2,700 year old fabric.

Have you ever heard of a piece of fabric that was older than 2,000 years old? In Athens, Greece, archaeologists found a piece of fabric that was 2,700 years old! The material was in a copper urn. Besides the fabric inside the urn, archaeologists also found dried pomegranates. This old antique was found in a burial they think imitated the cremation of soldiers described in Homer's "Iliad."

Interesting facts that I learned was:

1) The fabric found in the urn was an organic material and easily decomposable.

2) The pomergrates, that were also found inside the urn, were offerings that linked with the ancient gods of the underworld.

3) Only a few artifacts, similar, have beein found in Greece.

In my opinion, this is extremely fasinating that several artifacts have been found from a long period ago and are shown in museums for us to see.

Tainted food.

In Washington, the government reported Thursday, that several hundred of the 6,000 hogs have eaten tainted feed. The risk of human health may be very low. The government told three states that were involved, that the meat wasn't allowed to be sold from the hogs that had eaten the feed. The Agriculture Department concluded that the three states, New York, California and South Carolina, had no more than 345 hogs that ate the food. Most of the hogs that ate the feed are still on the farms that they were raised.

Three interesting facts that I learned were:

1) Some food could not be sold so they were fed to the hog farms.

2) Since mid-March, pet food companies have had more than 100 brands of dog and cat food and treats that were tainted.

3) The pet food sent to the farms was discovered to have an ingredient, rice protein concentrate, imported from China that was tainted by an industrial chemical, melamine.

I think that food shouldn't be given to farm animals if it isn't sold in the store. Then if people eat the meat from the animal, humans will become sick or will die.

Largest coral die-off

You may hear of people being killed from natural causes, but this earthquake, which happened two years ago, in Jakarta, Indonesia caused the largest coral die-off ever documented. The scientists from the U.S.-based Wildlife Conservation Society and the government-backed Australian Research Council Center of Excellence for Coral Reef Studies, studied the product of the earthquake. Because of this earthquake, it caused the corals to have the largest die-off ever documented.

This problem can relate to science and life because the earthquake caused several people to die and the largest coral die-off.

In my opinion, the earthquake caused countless people to die and also caused the largest coral die-off. Even tough most of the coral had died, the scientist concluded that the coral would eventually grow back in several years to come. Because of this natural disaster, it took away the lives of several people, but the people in Indonesia couldn’t have predicted or done anything to help other’s death.

The Sun

You may think that the sun is a small part of our lives, but you are wrong. The sun is has an enormous impact in our habitat. Not only is this giant star used for heat, it is also used to keep all the organisms on the Earth alive. With the sun giving off so much energy, it helps to grow food for all living creatures on the planet.

Three interesting facts that I learned are:

1) The sun has a spectral glass of G2V. "G2" means that it has a surface temperature of approximately 5,500 K, giving it a white color, which causes the sun to appear yellow.

2) The sun completes one revolution in about 225-250 million years.

3) The Sun is about 4.5 billion years old. Since its birth it has used up about half of the hydrogen in its core. It will "live" for about another 5 billion years.

I think that the sun is the most important object for the Earth. It helps the organsims on the planet to get food and other supplies that help them stay alive. I also believe that this giant star can harm the Earth.

Meiosis

Meiosis is the process of cell division where sex cells are produced, also when chromosomes split and form sex cells in the end. The male sex cell is called sperm and the female sex cell is called an egg. This division occurs in all eukaryotes. There are three basic steps:
1) the chromosome doubles
2) the 1st division
3) the 2nd division

Here’s an example of meiosis. A human body cell has 46 chromosomes. Female:

46

92

/ \

46 46

/ \ / \

23 23 23 23

I \ I /

1 egg & 3 polar bodies

or

\ I I /

4 sperm

Interesting facts that I learned were:

1) There are four stages in a nuclear division: prophase, metaphase, anaphase, and telophase.
2) Meiosis comes from the Greek work meioun, which means “to make smaller.”
3) Some eukaryotes lost the ability to carry out meiosis and got the ability to reproduce by parthenogensis.

In my opinion, I think that meiosis is an important part of life. Without the process of meiosis, any living organism wouldn't be able to reproduce. If our parents didn't reproduce, we all wouldn't be here today.

Cells

Cells. Such a tiny word can mean so much. A cell is the basic unit of life. Every single living organism has cells. Cells are everywhere, because they are microscopic. There are unicellular and multicellular organisms. Organisms that are unicellular, for example, are bacteria, yeasts, and amoebas. Other multicellular organisms are plants, animals, and humans.

Interesting facts that I learned from these articles are:

1) It takes millions of cells to make up the skin on the palm of your hand.

2) Animals have a skeleton because of a unique structure, the cell wall, which is why plants droop.

3) The human body has over ten trillion cells. (10,000,000,000,000)

In my opinion, I think that cells are the most important subject in science and life. Every living organism has cells, which I think, is extremely interesting. There would be no life if there weren’t any cells. Cells make everything come to life because it is the basic unit of life. If it weren’t for cells, we wouldn’t have most of the supplies we need today.

Europe's first stegosaurus was discovered.

What dinosaur do you know of that is an herbivore, 20 feet long and is studded with spikes on its tail? If you guessed a stegosaurus, you are correct. After the Jurassic period ended, about 150 million years ago, all dinosaurs became extinct. Because of this, there are fossils from these dinosaurs. Europe found their first stegosaurus fossil. Dinosaur fossils are usually found in North America, but not commonly in other continents. Surprisingly this happened. When the continents were still connected, Pangaea, dinosaurs would cross land bridges to other parts of land, which in this case is now known as Europe.

I think that this extremely fascinating to find fossils in other continents. Before reading this article, I thought that dinosaurs fossils were only found in North America and not in other coninents.

Finding dinosaur fossils can relate to science because when you discover something new you want to research about it and know more about it. By resarching about the fossil it can tell you what kind of dinosaur it cane from and learn more about that dinosaur. This can also relate to life because dinosaurs were once living, just like humans, but then became extinct.
