A Final Remedy

Sep.28.2010

By: Anonymous

These days it’s hard to find a cure for many sicknesses or illness we can get infected by. But now as we are improving technology, we are becoming more developed in many aspects as well as the things we need to survive. However some illnesses are still deadly and we do not yet have cure for them. One of them is chronic stroke. This sickness is caused by dead cells in a specific part of the brain; this can cause long term or permanent disability. Scientists have found a way to make these patient with this illness live easier. As these scientists worked on this cure they had found out that for many years other scientists were searching for a cure, and they eventually found it, but the cure was not permanent it would only last for a couple of weeks or even days . This specific remedy was different. The medicament was discovered Sep. 25 when a group of scientists took in 26 patients that suffered from aphasia and gave them the remedy for some time while they observed them. It turned out that it helped in a way that the were able to recover in a steady pace. Aphasia is another memory loss illness, this impacts the persons left side of the brain, where the language is processed, this means that they have a language disorder, very similar to chronic stroke. "Stroke is the leading cause of disability among adults, more than accidents or complications from Parkinson's or Alzheimer's diseases," said Fridriksson, director of the university's Aphasia Laboratory and an associate professor in the department of communication sciences and disorders. Still they haven’t found a perfect cure that could last forever, but they have found one that could last longer than the other one. This remedy helps them acquire skills that help them communicate easier. This remedy is called the fMRI. fMRI -- an imaging technique more improved and widely used in the past decade -- Fridriksson was able to see the healthy areas of the brain that "take over" the functions of the areas damaged as a result of a stroke.

I chose this article because I think its very interesting, and stunning the way humanity is improving, sure this isn’t a permanent cure, but as years pass scientists might discover a cure that could last forever, and help the patients suffering from this sickness, fall back to normal *or* get a chance to live a normal and happy life like most people on this earth. Hopefully things like this will get their chance to happen one day!

Glogster Reflection, Sodium

<iframe src="http://www.glogster.com/glog.php?glog_id=10207750&scale=100" width="960" height="1300" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" style="overflow: hidden;"></iframe>
I had a glogster presentation on a element. the element i have been asigned to present was sodium. Sodium has taught me many things, like how different element can combine, and which ones it cant. It is also pretty amazing to know the reactions of the many elements we use in our daily lives. If you think of it this way elements are all around us and they react around us they float around us and they combine as time passes. Sure we can not see them, put to us they are very important...why? Well most certainly because if we didn't know they existed (which we do) we would most likely be living without many foods, for example we wouldn't have tomato ketchup, and another daily item we use made out of elements is soap! Those are not the only things that would be hazard-es to live without, there would also be lots of explosions if we didn't know about elements. As you can see elements is one of the most essential thing in a humans life, and there are many reasons to it; why.

10 Things About Water That You Definitely Didn't Know!!!

1. 70% of every humans body is water!

I think this fact is very interesting, because having the thought of us being more than just skin bones, meat organs etc. but more than half of us is water. so its more than; skin, organs and bones! This is one fact that can be varified that we cannot live without water! :) 

2. At every humans birth about 80% of the infants measured weight is water.

When we were all babies, imagine us being more than half of our weight being water! That's pretty amazing. Water is pretty heavy, and with 80% of our body being water while we were little, we must have weighed a lot, for little babies!

3. Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain.

Well yes its true that we live off of water, and yes more than half of our body is water, but water can also damage us. Enough is enough! Never drink to quickly, never drink anything to quickly!

4. Somewhere between 70 and 75 percent of the earth’s surface is covered with water

 Sure i knew this before, we all did. but its amazing to find out that we are not the only ones needing water to survive, earth and the earths crust also needs this water in order to keep us standing and watering the rest of the plants we don't know about. i come to a conclusion that every single thing on this earth is needing water in order to survive, or be create. For example to make paint you would need water and some other substances, for making plastic you would also need water and other special ingredients. 

5. By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.

As much as we have water in us, we are also able to lose water. But this only tells you that once your thirsty, your instincts react, and emideatly you should go to the tap or bottle of water..

Watering the Air

Written: Feb. 10, 2010

Source: http://sciencenewsforkids.org/articles/20100210/Note2.asp

As we all know there are many problems with global warming. Global warming is the rise of temperature and that is exactly what’s happening on earth. We have to be more aware of this, and here are a few reasons why. I came over a to a very unusual conclusion; America is now having cooler summers and wetter days. Scientists are thinking that this is because of farming, and more farmlands.  The conclusions come to this; a group of scientists have been studying the weather changes in Chicago and 13 other states in the Midwest. The question is how and why are these temperatures getting lower and back to normal again? Well, at one point farming almost completely stopped, well at least the healthy way of farming. These unhealthy farming companies are becoming more aware of the harm they are doing and so they tried the healthy way of farming. More water and less chemicals, it makes them more money and profit, and now more farms are following in there steps. This means healthier plants, which brings us to healthier air, and the dropping of temperature! J Before I read this I wasn’t  as aware of what water does to the air to make the air warmer and this is what a very famous scientist said it does: Humidity is the measure of how much moisture is in the air. Humid air, which contains a lot of moisture, takes longer to heat up than dry air, Changnon notes. And humid air often releases its moisture through rainfall. As I said the plants are the ones releasing healthy oxygen and moisturizing the air, and this is how it all happens. It takes the water from the ground and through its leaves it lets it out in the air, which moisturizes the air, and cleans it.  But not all the plants let out as much moisturized air as the others; it’s mostly soybean and corn. The group of scientists went on another search and thought of finding out the difference of the past farmlands of these two crops, and now. Before these two plants covered only 57% of the farmlands in the Midwest, now it has increased by 97% of soybeans and corn covering farmlands of the Midwest. As we all notice there is much more rain these days, the days that would be hot and tiring are now wet and rainy, but this rain is only just part of what we call the Water Cycle and it is also a very important thing we need in life in order to survive.

