I can’t take people seriously who care about human rights but not animal rights. You’re only getting half the picture.

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.)
Traces of coca and nicotine found in Egyptian mummies - WTF fun facts
well DUH. a lot of historians are still trying to process the fact that ancient egyptians knew how to build boats, which is ridiculous. why would they not be seafarers and explorers?
this is not new or surprising information at all. it pretty much day one of any african-american studies course.
the egyptians knew that if they put their boats in front of the summer storm winds it’d blow them right across the sea to the Americas and they shared that with the greeks.
It’s really hard for people to understand that everyone had boats, exploration, and trade interactions without the same level of murder, colonization, and violence that the Europeans did. It’s really hard for people to get that.
The Sea-Craft of Prehistory (book; Eurocentric as heck)
Scientific Evidence for Pre-Columbian Transoceanic Voyages (273 pages-for the hardcore only!):The only plausible explanation for these findings is that a considerable number of transoceanic voyages in both directions across both major oceans were completed between the 7th millennium BC and the European age of discovery. Our growing knowledge of early maritime technology and its accomplishments gives us confidence that vessels and nautical skills capable of these long-distance travels were developed by the times indicated. These voyages put a new complexion on the extensive Old World/New World cultural parallels that have long been controversial.

This is my body. The temple of my creativity and spirit. It’s fat, plush, soft and contrary to popular belief, quite healthy. It allows me to touch, taste, feel, smell and experience the world around me.
This is my body.
It’s just mine.
& I fucking love it.
You are so beautiful!!!
Found in northern Africa and central and southwest Asia, sand cats are the only felid that live in sandy desert habitat. Its ears are large and set low, which helps protect it from wind-blown sand as well as improves its ability to locate prey hiding underground. Its thickly furred paws help it cope with the extremes of hot and cold sand. Indeed, the sand cat can tolerate temperatures from below freezing at 23 degrees Fereinheit to scalding days of 126 degrees Ferinheit.

Check out the site. It’s really amazing. Even giving an option to compare things to make them easier to understand. Very cool site!
