http://www.newscientist.com/article/mg15220596.000-review--mendel-and-the-mixed-up-moggie.html
Summary: Laura Gould brings home a calico cat named George. George should be female, because everyone knows that only females can be calicos. Even a glance at George's body shaows that he is all male. This unusual discovery her on a search for the genetic anomaly that created her mixed-up moggi.
Explain the phenomenon being described in the article. A cat that is suppose to be a female looks like a male
What is the difference between a genotype and a phenotype? A genotype is the letters, the phenotype is the appearance
List three things you learned from this article in your own words.
1.) Calico cats are all female.
2.) Calico's are red, black, or white
3.) Mendel made a mistake with his experiment
What impact would the not understanding genetics have on medicine or agriculture? you wouldnt be able to know how to make medicines and cure people

How planet Earth turned green
http://environment.newscientist.com/channel/earth/mg19225804.800-how-planet-earth-turned-green.html
Summary: Earth was covered in thick sheets of ice 2.3 billion years ago. Earth thawed and it released strong oxidants into the oceans and atmosphere for the first time. This set off a chain of events that led to oxygen-tolerant marine organisms and photosynthesis as we know it today.
What is the chemical equation for photosynthesis? CO2 + 2H2O >> CH2O + O2 + H2O.
What organelles are involved in this process? The chloroplast
List three things you learned from this article in your own words.
1.) The Earth was once covered in ice.
2.) Oxygen was once deadly on earth.
3.) Oxygenic photosynthesis involves freeing electrons from water which takes more energy and produces oxygen.
What impact would the absence of this process have on the biosphere? we would be able to survive

Genetic Engineering
http://www.newscientist.com/article/dn10533-genetic-engineering.html
Summary: Workers took eggs containing fruit-fly embryos in different stages of early development. Then they soaked them in DNA. In these experiments, the DNA was kept from other flies that were different in a lot of ways from those providing the eggs. The difference involved ten or eleven genes on different places on the chromosomes.
What process is being used in the article? Taking eggs from fruit-flies and soaking them in DNA
What is the purpose of genetic engineering in this article? To change the structure, the color of the bristles, wing veins, wing structure, and eye color
List three things you learned from this article in your own words.
1.) Genetic engineering changes your features.
2.) DNA occurs in the genes of chromosomes.
3.) It is not to soon to figure out how much genetic engineering is applied to man.

New Way To Identify, Evolve Novel Enzymes
http://www.sciencedaily.com/releases/2007/08/070815135116.htm
Summary: Enzymes are specialized molecules that accelerate chemical reactions between molecules. Proteins and other chemicals that underlies biological activities need the help of enzymes. The development of new enzymes can help improve chemicals, and develop new therapies. The new way of creating enzymes does not require understanding of how the enzymes work.
What reactions does this enzyme catalyze? It makes a chemical reaction
How is the cell affected if this enzyme is removed? It slows down the chemical reactions
List three things you learned from this article in your own words.
1.) The creation of totally new enzymes can develop new therapies.
2.) Creating enzymes does not require knowing how the enzyme work.
3.) Enzymes can help improve the chemicals.

HIV-TB Spreads In Africa, Undermines Control Of World's Two Deadliest Infectious Diseases
http://www.sciencedaily.com/releases/2007/11/071102084827.htm
Summary: The world-wide epidemics HIV and tuberculosis has combined to create a deadly co-epidemic that is spreading quickly in sub-Saharan Africa. Health systems cannot diagnose, treat, or contain the co-epidemic because of unanswered medical questions. One-third of the world's 40 million people with HIV/AIDS are also infected with TB.
What are the symptoms of this disease?Respiratory Problems, Lung Disease
How is this disease passed from person to person? coughing
List three things you learned from this article in your own words.
1.) South Africa is the only country in sub-Saharan Africa with a to diagnose TB.
2.) TB has dropped slightly but is still high at approximately 85 percent.
3.) The HIV epidemic has destabilized TB in regions with high rates of HIV.
What impact does this disease have on the US economy? Many people in sub-Saharan Africa are infected with it and are dying.

List three things you learned from this article in your own words.
1.) Young trees play an important role in removing carbon dioxide
2.)This can temporarily reduce photosynthesis
3.) All the dead wood will be consumed by decomposers and this will result in a large carbon release
