Power Pose, What about Power Dress?

Today in class Andrew talked about how different body language creates different power levels. After looking at the results of the research study, it was concluded (although the study was small) that using ‘powerful’ body language could, in turn, make you more powerful (higher levels of testosterone and lower levels of cortisol, which is the hormone balance of powerful people). 

One question that I thought about after class was if your body language can make your hormones more like a person of power, could the way you dress also influence your hormone levels to make you more powerful? I know we’ve all heard the saying “Dress for Success”, so, is it really true?

In one study, it was found that makeup and dressing nice can earn you more money (money, in my mind, tends to be in the same category as power). The study was conducted in Shanghi, China, and it analyzed data from different resources, looking at a persons category of attractiveness, how much money they spent on beauty products, and their earnings at their job. The study’s conclusion was that the more attractive a person is, the higher their earnings are, whether they are naturally attractive or utilize makeup is not a factor. 
Another study I found relating to how your appearance influences your confidence (or power) was not directly related to one’s clothing but one’s complexion. The study was once again observational and charted a person’s levels of confidence when their acne was bad, and after acne medication cleared up their skin. 
Although the studies I did find were not on actual clothing selection, it does tell us that someones appearance does matter for confidence and earning potential. Making a logical jump to the conclusion that overall appearance, including clothing, influences self confidence and power is what I took away from the studies I was able to find. 

HIV Funding: One Step Closer

Yesterday, President Obama announced, one day after World AIDS Awareness Day, a new initiative for HIV research, with a total of 100 million dollars of funding. This funding will be used to discover and research new therapies for people with HIV/AIDS, with the goal of finding a treatment that will put it into remission. 

We all learned about the virus in school, and how to prevent our own exposure to it by using condoms. HIV can also be spread through use of dirty needles, from a mother to her baby, and from other contact with bodily fluids. Once you contract the virus, you may or may not pass it on to someone else (it depends on your immune system and if you are taking your medications). hiv.jpg

Currently, 1.1 million of the 313.9 million Americans live with HIV. HIV as of right now has no cure. Many who had the virus. From the CDC website, I was able to access a guideline for treatments for someone diagnosed with HIV, the document was 267 pages long–how daunting of a task to trudge through that and decide which options are the best for you, especially when you begin to look at the prices of the drugs that you will need to take in order to stay alive.
A person infected with HIV has an average cost range of $2,000- $5,000 dollars per month. The new funding plan that was announced Monday December 2nd, 2013 will add to state’s funding for support programs to help people with HIV obtain medications at a semi-reasonable cost. 
Another place where the 100 million dollars worth of funding is going is to research for new therapies and treatments. Currently clinical trials are being performed on HIV preventative vaccines and new treatments, but more funding will allow more research and trials to be conducted, and new staff to be hired. Hiring new researchers is an extremely important part of finding new therapies or even a cure; fresh ideas and innovation is something that new employees can bring into a lab. 
The announcement of the increased funding is something monumental for the United States; it will allow Americans living with HIV to have access to cutting edge treatments, it will make their medications affordable, and it will bring humanity one step closer to eradicating HIV. The preventative HIV vaccine research, in my opinion, is extremely important. If we could vaccinate the population against an incurable virus, then it is possible to eradicate HIV from our world, just like smallpox. 

Anthrax: What should we learn from the 2001 attacks?

In class during the lectures about vaccinations, anthrax and its use as a bio-terror weapon was briefly mentioned. For those who are unfamiliar with the anthrax crisis, this article explains quite well what exactly happened and the government investigation of the attacks. 

The anthrax attacks (which occurred about 3 weeks after 9/11) are considered the worst bio-terror attack in American history. The attack left 5 dead and 17 in critical condition. Anthrax is

