Weekly Science Report
Feb.1st 2010

1) Citation
Title: Chemist dies from self-made “chewing bomb”
Author: Anonymous Non-Profit Organization- RT
URL: http://rt.com/Top_News/2009-12-10/chemist-dies
chewingbomb.html?fullstory&gclid=CISX14SN0p8CFd1L5Qo

2) Brief Summary
This article is about a man named Vladimir Likhonos. He was a 25-year-old chemist who liked to dip his gum in citric acid. Accidentally he dipped his gum into an explosive powder instead of the citric acid, which caused a chemical reaction that resulted in his death.

3) Reflection
a.) I thought this article was pretty interesting that the chemical reaction between the gum, powder and saliva could create such a deadly explosion. I thought that it was interesting that Vladimir had his hands on that type of explosive material.
b.) I’m surprised that it resulted in his death, but it’s interesting that you can set off an explosion with gum, saliva and an explosive powder. It was also interesting that the man was so smart, since he had gone to Kiev Tech University and still made that mistake.
c.) I’m wondering what kind of powder the man had and what he could have been doing with it that he had it on a bowl on his desk. I would like to know more about different molecules that can mix together with each other to explode.

"Seeing red means danger ahead"
By Stephen Ornes

This article is about how a tiny molecule can make a difference in future warning systems. The article talks about a color-changing molecule that turns red right before it snaps.

This article was very interesting. I thought it was interesting because the article was easy to undertsand since they used examples in it to explain how molecules work. For example, what they said in the article which made it easier to understand how atoms are held together in a molecule was, they said to imagine you and friends in a circle and you guys all had joined hands. The joined hands would represent the chemical bonds and the circle would represent the molecule. The molecule used to turn the material's that it's in red is called a Mechanaphore, and to imagine what happens when that Mechanaphore breaks, imagine you and your friends in a circle again but this time imagine two of your friends let go and then everything turns bright red. This is why I thought this article was very good and easy to understand. Also what surprised me was how easily it turns red, and how it snaps seconds after. It was interesting learning that because I never knew that.

Although the article was very informative and explained everything nicely, I still have one question.
Why does the Mechanaphore turn red and snap?
Other than that I thought the article was very good and I enjoyed reading it.

The article I chose this week was called

Ahhh, the Seductive Fragrance of Molecules Under Patent
By CHANDLER BURR
Published: February 23, 2008
http://www.nytimes.com/

The article I read was about discovering new scent molecules for the perfumes and how there rising in prices. Also in parts they mention Takasago International, a major manufacture in fragrances.


I thought the article was okay nothing amazing some parts were dull like when they explained the perfume patens but the better parts were when they were taking about the perfumes industry.
What caught my eye in this article was companies like takasago spends billons of dollars finding new scent molecules paten them and started them up on the market, because they need there’s to appeal more then one of the around 600 perfumes introduced a year.
Givaudan produces natural and synthetic perfumery raw materials and employs the perfumers who use these materials to make fragrances. for Yves Saint Laurent, Burberry, Tom Ford and Hugo Boss Givaudan began creating molecules in 1902. “Our new molecule platform drives our innovation for marketing at Givaudan. We have over 50 researchers dedicated to new molecules” says the vice president. One other thing that Givaudan’s scientists develop over 2000 molecules scents are introduced a year barley 5 or 4 of them make it to the market

My questions are one why is there so little picked for market a year all those new molecules more then 4 must smell good?

My article is Making the most of a meal by Nicholas E. Curtis and Ray Martinez www.sciencenewsforkids.org

My article is about how a sea slug called The Elysia chlorotica. It has gained the ability to make chlorophyll in order to get food from the sun.

This article was a shocker; I did not think that animals could make chlorophyll. I thought that only plants made that molecule. Also they ate the algae to steal its genetic recipe for making chlorophyll. They are literally becoming what they eat! I picked this article because I really enjoy genetics. I thought copying DNA from one species and inserting it into another species was something only scientists could do with genetic splicing enzymes. I did not think an animal like the sea slug could accomplish that. Also, it’s the first time that plants and animals seem to overlap.

