Immunology 101: Innate Immunity vs. Adaptive Immunity

Innate vs Adaptive Immunity: What are the differences between innate and adaptive immunity? The human body has two protective immunological systems against pathogens: the innate immunity and the adaptive immunity. In this quick and easy lesson, we will explain the differences between the innate and adaptive immunity. The innate immunity and adaptive immunity differ based on the type of components that are used to protect the human body. For example, the innate immunity consists of neutrophils, dendritic cells, natural killer cells, macrophages, complements, physical barriers. On the other hand, the adaptive immunity contains components such as T cells, B cells, and antibodies to protect us from viruses, bacteria, and other pathogens.

Art in Space

When discussing space art, one can mean at least two different things. The term can refer to art made on Earth that is then sent into outer space, or art produced while in space. Going with the former definition, our exhibits come down to Earth’s closest neighbor in the Solar System and the rest of the cosmos.

Cardiac Arrhythmias: Definition, Types, Symptoms, and Prevention

The heart’s function is to consistently move the blood in the body for the blood to spread nutrients to other body parts or to be replenished with oxygen and nutrients from other respective organs. The heartbeat is a way to understand the pace at which the blood is moving and how quick the heart is pumping itself. A heartbeat changes based on its environment. Running and high-intensity movement causes the heart to increase its number of beats whereas resting may lead to a lower heartbeat for the low amount activity that does not require as much oxygen. Depending on the difficulty and intensity of each activity, the heart accommodates via changing its pace to fit the body’s needs. In certain cases, however, a cardiac arrhythmia occurs and can lead to different cardiac issues that may or may not be harmless. Cardiac arrhythmia has affected millions of people in a multitude of forms. This article explains the basics of this condition such as heart block and bradycardia. The article is solely for educational purposes and not to diagnosis. What is a Cardiac Arrhythmia?

Taxonomy: History, Definition, Classification, and Taxonomy Mnemonic

Cougar. Mountain Lion. Puma. What do these animals all have in common? Believe it or not, they are actually all names for the same animal! Because this feline spans such a large area, different areas call it different names. As you might think, this could get confusing if scientists try to discuss the same animal, so what do they do? They use taxonomy.
Taxonomy is the science and process of organizing organisms into categories and naming them. Every species of animal has a unique taxonomic, or scientific, name. A species is a group of organisms that reproduce among itself and produce offspring. The scientific name is used by scientists all over the world for ease of communication. After all, it is very important to be specific in science. For example, the scientific name of the cougar/mountain lion/puma is Puma concolor. The name cougar/mountain lion/puma refers to the animal’s common name. Organisms can have many common names used by the public, but when scientists are referring to them, they use the scientific name. Domain Kingdom Phylum Class Order Family Genus Species

Oceanic Forestry: Coral Farming and Biorocks

Climate change affects the entirety of the earth’s surface, and nowhere more so than our oceans. While our seas cover about two-thirds of the earth’s surface they absorb over ninety percent of the additional heat attributable to global warming. Both land masses and bodies of water absorb and reflect solar radiation that rebounds off of the greenhouse gases trapped in our atmosphere, but the latter is generally more absorptive and holds on to heat longer due to differences in physical properties. This of course has led to increases in global seawater temperatures, which has and continues to endanger several aquatic species. This article will examine one of those species and go over human efforts to preserve it.

Get the most out of your time: How to Study Effectively – Top 5 Study Strategies

Finals, midterms, SAT, ACT, Accuplacer, the list of tests we have to prepare for is seemingly endless, and the studying that is required for each one appears to be a long and arduous process. Yet it doesn’t have to be that way. By organizing your time and your workspace, using effective study and review methods, and sticking to a study cycle, you can navigate through the process of studying as painlessly and as quickly as possible. Here are Top 5 Study Strategies – Study Smarter, More Effectively, Not Harder

Loanwords and the Evolution of English

For all its complexities, and thanks in part to them, English is a highly versatile language. Several other languages have government affiliated academies that dictate their proper usage, voting on things like the addition of new words. No such body exists for English, making its development less top-down and more of a dialogue between those at the top and the general masses. One area where this can easily be seen is with loanwords.

Debunking the Middle Ages

One way of looking at history is in terms of progress. Many historians and fans of the subject laud Rome for its advances in military organization, infrastructure, and civics. Similar adulation is often heaped upon the Renaissance for the strides made in philosophy, arts, and sciences during that period, which in turn set the stage for the Age of Enlightenment. But what of the time between shining antiquity and the rekindling that was the Renaissance? lternately called the Dark Ages, the Middle Ages, and the Medieval Ages, the time period from roughly the 5th century to the 15th century is usually framed in the West as its own era of history.

Rewilding and Not So Wildlife

The basics of rewilding (at least in North America) are the Three C’s: Cores, Corridors, and Carnivores. Rewilding was developed in the 1990’s as a new approach to ecological restoration. Proponents have characterized it as being active rather than reactive. What this means is that instead of viewing conservation as stemming a tide or becoming shepherds to ever-declining animal populations, rewilding is focused on restoring the equilibrium of ecological systems. This is accomplished through a variety of methods that are grouped together under the Three C’s.

An Overview of Shorthand: History and Types of Shorthand

Shorthand is the use of abbreviated spellings and or simplified symbols to record information in a quicker, more compact form. The opposite of this is longhand, which generally uses either block lettering or a cursive script. While it takes longer to fully write something out in longhand, all or most of those fluent in a given language will understand what is written down, as opposed to shorthand, which requires special training. In light of modern recording and word processing technologies, the decline in shorthand’s use seems inevitable, with newer inventions allowing those who only known longhand to reap the benefits of shorthand. And yet several shorthand systems thrive in a few niche industries. To fully appreciate shorthand and its resilience, one must go back to its origins.

Macroeconomics: The Definition of GDP and Its Implications

GDP is the universal measure of income among different countries. We’ve heard of the term GDP multiple times, but what exactly is GDP, and how do we measure an entire country’s income? GDP, Gross Domestic Product, measures the total value of all final goods and services produced in the economy of a country during a given year. Important points that need special attention in the definition of GDP are ‘total,’ ‘final,’ ‘country,’ and ‘a given year.’

AP Calculus: Limits and Continuity

A lesson plan look at the relationship between limits and the continuity of a function for calculus. In the last article, we started talking about limits and their applications for analyzing functions. In this article, we will look at how limits can be used to determine the continuity of a function at a point.