 curable with a large dosage of the antibiotic doxycycline, but it is only effective if it is treated almost immediately. As mentioned in class, our military personnel are currently the only people in the United States vaccinated for anthrax. Why? If anthrax has been used as a bio-terror weapon in the past, and has the potential to be used as one in the future, it seems logical to me that civilians would also be immunized, especially since the anthrax attacks of 2001 were asymmetric warfare (warfare that attacks citizens with the intent of inducing terror). Even a child contracted anthrax from the 2001 attacks. 
Looking at this transcript from an ABC News interview with the sole producer of the Anthrax vaccine and Barbara Walters, a more in depth explanation is given as to why the vaccine is not available to citizens at this time. The CEO of the company responded with vague answers such as “it will be made available for civilian use at the appropriate time”. Which raises the question, when exactly is the appropriate time? After another anthrax attack is discovered? To me that seems paradoxical: the point of a vaccine is to prevent sickness, therefore wouldn’t you want to administer the vaccine before a potential outbreak would occur? Just like they immunize the military before they could come into contact with the bacteria, not after. 
What seems even more odd is the time period it would take to produce the amount of vaccinations needed for our population: half of a year. Although I understand vaccinating people for a bacteria that is currently not found in our country is unnecessary unless they have the potential of coming into contact with the bacteria, it does seem logical to immunize people in the public eye who seemed to be the intended victims of the 2001 anthrax attacks, as well as to create enough of the vaccine in case another episode of bio-terrorism using anthrax were to occur.
Bio-terrorism is a pressing issue for the United States. After several threats of it by al-Qaeda and the cases of anthrax in civilian population, it seems like it is necessary to create a feasible, effective plan of action to take should another outbreak occur. 
In class we also discussed risk and how to make effective decisions by looking at it. I have calculated anthrax’s risk as a medium low possibility of exposure, but a high hazard risk as the disease usually causes death unless treated immediately and effectively through use of antibiotics. So, the risk is, in my opinion, still a high risk as bio-terrorism is still a real concern in the United States. Since our current chances of contracting anthrax are low because there is currently no anthrax in the United States, vaccination may not be a priority. Looking at the other risks we subject ourselves to everyday, like getting into a car, I still feel it is perfectly rational to vaccinate people against anthrax. 

Research Study at PSU: Rheumatoid Arthritis

While scanning through the research studies at Penn State that are seeking volunteers, I came across a very interesting one. It is a study seeking adult couples where one of the two has rheumatoid arthritis. My grandmother has suffered from rheumatoid arthritis for most of her adult life, and in the past 4 years it has consumed her, literally. She went from some joint pain (which is what most people experience) to having only 20% lung capacity (her arthritis starting attacking tissues as well, causing interstitial lung disease), her joints has literally disintegrated leaving her dependent on a walker or wheelchair depending on how strong shes feeling that day. She has had 3 knee replacement surgeries, 2 hip replacement surgeries, many surgeries on her wrists and fingers, shes acquired colon cancer from the potency of the drugs shes on to control the rheumatoid arthritis, and it goes on and on. I’ve watched this disease ravage her body and mind, and I can see the toll it has taken on her relationship with my grandfather. His role of being her her husband has transformed into being her ‘nurse’. He gives her iv medication, makes sure she takes her other medications on time, takes her to doctors appointments twice weekly (sometimes more), and has to help her do anything and everything because she cannot support her own weight on her brittle, crumbling bones. They love each other very much, but this role change can be hard to handle. They both get frustrated and she sometimes feels helpless and falls into depression for a few days. 

The research study’s description was eye opening to me. The idea that someone would be interested in a diseases effects on a person’s most personal relationships is something I never considered as important. Looking closely though, it can be very important in the recovery process of a person with rheumatoid arthritis. I still believe the most important issue at hand is finding a cure for rheumatoid arthritis, but if studying relationships of people with the disease can help make the process of healing and dealing with it easier, then why not? 
Currently, the research about supportive relationships and the healing process has been centered around eating disorders, addiction recovery, and different types of depression recovery. The articles about research conducted on the subject are mostly interview/anecdotal. Which raises the question does the support from close relationships actually help the healing process since the research methods weren’t conducted on a large scale, and the method wasn’t experimental. 
heart-in-hands.jpg
This specific article discusses some pros and cons of the interview method of research, and the largest issue in my opinion is the sample group you will attain. Where you find the people to interview is a large issue. You’re going to find people with the same circumstances in certain places, so it can be hard to generalize your findings to other groups. If you interview people at a high end Californian rehab facility that caters to Hollywood’s elite, then those results could possibly only apply to that facility itself. 
Therefore, using interview as the sole method of obtaining information can sometimes skew results. In order to attain good data, the interviewees should be randomized, and another method of data collection would be beneficial in interpreting the results of the study. 
The Rheumatoid Arthritis study being conducted by Penn State employs the interview method, as well as heart monitors (something a person cannot lie or manipulate). The use of both techniques makes the study more credible than if it was relying solely on interviews. The randomization of this study is also a benefit; the study is open to anyone and everyone who fits the profile to sign up!

