Quatum Dots in the Brain?->

Submitted by

lee1 writes "Quantum dots are nanometer-sized, light-sensitive, semiconducting
particles. Researchers at the University of Washington have discovered
that when these particles are in proximity to a nerve cell, shining
light on the dots causes the neurons' ion channels to open and the
nerve cell to fire. This opens up a new vista of possible treatments for
various brain disorders. The dots can be implanted by coating them with
molecules with an affinity for the targeted tissues and injecting them
into the bloodstream. After that, the main problem will be to figure out
how to shine light into the brain. But there are high hopes for the
treatment of retinal disorders, where this problem is, obviously,
already solved."

so many top level mathematicians use amphetamines

Do you have a reference for that? I know about Erdos [spelled wrong because Slashdot can not handle Unicode and I'm too lazy (no speed) to see if there is an HTML entity for what should be here], because I read his biography My Brain is Open: he could not do mathematics without speed. But I'd not heard that it was a widespread phenomenon.

you give it to them. If their symptoms go away they need it, else they don't

In fact, it is just this flawed methodology that created the false idea in the minds of researchers that speed was actually helping these children. This false idea is what has led to the current massive overprescription and probable consequent harm to millions of patients.

But when they enthusiastically appease other, extra-legal demands for censorship they sometimes censor results worldwide, including those served to the US. Did you know that when you search on Google or YouTube that the results returned by Google are partly determined by the preferences of various Islamic pressure groups and foreign governments, including Pakistan?
