I highly recommend to the authors a simple experiment:

1. Set up your ultrasound detection system in the usual way.

2. Take the audio output of that system and down-convert it to frequencies in the normal human hearing range.

3. Make a YouTube video of this and then call me back.

I would put the experiment inside an EMI/RFI chamber so that no outside interference could be detected................

Not screaming but changes to the electrical makeup of the surface of the plant.

One of the shrimp was heard to say that the water seemed a little warm even for them. /s

Awesome! Thanks for sharing. I remember those ads in magazines many decades ago.

Looks like vegans have a choice to make. Starve to death or, um. OK, starve to death

Veganism is so stupid.
The human body NEEDS proteins and fats, and not just from plants.

Many vegans have killed their own children by forcing them to be vegan at infancy...............

“I didn’t need a study to know about this. Every time I cut down a multiflora rose, another multiflora branch grabs and stabs me. EVERY time. Same with burdock. Cut one and another grabs ahold.”

My grandfather planted that scourge all over our farm property at the advice of the DNR. His later opinion of what they could do with it is unprintable. Crossbow herbicide works wonders on it, sumac, and poison ivy. No harm to grass.

You reminded me of recordings of deer mice, made by a scientist studying the use of ultrasound by animals. The mice ‘sing’ above the range where humans can hear (though some people have claimed to hear them, including the naturalist and writer Sally Carrighar) and the recordings have to be slowed-down for the human ear to perceive the sounds:

So when a Vegan pulls a plant out of the ground will he/she hear the plants pitiful last cry?

Will the said Vegan have an emotional meltdown knowing that they caused a plant “pain?”