My most plaguing question is, were the slugs always doing this or did they just start doing it now? Also, if they were always doing it how were they built to copy the genetic information?

Clever way to break the nitrogen-nitrogen bond
By Rachel Ehrenberg
http://www.sciencenews.org/view/generic/id/50729/title/Clever_way_to_break_the_nitrogen-nitrogen_bond

My article was about how scientists found out how to break one of the strongest bonds, the nitrogen-nitrogen bond to achieve the much loved carbon-nitrogen bond. They already could do this but with their normal method ammonia (nitrogen-hydrogen) was formed and they would have to break the ammonia to get the desired effect.

I liked this article because of all of the new things I learned from it like nitrogen and nitrogen can form its own molecule and that the nitrogen-nitrogen molecule has 3 bonds. Some things that surprised me were all of the interesting facts about nitrogen like the fact that the carbon-nitrogen molecule is in nylon and that ammonia also has nitrogen in it. Did you know that 78% of the earth’s atmosphere is nitrogen? Well that’s what I learned in this article. I do have one question. If 78% of the atmosphere is made of nitrogen how is there enough oxygen for every living thing to breath?

fredysnitchelburger said...

the name of the article i read was called seeing red means danger ahead. This artical was by Stephen Ornes. I read this article in science news for kids.

This article is about a tiny molecule and how it can turn red right before your eyes

i liked this molecule because it was very interesting to me. It was interistenig to me because the story was very easy to understand.

What interested me was how a molecule could turn read write before your eyes.

the question i have for you is why and how does it turn red very quicly?


I would like to coment on yolanda figgle, manny lautner, and oregontrvlr. i picked theese thre people to comment on this week because they did a great job on writting the story down. i think they did it just how you asked and that is why i choose these thre people to comment on this week.

This is for my three comments:

fredysnitchelburger-
I liked how you explained what you read. It was interesting to read because I read the same article that you did so it was nice to see what another person's opinion was on it. If I were you, one thing I would probably do would be to check over your spelling, and probably explain more about what you read. Other than that I thought you did a good job!

yoland Figgle-
One thing I liked about what you did in your report, was that you extended what you read about. it was nice how you really described it. Also, if I read the article you read, I probably would've asked the same question. I thought you did an amazing job!

oregontrvlr-
Your report was very good. It really made me interested in the article you read because of the way you summarized it. Which I thought was good. When I read your report I too, thought it was interesting how you could set off an explosion with gum, saliva, and explosive powder! I thought you did a nice job!

danchoper gaoga said...

flaming wombat- i like your article because i like how you explaned alot about molecules and the research about nitrogen is really interesting.

oregontrvlr- i kiled how you explained about explosives because i find explosives very interesting.

fredysnitchelburger- i like your article because i kile things that are red like dinamite. dinamite i like because it is very explosive.

input-nice job i like how the snails can get food from the sun and i bet the snail has a ton load of energy like superman when he gets his energy from the sun!!!!!

fredysnichelburger- i like how you piked a article about color changing molecules but you could use alot more writing and more detail in your blog.

flaming wambat- your article was very cool because it was abuot nitrogen and i love to research abuot nitrogen and learn alot more about it.

Seeing Red Means Danger Ahead
By: Stephen Ornes
http://www.sciencenewsforkids.org/articles/20090513/Feature1.asp

Summary: A person explains why our bodies turn red in some places after getting hurt. Then she talks about tests she and her workers did on color changing molecules to prove it.

Reflection: I think this is a very interesting article. It told me a good amount of stuff I didn’t know. It also told me what people are trying to use this color changing technology for. I liked reading this a lot.

What I thought was really interesting in this article was that polymer, when containing a color changing molecule, turns red right before it breaks. Also, the red color heals its self with sunlight.

