Quantum Biology

1) Quantum Life – Prof. Seth Lloyd

Seth Lloyd is Professor of Mechanical Engineering at MIT.

Prof. Lloyd is interested in information and the role it plays in physical systems, particularly systems in the quantum regime. Specific questions are: How do physical systems register information and move it about? How is information transformed and processed? And, most importantly, how do the ways in which a system transfers and transforms information determine its behavior?

He has worked on the definition of complexity using insights gained from the work of Rolf Landauer on physics of information processing and of Charles Bennett on computational measures of complexity. The definition of complexity he developed is related to the amount of thermodynamic resources required to perform a given task. Subsequently, he became a collector of measures of complexity: despite the proliferation of apparently disparate methods for quantifying the complex, he has been able to show that most such measures are closely related to each other. The definitions measure either information — the difficulty of describing a thing; or effort — the difficulty of accomplishing a task; or both.

The realization that information processing and physics are intimately related lie at the heart of Prof. Lloyd’s current work on quantum computation. Quantum computers are in essence complex quantum systems. In collaboration with Murray Gell-Mann he is working on a theory of quantum complexity. He hopes to use quantum mechanical computers to test methods by which the highly detailed, complex world that we see around us arose out of a highly symmetric, simple quantum world in the early universe.

As part of learning his current job as a professor of Mechanical Engineering at MIT, he has discovered the importance of work on complex systems for society as a whole. When the operation of a new car relies on the proper functioning of twenty microprocessors, when fear of a computer glitch inspires a global apocalyptic movement, when electronic devices from VCRs to toasters act as if they had minds of their own, it’s clear that our future welfare depends crucially on understanding how complex systems get information, and what they do with it.

1) The Nature of the Sense of Smell – Dr Luca Turin

Turin earned his Ph.D. in physiology at University College London. From 1982 until 1988, he worked in France as a researcher for the CNRS at the Villefranche Marine Station near Nice. He was then employed at the Pasteur Institute from 1988 until 1990.

After leaving the CNRS, Turin first held a visiting research position at the National Institutes of Health in North Carolina before moving back to London, where he became a lecturer in biophysics at University College London.

As of 2010, Turin is currently at MIT, working on a project to develop an electronic nose based in part on his theories, financed by DARPA. From April 2011 on, he will be working at the Fleming Biomedical Sciences Research Centre in Vari, Greece.

Turin is the author of the book The Secret of Scent (2006), which details the history and science of his theory of olfaction, and an acclaimed critical guide to perfume, Parfums: Le Guide, with two editions published in French in 1992 and 1994. He is also the subject of the 2002 book The Emperor of Scent by Chandler Burr, as well as of the 1995 BBC Horizon documentary “A Code in the Nose.”

Evolutionary Biology

Evolutionary biology is currently at the leading of science with new research and innovative insights set to profoundly impact medicine today. For an idea about how insights from evolutionary biology can impact us as nutritional therapists in practice, see this free article online called Evolutionary Medicine, it’s scope, interest and potential

Please watch the videos in the order they appear starting at number 1.

1) Inevitable Life – Dr Eric Smith

In this first video presented by BANT in a series covering Evolutionary and Quantum Biology on the BANT Blogsite, we introduce the subject from the beginning with a talk by Dr Eric Smith. Dr Eric Smith received the Bachelor of Science in Physics and Mathematics from the California Institute of Technology in 1987, and a Ph.D. in Physics from The University of Texas at Austin in 1993, with a dissertation on problems in string theory and high-temperature superconductivity. From 1993 to 2000 he worked in physical, nonlinear, and statistical acoustics at the Applied Research Labs: U. T. Austin, and at the Los Alamos National Laboratory. From 2000 he has worked at the Santa Fe Institute on problems of self-organization in thermal, chemical, and biological systems. A focus of his current work is the statistical mechanics of the transition from the geochemistry of the early earth to the first levels of biological organization, with some emphasis on the emergence of the metabolic network.

Many researchers have supposed that the emergence of life hinged on a sequence of improbable events, at the same time as they have taken for granted the ability of life on earth to persist indefinitely and to “freeze in” the consequences of early accidents. Smith argues that there is ample evidence for a different interpretation: the emergence of life was an inevitable outcome of geochemistry on the early earth, and the same forces responsible for emergence have continued to support the persistence of life ever since. Smith sets out the case that metabolism preceded control in biological evolution, and that the citric acid cycle is the key bridge from geochemistry to biology.
