- Le ver plat peut régénérer son corps à partir d’une seule cellule, USA, 05/30/2011. GIF
Depuis que l’on sait que les lézards et les étoiles de mer ont la capacité de régénérer certaines parties de leur corps une fois sectionnées, les scientifiques se demandent quel type de cellules sont à l’origine de ce phénomène. Dans le cas du ver plat, également appelé planaire, des chercheurs ont déterminé que la régénération était due à un seul type de cellules, appelées néoblastes clonogéniques (c-néoblaste), cellules souches pluripotentes, ayant des propriétés apparentées aux cellules souches embryonnaires humaines.

- Computer Science Research Profile: Designing an HIV Vaccine, Duke University (NC), June 2011. GIF
Biologists have worked for decades and spent hundreds of millions of dollars to develop a safe and effective vaccine against HIV, but with little success. Today, the medical community is turning to computer scientists, computational biologists, and statisticians to help understand how HIV continues to evade our best efforts to activate the immune system against it. Together, they hope, we can finally design a vaccine to beat the virus.

- Des racines pour lutter contre le cancer du sein métastatique, Emory University (GA), 06/10/2011. GIF
Des études menées par le chercheur José Thaiparambil au Winship Cancer Institute de l’Université d’Emory ont montré qu’une molécule, la withaférine-A, empêche les cellules cancéreuses situées au niveau du sein de métastaser (multiplication et migration). Lorsque cette molécule, extraite de racines de la plante Withania somnifera utilisée en médecine traditionnelle indienne, a été administrée aux souris, aucune migration des cellules cancéreuses dans des tissus voisins n’a été remarquée.

- Comment utiliser les ondes magnétiques pour influencer la différenciation des cellules souches ?, USA, 05/20/2011. GIF
De nombreuses thérapies contre les maladies dégénératives ont recours aux cellules souches. Toutefois, être capable de fabriquer des cellules souches et de les différencier par la suite en un type cellulaire désiré (tel que des cellules des muscles, de la peau, des vaisseaux sanguins ou des os) est soumis à des contraintes qui limitent le potentiel de ces biotechnologies.

- SIV-resistant monkeys close the gates to viral infection, Emory University (GA), 06/27/2011. GIF
Sooty mangabeys, a type of African monkey, have intrigued scientists for years because they can survive infection by SIV, a relative of HIV, and not succumb to AIDS.

- Transparency in health care: Are you ready?, The University of Alabama in Birmingham (AL), 06/29/2011. GIF
If you could know the cost for a chest X-ray in advance, would you choose a clinic that charges $121 or one that charges $1,519? For heart-bypass surgery, would you choose a hospital with the best possible outcome measures for $45,000 or one with the lowest possible rating that costs $32,000? How would you weigh the hospital’s national reputation in your decision?

Scientific news from France

- Detecting Tumoral DNA in Droplets of Biological Fluids, also available in French, Bulletins électroniques, 05/30/2011. GIF GIF
When tumoral cells die, they spill their contents, including DNA, into the extracellular medium. The contents can then be found in a patient’s biological fluids (e.g., blood, lymph, urine). Since the development of most cancers involves genetic factors, a simple blood or urine test could theoretically reveal the presence of the DNA and thus cancer.

- When Jupiter was in the position of Mars, also available in French, CNRS, 06/09/2011. GIF GIF
A new scenario describing a key step in the formation of the solar system has been proposed by a French-American collaboration including researchers from CNRS and Nice and Bordeaux 1universities. According to this model, Jupiter migrated towards the Sun to the position where Mars is today before beginning its outward migration to its current location, much further away.

- "Plant milking” wins technology transfer award also available in French, INRA, 06/10/2011. GIF GIF
On 6 June, 2011, the Joint Research Unit for Agronomy and the Environment (LAE) (INRA, INPL-ENSAIA) in Nancy was recognised for its contribution to one of the “ten most successful examples of technology transfer” by CURIE, a public research promotion network. The prize rewards a remarkable success story based on an innovative technique developed by the LAE: the “milking” of plants to extract plant molecules for pharmaceutical and cosmetic use.

- Mimivirus isolated, genome amputated also available in French, CNRS, 06/10/2011. GIF GIF
In the absence of competition with other microorganisms, Mimivirus, the largest known DNA virus, loses 17% of its genome. This has recently been demonstrated by a French-American collaboration including researchers from CNRS, the Université de la Méditerranée and the Université de Provence.

- Migraine: it’s in the genes, INSERM, 06/14/2011. GIF
It is estimated that migraine affects 20% of the general population, i.e. 11 million people in France. For the first time, Tobias Kurth, director of research at Inserm unit 708 "Neuroepidemiology", and his international collaborators, have identified three genes, each of which has a genetic variation associated with an increased risk of migraine among the general population.

French National Research Agency Call for Proposal

France and Germany share a common vision and instruments for the development of technological research. Carnot institutes (IC) and Fraunhofer institutes (FhI) are institutes dedicated to the development and transfer of science and technology to the benefit of the economy and society.
Following the French-German Forum for Research 2008, the ANR and the BMBF agreed, in a Memorandum of Understanding, on a 3 years joint-programme, funding German-French collaborative research and innovation projects between the FhI and the IC.

PhD Positions, Modeling of Structure and Microporosity Formation during Solidification of Aerospace Aluminium Alloys, Ecole des Mines de Nancy

The work will consist of modeling of (1) the multiphase flow: this involves the dynamics of free-floating solid grains, phenomena of grain sedimentation and packing, and flow through the porous packed layer; (2) the formation of microporosities: the phenomena involved are the transport of dissolved hydrogen, pressure relations and the nucleation of gaseous bubbles.
Duration 36 months, starting date between September 1, 2011 and November 1, 2011
Scientific Supervisors: Herve Combeau, Professor at Ecole des Mines de Nancy Miha Zaloznik, Associate Scientist CNRS

Jets from Unusual Galaxy Centaurus A

Credit: ESO/WFI(visible); MPIfR/ESO/APEX/A. Weiss et al. (microwave); NASA/CXC/CfA/R. Kraft et al. (X-ray); Inset: NASA/TANAMI/C. Müller et al. (radio)

Jets of streaming plasmaexpelled by the central black hole of a massive spiral galaxy light up this composite image of Centaurus A. The jets emanating from Cen A are over a million light years long. Exactly how the central black hole expels infalling matter is still unknown. After clearing the galaxy, however, the jetsinflate large radio bubbles that likely glow for millions of years. If excited by a passing front, radio bubbles can even light up again after a billion years. X-ray light is depicted in the above composite image in blue, while microwave light is false-colored orange. The inset image in radio light shows newly imaged, never seen-before details of the innermost light year of the central jet.
