Crown shyness
- wyldfire 9y agoWhat an interesting phenomenon! Thanks for sharing.
- magic_beans 9y agoWow! The gaps look extraordinary. What a weird thing to learn about today!
- tptacek 9y agoPerhaps somebody else here listens to the Slate politics podcast, where John Dickerson this week spent 4 minutes describing this phenomenon.
- raldi 9y agoApropos of what?
- tptacek 9y agoNothing? It's just interesting to think about.

- Houshalter 9y agoThere was a bunch of popular posts about it on reddit yesterday. I would bet that is probably the most direct source of this post. Perhaps the podcast inspired the original reddit posters.
- tptacek 9y agoThat's kind of even cooler, the idea that a 4 minute bit Dickerson did about tree growth patterns could spread so virulently.
- deerpig 9y agoI heard it on the Gabfest before seeing it here as well.

- raldi 9y agoWhat does reaction wood have to do with growing plants indoors?
- adventured 9y agoThere's typically no wind indoors. http://awesci.com/the-role-of-wind-in-a-trees-life/ http://awesci.com/the-role-of-wind-in-a-trees-life/
- nayuki 9y agoYou could say that you go down a tree of exploration on Wikipedia. https://xkcd.com/214/ https://xkcd.com/214/
- mrout 9y agoWhy is Wikipedia incapable of seeing that I'm on a desktop computer from my User-Agent and redirecting me to the desktop site? Gah!
- colordrops 9y agoNot sure why but this phenomenon is extremely pronounced while tripping on LSD.

- Mz 9y agoThey also can "scream" by giving off a pulse (that humans can't hear) when attacked and can "talk" to each other by giving off chemicals when attacked by insects, thereby warning neighboring relatives to start creating protective chemicals to defend themselves.
- wybiral 9y agoI will never again feel safe in the woods.
- Mz 9y agoI stopped obsessing about the supposed morality of eating meat after I learned these things. Just because you can't hear your veggies scream doesn't mean they aren't suffering. (There are lots of really good reasons to limit meat consumption. But, the touchy-feely appeal to "think about the suffering of the animals" is species-ist (for lack of a better word).)
- ocb 9y agoThis is getting very off topic, but I think that's a terrible basis for disregarding the ethical argument against eating meat. Why is it "species-ist" to think that mammals and other animals with highly developed nervous systems might have a conscious experience similar to our own (and not plants)?

- donatj 9y agoThis is super interesting. This is the kind of thing I enjoy on HN most, oddly.
- zone411 9y agoYou might want to check out "The Hidden Life of Trees: What They Feel, How They Communicate" by Peter Wohlleben. It's an enjoyable book that covers similar topics, also available as an audiobook.
