Since we are about to start with cells, I want you to focus on cells in your Weekly Science Article Report this week.
Find some article that deals with cells and do our usual thing.
For a reminder, here's what to do for this assignment:
1) Citation: Here you will put the name of the article, the author, and where you found it (for example, the New York Times or Science News for Kids).
2) A brief summary: Here you will summarize the article in one or two sentences. This is to give your readers (including me) a sense of what you have read.
3) Reflection: This is the biggest part of your report. I am interested in your response to the article. Please address the following questions in your reflection:
a) What did you think about the article? Did you like it or not? Why?
b) What interested you or surprised you about the article?
c) What questions do you have about what you read? What would you like to know more about what you’ve read?

1) My article was called Experiment Shows Molecules Can Walk, but Can They Dance? The author of this article is Henry Fountain, and I found it on the New York Times website.
2) This article is about how people at a NYU and Harvard made a walker with two legs that is made with a strand of DNA.
3a) I thought that it was cool, just the whole idea of creating something new and different like that.
3b) The process of what this thing does is very interesting. The whole process (which isn't very long) is very descriptive, or that is what it seems like to me.
3c) I want to know exactly how this works, I want to see do what it's supposed to do. Besides that, I don't have any questions.
1. http://en.wikipedia.org/wiki/Nervous_tissue(nervous tissue cell, by i don't know)
2. The nervous tissue is the main component of the brain, the spinal chord and nerves.It is composed of neurones, which transmit impulses, and the neuroglia, which helps the propagation of the nerve impulse as well as provide nutrients to the neuron. Every time you get pinched, part of your nerve tissue is damaged.Nervous tissue is made of nerve cells that come in many varieties.
3. A) I didn't really like this article very much. It was too scientific, and I didn't understand most of it. Now i know not to use wikipedia.
B) It surprised me and interested me that whenever you are pinched, you damage your nerve tissue. I wonder how that happens.
C) I don't have any questions, except for why your nerve tissue gets damaged when pinched.
4. for bob: Your article sounds really cool, but I would like to know more about it, because the subject sounds like it would be cool. Good job!
A cell is the smallest living organism. Humans have an estimated 100 trillion cells within them. They are sometimes called the building blocks of life. Some organisms like bacteria and unicellular only consist of a single cell. 1 nanogram is the typical size of a cell. The largest cell is contained in an ostrich egg it is called an unfertilized ostrich
egg cell. It was discovered by Jan Evangaelista Purkyne in 1835 while looking through the tissue of a plant. After that he developed the cell theory.
I found this article at wikepedia.com and it is not written by anyone in particular.
I read an article that I found on Wikipedia. I learned a lot about cells. Like that cells are the smallest unit of life that is classified as a living thing. Cells are also the structure of all life. It was cool to learn all these things about cells that I didn’t know before. I learned that people have and estimated 100 trillion cells in their bodies. The largest know cell is the cell in an ostrich egg.
1) The Taste of Bubbles! By J. Chandrashekar
2) Studies with mice have shown how the same cells on the tongue that taste sourness also detect fizzy flavors! Before this scientists believed that the taste from bubbles comes from them bursting or popping on the tongue! It was a relatively long article so that is just a brief summary.
2) a) I enjoyed the article! I usually find science articles difficult to read but in this article I could take it all in and understand it! in the article they talked about how they experimented on mice. Its amazing how they could engineer these experiments and that it made them come to their final conclusion!
b) It interested me that scientists were researching this. I would have thought that they would be researching something of greater importance but as I read on in the article i realized that the more we know about the human body the further we progress in our knowledge as a species!
c) I don’t have any questions about the article, just maybe what gave these scientists the inspiration to research this.
name
My topic is about the sperm cell, the sperm cells origin comes from the greeks, it is the hapliod( cell having only one set of chromosome, which is like D.N.A)of a male gamete( mature male sperm cell)its joins are an ovum( a female egg) to form a zygote(cell produced by a male and female's gamete's), that developes into and embryo(wich is a futues)they're y and x chromosomes y is a male and x is a female
I found an interesting article about cells on http://en.wikipedia.org/wiki/Cell_(biology). It is about cells. I managed to get some good stuff out of the first paragraph, like that bacteria is unicellular (only one cell). Another thing that they said was that cells are the smallest units of life. Also, they said that the word cell come from the Latin word cellula, meaning small room.
