Vegans aren't going to have anything to eat now... /s In all seriousness, this is wild.

What's wild about it? Plants shrink when drying up and that collapses tiny cavities in their stems. It's only surprising that this sound can be detected so easily.

If you camp in spring near fast growing grasses or bushes, you can clearly hear them grow.

Informative here meaning that you can deduce something about a plant's condition from faint sounds emitted by it. It's not implying that the plants use those sounds for the purpose of transmitting information. From the article: "These results demonstrate the potential in studying plant bioacoustics, suggest that plant acoustic emissions may play an important role in ecology and evolution, and may have direct implicat…

Earlier quoted context omitted.

So true, this has become one of my mantras.

How do you mentally frame it. Like "ignorance is acceptable" or "we are limited beings" I think as long as we are within the realm of reality, no single person or species can know everything so we need to accept contextual knowledge will be out limitation. I often wonder to what level will we need to know someone to be able to satisfy abstract statements.

you'll never run out of amazing things to learn

A pig's squeals when it's slaughtered is merely air passing through the constricted trachea.

How do you know what you are hearing is them “growing” instead of wind rustling them or insects moving around?
