Fearless woman's life in science

Science Friday had a segment last week on Prof. Daniel Tranel's research with a woman known as "SM" who experiences no fear because of lesions to her amygdala. She has experienced this condition from birth and began working with the group for two decades. She is quite accustomed to participating, to the extent that she will call the lab and ask if there are any projects coming along if she has not heard from them in a while. What a fascinating relationship with science she must have.
