Dear friends,

I am glad to announce that in 2013 the European Science Café will be back beginning on January 29th. During those events a consulate invites a European scientist to give a talk, followed by a discussion with the public around some refreshments. For the first 2013 European Science Café, Nicolas Florsch will talk about Mining engineers in the sixteenth century (in Europe).

In this month newsletter, you will discover that scientists are still hardly working on diabetes. Both French and American researchers are trying to understand mechanisms leading to the apparition of this disease and to find treatments.

I hope you had a great 2012 year, and I wish you all the best for this new year!

Have a good reading, and don’t forget the deadlines for the Chateaubriand and PUF fellowship!

Juliane Halftermeyer, Deputy Scientific Attaché in Life Sciences

Scientific news from the Southeast USA


- Mosquitoes as involuntary bioterrorists, Vanderbilt University (TN), 11/29/2012. GIF
Recent research, has revealed that mosquitoes have surprisingly sophisticated immune systems. Unlike humans and most other animals, mosquitoes do not generate antibodies that identify and attack specific infectious agents. However, they have developed alternative methods for destroying various pathogens, including parasites that cause malaria.

- UGA researchers find algal ancestor is key to how deadly pathogens proliferate, University of Georgia (GA), 12/12/2012. GIF
Long ago, when life on Earth was in its infancy, a group of small single-celled algae propelled themselves through the vast prehistoric ocean by beating whip like tails called flagella. It’s a relatively unremarkable tale, except that now, more than 800 million years later, these organisms have evolved into parasites that threaten human health, and their algal past in the ocean may be the key to stopping them.

- ’Molecular Levers’ May Make Materials Better, Duke University (NC), 12/24/2012. GIF
In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could use these molecular levers to drive chemical and mechanical reactivity among atoms and ultimately engineer more efficient materials.

Scientific news from France


- Attosecond “lighthouses”: a simple method for generating isolated ultrashort pulses, also available in French, CEA-IRAMIS, LOA, CNRS, ENSTA-Paris Tech, École polytechnique, 11/28/2012. GIF GIF
Electrons move extremely rapidly inside atoms and molecules (the order of magnitude is the attosecond, i.e. 10-18 of a second). One way to observe these phenomena is to use isolated ultrashort pulses of light, which are successfully characterized at this time scale. As demonstrated by researchers, there is a particularly well-adapted light source that can be used to carry out such research into how matter behaves.

- The radical restructuring of brain networks in comatose patients, also available in French, Inserm, CNRS, Université Joseph Fourier de Grenoble, 11/29/2012. GIF GIF
Researchers have analysed data from 17 comatose patients using functional MRI data. Their research reveals that the brain networks of these patients have been restructured.

- Improving chemotherapy effectiveness by acting on the immune system, also available in French, Inserm, 112/03/2012. GIF GIF
An Inserm team is to publish an article suggesting that two chemotherapy drugs frequently used to treat digestive and breast cancers may encourage the development of tumours by modulating the anti-tumoural immune response. These results reveal how the immune system can then limit the effectiveness of some cancer chemotherapies.

- Plants have the sense of straightness! (only in French), Inra, CNRS, 12/05/2012. GIF
At every moment, plants perform imperceptible movements that allow them to remain standing. They are indeed subject to the dual challenge of gravity and wind, and they can stay straight only through an active control. For the first time, researchers at INRA and CNRS showed that upright habit does not result from the mere perception of gravity: the plants must also perceive their own curvature and correct it.

- Microbicide gel blocks infection by the AIDS virus in preclinical research, also available in French, CEA, Université Paris-Sud, CNRS, 12/07/2012. GIF GIF
The efficacy of a microbicide gel in blocking infection by the AIDS virus has been demonstrated in a primate model. In this gel, small peptides trap the virus by mimicking its receptor on the surface of its target cells: the CD4 molecule. These results provide the proof-of-principle necessary prior to clinical trials.

- A promising clinical trial to reduce the severity of autistic disorders, also available only in French, Inserm, 12/11/2012. GIF GIF
Researchers recently published the results of a double-blind clinical trial to evaluate the usefulness of a diuretic in the treatment of autism. Sixty children between 3 and 11 years old with autism or Asperger’s syndrome were treated for 3 months either with a diuretic to reduce their intracellular chloride levels or with a placebo. Although this therapy is not curative, it nevertheless reduced the autistic disorders’ severity in three-quarters of the children.

- The role of the innate immune cells in the development of Type 1 diabetes, also available in French, Inserm, Université Paris Descartes, 12/18/2012. GIF GIF
Type 1 diabetes is a disease characterised by the self-destruction of the p pancreatic cells that produce insulin. The researchers reveal the role of the innate immune cells, especially the dendritic cells, that cause the activation of the killer T-lymphocytes whose action is directed against the p pancreatic cells. The results obtained in mice make it possible to consider new ways of regulating the auto-immune reaction generated by the innate immune cells.

- Reproducing and understanding evolution of bacteria in a test tube (only in French), LAPM, CNRS, Université Joseph Fourier-Grenoble, CEA, IG-Evry, 12/20/2012. GIF
The ability of bacteria to produce mutations, and thus to adapt, evolves according to their environment and their level of adaptation. Mutations in the genome of the bacteria are involved in their adaptive capacity and are, for example, responsible for the emergence of bacteria which are multi-resistant to antibiotics or bacterial pathogens responsible for nosocomial infections. Understanding the evolution of mechanisms that control the appearance of mutations is therefore essential to improve the fight against these microorganisms.
