Also, modern means of transportation and communication. If there is no electricity in our world, what about factories? large machines? essential items like food, cloth, paper, and many other things that are produced based on electricity? Actually, electricity is one of the most important blessings that science has given to mankind. It has also become a part of modern life and one cannot think of a world without it. The discovery of electricity changed lives drastically, starting from domestic use to industrial activities. It is one of the most important innovations of all time. In your house, electricity is important for operating all appliances, entertainment, lighting and of course, all technology. When it comes to travelling, electricity is important for the use of electric trains, airplanes and even some cars. If you think about facilities such as schools, medical facilities such as hospitals, and retail facilities, all need electricity to run efficiently. When it comes to the medical field, electricity allows for the availability of X-Rays, ECG’s and instant results regarding blood …

4 Technologies That Can Make Science Learning Easier and Funny
Last Updated on June 19, 2022 by Mostafa Science learning or science education is the teaching of science to non-scientists, such as school children, college students, and also adults within the general public. The science learning field can include work in science content, science process (the scientific method), social and citizen science, and some teaching pedagogy. In the last decades, science learning was based on traditional teaching methods. But through the last few years, we have noticed a significant change due to the revolution of the “information age.” Now we can see various applications for the internet and electronic devices in the world of science learning and teaching. Advances in computer and network technologies may facilitate and provide constructivist and cooperative learning environments, thus paving the way for cooperative activities and constructivist learning. Now let’s take a look at the main emergent technologies that are applied in science learning. Here you can find four effective technologies that have a breakthrough in science learning. Virtual labs, Simulations, and Dynamic Visualizations Unlike computational thinking, the amount of research about using virtual labs and simulation in science learning is large.

Modern Physics: Its History, Theories, And The Practical Experience of Its Virtual Labs
Last Updated on August 25, 2022 by Mostafa Introduction The emergence and development of modern physics was a giant leap in the history of mankind. This is because the main theories of modern physics reshaped our perception of the universe and caused an incredible scientific revolution. Modern physics is a branch of physics that includes the post-Newtonian concepts in the world of physics. It is based on the two major breakthroughs of the twentieth century: relativity and quantum theory. The term modern physics means up-to-date physics. This term refers to the breakthrough that happened after Newton’s laws, Maxwell’s equations, and thermodynamics, these laws which are known as “classical” physics. So modern physics can be considered the most recent step in the history of physics. This history has roots back to ancient Greece, old India, old china, the Islamic world, and medieval Europe. Then came the scientific revolution which is based on the ideas of Nicolaus Copernicus, Galileo Galilei, René Descartes, Isaac Newton, and others. In this article, we are going to take a look at the history of physics in these ages and the evolution of the main theories of modern physics. Also, we will discuss some of the …

DNA Extraction Virtual Lab Experiment from PraxiLabs
Last Updated on August 25, 2022 by Mostafa The DNA extraction virtual lab is the most affordable method to simulate an equipped laboratory that offers a realistic lab experience for the DNA extraction process. DNA extraction virtual lab helps universities to provide their students with an immersive learning experience using the technology of virtual labs to improve the quality of science education. But why do universities need to improve the quality of science education? Actually, the world is growing incredibly fast, which increases the list of growing challenges that will need to be solved by the current and future students. This is because those students will be the scientists of the future who will deal with the world’s great challenges including, but not limited to, global warming, solving starvation and water shortages, and of course curing diseases. Curing diseases need biological experts with a great passion for science and enthusiastic about studying dangerous submicroscopic infectious agents such as viruses and bacteria. And they must be brilliant in conducting biological lab experiments such as DNA extraction. This is because DNA extraction is one of the essential experiments that must be done to define, classify, and study the infection agents. So …

The Concept, Processes, and Applications of Western Blotting
Last Updated on September 22, 2022 by Sara Assem Western blot is an indispensable mechanism in the modern biomedical research laboratory, as well as in laboratories doing research in other areas. This technique is routinely used now for research purposes, for instance, clinical medical laboratories. Western blot can be used to identify a specific protein in a sample. Also, it provides information about protein size and relative abundance in the sample. Western blot is sometimes called “protein immunoblot” or “western blotting.” It is considered as an analytical technique used mainly in molecular biology and immunogenetics where antibodies are used to specifically detect their antigen. The term “blotting” refers to the transfer of biological samples from a gel to a membrane and their subsequent detection on the surface of the membrane. The development of the protein blotting techniques is credited to “Harry Towbin.” In 1978 “Harry Towbin” was hired by “Julian Gordon” at the “Friedrich-Miescher-Institute” in Basel for a postdoctoral fellowship. “Harry” and “Julian” worked in cooperation with “Theo Staehelin,” a pioneer in the field of initiation factors for mammalian protein synthesis who had ample expertise in ribosomes. In 1979 they published a paper entitled “Electrophoretic Transfer of Proteins From …

PCR Analysis: COVID-19 Infection Detection Method… PraxiLabs Initiative Experiments
Last Updated on June 20, 2022 by Mostafa Recently, with the emergence of COVID-19 virus, we often hear the term “PCR analysis.” Polymerase Chain Reaction “PCR” is the basic analysis currently used to detect Infected people with COVID-19. Through the Polymerase Chain Reaction (PCR analysis), scientists can detect the presence of viruses that cause infection, even when they are present in small quantities in the body. This method contributes to the diagnosis of transmissible viral diseases, as well as to the identification of mutations in various genetic disorders. PraxiLabs 3D virtual biology laboratory provides the PCR experiment within its initiative to support practical colleges, where you can conduct the experiment in the virtual biology lab, which provides science students and professors with a more accurate understanding of PCR meaning. These experiments are completely free for a whole month for practical college professors and students. You can create your PraxiLabs account to conduct these experiments from here. What is Polymerase Chain Reaction (PCR)? Polymerase Chain Reaction is one of the important techniques used to amplify a portion of the DNA chain using very small amounts of materials, where the DNA chain can be multiplied more than a million times.
