Wave Power

By: Janet Rodriguez

Wave Power is the transport of energy by ocean surface waves, and capturing that energy to do useful work like electricity generation, water desalination, or the pumping of water into reservoirs. The machine used to exploit wave power is known as a wave energy converter. People have tried to widely employ this form of technology since 1890 and have been unsuccessful. The first experimental wave farm was opened at the Agucadoura Wave Park, in Portugal, in 2008. The way this form of energy generator works is straight forward and very reasonable. The waves produced by the wind contain energy that transferred from the wind to the waves. However, energy will only be present if the waves made are slower that the speed of the wind. In order for this type of energy generation system to work there needs to be wind, waves and some sort of energy absorber. Energy absorbers include an Oscillating Water Column, a Surface-following Attenuator (Line Absorber), or a Buoyancy Unit/Point Absorber. All of these energy absorbers include different ways into converting the wave energy into electricity. 

Some side-effects to wave power include that they are very costly, noisy and could harm the marine life. Many people that live on where wave power plants are located, complain about the amount of noise that is produced. When starting a wave power plant the costs are really high and a risk if the plant doesn’t succeed. The energy absorbers cause many problems with different species. Birds and other animals are always running into them and getting injured or dying. The PTC provides a tax credit for the production of electricity and the profit of that electricity to an unrelated party. The movement and distribution of this energy is not to complex. The height and speed of the wave are recorded and the amount of energy that comes out would be in units known as Kilowatts (kW).  

Wave Power cannot be used of grid because of its complex energy conversion. It could be useful for transportation, if you need to charge something electrical. Like a scooter, car, etc. This type of energy has a centralized system. All of the power relies on the waves. Without waves energy wouldn’t be able to turn into electricity to produce power.

There are many obstacles for this form of energy generation to be adopted. The initial cost to start a wave power station in very expensive. The machines are also expensive to repair, fix and maintain. And sea life can end up getting really affected by them. People also say that they are too noisy and drive people away from the location. The government could go observe the wave power stations in Brazil and see how they work. They also see their efficiency, qualities and how much is produced. I feel that if they see how effective and enhancing this come of energy conversion is, more people will start to adopt it.

San Diego’s “Frozen Zoo”

By: Janet Rodriguez

Tubes in which skin cells are kept

                For years many animals have been extinct, or on the border of being extinct, thanks to the humans species. Human Kind is very ambitious and selfish, thanks to this many other species have suffered the consequences. Animals are often hunted down by poachers for their unique characteristics. Elephants are often killed for their tusks, tigers for their fur and Rhinos for their horns. Many groups of people and organizations have started to take action in stopping this issue, one of them is the San Diego Zoo. 

Consequences of poaching

The San Diego Zoo in California has been working on a project since 1972, to try to help these animals and many others from becoming permanently extinct. The Zoo began to collect skin samples from rare animals in 1972, scientist hoped that these animals would be protected in the future were science would be more advanced. They made a good choice in doing so because that stem-cell technology is getting closer. The Frozen Zoo has more than 8,400 animal skin cells that represent more than 800 different species. The skin cells are kept in deep freezers (metal boxes filled with liquid nitrogen) with temperatures of -280 degrees Fahrenheit. The San Diego Zoo is not working alone on this project, Scripps Research Institute have been taking skin cell 

samples from the Frozen Zoo and turning them into stem cells. Stem cells as you may know, are undifferentiated cells in an organism that can change into other kinds of cells, like blood cells, skin cells, etc. After turning them to stem cells, they can be converted into sperm or egg cells. These cells could then be used to form an embryo and allow reproduction to occur. The Frozen Zoo will help us keep our interaction with animals and allow us to have the privilege of experiencing nature more effectively. Many people would like to see rare animals, making the San Diego Zoo really popular and busy. The Frozen Zoo would bring more money into the country, because not only will Americans come see the animals but so will other interested people all over the world. 

Where the Skin Cell tubes are kept

The Frozen Zoo has already made an impact on society. Many endangered animal have been relocated into the zoo for protection. The Zoo also has skin cells from already extinct birds, which allows them to be studied and help scientist gain more information. From these skin cells they can see what might have led to their extinction and help prevent other species from becoming extinct. The Frozen Zoo can also help animal species from becoming permanently extinct in the future. There are however some side-effects to this project, which many people use to stop this certain project. The Frozen Zoo tries their best to help out animals from extinction, but many argue that though they could recreate animals they can’t stop poachers from hunting them down. Another side-effect is that this type of technology requires a little bit more time, they’re still trying to come up with the best way to reproduce the animals. So this project may still require a little bit more time, but as genetic technology advances so will the project.

The Globalization of the Selfie

By: Janet Rodriguez

A selfie is a self-shot photo, usually taken with a mobile phone and posted online to social media sites.  The selfie is one of the most common pictures taken and posted on social media. (Mainly Instagram; Instagram is considered the home of the selfie) Right now there are about 40,000,000 pictures up on Instagram with the #selfie. That’s not including #selfies, #selfiesunday, #selfienation, #selfiee, #selfiesfordays, etc.. In January of 2013 it wasn’t even on the top 100 tags used on Instagram. The usage of the hashtag selfie was first seen on Flickr in the year 2004, but it took about a decade to finally reach its highest popularity point. In the year of 2013, the selfie began to gain popularity and fame on google search. The first recorded selfie was taken biochemist and metallurgist, Robert Cornelius, in 1839. When famous people started taking selfies and posting them, fans all over the world started to post their selfies as well.

Robert Cornelius (1839)

The global spread of the selfie has brought many problems to the social media world. There are people that view individuals who take selfies as narcissists. It’s mainly the women who are often viewed this way. There are individuals that feel that females who take selfies and post them on social media are only doing it for the attention of men. There are also people who view women taking selfies as a way to break stereotypes on women. Many times women are expected to be these perfect, beautiful and classy individuals, according to the male perspective. Cynthia Wade, a filmmaker and creator of a film called “Selfie,” says, “We spend so much time trying to hide our flaws because the culture has set it up that you have to be ashamed if you’re not perfect. I think girls are tired of it.” People like her view selfies as a way to celebrate ourselves and our imperfections/flaws. Psychologists believe that young adults take selfies as a way of finding who they are and their true identities. However, they also fear of how influential selfies are on the emotional health of teenagers. Many believe that the comments and likes on a selfie could lower/ rise a person’s selfie esteem. The lowering of self-esteem is obviously bad because it could lead to depression or illnesses. Most people view the rising of self-esteem to be good, so how can that be bad? The rising of self-esteem is good but to a certain limit. When a person’s self-esteem is high, they could end up becoming narcissists. Researchers have discovered that people who post a lot of selfies online, because they feel beautiful, have scored high on measures of psychopathy.

            Selfies have affected the whole world in many ways. The selfie has because extremely popular in the United States and has already influence the country’s social media. Many famous people in the U.S. post selfies daily and they make sure they look absolutely stunning. When fans see this they want to look as flawless as they do. This has brought a lot of money into the Plastic Surgery business in the United States. China has also seen how much selfies have gained popularity in their country as well. Recently a Chinese manufacturer unveiled his plans for a new smartphone with instant facial beauty support software, so that the consumers’ selfies come out flawless every time. Selfies have had a huge impact on the world and will continue to affect it in the near future.