I would have liked to hear more of the stuff they are planning to use this knowledge on. What I want to know is, how will this be used effectively in the future?

Comment 1 for oregontrvlr

WOW I thought that exploding gum was something that only cartoons could achieve. You picked an awesome article (a bit sad though).

Comment 2 for flaming wombat

Your article must have been cool but your response left me confused. What is so lovely about the carbon-nitrogen bond?

Oh, and to answer your question about the 78% of the atmosphere that is made of nitrogen, there is a lot of air in the world and after the air has its oxygen removed it is
re-oxygenated by plants that breathe in carbon.

Comment 3 for Pengu97

I did not know that a molecule causes color change after you get hurt. I wonder what they are trying to use that color changing technology for. Your article really wowed me.

Thanks for the articles Pengu97, flaming wombat and oregontrvlr.

1)Our Plastic World
by Emily Sohn
Science news for kids

2) In this article they tell me about the harmful effects of plastic like the chemicals that are found in plastics that can seep out and harm your body for example things like phthalates and bisphenol which were the two main dangerous chemicals they talked about in this article.

3) I liked this article a lot because it wasn't like reading about a disease that happens to Tasmanian devils that didn't really concern me a lot but this article told me about one of the most important things in my life, plastic. You may wonder why I say plastic, well most of my things and probably yours to are made out of the stuff. Anyways I also liked how it warned me what kinds of things might have the bad stuff in it and surprisingly lots of stuff for baby's are made with phthalates and bisphenol which is really bad and I find wacky because those are the people that really need to stay healthy.

One thing I found to be surprising was what I had mentioned before which was the stuff about the baby things. Another thing that surprised me was that I read that it was safer to drink water out of a metal or glass then a plastic one. Another thing that really surprised me was that these chemicals can harm are hormones which is really bad because that means that if you drink out of a plastic bottle then you might have growth issues.

One question I have is that if plastic is harmful for the environment and humans why do we still use it we should find a solution to plastic so we can kick this thing. Which leads me to what I wanted to learn more about which is are people trying to create something to use in stead of plastic and if so what is it.

The following is a comment that is directed towards the viewing pleasure/displeasure of Pengu97 (I just wanted to cram as much words as I could in there)

I found your information interesting and I like how you left minimal information to make me want to read it. But I didn’t like was the fact that your second part of your response was similar to the first part

The following is a comment that is directed towards the viewing pleasure/displeasure of yolanda Figgle

I liked how you crammed in as much information as possible but that took away from your response all I saw was a continuation of the summary. Also you left out commas and periods and that were essential to the easy going boat that is my reading.

The following is a comment that is directed towards the viewing pleasure/displeasure of oregontrvlr

I loved your topic it was probably the best so far and I also found your questions to be intelligent and much needed. But you could have mentioned why he dipped his gum in citric acid unless you didn’t know…

1)Letting Molecules Do The Work (Filthy people)
http://www.sciencenewsforkids.org/articles/20091216/Feature1.asp
By:Douglas Fox Date:December,16th,2009


2)In this article they talk about how people are never clean. Because people are constanly sheding skin no matter what even after a bath. Also how people breath in invisible garbage every secound in the air that has 20,000 or more pieces of invisible garbege in each breath.

3)= a), b), an c)
a)I thought this article was intresting, from others. Well i like to learn about keeping our race of people around the globe clean an sanitized. Because the spred of these flakes off of our skin ca cause diseases to form and reproduce. plus try to keep our air clean from garbage, like with covering our coughs when we cough to pervent the spred of germs.

b)The main thing that surprised me about this article was that, one little invisible flake of ours can kill a whole entire world that is so miniature we can't even see it. plus after a shower i thought i was clean, intill now that i heard about the bad sheding that comes off of me even after a shower.

c)Well I would like to learn more about the garbage that is in the air. Because i would like to know about the stuff i am breathing in every day of my life. I would like to get more information about this from this scientist. why am i never clean when i come out of the shower? so the scientists that did this lab get back to me on this, Because i would like tom learn a little bit more about filthy people.

