Students from the Technical University of Darmstadt (Hesse) developed an apparatus to avoid adopting poor posture and thus prevent the adverse consequences that result.

Back pain is now the most widespread disease of approximately 60% of 30-60 years suffering in Germany. The main cause of this pain is poor posture and the fact that patients do not perceive they have poor posture before feeling the effects.

The device developed, hardly bigger than a USB drive, must be glued to the skin. Inside, a microprocessor constantly compares the position of the user with a defined position as its ideal position after individual settings. If the person stays in an unfavorable position for more than 60 seconds, the device will vibrate to indicate to the user to take a suitable position. The operation and use of the device are very simple. It does not bother the user and is not visible under clothing.

In addition to discipline the user, the camera records the position back in the days and weeks. The person can then obtain the ratio of time spent in a bad position with respect to time spent in a proper position and evaluate improvements. The inventors of the device are already planning changes to their product. By combining a GPS chip in it, the user could know where it is most often poor posture (sitting in the office or eating for example) and could take steps to correct his bad habits.

Researchers at the Max Planck Institute of Neurobiology in Martinsried (Bavaria) found in association with Scientific American and Dutch, the anticancer drug Taxol can promote regeneration of spinal cord after injury. The results were published online January 27, 2011 on the site of the magazine “Sience” [1].

The most common consequence of a crash or injury to the nerves of the spinal bone paraplegia [2]. This disease is incurable so far because the cells of the central nervous system (CNS) [3] are unable to renew themselves, unlike the nerves of the peripheral nervous system. Many teams have examined the difference between the neurons of both systems to understand the causes of this inability to regenerate in the CNS. Many factors stunting were found in the environment of the damaged cells. Two key elements are limiting the disruption of the cytoskeleton [4] in damaged cells that prevents their growth and formation of scar tissue that separates the two ends of the spinal cord and prevents their attachment.

The super-resolution microscopy , also known as nanoscopy , allows the mapping of a population of individual molecules on the surface of living cells . Simply being genetically modified organisms to make them fluorescent , which is one drawback . Hence the interest of the new technique of ” firing “of these molecules developed by physicists at the Centre for Superconducting and Hertzian biologists and Cell Physiology Laboratory of Synapse , two units of CNRS / University of Bordeaux .

This uses the immuno – marking in real time . The living cells are placed in the presence of a fluorescent antibody solution which will bind to it . But instead of using enough antibodies to bind to the molecules to study , the researchers achieved a mark diluted under the microscope. So the few available antibodies will then bind to molecules to study and make them bright. Then , when they will be extinct , other molecules will already bind to antibodies arriving in the new sample and light up in turn.

Chomik ( Hamster in Polish ) is the name given to spike soon Geological responsible explore Phobos , the larger of the two moons of Mars. Developed by the Center for Space Research of the Polish Academy of Sciences ( CBK – Centrum Badan Kosmicznych ” in Warsaw) , Chomik be incorporated into the Russian space mission Phobos – Grunt . His task will be to penetrate the surface of Phobos , to determine the mechanical and thermal characteristics , and retrieve samples for analysis on Earth with a return capsule.

The constraints of the workplace , as well as the obvious technological constraints no lack : space block ” slapper ” limited to the size of a large jar of jam , and available capacity of the order of watts , obvious constraint of weight but also irregularity of the hardness of the probe body (an estimated 1.9 g/cm3 , a high porosity ) and a very low gravity allowing only low kickback when the drums. Engineers and scientists have again CBK show their know -how . They developed a tool : a large cylindrical capacitor accumulates the low energy available for release to the chosen frequency striker block , which is located in the center of the capacitor.

Whether for data processing in medical devices or automatic control for electric vehicles, microelectronic systems will in future be miniaturized and energy efficient while still offering more features.

A method for achieving these objectives is the 3D system integration. It must mean the distribution of electronic components and their interactions in a 2D universe, rather than on silicon plates dimensional example, but in 3D. In this context, the new center-Fraunhofer IZM ASSID (All Silicon System Integration Dresden) [1] has just been inaugurated in Dresden (Saxony). New technology for 3D system integration and marketing must be developed within it.

At the heart of the mountains, watersheds small, steep and often barren, channel suddenly rains to the rivers and streams, causing erosion, so, overflows and floods. The problem is particularly concerned that local actors in charge of risk prevention does not currently have sufficient capacity to anticipate these events and brutal severity. Certainly the hydrometeorological radar C-band or S, with a range of about 120 km, used plain by Meteo-France for measuring real-time rainfall, can anticipate hazardous events such as flash floods. But the screen are the reliefs prevent this radar network, called ARAMIS (Application Radar Infra-Synoptic Meteorology), for the central Alps and Pyrenees. As the network of rain gauges installed on the ground, it does not account for precipitation, they vary greatly from one place to another mountain.

Bacterial pathogen responsible for human listeriosis, Listeria monocytogenes is particularly known for its ability to enter cells and manipulate different cellular functions for its own benefit in order to evade host defenses. These strategies enable the group to cross the intestinal barrier and other barriers to the body during infection in humans. Researchers from two units of the Institut Pasteur, Unit-Cell Interactions bacteria “led by Pascale Cossart and Unity” Nuclear Organization and Oncogenesis “whose responsibility is Anne Dejean, in collaboration with a team from the University Ghent, Belgium, found that Listeria produces a toxin that destroys SUMOylation. This is a very important cellular machinery that normally enables the cell to add some small protein called SUMO module, whose characteristic is to change the properties of target proteins. But Listeria blocks the addition of these modules, block proving essential for infection to be effective.