The Debate of Nuclear Power

In my PL SC 419 course (The Bureaucracy), we’ve been discussing organizational theory. Last week, we specifically looked at the Three Mile Island incident, and the organizational disconnects that led to the human error that produced the partial meltdown. Now, most of us were not yet alive when this disaster happened (my fellow SC 200 classmates), but the view of nuclear power after the partial meltdown at TMI was grim. Even though it produced clean energy, the public wanted no more nuclear power plants to be built because of the possible damage it could cause if something went wrong, like it did on March 28th,1979 at TMI. The fear of a mismanaged plant was greater than the benefit of clean energy without carbon emissions (fossil fuel plants give off carbon emissions). American’s problem with nuclear power lied more so in the management aspect of it than the actual technical process.  

tmi.jpg

So, 34 years after the partial meltdown, we are finally starting to see nuclear power plants being built. Nuclear power has numerous benefits; it is a clean source of energy, it is a cost effective source of energy, and the technology to develop these plants is readily available. Some drawbacks people see in nuclear power is the disastrous reality if a complete meltdown were to occur (Chernobyl). Another concern is what to do with the radioactive waste that is produced. From a political standpoint, nuclear power plants could become targets of terror attacks, if the attack that happened on the World Trade Center was to happen on a nuclear power plant, the results would be devastating to the entire globe.
Currently, there are many plans for nuclear plants in the process of coming on line.  I believe that nuclear power is a good source to use to produce clean energy. Yes, the radioactive waste is a concern, but it is one that can be dealt with. The carbon emissions from fossil fuel plants are more of a demon than dealing with where to keep the radioactive waste from a nuclear plant. Another reason why I believe nuclear power is beneficial is because the threat of another accident has been greatly reduced since the Three Mile Island partial meltdown. The official report on why the partial meltdown occurred was lack of communication between plants (the valve that failed had also failed in several other instances, but had never led to a meltdown), and because human intervention of the controllers stopped the system from fixing the problem itself. Nuclear power is designed with checks and balances to make sure that if one of the pieces fails, there is a backup mechanism to correct it. When that valve failed, the system had started to fix it by running the water over the core like it was supposed to. It was only when the human controllers shut off the water did the meltdown begin. After the TMI incident, nuclear power plant companies realized they cannot operate a nuclear plant like a fossil fuel plant. They began reforming the managerial system as well as training employees to be knowledgeable in nuclear power to know what to do when something does go wrong.

So, do you feel nuclear power is a good thing? Or that it is simply too risky and we shouldn’t be building plants?

Cat and Mouse: From Foes to Friends?

As a kid, the cartoons that we would watch on Saturday mornings usually included Tom and Jerry. Now, everyone knows that cats don’t like mice, and mice don’t like cats, right? If there’s one thing Tom and Jerry taught us, its that cats like to eat mice! What if that’s not the case?

tom and jerry.jpg

The parasite toxoplasma gondii is known to inhibit a mouse’s innate fear of felines, however, even after being cursed of the parasitic disease toxoplamsois, the mice that have had the disease, or who have had the disease and been cured, fear cats less than mice without the disease (Hogenboom, BBC). These mice, although they fear cats less, do however have many adverse side effects of toxoplamosis like brain cysts. The parasitic disease also affects humans, causing pregnancy issues, but can change moods in patients with schizophrenia and can lessen the effects of Alzheimer’s. Now, the discovery of mice who have been infected with the toxoplasma gondii parasite has larger effects on the practice of medicine. The fact that the parasite, once cured, has lasting effects on a person opens the door to finding cures for other aliments. Infecting someone purposefully and then curing the infectious disease in order to get the neurological/other changes brings new possibilities for treatment of diseases.
Now, how exactly do we cure the parasite toxoplasma gondii in order to reap the benefits before it causes damage? Doctors usually prescribe sulfadiazine along with daraprim (used to treat malaria. If you are generally healthy, you do not need medication to treat toxoplasmosis, the parasite will go away in several weeks. If you are HIV/AIDS positive, you will need the treatment because of your lowered immune system (Mayo Clinic). So, could infecting a schizophrenic potentially change their moods and have other desired neurological effects? Potentially, after all, it did change a seemingly irrevocable relationship between felines and rodents.

Fruit Flies And Home Remedies

Everyone has some experience with those pesky little fruit flies that like to swarm around our kitchens, particularly near the recycle bin, trash can, and where you keep fresh fruit and vegetables. My boyfriend Nick’s apartment is no exception, and he has a decent amount of those buggers and they are the most annoying part of his apartment in my opinion (there’s several annoying parts, its a basement apartment, has no air conditioning, etc.).

Fruit flies are typically an issue in the summer/fall months, and start their reproductive cycle around your produce (that’s what the baby fruit flies eat once the larvae hatch). The total lifespan of a fruit fly from birth to death is about one week, but they can have up to 500 siblings born at the same time (which explains why it seems like there’s a never-ending stream of them!). Although fruit flies are normally just pests, they do have the potential to carry bacteria and contaminate your food (Potter para 4).

fruitflies.jpg

So, in order to get rid of these pests, my boyfriend, being the most innovative person I know, decided to create his own trap using a plastic cup, a banana peel, saran wrap, and some duct tape.