I thought that this was a pretty good article, gave me some stuff I didn’t know. One thing that surprised me was that there are cells called Prokaryotes, which are cells that lack a cell nucleus. It had good information on cells, so I don’t have any questions.
Brain Cells Take a Break
By: Stephen Ornes
http://www.sciencenewsforkids.org/articles/20090715/Feature1.asp
Summary: A neurologist named Sydney Cash talks about what happens to your brain cells when you fall asleep. She also talks about electrical currents that show brain activity.
Reflection: I like this article for its information, because I’ve always wondered what happens to my brain when I fall asleep. It told me a lot of stuff and now I understand what happens a bit more.
What was really interesting to me was that our brains fall asleep because our neurons (brain cells) take breaks periodically. This allows you to sleep through most sounds and smells. What is also cool is that a EGG, or electroencephalogram, can only read the outside electric signals of the brain, so there are still more.
One thing I want to know is, what happens when brains cells die in your head. Wouldn’t they just pile up?
What Are Organic Molecules?
By Tami Port
Found on suite101.com
This article is talks about what organic molecules are, what they contain and what they create. It also talked about the four types of them that we were studying in class(Lipids, Carbs, Nucleic Acids, and Proteins.
I don't want to say that I didn't like it, but I found it quite boring due to the fact that I knew most of the information it gave me.
One thing that I learned and surprised me was that a synonym for the word carbohydrates is saccharide.
My only question is, how do you pronounce saccharide.
I would like to research more about how organic molecules are what makes living things.
This is to Pengu97...
I really want to read your article now. It sounds interesting. My guess is that when your brain cells die, they wouldn't pile up, they probably just disintegrate.
This is to timeblazer42...
I am glad I know now what the word cell, originally came from. It is now just more useful information. Good comment!
This is to Calvone...
Your comment was kind of confusing. Um..I think maybe you should have made it a bit more simple. Also, I don't think you wrote the name of the article.
I had to do another one because my first one was on molecules.
1- My article was called Vacuum-packed cells stay alive for days. It is by Philip Cohen, and I found it on this website http://www.newscientist.com/article/dn1439-vacuumpacked-cells-stay-alive-for-days.html.
2- It is about how people made cells stay alive for a couple of weeks by vacuum packing them.
3a- I really like this article because it is a discovery that I, as a not very experienced at all scientist can understand. And it is just really cool, the whole idea of being able to preserve the cells.
3b- What interested me was that something as simple as using a vacuum pack to preserve cells worked. They didn't use some fancy thing to do it, just that.
3c- One of my questions is: Is there something that they could put in the vacuum packed bag that could make the cells stay alive for a longer period of time. My other question is: Why would people want cells to stay alive for a longer period of time, is there a purpose or use for this?
Comments:
this is for ChickenNikeSoup...
I thought that it was good, but I'm pretty sure that we were supposed to do our reports on molecules.
this is for eye8AburgerJR...
I thought that your report was good. The article sounded interesting.
this is for xoxopicklelover...
I thought that your article sounded very interesting, and you explained it well.
1.) The name of my article was “Skin Cells Transformed Directly Into Neurons” and the author was Tina Hesman Saey. I found it at sciencenews.org.
2.) My article was about how scientists have discovered how to change skin cells into neurons. This technique is the same one used on mouse cells. If it is proven to work that means peoples cells will no longer have to be reverted to an embryonic state. This means it will be much easier for scientist to do skin procedures and to repair skin.
3.) A) I liked this article. I thought that it was really interesting and cool. I liked the article because it was like a new invention/cure for skin.
B) What surprised me about this article was that even scientist thought that this was almost impossible to figure out. One scientist said “It’s quite remarkable that you can jump over so many hills at once with just three transcription factors, and so quickly and so efficiently, This really blew me off the chair.”
C) the only question I have is; is this discovery linked to skin cancer. If I did any research I would just want to learn more on the whole topic.
Comments
This is for Bob…
I thought you choose a very interesting topic. This idea sounded really cool, and new to scientists. I wish I could find out more about your topic.
