Bacteria Can Transform Minerals Electrically -- Last 2009 (1217)
Got a messy cleanup problem that requires a molecule-by-molecule fix? Instead of nanotech, how about deploying an array of ready-made, versatile bacteria? Scientists studying a genus of the rock-dwelling bacteria called Shewanella have found out how the organisms can transform minerals by zapping them with tiny electrical currents. The discovery could lead to new types of fuel cells to generate electricity, to better environmental-cleanup techniques, and possibly even to a new generation of organically made materials. Bacteria live in almost every environment on Earth, from the ocean's deepest trenches to the Himalayas' highest peaks. Perhaps the main reason is their supreme adaptability.

Un article sur le site Physorg.com fait le point sur l’état d’avancement du Artificial Retina Project , piloté par le Department of Energy (DOE), l’équivalent du CEA aux Etats-Unis. C’est le programme le plus avancé en matière d’œil bionique, dont j’ai déjà parlé . On trouvera ici une courte vidéo présentant la chose.

Introduction
The initiative uses an agile, accelerated grant-making process with short two-page applications and no preliminary data required.
The 'Polymath Project' proved that many minds can work together to solve difficult mathematical problems. Timothy Gowers and Michael Nielsen reflect on the lessons learned for open-source science.

J'avoue, cette video est vraiment bien faite! Ca en fait même un peu trop... en vrai c'est pas toujours aussi exitant! Mais c'est cool que la BBC fasse de l'aussi bonne vulgarisation! by Nov 22
