The myth I am looking at is A conk on the head can cause amnesia (forgetting). This myth is about that a hit on the head can cause amnesia. Amnesia is a type of condition that wipes out all the past memory in a person’s brain. You can see this so often in movies. For example, The movie, The muppets, has a scene where kermit the frog got hit by the taxi and lost his memory after that accident. After that, there is a second accident that makes the him to recover from amnesia. It is a good event to use for entertainment, but if you look at people around you, it rarely happens that way.

Amnesia is caused by situations for example, stroke(It a problem that relates to the blood supply in the brain. Either a blood supply is blocked or a blood vessel in the brain ruptures is blocked), Encephalitis(brain inflammation that could be caused by a virus infection), oxygen deprivation( any situations that lessens the oxygen supply in the brain), skull fracture and some medicines(such as sleeping drugs).situations for example, stroke(It a problem that relates to the blood supply in the brain.

The myth came from entertainments such as movies and books. A example of a book is the book Before I Go to Sleep. The character, Christine Lucas, suffers from anterograde amnesia because a car accident. A example of a movie is Fast & Furious 6. The character, Letty Ortiz, suffers from amnesia because of a big explosion. As I have said, this is all not true.

This myth is a social issue. It does matter that this myth exists because it more people believe which car accidents that has an effect on the brain, could cause memory loss(amnesia). People believe in that the current model is right because a lot of movies, books explains that this effect is true by including the event inside the movie/book.

A better, current theory about the working of the brain is that amnesia is not caused by head injuries like car accidents, but caused by head damage inside the brain and the skull.

Comet probe may shed light on Earth’s past

SPACE IN THE NEWS- PHILAE LANDING ON COMET

 'Chasing A Comet – The Rosetta Mission' By: DLR German Aerospace Center

‘Chasing A Comet’– The Rosetta Mission’ By: DLR German Aerospace Center

After about more than 10 years of journey, the robotic lander which is Philae landed on the surface of the comet 67P/Churyumov-Gerasimenko on November 12th 2014. Philae and the mother spacecraft, Rosetta were roughly about 500 million kilometers away from Earth. Numerous spacecraft had spent several hours interpreting, and observing comet from above. However, until Philae’s landing, no one had ever placed researching lander on to a comet. The robotic lander has been sending back various photos of the comet to the European Space Agency’s Science and Technology Center in Noordwijk, the Netherlands. While Philae is snapping many images from the comet 67P, Rosetta is also orbiting the comet, and snapping many images from above. Scientists have planned to make Rosetta stay on the tiny celestial rock, until at least December 2015. But, the scientists are not expecting for Philae to stay for more than about four months because when the comet 67P gets near the sun, the comet will heat up heavenly. At the same time, the robotic lander will essentially get fried.

Comets and asteroids are thought to be the oldest relics of the solar system. People can’t go back to the past billions of years in time to see how the solar system was made. Therefore, comets and asteroids are the best option to see how the solar system changed and how it was created. I think that this has a relationship with the Big Bang Theory. Big Bang Theory is a very famous theory that talks about how the solar system was formed in 13.7 billion years ago. Well, in the theory, it also described about that asteroids and comets are formed from the leftovers when making the planets.

From the article, it also suggested that the comet 67P’s water could be the same type that make up the Earth’s ocean. The scientists noticed that most of the comets-they have studied-has a large amount of deuterium than Earth does. If the comet 67P do have the same thing, that would argue that comets are mostly made out of Earthly water. However, some people might instead argue that asteroids were the main source of Earthly water. Scientists have found an asteroid called Ceres that contained Earthly water. This asteroid is in the asteroid belt (which is between Mars and Jupiter). Some scientists think that it is big enough to be a dwarf planet. This asteroid actually condenses water just like a comet.

Rosetta and Philae are making more observations on the mysterious celestial matter.

The science in the article will affect the world socially because it will make the other countries to learn how earths made and what does comets and asteroids consists. Astronomy laboratories from around the world will communicate with this astronomy laboratory that is researching about comets and asteroids to help there to do this discovery more quicker. Having more people together working will make the exploration process go quicker, and there will be more ideas to use.

The science in the article can be beneficial or harmful to people and the planet. The science in the article can be beneficial because in the article it explained that comets, and the asteroids are the best way for learning how the universe evolved, which means that if we use Philae and Rosetta, we can find about a lot of information, and evidences to find out how actually the universe was created! We can have more information, and evidences to prove that the Big Bang Theory is correct nor incorrect. On the other hand, it can be harmful because it costs a large amount of money to do this exploring, and robotic landers are very easy to burn when it go near the sun. Robotic landers doesn’t last for a very long time.

KEY VOCABULARIES IN THE ARTICLE:

Relic: A relic is something that is leftover from a long time ago.

Condensation: if the water, which is vapored is cooled, it changes to water. It’s the change of gas to liquid. This process is called condensation.

Coalesce: Coalesce means to force and to join together many small elements to form combined mass.

Deuterium: Deuterium is one of the isotopes(one of the possible different forms of an atom of a particular element) of hydrogen. It has one proton, one neutral and one electron.

Banana Peel? The New Water Purifier!

A lot of people say that banana peel annoys their life because there is a slippery hazard. However, The Sao Paulo University have done an experiment, and found out that the Banana peels not only have a benefit on polishing shoes and silver, using as a fertilizer or curing warts, it can also be used as a purifier.

A researcher from the Sao Paulo University heard that the most healthy part of the banana is not the inside part, it’s actually the peel that brings people slippery hazard. That researcher did an experiment to investigate if the statement is true or not. The conclusion was that the peel had a lot of organic compounds such as carboxylic acids. 

Afterwards, he decided to do an another experiment to investigate if the banana peel will work well in polluted water. The scientist got a jar of water from Brazil’s Panama River, which includes copper and lead. Then, minced some banana peels into small pieces into the banana peel and they started observate. Consequently, the banana peel actually worked better than the other common purifiers such as copper, silica. It actually made the polluted water very clean and can be reused eleven times until it stops working!!

DID IT EFFECT THE WORLD ENVIRONMENTALLY??

I think that the science used in this situation affect the world environmentally. Even though copper and silica are cheap purifiers, they can still pollute the waters. A Banana peel is a low-costed thing and it can always be found anywhere around you, which leave the world with no chemical residue. Also, it can be re-used again and again until it stops working. Not only you can help the streets to be more clean, you can also make the polluted water to turn clean again so no animals that lives in the waters will die!

WORD BANK(from the article-Banana Peel):

WART- a small hard raised part on someone’s skin

PURIFIER- something used to remove dirty or harmful substances

RESIDUE- something that remains after a part is removed

ADVOCATE- to publicly say that something should be done

MINUSCULE- extremely small, tiny
