Life expectancy is constantly growing. We are constantly improving their knowledge about medicine and the human body. We eliminated many diseases, discovered powerful treatments, and figured out how to keep the disease, which once can kill us. We longer and longer trying to maintain people alive, thus bringing us to one of analogues of immortality — regardless of whether it's biological, digital or cybernetic immortality. Let's look at technologies that will help us to achieve unlimited life span.
Blood is so important to our survival that the epithet "blood" came to mean the need. Excessive loss of blood means that life may be interrupted, so blood transfusion has become an important medical tool. However, there are two main problems associated with blood transfusion. First, by blood must to sacrifice other people, which means that the deficit is always the case. Secondly, we all have different blood types, and transfusion of the incorrect blood type will lead to attack the immune system and developing horrible complications.
Science has managed to solve both of these problems by making the red blood cells of a universal O-type (which can be sent without any complications). The first time the blood was made in the laboratory, and this may lead to the end of donor transfusions and the beginning of the industrial production of blood.
Growing body parts
There are several common themes in science fiction, some of which are highly plausible. When we see interstellar travel, alien life, food tablets, we can represent their potential impact on human life. But some things seem insane — for instance, growing body parts in the lab. Such bodies don't just look anatomically correct, but still work well. What we did on this ground? Well, have been successfully transplanted vagina and nostrils.
We wrote about the first time in the history of a woman born without a vagina — or vagina which was incomplete — transplanted lab-grown counterpart. The woman watched for eight years before scientists were able to make progress. During all this time the woman and her new body was functioning completely normally without adverse side effects. Patients who have lost part of their noses because of skin cancer, also received new noses grown from the cells of their skin.
The treatment of paralysis
Spinal cord injury are among the most devastating injuries, having gone through that man does not guarantee a full recovery. The spinal cord transmits information to every part of the body, so injuries to this area almost always lead to paralysis, complete or partial. People remain limited in the movements for life, not to mention pain.
A pioneering study of the role of electrical impulses in the nerve tissue of the spine has allowed scientists to bring back the ability to move people who would have remained paralyzed for life. The patients included in the study were able to move previously paralyzed body parts after exposure to electrical impulses to the spinal cord. In combination with traditional physical therapy the results were even more interesting. Once hundreds of thousands of people without the ability to walk again will be able to move my feet on the ground on their own.
The process of aging
Following in the footsteps of his contemporaries, caring for the skin, and fashion trends, a group of scientists discovered a chemical in the blood of young people that can have a significant impact on the body in old age. It was not a fleeting one study of three separate groups came to the same conclusions in experiments with mice. The study found that transfusions of young blood reverses age-associated memory impairment, learning disabilities, brain function, muscle strength and endurance.
Two of the groups even claimed to have identified one of the chemical that was responsible for this effect is age-reversing. Because the study was conducted on mice, while it remains unclear whether the result is identical to humans, but scientists believe it to be. Clinical trials will begin within a few years and could potentially open the way for these injections from aging.
Drug testing the next generation
No matter how far we've come as a people of incredible forgetfulness and laziness elementary accompany us constantly. Medicines are an extremely important part of health many people, and for some to forget to take medications can mean deadly. However, with the development which to some may seem incredible, but intimidating for others, there will be an electronic system that will monitor the medication in your performance. Tiny sensors and beacons will tell you when you need to take the pill, and you will know that never miss one.
Continuous monitoring if you don't like, have other advantages. The system can monitor the body's response to certain medications, giving you and your doctor information about how your body reacts, if something goes wrong.
Heart and its well being is the key to a long and fulfilling life. The main cause of death in many countries around the world is heart disease, not AIDS or cancer. Every few seconds from heart disease kills one person in the world.
However, scientists have recently transplanted genetically modified pig heart baboon, and it worked properly during the year. This study breathed in the medical world hope that one day animals will be able to provide an infinite number of hearts and other organs of people, significantly increasing their lifespan.
Reduction of disability caused by a stroke
Strokes are awful and often deadly. In cases where they don't kill, they can leave the person unable to perform even simple actions significantly affecting the quality of his life. Independence and autonomy almost always end, and people can't control their body as before. Previously, such people were little able to help the doctors. Now, however, scientists are using revolutionary new procedure for the treatment of such terrible disorders.
Inserting stem cells into the brain of patients, the researchers were able to restore the ability to move limbs and perform tasks that were previously impossible. The people involved in the experiment, see it as a sign of hope for victims of stroke.
Printing a new heart
We have become accustomed to the importance of maintaining the heart and careful attitude toward it, is as important to us the possibility of transplantation of organs for the sustenance of human life. A special breakthrough in this field happened with the development of 3D printing. Some industry representatives suggest that the first Bionda heart will be printed in the next ten years. A group of scientists from the University of Louisiana has taken major steps towards the fulfillment of this prediction.
Using fat cells and collagen, the team was able to print working components of the human heart. They use the analogy of an airplane — a complex machine is made in parts and then going to explain why they just can't take and print a whole heart, and why it is necessary to collect in parts. But with the possibility of a partial print ten years look very reasonable.
Since the first cyborgs appeared in science fiction, scientists are looking for the way to create bionic body parts. This would immeasurably improve the lives of amputees, and every bit of research brings us closer to the understanding of the complex communication system between our brain and our muscles. And, it seems, all those efforts finally began to bear fruit. DEKA — driven impulses of the brain to the prosthetic arm is not an ordinary Supplement, it's a miracle.
Invented by the same man who invented the Segway, the arm can perform such fine and graceful action, as to fasten the jacket to hold the egg, not crushing it, to unlock the door the key and more puzzles than people with normal working hands. The bionic arm is also easily adaptable, that is suitable for people whose hands are amputated at the shoulder, elbow or wrist.
In science fiction one word that is not very fond of scientists. It's cryostasis. Leading surgeons prefer to call it "emergency preservation and resuscitation", although they acknowledge that it suspends the lives. Not so long ago we wrote about the resolution of the first clinical trials of this suspended animation. The patient's blood replaced with a cold saline solution, which causes something like hypothermia, slowing down all cellular activity twice. Surgeons have more time to correct the problem. In theory, this procedure can save many lives. According to the inventor of technology Peter Rhee, the patients don't have to live in the course of this procedure, but they won't die.
In 2000, Ri has demonstrated this technique on pigs and it worked. Pigs suffered from massive hemorrhage, and then they were put into suspended animation and "back to life". In most cases, their hearts again began to beat, and cognitive or physical functions are not affected. Now Ri is waiting for a suitable candidate among the people. They change the definition of death.
