A future with quantum biology - with Alexandra Olaya-Castro
Ғылым және технология
Scientific and technological advances have enabled us to zoom into the biological world. We can get down to the biomolecular scale, a domain where quantum phenomena can take place and therefore cannot be neglected.

This talk was recorded at the Royal Institution on 28 October 2022.
Upon completing her doctoral studies in 2005 at the University of Oxford, Alexandra Olaya-Castro was subsequently awarded a three-year Junior Research Fellowship by Trinity College (Oxford), where she began her independent research career.
In November 2008 Alexandra Olaya-Castro obtained a five-year EPSRC Career Acceleration Fellowship that allowed her to start a research group in the Department of Physics and Astronomy of University College London. She was then appointed as a Lecturer in September 2011, was promoted to Reader in October 2015 and to full Professor in 2018.
Throughout her career Alexandra has made scientific contributions to the understanding of signatures and implications of quantum coherence in a variety of quantum systems that include exciton condensates in quantum wells, multi-qubit systems embedded in optical cavities and, her current focus, photo-activated biomolecular systems.

Most interesting talk on this subject area that I have ever heard. I do hope to hear more fromAlexandra Olaya-Castro in the future!
The beauty of these components at the molecular level is amazing. The photon antenna in particular is astonishing.

Fascinating talk. Thank you very much.
Fantastic presentation
Great lecture. Can't wait for Quantam Physiology :D
Amazingly cool talk. I wouldn't be surprised at all if a chaotic critical point in the relationship between separated parts of the chemical structure facilitates energy capture and transfer.
Congratulations to you and your lab team!
Absolutely brilliant lecture!

So, photosynthesis is only possible because of quantum mechanical effects. This is mind blowing. Inanimate material on Earth 3.8 billion years ago evolved to create life incorporating quantum mechanical processes. So is it possible that consciousness is also a consequence of a quantum mechanical effect?

Explain the "co-operation" process of these Nana scale quantum entities during chemical photosynthesis. Easy to say.

How difficult is it to reproduce these results synthetically? Is it plausible that such processes can also occur elsewhere in the universe? What does this say about the origin of life? Thank you, what a great historical presentation. Immediately raises a lot of follow-up questions. Fantastic!

Wondering if the dual proprieties of light could provide additional insights? Light exhibits dual properties of wave and photon. As a wave, light exhibits properties like reflection, refraction, and interference, while as a photon, it has a discrete energy and behaves as a particle. This duality was explained by quantum mechanics. The wave-like properties of light follow the laws of Maxwell's equations, while the particle-like properties follow the principles of quantum mechanics.

I am very interested in this subject but found the talk difficult to listen to. I wish she would have spent more time explaining the items in a slide before talking about the whole slide. Also, way too much introduction. The first 25 min could be eliminated. It would have been better to start right off with an example quantum event.
Well, I can't hear this at all. Before uploading, try taking your video, and porting it to a completely different platform/device and seeing if the audio comes out correct. Yes I know often the audio does not always work perfectly, but a instructor who can not be heard clearly is passing no information on to anyone.

If I'm allowed to do nitpicking, I would like them (quantum 'big things' researchers) to specify what exactly they mean by "quantum processes". Are they processes that CAN be explained in the framework of quantum mechanics, or that CANNOT be explained in the framework of classical mechanics? I think only the latter definition is suitable for the term "quantum processes". For instance, pendulum isochronism can be explained in the framework of quantum mechanics, but nobody calls it a quantum process. As far as this video is concerned, I'm not fully convinced that the shift has something to do with the quantum in the above sense. The shift due to an additional interaction can occur in purely classical systems as well. Due to an additional interaction, of course, the energy transfer rate would naturally change. If the increment occurs only in the framework of quantum mechanics or is more significant there, that would be interesting.

The high efficiency of photosynthesis has been known for a while. Between her thick accent and aloof communication, I didn't get why these results are supposed to be a big deal. The big thing seems to be that vibronic coupling facilitates electron transfer, but even that isn't too surprising if we remember BCS superconductivity happens due to phononic coupling. I may be completely wrong in my assessment, but this looks and feels like a nothing sandwich - much like many a colloquium I attended back in uni.

QM is fundamental. And if we can control this without the use of things like The Large Hadron Collider, we could probably direct energy however we like. On a DNA-level it would mean that we could design cells to cure many diseases, and much more. Thanks for this. Maybe one of the most interesting findings now when we seem to be stuck in theories impossible to experimentally verify.

Photosynthesis also relies on CO2. The very thing some -rich- people want to reduce to zero from humans, cattle and other sources. Too little CO2 will lead to plant deaths and plant deaths lead to a reduction in oxygen, a reduction of oxygen will lead to the death of mammals and other life dependent on it. To 'fight' high CO2 levels best would be to plant more trees, not to stop us or any other forms of life from producing it.
@skitzo23
Жыл бұрын
Plants release CO2 by cellular respiration and after they die. You can't sustainably offset CO2 through planting trees while still using up fossil fuels. That is a scientific fact. Also, there will never be 'too little' CO2 just because humans stop burning former organic matter. Life (photosynthetic) on earth managed with all the CO2 available for almost 4bn years. I think it can manage without us burning fossil fuels. And even if CO2 levels got critically low (I felt dumber just typing that), what is stopping humanity to restart burning things at any point? Anthropogenic climate change is real, get over it.

You realize it's impossible to reduce to zero our co2 emissions? They want net zero which is very different from what you are implying. But yes conserving forests (especially rainforests and mosses) is definitely a good thing. But we are also producing wayy too much co2 per person
