Yes, but I think the article is incorrect. If you go to the site and enter your city a and destination city c you get choices of tickets a->b and b->c not a->c->b. The latter can be cancelled by the airline if you try to get a round trip. I have always thought back to back ticketing is something different where you can get a quick turn around (during the week) by buying two separate tickets that stay over the weekend. I could be wrong about that, though.

Incorrect - that's back-to-back. "Hidden City" is when you buy two (or more) separate tickets. The first one starts at the source and the last one ends at your destination. The middle destinations are your hidden cities. Amazingly, sometimes this is cheaper than one ticket. One drawback - no checked baggage (without going to pick them up outside security and then recheck the bags for the next leg).

This can't be right: let's assume half of the 78 million are outside the center 1/3 of the galaxy where gamma bathes them. The volume we are talking about is 1000ly * pi * (100k^2-33k^2) = 28e12 cubic light years of volume? So we have about 700,000ly average distance between habitable worlds?

Submission Spintronics Breakthrough. Quantum Compters Next?->

ee2go writes: An IEEE announcement states "A recent advance in the field of spintronics by researchers in Australia, the United States, and England may have edged scientists closer to a practical quantum computer. They managed to transfer data from the quantum spin of electrons onto phosphorus nuclei and store it there for nearly 2 minutes. With increased sensitivity, say observers, the technique may result in a device that serves as the readout of a quantum computer that will offer blazing speed, near-limitless memory, and virtually impenetrable defense against hacking". It will also include an RSA cracking utility for free.

Not quite. The current Indian reactors use Thorium instead of depleted Uranium to even the core temperature. Even the next generation AHWR reactor will only use Thorium as part of the fuel (from here:

In India, construction is expected to start early in the next decade on the first 300 MW(e) advanced heavy water reactor, which has been developed for co-generation applications. The reactor is designed to operate with 233U-Pu-Th fuel; it uses boiling light water as a coolant and heavy water as the moderator.
