Hi Keiths,

Someone who believes that life depends on superconduction, and that there is a conspiracy to suppress information about superconductivity, is neither knowledgeable nor sane.

Joy is quite capable to defending herself.  MikeGene's rabbit threads are available to open discussions.  If someone wants to ask her something, there is a recent rabbit thread available that anyone can use. Meanwhile, I thank you for the opportunity for me to point out the use of quantum mechanics in life.

It appears photosynthesis involves quantum superposition to achieve super conductivity.

This is from Berkley Lab's Research News.  The article is titled Quantum Secrets of Photosynthesis Revealed.

BERKELEY, CA —Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key – the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved.
Electronic spectroscopy measurements made on a femtosecond (millionths of a billionth of a second) time-scale showed these oscillations meeting and interfering constructively, forming wavelike motions of energy (superposition states) that can explore all potential energy pathways simultaneously and reversibly, meaning they can retreat from wrong pathways with no penalty. This finding contradicts the classical description of the photosynthetic energy transfer process as one in which excitation energy hops from light-capturing pigment molecules to reaction center molecules step-by-step down the molecular energy ladder.

“The classical hopping description of the energy transfer process is both inadequate and inaccurate,” said Fleming. “It gives the wrong picture of how the process actually works, and misses a crucial aspect of the reason for the wonderful efficiency.”


And, of course, there is the Orch OR model of consciousness put forward by Sir Rodger Penrose and Dr. Hameroff....

In this paper we propose that aspects of quantum theory (e.g. quantum coherence) and of a newly proposed physical phenomenon of quantum wave function "self-collapse"(objective reduction: OR -Penrose, 1994) are essential for consciousness, and occur in cytoskeletal microtubules and other structures within each of the brain's neurons. The particular characteristics of microtubules suitable for quantum effects include their crystal-like lattice structure, hollow inner core, organization of cell function and capacity for information processing. We envisage that conformational states of microtubule subunits (tubulins) are coupled to internal quantum events, and cooperatively interact (compute) with other tubulins. We further assume that macroscopic coherent superposition of quantum-coupled tubulin conformational states occurs throughout significant brain volumes and provides the global binding essential to consciousness.

from the peer reviewed paper  Orchestrated Objective Reduction of Quantum Coherence in Brain Microtubules: The "Orch OR" Model for Consciousness

DNA strands are used to build artificial quantum computers.

IMO, the question gets turned around.  What makes you think life ISN'T dependent on quantum superposition and superconductivity?
