"Researchers have found that E. coli can be used to recover uranium from tainted waters and can even be used to clean up nuclear waste. Using the bacteria along with inositol phosphate, the bacteria breaks down the phosphate — also called phytic acid — to free the phosphate molecules. The phosphate then binds to the uranium forming a uranium-phosphate precipitate on the cells of the bacteria. Those cells can then be harvested to recover the uranium." What has made this 14-year-old process economically feasible is the use of inositol phosphate, which is a cheap waste material from the production feedstock from plant material.

Why the Linux world should embrace the BSD's Imprimer
Écrit par anonymous   

Steve Lake over at Raiden's Realm puts up a very good argument in his latest piece about why Linux should join or partner with the BSD's to become the biggest and best operating system in the world. The arguments are very solid and well worth considering, because there appears to be a lot the BSD's can offer the Linux world, and vice versa. In the end the partnership would benefit everyone.

200,000 DVDs on a single disc ? Imprimer
Écrit par anonymous   

Imagine being able to put your entire DVD collection on a single disc. And not just your collection, but also that of your family, friends and neighbours ... the contents, in fact, of as many as 200,000 DVDs.

It sounds a stretch of imagination, but this is the aim of Professor Min Gu and his team at Swinburne University of Technology's Centre for Micro-Photonics.

They are three years into a fiveyear project that is looking at how nanotechnology — particularly the use of nanoscopic particles — can be used to exponentially increase the amount of information contained on a single disc.

The full story is available from the Swinburne Magazine