This is for ilovepickles4ever…
I thought your article was different. I liked how you mentioned the specific fact about getting pinched.
This is for xoxopicklelover…
I really wanted to read more about your topic. Your topic sounded really interesting and cool. You wrote a good amount of text, and I liked what you choose to mention about your article.
My article was called Cigarettes Might be Infectious by Janet Raloff. I found my article in sciencenews.org.
The article was about how cigarettes and tobacco could have a lot of hidden germs in them that people don't know about. The cigarettes can cause an infection just by handling one or putting an unlit one in your mouth.
I thought it was a good article, but it was a little hard to understand. I think it was aimed more for grow ups who understand science, but it was still interesting to read.
I thought it was surprising how just by handling a cigarette you could get a disease or and infection. Also, I was surprised by how many different germs there were, who's DNA laced the cigarettes.
I would like to know more about what part of the cigarette has the germs in it, and how do they get in it? Also, what kinds of diseases does it cause, and is it life threatening? I mean, I already know that cigarettes can kill you, but can the disease they cause kill you?
Genetic Engineering Advantages and Disadvantages
http://www.biology-online.org/2/13_genetic_engineering.htm.
Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms. This procedure is very controversial, in some countries it is illegal and for many against their religious beliefs.
At the Roslin Institute in Scotland, scientists cloned an exact copy of a sheep named Dolly. This was the first successful cloning of an animal. Scientists also made a rat that had a human ear growing on its back. There are some advantages and some disadvantages with the technique.
Advantages
• Hereditary diseases could be prevented
• Plants and animals could be custom designed for desired results
• Make trees absorb more CO2 and reduce the treat of global warming
• Possibility of wheat plants to grow insulin
• Implant genes that code for antiviral proteins
Disadvantages
• Irreversible effect with consequences unknown (Dolly’s health has severely deteriorated)
• Moral issues , involving religion
This was a very interesting article. This was an unfamiliar subject that made me think how advance science is today. I personally think that there are no religious issues with this process unless they are cloning humans for cosmetic purposes. I believe that God is the creator and a man or woman in a laboratory should not be able to create life. I think this procedure would be beneficial for sick people who are waiting for a heart or liver on an organ donor list. Theses organ can be reproduced in a laboratory so they may get a transplant. I think it is morally wrong to use this technique to clone a perfect or custom child (ie: color of hair, eyes, etc…)
Questions:
1. How long does it take to clone a human or animal?
2. How much does it cost?
3. Will scientist attempt to clone a human in the near future?
1.
The article I found is called:
"From Stem Cell To Any Cell," by Emily Sohn. I found this article at: http://www.sciencenewsforkids.org/articles/20051019/Feature1.asp
2.
This article is mainly about how Stem Cells can turn into any other type of cell. This is crucial because it could cure potentially fatal ailments, like stroke. For example, when you have a stroke, part of your brain dies. However, Stem Cells could be placed into your brain and create new brain cells, and now you have a fully-living brain. Another example of how Stem Cells work is this. If scientists but them together properly, they will create heart cells, a throbbing together, at the same time (just like a heart beats).
3.
A) I did like this article. I already knew about Stem Cells, and this article was a good follow up to what I already knew. I thought the article was very informative and clear, and easy to understand.
B) Like I said before, when the Stem Cells are placed correctly, they begin to throb like a heart. This is amazing, and it really interests me. I would love to know more about this.
C) Like I mentioned in B, the heart Stem Cells really interest me. However, I do have one question: How do the Stem Cells know to beat together? Once in the body they know because they recognize the surrounding materials, but in a petri dish, how do they know to beat together?
Comments
This is for xoxopicklelover:
I thought that your report was really good. The summary was short, but still really informative. I also liked how you were honest about thinking that this subject did not have importance, but then as you continued to read your mind changed about that. Great job!
This is for eye8aburgerjr:
I really liked your report because it was about cells in general. It really gave me a clear understanding of cells, and how so many of them make us up. However, the citation was at the end, which kind of confused me. Also, you did not include weather or not you liked the article, or what you found interesting about it. Other than that, great job!
