Forensics Quiz

A 20 years old man, who found spine on Thompson Creak Trail with a bullet wound, died out from lung bleeding.

First, the entrance of the wound was on the left side third rib, and exit wound was 5 cm above the belly button in the umbilical region, in a 45 downward angle. Also, the examiner observe a 8th rib fractured through X-ray.

All evident show the murder stood in front of the victim and shot him from a higher elevation.
Since the bullet went the victim's left side third rib, it may hit victim's lung or liver. Both of lung and liver provide blood and oxygen to the brain, if these two organelles are damaged, then the brain would shut down very quickly.

1. This is not a suicide because he cannot set up a gun at a higher spot and run down to a lower spot, and trigger the gun to kill himself.

2. The murder did not kill him from the back because the bullet enter from the front, and he was found spine.

3. The victim did not die out of his internal problem, no tumors was found in his body. He was murdered by the bullet.

   I have to say that I was shocked after I watched the video, how do they create all those human organs? Although the doctor shows some process in the video, I still do not understand how do the just use a normal printer, and just print a human organ. Also what is the problem that hamper these technology to be commonly used, and what are the differences between the human organs and the artificial organs? What are the side effects of replacing a artificial organs?

Why are the clones killed after they are used once? The woman who gave birth was immediately killed, but what if her sponsor needed a new heart in a year? Is she given a new clone to replace her old one? -- Mary Van Schaick


   I think this is a great question. The first thought that come our of my mind is "iphone". When people cracked their phone screen, they take their phone to the apple store, and pay 200 dollars to get their new phone. But many parts that in the cracked phone still work perfectly fine. Where do those trade in phone goes? Also, i think it will be even more ruthless if people cut out clones' body parts for multiple times, which means those clones have to suffer from pain for multiple times...

Questions

1. Are all the pluripotent stem cells the same? For example, is the stem cell from my skin as same as the stem cell from my hair? Is possible to exchange stem cell? Can I save my stem cell right now, and my grandson use my stem cell in the future?

2. If they use the clone technology, they still need to produce a embryo, and the embryo still have to grow up in a human body, however; in the movie, they did not explain this step and new clones just jump out of a bag of water! Is is possible that the clone technology can get to the stage that they can eliminate the process of putting the embryo back to a human body?

3. If human can start live much longer or eventually live forever, is there enough natural resources to be used for human beings? If everyone can live so long or forever, would they still have the desire to produce next generation? Then the entire human beings will be against the Revolution theory because human can only degenerate or remain the same.

4. Where can those clones go when they get out of the "island"? Their intelligence level is as same as a child, and there is already another he or she somewhere on earth. Also according to the movie, those clones are either very rich or powerful! Then it will definitely become a social issue because we definitely do not want to have two same president or two Justin Bibber... My question is how to settle down all the clones?

Your inner healers

  This is a absolutely astonish article, if this pluripotent stem cell technology become common accessible treatment, it will definitely change the entire human society in the future. I actually remember that I saw a advertisement in Hong Kong which advocates people to save their stem cell right now, therefore, they could benefit from it in the future. During that time, I had zero understanding of stem cell, but after I had read this article, I just realize that the chance for me to use this technology in my life time is not impossible! If this technology becomes more mature, we can use it to cure any diseases, and human can possibly live forever.
However, it will cause even bigger social problems, if people are never going to die, then do we still need to produce next generation? Do we need to get married? Do we need to exercise... etc. Anyway, the discovery of stem cell sounds like a good news to me, I want to find a place and save up my stem cell as soon as possible.
