pseudoscience, unability to apply the most basic self-criticism [1], and low quality papermills churning turd-ticles in action. [1] Stop reading at "Plants living near a busy road have their grow stunt because noise", that is just the dumbest explanation available in the bag. Do they noticed that those areas are typically contaminated with heavy metals?

Boquila trifoliolata appears to mimic surrounding leaves and the mechanism is currently unknown. One (controversial) hypothesis is that it has some sort of vision. https://en.m.wikipedia.org/wiki/Boquila

Paper on the experiment, where they test if the plant will mimic the leaves of an artificial plastic plant: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8903786/

Quite a read, I hope others replicate the study, because this is fascinating. If we're able to really point in the direction that the plant uses vision to mimic other plants leaves (even artificial plant), I wonder how that vision works!

Wow this is insane. I wonder if this could have real world application?

Plant-based surveillance cameras, obviously.

Just read “The Day of the Triffids” by John Wyndham (1951)[1]. It’s a great, classic horror sci-fi novel where plants can hear and talk to each other. Big influence for “Annihilation” and “28 Days Later.” Gotta love it when some crazy fictional idea turns out to have some factual (?) basis.

I think Annihilation is more a shameless remake of Stalker, as far as going into a "Zone" where an alien influence has changed the nature of reality.

The move Annihilation was based on the book of the same name (first of a trilogy):

Why the change in the title? It is not the original and there is nothing clikbaity about it. Is HN now editorializing the Economist?

The "plants don't have ears" part of the original title was, at best, unnecessarily folksy.

Guidelines say: "Otherwise please use the original title, unless it is misleading or linkbait; don't editorialize."

Similar structure, yes.

The questions about the realness of the Zone and the motives of the characters, allowed for much deeper and broader implications.

Annihilation was more specific and overlapped too much with explicit pre-existing myth(s), to be a remake of Stalker.

Ok, so I wonder if my plants would do better if I recorded jungle sounds and played them back when I'm not at home.

There were quite some experiments in that direction, but using music. I don't recall the name or have a link to such a study at hand (and I do question and never researched how scientific it was done) but the plants seemed to prefer Ravi Shankar instead of Heavy Metal.

>"This is a deeply flawed article based on a poorly designed experiment and reflects significant author bias in the interpretation of the results,” wrote Washington State University horticultural physiologist Linda Chalker-Scott in a blog post earlier this year.