This is for Pengu97:
I really liked your report, because I have also always wondered what happens to my brain when I fall asleep. Your comment had a lot of clear information, and was easy to understand. I like how you gave a specific example of what interested you. Great job!
Title: Cell Basics
Author: Mrs.Farkas
Where I got the article: Google
My article was the basics of a cell, such as living things are made of cells, the different types of cells and sko on...
I didn't exactly like the article. It wasn't very ineresting nor fun. I don't think the author did a very good job on this.
The only thing that exactly surprised/ interseted me was that one square centimeter of your skin contains around 100,000 cells!!! Who knew? (Besides Mr. Ardito)
The article states that "the cell has a unique and special job that makes all life possible," well, what does the article mean by that? Can't the author at least state one example???
This is for timeblazer42...
I think that you did a really good job on your report. I just really wish you could say who the author was... that might of helped...
This is for ChickenNikeSoup...
I think you did a great job on your report... if it was on molecules. Listen to what he said!!!
This is for eye8AburgerJR...
I don't think that you did a very good job. You only kept throwing out facts instead of saying if you thought what was interesting or not. You were only supposed to make a summary and instead you made an encyclypedia.
Honesty is the best policy, I'm sorry.
My previous report was from a site that was not news, so here is the actual report:
The article was called Cell transplants 'restore sight' from BBC News and the author’s name I couldn’t find.
The article was about how cell transplant can fix an animal’s sight. What it said was that U.K. scientists treated animals with similar eye problems as humans so they can see again. Apparently, they were able to help the animals see again by transplanting immature retinal stem cells into their eyes. How they did that was by taking early stage retina cells from a newborn mouse. Then they put those cells into a mouse which was genetically designed to have eye problems so it would loose its vision similar to how a human would. Next, the cells implant and connect with the existing cells in the eye, restoring some of the mouse’s sight. Next, they did tests which showed that the mouse’s pupils responded to light and that there was activity in the optical nerve, showing that signals were being sent to the brain.
I thought that this was a pretty interesting article. I never thought that cell transplant for eyes would be possible. Although one question I have is how do they genetically make the animal have eye problems similar to a human’s?
ChickenNikeSoup
I enjoyed reading your summary on molecules. You provided a lot of interesting information and details. But the assignment was to write about an article on cells, good job anyway.
Calvone
You chose an interesting type of cell to write about. I learned an interesting fact on the origin of the name. Is it possible to have both y and x chromosomes?
Pengu97
I thought your article was very interesting. I never knew that brain cells take breaks. I always thought that they are constantly working and that the brain never stops. When we sleep, we usually have dreams, if the cells take a break, what causes us to dream? Some people are deep sleepers, how do the brain cells compare to light sleepers?
UCSF researchers have found a molecular regulator that controls the ability of a male sperm to reach and develop the female egg, the finding has proven to treat male infertility and able to prevent pregnancy. The team biophysicists and biologists researched by developing a method that records to electrical activity of a single human sperm cell through a process called patch clamping. sperm cells that are quiescent in the male reproductive tract and why marijuana and zinc affect the sperm motility and female fertility.
I thought this article was pretty good it talks about somethings i cant understand later in the article but i knew fairly what most of the article meant. I really didn't have a lot of questions for the article kinda simple at some parts. The reason i liked it is because it sounded interest to and the things i didn't know what they were drove me to learn and get to understand the article.
I agree Timeblazer42 the article sounds really interesting and its smart them to take a mouse's posterior of the eye and replace it with a mouse's.
My information about cells was not really an article, just fun facts. It was off WikiAnswers, but still.(It wasn't me who asked the question though).
Basically, there were just a couple facts about cells. Like one was, "the largest known cell is an unfertilized ostrich egg cell," things like that were on the site.
I thought they were really cool facts. They were all things I didn't know, except for one. Someone misspelled a word, it was some type of measurement, so I would just like to know what the measurement was. Pretty much every fact they had surprised me actually, they were very abstract.
This comment is for ilovepickles4ever,
Yeah, wikipedia can be pretty confusing sometimes. Thats very interesting that you damage your cells every time you pinch yourself. I wonder if you damaged too many cells just by pinching them could you do serious damage? That thought is a little weird.
