[Johnathan on...] It's SCIENCE!

A fundamental issue in Quantum Mechanics is known as the "Measurement Problem", or more commonly referred to as "The Observer Effect". It is simply the unavoidable effect of "observing" subatomic particles using light. We can't see any object or event in nature without first bouncing light waves off of them. This "bouncing" is what directly disrupts the outcome when observing such tiny objects. It's like hitting a basketball with tennis balls in order to measure it's position. The act of measuring it (or the method used) directly effects the outcome.

[Gamma on...] Artificial Hearts

Synthetic organs: the holy grail of the biomedical technology. With the ability to produce organs artificially, we eliminate the need for donor organs from recently dead things. There are a number of issues that crop up when you try implanting foreign objects into the human body. Rejection, clotting, and infection are just of few of the biological issues that such procedures have. You also have to make sure the device is small enough to fit in the body without squishing anything, and then there are the issues with maintenance and power. It’s all very complicated, rest assured, but we have a few working artificial organs out there. Most notably--the Jarvik artificial heart, which has been the super star of the artificial organ world for a while now. However, as with all things in life, a challenger has appeared. Drs. O. H. Frazier and William Cohn have developed a new and way more awesome system than the shit that Jarvik has been working with.
