I was wrong a while ago when I said the QI podcast isn’t available through the iTunes Store. It simply doesn’t have a name that makes it obvious that it is the QI podcast: No Such Thing As A Fish.
One nice fact is that Lawrence Burst Sperry, the man who invented the aircraft autopilot, went flying in November 1916 with Mrs. Waldo Polk, whose husband was off driving an ambulance in France. They counted on the autopilot to keep them aloft, but ended up crashing naked into a bay and being found by duck hunters.
Also, if you get a zebrafish drunk and put it among sober companions, the sober ones will follow the drunk one:
Maybe something about the drunk fish’s one-on-one interactions with the other fish made the group as a whole move in the same direction. Or maybe the sober fish looked at their non-sober tankmate and saw a leader. “It is likely,” Porfiri says, that the drunk fish’s uninhibited behavior “is perceived as a boldness trait, thus imparting a high social status.” As they followed the drunk fish, the sober ones also sped up to keep pace, swimming roughly a third faster than they would have otherwise.
The very drunkest zebrafish, though, lost their leader status. Fish that had been exposed to the highest alcohol concentration began to lag behind the rest of the group, following instead of steering. Since higher alcohol doses have “sedative effects,” Porfiri says, the drunkest fish slow down and start to display “sluggishness in response to the rest of the group.”
I listed some fun facts from QI in a previous post.