My article was called When Built-In Antifreeze Beats a Winter Coat
And I got it at Newyorktimes.com
My article mainly about how some insects have evolved and how they developed this thing called anti -freeze. And they make it by producing alcohol molecules. But the molecules don’t stop the bug from freezing they just slow done the process. Also they anti-freeze makes it so the fluids around the cells freeze in a controlled manner but the inside of the cell remains unfrozen.

I thought the article was ok, because sometimes they words got to scientific for me so it was hard to understand. But I thought that most of it was interesting sometimes, though I felt like the author would get off topic and then get back on really later on in the article. Something that really surprised me was that some insects that don’t have anti-freeze, or bury under the ground, they just deal with the cold and rarely can still survive. For example the article said that the Alaskan Upis beetle freeze at the normal temperature of -19 degrees but it has stayed alive at the temperature of -100 degrees. Also some arctic fish have anti freeze but it works a little different. Some questions that I have are, how can the bug still stay alive if the anti-freeze only works by the shells wouldn’t the outside of the bug freeze?

1) my articals name is alternative to open heart surgery from the website http://www.sciencedaily.com/videos/2009/0105-alternative_to_open_heart_surgery.htm by science daily

2)this artical talks about wich is better open or minta clip it was aboutt how this woman had blood flowing backward into the heart.

3) a what i liked about this aritcal was that i never knew blood could flow backward inhto your heart i injoied the artical it was very intrasting and if my parents ever got that i would recomend the clip

b)there was somthing i didnt under stand in this artical they never told us what age u could get this heart proplem and i learned that the heart has a hole and the blood goes back.

c) i would like to learn more of how you get this heart problem

4)i like pengu97 artical i never knew about that i thought it was just a minor thing when it turns red k now i under stand why my mom gets freaked out when i have a red spot after i hurt my self does every red thing have to mean danger ???????

Citation: The name of my article is Burrowing US Prairie Dogs use Complex Language (I know, long title) and it’s written By: Matt Walker. I found it at BBC News.

Brief Summary: My article talked about how prairie dogs communicate with each other through barks, yelps, and squeals and warn each other if there is a predator. What was amazing was that the sounds differed really little but they meant different predators we coming. According to each sound they respond a different way.
Reflection:
A) I thought that the article was incredible because the prairie dog react to the little sound differences. They are so incredible because they can make and understand their own language.
B) What surprised me was their reaction to the sounds, when they heard the sounds for a coyote they ran to their burrows lip. They stood up to look and watch for a coyote. Coyotes are sneaky and can come up behind the prairie dogs and eat them. Their reaction to the sound for a badger was to go to the burrows lip and squat down. They lay down because a badger will dig in their burrow after them, so they hide hoping that the badger won’t pick their burrow to dig in. The warning sounds were different for each predator.
C) I would like to know more about the other things they communicate about.

This is for oregontrvlr
I really like the article you picked it sounds very cool, and dangerous, also I think that your did a good job describing your article and I think that the reason he did that would be maybe for an experiment

This is for mannylautner:)
I really liked how you describe the example that was in the article, because that made it also a lot more clearly to me. Also I have the same question as you and I liked how you mentioned the difficulty of the article

This is for yolanda Figgle.
I like how used picked an article that involved objects that we use and how you stated the facts about the perfume companies. Also I liked your question and I like how you were honesty about if you liked the article or not.

Pengu97 said...

For teddy bear:

Your article really amazed me. I never knew that’s how a lot of bug survived in the winter. The one thing that I want to know is how did that beetle survive in that much cold.

For oregontrvlr:

That sounds like and interesting article. I really liked how now I know all about it, but I’m still interested in why it happened.

