The professor mentioned a test bank and then later proceeded to mention the publishing companies of certain textbooks used by the department and the university in general - these test banks are sometimes floating around the internet, on amazon.com, etc. Some publishers put out CD test banks and others only make them available online. Either way, they're in a handily spreadable digital format. However, apparently whoever got a hold of that test bank was not discreet in with whom she/he was sharing it (my guess). And since so many apparently had the test bank, it gives me the impression someone might have been selling it (otherwise, why give it away to so many students). I've always assumed any exam could be thrown out at any university, in any class, if there were a large number of people cheating at any given time on a given exam.

So now everyone who works at one of these airports with body scanners needs to be scanned themselves. Every time they leave and reenter a secured area. Everyday they show up for work. I hope their insurance covers repeated exposure to low-level backscatter x-rays.

after all, it's been around likely over 120,000 years. I work at a science research institution in DC where several people have been researching e coli at high pressure and standard atp. Yes, Virginia, there is life at 5 GPa. And beyond. I'm amazed how these microbe survive for years at depths and pressures far below what many people think of as a high pressure regime. It almost makes all the Lost City studies rather silly when researchers make claims about life at the bottom of a 7 mile deep trench.
