How Racial Profiling Can Hinder Job Performance
“How can job performance be hindered by racial profiling?”
Racial profiling adds to stress. Individuals who are affected have to constantly be aware of how they may be watched and possibly pursued. This stress adds an extra psychological burden when performing at a job, leading to counterproductive effects on focus. This is How Racial Profiling Can Hinder Job Performance. To counter this, organizations and governments must actively invest resources into not only supporting affected communities but the institutions and systems that cause this pain. The productivity increases will go a long way to creating a truly just, resilient, and sustainable society.

How Air Pollution Leads to Death
“What is the link between air pollution and morbidity?”
Air pollution ravages quality life, cleanliness of cities, and purity of the air. All of this is from the result of toxins found in the chemical reactions that produce such pollution. When ingested, these can cause long-term medical issues such as cancer and lung diseases which eventually leads to loss of life. This is How Air Pollution Leads to Death.
“Why do tongues work?”
One of the most fascinating facets of the human body is the tongue. Its ability to move food around in one’s mouth without any bone structure is quite marvelous. However, how exactly can it do this? Well, let’s use our scientific mindsets to find out. If we analyze our tongues further, we should see that these appendages are in fact in fact constructed of muscular material. Because of this, they have an inherent flexibility where any region of the tongue can lengthen, shorten, twist, or bend at any time, allowing for a wide arrange of movement. These Muscular Hydrostats can be found in many other animals, such as the tentacles of octopi and the Trunks of elephants. Because of their diverse applications in the animal world, engineers are researching how to implement similar materials into robotics systems
What can walking can do for you?
“So what can walking do for you?”
- Do you ever feel a bit gloomy or sad? Well, maybe all you need is a nice brisk walk. Studies have shown that taking time for a nice brisk walk can activate the release of chemicals which work to boost your mood and make you happier. (Rosenberg, Yael 2016)
- Would you like to feel smarter? According to research by the Beth Israel Deaconess Medical Center, individuals that commit to a regular workout stimulate the growth of nerve development. (Goldstein, Lev 2016)
- Want to prevent or reduce the risk of developing heart disease? Since walking is an anaerobic exercise, your heart will be strengthened by it. And with a stronger heart, you will be able to better resist the development of heart issues such as heart disease (Rosenberg, Yael 2016)
- Want to lose weight? Nearly any type of exercise will cause you to lose weight. Through walking, you can burn off those calories that you have been holding in for a long time, allowing for a healthier weight range. (Goldstein, Lev 2016)
- Do you ever just want to relieve yourself of some stress? Walking is cardiovascular in nature and can commence stress reducing endorphins to develop and takes your mind off the harmful things in life. (Rosenberg, Yael 2016)

Why you get sick from reading in a car
“Why do you get sick while reading in a car?”
Have you ever noticed how you get sick when you read in a car? Well, you have nothing but your own body’s physiology to blame. To estimate your location, your body receives some of its spatial information from its inner ear and eyes. When you are concentrating on a book, all you see is the stationary tome, but your ears will be listening to cracks, bumps, and changes in velocity. This incongruity of perceptual information will cause your brain to become disoriented and induce motion sickness. To avoid such an issue, try looking out of the window from time to time during the vehicular voyage.
Coal Worker’s Pneumoconiosis
“What does coal do to the lungs?”
Coal dust does not decompose in a human body. And since coal miners have to sustain long-term exposure inhaling such material, it would only be logical that the coal dust would build up and permanently damage the body. Specifically, such individuals would develop something known as Coal Worker’s Pneumoconiosis, also known as Black Lung for the dark tint that the organs develop. Symptoms of Black Lung include shortness of breath, chronic cough, coughing up black mucus, high blood pressure, and heart problems. Coal Worker’s Pneumoconiosis is just another reminder that relying on outdated technologies will only destroy humanity and hinder progress.
How images form in the eye
“How exactly do we see things with our eyes?”
Everything that we perceive in this world is formed through our eyes. However, have you ever wondered how images can physically form in these biological objects? Well, let’s analyze this question scientifically to find out. If one were to take an eyeball and cut it in half through the midpoint of the pupil, they will find a lens just behind the cornea. If you were to then shine parallel light beams through this lens, then you would find that all of the light would focus on to the backside of the eye. The back of the eye will then transmit information to the brain, which will invert the image “in the mind’s eye” enabling us to see!
“What happens when bones weaken as they get older?”
The human body changes throughout it’s lifetime. And as one approaches an older age, the bone structure in the body begin to weaken. Specifically, the holes in cancellous bones will become exacerbated and largen, causing a loss in bone density. This loss in bone density reduces the strength of human bones. This brittleness could lead to bone fracture in case of an unforseen accident, such as a falling event. Doctors have termed this condition osteoporosis. To prevent the onset of osteoporosis, one should commit to a weight-bearing exercise and a diet full of vitamin-D and calcium
“What holds all of the different parts of a skeleton together?”
Skeletons are quite complex structures. The average adult human skeleton holds around 206 individual bones in it’s composition! However, how what connects these bones all together, and what allows for their range of movement? Well, much like a mechanical machine, these bones are connected to each other through the use of elements called bone joints. Bone joints come in three different types of varieties: Fibrous (allowing for no movement between the connections,), cartilaginous (allowing for limited movement), and synovial (allowing for full movement). Fibrous joints are utilized in skull connections, cartilaginous joints in back vertebrae, and synovial joints are used in the knees.
