Introduction The eugenics movement, which gained prominence in the late 19th and early 20th centuries, sought to improve the genetic quality of human populations through selective breeding. This movement was underpinned by various scientific, social, and political prerequisites that facilitated its rise and acceptance in different societies. The term "eugenics," coined by Francis Galton, reflects the application of Darwinian evolutionary...

'Can I get two tickets to Mars?' This might sound ridiculous right now, but it might be our reality in the near future. Whether humans should or should not colonize Mars is a big debate, and we should care about it because we all live on this Earth, and colonizing Mars would be a big step for all of mankind,...

ABSTRACT The effect of salt stress under the two salinity levels and control (0, 100mM, 150mM) on three varieties of wheat SASSUI, SEHAR, MARVI was conducted. The data showed that the NaCl salinity stress significantly affected the growth of wheat seed arrtibutes by reducing the shoot and root length. Regarding the germination, the maximum germination was found in genotype SASSUI...

Introduction Language is the most primeval of persuasion devices. Through an indirect manipulation of language, proficient speakers have authentically been able to influence the perceptions, thoughts, purposes and agitation of the public, to the extent of causing people to accept false statements as true proclamations or even to support policies contradictory with their interests. Leaders have to plan, organize, lead...

“All substances are poisons; it is the dose that makes the poison.”, Philippus Aureolus Theophrastus Bombastus von Hohenheim stated. Heavy metals are commonly characterized as metals with a high toxicity level in high concentrations generally with high atomic numbers, atomic masses, or densities, and those metals are located on the 3rd-15th groups and through the 4th-6th periods. Moreover, heavy metals...

We should be looking at the possibility of other life existence on Earth. Could there really only be humans on the Earth? There is a high chance that there is another life existence like aliens shown through studies, places, and events.. A reason to think about aliens existing is due to the amount of alleged sightings. In June 1947, an...

Introduction In recent years, the integration of machine learning algorithms into agricultural practices has revolutionized the way plant diseases are detected and managed. As global food demand increases, ensuring crop health becomes paramount for sustaining food supply chains. Traditional methods of plant disease detection, which often rely on human expertise, are labor-intensive, time-consuming, and prone to errors. Machine learning, with...

Introduction Food adulteration can be defined as adding removing or replacing any substance which will eventually exaggerate the natural quality of any food product. Producing food with high quality and safety should be the main focus of food industry. But as in for today food manufacturers are more tend to manufacture food with adulterants (Mi et al., 2015). These food...

Inquiry-based learning (IBL) is a student-centered Pedagogic strategy, a process that is ideally led by students. This strategy aims to teach students science by doing it, to attain conceptual change, or accommodate new knowledge, as Jean Piaget's theory of cognitive development claims. To achieve that, students work collaboratively. Build on previous knowledge and one another’s work engaging in active self-directed...

Introduction Humans have tens of thousands of genes, and the development of DNA microarrays by Patrick O. Brown, Joseph DeRisi, David Botstein, and colleagues in the mid-1990s made it possible to examine the expression of thousands of genes at once. Initial experiments using microarrays focused on determining which genes were expressed differently between normal cells and cancerous cells. Over time,...

There are thousands and thousands of explanations on how the universe was created or formed; the most popular one being – The Big Bang Theory. Although there are thousands of explanations, I will only be going over three. The three theories are: 1.) The Big Bang Theory, 2.) The Steady State Theory, and 3.) Creationism. First I explain these three...

Introduction Steel often interacts with hydrogen in a variety of ways, especially because steel is used typically in structural components. Today these applications may vary from bridges to the transportation of natural gas, making the knowledge of this interaction useful [1]. Due to its high chemical reactivity, hydrogen can diffuse into the surface of steel and then appear ionically or...