My article was about how we can solve global warming and go back to the time where the air was fresh, and healthy to breathe,  and that there are may ways that help clean the air, plants and rainfall etc. This was very intriguing because I thought that global warming was becoming a life or death situation, but something can be done to fix it! J All these moisturized plants, fresh soil, the Water Cycle; they all have to do with many elements, and this article is mostly about how H2O can help us bring back the weather we can survive in and the life we need in order to stay safe and sound, in our beautiful and natural home, the planet Earth.

Blue Gold Question and Answers

1.  What rivers flow through your country?
2. Where do the rivers come from? (Include the countries that it flows through)
3. Are there any blockages? (Dams, hydroelectric plants)
4. What forms of industry are located on the rivers?
5. What springs/natural reservoirs are there in your country? (Lakes, aquifers, watershed)
6. Where does your country get their water supplies from? If it's from your country, do you ship/export water to different countries?

1. In Serbia the rivers that flow here are: Danube, Great Morava. South Morava, Tisa, West Morava, Sava, Drina, Kolubara, Timok. and White Drim.
2. Danube is the most shared river in Serbia, we share it with 8 countries!Germany, Austria, Slovakia, Hungary, Croatia, Romania, Bulgaria, Ukraine. Sava is another river thats shared in Europe, Slovenia, Croatia Bosnia and Herzegovina. Morava is not shared, this is Serbia's river. Tisa is a river shared through 3 countries in Europe Ukraine, Romania and Hungary. Drina is shared in 2 places Montenegro and Bosnia and Herzegovina. Kolubara is another river that is only found in Serbia, and so is Timok. White Drim is a river shared with Albania. 
3. The most popular dams and hydroelectric plants are Bajina Basta and   Djerdapska Klisura. 
4. Today many industries located on rivers are cut off because of pollution. Us Serbs are trying to consume as much energy as we can, and that's why we stopped these industries. The explanation of why and how is here http://www.drepr.org/
5.  There are many springs in Serbia one of them is at Ada. This is a man made gazer mainly used for entertainment and decoration. A natural spring is the Great Morava springs.
6.  A water supply in case of a drought we have our man made river Ada. Some people might think that its dirty because many people swim in it, but as it comes through our pipes, and out our taps the water would be fertilized and clean.

 1. This is one example of what happens when two different substances mix together. Some react and some don't react at all, but in this case we have a large reaction. The first reaction is the alcohol turns yellow and then as bromine dissolves, it turns red. 

2. Water is one of the substances that cant get almost any element onto fire, and that's what makes this video unique. When lithium is placed into a tray of water, flames come out of the lithium.

3. Another video that has a mix of water and cesium. Cesium when mixed with water it reacts somewhat like fireworks. 

4 Like other substances that are mixed with water, this one also gets lit on fire. This is what happens when the two potassium and water are mixed.

 5. When sodium and potassium are mixed they can create an extreme explosion that can be a hazard if not following the lab safety rules.

6. In this video we see how the liquid nitrogen spreads over the pool like a big blanket. This shows another reaction, liquid nitrogen and water in this case were not mixed...they cannot be. It will stay separated.

7. This one shows how two different substances can react. Not many substances react similarly, this substance fizzed up and made the beaker overflow. This a very unique project there are not many reactions like this.

8. Another reaction of how it explodes. I think that this explosion was not created because the gummy bears color or anything else, but the sugar and theother substance put in created this explosion.

9. It is not clearly explained what these substances are and why this happens when they are mixed.

Know:

• I understand and i know how to identify the most of it
• I know how to find out what the name of an element is, how many electrons it has, how to find out the atomic mass and the neutrons, and i know how many rings every atom has!
• There are many symbols and signs that represent radioactivity etc. those kind of things.
• I have also recently learned about atom families.=P
• I learned what Lewis dot means, its the number of electrons the most outer shell.
• I know which elements can combine together 
• I know how many electrons a element family is positive and which is negative.
• I know how to figure out how many electrons there is on every shell on an atom!

What i want to Know:

• How many elements are needed to create another?
• How many elements are there left to be discovered?
• Why do some elements radio act when they are combined?
• Why do some elements have a symbol that doesn't relate to the name or anything else?
