"A 4.4 billion-year-old zircon crystal from the Jack Hills region of Australia has been confirmed to be the oldest bit of the Earth’s crust. To determine the age of the zircon fragment, the scientists first used a widely accepted dating technique based on determining the radioactive decay of uranium to lead in a mineral sample. But because some scientists hypothesized that this technique might give a false date due to possible movement of lead atoms within the crystal over time, the researchers turned to a second sophisticated method to verify the finding. They used a technique known as atom-probe tomography that was able to identify individual atoms of lead in the crystal and determine their mass, and confirmed that the zircon was indeed 4.4 billion years old.” (via Tiny Crystal Is Oldest Known Piece of Earth, Scientists Say - NBC News.com)

Thomas Haugersveen: Parkour in Gaza (2014)

Young Gazan are defying the limits of their body and a constant state of political tensions by practicing “Parkour” amongst the demolished buildings and cemeteries of the Gaza Strip.

First developed in Paris’ suburbs in the early 90’s, “Parkour” is an extreme sport that combines running, acrobatics and climbing in a urban environemnt. 

"Parkour" made its way to Gaza via the internet. Even though “Parkour” isn’t well accepted by their families, neighbours and local police, it allows the youth to meet in a friendly atmosphere and to share their common passion to go beyond their own limits. The experienced ones teach the youngest ones the basic moves, and this emerging « tradition » is transmitted from one generation to the next.

Julien Mauve | on Tumblr - After lights out (2013)

Night no longer exists. City lights cover up the stars, and cell phone screens lighten even the darkest of alleyways. And soon, imagine a world in which our lights render even the sun gratuitous. 

In the darkness of space, light is a beacon of hope. What if darkness in our world once again overtook the night and as an affect, transforming even the most insignificant light into an exception – a mystical phenomenon ? In a world in black and blue, the single incandescence of a bulb could be the greatest promise of an adventure about to start.”