For flaming wombat:

Sounds like an interesting article. I like how you gave me some facts, and now I want to stop typing this and read it. I really found this interesting.

My article that I chose is called "One molecule smaller than a grain of sand, pictured for the first time."
http://www.dailymail.co.uk/sciencetech/article-1209726/Single-molecule-million-times-smaller-grain-sand-pictured-time.html

My article was about how scientist were able to take a picture of a real molecule. But how did they do it?

Scientist from IBM used an atomic force microscope to identfy a pentacene molecule. In the picture you can see the chemical bonds that make up the pentacene molecule.

The atomic force microscope is like an x-ray that can detect the atomic stuctures of molecules. But in order to perform this task, the scientist of IBM had to work under temperatures of -268C. This way any gas molecules or atomic vibrations wouldn't affect the measurements of the experiment.

This article stood out to me. I wanted to see what a real molecule would look like, rather than seeing a computer model. It surprised me becuase it's one event that will change the history of atoms/molecules forever!

Can the Atomic Force Microscope pick up other molecules besides pentacene?

How was the A.F.M built?

Will the next real picture of a molecule be more clear?

Sciencediva7 said...

My comments

Oregontrvlr: When I saw the title of your article was intriguing from the start. Even though that scientist made a huge mistake, he invented another cool chemical reaction.

Input: Your article is very interesting. I didn't think it was possible for another animal to steal DNA from algae!

gigitygigitygigitygo1234: When I read your article, it disgusted me a lot. But I did learn something. I want to be clean too, but how can we eliminate something we can't see with the naked eye?

"The Taste of Bubbles"
By Emily Sohn
www.sciencenewsforkids.com

When I came upon an article called "The Taste of Bubbles" I knew I could not resist it for two reasons: 1)Who doesn't love an article that includes the word "bubbles" in it? 2)As cool as bubbles are, I know nothing about them. When I first started reading, I was introduced to a scientist named Charles Zuker and a very strange experimant- five groups of "genetically engineered" mice who were each bred into three groups of tasting levels. Over the course of the article, I learned how the non sweet tasting group, the non sour tasting group and the non salty or bitter tasting group were effected by a can of fizzy soda, and how taste buds could alter how humans and animals all over the world tasted bubbles.

Personally, I thought this article was great. Not only was it interesting and different, but also the way it was set up was really helpful. It was perfect for my age level; the article even included a section of "power words" which acted like a mini glossary that explained what large words meant that were featured in the article. I also thought that the author chose a great subject to focus in on, and I learned alot from just reading a page and a half of writing. I especially enjoyed how the author/scientist used mice to reach their conclusion that when people or animals drink soda, their sour-sensing cells turn on and react to the bubbles.

Besides me being interested by learning that "umami" is another word for salty/bitter, I was surprised by many things as I read this article. First of all, who knew that when carbon dioxide (or bubbles in this case) comes into contact with protein, that triggers the sour cells on your tongue that are the same cells which detect fizzy flavors? Also, I never could have guessed that animals like mice have very simular taste buds to us, humans! I was very surprised to find out that scientists could easily change the way mice taste things, like sour,sweet, or even salty things.

I was very impressed in the overall article. But, I still ahve a few more questions for the author about her knowledge on bubbles. How could this "triggering on the tongue" happen so quickly in time for it to process it to your brain before you swallow? Also, what other animals have similar taste buds to humans? If there if a certain species, would you test it out on them if you had a chance? If I could choose, I would want to know more about the mice that were involved, like how old are they, what type they are, or if it effected the girls more than the boys.

Comments

teddy bear: wow, I thought that your topic was really cool but I didn't like the whole bugs staying alive thing because I hate bugs. But staying alive in -100 degrees, I think thats pretty cool.

jimbojones446: I think that its really cool that prairie dogs can do that because I always thought animals communicate with each other so that was really cool.

Pengu97: That seems like a really cool article that you read. I think that you did a good job summarizing it but I would like to know a little more things that you thought were interesting.

