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: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
