Embryogenesis: Definition, Stages, and Development [MCAT]

Sonic Hedgehog Gene. CNS development and Limb development.

Learning Languages 101: Top 5 Benefits and Top 5 Tips of Learning New Languages

Humans have diversified themselves through the means of several distinct features. Take, for example, bipedalism, the use of fire, and a brain with intelligence far beyond that of any of our non-human peers. These unique abilities are distinct yet not completely unique to homo sapiens. In 1981, remains of Homo erectus and Australopithecus were discovered to have been capable to use fire after discovering charred bones from 1 to 1.5 million years ago while the non-extinct Australian Firehawk is capable of using fire to intentionally cause wildfires. Ostriches, orangutans, and even beavers are capable of if not accustomed to bipedalism. Rauisuchia, a crocodylomorph from the Triassic period, have been proven to be capable of bipedalism as well. The intelligence of dolphins and other cetaceans that have the closest known intelligence to humans. They are capable of complex actions such as feeling empathy, understand body language, and communicate in echolocation. So what really makes us unique? Many argue that the most distinctive and decisive difference between us humans and other animals is our ability to communicate in the form of languages. Today’s world has an array of languages, some with several exotic cultures. Languages allow us to express ourselves in ways that are unfathomable to any other known species in the entire universe. Join us on all the benefits of learning several languages!

Dinosaurs 101: The Shifting Image of Dinosaurs – Facts, History, and Evolution

Scientific discoveries reach the general public through schooling and news stories, though occasionally this kind of information gets filtered through the lens of pop culture. When it comes to dinosaurs, Steven Spielberg’s Jurassic Park is a prime example of this. Insights and ideas gleaned from science can inform new and creative plot elements or action set pieces, though the same is true of scientific distortions and misunderstandings. Rather than nitpicking elements of a single film, this article will briefly highlight the areas in which our understanding of dinosaurs has evolved over the past few decades.

Vaccines 101: Vaccination, Immune System, and the COVID-19 Vaccine – Benefits and Side Effects

The question of how a vaccination would work to combat the current COVID-19 pandemic is a major concern right now. Everybody has their own perspective on the situation, and in some people’s minds, vaccines do not fit into the equation. Therefore, it’s extremely important to understand what a vaccine’s purpose is, how it is supposed to achieve that purpose, how a vaccine is developed, and its benefits versus side effects before coming to a final conclusion on the subject as it relates to the pandemic. To understand a vaccination’s purpose it is necessary to first understand how a pathogen works. A pathogen is essentially any foreign material (foreign in the sense that it is not a part of the human body), that can cause disease or a malfunction of the body. They spread from surface to surface and person to person.

Microfilament and Microtubulues are made from different individual subunits. Microfilaments are made from ACTIN, while microtubules are made from TUBULIN.

Arthropods 101: Insects, Evolution, Classes, and Examples of Arthropods

Making up around 75% of all animal species in the world, arthropods are are a vast phylum of the kingdom Animalia. The name comes from the Greek words “arthro”, meaning joint, and “podos”, meaning legs. While they all share segmented bodies with joined legs, members in this phylum vary wildly, from butterflies and millipedes, to scorpions and lobsters. They are also all invertebrates, which means that they do not have backbones. Instead, they use hard exoskeletons to protect themselves, which are made out of chitin. Because these exoskeletons are relatively inflexible, arthropods molt as they grow larger, which means they shed their exoskeletons.

Click! Introduction to Photography 101

Photography is much more complex than taking photos on a camera. Photography in its most basic definition dates back to ancient China, where the use of a camera obscura was first documented by a Chinese philosopher in the fifth century B.C.  A camera obscura is the phenomenon where a small pinhole on a wall of a dark room allows light to come in. On the wall opposite to the pinhole, an upside-down image of the outside is illuminated. The science behind this strange phenomenon lies in the basic principles of optics, the study of light. Light travels in straight lines until it is blocked by a material, in which case the angle of the light changes. This concept of capturing light and forming an image was studied for hundreds of years, leading to the invention of microscopes to look at tiny living organisms, telescopes to look at the stars, and cameras to take pictures.