Katy Perry said...

Here are my comments for three different people:

1)eatsleepswim...

I really enjoyed reading your response to your article! I liked your setup of your article and how you labeled each section with numbers, it made it really easy to read and super clear. I also thought your article decision was smart, and it was super fun to read about it! I liked the part where you mentioned how harmful plastic is to us, it really made me aware of how many things I own that could be deadly. I also liked how I could hear you speaking to me through your response, it had a lot of voice behind it! Great Job!


2)flaming wombat...

I am a big fan of your responses, and I really liked your article you chose this time. I had no idea that 78% of the earth is made out of nitrogen! Wow! I thought the question that you asked was smart, I mean how is there enough oxygen in the world for so many people to breath? The article you chose sounded a little hard to understand, but the way you wrote your response made me know that you really understood it. Well Done!

Pengu97...

I loved your article choice! I've heard that title somewhere before, but after reading your response I was able to know what it really meant. I never knew that the red thing you get when you are hurt heals itself after it is in sunlight. I thought that was very cool. I also liked your response format, it was short but sweet and it was all crystal clear. One thing I would have liked to see more of is things you learned about polymer. Other than that, you did an excellent job. Keep up the Great Work!

The 'New' NASA will look back at Earth
By Andrea Thompson

Summary: This article is about what NASA plans to do with their budget and about a re-try of something they failed to do.

Reflection: I did enjoy the first part of the article, which was talking about how NASA is going to focus on earth science, particulary (sorry, cant spell) climate. The ending, thought, was basicly a bunch of comments from people who work for NASA, which was kind of boring. In general, it was an okay artical. I just wish that it didn't drag so much.

The only things I wanted to know was what NASA did in the past and why they want to focus on Earth science.

Amu Spade said...

COMMENTS =)

Pengu97: I thought your article about why bruises turn red was pretty cool. I'm wondering why they turn red though... Why not purple or green??? :| I'm going to ponder this...

Katy Perry: Bubbles! I love bubbles, so when I saw the word bubbles, I had to read it. Mice and human taste buds, I never would've thought they're similar. In general it sounded like a good article.

Yolanda Figgle: Your article sounded so cool! I never thought that molecules had scent (wow, I feel dumb now) on them and were used in perfume. But I always thought they used flowers and stuff........... Hmm...

“Break-Up Doesn’t Keep Hydrogel Down”
By Rachel Ehrenberg
http://www.sciencenews.org/view/generic/id/55483/title/Breakup_doesnt_keep_hydrogel_down
Scientists have created a self-healing gel that they hope will advance them in tissue engineering and environmentally-friendly chemistry. Surprisingly, the hydrogel is made of few, simple components.
I thought the article was very informative. It talked a lot about how the hydrogel was made and how it was a surprisingly challenging process when they made the special compound that made the hydrogel so super strong and capable of self-healing, and I liked that because I love when there’s something really interesting, and you look at the boring, tedious explanation, and you think:
“Well, now it’s not so interesting.” It’s very anticlimactic. But, the article was chock full of great facts about other competing hydrogels and such.
What really interested me in this article was the suggested ways the scientists said they could use the hydrogel for. They wanted to make “bigger structures” and “block slices” because when the gel is fresh, it has a sticky quality, so it would be like transparent LEGOs for the scientists to play with.
I might not want to hear more about the topic because I got a lot of information in the article already, but I do have tons of questions like
“Is it edible?”
“How can it be used for things besides science?”
“How can it be made edible?”
“What’s environmentally-friendly chemistry? How does it work?”
“What ‘large structures’ are the scientists talking about?” I always have a lot of questions after reading science articles.
It’s comment time!
For Flaming Wombat:
Your report was full of facts from your article that I could easily pick up on, like the one that said almost all ammonia has nitrogen in it. I really learned a lot from your article. But, I didn’t hear if you wanted to hear more about your topic. That sounds like a really interesting topic. It really does.
For Pengu97:
Your article was one of the more commonly used articles for this week. Just the subject matter alone was phenomenal. I mean, there are thousands of studies in this world, and injury viewing is a study now, supposedly. You were very straightforward with your facts, and I liked that because I didn’t need to search around in an entire paragraph for facts. Yours were just there. However, in your summary, you kept referring to the researcher as “she” and I didn’t really grasp who the “she” was.
For teddy bear:
Your article was a chance for me to learn something new, because I really never knew what anti-freeze was until I read your article. I now understand antifreeze’s properties very well, so I congratulate you upon that. Teddy bear, your article, as fine as it was, had a minor flaw. Your summary was a bit long, and I was just expecting a shorter summary. I’m sure you could have fit some of the smaller sentences into one big sentence.

