Could yeast experiments help us better understand the causes of mental retardation? Surprising as it may seem, researchers at CEA-IRTSV used the yeast model to explain the molecular origin of some cortex defaults in humans. These results were published in the scientific journal Nature Genetics.
Thanks to the improvements in imaging, scientists know better and better the anatomical anomalies which cause mental retardation. Cortex malformations and a malfunction of neuronal circuitry are (...)
Researchers have developed the first ever single-molecule LED. It seems like they crossed the finish line in the race to miniaturize light emitting diodes (LED).
A team of scientists led by the Institut de physique et de chimie des matériaux de Strasbourg (IPCMS, CNRS/Université de Strasbourg), working with UPMC and CEA, has just developed the first ever single-molecule LED. The device is composed of a single polythiophene wire placed between the tip of a scanning tunneling microscope and a (...)
Vesicles play an important part in exchanges between cells. Some vesicles may become drugs carriers. Physicists at CEA-Iramis conducted a study on their shape transformation.
How does the shape of vesicles immersed in concentrated solution change? Physicists at CEA-Iramis studied the shape of very rigid vesicles - polymersomes, after an osmotic stress. In particular conditions, they evidenced the formation of a double cell wall, inside which drugs could be encapsulated.
Vesicles are (...)
An international consortium led by CEA researchers in collaboration with the CNRS, has succeeded in characterizing the structure and function of a protein involved in the production of magnetite nanomagnets in magnetotactic bacteria. This protein, MamP, is crucial to the metallurgical activity of the bacterium. It is this protein that gives the magnetite its magnetic properties. This work constitutes an important advance in the understanding of these bacteria and the magnetite (...)
Astrophysicists from the CEA, CNRS and Bordeaux 1 and Paris-Diderot Universities, working on an international cooperation project, have identified the mechanism behind the formation of a star fifty to a hundred times the mass of the Sun, located 11,000 light-years away. The observations from ALMA have allowed the researchers to fathom the molecular cloud that is giving birth to this giant star. This research was published in Astronomy & Astrophysics on July 10.
Molecular clouds are (...)
From June 10 to August 10 2013, the CEA and CNRS are coordinating a major measurement campaign as part of the most comprehensive survey of atmospheric pollution in the Mediterranean region.
The goal of this international project, the Chemistry-Aerosol Mediterranean Experiment (ChArMEx), an integral part of Mediterranean Integrated Studies at Regional and Local Scales (MISTRALS), an international interdisciplinary metaprogram, is to improve our understanding of interactions between (...)