He placed a banana peel inside the solo cup, put a piece of saran wrap on top, taping it to the cup to make sure it stayed in place, and poked small holes in the saran wrap. The small holes let the fruit flies enter (they can detect the rotting banana peel), but it will not let them escape. After a day or so, the cup had a decent amount of fruit flies in it, and the kitchen was no longer home to 50 or so flying guests!

Nick was also a former student of Andrew’s; he took Science 200 in Fall of 2010! He is now a law student, but his innovation in solving the fruit fly debacle makes me think he should have majored in Entomology.

Aurora Borealis

Many of us have seen the Aurora Borealis, also known as the northern lights in movies. Some of us have been lucky enough to travel close enough to the north pole to see them in person (or to the south pole to see the aurora australis, southern lights).

So, what causes these beautiful lights to occur in nature? I personally have not been able to travel to see the northern lights; movies are the extent of my experience with them. The fact that such extravagant light shows can be created in nature amazes me, so I did some research.

Colorful-Aurora-Borealis-in-Finland.jpg

It turns out that the northern/southern lights only occur in the magnetic fields around the poles. Solar winds arriving at earth (about 40 hours after leaving the sun) follow the lines of the magnetic fields around the poles (which are generated by the earth’s core). Electrons in the solar wind then collide with atoms of either oxygen or nitrogen at various altitudes and create the colors that we see. 
Blue– nitrogen, altitudes up to 60 miles
Red– oxygen, altitudes above 150 miles
Purple– nitrogen, altitudes above 60 miles
Green– oxygen, altitudes up to 150 miles
*Aurora is what the light is called after the collision of the electron and the nitrogen/oxygen atom

All of the different auroras interact with each other, and that is why they sometimes appear as ‘dancing’. The lights are best seen from November to March, and the best places to go to in order to see the northern lights are around the magnetic field. Here’s a list of the top 4 places to view the Aurora Borealis (click links for pictures!). Unfortunately, the only place the aurora australis can be seen is from Antarctica, which is not easily accessible. You can catch glimpses of the southern lights from the bottom of Australia, tip of South America, and South Africa.

1. Troms�, Norway

2.Yellowknife, Canada

3. Fairbanks, Alaska

4. Kangerlussuaq, Greenland

After researching how the northern (and southern) lights are created, I can’t wait to travel to a one of these places and see them in person!

Your Living Instrument

bighead.gif

When I was in high school, I always took choir. I was a part of all the musicals we put on, and I just simply loved to sing. One thing my choir teacher always pointed out was that the voice is the only living instrument. He wanted us to take care of our voices just like you would a violin; to ‘keep it safe’ by drinking lots of water, not shouting, etc.

This made me wonder, how exactly does this ‘living instrument’ work? All the mechanics of the voice are hidden away inside our throats and chests; it is not like a grand piano where you can open up the lid and see the inner workings.

So, there are several parts that are used to get the final product of song when someone sings. These are the larynx (voice box), pharynx (the throat), trachea (windpipe), hard palate, soft palate, and diaphragm. All of these parts have a role in the process of producing the sound of singing. First, air comes out of the lungs, through the trachea, and into your voice box. The air causes the vocal cords to vibrate and the vocal cords release small puffs of air that are the beginning of a sound wave. The sound waves journey through the throat enhances it, so when the sound wave finally leaves your mouth it is a voice.

Now that you have created the basic sound, there are many ways to change the original product. One way of doing this is by shaping the inside of your mouth differently. Generally, a choral singing voice requires a lot of space in your mouth to get the wide vowels a choir director looks for. For Broadway singers, a more closed sound is what a director is going for. How can you do this? By lifting your hard palate. Lifting the hard palate creates the space necessary to make the vowels ‘wide’.

This is simply just a glimpse of how the voice works. For more information on the muscle groups and physiology of how the voice works, you can click here. While learning about the voice, what Andrew said in lecture really made sense. Science is all around us, and it is most certainly present in something that you are interested in. So, happy blogging fellow classmates! It is not as difficult as you think (and it is actually kind of fun!).

Here are some more links to great choral and musical songs!

Initial Blog Post

liberal arts.jpg

This is my first blog post for my Science 200 course! I decided to take this class because I am not particularly drawn to Chemistry or Biology and I need 9 Science credits to graduate. Although I did well in my Science courses in high school, they were not my favorite. I generally enjoy reading and writing more than math, which Science seems to have a decent amount of.

My current majors are Political Science and English, which are in the College of Liberal Arts. I enjoy the non-mathematical side of Political Science more so than the statistics side of it, but I do not despise it like some people do. Currently, I am also exploring a possible minor in Sociology.  
My majors are not Science related simply because I am more interested in these topics than Science, although they do include some aspects a Science based major would cover as well.
