I thought this article was very well written because at first it has a nice captivating introduction and title. The author goes on to explain the concepts in the most technical manner, but then he takes a step back and goes back to the reader's level in order to facilitate the reader's understanding if he or she does not have much knowledge on the topic. All in all, the article introduced a very interesting discovery about human evolution.

Researchers at Georgia Tech are currently focusing on using gait recognition to identify people. What is useful about this is that people do not need to be enrolled in a database in order to recognize them.

I found this interesting because it mentions the fact that there may have been a revision to the Beale cipher before it was published.

Although it doesn't directly deal with online privacy, I thought this was really cool. It is a new form of encryption involving sending a beam of two photons with only one of them acting as a "key." It could very well be the new method of securing privacy.

With the shutdown of the silk road, the NSA has proven that it is monitoring even the most anonymous parts of the web. This raises some serious questions. Is anything that we do online really "private?"
