Freezing a Human Body and Bringing It Back To Life

-

Freezing a human body isn't as difficult as it may seem, and it could possibly be a way to escape death.  

Freezing a human body is a subject almost as old as time. It's been fantasized about, written about in books, and made appearances in movies. There's theory all around the world about people freezing their bodies and still waiting it wake up. Now freezing an animals body, such as a small frog, is possible but there is Abigail different between a frog and a human. Blood plasma, a heterogeneous mixture is in the blood, separate from the blood cells is replaced with organ preservation solution.

 Before that, when a person is declared legally dead, the cryonic company will dispatch a response team in order to keep that persons blood in pumping around their body. The body will be injected with various chemicals, to try and reduce any blood clotting or potential damage to the brain. When the body reaches the facility, it will be cooled just enough, before water's freezing point. The body blood vessels with be injected with cryoprotectant solutions, in order to stop crystal formation in. Afterwards, the body will be cooled to -130 degrees Celsius. The final step to preserving a human body comes with placing the corpse in a container, which will be lowered into a tank filled with liquid nitrogen which is kept at -196 degrees Celsius. Although it seems like a dream to live forever in a cryogenically frozen chamber, there's a big chance it wouldn't work. Is a persons body is frozen below -5 degrees Celsius, than the after inside their cells with freeze and crystalize. This crystalization of the cells is although more dense than water, but it takes up a lot more space. The crystals can puncture through the cell membranes and cause severe damage. 

 Now there are a lot of ways, when written on paper of how freezing someone's body wouldn't kill them, not bring them back to life. But there are cases that show otherwise. With advancement in technologies, or just dumb luck it's getting easier to make that possible. Maybe somewhere in the next 50 years it may become the norm to cryogenically freeze your body for an amount of time and then wake up. As
 technology progresses and our bodies adapt to new environments, it could become more than possible to cryogenically freeze our bodies for maybe 100 years.

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
