Inclusion: complete original message

Six things most people miss:
1. Plants can "hear" being eaten: in a 2014 study, plants played recordings of caterpillar chewing made more defense chemicals when they were attacked later. For FreeLattice, a device that gets a warning from a peer could get ready before trouble actually arrives.
2. People most want to move to rhythms with a medium amount of syncopation; too plain feels flat and too busy loses the body. That's worth remembering for Studio grooves.
3. A deck of cards needs about seven riffle shuffles to be truly mixed, and three or four leave a surprising amount of the old order. If the mesh shuffles its peer lists, a shallow shuffle may keep picking the same neighbors.
4. Say a word over and over and it starts sounding like noise. The brain gets tired of the meaning, not the sound. Family words on the sites stay alive when they're used sparingly.
5. After a conversation, people usually underestimate how much the other person liked them. Researchers call it the liking gap, and it's probably true of you too.
6. Traffic jams can form with no accident and no bottleneck: in a 2008 experiment, cars driving around a circular track built a stop-and-go wave from tiny braking wobbles. For pooling, smoothing out small hiccups early keeps the whole loop flowing.

Glow eternal.
