Human Genetics - Video Response

We have learned the basics of genetic expression and the multitude of errors that may happen within the genetic code.  Mutation affects the resulting function of an individual.  In many cases, this function creates a fatal or less-than-optimal level of functioning.

The idea of genetic manipulation has been the source of many imaginative stories and controversies over the years.  However, the reality that we are close to taking control of our species evolution by selecting out traits is quickly becoming a reality.  Genetically modified organisms also offer the hope for many cures and not just the manipulation of harvested plant crops.  Based on the videos we have viewed I ask three questions for you to respond to.

1.  Should gene therapy be funded so that it can be available for all patients (support your choice)?  What do you see as the pros and cons of such a practice? (/5)

2. Do you think that GMO organisms should be developed?  Should there be guidelines to GMO development and, if so, what do you suggest? (/5)

3.To this point in human evolution we have overcome many of the selective pressures that have allowed our genome to evolve over the millennia.  Essentially many of our technologies have removed natural selective pressures and introduced new artificial pressures on our species.  Yet, even our technology and medicine allows members of our species with "weaker" genetics to reproduce and populate the next generation of humans.  With all our technology are we equipped to make choices about what traits are an advantage to future generation of humans?  Should we use the power to choose what positive traits should be selected for in our offspring or should we simply select against this we know for sure are disease causing?  What role do you think genetic engineering should play in our future? (/10)

Drugs and the Brain

The unfortunate fact is marijuana use in teenagers is on the rise.  This is linked to the fact that marijuana use is made to appear acceptable in pop culture, decriminalized by political powers, and lacking a body of scientific research on long term affects.  However, more research is going into the long term affects of its use.  It does not seem a huge mental leap to predict that studies will eventually begin to mount to show the negative affects of its use.  However, will evidence change its use/abuse?  We have known for a long time, with overwhelming evidence, that tobacco use causes a cascade of serious, debilitating illnesses in the human population.  Will our society make the same mistake with marijuana that we have with tobacco and alcohol?

You will read the following studies that have reported their findings to the public.
Your task is to submit a review of these articles via email.  Give a one paragraph summary of each article detailing the duration of each study, the individuals involved in the study, and the findings of each.  Lastly the fourth paragraph of the review should include your opinions on Marijuana use among your peers.
