Our Body After Death – Special Ways to Rest in Peace

Most religious and spiritual groups believe that the body is occupied by a soul that lives on after death. For centuries humans have been using different methods to ensure that a body remains at peace, after the soul has departed. With the changes in the world, due to more advanced technology, the way we put our loved ones to rest is also changing and new methods of preserving our memory include:

  1. Becoming a Diamond

Cremated bodies can be made into synthetic diamonds, in a process which heats extracted carbons from a loved one’s remains to extreme temperatures. These are then placed into LifeGem’s diamond press, a 13,000-pound industrial machine. Once the diamond has been made it can be cut and polished, as well as have unique features engraved on its surface.

  1. Floating Island Burial

The Buddhist traditions observed in Hong Kong require proper respect to be shown to the bodies of those that have passed on. The country has been running out of space to store their ever-increasing number of dead. Burial plots in Hong Kong are now being reused and families often wait up to 56 months to get one. This means that most of the bodies of those that die are cremated and the country has also begun running out of space to store the urns.

To solve this problem Hong Kong has teamed up with British architectural firm, BREAD Studio, to create a floating island where the ashes of 370,000 people can now be housed. The island is called ‘Floating Eternity’ and is located alongside the harbor. Visitors can pull up by boat, place their urn in a designated niche or sprinkle the ashes overboard for a burial at sea. The circular walkway has also been designed to ensure that the view from any angle remains unobstructed.

  1. Coral Reef Burial

Eternal Reefs has revolutionized a way for deceased loved ones to become a part of the ocean’s ecosystem. Cremated remains are put inside reef balls, which are specially designed to repopulate the oceans reefs after their drastic decline in recent decades. The unique design encourages sea life to attach itself to the surface of the balls and grow outward. The reef ball can also store personal memorabilia, such as dog tags for navy veterans.

  1. An Atmospheric Release

Mesoloft is a company that takes cremated remains up in a balloon and releases them into the atmosphere, where they float around the Earth before drifting back to the planet’s surface to settle on various landforms. Other ashes will pass through clouds to become a part of rain or snow. The release is recorded and played for loved ones at the deceased’s funeral, or a special memorial service.

Stem Cell Storage – Preparing to Combat Future Ailments

One of the major quests of the human species is finding a way to prolong our lives. Unfortunately, as we age our stem cells decrease and deteriorate, making us more susceptible to age-related illnesses. Scientists believe that many of these diseases can be slowed down, or stopped entirely, using our own stem cells. Although more research needs to be conducted into ways to use them to prolong our lives, and our healthy years, one study has already shown that mice injected with stem cells began aging more slowly. The best stem cells to be used in any medical process would be the ones that we have in our youth, before the deterioration process begins.

Forever Labs has developed a system to harvest and store these ideal stem cells for future use, where necessary. The company has partnered with doctors, predominantly plastic and orthopedic surgeons, to extract stem cells which their labs will keep for an annual fee. The extraction is a fifteen-minute process, and the company’s website provides those interested with a list of doctors that do the procedure. The process is virtually pain free, with little or no recovery period. This means that you could essentially be saving your own life, with an effortless procedure, conducted during your lunch break!

The stem cells are collected from the bone marrow, near the hip, which has the highest number in the body. The bone marrow produces most of our blood, supports the immune system and the connected tissue, as well as the vasculature and soft muscle systems. Scientists at Forever Labs believe that replacing the stem cells in the bone marrow (with younger ones) as we age, can help to prolong our lives and health. Most age-related diseases are caused by problems arising at the cellular level, which then extends to the tissues. If they can be addressed at this stage they can be controlled before they become debilitating, essentially prolonging a healthy life.

The procedure is straightforward, harmless and, for most patients, risk-free. Those that may face risks will be told beforehand. Scientists continue to research the possibilities that exist with stem cell treatment including: combating Alzheimer’s, osteoarthritis, heart disease and strokes. A study conducted with rats has shown where stem cell application may even be able to treat alcoholism. Regardless of the cures that will arise, most scientists believe that harvesting stem cells at a younger age will give individuals a higher fighting chance if they find themselves dealing with age-related diseases in the future.

