Impediments to advancement of our understanding of the world within which we reside

It t so much what we don’t know that compromises science and its advancement, but what we know that isn’t so. Preconceived notions are often so ingrained in a field that they are never tested, or even considered appropriate to test. Often interdisciplinary efforts result in an interloper (scientists trained in a different field) naively questioning what the primary discipline has always believed. The interloper’s testing of that hypothesis often reveals “inconvenient truths.”

Impediments to advancement The “collective consciousness” of some fields is a major impediment even to publication of disparate evidence, let alone that which disproves pet theories. The term behavioral science could be used to describe the response of a field to new information, analogous to application of the term behavioral economics to describe response to assaults on the “imaginary world” in which some thrive.

Pathological Investigations on Galilee Tilapia (Sarotherodon galilaeus) Following Chronic Exposure to Cadmium Chloride



Freshwater acquires contaminated with a large number of pollutants and it has become a matter of major concern allover the world. Among pollutants and metals are of particular interest because of their varied effects and the range of concentrations which may cause toxic effects to fish. Many studies are available that demonstrate heavy metal toxicity in fish. Cadmium has no biological function in living organisms. It widely used in fertilizer, automotive, dye, plastics and synthetic fiber industries and battery production. 

Sarotherodon galilaeusEven small amounts of this metal entered into aquatic systems, results in accumulation in various tissues, changes in metabolic, physiologic and biochemical parameters and death in sensitive species. Cadmiumexposure may lead to the results of some pathophysiological damages in varioustissues including liver, brain and kidney.One of the common and commercially important cultured tilapia species is Sarotherodon galilaeus (S. galilaeus) but Limited information is available about the morphopathological alterations of chronic cadmium toxicity in this fish.
