Virginia Postrel: Well one issue is one that I’ve already touched on, which is the issue of what does it mean to understand human beings as biological creatures, as material, as manipulable? Aside from the obvious benefits of being able to cure diseases and extend life, which have their own implications for societies . . . If everybody starts to live a long time what does that mean? We’re already experienced a doubling of life expectancy worldwide over a hundred years or so. Really quite remarkable. That changes the way societies organize themselves. Not in the sense that people say, “Okay. Now we’re going to get married later and have fewer children.” But it happens partly because of life extension. There’s that . . . sort of the obvious social consequences, but then there’s the deeper philosophical issues. If we are really material, what does that mean? How do we think about that? What do we think about consciousness? If it’s an emergent property of chemical reactions as opposed to a little ghost in your head, does that make you feel worse about yourself in the same way that maybe if you have to give up and be . . . universe centered on earth and man, does that make you feel worse about yourself? You know amazingly enough we got use to that, and we don’t feel worse about ourselves than we did with the earth as the center of the universe. I think we’ll get over this other too. But it raises a lot of issues. What do you do about when you find the biological roots of certain kinds of criminal behavior, or socially destructive behavior? How do you deal with that? It’s a deep, difficult question, especially if the person hasn’t actually done anything bad. How do you think about that? Or if they have done something bad, then you can say we identified the gene that led to this personality disorder. Does that get them off if they killed six people or something? So that, I think, is one big area.
Technological advancement and the ensuing social consequences and philosophical debate.
Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
