Science fails to recognize the single most potent element of human existence
WH AT INTHE WORLDIS HAPPENING
man, i don’t think i’ll ever get over this picture.Someone please make this a gif with the stars moving or sparkling!!
Oh my gosh this is amazing
No one realizes that this is what the sky is supposed to look like but we fucked it up congrats earth
I think everyone knows that, pretty sure actually. Unless you’re an infant, then you’re excused
Seizure First Aid.
Learn it. Share it. Know it. Use it.
100% correct medical information on tumblr for once; also consider calling 911 if you don’t know how often the person has seizures and ESPECIALLY if the seizure has lasted 5 minutes or more (which is why the watch is critical)
This is so important!
Really good friend of mine from work back home had seizures a few times on the job. This is crucial information.
This lamp absorbs 150 times more CO2 than a tree
It’s still in the “so crazy it just might work” stage, but these microalgae-powered lamps, invented by French biochemist Pierre Calleja, could absorb a ton of carbon from the air every year. That’s as much as 150 to 200 trees. [x]
YOU DON’T UNDERSTAND. This is ingenious.
The design is a light bulb surrounded by a glass casing. The glass is filled with (water based) media and microalgae. The top is permeable to gasses so that gas exchange can occur. All of the wiring is linked to the grid underground.
Since the light source is inside, it gets scattered and “dimmed” by the water and algae. This makes it less glaringly bright and scatters the light wider, which is good for a street light. It is not longer white light as well, which helps make it easier on the eyes while still providing light.
At the same time, it provides the light for photosynthesis in the algae, so they are continuously exchanging CO2 for O2, not just in the day. It also provides a source of heat, which helps keep the algae from going dormant during cold weather (as in the snowy picture above).
And notice how I did not specify permeability - that’s because NOx’s (NO and NO2) are also permeable and can be used as nitrogen sources to microalgae. In fact, algae are relatively low maintenance. As autotrophs, they don’t require super complex media, not does it really need to be changed/added to. (I’m actually fairly certain that there would still be algae in these tanks a year later; it may need to be cleaned or something, but there would be some living algae.)
and they’re so pretty too
Are you ever super obsessed with something for a while and then it fades out into you casually liking the thing and then something triggers it and suddenly it’s back to full blown obsession
