3/ Summary:

The article discusses a new diagnostic tool that could diagnose people's diseases in a simple way while they are at home. The article begins to discuss the two students who invented this tool, Gaster and Hall from Stanford University. This small tool diagnoses diseases from Flu to Human Immunodeficiency Virus by identifying the proteins of diseases and without doctors. The reason for inventing this tool is to use it in airports to reduce the spread of some diseases and for developing countries that usually do not have enapght doctors or even in poor countries. Gaster and Hall won and received many prizes in ceremonies in Los Angeles and New York. After that, the article discusses how Gaster and Hall planned to invent this tool and how much time they spent on it. Then, the article discusses how this tool works and what the advantages of it.



4/ Reaction:

I find the article discusses a perfect tool that help people in many ways. For example, according to the article this tool digneoses many diseases beginning with Flu and including Human Immunodeficiency Virus. The intresting infromation about this tool that is people can use it where ever they are and it does not require laboraries or doctors. Now, in my country swine Flu (H1F1) is a serious disease ; many people, if they feel that they have the Flu, immediately they go to hospitals to check their health. It is true, but sometimes it is dengoris to go to hospitals because there are possible ways to receive this disease from other patients. On the other hand, if you have this tool in your home you can check your health in any time you want and in a safe place. In addition, it is a useful tool in airports to reduce the spread of pandemics. To look at some poor countries which have a shortage of doctors and in the medical instruments or labotaries, we will find this tool could solve these problems in simple ways. Moreover, it will help people in developing countries which have crowded hospitals. Furthermore, the simple way of using this tool makes it a unique tool in the medical field. Also, this tool is not used just for dignosing diseases, but it also could used as a positive or negative pregnancy test. At the end, I find this tool could help and solve many problems in our countries, so we should encourage doctors in different countries to develop and support this tool to make it as a useful tool in the medical field.

3/ Summary:

The artical discusses new invention which would be a good solution for people who lost limbs or paralysis. The articale begins with the story of kitts, who lost her left arm in a car accident, and of this new invention (artificial arm). This invention can help peopl who have lost their hands to move their wrist and elbow all at the same time. In addition, the author explines the relationship between the nerves and brains, and how they could move missing limbs in people's bodies. Also, many researchers mention this invention could effecailly solve a lot of problems in the medical field. Some sergories in this field were preformed for 30 people in the United States, Canada and Europe, including eight soldiers injured in wars. There were five patients who preformed an experiment to do ten differnt movements bu using virtual arms. These movements were not as perfect as for the able-bodied Finally, research will continue to make a normal functioning of people's missing limbs.

4/ Reaction:

I find that artical discusses important research about the connction between nerves and brains. The intresting thing in this artical is how we can combine between two different scinces to solve serious problems. For example, in this artical we can infer that we have two different scinces: Engineering, which is in this artical resbonsible for the artficail arm, and the medical field, whose function to connect the artifcail arm to the brain. In addition, this search could solve alot of problems related to disabled people like missing limbs and paralysis. In my country, there are a lot people who are injured by accidents and who thier limbs or can not even move because of paralysis. Furthermore, I find another beatiful part of this search about electrical signals could help some desaises like hight blood prssuere and dibetes.diseases like these which depand on the controling can be solved with electrical signals. I find also, it is a good begining for this invention esspcailly to do ten different movemensts. Tepiecally these movements as not like able people's movements, but it is possible to develop this invention or search until the time they can make them as natural movements. As a result, many people can do their activties in perfect ways. I know one friend who had a good position in his work but he had to quite after having an accident and losing his left hand. My point is this search can help disabiled people to have good lives no matter what kinds of injuries they have.
