things i've heard environmental science majors say:

"For the test we'll need to tell the different flavours of mayflies apart." / "Did you just say flavours?"

"It amazes me how many city kids are in this program." / "We're all desperate to get out of this city."

"I think everyone who attended all the surface water pollution lab sections should be allowed to lick one piece of glassware of their choosing. Y'know, as a treat."

"Professor, nobody goes into this major unless they like to eat dirt." / "Great, so you can talk the Students' Association into convincing the board to give me funding for my trees?"

"What're we toasting to?" / "Nitrogen pollution."

"You look frustrated. What's up?" / "I had twenty-one Leptophlebiidae in my dish. He's going to think I'm lying about how many Leptophlebiidae are in my dish."

"If you weren't raised by Wall-E, do you even belong in this class?" / "The Onceler." / "Fuck, good point."

"Dude, I spent the whole exam trying not to sink my teeth into a really, really juicy bug in my sample—" / "Cranefly?" / "...yeah."

"Well, just make sure you're not (person)'s lab partner. Last weekend's trip involved him leaving too many fish in the dirt for the professor's liking."

[exhausted chorus] "And the fish go belly-up."

"What's the major difference between east coast and west coast soils?" / "Alcoholism."

"Got any plans for the holidays?" / "Gonna go home and listen to my entire extended family call me a tree-hugging hippie." / "Aren't we all?"

OKAY THIS ARTICLE IS SO COOL

I'm going to try to explain this in a comprehensible way, because honestly it's wild to wrap your head around even for me, who has a degree in chemistry. But bear with me.

Okay, so. Solids, right? They are rigid enough to hold their shape, but aside from that they are quite variable. Some solids are hard, others are soft, some are brittle or rubbery or malleable. So what determines these qualities? And what creates the rigid structure that makes a solid a solid? Most people would tell you that it depends on the atoms that make up the solid, and the bonds between those atoms. Rubber is flexible because of the polymers it's made of, steel is strong because of the metallic bonds between its atoms. And this applies to all solids. Or so everybody thought.

A paper published in the journal Nature has discovered that biological materials such as wood, fungi, cotton, hair, and anything else that can respond to the humidity in the environment may be composed of a new class of matter dubbed "hydration solids". That's because the rigidity and solidness of the materials doesn't actually come from the atoms and bonds, but from the water molecules hanging out in between.

So basically, try to imagine a hydration solid as a bunch of balloons taped together to form a giant cube, with the actual balloon part representing the atoms and bonds of the material, and the air filling the balloons as the water in the pores of the solid. What makes this "solid" cube shaped? It's not because of the rubber at all, but the air inside. If you took out all the air from inside the balloons, the structure wouldn't be able to hold its shape.

Ozger Sahin, one of the paper's authors, said

"When we take a walk in the woods, we think of the trees and plants around us as typical solids. This research shows that we should really think of those trees and plants as towers of water holding sugars and proteins in place. It's really water's world."

And the great thing about this discovery (and one of the reasons to support its validity) is that thinking about hydration solids this way makes the math so so so much easier. Before this, if you wanted to calculate how water interacts with organic matter, you would need advanced computer simulations. Now, there are simple equations that you can do in your head. Being able to calculate a material's properties using basic physics principles is a really big deal, because so far we have only been able to do that with gasses (PV=nRT anyone?). Expanding that to a group that encompasses 50-90% of the biological world around us is huge.

Romantic academia:

Going on study dates to pretty libraries, fighting to find a seat next to each other.

On discord listening to them go through a powerpoint the night before their big presentation.

The Arts/Humanities one proof-reading the STEM one's motivation letters/long emails.

Reading through interesting research in bed together, sharing the one phone screen.

Alternating between who is the one making tea for the study session. (Bonus: matching study mugs)

Study breaks include marveling over some super niche knowledge acquired during the study session.

Emailing an article as a pdf, and titling the email "I thought you'd find this interesting :-)"

Setting a timer for a cuddle break when the assignment work gets too overwhelming. Celebrating together when the assignment gets done.

Sharing the excitement of finding a new productivity app / stationary shop / study hack.

