Many of us would want to be immortals. Although it is possible in
sci-fi movies and even comics, modern day scientists are still working
on technologies that might one day allow us to live a thousand years.
Today in this article, we will explore top 10 such medical technologies
that are helping us live longer.
10. Neuroprosthetics

The
general notion behind this technology is that a body part can be
replaced by an implant that functions like natural body part. These
implants take input from nervous system in order to respond to an
outside stimulus. They can act as a replacement if someone loses his
limb in an accident. As long as Steve Martin’s
The Man With Two Brains notion that
“your brain dies last” hold true, then you can one day have a body of
replaced parts. Long story short, we might look like Robo-cop, only
better.
9. Brain-Computer Interface

If
you have seen “the Matrix” movie, you can easily relate to this
technology. The idea is that the computer and the brain can communicate
and yes, this technology exists. Maybe not to the extent as shown in
movies but for now the technology is limited to repair functions. In
short, a brain computer interface can interact with an existing neural
function to restore cognitive abilities and functions. Naturally why
would the scientists limit themselves to just restoring and repairing,
they will strive to achieve greater good; that being to enhance the
already existing capabilities. Imagine, you could learn anything you
want just in a jiffy, wouldn’t that be a sight. Through this technology
brain damage will never be permanent thus prolonging life.
8. DNA Repair

DNA
is more than just strands of cell; it is like a computer that directs
and repairs your cell. If we manage to repair it or give the DNA the
ability to do so on its own then we have more chances of surviving
longer than we should. For example, cancer is the breakdown of DNA’s
capacity to mend itself, so the key is in understanding how it works and
maybe jumpstart it in order for it to repair itself. For simpler
understanding, DNA is just like any machine, with regular tune-ups and
oiling, it works just as fine. Also once the understanding of its
working is there, we can enhance it as well. Controlled mutation may
even give us super powers and Professor X will just be another bald guy
in a wheel chair.
7. Anti-Aging Enzymes

Research
has concluded that two enzymes SIRT3 and SIRT4 are responsible for the
process of aging. The cells’ ability to divide and reproduce when
hindered shows the signs of aging on humans. If science can restore the
depleted cells, the effects of aging can be eliminated. For easy
understanding, let us compare the process of aging with the analogy of a
battery. A used battery can be recharged, similarly the cells can be
repaired and restored in order to remove the effects of aging or even
more stop the process. Above explanation implies that in the near future
scientists might be able to prolong life by eliminating the effects of
aging.
6. Partial Brain Transplant

The
working of the brain is still a mystery to the medical practitioners.
However an interesting discovery was made by Dr. Dorothy T. Krieger in
1982. She implanted healthy tissue on a damaged part of the brain and
not only the brain accepted and assimilated the healthy tissue but it
also functioned like a normal brain. She bred two mice, one was normal
and the other lacked the ability of producing L.H.R.H. She employed the
same procedure and the mouse that originally lacked the ability was now
producing L.H.R.H. Scientists are trying to utilize the same principle
on humans, if they are successful in “seeding” the brain, the growth
will also be possible thus increasing the life of humans.
5. Organ Printing

Organ
printing resembles organ donation only in this form cells are used to
repair the defected organs. Printing process is said to make organ’s
layer and it does it one at a time just like a dot matrix printer.
Scientists are currently working on something relatively simple such as
vessels. If the technology finds its way, then there will be no need for
donors, all that would be required will be some cells from the patient,
also eliminating the fear of rejection of the organ.
4. Artificial Organs

The
technology is fairly simple to explain but rather difficult to achieve.
So far scientists have successfully transplanted a heart and patients
can live several years on this artificial heart. The artificial assembly
replaces the bottom two ventricles of the heart. It all started in 1982
when one Mr. Barney went through a transplant and getting an artificial
device within him pioneered by Dr. Robert Javrik. Due to availability
of donors, advances in such technology is hampered but with time, we
will see much more than just a heart.
3. Downloading Your Consciousness

This
technology comes straight out of a comic book. The notion behind this
technology is that one day people will be able to live in computers for
thousands of years. The idea is that a computer will have all your
information on it integrated with artificial intelligence that would
allow us humans to live within a computer. This is presented by a
scientist Ian Pearson who is working on this technology as you are
reading this article. It is said that by 2050, if you make for that
long, this technology will be ready and we will have our very own
silicon soul.
2. Suspended Animation

The
idea is to increase the time so that the patient can be treated within
the “golden hour”. The first hour after a tragedy strikes a patient is
called the golden hour. Statistics tell us that most of the battlefield
deaths occur when the medical team fails to reach the patient within the
first hour. This technology is aimed to pause that time, implying
putting the soldier in hibernation as to prolong the time for medical
teams to reach. And this is exactly what Defense Advanced Research
Projects Agency, and the Texas A&M Institute for Preclinical
Studies, is working on now. Although currently they are working on
squirrels and pigs, hopefully someday even humans will benefit!
1. Whole Head and Whole Body Transplants

The
brain is known to be autoimmune. What that infers is that the brain
does not reject a brain as it rejects other organs such as liver or
kidney. But the challenge with this technology is that it rather
difficult to transplant a head, specially have to attach to the nervous
system in such a way that the resulting patient is not a quadriplegic.
It not easy to detach a head and then attach it again on another body
however in 2001, Dr. Robert White transplanted a head of a monkey on
another animal. In the future maybe this technology can be successful
and voila, all you will need would be a body to attach yourself to and
you could live for thousands of years.
