Science ABC: understanding thunder and lightning

In ancient times, people looked up to the sky and thought it was the home of the gods; they found divine explanation for pretty much all natural phenomenae, and thunder was usually a tool of the gods. Strange enough, but today things aren’t really that different. Sure, you’ll say, we know it’s a discharge of electricity and not the hammer

Science ABC: The Horizon Problem

Today’s topic is a bit more complex, but requires only elementary notions to understand. It’s a problems that scientists have had many problems with, to say the least. The truth is despite the fact that there are some solutions that would partially (or even totally) explain the issue, there is no satisfactory explanation to this Big Bang related topic. Basically,

Science ABC: understanding algae based biofuels

Due to the need for a constant development in alternative sources of energy and development, scientists have been turning their attention towards algae, which could prove the good answer to many questions raised by the current necesities. Algae are a very large and diverified group of photosynthetic organisms, crucial to marine life and numerous ecosystems. You’ve probably heard about algae

Robofish work together

Kristi Morgansen, an aeronautics and astronautics engineer at the University of Washington presented the results of these amazing robofish. These new robots that feature tails and fins passed the test with flying colours.What makes it so amazing? Well, unlike most robots which receive instructions from a scientist or satellite, Robofish (as they are called) rely solely on each other and

Science ABC: What Rainbows are and How They Form

Photo by wikipedia What are Rainbows? Rainbows are some of the most spectacular phenomena in nature; they’ve fascinated and stimulated the imagination of people since the dawn of mankind, and continue to do so to this day. There are all sorts of legends that suround them, from the treasure at the end of the rainbow to the house of gods for

Science ABC – how aztecs did the math

The Aztecs were the dominant civilization in Mexico for several hundred years, when their “reign” was stopped by the Spanish in the early 1500s. An astonishing thing about them (among others) is the fact that they left behind really extensive mathematical writings, intriguing scholars ’til this day. Two manuscripts in particular have been object to study because they portray land

Science ABC – how were the pyramids built?

I’ve always been fascinated by pyramids; the Egyptians, the Aztecs, Mayans were three very different cultures and civilizations, from different parts of the world but they were all fascinated by this tipe of ‘building’. 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? Well a recent study shows that throughout evolutionary time, mankind has learned to fear and avoid snakes (as well as spiders for that matter). Psychologists found that

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