This comment is for timeblazer42,
Wow, that's going to help a lot of animals. I bet it took years and years to figure out how to do that. Those animals are going to be pretty happy. I like how you did a second article because you thought the first one was wrong, that shows a good honest person.
This comment is for xoxopicklelover,
That's a very funny topic to be researching, and thats a good question, I do wonder why the scientists decided to do that. That's also a very well written summary/questions that you did, it had very good questions and was well written. Good job!
For ilovepickles4ever:
Great review, you got some interesting facts in it. I would never think that getting pinched damages anything.
For CrazyCurls:
Great report, you had an interesting question.
For Pengu97:
You did a pretty good job on the report, I always thought that the brain is always active.
1) I read a article called “Chemo Does Not Cure: Often It Inflicts Damage and Spreads Cancer” written by Tony Isaacs, and I found it at http://www.NaturalNews.com/027028_cancer_health_cells.html.
2) It is about how chemotherapy helps sometimes with cancer but it often spreads cancer cells throughout the body, and some people choose not to have chemotherapy because it spreads the cancer cells. It also can cause irreversible damage to the immune system.
A) I thought this article gave me the information it said it would, and it also had a lot of facts. I liked this article because it was interesting, I learned a lot of stuff about cancer than I would have ever know if I didn’t read this article.
B) What surprised me about this article was that chemotherapy spreads the cancer cells I thought that chemotherapy was supposed to get rid of the cancer cells.
C) I want to know how chemotherapy spreads cancer cells. And how did they prove that chemotherapy spreads it.
CrazyCurls: I really liked how you explained your article and I liked your response to the article I found it very interesting. Good job.
stitchlover: I liked how you expressed your opinion when you said that you didn't like the article, I think that you should have added a little more. Good job.
Bob: I really liked the article you chose, I thought your questions were really good, and I liked your response. Good job.
1) This artical was called "Cells are the Starting Point." I found it from http://www.biology4kids.com/files/cell_main.html. The auther was uknown.
2)This artical was about how the cells worked.It also showed alot of different types of cells and taught me how important cells are for example, it explains that all living things on earth divided into little pieces are called cells. It also talked about how there were so many different types of cells.
3) a. I loved this artical so much. I loved it because it had alot of pictures and animations so it really made it easier to understand. It also used words that i understood and i thought that it was very kid friendly. Most of all i really loved the pictures. They really explained things well
b. Some things that suprised me in this arrtical are that if you were only made of one cell you would only be able to grow a certain size. It happens like that because it is easier for organism to survive if cells are there. I thought that was really cool and somthing that i really never knew.
c. some questions that i have about this artical are how many cells really are they in someones body. Is it possible to leave without any cells and just not grow? how do you count how many cells are in your bpdy? If you are doing a surgery are you able to see the cells? When you die do the cells die also. Those are just some questions that i have about this artical.
For CrazyCurls:
I really like your overview of the artical it made me feel like i, read it myself, and i should read more. I also likes the questions that you had. Wonderful Job!!
for stitchlover:
I really love that you exspresed that you did not like this artical i do not see that alot in some peoples writings and i think it added somthing extra to your writing. Taking Risks!!!!!
for Pengu97:
I really lovedhow you explained that the cells take a break. I thought that the brain needed to be working all the time for me to learn and think, but i guess not. Thanks for teaching me that!!!
The article I read was called "Cells are the Starting Point." I found this article on http://www.biology4kids.com/files/cell_main.html. The author wasnt listed on the article and I couldnt find it on the website.
The article I read was about the basic of the cells. It talked about the difference of animal-like cells and plant-like cells. It talked about the main parts of the cells an what there main purpose is.
I really enjoyed reading this article because it was very easy to understand and it was a nice overview of cells. I like how the article had diagrams it just gave me a good understanding of what they were talking about.
One thing that really interested me was how the difference between the animal-like cells and the plant like cells is so small. The only difference between them is that the plant-like cells have a protective structure calle a cell wall. The oter thing that suprised me was the fact that very simple organisms have no defenete nucleus.
I would like to see the comparison between human-like cells and plant like cells. Also the comparison between human-like cells and the animal like cells. I also would like to further explore cells because they seem like they could be an interesting topic.

