I reblog stuff here.

Take a moment and ask yourself, a project like this requires a lot of time, money and dedication of resources, why would scientists dedicate that time to something that could just be done by a tree?

The answer is they wouldn't. So that means this claim requires further investigation!

This project is called LIQUID 3, and it's not meant for cities with wide open spaces, it's meant for cities like Belgrade in Serbia. These cities are densely populated and heavily polluted, to the point where pollution actually chokes out current trees and makes creating green spaces difficult.

Liquid 3 was a PhD scientists answer to these problems. The microalgae tank is intended for spaces where you either:

Don't have enough space to plant full trees, or

Don't have enough time to plant trees and wait for them to grow up.

The tank is extremely efficient when you consider the amount of space needed compared to the amount of CO2 turned into oxygen. The tank can operate throughout the winter. And most importantly, it can be quickly set up in areas that desperately need relief from air pollution NOW not in 10 years when trees are done growing. Children currently suffocating on polluted air can't wait for trees to grow, they need to be taken care of now, and Liquid 3 is one of the ways to take care of them. Depending on the species of microalgea used, a number have shown a pretty amazing capacity to pull heavy metals out of the air which is something trees can get choked up by.

The tanks aren't just tanks either! Liquid 3 have solar panels placed on top, they have lighting and mobile phone charging, and they work as public benches. The designers of it want to encourage green spaces where there's room, but where there isn't room or time, Liquid 3 can step in. Realistically, this isn't a replacement for trees. It's replacing boring metal city benches with new, cooler benches that also clean the air (and have at least some heating during the winter).

Not only that, but the microalgea that grows is native to Serbia and all that microalgea has a ton of great uses! It makes for great fertilizer, compost, wastewater treatment, cleaner biofuels and even for helping create new tanks for further air purification. They only require a quick algae divide once a month, and the produced algae can be carted off to where ever it's needed. This makes them effective solutions for areas that can't sustain complex installations.

A good video that accurately explains why stud is a term used for black lesbians only, not white, not poc, BLACK

the person in the video is a fem presenting black person in their car. they say “i love that you asked, lemme give you a little history lesson. full disclaimer, no hate to the commenter, i’m just giving everybody a bit of a debrief! now firstly, let’s talk about where the term stud actually comes from.

back in the days of slavery, when people still used to refer to us as animals, black people that were taller were known to be stronger because they could do more work. so down in the south, they started comparing us to horses. that then coined the term[s] studs for men, and stallions for females. like megan thee stallion. it was really big in the south. to compare us to animals.

but enough about the bleach brigade, let’s actually get back into the history. as you know, or if you don’t know, black women were not able to enter the working class until well into the 1960s. before then, there was a small populous of women that were still working, even though they technically were not supposed to.

‘how was it possible?’ these women would be dressing more masculine—using binders in order to help put down their chests, dressing more in a male form—and because of the fact that most bleach bandits believed that we, as black women, were already masculine, they got away with it. thus coining the term, in the black community, “stud.” because all the dudes knew, but she was one of the guys. so what did it matter?

any time the chlorine community would come up to black people and be like “hey! is that a female working!?” the guys would just save her and be like ‘nah, that’s a stud right there.” it was joke to them because they all knew. but as times changed and slang did too, the black community still keeps it close at heart. and yes, it was rooted in racism, but we’re taking it back for ourselves.

New from JSTOR Daily: Meet Rollerena, New York City’s roller-skating Fairy Godmother!

In flowing gowns, vintage skates, rhinestoned glasses, and elaborate hats, Rollerena became a beloved presence in queer New York. She appeared at Pride marches and legendary nightclubs, using performance to create joy and make queer life more visible in public. During the AIDS crisis, Rollerena became an ACT UP activist and helped rally her community around creative expression and collective action. A newly digitized archive from Reveal Digital preserves the flyers, photographs, speeches, and collages that document her remarkable public life.

Read Emilie Hardman’s story about a queer icon who understood the political power of being seen.

You’ve heard of employee unions using collective bargaining to force the bosses to provide better pay and better working condiditions. But did you know if you rent an apartment in an apartment complex, you can do something similar?

It’s called a Tenant Association, and it’s basically a union for renters.

Here’s an overview of the why and how of forming a tenant association

Here’s a more thorough organizing manual

I hate how every time somebody makes an acoustic cover of a rap song, y'all be in the comments like "Wait guys, why are the lyrics actually kinda deep?" Duh! Of course the lyrics are deep. The problem is, some of y'all have a bias so deeply entrenched that you can't possibly fathom the fact that Black music can be deep, can be introspective, can be intellectual. Y'all turn on Vaughn and Durk and YoungBoy thinking like, "Ay, whoopty-woo, it's just a little hood jam." No, these - Yes, yes the songs are fun, I'll admit that, but these songs are talking about real life stuff. They're talking about losing people to gun violence. They're talking about substance abuse. They're talking about growing up in poverty. But again, unfortunately, the contributions that Black people make to art in this country are so commonly disrespected and invalidated to the point where y'all only ever appreciate rap when it's made palatable. When it's turned into an acoustic cover!
