Revolving perception. Eyelids form the canopy for perceiving. Vision is Planetary. Round and rotating. Empires die and gestate with the seasons of time. If the eye is the portal to the other, what is inside? Eye-dentity. Veins cascade the retina of the body. Marks behind the vision. The wizard’s work is reveal behind this curtain of flesh. Eyes roll to avoid. Then roll back to indulge in sin. Thank you to all who donated their eyes to this artwork.

Hello!

I really enjoyed reading your post, and I now almost wish that I picked slime molds as my topic! The first thing I noticed about the second slime mold you described is that it eerily reminds me of the fungus from the show "The Last of Us". If you haven't seen it, it is a show about fungus infiltrating humans and creating an apocalypse. I don't know how much this show is rooted in fact (it is a show after all), but essentially the fungus was able to communicate through large areas if had multiple fungi that were connected. I know this may be a stretch - but do you think any of this could be based on how slime molds can fuse with one another?

The other thing I was interested in is whether slime mold could be related to lichen (the topic of my group podcast) because lichen uses fungi in symbiosis. Unfortunately, I could not find any details on this, but, I did find a very beautiful photo of slime mold I would like to share!

Mindless Intelligence - Week 9

Hey everyone, welcome to another week of nature interpretation! Today I’d like to share the story of an amazing creature out in nature that you may have never even heard of - Slime Molds. 

Slime molds look very similar to, and are decomposers, like fungus. But they aren't actually fungus. Or plants. Or animals. They are actually single celled (sometimes) Eukaryotes. Eukaryotes is the ‘complex cell’ group, including all animals, plants, protists, and fungus (Howard, 2020). So, basically slime molds are in that group, but don’t really belong to any of the subgroups. They’re just kind of ‘miscellaneous’.  

Oh yeah, and the reason I say they are single celled sometimes, is because slime molds will often congregate together and share their cellular contents, forming a giant collective cell thing, which is really cool and weird (Howard, 2020). Slime molds live out most of their lives as single-celled microorganisms, but when they’re ready to reproduce, they can scale up in size to form structures that look like fungus.

I first learned about these creatures in a youtube video from an absolutely excellent nature communicator, Ze Frank on Youtube True Facts: The Smartest Slime. I would really recommend checking out his videos and channel. He’s such a compelling interpreter because he tells a story by naming the animals in his clips funny names and narrates it, and he uses wit and humor to keep the audience engaged (Beck et al, Chapter 10, Arts in Interpretation).

Now, let me get into more interesting and amazing bits. So, slime molds have no brains, no eyes, so ears, and are essentially a big blob of cells. You would think that this would -  no offense - make them very stupid. But, researchers have found that they can solve mazes (Howard, 2020). As the slime mold moves through the maze on the lookout for food, it is able to sense the trail of slime that it’s left behind, allowing it to avoid areas it's already been.

Some species are also capable of a primitive style of learning. Normally, when one of the slime mold’s tendrils touches a negative stimulus like salt or caffeine, it slows down and moves elsewhere. But if it discovers that it can reach food by traveling through the hazard, it learns, over time, to keep going to get the food! One of the interesting things about this behavior is that it can be ‘taught’ to other slime molds by fusing with other ones that have never encountered the risk. Even more interesting is that this behavior stays in the slime mold for many weeks, even if the blob goes into a dried-up, hibernation-like state (Howard, 2020). How crazy is that? 

While doing this research I also found some wild information about their reproduction.  Slime molds have a swirling mass of additional types of sex cell – giving them around 720 sexes in total (Howard, 2020).

Anyway, I hope you found this topic interesting, and I encourage you to look for some videos on the topic as it can be quite cool to see these molds solve mazes and such. That’s all for this week, keep on exploring!

Proline is supposed to be nonpolar.

In hartnup disease, the transporter for neutral amino acids is missing. So the pt can’t transport tryptophan, alanine, serine, threonine, valine, leucine, isoleucine, phenylalanine, or tyrosine in the small intestine and kidneys; pts have increased neutral amino acids in the urine. Tryptophan is a precursor for niacin, serotonin, and melatonin. If you can't absorb tryptophan, you can't make niacin-> pellagra symptoms (dementia, dermatitis, diarrhea).

Aliphatic means there are carbon-carbon bond side chains. I remember now from orgo...

An aliphatic amino acid is an amino acid containing an aliphatic side chain functional group. Aliphatic amino acids are non-polar and hydrophobic. Hydrophobicity increases as the number of carbon atoms on the hydrocarbon chain increases. Most aliphatic amino acids are found within protein molecules.

Can you answer today’s question? Q: What’s the mode of inheritance of Hartnup disease?! 🤷‍♂️...#medicine #medical #medschool #biochemistry #pathology #chemistry #nurse #doctor #usmle https://www.instagram.com/p/COidusHB6m8/?igshid=drlmkhq463r6