This is for Bob
I liked the topic of yours and it was an interesting thing to read about. I also how you summarized it.
This is for CrazyCurls
I really liked your work, it showed that you put alot of work into it. I also liked how you put your own input into it.
This is for Kyla
I liked how you put examples in the summary. I also liked how your questions they showed you were actually interested in your article.
Sorry this is late my power was out last night and I got internet back just a little while ago.
1) Brain cells have natural resistance to HIV
by Andy Coghlan
http://www.newscientist.com/article/dn17523-brain-cells-have-natural-resistance-to-hiv.html
2) Neurons can protect themselves against infections with HIV. It is because of a protein that is called FEZ-1 which is made differently by neurons and it appears to lock out the virus! They want to raise the possibility to destroy HIV by using drugs or gene therapy to start the production of the same protein in cells that are other then neurons. this is mainly to the white blood cells which are known be be the most vulnerable to the HIv infection.
3) a) I enjoyed the article a lot. I like reading about finding cures to deadly diseases. It was easy to comprehend and i found it entirely interesting!
b) I was impressed at how scientists can discover theses sorts of thing about microscopic cells that we cant even see! The whole thing simply amazes me!
c) i do not have any questions! the article was a very easy to understand and i enjoyed it immensely!
comments!
This is for xoxopicklelover: I really found your article enthralling! the topic was very interesting and i too found it an odd thing to research and experiment on. Good job on a very well written post!
this is for Pengu97: I really liked reading your article! It was so interesting about what happens to your brain cells when you go to sleep! your summary was short and sweet but still quite informative. Good job!
this is for stitchlover: Well next time you should look for articles on science for kids! they have good articles that are easy to read and have a interesting story behind them. but good job on your post but the article you choose did not seem to be a story but simply the characteristics of a cell. But none the less your post was simple to read and very well written! good job!
i am sorry that this is late! i lost power twice and i just got it back now!
i am sorry this is late! i just got my power back and i tried to post this on thursday! i lost my work but i am re doing it now.
this is for ilovehchesecakeyesido97: I really enjoyed reading your article! it was easy to understand and i enjoyed it a lot! I really found it interesting about how neurons can protect themselves from infection with HIV. It was very well written! good job! :)
this is for miss0892: I really found your article quite interesting! we already know so many bad things about cigarettes, and now i ask the question why do it? I really enjoyed your post and it was very well written! Well Done! :)
this is for Kyla: your post was really good! although enjoyed it, it made me frightened! i always thought that chemotherapy could do no harm and only improve the situation. Now we learn that it can be only worsening the fatal disease. Good job! :)
1. Title: Kids now getting 'adult' disease
Author: Emily Sohn
Where I found it: Sciencenewsforkids.org
2. This article starts with a story about a girl who found out she had diabetes at a very young age. This story takes place in the 1960’s. Later in the article, it tells about the different types of diabetes. There are two types of diabetes: type 1 and type
In both types, the trouble begins with the body’s ability to deal with sugar.
3. a) I liked the article a lot. It was good because it gave a story about someone who had diabetes and that was very interesting to hear of. I didn’t know this much about diabetes.
b) It surprised me that diabetes was mainly caused by obesity. I didn’t know that. I also didn’t know that a lot of kids get diabetes.
c) I don’t have any questions.
4. This is for Bob:
b) Your article was really good, but I wanted to know more. GREAT JOB!
c) This is for xoxopicklelover. I really liked your article, it had great information. FANTASTIC!
d) This is for calvone. I liked your article, but there wasn’t that much information. Good job!
This is my extra credit!
1) Brain cells take a break
Stephen Ornes
http://www.sciencenewsforkids.org/articles/20090715/Feature1.asp
2) It has always been some what of a question of what is happening to your brain while you are in a deep sleep. Scientists have been researching this and have discovered that your brain cells are busy with activity! Neurons and brain cells that control electricity keep your mind going while you are in a deep sleep.
3) a) I really enjoyed the article! It was easy to comprehend and enjoyable to read! It was well written and a very interesting subject!
b) I found it very interesting as I too have always wondered what is going on inside your brain while you are asleep. The article was quite interesting and I would love to keep on reading articles involving the same topic.
c) I do not have any questions about the article. It was well written and I found it very easy to understand.
