Science Journal 5: Wrinkle Creams Be Warned!


Wrinkle Creams Be Warned!

Book:  La Machine a Rajeunir

        In French class, we are reading a book about a teenage boy who discovers that after coming back from their vacation, his parents are growing younger!  The parents, who are around 40 years old, soon realize that they feel healthier and look thinner and better than they did before.  Their happiness turns to horror as they realize that not only are they growing younger physically, but they are growing younger mentally as well.  They soon begin to forget who their son is, and who they are to each other.  Through a series of adventures, their son realizes that they had sat through an age reversing machine that had been marketed as a silly museum attraction.  The machine used microwaves to make his parents younger, and can do the opposite as well.  In the end, the son manages to figure everything out, and all is well.  This book is very basic, since we wouldn’t be capable of understand much more. 

        Because of the easy to follow nature of the book, the science in it is understandably shaky, and is classified as science fiction.  Though the science in this book doesn’t even come close to pseudoscience, and is used playfully, I found two interesting concepts in the book that I wanted to look into a little bit further:  microwaves and age reversing. 

        Microwaves are a form of electromagnetic radiation, like visible light.  They have a long wavelength, a low frequency, and are commonly used for communication devices and heating food items.  Microwaves are very functional, but can they change us physically like they did to the parents in the story?  Microwaves heat food by making the water and fat particles in the food to vibrate, causing friction.  Recently, we had a discussion in science class about cancer and its connection to cell phones.  Generally, cell phone companies recommend that users keep cellphones at least a few centimeters away from them while they are talking on them.  Cell phones use microwaves, which are known to cause cataracts if exposed to them for too long.

        The Food and Drug Administration has approved microwaves, and has placed certain safety standards on them that microwave oven manufacturers must meet in order to sell their product in the US.  On the FDA’s website, it states that the long term effects of low exposure to microwaves have not yet been determined, but that there is very good evidence to suggest that the amount of microwaves you are exposed to while using a microwave oven (a maximum of 5 milliwatts throughout its lifetime) is too low to do any immediate harm.  As a child, I had always been told by others older than me to not stand too close to a microwave, and to not look directly into them.  By doing this research I am able to clear up for myself some of the rumors and “mystery” surrounding microwaves.  Though these people had my best interests at heart, I no longer am unable to show them proof as to why looking at my food very often while it’s in the microwave (which, due to my low level of cooking skills I need to do to ensure the food is edible), will not cause my eyes to burn out.

Another aspect of the book I found interesting was the age reversal of the parents.  This brings up many questions for me.  Though I know this is not yet possible in real life, are ideas being tested?  Scientists writing for the Nature science blog have found an enzyme, telomerase, which strengthens the telomeres:  “junk” lines of DNA that are found on the ends of chromosomes.  By controlling the telomerase activity, scientists were able to prematurely age rats.  They were also able to reverse some of the effects of this aging by manipulating the telomerase again.  Though this research is very interesting, it will take a long time and a lot of hard work for scientists to be able to transfer this knowledge onto humans.  During the testing phases, who will scientists test on?  Will there be any long term effects of becoming younger?  Will people be able to choose when they want the process to stop?  What if this process is used for harm?  With age reversing, many questions also arise in regards to managing population.  People will live longer and have more time to reproduce, so the population of the world will drastically increase.  Also, managing people might be a problem.  It will be difficult for governments to set legislation is regards to new age laws.  For example, can a 40 year old who has become 15 legally drive?  It is very interesting to see how society reacts when new technology is invented.  We have been through problems like this before, and are currently going through them.  For example, the internet and computers aren’t very old yet, and many governments and companies are having privacy issues, and intellectual property issues.
