The Surveillance State

   2019    Technology
Frequent security expos feature companies like Megvii and its facial- recognition technology. They show off cameras with A.I. that can track cars, and identify individuals by face, or just by the way they walk. In China it's been projected that over 600 million cameras will be deployed by 2020. Here, they may be used to discourage jaywalking, but they also serve to remind people that the state is watching. Matching with the most advanced artificial intelligence algorithm, they can actually use this data, real-time data, to pick up a face or pick up a action.
A.I. is a technology that can be used for good and for evil. So, how do governments limit themselves in, on the one hand, using this A.I. technology and the database to maintain a safe environment for its citizens, but not to encroach on a individual's rights and privacies?

Isolation

   2017    Medicine
Your brain is like a hungry sponge. It's constantly absorbing information. It thrives when stimulated. Between smartphones and books, and movies, and friends and family, thousands of sensations are constantly going into our heads. But what if it all got cut off?. Imagine being confined to a 10-by-10-foot room in complete isolation. No timekeeping devices, no phones, no books, nothing to write on, no windows. Psychologists say that fewer than three days in a room like this can lead to brain damage. I will be staying in this room for three days.
Michael explores the effects of isolation on the human mind by subjecting himself to a very interesting experiment.

The Internet Whisperers

   2018    Medicine
In the Youtube video galaxy a new star has been born: the ASMR videos. It stands for Autonomous Sensory Meridian Response, and refers to the pleasant feeling that users associate with this type of digital content. The physical reaction also changes significantly from individual to individual and people reportedly experience a pleasant feeling of tingling in the scalp, which can spread to the shoulders and back, and usually be accompanied by a feeling of relaxation and generalised well-being. The intensity of the response can also be very strong, so much so that some have used the word 'braingasm', literally 'brain orgasm' to express the feeling.
It's likely that you've already heard about it, but if not, this is the perfect opportunity to learn more about it. Especially because, for the first time, it seems that the benefits of ASMR videos have been scientifically proven.
