MIT Finds Cure For Fear
Doom con runs away writes "MIT biochemists have identified a molecular mechanism behind fear, and successfully cured it in mice, according to an article in the journal Nature Neuroscience. They did this by inhibiting a kinase, an enzyme that change proteins, called Cdk5, which facilitates the extinction of fear learned in a particular context."
Because I saw some MIT guys talking to GIRLS!
President Bush introduced a bill this week to eliminate all research funding at MIT.

It is also called Liquid Courage. Drinking enough alcohol leaves me with no fear as well...
Why would you want to cure fear? Fear keeps me from giving in to a friend's bet and swallowing a live hamster. But seriously, unless you could target certain fears to help people with crippling phobias, this seems dangerous.
I am terrified at the implications of this!

It must have been something you assimilated. . . .
I see from all the comments that nobody actually read the article.
The 'cure' doesn't eliminate any and all fear. It doesn't address situational fear at all.
What it 'cures' is LEARNED fear responses. It's specific application to, for example, soldiers would be
for PTSD.
And even if there was a way to get read of all fear reactions, you'd still have a BRAIN and the ability
to choose not to do things that you reason are too risky.
Seriously, read the article. It's interesting.
Sheesh.
As I read this article, it isn't about making something fearless or preventing fear...it's more about increasing the rate at which a learned fear response decays in the absence of reinforcement. Essentially, the brain has built in mechanisms to "cure" fear on its own, given enough time without reinforcement of that particular fear. Inhibition of this enzyme--oddly enough one linked with plasticity and neural development--makes that process easier/faster.
If I understand correctly, then they are right in saying this would be potentially wonderful for treating cases of PTSD where the fear response does not significantly decrease even at points in time far removed from the initial trauma, but I don't think we have to worry about inhibition of this enzyme erasing people's ability to feel fear or leading to fear-based weapons systems. Those things are almost certainly possible (lesions on the amygdala are thought to tame animals by destroying their ability to feel fear), but I don't think they'll appear as a result of this study.
The first post is more correct, as the drug might actually apply in a situation involving girls. The drug treats learned fear, not the innate fear of combat. It will be used to help control post traumatic stress disorder. Arguably, fear of women is a learned fear similar to PTSD.
