Sexual Differentiation and Gender Roles

As we evolve from zygotes to fully-functioning adults, we are influenced by a myriad of various factors, from the way we are raised to who we associate ourselves with. When I think of what I have become, I think of all my external influences- what I have read, whom I have met during my lifetime, the experiences I have had; what I rarely ever think of is my genetic makeup and how it has influenced me as a person. Out of the functions that genes oversee in the human body, the most intriguing is sexual differentiation, which is the development of a person from an “undifferentiated zygote” to a fetus, which will then evolve into a walking, talking, conscious male or female (2).

What is a Belief?

What is a belief, and why bother having any? After all, if nothing can be proven as true, why would we believe in anything anyway? But certainly, we believe things, even against all sensory input.

For instance, if you stand in the middle of train tracks and look at them going off in the distance, your sensory input tells you that they meet up yonder a ways. And yet, you don’t believe that. Why would you go against your perceptory input on this? Probably it is because you have prior experience with tracks, watching them while on a train or walking, and have had the experience of seeing them open up before you as you move. Or do they open up before you? Though your senses tell you they do, you don’t believe that either. You believe they are stationary, not moving. But if that is true, how come they come together at the horizon, but never where you are?

Lactose Intolerance

Do you feel sick after ingesting milk products? Do you have to stay away from foods that
contain milk or cheese? If so, you are possibly lactose intolerant. You might also be
allergic to dairy. The two conditions are not the same, though they share one effect on
people’s lives; staying away from dairy foods. We will not explore dairy allergies in this
paper.

Here we are exploring lactose intolerance. What is lactose intolerance? Lactose
intolerance is a condition brought on by a lack of the digestive enzyme lactase, whose job
it is to break up the lactose molecule during digestion. If you don’t have enough lactase
to break up the lactose in your digestion system, lactose will remain inside the intestine.
It can not pass through the intestinal membrane wall to be absorbed into the blood stream.
When the lactose is sitting in your intestine, digestive bacteria will do its best to
metabolize the lactose. In doing so, the bacteria put off large amounts of gas, resulting in
your experience of bloating, flatulence and diarrhea, all of which can be quite painful. (1)

Should You Get A Flu Shot? And Other Stories

About a week ago, I felt like I was getting a cold. Rather than down some DayQuil and move on, I decided to take a different approach. I entered into a small, patchouli-smelling store called Arrowroot on Lancaster and looked around for some alternative cold medicines and found one named Coldcalm. The directions said to let two tablets dissolve on the tongue every two hours, and the sufferer’s cold symptoms would be relieved. Hating cough syrup and interested, I decided to buy the package of white pills and was happy to find that they really helped. Even though I still had a cold, it was entirely manageable.

Then my mother called me, telling me to get a flu shot. It’s not that I am not scared of needles, but I don’t particularly like getting shots (although, who does?). So I decided to do research and see if the whole needle-in-arm event could be avoided this flu season. I found that it’s not necessary to be vaccinated, although getting a shot isn’t a bad thing. I know that I, for one, will not be going to the Health Center for a flu shot this year.

The Science of Homosexuality

Homosexuality is an issue that has sparked tumultuous debate in the United States, and has been brought to the forefront in the last fifty to sixty years. While the legal and social implications has captured the attention of the media, the lingering question of biology remains at the core of the debate. Is it possible that one is born with the characteristic of being homosexual, or is it solely a learned behavior embedded in cultural norms? Researchers since the nineteen-fifties have studied homosexuality in a variety of ways, through genetics, animal behavior, and even birth order. While few have come to a conclusive answer, important progress has been made since the time homosexuality was merely considered a mental disorder that could be cured.

Chocolate? As a Health Benefit?

Is chocolate really as harmful as the world makes it out to be? I remember coming home one night after trick-or-treating and gazing into my huge pillowcase full of candy. I can vividly recall selfishly eating most of it all in one night and feeling incredibly ashamed and guilty that I had done so. My mom spitefully reproached me with all the horrible things that were going to happen to me if I continued to act so carelessly. Chocolate has attained such a negative reputation throughout the years, and it is often referred to as the devil’s candy. Unfortunately, not many people know that this sensuous and sinful candy actually produces beneficial health related results.

Why do we sweat?

Every evening after finishing my yoga session, I leave the yoga studio feeling strong, calm, revitalized, and, above all, incredibly sweaty. The combined effects of a heated yoga studio and physical exertion always seem to challenge my body temperature, resulting in the feeling that every square inch of my skin is oozing with perspiration. My yoga teachers have always told me that sweating is very healthy, and it helps the body get rid of toxins and excess energy. In looking into this question of why we sweat, I will examine the biological basis for sweating, and why it varies from person to person.

Gaia: The Earth Lives with Us

Whether for spiritual, scientific, or ontological purpose, the matter of defining life is an ancient and serious quest. The Gaian theory of earth science – so named for Gaia, the Greek goddess of the Earth – proposes that the physical Earth upon which we live is just as alive as we animals and the plants are. The scientist James Lovelock proposed in the mid 1960s that the Earth, far from being just a mobile mass in space hospitable to animal and plant life, is a self-regulating ecosystem that calls on the fields of geology and physiology to explain its potential status as a live organism.

DDT vs. The Mosquito

The continent of Africa is one of the largest land masses of the world and known for its struggles with poverty, AIDS, and civil war. Yet an issue that hasn been discussed or portrayed in the media as openly is the issue of malaria; specifically, prevention of the disease. The World Health Organization (the WHO), has been grappling with this issue since the 1950's. Now, a resurgence of support for the employ of the pesticide DDT to combat the malaria- carrying mosquitoes has sparked controversy. Scientists and politicians seems to be going backwards on such an issue- it as if the environmental revolution never happened! That such polluting practices can continue to be allowed is unjust and exploitative to lesser-developed countries. What is even worse is the pro-DDT propaganda, which denounces the findings of scientists like Rachel Carson that DDT, in any dose, is lethal.

Veganism: What is it, and is it nutritionally healthy?

Many things that people take for granted, such as butter, milk, honey, cheese and gummy snacks are off-limits to Vegans. Even things like some multi-vitamins use animal by-products in their processing or composition. Vegans, for several reasons, will not use or eat anything that comes from an animal. This differs from less strict forms of Vegetarianism which allow for the consumption of all things mentioned above. Veganism as defined by Wikipedia: "Veganism is a philosophy and lifestyle that avoids using animals and animal products for food, clothing and other purposes"[1]. These life choices are often times controversial and seen as somewhat radical. Many people do not know exactly what is the difference between veganism and vegetarianism. It has also been debated for several years whether or not this lifestyle is nutritionally sound. This paper seeks to explore some different aspects of veganism and help to further a discussion on the health of a Vegan way of life.
