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.
I came here to nominate Descent as well. Not sure if motion detection would be accurate enough, but it's time to bring back dogfighting with six axes of movement! And rotation! And charge-up fusion cannons. =)
Also, I'd be interested to see how (or if) they managed to completely wash off antibodies between scans without damaging the tissue or disrupting synaptic structure. Many synaptic proteins recognize and bind each other in the same way that antibodies bind their antigens, so it stands to reason that disrupting antibody binding would also disrupt the binding of these proteins.
This is immunohistochemistry, just scaled up to many different antibodies for the same sample and realigned in space.
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.
DNA polymerase does not transfer information from itself to DNA. It reads from a DNA strand and creates the complement of that strand. It is responsible for DNA -> DNA information transfer.

The site shows kids playing with the reader, implying that they're targeting users that you wouldn't necessarily trust with an iPhone or iPod Touch. However, I'm not sure I would trust kids with a $99 reader anyway. You could probably get a used previous-gen iPhone or iPod Touch for that much.
I was referring to the beginning of 2001: A Space Odyssey by Arthur C. Clarke, which is what the OP was referring to with the black obelisk. Please read the first paragraph of the plot summary here.
Yeah, which inspired us to start stabbing pigs and eating meat instead of just plants...which led to more available calories to feed our growing brains. See, it's all logically consistent.
EEG is non-invasive because it doesn't require any surgery. Electrodes are simply stuck to the outside of your head, usually with a conductive gel to help minimize electrode-skin resistance. The electrical activity of your brain is recorded by measuring changes in electric potential conducted through your skin, relative to some reference point. The advantage of EEG is that it's noninvasive. Anybody, with a little practice, can place electrodes correctly. If you wanted to make a gaming system using brain activity, this would be the way to go because people wouldn't have to have surgery just to play Super Mario Universe or Final Fantasy MMCLXVII - just put on your thinking cap and you're ready to go! The disadvantage of EEG is that the spatial resolution is poor. Since the electrical activity you're measuring has to get through cerebrospinal fluid, skull, and skin, it gets spread out, making it hard to tell exactly where the signals you're measuring are coming from inside the person's head.
In contrast, the technique these guys are using (which they're calling "ECoG", but most researchers will just call "intracranial EEG") records electrical activity directly from the surface of the brain. It is invasive: you need to open up a person's skull to be able to place electrodes directly on the surface of their brain. Good luck selling a videogame that lists that as a minimum system requirement! The advantage of this technique, however, is that brain activity can be much more easily localized to specific areas. So, the patterns of activity corresponding to whether a player wants their character to "move right" versus "move left" are more readily distinguished using intracranial EEG/ECoG, which means less player frustration and fewer continues needed to finally beat that annoying endboss. =)

"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. -_-

Um, citation please. Viruses can have protein components, but as far as I know their information payload is always stored as DNA or RNA.
Also, only protein -> DNA and protein -> RNA information transfers remain unknown. See reverse transcriptase and prions.

Of COURSE they're from USC. Who would come up with an attack based on hiding stuff you don't want inside stuff you want? Yup...the Trojans.

I mean, I know there tends to be some lag on Slashdot, but seriously!

Erm, given that this guy's an epilepsy patient, I'm not sure that's such a great idea =)
