Largest meat-eating dinosaur discovered

Who: Philip Currie is a scientist, shown in picture, is responsible for the discovery of this new dinosaur with the help of a team of paleontologists

What: Bones have been discovered witch could belong to the largest meat eating dinosaur ever to walk the earth. This dinosaur is said to be bigger and more terrifying than the Tyrannosaurus Rex. It is estimated that this dinosaur lived about 100 million years ago and it is heavier with slightly shorter legs than the T-rex. As seen in the picture, this species had a long, narrow skull and a jaw shaped like scissors. Scientist suggest that it could have dissected its pray with almost surgical precision.

When: Posted on Monday, March 13th, 2000 at 13:50 GMT

Where: These bones were discovered buried in the Patagonian desert, on the eastern slopes of the Argentinean Andes.

Why: This article is a very interesting article. This is something you don’t hear everyday. It is very exciting for everyone when there is such a discovery made. Even though this finding won’t affect our life, it still is very interesting to know what was walking this same earth 100 million years ago. This shows us that no matter how certain we are about everything, something new could be discovered at anytime that brings us to new beliefs.

Outcome: When I look at this article, I just don’t see a report about the discovery of a new dinosaur, I see a message. This article shows that persistence pays off. If you give up , there is never a chance for improvement. Just like the scientist, if they gave up they would have never discovered this species and still to this day would have believed that the T-rex was the biggest and most fear dinosaur.

A tale of two ice caps

Who: NASA is the organization that is named in this article and who is involved in the discovery of the ice caps on Mars. Peter Thomas examines the photos taken

What: This article talks of the disappearance of NASA’s Mars Polar Lander spacecraft last December. But not all hope was lost. The latest pictures sent back from the Global Surveyor spacecraft shows views of the planets polar regions. Mars north and south poles are not very different from the poles here on earth. It contains ice and it expands in the winter and shrinks in the summer. Scientist can tell that the ice caps are composed up of ‘dry ice’ , but it also does contain regular water ice.

When: This was posted on March 9th, 2000

Where: Mars is the planet where these photos are being taken of. The actual place where these photos are being taken is at Cornell University in Ithaca New York.

Why: This article was written to show that all hope hasn’t been given up about the mysteries of the planet Mars. This shows that we can always learn from our mistakes and now later in the future we won’t make the same mistake that could have cost human lives. It also shows that Mars’ poles are somewhat like earths poles and maybe one day there will be a way for life to exist on this planet.

Outcome: I now know that the planet Mars contains ice at its poles. I also know that the poles expand and contract just like earth’s poles. This always leaves that little question in the back of your head….. could life ever excist on the planet Mars???

Drought in U.S. worsening across South, part of Midwest

Who: The U.S. government is the organization who is supplying info. Secretary William Daley also is part of this article.

What: This article talks of the drought that is taking place in the South, part of the Midwest. The hardest hit states are Arizona, Texas, Louisiana, Mississippi, Arkansas, Alabama, Tennessee, Florida, Georgia, Nebraska, Iowa, Illinois and Indiana. Louisiana, Mississippi, and Alabama experienced their driest February in 106 years. Part of the problem is that stream flow east of the Mississippi River are well below normal for this time of the year.

Where: The area’s that are being hit with this drought is Arizona, Texas, Louisiana, Mississippi, Arkansas, Alabama, Tennessee, Florida, Georgia, Nebraska, Iowa, Illinois and Indiana.

Why: This article was written to inform everyone of this event that is taking place in the U.S. This is a serious situation that can’t be taken lightly. Peoples lives could be lost if proper action isn’t taken to prevent tragedies. With the proper steps taken, we can get though this without any one getting hurt.

Outcome: Even though I can’t do anything myself to help there people, I know now of what they are going through. So now everyday I can stop and say alittle pray for them. I can ask God to do what He knows is right. And that decision is something we can’t argue.

Ozone layer ‘thinning over Europe’

Who: Many scientist and meteorologist are involved with this study. One specific scientist is Dr. Johan Hanson. [shown in photo]

What: There is new evidence and worry that the ozone layer is still thinning out over Europe. This has become a new scare because scientist thought this problem was just taking place over the Southern Hemisphere. The ozone layer protect everything on earth from ultraviolet rays. Now that more of these rays are getting into the earth, this leads to a greater chance at developing skin cancer.

When: This article was posted on Friday February 25th, 2000 at 2:46 GMT

Where: This problem was at first only occurring in the Southern Hemisphere. Now as scientist have learned this is taking place in Europe’s region also.

Why: This is, I feel, the most important article I choose to write about. This situation is not something that is going to go away. It is a serious situation and it is something that needs to be taken care of now or 20, 30, or 40 years down the line we are going to be in big trouble.

Outcome: This is a situation I didn’t know was so serious. I have heard about the ozone problem and I never really thought that I could do anything about it, or maybe I just felt that I really didn’t care. But now I see that with this problem I could develop cancer and die. And that is not something I am ready to do. So we have to do something now or there won’t be a tomorrow to worry about.

Concorde driving pigeons off-course?

Who: California Scientist are involved in this growing problem. Also, Jon Hagstrum of the U.S. Geological Survey.

What: The shock waves from the high speed Concorde is said to be believed to throw birds off course and prevent them from hearing a low-frequency sound that helps them navigate to there destination. This problem is said to have about 60,000 birds flying around lost. Without being about to hear these infrasound they are hopeless.

When: This article was posted on March 15th, 2000

Where: This situation is taking place between France and England. This is the place where the Concorde flies through. Research on this is done at a California university.

Why: This article I feel isn’t that big of a deal. Who really cares if the birds get lost???! I know I don’t. Just as long as they don’t get lost and relocate on my front lawn, I could care less where they go. But I really want a good grade on this so I will end this with saying that I hope in the end the birds are happy where ever they end up.

Outcome: I think what I have gained on this article is nothing at all. Come on! This was a whole story about how birds might not be able to fly home because a plane is to loud. All I have to say about that is wow! Find something better to write about!!!!!!
