Graphene Makes Water Purification More Efficient
The availability of fresh water is dwindling in many parts of the world, a problem that is expected to grow with populations. One promising source of potable water is the world’s virtually limitless supply of seawater, but so far desalination technology has been too expensive for widespread use.
Now, MIT researchers have come up with a new approach using a different kind of filtration material: sheets of graphene, a one-atom-thick form of the element carbon, which they say can be far more efficient and possibly less expensive than existing desalination systems.

Strata is a term we use in geology and stratigraphy, which is the rock layers/bands clearly defined like in the photo above. The word stratum is for one layer, whereas strata is for multiple layers. The photo above is by calwest on Flickr, which is a photograph of the Badlands in South Dakota.
Japanese artist Yayoi Kusama - who has notably lived in a psychiatric institution for the last four decades - has been obsessed with dots and infinity for her entire career, an inspiration she attributes directly to her hallucinations. In an attempt to share her experiences, she creates installations that immerse the viewer in her obsessive vision of dots or infinitely mirrored space.
