Clinton puts science at heart of US development strategy
In an unprecedented endorsement of Science Technology and Innovation (STI) in development, Clinton said: "While talent may be distributed universally, opportunity is not. And the reality of the world we live in today is that technology and innovation are the great equalisers and can be used to create opportunity where there is very little of that commodity." |

Fishing for Oxygen
Oxygenating a fish pen with a standard hose in the open sea would create such big bubbles that they would float to the surface and dissipate into the air, bypassing the
fish. The resulting unique OxyVision system consists of a grid of rubber hoses that is sunk about 10 meters down inside a net pen. Pure oxygen is then pumped through the system for dispersion throughout the whole volume of the pen. Micro pores ensure that oxygen is properly dissolved in the water and is spread vertically over large areas. |
