Researchers at the University of Gothenburg, Sweden, have managed, with the help of an advanced X-ray flash, to photograph the movement of atoms during photosynthesis - an achievement that has been recognised by the journal Science.

The European Synchrotron Radiation Facility in Grenoble is home to one of the world's most advanced particle accelerators, whose pulsing X-ray beams are used by researchers to photograph and study life's tiniest components: atoms, molecules and proteins.

Using the special X-ray camera, researchers can depict the position of atoms in a molecule and obtain a three-dimensional image of something that is smaller than a billionth of a metre. Researchers at the Department of Chemistry at the University of Gothenburg and at Chalmers University of Technology have now used this advanced technology to photograph the dynamics of life's most fundamental system: photosynthesis.

The focus of the study was a protein which is central to the conversion of light to during photosynthesis, and which process the Gothenburg researchers have been the first to (successfully photograph) (capture?). The X-ray image shows how the protein temporarily stores the immediately before a chemical bond forms - a movement that takes place on a scale of less than a nanometre.

The photograph is not only a fascinating snapshot of the very core of life, but could also be used in the of the future, where researchers hope to be able to imitate the sophisticated of .

The photography is highlighted in an article in the next issue of Science.

An imponderable state beyond Photosynthesis is Piezophotonics -a dynamic-mechanism of Photons & Positrons at Work within an atomic-world as a quantum-myriad configured by the exquisite Permutation & Combination of TITHONS. May be scientific savants call it as a Light Harvesting Dyanamics… untangling the Quantum-entanglements.

TITHONs -which are the building constituents of Quantum Beingness, design and dominate the Orderliness of the Cellular-world within Genomic-domain unto enzymes, peptides & all of amino acids, propagating their catering of 'Cosmic Efficacy & Tithonicity' for building inherent, intrinsic & innate, quantitative & qualitative quark-gluon plasma ‘astral-fluid’ for a particular Being.

This encouraging pathway is a new-physics “Para-Physics” in nascency, which is indeed a distinct presents of ASTRAL SCIENCE postulated by a theory called "Cosmic Efficacy & Tithonicity" …and the same is an ELIXIR to Humankind
