Fermentation, like canning and freezing, is a very cool way to preserve seasonal produce. And, if you’ve never had homemade Korean fermented veggies… you’re missing out. 😋 Traditional fermented German sauerkraut is still on my foods to try list.

Reading up on trap crops. I've always heard about using plants like marigold to repel pests, but this is the idea that you plant pest sensitive crops to either divert pests away from your main crop, or plant the sensitive crop off-season to stop the pests's life cycle. Cool. #sustainablescience

I just want to say, peptide stacks ... the peptide part is basically short for peptide growth hormone. Same for synthetic peptides -- they are synthetic peptide growth hormones. I'm not saying don't take them if the doctor says to... I'm just thinking maybe don't recommend them to high schoolers?

I love biochemistry around fermentation, so this paper was fun for me. They did a Genome Wide Association with 143 plants, 2 species of coffee to look for flavor genes, and the core of their study found that more sugar makes coffee taste better. ❤️❤️❤️

Chimeric autoantibody receptor (CAAR) T cells are showing promise in treating autoimmune disorders. Basically, the patient's T-cells are genetically modified to attack the disease causing B cells which are attacking the healthy body tissues - 'resetting/calming' the immune system. #sharegoodnewstoo

Plant‐microbial fuel cells (PMFCs) are a cool concept - harnessing the transferal of electrons that all organisms do at some level. The plants help provide the sugar (and other metabolic products) while the battery harnesses the energy bacteria produce breaking the products down.

One of the fun things about plants is their chemicals. For instance pelargonic acid was IDed in Pelargonium. It’s a medium chain, saturated fatty acid used as a mild herbicide because it can disrupt cell membranes (like soap) but like most fatty acids, it breaks down quickly in the environment.
