This is a breakthrough because, until now, only molecules that stabilize or destroy the cytoskeleton of actin have been available. These compounds with novel properties, whose action has been elucidated both in vitro and in vivo, provide a new tool in pharmacology.

This was made possible by combining approaches from biomimetic and protein chemistry. The results will lead to use of the wide variety of hydrogenase enzymes found in nature, and even the possibility of 'invented' artificial enzymes over the long term, which may potentially serve as catalysts for fuel cells or the production of hydrogen from sources of renewable energy. The results were published online in Nature on 26 June 2013.]]> Mon, 24 Jun 2013 01:00:00 +0200 http://www2.cnrs.fr/en/2237.htm Thu, 20 Jun 2013 01:00:00 +0200 http://www2.cnrs.fr/en/2235.htm Current Biology, the work provides important insights into the evolution of ecological communities at a time when certain are being disrupted by climate change and the arrival of invasive species.]]> Mon, 17 Jun 2013 01:00:00 +0200 http://www2.cnrs.fr/en/2231.htm Advanced Functional Materials and Chemistry: A European Journal, has made it possible to obtain molecules of low molecular weight with an electrical conversion efficiency above 4 %.

The scientists found that the genome of this extremely abundant single-celled microorganism contains one third more genes than the human genome, but is twenty times smaller. Another surprising finding is the complexity of this genome, which gives Emiliania a high adaptation capacity.

The genome of Chondrus crispus, also known by the Breton name 'pioka', turns out to be small and compact for a multicellular organism. It has fewer genes than several other species of unicellular algae, which raises a number of questions about the evolution of red algae. This low number of genes could explain why these organisms never colonized dry land, unlike their green counterparts—from which all terrestrial plants are descended. These findings open up new perspectives on the natural history of algae and of terrestrial plants.

They have determined the role of the corticosterone (stress hormone) receptor, in the long-term behavioral change triggered by chronic stress. In mice subject to repeated aggressions, this receptor participates in the development of social aversion by controlling the release of dopamine², a key chemical messenger. If this receptor is blocked, the animals become “resilient”: although anxious, they overcome the trauma and no longer avoid contact with their fellow creatures.
