Destiny's hand

That's what everybody else says... I did a better one last time and I got a B. My science teacher's a strict one.

I do them but really just scribble it, so it looks like I do it and than teachers love me :)

here's the report...


Bionics

Bionics: The study of mechanical systems that function like living organisms or parts of living organisms. Bionics are starting to become a part of our everyday lives, not just science fiction. Body parts are being replaced by devices embedded in their nervous systems that respond to commands from their brains. The machines people use are called neural prostheses or- as scientists have become more comfortable with- bionics. I decided to write about this article because when I grow up, I want to become a biomedical engineer, which is in the field of bionics.
Bionics have changed the lives of many people, letting the blind see, the paraplegic walk, and the deaf hear. Scientists have learned that it’s possible to link machine and mind; they have also learned how difficult it is to maintain that connection. Still, bionics represents a big leap forward, enabling researchers to give people back much more of what they lost. The basic technology of prosthetic arms, for example, hasn’t changed much in the last hundred years. A new technique called targeted muscle reinnervation uses nerves remaining after an amputation to control an artificial limb. It was first tried in a patient in 2002. Todd Kuiken, a physician and biomedical engineer at the Rehabilitation Institute of Chicago (RIC), was the person responsible for what the institute had begun calling the “bionic armâ€.
The most interesting thing I learned from this article was that researchers are pushing the neural prosthetic concept even further. They are beginning to use it on the brain itself. Scientists are behind a project called “Brain Gateâ€. They are attempting to wire the motor cortex of completely immobilized patients directly into a computer so that patients can move remote objects with their minds. So far, test subjects have been able to move a cursor around a computer screen. Researchers are even planning to develop an artificial hippocampus, the part of the brain that stores memories, with the intent of implanting it in people with memory loss. I thought it was interesting because people with Alzheimer’s will be able to retain memory longer than before they had the artificial implant.
Bionics is a term that was originally applied to a variety of scientific projects involving biological systems, engineering systems and artificial intelligence. Since the mid 70’s, the use of the term “bionics†has become popular among the general public to describe work on artificial organs and related medical devices. Bionic devices serve different purposes. Some replace body parts that are missing due to injury, diseases, or birth defects. Other bionic devices help body parts that do not work properly. In the future, people may use bionic devices to improve healthy bodies. Some of the most popular bionic devices have been designed by the people who use them. For example, Mr. Van Phillips designed his own prosthetic leg because he didn’t like any of the available replacements. It’s designed for mountain climbers and for bike riders. He is also working on an adaptable foot that would allow people to jog one minute and play golf the next. Biomedical engineering is a branch of engineering that applies engineering knowledge to solve problems in biology and medicine. Biomedical engineers are health-care professionals, like doctors, nurses, and medical technicians. Some of these engineers help diagnose and treat human disorders. Other do research, design medical instruments, or work with doctors to develop more technologically advanced medical procedures. It has been done by the robotic invention called the Da Vinci Robot that enables surgeries at a distance (telesurgery). The instrument can rotate 360° while the human hand can only rotate 180°. It completely eliminates the natural tremor of the surgeon’s hands. There are a number of well –established areas in biomedical engineering: Bioinstrumentation, Biomechanics, Biomaterials, Systems physiology, Clinical engineering, and Rehabilitation engineering.
I came to the conclusion that for centuries, people have dreamed of repairing and improving their bodies with bionic inventions. Some of their wildest dreams have become reality. Science fiction concepts are rapidly becoming a reality. This growing technology continues to change the way we think, not just about computers, but about the nature of life itself.

oh, and check this out...

Not much. I just finished a report on bionics. Wanna read it?

wow. that really specific.

since when have you been back?

I know I hate homework too :P

sorry, i didn't mean to be offensive. WOW.

PS: I hope it's not Pizza Hut.

no. *gets pen and paper ready* Shoot.

it's been a random day... remember when i told you my gf broke up with me? her best friend asked me out today (it's Valentine's Day, duh!), and i said yes. sooo......

*gives thumbs up* good for you! oh, and this guy is my uncle.

Boring homework :)

That's Awesome! what's up ? :)

hey now read it

I hate you

Hurry and do It!!!!!!!!!!!!

Ok...... Hey go look at my poem " Where I'm from!"

how does it need me?

Oh thank god!!!!!!!!!!!!!!!!!!!!11
I didnt want to be the only one!!
No Homo, but anna looked really cute
