Summary: The article was talking about how membrane fusion is an important step for the passing of items between two cells. The article said membrane fusion is how HIV infect cells. So Membrane fusion is important because of what it can pass on to you.
Questions: Which components of the cell membrane are being discussed in the article? The whole cell membrane itself.
What is the purpose of the process or component in the article. The proces is important because it is the cause of you having HIV and other diseases or isn't.
List three things you learned from the article in your own words. That HIV is passed during this process, that the membrane allows deadly items into your cells sometimes, and that the process in the article is called membrane fusion.
What impact would the absence of this organelle/process have on the cell? the cell would be unprotected from outside diseases and invaders. The cell would eventually die.

http://www.sciencedaily.com/releases/2007/07/070725143612.htm
Summary: The article was talking about how global warming is being spead up by the rising surface ozone. As a result of this crop yeilds and plants are being killed. Since plant soil hold one- fourth of human carbon dioxide without them global warming is just spead up. Eventually there will be to much carbon - dioxide.
Questions: What are some ways this phenomenon could be stopped? stop burning forests and fossil fuels.
Is there anything you could do to contribute to the reversal. Plant more trees and start conservation groups.
List three things you learned from this article in your own words. That global warming is being spead up, that more and more carbon dioxide is filling the air, and that we should get conservation efforts going before we have a huge problem.
What impact would the continuance of these process have on the biosphere? it could change it into a non-resourcable planet with no life.

Handsome By Chance: Why Humans Look Different From Neanderthals
http://www.sciencedaily.com/releases/2007/08/070813101018.htm
Summary: The article is talking about how neanderthals and humans skulls are very different. However they don't believe it is natural selection. They believe that random changes occured because of the isolation between the two.
Questions: How is natural selection or evolution illustrated in this article? The article is comparing neanderthals skull with a human skull.
How does this support Darwin original findings? Yes
List three things you learned from this article in your own words. That the differences occured because of isolation, also that these two species have been isolated for a while, and that our late relatives have nothing in common with us.
What impact would the absence of this organism have on the ecosystem? it would basically create a new ecosystem because a whole species would be gone.

Describe the niche being discussed in the article. Living in ice and feeding on whatever is available.
List three things you learned from this article in your own words. The ice-caps are melting, that animals will suffer if they continue to melt, and that certain organisms have certain niches.

Giant Panda Can Survive
http://www.sciencedaily.com/releases/2007/08/070824104831.htm
Summary: The article was saying that genetic development is not the cause of Panda decline. Instead scientists believe in fact that humans are the cause. Scientists believe that human activities are the main reason for the decline. The Panda's habitats are being desroyed so they can't reproduce well because they have not adapted to the new habitats.
Questions: Why is this species endangered? The Panda is endangered because of deforestation and poaching.
What could prevent this organism from going extinct? New conservation efforts
List three things you learned from this article in your own words. Humans are hurting the panda populations, more and more panda's are being hunted, and without conservation efforts the Panda's could end up being in some major trouble.
What impact would the absence of this organism have on its ecosystem/community? The bamboo habitats will eventually overrun other habitats and hurt even more of the ecosystem.

HIV-infected Infants Respond Poorly To Childhood Vaccination
http://www.sciencedaily.com/releases/2007/12/071205095404.htm
Summary: The article was talking about how kids with HIV don't recieve appropriate levels of drugs they become immune depressed. The study that was held showed how kids with HIV are more exceptable to getting other diseases. Measles is a major disease where antibodies can't heavily guard because of the low levels. So overall the topic was that kids are not responding well to the medicine and that scientist need to find out what is going wrong so they can fix it.
Questions: What are the symptoms of this disease? HIV affects the immune system and completely shuts it down
How is this disease passed from person to person? Sexual contact, and blood transfusion
List three things you learned from this article in your own words. That kids are having a hard time since they are affected, that kids are more exceptible to drugs if they have HIV, and That scientists have a tough job ahead of them to find the cure for this problem.
What impact does this disease have on the US economy? It has non-profitable organizations helping out to find a cure. Also some of the economy money goes toward reasearch efforts.

Radiation-eating' Fungi Finding Could Trigger Recalution of Earth's Energy Balance and Help Feed Astraunots
Link: http://www.sciencedaily.com/releases/2007/05/070522210932.htm
Summary: This story was talking about how with fungi living off radiation that it could help do things that seem hard. Since these fungi eat radiation they help balance the earth's energy. Scientists found out that there are two types fungi that do this. One was induced to make melanin and the other naturally contains it. Last, melanin in fungi is no different to melanin in our skin.
Fungi Article Questions:
1) What type of lifestyle does the fungus in the article have? (Is it saprophytic, autotrophic, or parasitic?) What information lead you to this conclusion? saphrophytic, it does not use the sun for food or live in intestines of any living thing.
2) What benefits or problems can you foresee with this particular fungus? a benefit would be not having to worry about getting astranauts food and one problem would be radiation poisoning.
3) List three things you learned from this article in your own words. Fungi can eat radiation, these fungi are actually studied, and radiation used in fungi can actually be helpful.
4) Infer what potential impact this fungus will have on the environment it grows in? ending up having a radiation overflow which could hurt any living things near it.
