The Importance of Water: Water Facts and Health Benefits

Water quenches thirst, is crucial when taking a bath, and is important when cooking. Yet despite the fact that it is all around us and used in our daily lives, there are many facts and health benefits about water that remain unknown to many people. 

Beyond Fuel: Petrochemical Products and Environmental Impacts

Petroleum (or oil) and natural gas are widely used sources of fuel. Around the world many transportation, energy, and heating infrastructures depend in large part on one or both of these hydrocarbon-rich fuels, petrochemical products. While in the past it may have seemed inconceivable that people would have to step away from fossil fuels, climate change increasingly necessitates greener alternatives. It is also hard to imagine life without plastics. For many applications, such as in healthcare, there may be no better materials. A future with zero plastic is neither warranted nor desirable, but the threats to various ecosystems are likely to force the development of greener and more sustainable materials.

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.

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.

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.

Is COVID-19 Going to Resurge? In the Winter? When Will the COVID-19 Pandemic End?

The novel COVID-19 is leaving astonishing traces of deaths and illnesses as it rapidly encroaches upon our everyday lives. Schools are closed. Unemployment is surging. People experience dreadful losses of their family and friends. Luckily, however, the exponential curve of COVID-19 seems to have flattened within the past few weeks for many of the countries, and some even seem to have downward-sloping trends. So, should we feel relieved and expect the curve to hit 0 soon?

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.

What are Vitamins?: Definition, Functions, and Health Benefits

Vitamins and minerals both help our bodies work properly, and they aid with functions such as growth and development. So what is the difference between the two? Simply stated, vitamins are organic and minerals are inorganic. This means that vitamins come from living sources, like plants and animals, while minerals come from elsewhere, such as the earth. Vitamins tend to have more complex structures than minerals, and because of this, are more prone to degradation via heat or chemicals. Today, we will be focusing on vitamins.

An Introduction to Skeletal Muscles: Properties and Physiology

The muscular system allows us to move and do our daily tasks. It also provides heat, stability, and blood flow for our body. There are three main types of muscular tissue: cardiac muscle, which comprises the heart muscle, smooth muscle, which comprises the linings of organs, and skeletal muscle, which are the muscles that help our body move. This article will focus on the physiology of skeletal muscles.

How the Environment Responded to Covid-19

The coronavirus pandemic may seem like one of the worst things that could be happening to the world right now. And although that might be the case for us, the environment is finally getting the break from human activity that it’s been longing for. With businesses shut down, traveling banned, and everyone in lockdown, traffic and pollution have been significantly reduced and it’s had some notable effects on nature. So while you’re stuck being quarantined, here are some cool things happening around the world as a result.
