Stem cells have the ability to develop into different types of cells, such as muscle, blood, and brain tissue Potential uses include: alternative to organ transplant, safe drug testing, and finding alternative methods to fight disease such as cancer and diabetes
First successful permanent artificial heart, implemented in 1982 The natural heart is removed and replaced with the mechanical Jarvik-7 heart Highest success rate of any mechanical heart or assist device
Creating a genetic twin 1997, “Dolly” the first cloned sheep was born In the future, cloning could be used to produce organs from single cells, or replace damaged cells from diseases such as Alzheimers and Parkinson’s
Used to replace lost limbs Constantly improving to replicate the functions of real limbs Being developed into “Bionic Prosthesis” which use the amputee’s thought process to function the prosthetic limb
Research in the medicalfield is ongoing, butwhen does it stop? Withadvancements such asthe Bionic Prostheticand mechanical organslike the Jarvik-7,maybe the idea aboutthe bionic human isn’tthat far off.
If we start using cloning tocreate organs and replacedying cells it will benefitour way of life in thefuture. Do we keepadvancing cloning to thepoint that we haveduplicates of ourselves toensure there is always adonor who is a perfectmatch available?
The bionic humans, andusing clones have been afuturistic ideal used inHollywood for decades, butis it possible for theseideas to become more thanjust a fantasy? If so, howdo we know that whathappens in the movieswon’t happen in real life?
The cycle of life starts at birth and ends with death Some cycles are unfortunately finished earlier than expected Medical advancements are being made to improve the way of life between birth and death
The advancements arebeginning to look asthough they may make itpossible to extend the lifecycle. No one wants tosee their loved onespass, but that is part oflife. Extending the cyclemay seem great, but inreality posses a lot ofproblems.
Some potential problems to extending the lifecycle are: Over population More demand on already diminishing resources Greater need for elderly care services Larger financial strain, forcing people to work longer
Countries like India and China already have a large population and if people have the ability to live longer, there will be a need for more food and housing to be available Certain countries already struggle to support the needs of their population
If the population is increasing, its going to demand the use of more natural resources The resources we have are already diminishing, such as our fossil fuels, and the creation of green house gases will be greatly increased
With people living longer there will be more demand for elderly care facilities, which will allow for more jobs, but since people would be living longer they would be forced to pay for the care longer than before People also would have to work later in life otherwise their pensions won’t be enough to carry them through
All the advancements in the medical field arebeneficial to our well being and way of life, butthe question stands as to when have gone tofar. It’s an ongoing debate in the medical fieldand will probably never be answered.