It's so funny to me that people think of Math/Mathematicians as being hyper-logical and rational. Like, have you seen some of the wild things hiding in the Math?

Did you know there are non-computable numbers?? (https://en.wikipedia.org/wiki/Chaitin%27s_constant)

Did you know that there are things that are true, but we can't prove them??? (https://en.wikipedia.org/wiki/G%C3%B6del%27s_incompleteness_theorems)

Did you know that we can prove that something exists, and yet never actually figure out what that thing is?? (https://mathworld.wolfram.com/NonconstructiveProof.html)

Math is crazy. Math is wild. Math hardly makes sense, and when you think you understand the weirdest parts of it, everyone who hears you explain it to thinks you're a gibbering lunatic.

"In mathematics you don’t understand things. You just get used to them." - von Neumann

(please share more unhinged math with me, i want to see more scary math)

why neuroscience is cool

space & the brain are like the two final frontiers

we know just enough to know we know nothing

there are radically new theories all. the. time. and even just in my research assistant work i've been able to meet with, talk to, and work with the people making them

it's such a philosophical science

potential to do a lot of good in fighting neurological diseases

things like BCI (brain computer interface) and OI (organoid intelligence) are soooooo new and anyone's game - motivation to study hard and be successful so i can take back my field from elon musk

machine learning is going to rapidly increase neuroscience progress i promise you. we get so caught up in AI stealing jobs but yes please steal my job of manually analyzing fMRI scans please i would much prefer to work on the science PLUS computational simulations will soon >>> animal testing to make all drug testing safer and more ethical !! we love ethical AI <3

collab with...everyone under the sun - psychologists, philosophers, ethicists, physicists, molecular biologists, chemists, drug development, machine learning, traditional computing, business, history, education, literally try to name a field we don't work with

it's the brain eeeeee

did you find ulric?

i'm so flattered that a small corner of the internet remembers ulric -- yes! i did find him, he is safe & will be featured in my mid-week post on wednesday. i'll relay the concern to him.

24/03/24 || Sunday

I got a summer internship! And at such a wonderful time, too. Recently I had been feeling so overwhelmingly stupid, cause my grades don't seem to want to go up, and I had lost all motivation to do work. But with the conference and this internship, my passion for research is back up again, and I am so glad!

With the fast fashion industry… how it is… finding sustainable ways to make fabric is super important. Fibers from synthetic fabrics make up 35% of the microplastics that make their way to the ocean. Natural fibers sourced from plants or animals are much more environmentally sound options, including silk.

Currently, the only way to get natural silk on a large scale is to harvest it from silkworms. You’ve probably heard about the strength and durability of spider silk (it is 6x stronger than Kevlar!) but as of yet there hasn’t been a good way of getting it. Raising spiders the way people do silkworms isn’t really an option. Spiders need a lot of room to build their webs compared to silkworms, and individual spiders don’t produce that much silk. Plus, when you put a whole bunch of spiders in captivity together, they tend to start eating each other.

Attempts to artificially recreate spider silk have also been less than successful. Spider silk has a surface layer of glycoproteins and lipids on it that works as a sort of anti-aging “skin”- allowing the silk to withstand conditions such as sunlight and humidity. But this layer has been very tricky to reproduce.

However, as scientists in China realized, silkworms produce that same kind of layer on their silk. So what if we just genetically modified silkworms to produce spider silk?

That is exactly what the researchers at Donghua University in Shanghai did. A team of researchers introduced spider silk protein genes to silkworms using CRISPR-Cas9 gene editing and microinjections in silkworm eggs. In addition to this, they altered the spider silk proteins so that they would interact properly with the other proteins in silkworm glands. And it worked! This is the first study ever to produce full length spider silk proteins from silkworms.

The applications of this are incredibly exciting. In addition to producing comfortable textiles and new, innovative bulletproof vests, silkworm generated spider silk could be used in cutting edge smart materials or even just to create better performing sutures. In the future, this team intends to research how to modify this new spider silk to be even stronger, and they are confident that “large-scale commercialization is on the horizon."