Title: Fact or Fiction "High protein diets are great for losing weight."
By: by Don Bennett DAS
Website: http://www.health101.org/art_diet.htm

1. My article was mostly about how high protein diets can make you lose weight in an unhealthy way. Carbs are strings of sugar, and are a great way of storing energy. Carbs are converted by the body into glucose, which is the optimal fuel for the body (especially the brain). Most people think that this diet would work because doctors tell you it is the right thing to do in order to lose weight. Some doctors tell you this, but they just want your money, not help your health.

2.
a] I thought this article was very interesting because now I know that when I get fat and need to go on a diet, I will just go to the TV ads, not the doctor, because the doctors will try to steal my money.

b] I was surprised that doctors would use patients just to get their money's worth. I was also surprised that the diet did not work because form my knowledge i have heard of people going on the diet. I was also surprised about how the high protein foods recommended for these diets are animal foods, this is why the diet does not work. These foods must be cooked. Cooking destroys nutrients (one of the main reasons diets don't work in the first place; the body is continually hungry, not for fuel, but for nutrients, which are lacking in cooked food, so it keeps craving food). Animal proteins contribute to heart disease, immune dysfunction, colon and reproductive cancer, prostate enlargement, diabetes, and a host of less serious conditions

c] My questions are... why do sooooooooooooooooooo many people go on this diet when it doesn't ever work! Another question i have is what else happens to make you unhealthier, it only said that you lose muscle, but what happens.

I really enjoyed reading your article. I really liked the part where you mentioned how harmful plastic is to us, it mad me really scared! I also liked how you convinced me not to use bottles, because they are very harmful! Great Job! :)

2)flaming wombat...

I had no idea that 78% of the earth is made out of nitrogen! Cool! Your question at the end was very scientific! Also i thought you were very good for your overall reflection! Good Work! :D

Sugar Molecule Linked to Liver Damage
By Dr. Kim Mulvihill


1) This article is about how diet soda can impact you health.
2)this article narrows in on a specific problem. more and more children are being diagnosed with Fatty liver disease. this disease is most commonly found in overweight people.
3) The soda has a ton of carbohydrates. these carbohydrates also contain a molecule called fructose. Fructose is commonly found in fruits and vegetables, but it is also in sugar. Dietary fructose is what’s causing the biggest problem. The majority of Americans take in around 17 table spoons of fructose in a day. It has been drastically changed. it used to be around 3 table spoons a day. To much fructose in you diet can cause problems over time. I think this article was interesting, gross and very disturbing. But interesting. I think what interested me is how drastic of a change the intake of fructose has been over the years. I would like to know what exactly has caused suck a big change, that in a way scares me, but interests me at the same time. =)



Oregontrvlr….
Wow, that’s interesting. Citric acid gum….. Sounds pleasant. what I would like to know is what inspired him to do something like that?

Chemist Dies from Self-Made "Chewing Bomb"
name: anonymous
http://rt.com/Top_News/2009-12-10/chemist-dies-chewing-bomb.html

A chemist named Vladimir Likhonos, 25, died from an explosion in his mouth. He liked dipping his gum in citric acid. But by accident he dipped it in a highly explosive poweder that was next to the citric acid. The explosion was caused by his saliva mixing with the explosive acid.

