Biological breakthrough-Dolly the sheep was cloned.

In 1997, the first clone sheep appeared, ewe Dolly, was the first animal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute in Edinburgh, Scotland. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific body part could recreate a whole individual. More specifically, the production of Dolly showed that mature differentiated somatic cells in an adult animal's body could under some circumstances revert back to an undifferentiated pluripotent form and then develop into any part of an animal.

Reflection:
It's really amazing after I read about how did Dolly appeared, I cant believe that Dolly was made by adult somatic cell!!! also she same as Some idea come out of my brain, if Human also can cloned, I believe it will develop of human history, but problems come out, if people cloned success, all around the world only have one kind of people........:) I predict that the world will have more cloned animals because Dolly was a successfull cloned animal, scientist will follow that and they to create another.

Bio Entrepreneurs:Sergey Brin, Larry Page- Google!

Sergey Brin is position of President of Technology at Google, he is the 26th richest person in the world and the 5th richest person in the United States, together with Larry Page. He is also the fourth-youngest billionaire in the world.

Larry Page is an American entrepreneur who created Google with Sergey Brin.

Our Favorite Internet Searching tool: Google!!!

Google is a website that have Internet search, web-based e-mail, online mapping, office productivity, social networking, and video sharing as well as selling advertising-free versions of the same technologies.

On January 1996, Larry Page, who was soon joined by Sergey Brin, two Ph.D. students at Stanford University, California.[6] They hypothesized that a search engine that analyzed the relationships between websites would produce better ranking of results than existing techniques, which ranked results according to the number of times the search term appeared on a page, In August 1996 the initial version of Google was made available.

At now, Google was by far the most popular Web search engine worldwide and most people using that.

Reflection:

It's amazing because Google was created by two Stanford's students! because of google, I can easily to searching website and using E- mail, Im using Goolge everyday, and I enjoy it~ I believe that Goolge would get better in future, If Google has a Friends talking site like MSN or Meebo, people will like it because we can talk to our friend in any time.

Hey Hey Hey!!! My Camera-Eyes

Today, April 17th, guest lecture Dr. Pamela Fong came to Mr. Olson's biology class and explained about different structure of the Eyes. Different areas of the eyes have their own works.

There are some imformation of the eyes structure:

Cornea---- out of the eyes structure, covering the eyes.

Iris---- The colord portion of the eyes, which is opens and closes the monitor amount of lights to get through the eyes.

Lens--- The clear disk to focuses light rays into images, usually Lens are to reflect things.

Retina--- The lining of the eye which contain light-sensitive cells.

Pupil--- is the opening into the center of the eyes.

After this, Dr.Fong showed us different people's the back of the eye balls, it's pretty amazing because they were Dr. Feng's eye balls! I was think about how they put a tiny camera behind of the eyes and captured the pictures, I had a great time to learn about how important of our eyes, If we lose our eyes, all things become chao and dark.

The Dissection:
The second part of the class, Mr. Olson said that we will have a exciting lab, WE HAVE TO CUT OFF THE SHEEP'S EYE! I was feel little scared because that is the first time that I cut off the eye, the skins were so hard because it's protect the inside of the eyes, when we cut off slightly of the eye, many black liquid came out,we saw the lens, sclera and other structure, it's a good experiences to learn about the Eyes, but after the lab, all of my partner are gone and they left the material.........I hope it will not happen in next time. :)

My Own Reflection:
I learned many things about the eyes, also it gives me a attetion to keep my eyes healthy, but i have a question, why we used sheep eyes but not another animal???
However, IT'S A WONDERFUL TIME TO GET EXPERIENCES AND KNOW MORE ABOUT OUR CAMERA.
