00:00Venus flytraps are one of nature's most interesting plants, as they're one of the few that's carnivorous, meaning they actually eat living creatures.
00:11However, despite being, well, plants, the mechanisms of their electrically activated jaws were never quite understood.
00:17That is, until now.
00:18Researchers from Linköping University in Sweden say that it was only a few years ago that botanists were able to figure out what instigated the closing of a Venus flytraps' jaws.
00:27That is, two sequential strokes of highly sensitive hairs within its mouth, which causes an influx of charged calcium ions to close the fanged plant's jaws.
00:35However, this was only the first step, with this new study mapping the precise propagation of those signals.
00:40The charged calcium ions create what's called an action potential.
00:43And even though plants don't have a nervous system like us, this action potential causes similar reactions in the plant nonetheless.
00:49So researchers used electrodes that could cover much of the plant's lobes, or what make up its carnivorous head.
00:54Finding that if the sensory hairs were touched twice within 30 seconds, they would snap shut on the second encounter.
01:00And those signals would radiate at a constant speed.
01:02However, if they were touched with more than a minute in between, the electrical signal would move faster on the second encounter.
01:08Meaning, it appears that the plant was more aware.
01:10Almost as if the Venus flytrap was on guard.
01:13It appears on guard.

01:22This place is not as if the Venus fly is on guard.
01:23Geoff is on guard.
01:25Just like that, maybe it's a Hell.
01:27It appears that that the Campbell's broadcaster will switch away from the ast pessoless Jedi Academy.
01:29Check out that the тому story might have been decreased in our bill.
