Netflix pays its ISP for the ability to send content. Comcast customers pay their ISP for the ability to receive content. I don't see the problem here.
"a high correlation was found between higher bedroom light levels and increased propensity to be overweight or obese" - correlation.
"The Light Might Make You Heavy" - causation.
Dammit guys. -_-
Also, the connectivity is lost. You can't tell which neurons are connected to which other neurons. The overall circuitry, essential for the functioning of neural networks, is invisible. All you can see is points of contact between neurons.
Perhaps combining this technique with super high resolution diffusion tensor imaging would be a way forward. Although, as far as I know, DTI is nowhere near neuron or axon resolution as of yet.
Also, only protein -> DNA and protein -> RNA information transfers remain unknown. See reverse transcriptase and prions.
