum tunnel. This understanding could have significant implications for our health and influence the evolution of life on Earth.

Summary & Key Takeaways

• Physicists and biologists disagree on the role of quantum mechanics in living systems, with physicists finding it too complicated and biologists lacking understanding in quantum mechanics.

• Chemists argue that at the molecular level, quantum effects are expected, but they may not play a functional role in biological processes.

• However, there is a possibility that quantum effects, such as quantum tunneling, could have a fundamental role in certain biochemical processes, including DNA mutations.

• Understanding the influence of quantum mechanics in biology could have implications for inhibiting mutations and improving our health outcomes.
