The New Partnership for Africas Development (NEPAD), held a Water Access workshop between 9 and 12 May. The aim of the event, bringing together specialists from Africa and France, was to set up a network of African Centres of Excellence in Water Science and Technology. It was supported by the Institut de recherche pour le développement (IRD). An action plan is to be put forward to decision makers anxious to meet the many challenges that face efforts to provide access to water resources and their management on the African continent.
African leaders have identified the scarcity of water as one of the main obstacles to development in Africa.
The Johannesburg Sustainable Development Summit of 2002 resulted in a number of fixed objectives to be met by 2015. Crucial among these: a halving of the numbers of people devoid of access to drinking water.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