Biohybrid Robots – Artificial Intelligence with Human Features

The human body works in remarkable ways. Our skeleton creates a base for muscles, ligaments and joints which make it easier for us to perform intricate tasks. Although robots can do many of the same things humans can, their ability to maneuver is limited in several ways. Biohybrid robotics is a field that is rapidly expanding and consists of equipping robots with biological tissue. This will enhance their maneuvering abilities and the tasks that they can accomplish, increasing their functions exponentially. Researchers from The University of Tokyo Institute of Industrial Science have recently created a biohybrid robotic finger with the ability to bend itself up and down. They published the results in Science Robotics recording that the finger remained functional for more than a week.

Their creation began with the construction of the finger’s skeleton using 3D-printed resin, with a joint and anchors for the tissue’s attachment. Electrodes that would stimulate the living muscle, causing it to contract, were the skeleton’s final addition. The muscle was made using myoblasts, stem cells with the ability to mature into several types of muscle cells. These were housed in hydrogel sheets that had holes from which they could be attached to the skeleton. To encourage muscle fibre to grow between the anchors, some striped structures were added. The muscles in the biohybrid functioned similarly to those in our body, as a pair, with one contracting while the other expands. This prevented them from shrinking or breaking down.

Once biorobotic construction and its range of motion has been mastered, the possible uses are endless. Currently, a robot’s initial movements are jerky, preventing them from being able to undertake specific tasks. The inclusion of muscle tissue would result in smoother, steadier overall movements. Scientists are planning to use these biorobots for more detailed exploration of the human body, as well as to enhance our medical capabilities. This could be partially accomplished by performing tests on the biorobots, instead of humans. In addition, they would increase the manufacturing ability of robots, currently limited due to intricate parts and assembly necessary, and their ability to monitor certain environments.

Despite the great benefits of biorobotics, the technology does have its limitations, including the need to feed these living cells. Until a way to do this can be found, the biorobots would have a limited lifespan. The surrounding temperature would also affect the length of time they could survive for, as well as their operating capacities. As the field expands, these limitations are expected to be improved upon, and it is almost a certainty that biorobots will eventually become a part of our daily lives.

The Future of Spying – Chemically Created Passwords

The safety of many countries depends on their ability to defend themselves during times of war, which often requires transporting secret messages. Each country has their own spies that are responsible for obtaining and transferring this information securely. As technology has advanced, much of this secret information is stored in password protected systems. Computers often generate these passwords which makes it possible for them to be hacked. This has caused ongoing research to develop secure ways of hiding information physically. One of these is chemical cryptography, which involves creating passwords made from atomic structures.

Although not currently on the market, the technology shows immense potential. Messages would be secured by coding them in the form of small molecules, that would be absorbed by a napkin. They could only be decrypted using the key, which would be the molecule’s structure. The method has been developed by German company Karlsruher Institut fur Technologie. Their molecular library has at least 500,000 keys that, because of their structural diversification, would be impossible to decode without the sample. The message can also only be revealed after being scanned with the same equipment used by microbiologists to analyze new compounds in their research. Researchers plan on expanding the technology to including DNA which would increase the number of keys that could be made, making passwords even more secure.

The small size of molecular keypad locks also makes them difficult to detect. This is a form of steganography, where both the locks and keys are hidden. This technology was first developed in 2007, with the possibility of only one password being used per lock. Researchers have recently found ways to allow locks to have multiple passwords, according to a study published in Journal of the American Chemical Society. Most florescent molecular sensors generate discreet optical signals but the one used was able to generate a unique optical ‘fingerprint’ for each chemical, making it possible to differentiate between them.

This inclusion enables the system to operate like both an electronic keypad lock, which can be opened by entering the correct password, and a biometric lock, opened by recognizing a unique signature (such as a fingerprint). Electronic locks have accessible entry keys, placed on the keypad, and can be opened by anybody that knows the password. Biometric locks are more secure as each user carries their own key. The molecular keypad lock would require both a password and optical fingerprint and would increase security even more, as the key is chemical and the correct password would need to be entered.

