“Our social tools are not an improvement to modern society, they are a challenge to it”*…

 

The limbic system is the center for pleasure and addiction in the rodent nervous system. In a controlled study on adolescent rats, scientists sought to determine whether or not the levels of dopamine, the “feel good” neurotransmitter, could be maintained in this region over prolonged social media use. With a series of topical content posts, evergreen posts, and meme dissemination, scientists were able to gauge whether or not the “thrill” derived from getting likes, favorites, or retweets was sustainable over a finite period of time…

Rats that only ever received 20-30 likes after sharing a “well-rounded” think piece would enjoy an extremely high level of dopamine if they broke 50 likes on an unexpected political rant declaring that “Trump had finally gone too far.” But, when the same rat racked up similar numbers by acknowledging that his news feed was a “political echo chamber,” activity in this region of the brain slowed down once again…

In short, social media does not prove to be a sustainable source of cognitive reward…

Read the all-too-painfully-relevant “results” in full at Adam Rotstein‘s “Regulation of Dopamine During Social Media Use in Adolescent Rats.”

As we burst bubbles, we might recall that it was on this date in 2000 that the nuclear generating facility at Chernobyl in the Ukraine, was (finally) shut down.  14 years earlier, it had been the site of the worst nuclear power plant accident in history (in terms of cost and casualties), one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale, the other being the Fukushima Daiichi nuclear disaster in Japan in 2011.  On April 26, 1986, Reactor #4 exploded, creating massive damage in site and releasing 9 days of radioactive plumes that spread over Europe and the USSR.  Two were killed in the explosion; 29 died in the immediate aftermath (of acute radiation poisoning).  The remains of Reactor #4 were enclosed in a massive “sarcophagus,” and the other three reactors were returned to service.  One by one, they failed.  The decommissioning held on this date in 2000 was ceremonial.  Reactor #3, the last one standing, had in fact been shut down the previous week because of technical problems. It was restarted– unattached to the national grid and at minimum power output– so that the world would be able to see it symbolically switched off.
