- Science: Investigating new materials with ultracold atomsYesterday
- The investigation of complex materials such as high-temperature superconductors is problematic because of the presence of disorder and many competing interactions in real crystalline materials. 'This makes it difficult to identify the role of specific interactions and, in particular, to decide whether repulsive interactions between electrons alone can explain high-temperature superconductivity,' says Dr Theodoulos Costi from the Institute of Solid State Research, Forschungszentrum Juelich, which is a member of the Helmholtz Association...
- Mars Science Laboratory mission rescheduled for 2011Yesterday
- NASA's Mars Science Laboratory will launch two years later than previously planned, in the fall of 2011. The mission will send a next-generation rover with unprecedented research tools to study the early environmental history of Mars. A launch date of October 2009 no longer is feasible because of testing and hardware challenges that must be addressed to ensure mission success. The window for a 2009 launch ends in late October. The relative positions of Earth and Mars are favourable for flights to Mars only a few weeks every two years. The next launch opportunity after 2009 is in 2011...
- Happiness is a collective - not just individual - phenomenonYesterday
- If you're happy and you know it, thank your friends - and their friends. And while you're at it, their friends' friends. But if you're sad, hold the blame. Researchers from Harvard Medical School and the University of California, San Diego have found that 'happiness' is not the result solely of a cloistered journey filled with individually tailored self-help techniques. Happiness is also a collective phenomenon that spreads through social networks like an emotional contagion...
- Virtual faces created with emotions, moods and personalityYesterday
- A team of researchers from the University of the Balearic Islands (UIB) has developed a computer model that enables the generation of faces which for the first time display emotions and moods according to personality traits. The study has been published in the latest edition of the magazine Computer Animation and Virtual Worlds...
- Experiment shows potential for vegetation to recover at the Sierra Nevada ski stationYesterday
- Preparation work on the ski slopes in Spain's Sierra Nevada destroys a large number of plant species. In their efforts to develop new methods to restore plant cover, researchers from the University of Granada have now successfully grown the area's two native shrub species in the laboratory. They hope to use these to guarantee the biodiversity of the Sierra Nevada National Park...
