Project Envisions Modular Aircraft That Double as Train Cars
The article focuses on the technical aspects: can it be done. Yes, I'm sure it can be done. But that wouldn't suddenly turn air travel into rail travel.
Think on the differences here for a bit. Air travel security is very tight because of the security risks. As much as some may call it security theater, there are real risks with getting that many people together on an airplane loaded with fuel which can go anywhere. This proposal does nothing to mitigate those security issues, so none of those security precautions common in airports would likely change.
Private Networks For Public Safety
"There should be easy practices for anyone to open up an otherwise-closed Wi-Fi access point if it's still connected to broadband and is near people in trouble"
That sounds like an open invitation for every hacker in the world to open up any Wi-Fi access point. How can you guarantee that such a capability wouldn't be abused?
Study: Online Social Influence Has the Strongest Effect On Voting Behavior
The conclusion is pure conjecture. There is no time dimension in their analysis. This shows that people who saw Facebook pictures of friends who voted are slightly more likely to admit that they also voted. To prove that the Facebook pictures actually influenced whether people voted the study would have to know the time people saw the Facebook message AND the time they voted to know whether the person voted before or after seeing the message. They couldn't have gotten that information from voting rolls.
Interpreting the results leaves no clear causal conclusions. It just opens the door for more studies to find more information.

This was old news from a couple days ago, covered on some respectable media outlets
Will Tabbed Windows Be the Next Big Thing?
Wait, so you are talking adding something so that I need to think about how I want to organize the applications I have open? How would that be improving my productivity? Things improve my productivity if they reduce or eliminate the amount of thought or effort I have to put into a task. I'm not sure I see how this would do that any better than the Winblows Taskbar.
Computer DJ Uses Biofeedback to Mix
Macross Plus? The people at the Sharon Apple (virtuoid idol) concerts were fitted with bracelets that monitored everyone's vitals. The computer people modified the music and lighting to control everyone's mood. By the end of the movie Sharon Apple was able to sorta do mind control on people. This is what I wanna see next time I go to a concert!
