Professor James Friend and his crew at Monash University have been researching and trying to miniaturize the tubes to look into patients body during surgery. Even in smaller operations, damage has been done because of the over sized tube that are being moved around in the body. It could sometimes cut and artery or blood vessel. They needed to find a way to fix that problem. They have been looking for an answer for the past two years. Professor Friend used
piezoelectricity, the energy used for stoves, in extremely small mechanical robots to swim around in the blood. This is an easy way to look at the problem in the body with out more damage done. I think that the scientific age is growing at a rapid pace. Miniaturizing objects is a very smart thing to do. It says in the article it could probably even reach the brain area with these small robots. I am shocked and intrigued by how by just making an object smaller it could have many benefits.

An important event in history has recently occurred. Yes, the inauguration for the 44Th president has occurred. But, what is a great part of this is that President Barrack Hussein Obama is the first black president in the United States. Many years ago people thought a black president was impossible. Now to actually see it happen, resurrects the souls of many and even kids know they can be what ever they want to be when there older. I think that this whole event is amazing. I can be able to tell my kids how i witnessed what had happend. A black man is president. Breaking the barrior of what can be done.

“Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America,” Some thought as heroic words, but this inspirational sentence shows the start of a new nation. One that is more united and that will have to work a little to be the best country we can. One part in article number one it is telling how there was some struggle at when Obama was being sworn in. Jusitce Roberts messed up with the words slightly. So it was a little wierd. But after that it all went smooth. There was so many people who went to the swearing in. It was loud and filled with emotions. There was much police at the event to prevent an accedent.

"first black leader as millions watched from the National Mall and around the world." This quote was saying that many people from around the world watched this important event. Especially since America might be on the brink of a world war III. But Obama is there to insure the saftey of our country and expedite the process of recovering the economy. We trust him and expect Barrack to do good. He has already started to fit in to the White House and got to work in Guantonomo Bay.

Can rocks move? Well on mars small rocks called clasts seem to move a lot. Scientist were stunned by this phenomenon. Jon Pelletier a geologist has been trying to find out how these scattered clasts "move". It seemed to be that the wind blew the rocks forward. But since the planet mars has a skinny atmosphere that would be harder to do. So what scientist found out was that the rocks go through a system called the "tidy arrangement". What scientist think what happens is that the wind from the windy planet picks up sand from the planet and places it behind the rock. Making small dunes behind the rock. Which also creates a hole in front of the rock. So as long as the wind keeps blowing in Mars the clasts will keep moving.

In class we were working on food webs and food chains. A food chain follows a path which animals find food. A food web shows how plants and animals are connected and shows the organisms that give energy to each other. An easy way to think of foodwebs and food chains is that its energy that flows through an ecosystem. I like how food chains work becuase it is a simple organized way to understand the balance in the prey vs. predator cycle. For example a food chain could be: Hawk(eats)Snake(who eats)Rat(who eats) Grass hopper.

Symbiosis Project

These clear pictures that show parasitism were taken in the woods in Kendall Park, New Jersey. The difference between symbiotic relationships is small but very large. In these photos it shows parasitism between fungi and a tree stump. Parasitism is a symbiotic relationship which two organisms interact while one is benefiting and one is being harmed. The fungus in this picture is the parasite and the tree stump is the host. The mushroom is decomposing and harming the tree stump. Parasitism is important in nature because it helps balance out the food web in an ecosystem. Most parasites are small but do much damage to their host. For example, without parasites there would be a big quantity of one species because the parasites usually tend to go for the bigger hosts. So it’s a chain reaction. A parasite varrys in sizes from very small to pretty big. Some parasites you cannot even see! Then some are feet long. I think parasitism is a different way of living but something that must be done. Parasitism is an easy way for them to live. Since there is little competition and it sustains the food chain I accept this symbiosis in my life. It is hard to avoid parasitism in the world so you must allow what happends. Not every thing can change.

A super tomato? That's crazy. In London on October 26Th scientists discovered from research that a tomato was changed and made with the nutrients usually in dark berries. With that nutrients this tomato changed to purple in the process. The tomato may possibly fight cancer in mice. Mice that were genetically changed to get cancer and ate the tomato lived an average of 40 days longer than those mice who didn't. Scientist are happy because this information can lead to bigger and better things, maybe even food that can fight cancer for humans. I agree and am happy with this research scientist are doing. I think that genetically changing tomato's or food is brilliant because just from eating we can become healthier.

Imagine a planet that is a giant firey gas ball almost twice the size of jupiter. This planet is named WASP-12b and has been discovered by scientist recently. This planet is atleast 4,000 degrees and orbits its own star quicker than any other planet we know in todays scientific knowledge. WASP-12b orbits its star every single day. Wow! I think that is amazing. It just makes you think that you never know what new and exiting things can appear They used a new program called the SuperWASP project to find the WASP-12b. The project measured the the difference in light when its blocked by its parent star and when it was not. The WASP-12b is located 870 light years away from earth or 5114009186351706 Miles. As all this might be exiting now I think that greater and more interesting are to come.
