This program, which will last two years, provides a total investment of 20 million euros divided into four tenders, 6 months apart and dedicated to specific topics. The call for tender published in December last door on the sector Materials, Components and Sensors "and is planning an investment of 5 million euros for the creation of innovative technological solutions that find their place mostly in space activities. The business-plan business must demonstrate the validity of the solutions proposed by their ability to target market requirements that allow SMEs to grow their business. In addition, the
Radio Astronomy Works
The radiations received at radio wavelengths can be divided into two groups, thermal and non-thermal. In the thermal group the intensity of radiation depends on the temperature of the source. This radiation
Kepler analyzes the atmosphere of an exoplanet
The telescope’s space NASA has just offered a dip in the atmosphere of an exoplanet already known. The first test, a simple appetizer before the start of scientific work has demonstrated the exceptional performance of instruments and their ability to detect exoterres.
Apophis, the NEO that is afraid, will probably miss the Earth
The NASA has revised downwards the probability of a collision with the asteroid Apophis April 13, 2036. Discovered in 2004, this small celestial body of nearly three hundred meters will, for sure, shave Earth another April 13, in 2029. Many telescopes the hound.
A map of quasars in the service … GPS
What is the use of studying general relativity and the supermassive black holes located billions of light years? Would it not be better to spend money on practical problems, the useful life of all days? If the researchers had all followed this line of reasoning, we would not have today’s technologies such as Global Positioning [...]
Increased pollution is back …
1980s, we would have preferred a return of disco and color flashy. But they are persistent chemicals and toxic, banned last decade, returning. Indeed, melting alpine glaciers releases these pollutants in the inland waters. Christian Bogdal and colleagues from the Swiss Federal Institute of Technology in Zurich have studied the levels of a wide range [...]
Why males are often they colored
Why are there so many varieties of colors and shapes in birds, mammals or insects? Because of sexual selection, met Charles Darwin. Not just, say today Grether Gregory and Christopher Anderson of the University of California. The two researchers studied the behavior of species of lady’s kind Hetaerina to finally discover that the color of [...]
Nitrogen cycle refine climate predictions
For the first time, scientists have successfully introduced, the nitrogen cycle in climate simulations. The results cast doubt on previous assumptions on the feedback climate-carbon, which could improve the accuracy of predictive models of global warming. Published in Biogeosciences, the results of the experience of the Department of Energy’s Oak Ridge National Laboratory (ORNL) and [...]
Amazing regeneration of zebrafish finally understood
Very popular with researchers, the zebrafish has the amazing ability to regenerate indefinitely its members and even his eyes or his heart. The secret: fish awakens sleeping arrangements since infancy. The hope to emulate this approach in humans. “Until now it was like magic that the amputation had resulted in the activation of genes, said [...]
Acidification of the ocean species will benefit, others will die
What effect will have on marine organisms to ocean acidification, another consequence of the increased content of the atmosphere as carbon dioxide? A U.S. team has measured experimentally on a range of species. Moral: there will be winners and losers. As the atmosphere becomes richer in carbon dioxide (CO 2 dioxide or carbon), the pH [...]
Salt Found on Mars
NASA has found an ancient salt deposit in the southern highlands of Mars. Salt is an indicator of where water once flowed and could point to a good place to search for ancient life
