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.
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.
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
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.
In this lesson, we learn about the 3 shunts of fetal circulation: ductus arteriosus, ductus venosus, and foramen ovale of the fetal heart: functions, medical significance, when they close, medical complications, and remnant ligaments.
Ever wondered how plants grow or survive? In this educational lesson, we learn all about plant hormones, including gibberellin, auxin, cytokinins, ethylene, and abscisic acid.
For the average person, washing their hair every day or every few days is a matter of hygienic preference rather than necessity. Unless their work or pastime brings them in contact with dirt or involves physical exertion, it is unlikely that their hair would go from being clean to truly dirty in the span of twenty-four hours.
So, what is the true science behind our “dirty” hair and the ingredients in our shampoo?
Circulatory System: Heart Structures and Functions; Blood flows through the heart in the following order: body –>inferior/superior vena cava –> right atrium –> tricuspid valve –> right ventricle –> pulmonary arteries –> lungs –> pulmonary veins –> left atrium –> mitral valve –> left ventricle –> aortic valve –> aorta –> body…

What is the difference between Kwashiorkor and Marasmus? USMLE protein-energy malnutrition diseases; we explain the differences, including causes, symptoms, comparative medical charts.
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?

Phosphorus Part 2: Health Risks and Disadvantages. Part 1 of this article described the uses and advantages of the element phosphorus. However, there are also various health risks that come with using phosphorus in our lives.
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.
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.
In this quick, easy-to-understand lesson, we learn about the kidney’s development and renal embryology in 3 stages. Mnemonics & Kidney Embryology Quiz Included!
On April 10th, 2019, astronomers made a historical discovery within the enshrouded area: they captured the first picture of a supermassive black hole. Learn more about black holes with us!
The COVID-19 pandemic has people across the world self-quarantining, but what does that mean for the furry additions of our families? Are animals affected by the virus like we are?
You can probably find that phosphorus is the 15th chemical element if you look at a periodic table. You might also easily guess that it has the chemical symbol P. But what you may not know is that beyond these basics, there are many different applications of phosphorus that make it a significant part of our everyday lives.
Come learn about interesting factors about phosphorus with us!
With a majority of the world under lock-down and physical schools closed, teachers and students from various countries and continents are plunging into the digital age. Many schools have shifted into online learning, allowing for asynchronous learning to happen for students across different locations and time zones. However, from a scientific standpoint, how does online learning measure up to physical learning?
Does being alone at home make a person go insane? After weeks of social distancing because of COVID-19, people locked up in their homes may be getting bored and restless. Attending school, going out to eat, hanging out with friends — parts of their lives that are normal — are no longer possible. What is the science behind the human’s social brain, and what does isolation do to the brain?
Help, I smell like fish! Is this even possible?
Body odor is a fact of life. For many, this is a simple fix either through some deodorant or a quick shower, but for some unlucky few, a fishy odor always remain. This is none other than Fish Odor Syndrome, a rare genetic disorder also known as Trimethylaminuria (TMAU). Learn more about the biology behind Fish Odor Syndrome, the FMO3 gene, cures and treatments.
