Advance Made In Search For Genes Associated With Colon Cancer

Link:http://www.sciencedaily.com/releases/2007/07/070708173046.htm

Colon Cancer is one of those diseases that are passed down genetically. Perhaps not through every generations, but it really shows up in people whose family has a history of colon cancer. That's how you can link the two.

Genetic Engineering
What process is being used in the article?primordial soup
What is the purpose of genetic engineering in this article? to make a genetic discovery
List three things you learned from this article in your own words.I learned that colon cancer is genetic, I learned that there are alot of discoveries in this area, finally, I learned that you can use several methods to find the specific gene.
What impact would the absence of this process have on humanity?we wouldn't know much abou these diseases.

Scientists Offer New View Of Photosynthesis

Link:http://www.sciencedaily.com/releases/2007/05/070503140651.htm

Photosynthesis is a process by which plants convert carbon dioxide into energy and sugar using sunlight. This puts oxygen back into the atmosphere for us to breathe. They've used this process ever since the dawn of time when plants first emerged.


Photosynthesis
What is the chemical equation for photosynthesis?6 H2O + 6 CO2 = C 6H12 O6 + 6O2
What organelles are involved in this process?leaves , chlorolplasts
List three things you learned from this article in your own words.Photosynthesis is a process for plants to gain energy, they use sunlight, and all plants use it.
What impact would the absence of this process have on the biosphere?oxygen wouldn't be recycled and put back into the atmosphere.

'Wiring Up' Enzymes For Producing Hydrogen In Fuel Cells

Link:http://www.sciencedaily.com/releases/2007/11/071119100338.htm

Scientists report a successful test of hydrogen fuel. They used enzymes to produce an electrical connection between a carbon nanotube and a hydrogenase. This could produce electrical fuel for the future. But, this is still being tested in order to work out some difficulties.

Enzymes
What reactions does this enzyme catalyze?a carbon nanotube and a hydrogenase
How is the cell affected if this enzyme is removed?doesn't work
List three things you learned from this article in your own words.there are difficulties, this could be used as fuel, they are still testing.
What impact would the absence of this molecule have on the cell?wouldn't work

First Comprehensive Study Of Proteins Inside A Single Type Of Cell

Link:http://www.sciencedaily.com/search/?type=news&keyword=Proteins&section=all&period=all

Proteins are found everywhere. In the survey where scientists counted the number of proteins on a Jurkat T cell, 6400 proteins were found. This will help us better understand the protein society.

Organic Molecules
What is the major role of this molecule in the cell?gives energy
List three things you learned from this article in your own words.This was the first large scaled survey of proteins, Jurkat T cells are Leukemia cells, the head scientist's name was David K. Han.
What impact would the absence of this molecule have on the cell?wouldn't have much energy.

Experts Outline Recommendations For Treating Malaria In The US

Link:http://www.sciencedaily.com/releases/2007/05/070522162650.htm

Malaria is a deadly disease spread by mosquitoes. It causes at least one million deaths per year. It happens mainly in the tropics and subtropics. Scientists are still working on a cure.


Human Disease
What are the symptoms of this disease?high fever, nausea, dizzyness
How is this disease passed from person to person?mosquitoes
List three things you learned from this article in your own words.Malaria is now dangerous to pregnant mothers, it happens in tropics and subtropics, it has no cure
What impact does this disease have on the US economy?helps it because of people trying to get away from it

Giant pandas under threat from parasitic worm

Link:http://environment.newscientist.com/article/dn13016-giant-pandas-under-threat-from-parasitic-worm.html

Pandas are under threat from a parasitic worm. This worm is the greatest cause of death to these pandas. Pandas are under a lot of pressure and could go extinct. They might not make it.

Endangered species
Why is this species endangered? Parasitic worms
What could prevent this organism from going extinct? protection
List three things you learned from this article in your own words. pandas are endangered, they might die out, they need protection.
What impact would the absence of this organism have on its ecosystem/community? out of control popullation of panda's food

Gregor Mendel

Link:http://www.sciencedaily.com/articles/g/gregor_mendel.htm

Gregor Mendel was very dedicated to his work. He was a monk but on his spare time he worked with plants which led him to genetics. Today he is called the father of genetics. He studied the inheretance of traits in plants.

Mendel and Genetics
Explain the phenomenon being described in the article.talks about Gregor Mendel
What is the difference between a genotype and a phenotype?geno is letters, pheno is looks
List three things you learned from this article in your own words.Gregor was a monk, he loved plants, he was dedicated to his work
What impact would the not understanding genetics have on medicine or agriculture?we wouldn't know our blood types, we wouldn't know how to cure the flu and other diseases or viruses

Present-day Species Of Piranha Resulted From Marine Incursion Into Amazon Basin

Link:http://www.sciencedaily.com/releases/2007/12/071203131505.htm

Natural Selection works in wierd ways. It changes an animal according to their environment, what they eat, and what dangers they face. The piranha was changed according to their environment. They changed in order to survive.

Natural selection/Evolution
How is natural selection or evolution illustrated in this article?the piranha was changed to live in its environment
How does this support Darwin's original findings?it matches it
List three things you learned from this article in your own words.piranhas didn't always live in South America, they weren't always the same, they changed their DNA
What impact would the absence of this organism have on the ecosystem?the rivers of South America ould be polluted with dead bodies

The Nucleus: Not Just A Bag Of Chromosomes

Link:http://www.sciencedaily.com/releases/2003/02/030217114712.htm

Cell Organelles are what keep the cell functioning. They control functions vital for the cell's survival. They keep your cell moving. Organnelles would include: nuecleus, ER, Golgi Apparatus, ribosome, chlorolplast, and more! I'm now going to answer questions about the nucleus.

Cell Organelles
What is the major function of this cell's organelle?controls the cells
Which cell types have this organelle?all
List three things you learned from this article in your own words.Nucleus is important to cell, it controls it, it is the brain
What impact would the absence of this organelle have on the cell?cells would die