Comments
This is for ilovepickles4ever: your article was really good! I found it really interesting about and unfortunate how that woman had diabetes at a very young age. Good job!
This is for Summer09: I really enjoyed your post! It’s always nice to read a well written enjoyable post. I liked reading about all the different types of cells. Good job on your post! (By the way I believe that sports101 had the same article)
This is for C.96.M.27.K.12: You did a really great job on your post! It’s really amazing what we can discover! I found it really interesting how we can find out that skin cells can be changed directly into neurons. Your post was easy to understand but it was still a complex concept! Good job!
Here are my comments on your work:
Bob. Your report is good, but I think you could do better. The reflection is supposed to be a little more meaty. Also, your article is not really about cells, although it is about molecules, and so I am accepting it. I think you should redo your report and resubmit it.
I just saw your second submission. It is better. You do not need to resubmit anything.
ilovepickles4ever. This report is not acceptable. Wikipedia is not a news source. Please find an article from one of the news sources that I link to on the blog and resubmit your work. Also, I do not think your report is as good as it could be.
I just read your second report. It is better, but it is not about cells. Also, your reflection was a little thin. Please find a more challenging article and do a better reflection and resubmit your work.

Brain cells take a break by Stephen Ornes.
I found it at http:
//www.sciencenewsforkids.org/articles/20090715/Feature1.asp
This article is about scientist wanting to know about what the brain really does when is asleep. It is still working hard, though.
I like this article beacause it was short and simple but had a lot of info about cells and the brain. The only thing that surprised me was that they acually is taking the time to study this topic. I really don't have any questions and i would love to study this topic more. That is my article... hoped you liked it!
My article was called Turmeric Component Kills Cancer Cells, by Nathan Seppa. I found it here: www.phschool.com in the science news/articles section.
The article was surprisingly short, but it was about cells (cancer cells specifically) and how scientist discovered that curcumin kills them. (“Them” being cancer cells).
I thought the article was actually really interesting, and it wasn't to long and filled with boring information with no personality. So yes, I liked it.
I was surprised that in countries where their food is rich with curcumin, not as many people suffer and die from cancer. I also learned that tumor cells overproduced a protein called NF-kappa-B.
I would like to know more about if this could actually work – to be like a real cure. Also, I was wondering how the curcumin kills the cancer cells.
I dont remember if I commented on people's work yet so...
Kyla:
Your post was really good. It had all of the stuff in it we were supposed to put in. I htought the same thing about chemotherapy. It seems strange that is call accutally spread the cancer instead of cure it.
I read an article on molecules from findacticles.com but there is no author listed. The article was about cells breast cancer, hair lose, grey hair and what causes it. The article had a very wide focus it was about hair and what scientists are trying to do for it like finding a cure. Scientists know that there is a cure but they can’t find out how to do it. I though personally that the article was kind of blank like that it was not quit interesting enough but it is a very cool subject.
A mature sperm cell is about 0.05 milliliters long. The head of the sperm cell is covered by an ac cap and contains a nucleus of a dense genetic material of 23 chromosomes (any several thread like bodies). It is attached from the neck to the body containing mitochondria (An organelle in the cytoplasm that functions in energy production) that supply the energy for the sperm movement. The tail is made of protein fibers that contract of alternate sides, giving a characteristic wave like movement that drive the sperm through the seminal fluid which also supplies energy.
Calvone,
You have still not put in a reference to the article you are using. Please fix this.
The article I wrote was called The Nerve Of One Animal. I got this article from http://www.sciencenewsforkids.org/articles/20100120/Note3.asp. The author of this article was not listed on the page and was unknown. I did happen to find that the scientist who led the experiments name was Elizabeth Murchison.
The article I read was about a species called Tasmanian devils. Its about a very contagious cancer that grows deep in the Schwann cells central nervous system. The cancer cells spread from animal to animal through bites. The cancer forms on there face near there mouth and eventually gets so large that it covers the mouth and the poor animals die of starvation. So far it has killed seventy percent of the species already and in thirty to fifty years their predicted to be completely extinct.
