Experiments show that what the algorithm picks to show you can affect your emotions. But that’s not all. It also affects political behavior.

TEDMED – One more reason to get a good night’s sleep
StandardResearch paper: Sleep Drives Metabolite Clearance from the Adult Brain, DOI: 10.1126/science.1241224
Important points:
- Brain has no lymphatic system to clean it
- During sleep brain cells seem to shrink
- Cerebrospinal fluid (CSF) acts as a detoxing agent removing toxins built up while the brain is conscious.
- CSF influx only happens during sleep. It is inhibited during wakefulness.
and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing [cerebrospinal fluid – CSF] fluid to rush through and allowing waste to be cleared out.
But our most surprising finding was that all of this, everything I just told you about, with all this fluid rushing through the brain, it’s only happening in the sleeping brain.
Visualized statistical history of the world (BBC Four & TED)
StandardToday I share two videos with you. The first is an episode of BBC Four’s “The Joy of Stats”. The other is a TED talk.
Both are presented by Hans Rosling.
In these videos Hans Rosling visually demonstrates statistical data on the world’s wealth, health, family size, & daily income among several others by continent and country. The demonstrations are amazing. Enjoy
