- Fire Ants Surf Floods on Rafts of Their Own Bodies also available in French, Georgia Tech, 04/25/2011. GIF GIF
Fire ants are depressingly resilient. Colonies of the aggressive, stinging insects can withstand floods, fires, and pesticides. Now, researchers have revealed the mechanisms behind one of the bug’s neatest survival tricks: rafts composed of thousands of ants linked together, which repel water and sometimes float for months.

- When HIV Doesn’t Make You Sick- New Research Shows a Handful of Humans with HIV Can Cope Similarly to AIDS-Resistant Monkeys, Emory University (GA), 05/19/2011. GIF
For a few people, HIV appears to be just another virus. These rare individuals, called viremic nonprogressors (VNPs), can tolerate high levels of HIV in the body without the immune system going into overdrive. Similarly, some types of Old World monkeys, such as sooty mangabeys, have the ability to withstand infection by SIV, the cousin of HIV, and not end up with crippled immune systems.

- Defect in graphene may present bouquet of possibilities, Georgia Institute of Technology (GA), 05/25/2011. GIF
A class of decorative, flower-like defects in the nanomaterial graphene could have potentially important effects on the material’s already unique electrical and mechanical properties. In a new paper, the team for the first time describes a family of seven defects that could occur naturally or be induced to occur in graphene, one of which already has been observed.

Scientific news from France

- Insects with 3 pairs of wings also available in French, CNRS, 05/04/2011. GIF GIF
In 250 million years of insect evolution, the appearance of new wings is unprecedented. Transformations and losses of wings, yes, but additions, never. A team has shattered this belief by providing proof that the exuberant helmet of Membracidae, a group of insects related to cicadas, is in fact a third pair of profoundly modified wings.

- Five New Genetic Susceptibility Factors Identified for Alzheimer’s Disease, also available in French, eTech France, 05/17/2011. GIF GIF
The number of patients with Alzheimer’s disease is rising in France and worldwide due to humans’ increased life span. European researchers have decided to pool their skills and expertise to combat the disease that is now the leading cause of memory and intellectual function disorders in the elderly.

- The first habitable exoplanet : a new candidate revealed by climate scientists, also available in French, CNRS/UPMC/ENS/Ecole Polytechnique, 05/16/2011. GIF GIF
The planetary system around the red dwarf Gliese 581, one of the closest stars to the Sun in the galaxy, has been the subject of several studies aiming to detect the first potentially habitable exoplanet. Two candidates have already been discarded, but a third planet, Gliese 581d, can be considered the first confirmed exoplanet that could support Earth-like life.

- Droplets for detecting tumoral DNA, also available in French, CNRS, Inserm, Paris Descartes and Strasbourg universities, 05/20/2011. GIF GIF
The mantle of Mars is possibly cooling by 30-40°C every billion years. Based on satellite observations of the composition of the planet’s volcanic rocks, researchers reached this conclusion after reconstructing for the first time the thermal evolution of the planet over the past 4 billion years.

- The rejection of a graft filmed in 3-D at the cellular level presented by Philippe Bousso, Immunologist, also available in French, Inserm, Pasteur Institute, 05/16/2011. GIF GIF
Using a novel, in vivo imaging technique which allows in-depth real-time exploration of immunity mechanisms on the cellular level in animals, researchers from Inserm and Institut Pasteur have been able to visualize the graft rejection process for the first time. The observation of this "cellular choreography" has demonstrated the existence of a mechanism which contributes to the immune reaction responsible for rejection.

Two Winners of the Nobel Prize in Physiology or Medicine will be giving seminars in Atlanta in June

Dr. Andrew Fire, Winner of the 2006 Nobel Prize in Physiology or Medicine and Professor in the Departments of Pathology and Genetics at Stanford University School of Medicine will give a talk called “Sequence-based tracking of biological responses to foreign information". His seminar will be held on Thursday, June 2, 2011 from 11:00am to 12:00pm at Georgia Tech in the Marcus Nanotechnology Building, Room 1116. A reception honoring Dr. Fire will be held in the gallery immediately following the seminar.

Pr. Françoise Barré-Sinoussi, Winner of the 2008 Nobel Prize in Physiology or Medicine, co-Chair of the United Nations Panel on AIDS, Director of the Retroviral Infections Regulation Unit at the
Pasteur Institute, and incoming President of the International AIDS Society will give a talk called “From the Discovery of HIV to the End of AIDS: A Discussion of Scientific Questions Past, Present, and Future". Her seminar will be held on Thursday, June 16, 2011 from 6:30pm to 7:45pm at Emory University in the Woodruff Health Science Center Administration Building, Plaza and Auditorium (1440 Clifton Rd). A reception honoring Pr. Barré-Sinoussi will be held before (6:00pm) and after (7:45pm) the seminar.

Where are the scientific competitiveness clusters in France?

A competitiveness cluster is:
- A joint theme-based initiative for a given geographic area: it is an initiative that brings together companies, research centers and educational institutions in order to develop synergies and cooperative efforts. Other cluster partners may include local and national authorities and services catering to cluster members.
- A chance to become a leader: clusters use synergies and innovative joint projects to give their member companies a chance to be national and international leaders in their fields.

In France, there is many scientific competitiveness clusters: Lyonbiopôle, Aerospace Valley, Medicen Paris Region, Alsace Biovalley...
You can subscribe to the english newsletter of the competitiveness clusters. Each competitiveness cluster has its own newsletter, most of the time, in french.

Drops of dried blood taken from a healthy individual (left) and an anemic patient (right)

Drops of dried human blood, taken from a healthy individual (left) and an anemic patient (right) that is to say, suffering from a lack of hemoglobin. Drying revealed regular patterns that vary only according to the composition of blood.
On the right picture, the drop of dried blood does not show large cracks visible on the drop of dried blood taken from the healthy individual.
They are a source of information on the health of the individual. Researchers are trying to develop a new method of diagnosing diseases affecting blood composition, based on observation of samples of dried blood. They will establish the fingerprint characteristic of a large range of diseases and build a database for analyzing these patterns reliably. This technique would avoid multiple and expensive tests that are currently used.
