Cool this will allow me to use Ebon Blade Banner, Darkmender's Tincture, Hodir's Horn, Essence of Ice, and Raelorasz's Spear, 2 nano seconds quicker than the other n00bs. LEEEEROY!!!111!!!

oh yeh and please use the correct tags.

sir you got every single thing right there. It's scary.

issues about iPhone

good article highlighting iphone 4 problems. be careful to keep articles up to date. This one is over a year old.

issues about iPhone

Good article Jorge F1. Maybe better to use the original article. http://www.bbc.co.uk/news/technology-12121999 The Red Ring of Death has been responsible for a lot of upset gamers in the past....

Criterion B . Describe, step by step, how the IT system works. 1. Surgically implanted nerves are connected to electrodes placed on the chest area. 2.The nerves prompt electrical signals from the brain to the electrodes. 3. The electrical signals are then interpreted by a micro-processor, into natural movements. More information on how bionic arms work: http://thetartan.org/2008/9/22/scitech/howthingswork

Outline how this IT system works: Essentially, this system consists of hardware (electrodes) that replace the nerves going to and from the brain. Electrodes are connected to the chest muscles which control 6 motors that move the prosthetic joints. When the mind sends a message through the nerves to move a muscle in the arm, the signal causes a muscle in the chest to contract, which activates a certain electrode to tell a motor to move a part of the bionic arm. A more detailed account of how mind-controlled bionics works is here: http://science.howstuffworks.com/bionic-arm.htm This story is a prime example of how IT is being used to radically develop medical research and treatments.

The main social and ethical issue in this article is People and Machines. This new bionic arm which is controlled by the mind is an important development, in this technology, now allowing people who have had to have limbs amputated to have new arms/legs that they can control as they would their original arms/legs. However, due to the fact that it is very new and expensive technology to develop, although it points to the future, at the moment almost no one that would need a bioninc arm would be able to afford it. This means that although it is an essential step forward, at the moment it will not be something that can help the majority of people who most need it. As well as this, the bionic arm, although it is controlled by the mind, it will never be as fluid and will never work as intuitively as your arm.
