Research casts doubt on controversial scientific theory

07.05.2003


Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into calcium.



Biological cold fusion, also known as the ‘Kervran effect’, is the principle that living organisms can act as alchemists and turn one element into another. The French Scientist, Louis C. Kervran claimed that he had proven the existence of cold fusion by feeding hens with a calcium deficient diet and observing that they still laid eggs with the usual calcium rich shells. He argued that they did this by changing silicon into calcium.

In a paper published in the Spring 2003 edition of The Journal of Scientific Exploration, Dr. Milton Wainwright, of the Molecular Biology and Biotechnology Department at the University of Sheffield casts serious doubts on one of the alleged proofs of the Kervran Effect . He describes how he and his team used the common mould, Aspergillus niger, to attempt to turn manganese into iron. This was another example cited in Kervran’s work.


The team subjected the fungus and the metal to a variety of different conditions and monitored it using highly sensitive equipment, but were unable to show that such a change occurs.

Dr Wainwright says, “It is important that controversial areas of science are subjected to rigorous scrutiny. It’s difficult for science to categorically prove that something doesn’t happen, but our work, coupled with the fact that biological cold fusion appears to be theoretically impossible, suggests that the phenomenon is non-existent.”

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
