Dear friends,

This month, the French American collaboration between CNRS and Georgia Institute of Technology presented some great results on graphene, in a paper published in Nature Physics, showing production semiconductor nano-graphene ribbons.

You will also learn in this month’s newsletter that researchers from Duke university are still improving their invisibility cloak, while French scientists developed a “sonar vision” system that enables people who are blind from birth to perceive the shape of a face, a house or even words and letters.

I wish you Happy Holidays.

Have a good reading,

Juliane Halftermeyer, Deputy Scientific Attaché in Life Sciences

- New Alzheimer’s risk gene identified, Emory University (GA), 11/15/2012. GIF
Researchers have identified a new genetic variation that confers an increased risk for late-onset Alzheimer’s disease. The new variant increases risk by about a factor of three, an effect that is similar in size to that of the most common genetic risk factor for Alzheimer’s, ApoE E4. However, the new variant is more rare: it is found in one in every 160 people in Iceland, compared to more than 17 percent of the population for Apo E4 and higher in other countries.

- History of porpoises from the Black Sea reconstructed using genetics (only in French), Museum national d’Histoire naturelle, CNRS, Universités Paris Diderot et Paris-Sud, 11/19/2012. GIF
Over the past five decades, overexploitation of fish stocks and hunting small cetaceans led porpoises from the Black Sea at the edge of extinction. Previous studies have suggested that the decline of Black Sea’s predators between 1960 and 1980 constituted the major part of the loss of resilience of the Black Sea’s ecosystem, but to highlight the importance of the decline of these predators.

- A major advance in microelectronics : production of semiconductor nano-graphene ribbons (only in French), CNRS, Georgia Institute of Technology, 11/19/2012. GIF
Graphene, two-dimensional crystal composed of a single layer of carbon atoms, has properties very promising for electronics. However, to realize these potential applications, it was necessary to obtain a semi-conductive form of this material. Eight years after its discovery, this is done through the work of a French-American team.

- Risky business: drought stretches tree plumbing to its limits, also available in French, Inra, 11/21/2012. GIF GIF
Beneath the bark of world’s trees pulses a finely tuned vascular system that transports billions of litres of water to the skies every day. This plant hydraulic system depends on a unique but unstable mechanism that is continuously challenged by environmental stress. Researchers has found that most trees, even those in rainforests, operate very close to their hydraulic safety threshold leaving them highly vulnerable to droughts of increased severity.
