Howling At the Moon

   When most people think of changes during the full moon, they imagine men changing into hairy lycanthropes, but some people don't know of the other fabled changes said to happen in non-werewolf people. The truth behind the changes of the body and mind during a full moon are discussed in "Lunacy and the Full Moon" by Hal Arkowitz and Scott O. Lilienfeld on www.scientificamerican.com 
    Many people believe that the rising of a full moon causes odd behaviors. Even if this is not true, I find it interesting seeing the connection between the Roman goddess of the moon, Luna, and the word "lunatic." The well-known Greek philosopher Aristotle said that the brain was the wettest organ in the body and thus the most likely to be affected by the moon, which triggers the tides. The idea of the “lunar lunacy effect” or “Transylvania effect” was popular in Europe through the Middle Ages, when humans were widely reputed to morph into werewolves or vampires during a full moon.
    Even now many people think the magical powers of the full moon induce spontaneous actions, psychiatric hospital admissions, suicides, homicides, emergency room calls, traffic accidents, fights at professional hockey games, dog bites, old people streaking, and all manner of strange events. One survey revealed that 45 percent of college students believe moonstruck humans are prone to unusual behaviors.
   But that's just all what people believe. What's the fact behind it?
   The most accepted theory is that, because our body is made of 80% water that the pulling and pushing forces of the moon move around our molecules and cause us to do participate in unordinary shenanigans. This is not true because the moon's affect is so minuscule it wouldn't do anything to our bodies. A few other reasons this theory doesn't hold is because the lunar pull only works on open bodies of water, and even if it did work on our bodies, the tides are just as strong during a full moon as they are during a new moon, yet there is no "new moon lunacy."
   The next discouraging thing to those who believe adamantly in the lunar lunacy affect, is that there is NO proof that it exists.
Florida International University psychologist James Rotton, Colorado State University astronomer Roger Culver, and University of Saskatchewan psychologist Ivan W. Kelly have searched to the moon and back (pun intended) for any consistent behavioral effects of the full moon. In all cases, they have found nothing. By reviewing the results of 37 studies and treating them as though they were one huge study, they have found that full moons are entirely unrelated to crimes, suicides, psychiatric problems, and crisis center calls.



    I have never felt the impulse to do something especially peculiar during a full moon, nor have I ever observed others acting in a different manner as the moon hang high and full above us in the sky, so I'm not sure I believe in the lunar lunacy affect. I do find the idea of it very interesting though, and it is a myth in the science world that I almost wish was true.

I'm Not Crying, There's Just Some Genetic Coding in My Eye

   It is common knowledge that depression tends run in families, and women are much more emotional than men, but according to the article I read on Sciencedaily.com, our genetic coding has more control over our feelings than previously thought.
   In the article, "How Your Brain Reacts to Emotional Information is Affected by Your Genes," published May 7th, 2015, it discusses how carriers of a certain gene perceived positive and negative images more vividly than others without said gene.
   The experiment talked about in this article conducted at University of British Columbia studies people with and without the gene ADRA2b, which influences the neurotransmitter norepinephrine. Carriers of this gene showed a great deal more of activity in a region of the brain responsible for controlling feelings and detecting pleasure and threat.

   Study participants were asked to estimate the amount of "noise," or pixelation, put on images that had either positive, negative or neutral emotional content. Compared to non-carriers, carriers of the ADRA2b gene estimated lower levels of noise on positive and negative images, relative to neutral images, indicating emotionally enhanced vividness, or EEV.
   I'm not quite sure how the estimation on the editing of a picture can relate to emotional levels, but on the more scientific side of things that I can believe, carriers of the genetic code also showed significantly more brain activity reflecting EEV in key regions of the brain sensitive to emotional relevance.


   The results of this study prove to be a possible explanation as to why some people are more susceptible to things such as PTSD. This experiment also can give us ideas as to why some people are more sensitive than others. It may not just be the way someone was raised that causes people to react the way they do, but is also influence by coding our parents passed onto us. Further research is planned on this certain gene to explore emotionally enhanced vividness in different ethnicities, anxiety and stress-related mental disorders, and addiction.