This article was interesting because i just thought it was amazing that something as simple as saliva, mixed with an explosive powder could cause an explosion.

What I was wondering was why he had highly eplosive powder at his computer desk, which was where it all happened.


1) oregontrvlr
I thought it was funny because we had the same article, and the same exact URL. It felt as if I was reading the actual article.

2) Pengu97
I liked your article because I get bruises in lacrosse and now i know what the red spot is. I would have liked to know more about your article because it would have interested me more that it already did.

3) flaming wombat
I liked your report because I learned things I never knew before. Like that 78% of our atmosphere is made of nitrogen.

I like that you made your article sound very good in your summary because it was worth reading. I thought that the article was easy to understand also and after reading your question I had the same question.

Input

I think that article is super awesome! It only read it because you made it sound so good. I have the same questions as you and I think that everything you said was very interesting to me too.

Soccerlovr

I didn’t read your article but from what you said I got it very well and I had the same questions. I find it very unpleasant to figure out that doctors will try to steal my money if I want help with my health but it’s good to know that.

Molecules That Changed The World
Author:unnamed
http://www.cosmosmagazine.com/news/2403/17-molecules-altered-human-history-molecules-changed-wold?page=0%2C1

The article had molecules that gave us inportant resoreses. I picked Polyethylene(C2H4)N the most popular plastic it is used in grocery bags, plastic bottles, etc.

I like the article because I learned some intresting facts like Polyethylene is found in chewing gum! Also more than 60 million tones of polyethylene are made each year!

I found this article very intresting because I learned intresting facts. I found out that the English chemist that discovered it in 1933 thought of it as a waste product now look at 70 years later its the most popular plastic ever used.

The one question I had was how do they use polythylene in so many different things.

COMMENTS

This is for oregontrvlr and Mr. Asiankid both of your articles were on the same thing and both awsome, your titles got me intrested in your articles. GOOD JOB

This is for you flaming wombat I had no idea that 78percent of the worlds atmosphere is made of nitrogen. GOOD JOB

This is for you gigitygigitygigitygo1234 your article was a little nasty now I know I will never be fully clean. GOOD JOB

citation:Small Molecule Drugs
no author shown
http://www.genengnews.com/articles/chitem.aspx?aid=1934&chid=4

summary:Zhu Shen (head of buissness development at Immusol)presented Immusol's idea of using small molecules to treat diseases that small molecules are not normally associated with. The molecules they use are structurally changed to become more potent (stronger) and to take on more desirable drug - like characteristics.

reflection:
a)What did you think about the aritcle? Did you like it or not? Why?
I liked it because it was an article that was not something you see every day. It was about scientists stepping back and totally changing a lot of stuff in the future of medicine.
b)What interested you or surprised you about the article?
I thought it was cool that the scientists who proposed this idea wanted to move back to clinical and pre clinical stages of medicine rather than move forward like all of the other companies. I also thought it was cool becuause Immusol was going to make the small molecules really different from what they were before and then use them to treat diseases that, in the past, have not been treated wiht small molecules.
c)What questions do you have about what you read? What would you like to know more about what you read?
I would like to know more about different types of diseases that the new small molecule drugs are treating and I would like to know how the small molecules are changed to be able to treat different types of diseases.

this is for oregontrvlr: The article you picked sounds really cool. I'm wondering why he had explosive powder next to citric acid. It probably wasn't the smartest idea to put explosive powder next to something he was going to dip his gum in.

this is for scaramouche9: I can tell a lot about your article from your summary and reflection, you did a really good job. I think it's really gross how much the amount of fructose people consume every day has gone up so much.

this is for Yolanda Figgle: I like your summary a lot, it was really good. I didn't know that perfume companies had to make and patent their own scent molecules, thats really cool.
