These vegetated surfaces don’t just look pretty. They have other benefits as well, including cooling city blocks, reducing loud noises, and improving a building’s energy efficiency.What’s more, a recent modeling study shows that green walls can potentially reduce large amounts of air pollution in what’s called a “street canyon,” or the corridor between tall buildings.
For the study, Thomas Pugh, a biogeochemist at the Karlsruhe Institute of Technology in Germany, and his colleagues created a computer model of a green wall with generic vegetation in a Western European city. Then they recorded chemical reactions based on a variety of factors, such as wind speed and building placement.
The simulation revealed a clear pattern: A green wall in a street canyon trapped or absorbed large amounts of nitrogen dioxide and particulate matter—both pollutants harmful to people, said Pugh. Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.
That’s why the green-wall study is “putting forward an alternative solution that might allow [governments] to improve air quality in these problem hot spots,” he said.Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.

Ok, so I figured that perhaps not everyone is aware that this is available to use now, especially the younger folk out there.
This is OraQuick, and it is an FDA-Approved, in-home HIV test that provides results in about 20 minutes. I’m not sure about the availabilty of this product (or similar ones) in other countries, but in the U.S. you can purchase these at Walgreens for a mere 35 bucks, and you can even have them delivered to your door for complete anonymity.
Reading the results is easy. One line you are negative, two lines you are positive.
Why is this important? Well I know for a fact that a lot of guys say they are HIV negative without really getting tested, or they base that on some really old test result. There is no excuse now. You can get this in the mail if you want, and know for sure in the comfort and privacy of your own home. Its good peace of mind. And if you meet someone new and you are planning on playing around, its an easy and cheap thing to do to know where you guys stand. It builds trust right off the bat. Being safe is not just about wearing a condom. Its a combination of many things like trust, knowing the person, closeness, and being a good judge of character. Now on top of that you can keep up with your HIV status on a regular basis. :)
This is important for people to know, I never knew it existed
This is how my boyfriend and I tested before we started bareback in together after being with each other for 3 months. It’s super easy.
I know that it’s scary, believe me, I don’t practice risky behaviors and my anxiety was through the roof. It’s so important though you guys.
They even give you a non-descript bag to dispose of everything in.
I’m glad this is going around. :) Spread the word.
tbh I don’t see the fuss about having waiters/waitresses not being happy and enthusiastic like I came here to eat I didn’t come here to be amused by employees as long as I’m getting my food and they’re not being blatantly rude I don’t see why y’all need to go on yelp to rank a restaurant 0/5 and have an outburst on why your waitress didn’t smile at you when she poured you water
this is pretty fucking important
This is so cool! But what country are they from? “Africa” is really vague.
Their names are Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and Bello Eniola and they’re from Lagos, Nigeria. There’s a neat video about them here.
