Let's Start with Rats With visions of hangovers dancing in many readers' minds (and brains), and in the minds of whoever saw them doing what people do when they are intoxicated (or saw it on YouTube.com); I thought I'd bring your attention to some rats. Science is learning more about why alcoholics are able to stay in denial, and why anyone should be afraid of bingeing.
One of the greatest challenges neurologists face is successful delivery of drugs to the brain. This is because a special filtering layer of tissue, called the blood brain barrier, protects the brain and spinal cord. The barrier acts like a molecular sieve, allowing only properly sized molecules through. This means that any medication needing to reach the brain (for example, to kill a brain tumor) needs to be small enough, and even then, it is difficult to target the drug to specifically reach the brain.
Rumors and gossip are a normal part of any work dynamic. We are taught at a young age that spreading rumors is mean and we should abstain, but most of us never really learn that lesson. What is it about gossip that makes a person feel better and why is it so hard to not participate? Is there a sociological purpose for rumors and gossip that makes it a necessary evil when humans are put in groups?
Researchers have recently discovered through MRI (Magnetic Resonance Imaging) that in some people the part of the brain that should react to punishment as a deterrence does not work properly. In these cases should the criminal justice system allow for a defendant to get off due to these brain differences?
