Tomatoes that are being eaten by insects use electrical signals to send an alert to the rest of the plant, similar to the way our nervous systems warn of damage.
The messages seem to help the plant muster defences such as releasing hydrogen peroxide, a reactive chemical that combats microbial infections of damaged tissues, a study has found.
Human nervous systems use specialised cells called neurons to send electrical signals between different parts of the body. Plants lack neurons, but they do have long, thin tubes called xylem and phloem for moving sap between their roots, leaves and fruit. Charged ions flowing in and out of these tubes can propagate electrical signals around different parts of the plant in a similar way to neurons, although much less is known about the process in plants than in animals.

Pentagenella fragillima
The term “fruticose” can be confusing. You might expect a fruticose lichen to look, well, fruit like! But fruticose, at least in regard to lichens, means that it just grows in 3 dimensions--it’s not flat like leaves or crusts, as other lichens are. And while this can be confusing since all lichens grow in 3 dimensions--that’s like, our perception of reality--you can really tell what they mean when looking at the round, tubular branches of P. fragillima. This fruticose lichen has pale brown, fragile, flat or cylindrical lobes growing in tangled tufts. It either has sessile apothecia, or is sterile and produces soredia. It colonizes rocks and branches near the sea in Chile. It is very rarely found and collected, so the information on this species is extremely limited, so I am just a happy that a few pictures of it exist on the internet at all!

I havent seen anyone talk about this yet so im making a post. 
So lets say you're researching something for a paper (or just for fun) and the research paper you want to read is behind a paywall, or the site makes you create an account first, or makes you pay to download, or limits you to only 5 free articles, or otherwise makes it difficult for you to read what you want.
Tumblr media
do not fear! copy the link to the article
Tumblr media
go to sci-hub.se         (the url is always changing so its best to check out whereisscihub.now.sh to find what the current url is)
Tumblr media
slap the article link in there

bam! free access!

The fact that literal medicine is growing in our backyards and they’re classified as “weeds” annoys me so fucking much.

The fact that these are considered “weeds” upsets me to my very core.
(Yes I am aware that horsenettle is poisonous w/out the right precautions and that you can’t just EAT these plants outta the ground. The point of my post was to just point out that these plants have many medical properties that once properly identified, cleaned, and safely prepared can be used as home remedies.)
