  This thing was so hard to do! But in the end, I had fun with it.

  Mit has made optics on a chip, a new advancement in nanotechnology and communication. The new streamlined chip combines imaging with fiber optics, and combined with other technology such as coding, writing and faster processers, information can move from place to place at a speed almost not imaginable to land lines and copper wire. The new device will allow computers to have better links with internet services and sites and help scientists conduct remote testing and spectroscopy. Those kinds of options would be great news for probes on Europa or other spacecraft the chips will be introduced onto the mass-market production lines within five years if demand is large enough. I think that the author of the article was way to short, and the author could have spent more time adding more details to the article.

  I think that the advantages of having an unusually large brain size for our body is that we have a lot more processing power. Some animals, example cats, have a brain the size of a walnut, and look how advanced they are. I think that we developed a larger brain because as we evolved different skills to survive, like speech to coordinate hunts and information, and inventiveness to make new weapons, home designs, and other things that would protect us and help us live our brain had to create more space. Some of the skills and advantages that came with it are stated as follows. We can speak, we have the ability to eat different food, and we can have extremely complex thought processes, and have individual personalities. We also communicate with complex verbal skills, have the ability to advance and better ourselves, and also have an understanding of time and space. Included are the skills of invention, art, and emotions. The bad parts of our large cranium are that we create technology that pollutes, damages, and generally destroys the space around us. What I find unusual about our brain is that even when we use every one of our brain functions, we only utilize 17 percent of it. That means that 83 percent of our brain is never used, and is just empty space. Scientists have no idea of what or why that space is there, so there are some things we don’t know. Those are the advantages of a big brain.

  Tumor killing virus

  Source was http://www.sciencedaily.com/

  In the UK, a team of scientists and doctors have been performing injections that supposedly can eliminate brain cancer. An injection containing a mutant herpes virus was given to a man with brain cancer in 1997. The man had 4 months to live, but after the injection he is still alive with no tumor. Doctors had the idea of using a mutated virus after a report from 1912 that a woman had been bitten by a dog, and when doctors gave here a dose of weak rabies vaccine, her cancer tumor shrank. So researchers genetically mutated a herpes virus so it only attacked cancer cells and not the human body. Doctors that used the drug on patients reported that patients lived up to eight or ten years when they were only supposed to live a few moths. Some patients are now living normal life. Viruses seem to be the best defense against cancer. You can alter them to infiltrate the cancer cell and implode it, make it commit suicide, and can kill them in thousands of other ways. They are so effective that they kill up to 4000 cancer cells per single cancer cell, compared to the 14:1 ratio of chemotherapy. I think that this weapon shows a great potential for becoming an effective cure, and I hope that more people get to use it. I think that the author of this study did a great job of explaining this new technology.
