A theory, like the theory of evolution, is more than a guess: it's grounded in fact. A hypothesis is an assumption constructed for the sake of testing
but rather hundreds of scholars who contributed to something that we now call the “Cell Theory”. Basically, this explained to the world what we, as living organisms, are made of. This theory was followed by many more revelations about the complexity of life on Earth that changed the entire...
Introduction to cell theory The cell theory, which recognised cells being the structural and functional unit of all living beings, was put forward by Schleiden and Schwann in 1838 and 1839 respectively. Later in 1855, Rudolf Virchow explained that all cells arise from pre-existing cells. ...
(1) The mechanism of uranium→hydrogen decay chain, as opposed to the prevailing theory of radioactive decay which holds that uranium-238 decays only to stable lead-206, while all other elements lighter than lead-206 (except for 43-technetium) are stable and they are not thought to decay a...
The tumor microenvironment (TME) is comprised of non-malignant cells that interact with each other and with cancer cells, critically impacting cancer biology. The TME is complex, and understanding it requires simplifying approaches. Here we provide an experimental-mathematical approach to decompose the...
The chilling theory depicted in the Netflix series ‘3 Body Problem’ is just one explanation for our lack of encounters with extraterrestrial intelligence.
Molecular docking is a computational technique that predicts the binding affinity of ligands to receptor proteins. Although it has potential uses in nutraceutical research, it has developed into a formidable tool for drug development. Bioactive substance
The theory of star-planet coevolution however holds that the sun itself cannot independently generate energy, nor can it independently synthesize elements. On the contrary, the sun-core-operated physical mechanism of energy generation and element synthesis is essentially a sun-planet co-created and ...
The bend entrance acts as the point of disturbance to the flow, and the immediate downstream flow undulates across the channel and along the bend and follows the classical theory of cross-wave characteristics in supercritical flows19,20,25, as shown in Fig. 1. According to both the ...