I really enjoyed the article it provided so much information. It was one of those articles you just wanted to keep on reading. I also really liked the topic it’s not something you see all the time so it really strikes you.
In general it was a really interesting article. Some things that really stood out to me was the way that they die from this terrible cancer. As I said before they die because the cancer is in tumor forms so when it gets large around the mouth it blocks the mouth and stops them from eating, there for they die from starvation. Another thing that really struck me was how fast the whole species can die out and how many have already died. Seventy percent of the species already died out and if they don’t find a cure they will be extinct in 30-50 years.
I don’t really have any questions. All the questions I had in the beginning were answered as I kept on reading. Nothing really confused me and it was a very understandable article.
Don’t Eat That Sandwich
By Jennifer Cutraro
www.sciencenewsforkids.org
This article is about how fast bacteria can contaminate food when dropped. Most people think that if the food is on the ground for less than five seconds it is safe to eat, but scientists proved that wrong. Five seconds is all it takes to become contaminated with bacteria that can make you vomit and have diarrhea.
Bacteria are single celled organisms that can grow on foods. If you manage to eat food with the bacteria on it you will get sick. Salmonella (food borne bacteria) is often found in raw eggs and chicken. In order to kill the bacteria food must be cooked thoroughly. Salmonella can also lurk on household surfaces for weeks and not be visible to the naked eye.
I thought this article was very interesting. I don’t believe in the five second rule and I have never picked food up from floor because I think it is disgusting. But I do know of many kids who use this rule. Now I know that people who go by this rule are ingesting harmful bacteria.
Questions:
1 – Does extreme cold temperature kill bacteria?
2 – Are different foods (different textures) more prone to picking up bacteria? For example, Doritos versus a hamburger bun?
3 - What would happen if you just left the bacteria on the table? Would it eventually die or become stronger?
My article is from http://www.sciencedaily.com/releases/2010/03/100303131652.htm?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+sciencedaily+%28ScienceDaily%3A+Latest+Science+News%29&utm_content=Pageflakes it was called How the Demons of Dementia Possess and Damage Brain Cells
I only got a rough idea of what this article was about because it really confused me. It was about how Alzheimer's effects the certain type of cell that normally protects, repairs, and transfers energy to neurons. This type of cell is called an astrocyte.
I pretty much have no idea what was going on. It confused me on a level I didn't know was possible. It was linked off the blog and I wish they would have used more kid friendly words and ideas. I have lots of questions like why does that happen? And it also said it usually does, what about when it doesn't? Does that happen often? It was pretty interesting actually, what I did retain, I just regret not being able to understand more of it. I guess it was a good article I just don't understand it.
1) I got this article fromhttp://www.sciencenews.org/view/generic/id/56929/title/Researchers_distinguish_two_different_types_of_blood_stem_cells_. It was called RESEARCHERS DISTINGUISH TWO DIFFERENT TYPES OF BLOOD STEM CELLS. It was by Laura Sanders.
2) This artical was about a cell callled a stem cell. This artical says that this is really important because it will make it easier to cure blood diseases. In this artical it said a definition for a stem cell. A stem cell is a kind of cell that if you look at it really closely it gets more complicated. It is also a really important cell because millions of cells die and the stem cell divides it self together, to balance it out. That is really important!
3) A. I really liked this artical because i liked that it had the definition of what a stem cell was. I liked that because i was going to look it up, or ask it as a question but i really liked that i could just read it and know the deffinition. The auther did a good job with that.
B. One thing that really suprised me about this artical is i had no idea how important this cell is. I thought that was really intresting because i had no idea that this cell essential to life. I also thought that it was really intresting that this is usually found in mouses.
C. Some questions that i have about this artical is what other cells are essential? Why is it that it is mostly found in mouse what are so special about mices.
Title: A Maker of Fuel Cells Blooms in California. Author: New York Times. Location: New York Times.
The article was about a man named Todd Woody who made cells that could be used as fuel.
I thought this article was good because it was interesting , short and I understood everything. I was surprise by the fact that a man made a non polluting fuel out of cells. I would want to know how this guy made this.
Labrat liked your review but get something you understand.
RolexJoe thought you did a great reviewing your article.
Summer09 Thought you did a aamazing job it was intresting and well written.
