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.
