A 15-unit apartment building has been constructed in the German city of Hamburg that has 129 algae filled louvered tanks hanging over the exterior of the south-east and south-west sides of the building—making it the first in the world to be powered exclusively by algae. Designed by Arup, SSC Strategic Science Consultants and Splitterwerk Architects, and named the Bio Intelligent Quotient (BIQ) House, the building demonstrates the ability to use algae as a way to heat and cool large buildings.
To make use of the algae, which the team retrieved from the nearby Elbe river, it was put into large thin rectangular clear cases. Inside, the algae live in a water solution and are provided nutrients and carbon dioxide by an automated system. Each tank was then affixed to the outside walls of the building onto scaffolding that allows for turning the tanks towards the sun—similar to technology used for solar collectors. As the algae grows—mostly in the summer—it provides more shade for the building, helping to keep it cool (and serves as a sound buffer as well). Excess heat that builds up in the water in the tanks is transferred to saline water tanks underneath the building for use later. When the amount of algae growth in the tanks reach a certain point, some is harvested and taken to a processing facility inside the building. There the biomass is converted to biogas which can be burned to provide heat in the winter. Thus, the building makes use of both solar thermal and geothermal energy allowing it to be heated and cooled without using any fossil fuels.
The design and construction of the BIQ has taken three years and has cost approximately €5 million, all funded by Internationale Bauausstellung (IBA) as part of the ongoing International Building Exhibition – 2013. The BIQ House is one of 16 projects undertaken by the group, with the goal of proving that cost effective ways of making bio-friendly buildings are available today. To highlight the building, the team has painted its exterior green and has added a giant cartoon-like bubble on one side with the word "Photosynthesis?" in it.
The building is to serve as a test case and will be studied by various architects and engineers from around the world to determine if the design is feasible and if so, to perhaps serve as a model when erecting buildings in other cities.

"Une nouvelle classe de médicaments s'est montrée efficace contre certaines souches pharmaco résistantes du virus de la grippe d'après une étude menée par des chercheurs de l'Université de Colombie-Britannique de Vancouver (UBC). Celle-ci, publiée en ligne récemment dans Science Express, détaille le développement d'un nouveau médicament candidat qui empêche le virus de la grippe de se répandre d'une cellule à une autre. Ce médicament a traité avec succès des souris infectées par des souches mortelles du virus." Image : http://www.allodocteurs.fr/upload/article/6262-recherche_grippe2.jpg

"La flore intestinale représente environ dix fois plus de bactéries que le nombre de cellules constituant le corps humain, et ces "passagers" sont extrêmement importants pour notre santé : Ces bactéries de la flore commensale nous aident à digérer les aliments et nous fournissent de l'énergie et des vitamines. Elles sont également un vecteur de protection contre certaines infections, par exemple par les salmonelles. Elles participent par ailleurs aux réactions biochimiques nécessaires au développement et au fonctionnement du corps."

In Patrick's lab I developed methods for SEM and TEM imaging of these microbes to investigate their phenotypic character evolution, functional morphology, and symbioses with bacteria in the light of molecular phylogenetic data.
Energy Department announced new innovative projects to develop advanced drop-in biofuels for military jets and ships. Up to 6.4 M USD was awarded to the BioProcess Algae project that will evaluate an innovative algal growth platform producing hydrocarbon fuels. These are meeting military specifications using renewable carbon dioxide, lignocellulosic sugars and waste heat. The proposed biorefinery will integrate low-cost autotrophic algal production, accelerated lipid production, and lipid conversion.