Designer Bodies – DNA Manipulation to Recreate Ourselves

Many people often wish that it was possible to recreate themselves to be ‘perfect,’ physically, mentally or both. To fulfil this desire, scientists are exploring how DNA manipulation can be used to change plants and animals, as well as redesign our human bodies and minds. DNA is the source code of all forms of life, and changes in our genetic composition may make it possible for us to survive longer, and in more extreme situations. Founding Director of the Life Sciences project at Harvard Business School, Juan Enriquez, has spoken about using gene editing to take evolution into our hands, instead of depending on nature to choose which species survive. One of the easiest ways to accomplish this is through CRISPR, a genome editing technique that can modify a specific part of a gene without harming any others.

Enriquez pointed out the evolution of science itself, which used to be about discovery but is now about creation.’ Technology has changed the pattern of our world from ‘survival of the fittest,’ to one in which humans can decide which species live and die. We can also modify the genes of plants and animals to live in conditions they would previously have been unable to survive in. Although the ability to modify the body of different species is phenomenal, an even greater achievement is the ability to recreate our minds.

DNA manipulation means humans can decide who they want to be, and which experience they want to dominate their lives at any given moment. The mind can be shaped by altering, creating and deleting memories, which are the foundation of who we are. This would allow people to change their entire identity, past experiences and personal beliefs almost instantaneously. This altering of self, with technology, raises many questions and the possibility of harmful or immoral consequences. Would justice still be served if a person had no recollection of committing a crime? Would other members of society be affected if somebody ‘created’ a relationship in their head? Would existing financial obligations be avoided by changing the circumstances in the mind?

Although the question of the morality remains, the ability to change our DNA would be frequently lifesaving. In addition to altering or removing DNA associated with genetic illnesses, the length of time taken to make vaccinations would decrease significantly. Future survival would be guaranteed, even in the event of a catastrophic planetary event, as DNA could be altered for life outside of our atmosphere. Space exploration would increase exponentially, as Enriquez believes that the human species was created for expansion. ‘As explorers at heart’ we will always be drawn to the unknown, breaking barriers, creating and recreating, with DNA manipulation being only a part of the process of expanding our beings.

Future Pandemic – Is an Outbreak Inevitable?

Scientists, and other researchers, spend much of their time developing ways to prevent possible disasters, both natural and unnatural, from taking place. History is famous for repeating itself, and there have been several recorded pandemics that were responsible for the deaths of a large percentage of the population. The Spanish Flu outbreak, in 1918, is one of the most deadly examples. An incredibly contagious form of influenza, this virus affected everybody and spread to some of the most remote parts of the planet. It is estimated that, over the course of two years, the Spanish Flu killed between 50-100 million people worldwide.

Although our medical techniques, and pharmaceuticals, have advanced significantly since the early 20th century; The General Director of the World Health Organization (WHO), Tedros Adhanom, has addressed the fact that we are still as unprepared for a pandemic as we were at the beginning of the 20th century. The dreaded event could begin in any country and spread quickly, before most nations were aware of its presence. Although this is a scenario we have witnessed many times in horror books, and films, the possibility of it happening in real life is much higher than most of us would like to admit.

Tedros pointed out that, ‘Universal health coverage is the greatest threat to global health.’ He went on to explain that as many as 3.5 billion people still do not have access to essential health services. Others that can attain the services are often forced into poverty, because of the high costs of this care. To avoid this problem many people neglect seeking medical treatment, even when it is necessary. This results in many illnesses progressing further than can be treated, and an unnecessary spreading of infectious diseases. This negligence could result in the earliest signs of an outbreak being overlooked.

Each country’s health organization relies on funding from their government to monitor the spread of diseases, as well as ensure the proper treatment. The (CDC) Centre for Disease Control and Prevention, in the United States, has recently announced that its budget for the epidemic prevention programs is being cut by 80%. In light of a possibly outbreak occurring at any moment, other countries are also experiencing the same difficulties. This demonstrates that governments are viewing healthcare as an unnecessary cost, instead of a necessary investment.

Tedros pointed out that healthy citizens are an advantage to the economy of any country. It has been proven that proper healthcare from children are in the womb, which is continued throughout their childhood, helps to make them stronger members of society. He also noted that at the moment a possible pandemic couldn’t be predicted, but dreads the terrible toll it would take on humanity. Despite there being no guarantee that a pandemic free world will ever be created, he is urging that we take back the control of our own lives. The best way to ensure our survival is by governments investing in proper healthcare, in every way possible, for each and every one of its citizens.
