This miniature ecosystem has been thriving in an almost completely isolated state for more than forty years. It has been watered just once in that time.The original single spiderwort plant has grown and multiplied, putting out seedlings. As it has access to light, it continues to photosynthesize. The water builds up on the inside of the bottle and then rains back down on the plants in a miniature version of the water cycle.
As leaves die, they fall off and rot at the bottom producing the carbon dioxide and nutrients required for more plants to grow.

if you don’t think this is fucking rad then get out of my face

New science print but this time I zoomed into cellular anatomy. Imagine this little guy  wiggling his way throughout your entire body.  Whether you love science or you know a little scientist to be, this poster is a cute and informative way to learn about the the smallest unit of life: The cell!

The Physics of Curling

I had no idea that the physics of curling was so complicated, controversial, and downright fascinating. Of course, Destin would be the one to show us that, right?

Check it out Smarter Every Day on YouTube (if for some reason there are a few of you out there that haven’t yet, which would be hard for me to believe)

Check out the Latest Smarter Every Day video!  Here’s a blurb on it from Joe Hanson from the itsokaytobesmart blog.  Also, this video is the announcement of the Smarter Every Day Patreon and Subbable campaigns!

http://www.patreon.com/creation?hid=286815

I hope everyone will consider supporting Destin’s channel on Patreon or Subbable.

It makes me so happy that smart folks are developing smart ways to help other smart folks fund their smart and creative projects. Kudos to the folks at Subbable and Patreon.

Oh, and I don’t want to give away the video, but my guess on the competing theories of curling physics is that, like most science, the answer will end up somewhere in the middle (near the button).

That seems to be just how science works, no?

And I guess if that doesn’t do the trick, we could have the competing labs face off in a science curling battle.

Endangered Tortoises Are Being Defaced on Purpose… to Protect Them

by Sabrina Elfarra

Some of the rarest tortoises in the world are a hot commodity on the black market for their unique golden shells which can sell for tens of thousands of dollars.

In an effort to obstruct poachers, conservationists have made the bold move to carve into the shells of the tortoises, protecting the animals by making their domes less attractive.  The branded shells also make it easier for authorities to trace them if they are stolen.

“Endangered tortoises and turtles are facing a real threat, and we’re hoping that this will be an effective tool to keep them safe,” Eric Goode, the founder and president of the Turtle Conservancy told ABC News today.

Years of hunting have caused near extinction for many tortoise species, so sanctuaries and zoos are using identification marks, including laser inscribing, tattoos and engraving to hinder poachers and discourage collectors from paying a great deal of money for the animals.

Since the conservancy began putting the branded tortoises back into the wild in 2011, the shells have not come up in the black market, which officials believe is a good sign.

The Turtle Conservancy’s Behler Chelonian Center in Ventura County, Calif., has been working with ploughshare tortoises among others which originate from Madagascar. Their goal is to engrave the shells of both the ploughshares in captivity as well as those living in the wild…

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]


NEAT

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.)
