Peer reviews. For the results to be acceptable around the scientific community, their methods and conclusions need to be validated by at least 2 other scientists familiar with that subject. Like someone said, there is axiv.org, that lets you upload your paper without this review, but it's more of a method to claim precedence if someone else publishes a similar work. It's usually not a scitation source that is taken seriously. This could, of course, be improved! There are open access journals that charge the scientists instead of the readers, but there are several scam journals popping up every day that will usually publish anything without reviews.
I am sorry about this student and what happened to them, but that's not true. The crime though (mostly mugging and pickpocketing), especially in Rio and São Paulo cities, is something to be concerned about.

Same! For me, it was an ok action/fighting movie. There is a message there, but the message itself is not as deep as people want it to be, and nothing new. It was just OK.
Also Brazil
Edit: not to mention the flash-flooding thunderstorms, tree-shattering winds, and so, so many hills.
As someone who works extensively with the spin offs instruments, I can safely say that they would be just as outraged. They are all bad quality, fail VERY frequently, and, guess what, you have to subscribe to be able to use all the features of the hardware you bought.
