“What is very disturbing to me is that people like Mr. Akin who have postulated this secret mechanism for avoiding pregnancy have developed their own make-believe world of science based on entirely self-serving beliefs of convenience or just ignorance. I don’t think we want these people to be responsible for the lives of others.”— Dr Paul Blumenthal discussing Rep. Todd Akin, cited by Maureen Dowd in Just Think No via NYTimes.com (via underpaidgenius)
We all need to clear our heads, sometimes literally — and now scientists have learned how our neurological plumbing system works.
Every organ produces waste, and the brain is no exception. But unlike the rest of our body, it doesn’t have a lymphatic system, a network of vessels that filter out junk. Now, a new study of mouse brains suggests how ours handle waste: by rapidly pumping fluid along the outside of blood vessels, literally flushing waste away. The finding, reported Aug. 15 in Science Translational Medicine, could hint at how diseases like Alzheimer’s develop and might be treated.
