What is it that made them almost fanatical about building pyramids? Is it the geometric perfection of the structure? Or did they consider it a stairway

3D Virus Image Taken At Highest Resolution Ever

Viruses are sub-microscopic infectious agents that need other cells in order to reproduce. In fact, some scientists claim that viruses are not living beings, as they do not meet the criteria of the definition of life, because they don’t have cells; but they do have genes and evolve by natural selection. Still, they can be very harmful to us, so

Why most people fear snakes

    Most people fear snakes, this kind of phobia being one of the most common in the world, although many people have never actually seen a snake. So how can this be?

Science ABC: X-rays

                                                                                                   (no science in this picture, it’s just fun) What are X-rays? You may think you know the answer, but things are a bit more complicated than they seem. In fact, they are a form of electromagnetic radiation, similar to microwaves or radio waves. But X-rays have way more energy than these types of radiation, which makes them special.They are

Understanding the Stem Cells

  There is a lot of interest around the problem of stem cells; a lot of practical discussions, and a lot of moral discussions as well. Whether it is good or it is not good to use them or whether it is religiously condemned is not going to be discussed here. This is meant to make you understand how stem

What Is Genetic Engineering

  So according to Wikipedia, genetic engineering involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein to reach desired effects. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, enhancing existing ones, or producing a
